Comparison of nutritional status and growth curves of children and adolescents in the city of Goiânia, Goiás: cross-sectional study

ABSTRACT BACKGROUND: Nutritional status and growth curves can affect cognitive development, increase the risk of infection, and contribute to the development of chronic diseases. Its etiology is related to food, socioeconomic, and maternal conditions. However, to date, no data on these parameters exist in the state of Goiás, Brazil. OBJECTIVE: To compare the nutritional status and growth curves of children and adolescents in the city of Goiânia, Goiás, Brazil. DESIGN AND SETTING: This was a cross-sectional study. A total of 529 individuals were recruited from a primary health center in the municipality. METHODS: To assess nutritional status, the sample was divided into three categories: 3-4, 5-10, and 11-19 years, with z-score classification considering body mass index for age. The classification of growth curves was performed considering the median height values for age, assuming two references: (a) young Brazilian population and (b) one recommended for international use. The independent sample T-test was used to compare anthropometric variables. RESULTS: The results showed that the classification of eutrophics represents a predominant percentage between both sexes (men: 03-04 = 55.4%; 05-10 = 57.6%; 11-19 = 53.5 % and women: 03-04 = 53.5%; 05-10 = 63.9%; 11-19 = 56.9%), and growth curves showed differences in specific periods in both sexes. CONCLUSIONS: It can be concluded that children and adolescents from the city of Goiânia present as predominance the eutrophic nutritional status, followed by the risk of overweight, underweight, obesity, and malnutrition of both sexes.

Growth charts of Brazilian youngs: 20-years data of 95,000 children and adolescents from "Projeto Esporte Brasil" / Curvas de crescimento de jovens brasileiros: dados de 20 anos com 95.000 crianças e adolescentes do "Projeto Esporte Brasil"

Abstract This article aims to present growth curves for height, weight, and BMI of 95,000 Brazilian youths aged 6 to 17 years, including the five regions of the country, the Amazon region, and indigenous populations, and compare them with the World Health Organization (WHO) growth references. The final sample consisted of 52,729 boys and 42,731 girls from the "Projeto Esporte Brasil" database. Body mass and height information were used to derive the curves. The generalized additive model for location, scale, and shape was employed. In this study, we present smoothed weight-for-age, height-for-age, and BMI-for-age curves for boys and girls. Differences were observed between the results of the Brazilian curves and the WHO growth references. The developed curves will be valuable for professionals in medicine, public health, nutrition, physical education, and other related fields, regarding the assessment of physical growth in Brazilian children and adolescents and monitoring the nutritional status of this population. Additionally, these curves will facilitate the identification of individuals or subgroups at risk of diseases and delayed growth, with a greater focus on specific country-related factors.

Resumo O objetivo do artigo é apresentar curvas de crescimento de altura, peso e IMC de 95.000 jovens brasileiros com idades entre 6 e 17 anos, incluindo as cinco regiões do país, a região da Amazônia e os povos indígenas, e comparar com as referências de crescimento da Organização Mundial da Saúde (OMS). A amostra final foi composta por 52.729 meninos e 42.731 meninas provenientes do banco de dados do "Projeto Esporte Brasil". As informações de massa corporal e estatura foram utilizadas para derivar as curvas. O modelo aditivo generalizado para localização, escala e forma foi usado. neste estudo, apresentamos as curvas suavizadas de peso-idade, altura-idade e IMC-idade para meninos e meninas. Foram observadas diferenças entre os resultados das curvas brasileiras e as referências de crescimento da OMS. As curvas desenvolvidas serão úteis para profissionais da medicina, saúde pública, nutrição, educação física, entre outros, no que diz respeito a avaliação do crescimento físico de crianças e adolescentes brasileiros e para monitorar o estado nutricional desta população. Além disso, essas curvas permitirão a detecção de indivíduos ou subgrupos em risco de doenças e crescimento retardado, com um foco maior em fatores específicos do país.

