Percepción de riesgo, eficacia preventiva y factores socio demográficos como predictores de conductas preventivas de COVID-19 en adultos chilenos / Risk perception, preventive efficacy and social factors as predictors for COVID-19 preventive behavior in chileans

BACKGROUND: Social isolation and hand washing are effective measures to prevent COVID-19 transmission Aim: To evaluate the predictive role of risk perception and preventive efficacy perception, along with sociodemographic and health factors, for adherence to hand washing and isolation behavior of Chilean adults. MATERIAL AND METHODS: In a Web-based cross-sectional study, 695 adults between 18 and 60 years old answered the COVID-19 Risk Perception Scale and a questionnaire on perception of preventive efficacy, preventive adherence, sociodemographic and health variables. RESULTS: Seventy seven percent of respondents adhered to hand washing and 71% to isolation behavior. The average risk perception of respondents was 67.2 ± 12.6%. Age, gender and perception of risk (considering its affective component and preventive efficacy perception), were identified in two predictive models as factors associated with compliance with hand washing. Conclusions: Preventive behaviors are associated with several psychosocial factors, allowing to distinguish groups at higher risk, which should be the focus of COVID-19 preventive interventions.

Prevalencia de síndrome de intestino irritable en América Latina / Irritable bowel syndrome prevalence in Latin America

El síndrome de intestino irritable es una enfermedad funcional intestinal frecuente a nivel mundial, pero con pocos estudios de prevalencia. Su diagnóstico es clínico y se basa en criterios acordados internacionalmente que han cambiado con el tiempo, actualmente regidos por el Consenso de Roma IV. Objetivo: Recabar y actualizar datos disponibles de prevalencia de América Latina para entender mejor el comportamiento regional de SII. Materiales y métodos: Se realizó una búsqueda de trabajos originales, autodefinidos de prevalencia, en las bases de datos Pubmed y Lilacs así como presentaciones en congresos de trabajos originales. Resultados: Se encontraron 27 estudios según los criterios de búsqueda establecidos. De ellos, 16 eran en población general. Dos trabajos incluyeron el estudio de prevalencia de más de una población constituyendo finalmente 22 referencias desarrolladas en 9 países. La prevalencia promedio total para América Latina fue 15,4%. La prevalencia promedio encontrada por criterios de Roma II fue 23,5%; por Roma III 11,8% y por Roma IV 6,98%. Conclusión: Esta es la primera revisión en reunir datos de prevalencia de síndrome de intestino irritable en población general de nueve países de América Latina. La prevalenci d fue amplia y los criterios diagnósticos utilizados hicieron la mayor diferencia.

Although irritable bowel syndrome is a common functional bowel disease worldwide, few prevalence studies have been published. Diagnosis is clinical and based on internationally agreed criteria that have changed over time. Currently the Rome IV Consensus is used as the international reference. Objective: collect and update available prevalence data from Latin America to better understand the regional behavior of irritable bowel syndrome. Materials and methods: a search was carried out for original works, self-defined on prevalence, in the Pubmed and Lilacs databases. Presentations or posters at congresses of original works were also considered. Results: according to the established search criteria, 27 studies were found. Of these, 16 were in the general population. Two studies included the study of the prevalence of more than one population, for which reason 22 prevalence data were obtained from 9 countries. The total average prevalence for Latin America was 15.4%. The average prevalence found by the Rome II criteria was 23.5%; by Rome III 11.8% and by Rome IV 6.98%. Conclusion: this is the first review to collect data on the prevalence of irritable bowel syndrome in the general population from nine Latin American countries. The average prevalence found was 15%. The variability was wide and the diagnostic criteria used made the biggest difference.

Dietas vegetarianas en alumnos universitarios / Vegetarian diets in first year university students

INTRODUCCIÓN: Se ha observado un aumento en la popularidad de las dietas vegetarianas, en especial en la población adolescente y adulto joven. Estas dietas se presentan como saludables y balanceadas pero las recomendaciones son controversiales en cuanto a los potenciales déficit nutricionales. OBJETIVO: Identificar la frecuencia y tipos de dieta vegetariana utilizada, su motivación y fuentes de información. PACIENTES Y MÉTODO: Estudio transversal y analítico en universitarios de primer año de la Pontificia Universidad Católica de Chile (PUC). Se realizó una encuesta vía online obteniendo información demográfica y caracterización de dietas de aquellos que se consideraban vegetarianos. Las variables fueron analizadas mediante el software IDM SPSS Statistics® y en planilla Excel® de forma cuantitativa. RESULTADOS: 152 alumnos respondieron la encuesta (15,2% del total), siendo el 49,4% de estos vegetariano. El 32,4% inició este patrón alimentario entre los 12-18 años; sus motivaciones más frecuentes fueron las medio ambientalistas (91,9%) y animalistas (72,9%). El 52,9% de los vegetarianos reciben suplementación de vitamina b 12 pero solo un 15,9% reportó presentar este déficit. El 75,7% obtiene información relacionada acerca de las dietas vegetarianas a través de medios digitales. CONCLUSIÓN: Se encontró un alto porcentaje de estudiantes vegetarianos en las encuestas contestadas, lo que hace necesario que los profesionales de salud estén capacitados en esta área para asegurar una adecuada educación nutricional, suplementación si es necesario, y seguimiento.

INTRODUCTION: There has been an increase in the popularity of vegetarian diets, especially among adolescents and young adults. These diets seem to be healthy and balanced, but the recommendations are contro versial regarding potential nutritional deficits. OBJECTIVE: To identify the frequency and types of ve getarian diet used, their motivation, and sources of information. PATIENTS AND METHOD: Cross-sec tional analytical study in freshmen students from the Pontifical Catholic University of Chile (PUC). Through an online survey, we collected demographic information and diet characterization of those who considered themselves as vegetarians. Variables were analyzed using IDM SPSS Statistics® soft ware and in Excel® spreadsheet in a quantitative way. RESULTS: 152 students answered the survey (15.2% of the sample) and, out of these, 49.4% were vegetarian. 32.4% started this eating pattern bet ween the ages 12 and 18 and among their most frequent motivations were environmentalists (91.9%) and animalists (72.9%). 52.9% of vegetarians take vitamin B 12 supplementation but only 15.9% reported having this deficiency. 75.7% obtain information related to vegetarian diets through digital media. CONCLUSION: In the surveys answered, we found a high percentage of vegetarian students, the refore, health professionals need to be trained in this area to assure adequate nutritional education, supplementation if necessary, and follow-up.