Are sociodemographic and anthropometric variables effective in screening probable and confirmed sarcopenia in community-dwelling older adults? A cross-sectional study

ABSTRACT BACKGROUND: Screening for probable and confirmed sarcopenia using sociodemographic and anthropometric indicators can be a practical, cheap, and effective strategy to identify and treat older people susceptible to this condition. OBJECTIVES: To identify cutoff points for sociodemographic and anthropometric variables in screening probable and confirmed sarcopenia in community-dwelling older adults. DESIGN AND SETTING: This was a cross-sectional study of community-dwelling older adults in Araranguá, Santa Catarina, Brazil. METHODS: Sociodemographic (age, education) and anthropometric (weight, height, body mass index [BMI], waist circumference [WC], and dominant calf circumference [DCC]) factors were considered as predictors. The outcomes were probable sarcopenia (reduction in muscle strength assessed by time ≥ 15 s in the five-time sit-to-stand test) and confirmed sarcopenia (reduction in strength and muscle mass). Receiver operating characteristic curve analysis was used to analyze the ability to track sociodemographic and anthropometric variables for sarcopenia. RESULTS: In 308 older adults, WC > 91 cm in women and age > 69 years in men were useful in screening for probable sarcopenia. The variables age, weight, BMI, WC, and DCC can be used to screen for sarcopenia in older women and men. CONCLUSION: Sociodemographic and anthropometric variables are simple and accessible tools for sarcopenia screening in older adults.

Bloqueadores do Receptor de Angiotensina Avaliados por Medida de Consultório e Residencial da Pressão Arterial. Estudo TeleMRPA / Angiotensin Receptor Blockers Evaluated by Office and Home Blood Pressure Measurements. TeleHBPM Study

Resumo Fundamento O tratamento adequado e a obtenção das metas na hipertensão arterial são importantes na redução dos desfechos cardiovasculares. Objetivos Descrever os bloqueadores do receptor de angiotensina (BRA) em monoterapia ou combinação dupla e a taxa de controle da hipertensão arterial. Métodos Estudo transversal que avaliou pacientes em uso de BRA entre 2017 e 2020. Foram excluídos aqueles em uso de três ou mais anti-hipertensivos. As variáveis analisadas foram: sexo, idade, índice de massa corporal, medidas válidas da medida residencial da pressão arterial (MRPA); pressão arterial sistólica (PAS) e diastólica (PAD) obtidas pela MRPA e de forma casual; variabilidade pressórica; classe dos anti-hipertensivos e dos BRAs. Foram utilizados testes de t pareado, qui-quadrado e Fisher, além de sobreposição dos intervalos de confiança de 95% com nível de significância de 5% (p < 0,05). Resultados Foram selecionados 17.013 pacientes; destes, 12.813 preencheram os critérios, dos quais 62,1% eram do sexo feminino. O número médio de medidas válidas foi de 23,3 (±2,0), com médias para a PAS de 126,8±15,8 mmHg e 133,5±20,1 mmHg (p < 0,001) e para a PAD de 79,1±9,7 mmHg e 83,6±11,9 mmHg (p < 0,001) pela MRPA e medida casual, respectivamente. Losartana foi o BRA mais utilizado e o que apresentou comportamentos mais elevados da pressão arterial. As combinações de BRA com diuréticos ou com antagonistas de canal de cálcio tiveram menores valores de pressão arterial. Conclusões Losartana foi utilizada em mais da metade dos pacientes, apesar de ser a menos eficiente na redução e no controle da pressão arterial.

Abstract Background Adequate treatment of arterial hypertension and achieving arterial hypertension goals in are important in reducing cardiovascular outcomes. Objectives To describe angiotensin receptor blockers in monotherapy or double combination therapy and the rate of arterial hypertension control. Methods This cross-sectional study evaluated patients who were using angiotensin receptor blockers between 2017 and 2020. Those using three or more antihypertensive drugs were excluded. The analyzed variables included sex, age, body mass index, valid home blood pressure monitoring (HBPM) measurements, casual and HBPM systolic and diastolic blood pressure measurements, blood pressure variability, and antihypertensive and angiotensin receptor blocker class. Paired t, chi-square, and Fisher's exact tests were used, as well as overlapping 95% confidence intervals and a significance level of 5% (p < 0.05). Results Of 17,013 patients, 12,813 met the inclusion criteria, 62.1% of whom were female. The mean number of valid measurements was 23.3 (SD, 2.0). The mean HBPM and casual measurements for systolic blood pressure were 126.8 (SD, 15.8) mmHg and 133.5 (SD, 20.1) mmHg (p <0.001), respectively, while those for diastolic blood pressure were 79.1 (SD, 9.7 mmHg) and 83.6 (SD, 11.9) mmHg (p <0.001), respectively. Losartan was the most common angiotensin receptor blocker and resulted in the highest blood pressure values. Combinations of angiotensin receptor blockers with diuretics or calcium channel antagonists resulted in lower blood pressure values. Conclusions More than half of the patients used losartan, although it was the least efficient drug for reducing and controlling blood pressure.