Trends and Predictors of Oral Anticoagulation in Patients with Atrial Fibrillation: A Serial Cross-Sectional Study from 2011 to 2016

Abstract Background: Despite the efficacy of vitamin K antagonists against stroke in patients with atrial fibrillation (AF), the underuse of this therapy is well documented. Objectives: To evaluate trends and predictors of oral anticoagulants utilization in patients with AF. Methods: Observational, retrospective, serial cross-sectional study between 2011-2016. Comparisons between groups were performed using the Student t, Mann-Whitney and Chi-square tests. Logistic regression was used to identify independent predictors of anticoagulation. A p value < 0.05 was considered significant. Results: A total of 377 patients were analyzed. The mean age was 70 ± 15 years; 52% were male and 75% were anticoagulated (20% with VKA and 55% with DOAC). Over 5 years, the overall frequency of anticoagulation increased by 22.4%. The use of DOACs increased from 29% to 70%, whereas the use of VKA decreased from 36% to 17%. The use of antiplatelet agents alone also fell from 21% to 6%. The predictors of anticoagulation were previous episodes of AF (OR 3.1, p < 0.001), hypertension (OR 3.0, p < 0.001) and HASBLED score (OR 0.5, p < 0.001). The predictors of DOAC use were serum creatinine (OR 0.2, p = 0.002), left atrial size (OR 0.9, p = 0.003) and biological valve prosthesis (OR 0.1, p = 0.007). Of the 208 patients using DOACs, 63 (30%) received inadequate prescriptions: 5 with severe drug interactions and 58 with incorrect dosing. Conclusions: Between 2011 and 2016, DOACs were rapidly incorporated into clinical practice, replacing AVKs and antiplatelets, and contributing to greater use of anticoagulation in patients with AF.

Relationship between anthropometric nutritional status and functional capacity in older adults living in the community / Relación entre estado nutricional antropométrico y condición física funcional en adultos mayores independientes

ABSTRACT Background: The functional fitness of older people may be associated with their nutritional status. Aim: To assess the association between of anthropometric measures with functional fitness in older people. Material and Methods: Cross-sectional study conducted in 75 participants aged 65 to 89 years. Body mass index (BMI), waist-to-height ratio (WHtR), fat mass (FM) and skeletal muscle mass index (SMI) were calculated from anthropometric measures. The functional fitness was determined using the Senior Fitness Test battery. Results: BMI and FM indicated obesity, and WHtR indicated cardiometabolic risk in 49%, 55% and 83% of participants, respectively. SMI indicated a low muscle mass in 91% of females. Performance standards of chair stand, arm curl, 2-min step test and 8-foot up-and-go tests were met in 1%, 8%, 1% and 89% of participants, respectively. Significant negative correlations were found between 2-min step test and BMI, WHtR and FM (r = −0.26, −0.31 and −0.48 respectively). Back scratch had a negative correlation with BMI (r = −0.23) and SMI (rho = −0.28). Significant positive correlations were found between 8-foot up-and-go, WHtR (rho = 0.28) and FM (rho = 0.23), and between 2-min step test and SMI (rho = 0.28). The coefficient of determination (R2) between 2-min step test with BMI, WHtR and FM were 0.05, 0.08 and 0.22, respectively, while the R2 between back scratch and BMI was 0.04. Multiple regression models indicated that FM affected the 2-min step test independently of BMI and WHtR (adjusted R2 = 0.22), however age and sex negatively influenced these associations. Conclusions: Functional fitness of older adults is influenced by nutritional anthropometric measures, particularly BMI, WHtR and FM for aerobic capacity, and BMI for upper limb flexibility.

Introducción: El estado nutricional y la condición física funcional (CFF) pueden estar relacionados en adultos mayores. Objetivo: Analizar la influencia de medidas antropométricas nutricionales sobre CFF. Material y Método: Estudio transversal realizado en 75 adultos de 65 a 89 años. Las variables antropométricas fueron índice de masa corporal (IMC), razón cintura-talla (RCT), masa adiposa (MA) e índice de masa muscular esquelética (IMME). La evaluación de CFF se efectuó con la batería Senior Fitness Test. Resultados: El IMC y MA indicaron obesidad, y RCT indicó riesgo cardiometabólico en 49%, 55% y 83% de los participantes, respectivamente. IMME indicó una baja masa muscular en 91% de las mujeres. El estándar de rendimiento para las pruebas sentarse-levantarse, flexión-codo, paso-2-minutos y levantarse-caminar-sentarse se logró en 1%, 8%, 1% y 89% de los participantes, respectivamente. Se encontraron correlaciones significativas negativas entre paso-2-minutos con IMC, RCT y MA (r = −0.26,-0.31 y-0.48 respectivamente. La misma asociación se observó entre juntar-manos-espalda con IMC (r = −0.23) e IMME (rho = −0.28). Se encontraron correlaciones significativas positivas entre levantarse-caminar-sentarse con RCT (rho=0.28) y MA (rho = 0.23), y entre paso-2-minutos con IMME (rho = 0.28). Los R2 entre paso-2-minutos e IMC, RCT y MA fueron 0.05, 0.08 y 0.22, respectivamente, mientras que el R2 entre juntar-manos-espalda e IMC fue 0.04. Los modelos de regresión múltiple indicaron que MA afectó la prueba paso-2-minutos independientemente de IMC y RCT (R2 ajustado = 0.22), aunque la edad y sexo afectaron negativamente estas asociaciones. Conclusiones: La CFF de adultos mayores es influenciada por alteraciones evidenciadas por medidas antropométricas nutricionales, particularmente IMC, RCT y MA sobre la capacidad aeróbica, e IMC sobre la flexibilidad de extremidad superior.

Access to rrimary health care by older adults from rural areas in Southern Brazil / Acesso à atenção primária à saúde por idosos residentes em zona rural no Sul do Brasil

ABSTRACT OBJECTIVE To characterize the access and use of health services considered reference among the older rural population from a municipality in southern Brazil, whose rural area has full coverage of the Family Health Strategy (FHS), investigating factors associated with the choice of the Basic Family Health Unit (BFHU) as reference. METHODS This is a cross-sectional study conducted in 2017 with systematic sampling of rural households in the municipality of Rio Grande (RS) using a standardized in-house questionnaire. We performed descriptive analyses of sociodemographic profile, type of reference service chosen, and reasons for choosing/using the prime-choice service and the nearest BFHU. Poisson regression was used to investigate factors associated with the type of reference service chosen. RESULTS Among the 1,030 older adults who participated in the study, 61.4% considered the BFHU a prime choice/reference service mostly due to its proximity (82.6%); the others sought other places due to a greater ease (34.6%) and resoluteness (52.6%). Almost ⅔ of the respondents sought care at the BFHU during the last year, and the reasons differed among those who considered the unit as reference (chronic disease) and those who sought another place (procedures). We also found that the lower the age, income, education, and household-unit distance, the greater the likelihood of the older adult considering the nearest BFHU as reference service. CONCLUSIONS The FHS has reached the vulnerable older rural population, approaching an equitable public health system. However, further evaluations are necessary to verify the quality and adequacy of care, given that social structure, enabling factors (such as economic condition), and possible beliefs regarding health still establish the standards for choosing a service.

RESUMO OBJETIVO Caracterizar o acesso e utilização de serviços de saúde considerados como referência pela população rural idosa de um município do sul do Brasil, com cobertura de 100% da área rural pela Estratégia Saúde da Família (ESF), investigando os fatores associados à escolha da Unidade Básica de Saúde da Família (UBSF) como serviço de referência. MÉTODOS Estudo transversal com amostragem sistemática dos domicílios da área rural do município de Rio Grande (RS), realizado em 2017, através de questionário padronizado, aplicado em domicílio. Foram realizadas análises descritivas referentes a perfil sociodemográfico; tipo de serviço de referência escolhido; e motivos de escolha/utilização do serviço de primeira opção e da UBSF mais próxima. Realizou-se regressão de Poisson para investigar fatores associados ao tipo de serviço de referência escolhido. RESULTADOS Participaram do estudo 1.030 idosos, dos quais 61,4% indicaram a unidade básica como serviço de primeira opção/referência. Enquanto aqueles que escolheram ser atendidos na UBSF o faziam principalmente em razão da proximidade (82,6%), os demais procuraram outros locais pela percepção de maior facilidade (34,6%) e resolutividade (52,6%). Quase ⅔ dos entrevistados buscaram atendimento na UBSF no último ano, e os motivos foram diferentes entre aqueles que consideravam a unidade como referência (doença crônica) e aqueles que procuravam outro local (procedimentos). Além disso, quanto menor a idade, renda, escolaridade e distância residência-unidade, maior a probabilidade do idoso considerar a UBSF mais próxima como serviço de referência. CONCLUSÃO A ESF tem conseguido atingir a parcela rural idosa em situação de vulnerabilidade, indo ao encontro de um sistema de saúde público equitativo. Todavia, novas avaliações para averiguar adequação e qualidade do atendimento se fazem necessárias, visto que estrutura social, fatores capacitantes (como condição econômica) e possíveis crenças sobre saúde ainda definem o padrão de escolha do serviço.

Avaliação do vocabulário em crianças brasileiras: revisão sistemática de estudos com três instrumentos / Vocabulary assessment in Brazilian children: a systematic review with three instruments

RESUMO Objetivo: investigar, por meio de revisão sistemática, como três instrumentos de avaliação do vocabulário infantil (Teste de Linguagem Infantil ABFW, Expressive Vocabulary Test - EVT - e Peabody Picture Vocabulary Test - PPVT) têm sido utilizados nas pesquisas brasileiras, verificando seus propósitos de usos e os principais resultados encontrados. Estratégia de pesquisa: a revisão foi organizada em dois estudos. O Estudo 1 referiu-se ao procedimento de busca a priori, e o Estudo 2, ao procedimento de busca a posteriori. Foram consultadas três bases de dados nacionais (CAPES, SciELO e PePSIC). Critérios de seleção: para o Estudo 1, foram selecionados artigos empíricos contendo resultados de pesquisas em um dos testes de interesse, em amostra de crianças com desenvolvimento típico em idade escolar (7-10 anos). Para o Estudo 2, foi ampliada a busca para crianças em idade pré-escolar e com algum tipo de transtorno do desenvolvimento. Análise dos dados: os artigos selecionados foram lidos na íntegra e sintetizados em uma tabela contendo objetivo do estudo, faixa etária da amostra, instrumento, delineamento, principais resultados e periódico de publicação. Resultados: foram encontrados 24 estudos, a maioria na área da Fonoaudiologia. Os resultados indicam predominância de pesquisas transversais e observacionais, que buscaram traçar perfil cognitivo de crianças com algum transtorno do desenvolvimento, utilizando ou não grupos de controle. Nenhuma pesquisa tratou da investigação psicométrica dos instrumentos. Conclusão: mostra-se necessária a condução de pesquisas no Brasil que enfoquem na investigação psicométrica de instrumentos de avaliação do vocabulário em crianças pré-escolares e em idade escolar.

ABSTRACT Purpose: To investigate, through a systematic review, how three assessment instruments for children's vocabulary (Test of Childhood language ABFW, Expressive Vocabulary Test - EVT, and Peabody Picture Vocabulary Test - PPVT) have been used in Brazilian research, verifying its purposes of uses and the main results of the researches. Research strategy: This review was organized in three studies. Study 1 referred to the process of a priori search and Study 2 referred to the a posteriori search. We searched for three Brazilian's database (CAPES, SciELO, and PePSIC). Selection criteria: For Study 1, we selected empirical studies containing research data with one of the three-targeted tests, using typically developing school children (7 to 10 years old). For Study 2, we enlarged the age range for pre-school and extended the search to non-typically developing children. Data analysis: The selected articles were fully read and synthesized in a table containing the study's aims, the age range of the sample, instrument, research design, main results, and journal. Results: We found out 24 articles, most of which from the speech-language therapy area. The results indicated the predominance of cross-sectional and observational studies, aiming to delineate the cognitive profile of children with some developmental disturbance, with or without control groups. None of the researches conducted a psychometric inquiry of the instruments. Conclusion: In Brazil, it is necessary to carry out research focusing on the psychometric inquiry of instruments for evaluating the vocabulary in pre-school and school-age children.

INTRODUCCIÓN No existen reportes sobre el índice de burnout en traumatólogos que ejercen en Chile. OBJETIVO Evaluar la presencia de burnout y otros aspectos de calidad de vida en esa población. MATERIAL Y MÉTODO Estudio transversal analítico. Encuesta diseñada para conocer el auto-reporte de burnout y síntomas depresivos entre otros factores. Se incluyeron variables demográficas, laborales, sociales, hábitos personales y anímicas. La encuesta fue compartida vía online a miembros de la Sociedad Chilena de Ortopedia y Traumatología. Se realizó análisis estadístico para buscar asociación entre variables, utilizando pruebas de Chi-cuadrado, test exacto de Fisher y regresión logística (p < 0,05). RESULTADOS Encuesta respondida por 136 especialistas. Rango etario modal menor de 40 años (46,3%), 94,1% hombres. Un 53,7% reportó burnout más de una vez al año, 11% anhedonia, 9,6% ánimo depresivo más de la mitad del mes o casi todos los días y 59,6% cansancio diario. Se encontró asociación significativa entre burnout y edad menor de 40 años (p = 0,004), ausencia de hijos (p = 0,007), dieta no saludable (p = 0,001), anhedonia (p = 0,007), temor a demandas (p < 0,001) y cansancio (p < 0,003). CONCLUSIÓN Más de la mitad de los traumatólogos encuestados reportaron burnout más de una vez al año y cerca del 10% presentan síntomas depresivos semanalmente. Una edad menor a 40 años, anhedonia, el temor a demandas laborales y el cansancio al final de la jornada, fueron las variables de mayor impacto en la manifestación del burnout. La presencia de hijos y una dieta saludable fueron factores protectores.