Relationship between tube voltage kV value for head and neck CT angiography and body weight / 中国基层医药

Objective:To investigate the relationship between tube voltage kV value for head and neck CT angiography and body weight.Methods:A total of 120 patients with suspected vascular disease of the head and neck who underwent CT angiography of the head and neck in Beihai People's Hospital from January 2020 to May 2022 were included in this study. Patients were divided into three groups according to different tube voltages: group A (tube voltage 120 kV, n = 45), group B (tube voltage 100 kV, n = 45) and group C (tube voltage 80 kV, n = 30). Patients in group A were divided into group A1 (< 70 kg, n = 15), group A2 (70-85 kg, n = 15) and group A3 (> 85 kg, n = 15) according to different body weights. Patients in group B were divided into group B1 (< 70 kg, n = 15), group B2 (70-85 kg, n = 15) and group B3 (> 85 kg, n = 15) according to different body weights. Patients in group C were divided into group C1 (< 70 kg, n = 15) and group C2 (70-85 kg, n = 15) according to different body weights. Group C3 was not used. The contrast medium used was Loversol. The CT value, image noise, signal-to-noise ratio, contrast to noise ratio, and effective radiation dose of arterial vessels in each group were measured. The images were subjectively evaluated by two physicians who had senior professional titles using a 5-point rating scale. Results:Subjective score of image quality was all ≥ 3 grade in each group. There was no significant difference in image quality rating between groups A1 and A2 and groups B1, B2, and C1. There was a remarkable difference in image quality rating between groups A3, B3, and C2 and the other groups. There was a significant difference in the CT value of blood vessels at four different levels between groups A1, B1 and C1 ( F = 76.82, 64.62, 98.79, 71.85, all P < 0.001). There was a significant difference in CT value of blood vessels at four different levels between groups A2, B2 and C2 ( F = 159.82, 112.33, 108.22, 135.18, all P < 0.001). There was a significant difference in CT value of blood vessels at four different levels between groups A3 and B3 ( t = 4.40, 4.27, 3.91, 3.59, all P < 0.05). In groups B3 and C2, the image noise was remarkably increased, signal to noise ratio and contrast to noise ratio were remarkably decreased compared with those in the other groups. The effective radiation dose of arterial vessels in group B1 was 47% lower than that in group A1 and the effective radiation dose of arterial vessels in group C1 was 73% lower than that in group A1 ( F = 116.18, P < 0.001). The effective radiation dose of arterial vessels in group B2 was 49% lower than that in group A2, and the effective radiation dose of arterial vessels in group C2 was 66% lower than that in group A2 ( H = 35.40, P < 0.001). The effective radiation dose in group B3 was 35% lower than that in group A3 ( t = 3.59, P < 0.05). Conclusion:In CT angiography of the head and neck, the selection of tube voltage kV value is related to body weight. Tube voltage 80 kV is suitable for patients with a body weight < 70 kg, tube voltage 100 kV for patients with a body weight of 70-85 kg, and tube voltage 120 kV for patients with a body weight > 85 kg. These tube voltages can decrease effective radiation dose and ensure image quality, meeting the requirement for clinical diagnosis.

International Society for the Advancement of Kinanthropometry (ISAK) Global: international accreditation scheme of the competent anthropometrist / Sociedade Internacional para o Avanço da Cineantropometria (ISAK) Global: esquema internacional de acreditação do antropometrista competente

Abstract The anthropometric assessment of a person or population is used by professionals from different areas (health, sports, education, ergonomics, engineering), and the quality of the measures obtained by them determines the success of their interventions. This point of view aims to underline the importance of training these professionals through The International Anthropometry Accreditation Scheme (IAAS) implemented by The International Society for the Advancement of Kinanthropometry (ISAK), which aims to create and maintain an international network of professionals updated continuously from the practical and scientific point of view in the anthropometric measurement of excellence. We describe the four-level hierarchical structure of IAAS, which is guided by the rules defined in the ISAK Handbook and the anthropometric procedures described in the ISAK manuals, as well as the importance and functionality of the ISAK website. It is suggested that an ISAK mobile app be developed to, among other things, facilitate communication among its members, streamline data management of accreditation courses and increase the organization's international projection.