INTRODUCTION There are no reports regarding the burnout index in Orthopaedic Surgeons in Chile. OBJECTIVE Assess the presence of burnout and other life quality aspects of this population. MATERIAL AND METHODS Cross-Sectional analytical study. An originally designed survey was used to identify the self-report on burnout and depressive symptoms, amongst other factors. Demographic, work-related, social, personal habits, and mood-related variables were included. The survey was distributed by email to members of the Chilean Orthopaedic Surgery Society. Statistical analysis was conducted to determine the association between variables through the Chi-square test, Fisher's exact test, and logistic regressions (p < 0.05). RESULTS The survey was answered by 136 orthopaedic surgeons. The modal age range was less than 40 years (46.3%), and 94.1% were men. Of those surveyed, 53.7% reported a burnout episode more than once per year, 11% anhedonia, 9.6% a depressive mood more than half of the month or almost every day, and 59.6% of chronic fatigue. Statistical analysis showed a significant association between burnout and age under 40 years old (p = 0.004), not having children (p = 0.007), a non-healthy diet (p = 0.001), anhedonia (p = 0.007), fear of lawsuits (p < 0.001) and fatigue (p < 0.003). CONCLUSION More than half of the surveyed orthopaedic surgeons reported episodes of burnout more than once per year, and near 10% referred to have experienced weekly depressive symptoms. Age under 40 years, anhedonia, fear of lawsuits, and fatigue were the variables of more significant impact over the self-report of burnout. Having children and a healthy diet resulted in protective factors.

Abstract Objective To define the major epidemiological features of upper limb penetrating injuries, as well as to identify the causes and the frequency of these lesions at the Instituto de Ortopedia e Traumatologia, a hand surgery center in the city of São Paulo, state of São Paulo, Brazil. Methods The present study was based on a sample of consecutive patients from our orthopedics and traumatology institute from May 2014 to May 2016. Data were collected by telephone, and a prestructured questionnaire regarding data and features of the lesions was applied. Descriptive statistics and proportions comparison with the chi-squared test were performed with a p-value < 5% considered as statistically significant. Results At first, 1,648 records were considered and, after applying the exclusion criteria and eliminating duplicate records, 598 records were included in the present study. Most of the patients weremale (77.8%), right-handed (95.82%), with an average age of 37.27 years old.Manual laborers were the most injured individuals (50.00%), and fingers were the most affected site (51.84%). Glass was the most frequent etiologic agent (33.77%). The prevalence of amputation was higher in industrial machinery injuries (p < 0.05) when compared with other causes. Younger patients (< 18 years old) had more glass-related injuries, while older patients ( 60 years old) had more traumas caused by power tools (p < 0.05). Women had more injuries resulting from razors and glass (p < 0.05). Manual laborers had a higher frequency of power tools and industrial machinery-related injuries (p < 0.05) and a higher prevalence of amputations (p < 0.05). Conclusion Themost frequent etiology was glass, especially in individuals < 18 years old.Women and older patients (> 60 years old) presented a high frequency of traumas caused by razors and power tools, respectively. More severe injuries were caused by machinery and were related with work activity.

Instabilidade postural e a condição de fragilidade física em idosos / Postural instability and the condition of physical frailty in the elderly / Inestabilidad postural y la condición de fragilidad física en adultos mayores

Objetivo: analisar a relação entre instabilidade postural e a condição e os marcadores de fragilidade física de idosos em assistência ambulatorial de geriatria e gerontologia. Método: estudo transversal com amostra constituída por 381 idosos. A fragilidade física foi avaliada mediante o fenótipo de fragilidade e a instabilidade postural pela Escala de Equilíbrio de Berg. Realizaram-se análises univariadas pelo teste Qui-quadrado e multivariadas pelo Forward Stepwise, que resultou no modelo de fragilidade física associado à instabilidade postural. Resultados: dos participantes, 56 (14,7%) eram frágeis, 217 (57%) pré-frágeis e 68 (28,3%) não frágeis. Associaram-se à instabilidade postural a pré-fragilidade (p<0,001), fragilidade (p=0,000) e os marcadores força de preensão manual (p=0,0008), perda de peso não intencional (p=0,0094), nível de atividade física (p=0,0001), fadiga/exaustão (p<0,0001) e velocidade da marcha (p<0,0001). Conclusão: a presença de instabilidade postural determina maior chance do idoso ser frágil ou pré-frágil. Esse resultado favorece o planejamento dos cuidados gerontológicos de enfermagem e fortalece o plano de tratamento sob uma abordagem específica.

Objective: to analyze the relationship between postural instability and the condition and markers of physical frailty of the elderly people in outpatient geriatric and gerontology care. Method: a cross-sectional study with a sample of 381 elderly subjects. Physical frailty was evaluated by the frailty phenotype and postural instability through the Berg Balance Scale. Univariate analyses consisted in Chi-square tests, and multivariate analyses used the Forward Stepwise method, which resulted in a model of physical frailty associated with postural instability. Results: among the participants, 56 (14.7%) were frail, 217 (57%) pre-frail, and 68 (28.3%) non-frail. Pre-frailty (p < 0.001), frailty (p = 0.000), and the markers hand grip strength (p = 0.0008), unintentional weight loss (p = 0.0094), level of physical activity (p = 0.0001), fatigue/exhaustion (p = 0.0001), and gait speed (p = 0.0001) were associated with postural instability. Conclusion: the presence of postural instability determines a greater chance of the elderly being frail or pre-frail. This result favors the planning of gerontological nursing care and strengthens the treatment plan under a specific approach.

Ese resultado favorece la planificación de los cuidados gerontológicos de enfermería y fortalece el plan de tratamiento bajo un abordaje específico.

Drug interactions in maternal intensive care: prevalence, risk factors, and potential risk medications / Interações medicamentosas em terapia intensiva materna: prevalência, fatores e medicamentos de risco

ABSTRACT Objective: To characterize severe potential drug interactions in maternal intensive care, and to determine their frequency, risk factors and potential risk medications. Methods: An observational and longitudinal study conducted between December 2014 and December 2015 in a maternal intensive care unit. Clinical data were collected and severe potential drug interactions were identified on pregnant inpatients. The drug interactions were classified by type, prevalence and exposure rate. A multivariate logistic regression model was used to identify the severe potential drug interactions and the related drugs (p<0.05). Results: A total of 95.1% of patients were exposed to, at least, one potential drug interaction; in that, 91.7% 33.9% were related to, respectively, moderate and severe potential drug interactions. The patients were exposed, on average, on 69.2% of days they were in the intensive care unit. The main drugs involved in more severe drug interactions were magnesium sulfate, metoclopramide, propranolol and diazepam. Conclusion: The severe potential drug interactions were observed in almost all patients of the study, and, approximately one third of those interactions were related to greater severity and resulted in exposure during long hospital stay. The higher number of prescribed drugs and its previous use of medications at home increase the occurrence of severe potential drug interactions.

RESUMO Objetivo: Caracterizar as interações medicamentosas potenciais graves em terapia intensiva materna, e determinar sua frequência, os fatores e os medicamentos de risco associados à ocorrência dessas interações. Métodos: Estudo observacional e longitudinal executado entre dezembro de 2014 a dezembro de 2015, conduzido em uma unidade de terapia intensiva materna. Foram coletados dados clínicos e identificadas interações medicamentosas potenciais graves de gestantes admitidas. As interações medicamentosas foram caracterizadas quanto ao tipo, à prevalência e à taxa de exposição. Um modelo multivariado de regressão logística foi utilizado para identificação de fatores associados à ocorrência de interações medicamentosas potenciais graves e os medicamentos implicados (p<0,05). Resultados: Um total de 95,1% das pacientes foi exposto a, no mínimo, uma interação medicamentosa potencial, com 91,7% delas envolvidas com interações medicamentosas potenciais moderadas e 33,9% com as interações graves. As pacientes ficaram expostas, em média, em 69,2% dos dias que estiveram sob terapia intensiva. Os principais medicamentos implicados em interações medicamentosas de maior gravidade foram sulfato de magnésio, metoclopramida, propranolol e diazepam. Conclusão: As interações medicamentosas potenciais graves ocorreram na maioria das pacientes avaliadas. Aproximadamente um terço das interações foram graves e levaram à maior exposição por um longo período de internação. Maior número de fármacos prescritos e uso prévio domiciliar de medicamentos elevam a ocorrência de interações medicamentosas potenciais graves.

Association between self-efficacy and sociodemographic and clinical variables in patients with Diabetes Mellitus / Associação entre autoeficácia e variáveis sociodemográficas e clínicas em pacientes com Diabetes Mellitus

Model of study: A cross-sectional study was conducted. Objective: to evaluate the association between self-efficacy and socio-demographic and clinical variables in patients with type 2 diabetes mellitus (T2DM). Method: The sample was composed by 111 patients with T2DM in use of insulin, in primary health care units and outpatient setting in the southeast region of São Paulo state, Brazil. Sociodemographic data were gathered using validated questionnaire and clinical data were obtained from medical and health records. Self-efficacy was assessed by the Brazilian version of Insulin Management Diabetes Self-Efficacy Scale (IMDSES). The data were submitted to descriptive and comparative analyses using Mann-Whitney and Kruskal-Wallis to verify association between socio-demographic/clinical variables and self-efficacy. Results: Self-efficacy was associated with schooling level and presence of comorbidities, such as coronary artery disease, dyslipidemia, obesity, peripheral arterial disease and peripheral neuropathy. Conclusion: The findings provide support to the design some specifics interventions aimed at improving the selfefficacy of patients with T2DM on insulin use. (AU)

Curative procedures of oral health and structural characteristics of primary dental care

ABSTRACT OBJECTIVE To evaluate if the provision of clinical dental care, by means of the main curative procedures recommended in Primary Health Care, is associated with team structural characteristics, considering the presence of a minimum set of equipment, instrument, and supplies in Brazil's primary health care services. METHODS A cross-sectional exploratory study based on data collected from 18,114 primary healthcare services with dental health teams in Brazil, in 2014. The outcome was created from the confirmation of five clinical procedures performed by the dentist, accounting for the presence of minimum equipment, instrument, and supplies to carry them out. Covariables were related to structural characteristics. Poisson regression with robust variance was used to obtain crude and adjusted prevalence ratios, with 95% confidence intervals. RESULTS A total of 1,190 (6.5%) dental health teams did not present the minimum equipment to provide clinical dental care and only 2,498 (14.8%) had all the instrument and supplies needed and provided the five curative procedures assessed. There was a positive association between the outcome and the composition of dental health teams, higher workload, performing analysis of health condition, and monitoring of oral health indicators. Additionally, the dental health teams that planned and programmed oral health actions with the primary care team monthly provided the procedures more frequently. Dentists with better employment status, career plans, graduation in public health or those who underwent permanent education activities provided the procedures more frequently. CONCLUSIONS A relevant number of Primary Health Care services did not have the infrastructure to provide clinical dental care. However, better results were found in dental health teams with oral health technicians, with higher workload and that plan their activities, as well as in those that employed dentists with better working relationships, who had dentists with degrees in public health and who underwent permanent education activities.

Medidas acústicas e aerodinâmicas em cantores: comparação entre homens e mulheres / Acoustic and aerodynamic measures in singers: a comparison between genders

RESUMO Objetivo Comparar medidas acústicas e aerodinâmicas da voz em homens e mulheres cantores. Método Trata-se de um estudo transversal, observacional, comparativo, com amostra de conveniência. Participaram do estudo 30 homens e 30 mulheres cantores. Foi realizada avaliação das medidas acústicas (intensidade e frequência fundamental) e aerodinâmicas (tempo de expiração, pressão aérea, fluxo de ar expirado e vozeado, volume expiratório, potência e resistência aerodinâmica, impedância acústica e eficiência aerodinâmica) durante a emissão da sílaba /pá/ em frequência e intensidade habituais, sete vezes consecutivas. Estas emissões permitem a extração de medidas de pressão aérea (obtidas da consoante plosiva /p/ que estima a pressão glótica) e das medidas de fluxo aéreo e acústicas da voz (obtidas da vogal /a/ da sílaba /pá/). Resultados Na comparação de homens e mulheres cantores, as mulheres apresentam maiores valores de frequência fundamental, e não houve diferenças na avaliação de valores das medidas aerodinâmicas entre os gêneros. Conclusão Os valores das medidas aerodinâmicas não se diferenciam entre mulheres e homens cantores.

ABSTRACT Purpose Compare acoustic and aerodynamic voice measures between male and female singers. Methods A cross-sectional, observational, comparative study conducted with a convenience sample. Study participants were 30 male and 30 female singers. Acoustic (vocal intensity and fundamental frequency) and aerodynamic (expiration time, air pressure, expiratory and voice airflow, expiratory volume, aerodynamic power and resistance, acoustic impedance, and aerodynamic efficiency) measures were assessed during emission of the syllable /pá/, at usual frequency and intensity, for seven consecutive times. These emissions enable extraction of air pressure measures (obtained by the plosive consonant /p/, which estimates glottic pressure), as well as of airflow and acoustic voice measures (obtained by the vowel /a/ and the syllable /pá/). Results Women presented higher values of fundamental frequency compared with those of men. No differences were identified in the evaluation of aerodynamic measures between the groups. Conclusion Values of aerodynamic measures do not differ between male and female singers.

OBJETIVO: apresentar a metodologia utilizada na construção dos pesos de pós-estratificação do Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel) 2012 e comparar a tendência de indicadores estimados pelos métodos por célula e rake. MÉTODOS: neste painel de estudos transversais, foram estimadas as prevalências de fumantes, excesso de peso, consumo de frutas, verduras e legumes no período 2006-2012, pelos métodos por célula e rake. RESULTADOS: não houve diferenças nas tendências temporais dos indicadores estimados por ambos métodos; porém, as prevalências de fumantes estimadas pelo método rake foram inferiores àquelas estimadas pelo método por célula, enquanto as prevalências do consumo de frutas, verduras e legumes foram superiores; para o excesso de peso, não houve diferença entre os métodos. CONCLUSÃO: o método rake formeceu maior precisão das estimativas quando comparado ao método por célula, revelando-se mais vantajoso, embora apresente vício de cobertura de cadastro.