Resumo A avaliação antropométrica, de uma pessoa ou população, é utilizada por profissionais de diferentes áreas (saúde, desporto, educação, ergonomia, engenharia), sendo a qualidade das medidas por eles obtida determinante para o sucesso das suas intervenções. O objetivo deste ponto de vista é salientar a importância da formação destes profissionais através do Esquema Internacional de Acreditação em Antropometria/ International Anthropometry Accreditation Scheme (IAAS) implementado pela Sociedade Internacional para o Avanço da Cineantropometria/ International Society for the Advancement of Kinanthropometry (ISAK), entidade que tem o propósito de criar e manter uma rede internacional de profissionais constantemente atualizados do ponto de vista prático e científico na medição antropométrica de excelência. Descrevemos a estrutura hierárquica de quatro níveis do IAAS, que se orienta pelas regras definidas no Handbook ISAK e pelos procedimentos antropométricos descritos nos manuais ISAK, e ainda a importância e funcionalidades do saite da ISAK. Sugere-se o desenvolvimento de um aplicativo móvel da ISAK para, entre outras coisas, facilitar a comunicação entre seus membros, otimizar o gerenciamento de dados dos cursos de acreditação e aumentar a projeção internacional da organização.

Relationship between anthropometric indicators and risk factors for cardiovascular disease in adults and older adults of Rio Branco, Acre / Relação de indicadores antropométricos com fatores de risco para doença cardiovascular em adultos e idosos de Rio Branco, Acre

ABSTRACT OBJECTIVE To analyze the association between anthropometric variables and cardiovascular risk factors in adults and older adults of Rio Branco, Acre. METHODS A population-based cross-sectional study with 641 adults and 957 older adults was conducted. The statistical analyses consisted of the distribution of anthropometric variables according to the cardiovascular risk factors by frequency and dispersion measures. Pearson's correlation coefficient and prevalence ratios (PR) were estimated with their respective 95% confidence intervals (95%CI) using the SPSS ® version 20.0. RESULTS Moderate correlations were obtained in adult men for waist-hip ratio and total cholesterol (r = 0.486; p < 0.001) and for waist-hip and triglyceride ratios (r = 0.484; p < 0.001). The highest prevalence of hypertension and diabetes in adults were observed in men; in the older adults, the prevalence of hypertension was above 65% in both sexes. The prevalence of dyslipidemia was above 78% in obese adults and older adults. When analyzing the associations, a higher strength of association was found between arterial hypertension and waist-to-stature ratio (PR = 13.42; 95%CI 12.58-14.31) and body mass index greater than 30 kg/m 2 (PR = 6.61; 95%CI 6.34-6.89) in adult men. In the analysis of diabetes, the waist-hip ratio presented greater robustness in the association for women (PR = 7.53; 95%CI 6.92-8.20) and men (PR = 9.79; 95%CI 9.14-10.49). CONCLUSION Anthropometric variables are important predictors of cardiovascular risk; however, their assessments should be performed independently, according to sex and age group.

RESUMO OBJETIVO Analisar a associação entre variáveis antropométricas e os fatores de risco cardiovascular na população de adultos e idosos de Rio Branco, Acre. MÉTODOS Estudo transversal de base populacional com 641 adultos e 957 idosos. As análises estatísticas consistiram na distribuição das variáveis antropométricas segundo os fatores de risco cardiovascular por medidas de frequência e dispersão. Foram calculadas a correlação de Pearson e razões de prevalência (RP) com seus respectivos intervalos de confiança de 95% (IC5%), empregando as rotinas do SPSS ® versão 20.0. RESULTADOS Correlações moderadas foram obtidas nos adultos homens para relação cintura-quadril e colesterol total (r = 0,486; p < 0,001) e para relação cintura-quadril e triglicerídeos (r = 0,484; p < 0,001). As maiores prevalências de hipertensão arterial e diabetes nos adultos foram observadas nos homens; já nos idosos, as prevalências de hipertensão ficaram acima de 65% em ambos os sexos. As prevalências de dislipidemia ficaram acima de 78% nos indivíduos obesos adultos e idosos. Ao analisar as associações, constatou-se maior força de associação entre hipertensão arterial e relação cintura-estatura (RP = 13,42; IC95% 12,58-14,31) e com índice de massa corporal maior que 30 kg/m 2 (RP = 6,61; IC95% 6,34-6,89) nos homens adultos. Na análise para diabetes, a relação cintura-quadril apresentou maior robustez na associação para mulheres (RP = 7,53; IC95% 6,92-8,20) e homens (RP = 9,79; IC95% 9,14-10,49). CONCLUSÃO As variáveis antropométricas são importantes preditores de risco cardiovascular; no entanto, suas avaliações devem ser feitas de forma independente, segundo sexo e grupo etário.