OBJETIVO: presentar la metodología utilizada para la construcción de pesos de post-estratificación del Sistema de Vigilancia de Fatores de Riesgo y Proteción para enfermedades Crónicas por Encuesta Telefónica (Vigitel) 2012 y comparar una tendencia de indicadores estimados por métodos de rake y célula. MÉTODOS: en este panel de estudios transversales, estimamos las prevalencias de fumantes, exceso de peso, consumo de frutas, verduras y legumbres, de 2006 a 2012, por métodos célula y rake. RESULTADOS: no hubo diferencias en las tendencias temporales de los indicadores; sin embargo las prevalencias de fumantes estimadas por el método rake fueron inferiores a las estimadas por célula, mientras que las prevalencias de consumo de frutas y legumbres fueron superiores; para el exceso de peso, no hubo diferencia entre los métodos. CONCLUSIÓN: método rake tuvo mayor precisión en las estimaciones cuando comparado con célula, mostrando más ventajas, aunque presenta vicio de cobertura de registro.

OBJECTIVE: to introduce the methodology used to calculate post-stratification weights of the 2012 Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel) and to compare the trends of indicators estimated by cell-by-cell weighting and raking methods. METHODS: in this panel of cross-sectional studies, the prevalences of smokers, overweight, and intake of fruits and vegetables from 2006 to 2012 were estimated using the cell-by-cell weighting and raking methods. RESULTS: there were no differences in time trends of the indicators estimated by both methods, but the prevalence of smokers estimated by the raking method was lower than the estimated by cell-by-cell weighting, whilst the prevalence of fruit and vegetable intake was higher; for overweight, there was no difference between the methods. CONCLUSION: raking method presented higher accuracy of the estimates when compared to cell-by-cell weighting method, proving to be most convenient, although it presents register coverage bias.

Schistosomiasis and hepatopulmonary syndrome: the role of concomitant liver cirrhosis

BACKGROUND Hepatopulmonary syndrome (HPS) is defined as an oxygenation defect induced by intrapulmonary vasodilation in patients with liver disease or portal hypertension. It is investigated in patients with liver cirrhosis and less frequently in those with portal hypertension without liver cirrhosis, as may occur in hepatosplenic schistosomiasis (HSS). OBJECTIVES To investigate the prevalence of HPS in patients with HSS, and to determine whether the occurrence of HPS is influenced by concomitant cirrhosis. METHODS We evaluated patients with HSS with or without concomitant liver cirrhosis. All patients underwent laboratory testing, ultrasound, endoscopy, contrast echocardiography, and arterial blood gas analysis. FINDINGS Of the 121 patients with HSS, 64 were also diagnosed with liver cirrhosis. HPS was diagnosed in 42 patients (35%) and was more frequent among patients with concomitant liver cirrhosis than in those without cirrhosis (42% vs. 26%), but the difference was not significant (p = 0.069). HPS was more common in those with spider naevi, Child-Pugh classes B or C and high model for end stage liver disease (MELD) scores (p < 0.05 each). MAIN CONCLUSIONS The prevalence of HPS was 35% in this study. The occurrence of liver cirrhosis concomitantly with HSS may have influenced the frequency of patients presenting with HPS.

Vigilância epidemiológica da transmissão vertical da sífilis: dados de seis unidades federativas no Brasil / Epidemiological surveillance of vertical transmission of syphilis: data from six federal units in Brazil / Vigilancia epidemiológica de la transmisión vertical de la sífilis: datos de seis unidades federativas de Brasil

RESUMO Objetivo Descrever o perfil epidemiológico dos casos notificados de sífilis em gestantes e sífilis congênita nos estados brasileiros do Amazonas, Ceará, Espírito Santo, Rio de Janeiro e Rio Grande do Sul e no Distrito Federal a partir de dados do Sistema Nacional de Agravos de Notificação (SINAN). Métodos Estudo descritivo incluindo avaliação ecológica e transversal. Foram utilizados dados do SINAN Net. Foram calculadas a taxa de detecção de sífilis em gestantes e a taxa de incidência de sífilis congênita por 1 000 nascidos vivos. Para identificar as gestantes notificadas com sífilis com desfecho de sífilis congênita, as duas bases do SINAN foram relacionadas por meio do software RecLink. Como os dados eram de representatividade regional, as comparações foram feitas entre as unidades da federação, e não com a soma dos casos. Resultados A taxa de detecção de sífilis em gestantes cresceu entre 21% (Amazonas) e 75% (Rio de Janeiro). A incidência de sífilis congênita seguiu o mesmo perfil de incremento, variando de 35,6% no Distrito Federal a 639,9% no Rio Grande do Sul, com redução de 0,7% no Amazonas. A realização de pré-natal nas mulheres com desfecho de sífilis congênita variou de 67,3% no Amazonas a 83,3% no Distrito Federal. Das gestantes com sífilis, 43% tiveram desfecho notificado de sífilis congênita. Nas gestantes com sífilis e desfecho de sífilis congênita, o diagnóstico materno ocorreu durante o pré-natal em 74% e no parto em 18%. Em 8% das mulheres ignorava-se o momento do diagnóstico. Conclusão O incremento nas taxas de detecção de sífilis pode ter resultado do aumento na notificação. O monitoramento constante em gestantes é essencial para a eliminação desses agravos.

ABSTRACT Objective To describe the epidemiological profile of reported cases of syphilis in pregnancy and congenital syphilis in five states (Amazonas, Ceará, Espírito Santo, Rio de Janeiro, and Rio Grande do Sul) and the Federal District using data from the Reportable Disease Information System (SINAN). Method This descriptive study including an ecological and cross-sectional evaluation employed data from SINAN Net. The syphilis detection rate in pregnancy and the congenital syphilis incidence rate per 1 000 live births were calculated. To identify pregnant women with syphilis who had an outcome of congenital syphilis, the two SINAN databases were linked using the RecLink software. Because the data were representative at the state (not national) level, comparisons were made between the units of the federation and not with the sum of cases. Results A growth in the syphilis detection rate in pregnancy was detected, ranging from 21% (Amazonas) to 75% (Rio de Janeiro) during the study period. The incidence of congenital syphilis followed the same trend of growth (ranging from 35.6% in the Federal District to 63.9% in Rio Grande do Sul), except for a 0.7% decline in Amazonas. The proportion of women with an outcome of congenital syphilis who had prenatal care ranged from 67.3% in Amazonas to 83.3% in the Federal District. Of the pregnant women with syphilis, 43% had an outcome of congenital syphilis. In pregnant women with syphilis and an outcome of congenital syphilis, maternal diagnosis was made prenatally in 74% and at delivery in 18%. The moment of diagnosis was ignored in 8% of the women. Conclusion The increase in the syphilis detection rate may have resulted from an increase in the report rate. Ongoing monitoring of pregnant women is essential to eliminate syphilis.

RESUMEN Objetivo Describir el perfil epidemiológico de los casos notificados de sífilis en embarazadas y de sífilis congénita en los estados brasileños de Amazonas, Ceará, Espírito Santo, Rio de Janeiro y Rio Grande do Sul y en el Distrito Federal a partir de datos del Sistema Nacional de Información de Enfermedades de Notificación Obligatoria (SINAN). Métodos Estudio descriptivo que incluye una valoración ecológica y transversal. Se utilizaron datos de la Red SINAN. Se calcularon la tasa de detección de sífilis en embarazadas y la tasa de incidencia de sífilis congénita por 1000 nacidos vivos. Para identificar a las embarazadas notificadas con sífilis que causó sífilis congénita, se relacionaron las dos bases del SINAN por medio del software RecLink. Como los datos eran representativos a nivel regional, las comparaciones se hicieron entre las unidades de la federación y no con la suma de los casos. Resultados La tasa de detección de sífilis en embarazadas aumentó entre 21% (Amazonas) y 75% (Rio de Janeiro). La incidencia de sífilis congénita siguió el mismo perfil de incremento, variando de 35,6% en el Distrito Federal a 63,9% en Rio Grande do Sul, con una reducción de 0,7% en Amazonas. Los controles prenatales en las mujeres que tuvieron hijos con sífilis congénita variaron de 67,3% en Amazonas a 83,3% en el Distrito Federal. De las embarazadas con sífilis, en el 43% de los casos se notificó sífilis congénita. En las embarazadas con sífilis que causó sífilis congénita, el diagnóstico materno fue durante la etapa prenatal en 74% de los casos y en el parto en 18% de los casos. En 8% de las mujeres se desconocía el momento del diagnóstico. Conclusión El incremento de las tasas de detección de sífilis puede haber sido consecuencia de una mayor notificación. Es esencial el seguimiento constante de las mujeres embarazadas para eliminar el aumento de esas enfermedades.

Health technology assessment: the process in Brazil / Evaluación de las tecnologías sanitarias: el proceso vigente en el Brasil / Avaliação de Tecnologias em Saúde: o processo no Brasil

ABSTRACT Objectives To describe, analyze, and compare the opinions of decisionmakers involved in the health technology assessment (HTA) process in Brazil in 2011. Methods A cross-sectional study was conducted using a structured questionnaire to evaluate the opinions of a convenience sample of health care professionals from both the public and private health care systems (HCS). The survey collected demographic data for each respondent along with their input on national regulations. Data analysis included descriptive statistics, including chi-square tests to compare groups. Results Of the 200 completed questionnaires, 65% of the respondents were 31–50 years of age; 36% were HCS managers, 49.3% from the public and 50.7% from the private system. The majority of respondents (85%) considered the time permitted for submission of new technology to be inadequate; 88% also stated that the composition of the evaluation committee needed improvement. Respondents from the private health system more frequently stated that submission times were inappropriate (P = 0.019) and that the deadline for a decision by the committee should be defined (P = 0.021), with a maximum of no more than 180 days / 6 months (P < 0.001). Conclusions Respondents indicated that the HTA process should be improved to meet their expectations. Given that new legislation has been enacted to continuously accept submissions, to make decisions within 180 days, and to expand the committee to represent more stakeholders, most of the respondents concerns have been addressed. This study is valuable as an historical analysis of HTA process improvement. Further surveys are needed to track the new HTA process, its application, and its contribution to health care needs in Brazil.

RESUMEN Objetivos Describir, analizar y comparar las opiniones de los encargados de adoptar las decisiones en el proceso de evaluación de las tecnologías sanitarias llevado adelante en el Brasil durante el 2011. Métodos Se realizó un estudio transversal en el que se administró un cuestionario estructurado para evaluar las opiniones de una muestra de conveniencia de profesionales de la salud tanto del sistema público como del privado. La encuesta recopiló los datos demográficos de cada encuestado junto con su opinión respecto de los reglamentos nacionales. El análisis de los datos incluyó estadísticas descriptivas, como la prueba de la ji al cuadrado para comparar los datos de los distintos grupos. Resultados De los 200 encuestados que respondieron el cuestionario, el 65 % tenía 31–50 años; el 36 % ocupaba algún cargo gerencial en el sistema de salud, el 49,3 % pertenecía al público y el 50,7 % trabajaba en el sistema privado. La mayoría de los encuestados (85 %) consideraron insuficiente el tiempo permitido para presentar las nuevas tecnologías; el 88 % también declaró que debía mejorar la composición del comité de evaluación. Los encuestados del sistema de salud privado declararon con más frecuencia que los tiempos de presentación habían sido inadecuados (P = 0,019) y que era necesario definir un lapso máximo para que el comité tomara su decisión (P = 0,021), el que no debía exceder los 180 días o 6 meses (P < 0,001). Conclusiones Los encuestados indicaron que es preciso mejorar el proceso de evaluación de las tecnologías sanitarias a fin de satisfacer sus expectativas. En vista de que se han aprobado nuevas leyes que habilitan la presentación continua de nuevas tecnologías, que imponen la toma de decisiones al cabo de 180 días y que amplían el comité para que estén representados más interesados directos, se ha abordado la mayoría de las inquietudes manifestadas por los encuestados. Este estudio es valioso como análisis histórico del mejoramiento de los procesos de evaluación de las nuevas tecnologías. Es preciso emprender más encuestas para llevar a cabo un seguimiento del nuevo proceso, su aplicación y su contribución a las necesidades de atención de salud en el Brasil.

RESUMO Objetivos Descrever, analisar e comparar as opiniões dos tomadores de decisão envolvidos com o processo de Avaliação de Tecnologias em Saúde (ATS) em vigor no Brasil, em 2011. Métodos Estudo transversal conduzido através de questionário estruturado para avaliar as opniões de uma amostra de conveniência composta de profissionais de saúde dos sistemas de saúde público e privado. Foram coletados dados demográficos de todos os respondentes junto com suas opiniões sobre as regulamentações nacionais. Resultados Dos 200 questionários completados, 65% dos respondentes tinham entre 31-50 anos de idade; 36% eram gestores do sistema de saúde: 49.3% do sistema público e 50.7% do privado. A maioria dos respondentes (85%) considerou que o tempo permitido para a submissão de novas tecnologias era inadequado; 88% informou que a composição do comitê de avaliação necessitava melhorias. Respondentes do sistema privado de saúde responderam, com mais frequência, que os tempos de submissão eram inadequados (P=0.019) e que o prazo para a decisão pelo comitê deveria ser definido (P=0.021), com um prazo não superior a 180 dias/ 6 meses (P<0.001). Conclusões Respondentes indicaram que o processo de ATS deveria ser melhorado para alcançar suas expectativas. O fato de que uma nova legislação em ATS foi aprovada onde se aceitam submissões de forma contínua, tomada de decisões em até 180 dias, e agregam representantes da sociedade ao comitê de avaliação, demonstra que grande parte das preocupações dos respondentes foi respondida. Este estudo tem seu valor como uma análise histórica da melhoria do processo de ATS no país. Pesquisas adicionais são necessárias para acompanhar o novo processo de ATS, sua aplicação e contribuição às necessidades do sistema de saúde no Brasil.