Placental measurements and their association with birth weight in a Brazilian cohort / Medidas placentárias e sua associação com o peso ao nascer em uma coorte brasileira

ABSTRACT: Introduction: Epidemiological studies have shown associations between placental measurements and perinatal and later life outcomes. Objectives: To report placental measurements and evaluate their association with birth weight in a Brazilian birth cohort. Methods: Retrospective cohort study with 958 mothers, placentas, and newborns delivered at the Ribeirão Preto Medical School Hospital, Universidade de São Paulo, Brazil, in 2010 and 2011. The information was collected from interviews, medical records, and pathology reports. The placental measurements were: weight, largest and smallest diameters, eccentricity, thickness, shape, area, and birth weight/placental weight and placental weight/birth weight ratios. We analyzed the associations between birth weight and placental measurements using multiple linear regression. Results: Placental weight alone accounted for 48% of birth weight variability (p < 0.001), whereas placental measurements combined (placental weight, largest and smallest diameters, and thickness) were responsible for 50% (p < 0.001). When adjusted for maternal and neonatal characteristics, placental measurements explained 74% of birth weight variability (p < 0.001). Conclusion: Placental measurements are powerful independent predictors of birth weight. Placental weight is the most predictive of them, followed by the smallest diameter.

RESUMO: Introdução: Estudos epidemiológicos demonstraram associações entre medidas placentárias, resultados perinatais e futuros. Objetivos: Descrever medidas placentárias e avaliar suas associações com peso ao nascer numa coorte de nascimentos brasileira. Metodologia: Estudo de coorte retrospectiva de 958 mães, placentas e recém-nascidos no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo, Brasil, em 2010 e 2011. As informações foram coletadas por entrevistas, prontuários médicos e laudos de patologia. As medidas placentárias foram: peso, diâmetros maior e menor, excentricidade, espessura, forma, área, relações peso ao nascer/ peso da placenta e peso da placenta/ peso ao nascer. As associações entre peso ao nascer e medidas placentárias foram examinadas por meio de regressão linear múltipla. Resultados: O peso da placenta foi responsável por 48% da variabilidade do peso ao nascer (p < 0,001), enquanto o conjunto de medidas placentárias (peso, diâmetros maior e menor e espessura) foi responsável por 50% (p < 0,001). Quando ajustadas pelas características maternas e neonatais, as medidas placentárias explicaram 74% da variabilidade do peso ao nascer (p < 0,001). Conclusão: medidas placentárias são preditores independentes do peso ao nascer. O peso placentário é o mais forte preditor dentre elas, seguido pelo diâmetro menor.

Judo performance: kinanthropometric importance for technical tactical and biomechanics / Análise de performance no judô: considerações cineantropométricas e biomecânicas

Abstract In such a competitive combat sport as judo, it is important that the training is carefully planned so that the athlete can stand out in the international competition. In this context, it is important that the trainer and evaluator are accurate regarding the measures taken of the athlete. Such measures, when correctly performed, can prepare the trainer with tools that allow prescribing contextualized training. The present point of view will show how kinanthropometric variables can be considered by coaches and evaluators when performing technical-tactical and biomechanical analysis in judo athletes. There are differences between sex and weight divisions as to the actions that are prevalent in each one of the categories. Lighter divisions performances must have specific training regarding approach and gripping. Attention should be paid to anticipation in athletes of the light and middle divisions. The rating of force development is the most important biomechanical measure.

Resumo Em uma modalidade esportiva de combate tão competitiva como o judô é importante que o treinamento seja planejado minuciosamente para que um atleta possa se destacar no cenário competitivo internacional. Neste contexto, é importante que o treinador e avaliador sejam precisos quanto as medidas realizadas no atleta. Tais medidas, quando corretamente realizadas, podem municiar o treinador com ferramentas que permitam prescrever treinamentos contextualizados. O presente ponto de vista apresentará como variáveis cineantropométricas podem ser consideradas por treinadores e avaliadores ao realizarem análises técnico-táticas e biomecânicas em atletas de judô. Existem diferenças entre sexo e categorias de peso quanto às ações que são predominantes. Categorias mais leves realizam devem realizar treinos específicos quanto ao approach e pegada. Deve-se dedicar atenção a antecipação em atletas das categorias leves e médio. A taxa de desenvolvimento de força é a variável biomecânica mais importante

Nutrition status of the elderly differs by elderly care facility / El estado nutricional en los adultos mayores es diferente de acuerdo con cada tipo de hogar geriátrico