Estudio transversal de las parasitosis intestinales en poblaciones infantiles de Argentina / Cross-sectional study of intestinal parasitosis in child populations in Argentina

RESUMEN Objetivo Determinar la distribución de las enteroparasitosis en niños de nueve provincias representativas del mosaico de ambientes contrastantes de Argentina. Métodos Estudio descriptivo, observacional y transversal en niños preescolares (de 5 años o menos) y escolares (de 6 a 14 años) de las provincias de Buenos Aires (muestra tomada entre 2005 y 2013), Chubut (2010-2013), Corrientes (2012), Entre Ríos (2010-2012), Formosa (2014), La Pampa (2006), Mendoza (2008-2011), Misiones (2005-2008 y 2013) y Salta (2012-2013). Se procesaron muestras seriadas, fecales y de escobillado anal, mediante técnicas de concentración. Los resultados se analizaron por sexo, intervalo de edad y provincia. Se calcularon la frecuencia de parasitosis (monoparasitosis y parasitosis múltiple), la riqueza de especies y el coeficiente de similitud de Sørensen. Resultados Misiones presentó la mayor frecuencia de niños parasitados y Chubut la menor (82,0% vs. 38,4%; p ˂ 0,01). El número de especies fue mayor en Misiones y Buenos Aires y menor en Chubut y La Pampa. Los varones estuvieron más parasitados que las mujeres solo en Buenos Aires. Las mayores frecuencias se encontraron en los preescolares de Buenos Aires y los escolares de Mendoza y Misiones (p < 0,05). La monoparasitosis fue más frecuente en Chubut (67,9%) y las parasitosis múltiples en Formosa (69,2%). Las especies más frecuentes en la mayoría de las provincias fueron Blastocystis sp. y Enterobius vermicularis. De los geohelmintos, Misiones presentó la mayor frecuencia (23,3%) y Mendoza la menor (0,6%); no se hallaron en Chubut, La Pampa y Salta. Buenos Aires, Formosa y Misiones presentaron una composición de especies similar, al igual que Chubut y La Pampa. Conclusiones Las frecuencias de parasitosis en Argentina responden al complejo mosaico de variabilidad climática y socioeconómica del país y revelan una tendencia descendente de norte a sur y de este a oeste.

ABSTRACT Objective Determine the distribution of intestinal parasitosis in children in nine provinces representative of Argentina’s mosaic of contrasting environments. Methods Descriptive, observational, cross-sectional study of preschool children (5 years old or under) and school-age children (6-14 years) in the provinces of Buenos Aires (sample taken between 2005 and 2013), Chubut (2010-2013), Corrientes (2012), Entre Ríos (2010-2012), Formosa (2014), La Pampa (2006), Mendoza (2008-2011), Misiones (2005-2008 and 2013), and Salta (2012-2013). Serial samples, fecal samples, and anal swabs were processed using concentration techniques. The results were analyzed by sex, age interval, and province. Frequency of parasitosis (monoparasitosis and multiple parasitoses), wealth of species, and Sørensen similarity coefficient were calculated. Results Misiones presented the highest frequency of parasitized children and Chubut the lowest (82.0% vs 38.4%; p < 0.01). The number of species was greatest in Misiones and Buenos Aires and lowest in Chubut and La Pampa. Men were parasitized more than women only in Buenos Aires. The highest frequencies were found in preschool children in Buenos Aires and schoolchildren in Mendoza and Misiones (p < 0.05). Monoparasitosis was most frequent in Chubut (67.9%) and multiple parasitosis in Formosa (69.2%). The most frequent species in the majority of provinces were Blastocystis sp. and Enterobius vermicularis. Misiones presented the highest frequency of soil-transmitted helminthes (23.3%) and Mendoza the lowest (0.6%); none were found in Chubut, La Pampa, or Salta. Buenos Aires, Formosa, and Misiones presented a similar species composition, as did Chubut and La Pampa. Conclusions The frequency of parasitosis in Argentina corresponds to the country’s complex mosaic of climatic and socioeconomic variability and shows a declining trend from north to south and from east to west.

Prevalence of risk factors for noncommunicable diseases in an indigenous community in Santiago Atitlán, Guatemala / Prevalencia de los factores de riesgo de las enfermedades no transmisibles en una comunidad indígena de Santiago Atitlán, Guatemala

ABSTRACT Objective To describe the prevalence of noncommunicable disease (NCD) risk factors and assess knowledge of those risk factors in the indigenous community of Santiago Atitlán in Guatemala, a lower-middle income country. Methods A population-based, cross-sectional study was conducted using a modified version of the World Health Organization’s STEPS protocol. Adults aged 20–65 years were surveyed regarding demographics and NCD risk factors, and the survey was followed by anthropometric and biochemical measurements. Results Out of 501 screened individuals, 350 respondents were enrolled. The mean age was 36.7 years, and 72.3% were women. Over 90% reported earning less than US$ 65 per month. Almost 80% were stunted. Among women, 37.3% were obese and over three-quarters had central obesity. Over three-quarters of the entire group had dyslipidemia and 18.3% had hypertension, but only 3.0% had diabetes. Overall, 36.0% of participants met criteria for metabolic syndrome. There was no significant association between participants’ education and NCD risk factors except for an inverse association with obesity by percent body fat. Conclusions Santiago Atitlán is a rural, indigenous Guatemalan community with high rates of poverty and stunting coexisting alongside high rates of obesity, particularly among women. Additionally, high rates of hypertension and dyslipidemia were found, but a low rate of diabetes mellitus. Knowledge of NCDs and their risk factors was low, suggesting that educational interventions may be a high-yield, low-cost approach to combating NCDs in this community.

RESUMEN Objetivo Describir la prevalencia de los factores de riesgo de las enfermedades no transmisibles (ENT) y evaluar el conocimiento de esos factores de riesgo en la comunidad indígena de Santiago Atitlán en Guatemala, un país de ingresos medianos bajos. Métodos Se realizó un estudio transversal basado en la población usando una versión modificada del protocolo STEPS de mediciones físicas de la Organización Mundial de la Salud. Se realizó una encuesta a adultos de 20 a 65 años de edad con respecto a algunas características demográficas y los factores de riesgo de las ENT; la encuesta fue seguida de mediciones antropométricas y bioquímicas. Resultados De las 501 personas encuestadas, se registraron 350 para el sondeo. La media de edad fue 36,7 años, y 72,3% eran mujeres. Más de 90% informó tener un ingreso inferior a los US$ 65 mensuales. Casi 80% padecía retraso del crecimiento. Entre las mujeres, 37,3% eran obesas y más de tres cuartas partes tenían obesidad central. Más de tres cuartas partes del grupo tenían dislipidemia y 18,3% tenían hipertensión, pero solo 3,0% tenía diabetes. En términos generales, 36,0% de los participantes satisfacía los criterios de síndrome metabólico. No se observó una asociación significativa entre el nivel de escolaridad de los participantes y los factores de riesgo de las ENT, excepto una asociación inversa con la obesidad por porcentaje de tejidos grasos. Conclusiones Santiago Atitlán es una comunidad indígena rural de Guatemala con tasas elevadas de pobreza y retraso del crecimiento, que coexisten con tasas altas de obesidad, en particular en las mujeres. Además, se encontraron tasas elevadas de hipertensión y dislipidemia, pero una tasa baja de diabetes mellitus. Se observó un conocimiento bajo de las ENT y sus factores de riesgo, lo que indica que las intervenciones educativas pueden ser un enfoque de alto rendimiento y bajo costo para combatir las ENT en esta comunidad.