The prevalence of malnutrition in homes for the elderly is well-known, yet research does not exist concerning differences among types of homes. In this study, the association of nutritional status (measured with MNA-FV and anthropometric measures) with the type of home for the elderly (charity, government, private) was evaluated. A cross-sectional study in adults > 60 years was carried out. Students t, U of Mann-Whitney, ANOVA, or Kruskal Wallis test with statistical significance p < 0.05 were used for statistical analysis. In the study, 152 elderly (95 female) persons with an average age of 81.4 years (SD 7.82) participated; 59.6% had a normal nutritional status and 45.3% had a normal BMI. Malnutrition, risk of malnutrition and low calf circumference were associated with private homes (p < 0.05). We concluded that nutritional status varies by type of home and this nutritional profile possibly depends on criteria used to admit persons into each type of facility.

La prevalencia de la malnutrición en los hogares geriátricos es bien conocida, aunque no existen investigaciones sobre las diferencias del estado nutricional entre los tipos de hogares. Se realizó un estudio transversal en adultos > 60 años que evaluó la asociación del estado nutricional (medido con MNA-VL y medidas antropométricas) con el tipo de hogar geriátrico (caridad, gobierno, privado); para el análisis estadístico se utilizó la prueba de t de Student, U de Mann-Whitney, ANOVA o Kruskal Wallis con significación estadística p<0,05. Participaron 152 ancianos (62,5% mujeres) y edad promedio de 81,4 (+/-7,82 años); el 59,6% tenía un estado nutricional normal y el 45,3% tenía un IMC normal. La malnutritión, el riesgo de desnutrición y la baja circunferencia de la pantorrilla (<31cm) se asociaron con hogares privados (p<0,05). Concluimos que el estado nutricional varía según el tipo de hogar y este perfil nutricional posiblemente dependa de los criterios utilizados para admitir a los ancianos en cada hogar.

Stress and Food Consumption Relationship in Hypertensive Patients / Estresse e Consumo Alimentar em Pacientes Hipertensos

Abstract Background: Stress is a state of threat to the balance of the organism, which can cause biological and psychological changes. In hypertensive patients, stress can interfere with blood pressure levels, influence on food choices and neglect of the diet. Objective: This study aims to describe the relationship between stress and dietary intake of hypertensive patients. Methods: A transversal study was carried out at the Arterial Hypertension Clinic of the Cardiology Institute of Rio Grande do Sul, Brazil. The participants were aged ≥ 18 years and hypertensive. Blood pressure, food consumption and anthropometric measurements were collected. The variables related to stress were evaluated by the Lipp's Stress Symptoms Inventory (LSSI) for adults. Significance level of 5% has been considered for all analyzed data. Results: The number of participants was 100. There was a higher prevalence of the female sex (67%), the mean age of the study population was 55.87 ± 12.55 years. Among the participants, 86% were classified in some of the stress phases, on which 57% were in the resistance phase. It was observed that there was no correlation between the presence of stress (as well as their actions), pressure levels and food consumption. The consumption of foods rich in lipids and individuals with a prevalence of psychological symptoms of stress displayed a significant association. Conclusions: Rich in fat dietary has been the first choice in patients with psychological symptoms of stress. Further studies regarding remodeled dietary intake and blood pressure levels in relation to the stress phases are suggested. These findings are important to contribute to the development of prevention and treatment strategies for cardiovascular diseases.

Resumo Fundamento: O estresse é um estado de ameaça ao equilíbrio do organismo, podendo causar alterações biológicas e psicológicas. No paciente hipertenso o estresse pode interferir nos níveis pressóricos e gerar influência nas escolhas alimentares e negligência da dieta. Objetivo: Este estudo tem como objetivo descrever a relação entre o estresse e consumo alimentar de pacientes hipertensos. Métodos: Estudo transversal, desenvolvido no Ambulatório de Hipertensão Arterial do Instituto de Cardiologia do Rio Grande do Sul. Participaram da pesquisa indivíduos hipertensos com idade > 18 anos. Foram coletados dados de pressão arterial, consumo alimentar e medidas antropométricas. As variáveis relacionadas ao estresse foram avaliadas pelo inventário de sintomas de stress para adultos de Lipp (ISSL). Em todas as análises foi considerando um nível de significância 5% (p < 0,05). Resultados: O número de participantes foi de 100. Houve maior prevalência no sexo feminino (67%), a idade média da população estudada foi 55,87 ± 12,55 anos. Dos participantes, 86% se classificaram em alguma das fases do estresse, sendo que destes, 57% estavam na fase de resistência. Observou-se que não houve correlação entre a presença de estresse (bem como suas fases), níveis pressóricos e consumo alimentar. O consumo de alimentos ricos em lipídios em hipertensos com sintomas de estresse apresentou significância estatística. Conclusão: Os alimentos ricos em gordura prevaleceram entre as escolhas alimentares nos pacientes com sintomas psicológicos de estresse. Sugere-se mais estudos em relação a alteração do consumo alimentar e níveis pressóricos em relação às fases do estresse.

Relationship of Age, Body Mass Index, Bone Density, and Menopause Duration with Alveolar Bone Resorption in Postmenopausal Women

Objective: To analyze the relationship between age, body mass index (BMI), bone mineral density (BMD), and alveolar bone resorption with menopause duration in postmenopausal women. Material and Methods: A cross-sectional study was developed involving 59 subjects, aged 45 to 80 years and categorized the duration of menopause as ≤5 years and >5 years. Body mass index measurement and menopause duration were collected. Bone loss seen on radiography was measured by drawing a vertical line from the cementoenamel in the distal part of the 36 teeth and the mesial portion of 46 teeth to the base of the bone marked by the lamina dura intact. Categorical determinations of age, BMI, BMD, and alveolar bone resorption were based on receiver operating characteristic (ROC) curves. Were used Pearson correlation and Spearman correlation tests with the significance level set at 5%. Results: The majority of subjects (54.2%) with menopause duration >5 years were aged >54.5 years, most had BMI >24.2 kg/m2 (39%), had bone resorption >2.95 mm (52.5%), and had bone density ≤73.89 (49.2%). Pearson and Spearman correlation tests showed no significant correlation between age, BMI, bone density, and alveolar bone resorption (p>0.05). Conclusion: The longer the duration of menopause showed a tendency for lower bone density and higher age, BMI, and bone resorption.

Predictive value of obesity measurement index for H-type hypertension / 中国医师杂志

Objective By investigating the obesity of the adult population in Hunan,we explored the relationship between body mass index (BMI) [including waist circumference (WC),waist-to-hip ratio (WHR),waist-to-body ratio (WHtR) and H-type hypertension] in predicting H-type hypertension.Methods A multi-stage random sampling method was used to conduct a questionnaire survey,physical examination and laboratory testing on 4 012 adults ＞ 30 years old in 6 districts of Hunan Province.The receiver operator characteristic (ROC) curve was used to evaluate the predictive effects of BMI,WC,WHR and WHtR on H-type hypertension.Results ROC curve analysis indicated that the area under curve (AUC) of the evaluation of H-type hypertension of WC,WHtR,WHR and BMI in men were:0.637,0.640,0.601,0.639,of which the largest were combination of WC + BMI and WHtR + BMI,both being 0.647.In women,the AUC of individual indexes WC,WHtR,WHR and BMI for evaluating H-type hypertension were 0.660,0.670,0.660 and 0.604 respectively.The combination of WHtR and WHR had the largest AUC,which was 0.675.The WC for evaluating H-type hypertension in youth people had the largest AUC (0.732);the WC + BMI,WHR + BMI for evaluating H-type hypertension in middle-aged people had the largest AUC,all being 0.687;the WC predicted the largest AUC of H-type hypertension in elderly people (0.590).Conclusions WC,WHtR,WHR and BMI are important predictors of H-type hypertension.The optimal indicators for different genders and ages are different,and the combined indicators are better than the individual indicators.

Medidas antropométricas orofaciais em recém-nascidos a termo / Orofacial anthropometric measures in full-term newborns

RESUMO Objetivo Descrever e comparar as medidas antropométricas e as proporções orofaciais de recém-nascidos (RNs) a termo saudáveis, segundo o sexo, de uma maternidade pública do estado de Sergipe, Nordeste do Brasil. Método Estudo randomizado descritivo e analítico. Participaram 46 RNs a termo e saudáveis, de ambos os sexos, selecionados aleatoriamente. Foi utilizado paquímetro digital para tomadas das medidas (em milímetros), com os RNs em posição supina e lábios ocluídos. Quatro pesquisadores foram previamente treinados, com cada RN sendo medido duas vezes por uma mesma dupla destes. Os dados foram descritos por meio de frequências simples e percentuais. As diferenças de média foram avaliadas através do Teste de Mann-Whitney, com significância de 5%. Associações foram avaliadas através do teste Exato de Fisher. Foram calculados tamanhos de efeitos D de Cohen. Resultados Foram obtidas diferenças entre os grupos para as medidas antropométricas: terços da face médio (glabela-subnasal ou g-sn) e inferior (subnasal-gnátio ou sn-gn); e alturas do filtro (subnasal-labial superior ou sn-ls), dos lábios superior (subnasal-estômio ou sn-sto) e inferior (estômio-gnátio ou sto-gn), sempre maiores no sexo masculino. As proporções orofaciais estudadas não apresentaram diferenças entre sexos. Conclusão O estudo apontou presença de disformismo sexual para as medidas da face ao nascimento na população nascida em Aracaju, Sergipe.

ABSTRACT Purpose To describe and compare the anthropometric measurements and the orofacial proportions of healthy term newborns (NB) according to sex, from a public maternity hospital in the state of Sergipe, northeastern Brazil. Methods Descriptive and analytical randomized study was carried out. The participants included were 46 randomly selected healthy and full-term RNs of both sexes. A digital caliper was used to measure measurements (in millimeters) with the NB supine and occluded lips. Twice different, previously trained researchers measured each NB. Data were described using simple and percentage frequencies. The mean differences were assessed using the Mann-Whitney test, with a significance of 5%. Associations evaluated by the Fisher Exact test, and Cohen D size effects were calculated. Results Differences were found between the groups for the anthropometric measurements: midface third height (glabella-subnasal or sn-g) and bottom (subnasal-gnathion or sn-gn); and filter heights (upper-lip subnasal or sn-ls), the upper lips (subnasal-estomus or sn-sto), and lower (stomatal-gnathion or sto-gn), which was always greater in males. The orofacial proportions studied did not show differences between sexes. Conclusion The study showed the presence of sexual dimorphism for the measures of the face at birth in the population born in Aracaju, Sergipe.

Medição das mamas com o Adobe Photoshop® / Breast measurement using Adobe Photoshop®

Introdução: Com a globalização e melhora dos meios digitais e, consequentemente, a crescente utilização de fotografias digitais, faz-se necessária a criação de métodos de mensuração confiáveis. Na prática clínica, a medida direta utilizando-se fita métrica, régua e compasso é mais comumente utilizada. Porém, existem fatores intrínsecos (relevos corporais) e extrínsecos (colaboração do paciente ou movimentos respiratórios) que podem influenciar nos dados obtidos. A fotografia e os softwares gráficos podem ser uma alternativa precisa, mais cômoda e reprodutível à medida direta. O objetivo é demonstrar a forma de medir as mamas pelo software Adobe Photoshop. Métodos: Foram descritas a posição das voluntárias, a captação das imagens, calibração do software até a obtenção mensuração final das mamas. Em 40 mulheres voluntárias, com idade entre 18 e 60 anos, foram demarcados pontos sobre a região mamária e braços em posição frontal. A união destes pontos em cada hemicorpo formou 7 segmentos lineares, 1 angular e 1 segmento mediano comum a ambos os hemicorpos. Essas fotografias foram avaliadas no arquivo RAW, por 3 observadores, com auxílio do software Adobe Photoshop CS6®. Resultados: O Photoshop CS6® demonstrou ser eficaz na mensuração das mamas no arquivo RAW. Conclusão: O Photoshop® apresentou precisão nas medidas e ser factível para mensuração das mamas.

Introduction: With the globalization and improvement of digital media and, consequently, the increasing use of digital photography, it is necessary to create reliable measurement methods. In clinical practice, direct measurement using tape measure, ruler, and compass, is most commonly used. However, there are intrinsic (body contour) and extrinsic (patient collaboration or respiratory movements) factors that may influence the data obtained. Photography and graphics software can be an accurate, comfortable, and reproducible alternative to direct measurement. The objective is to demonstrate how to perform breast measurement using Adobe Photoshop software. Methods: Participants were described the position to assume. Imaging capturing techniques and software calibration were performed in order to obtain the final breast measurement. Markers were placed on the breast and arms of 40 women volunteers aged 18 to 60 years using an anterior view. The union of these markers in each hemibody resulted in seven linear segments, one angle and one transverse segment common to both hemibodies. These photographs were evaluated as a RAW file, by 3 evaluators, assisted by Adobe Photoshop CS6® software. Results: Photoshop CS6® proved effective in the breast measurement using RAW files. Conclusion: Photoshop® showed precision and effectiveness for breast measurement.
