ABSTRACT

Objective: To assess the association between maternal fears about their infant/toddler and depression and anxiety during the COVID-19 pandemic. Methods: In 2019, all mothers who gave birth in hospitals in Rio Grande, RS, Brazil were asked to respond to a standardized questionnaire (baseline). We followed them between May-June 2020 (first follow-up point), August-December 2020 (second follow-up point), and from October 2021 to March 2022 (third follow-up point), and asked them if they were: (1) afraid that their infant/toddler would become infected with COVID or get sick (yes/no), (2) afraid that they would contaminate their own child with COVID, and/or (3) worried about the pandemic's effects on their child's future. At baseline and at all follow-up points, we assessed depressive symptoms using the Edinburgh Postnatal Depression Scale and anxiety symptoms using the Generalized Anxiety Disorder Scale, creating symptom trajectories using group-based trajectory modelling. We used multinomial logistic regression to calculate adjusted relative risk ratios (RRR). Results: A total of 1,296 mothers participated. Worrying about the pandemic's effects on their child's future and the fear of contaminating their own child with COVID-19 increased the risk of raising depressive symptoms to a clinical level (RRR = 4.97, 95%CI 2.32-10.64 and RRR = 3.87, 95%CI 1.58-9.47, respectively) and anxiety to a moderate level (RRR = 2.91, 95%CI 1.69-5.01 and RRR = 1.86, 95%CI 1.03-3.35, respectively). Conclusion: Fear for their children increased maternal depressive and anxiety symptoms during the pandemic.

ABSTRACT

Objective: to evaluate the agreement between measured height, weight, and body mass index (BMI) during the 22-year follow-up of the 1993 Pelotas Birth Cohort, state of Rio Grande do Sul, Brazil, and self-reported data during the online follow-up of the coortesnaweb. Methods: this was a cross-sectional validation study; agreement was assessed by means of Lin's concordance correlation coefficient for continuous measures and weighted Kappa for nutritional status; Spearman's rank correlation coefficient was used to estimate the correlation between measurements. Results: a total of 783 participants were included; it could be seen high correlation and high agreement between the measured height (r = 0.966; ρ = 0.966), weight (r = 0.934; ρ = 0.928), and BMI (r = 0.903; ρ = 0.910) and Web-based self-reported data; there was no correlation between mean difference and the time interval between measurements. Conclusion: using the Internet to collect self-reported anthropometric measurements is as valid as the traditional method.

ABSTRACT

Resumo O Programa Criança Feliz (PCF) atinge 1,4 milhão de crianças brasileiras menores de três anos com visitas domiciliares visando o desenvolvimento neuropsicomotor. Com base em modelo conceitual, avaliou-se implementação e impacto do PCF em estudo randomizado, em 30 municípios. Ao todo 3.242 crianças foram alocadas para o grupo intervenção (GI) ou controle (GC), sendo 80,0% acompanhadas prospectivamente durante três anos. O desenvolvimento foi avaliado pelo Ages and Stages Questionnaire (ASQ3). Análises por intenção de tratar mostraram escores médios de 203,3 no GI e 201,3 no GC. Análises adicionais com variáveis instrumentais e emparelhamento por escores de propensão tampouco mostraram efeito, uma vez que o número de contatos recebidos não esteve associado aos escores ASQ3. Tampouco foi observado impacto sobre estimulação, interações responsivas ou atributos psicológicos das crianças. As visitas foram interrompidas durante 12 meses devido à COVID-19, sendo substituídas por contatos virtuais. O estudo de implementação revelou baixa cobertura no GI, contaminação do GC, deficiências na gestão e baixa qualidade das visitas em muitos municípios. O estudo não demonstrou impacto do PCF implementado sob condições de rotina e fornece elementos para seu aprimoramento.


Abstract The Happy Child Program (Programa Criança Feliz - PCF, in Portuguese) reaches 1.4 million Brazilian children under three years of age with home visits aimed at promoting neuropsychomotor development. Based on a conceptual model, PCF implementation and impact were evaluated in a randomized study in 30 municipalities. A total of 3,242 children were allocated to the intervention (IG) or control (CG) group, 80.0% of whom were prospectively followed up from late 2018 to late 2021. Development was assessed by the Ages and Stages Questionnaire (ASQ3). During the three-year study period, visits were replaced by virtual contacts for an average of 12 months due to COVID-19. At the endline survey, intent-to-treat analyses showed mean scores of 203.3 in the IG and 201.3 in the CG. Additional analyses using instrumental variables and propensity scores matching also showed no effect, since the number of contacts with the program was not associated with ASQ3 scores. No impact was observed on stimulation, responsive interactions or psychological attributes of children. The implementation study revealed low coverage in the IG, contamination of the CG, deficiencies in management and low quality of visits in many municipalities. The study did not demonstrate an impact of PCF implemented under routine conditions, but provides elements for its improvement.

ABSTRACT

Abstract BACKGROUND: Chronically elevated alpha-2-macroglobulin (A2MG) in the blood has been correlated with diabetes and the HbA1c profile; however, no systematic review has been conducted to evaluate the association of A2MG salivary levels and glycemia or HbA1c levels in diabetes mellitus type 2 (DM2) patients. OBJECTIVE: To evaluate whether A2MG salivary levels are related to the glycemia or HbA1c levels in DM2 patients. DESIGN AND SETTING: Systematic review developed at Universidade Federal de Uberlândia (UFU), Brazil. METHODS: Eight databases were used as research sources. The eligibility criteria included studies that reported data regarding mean salivary A2MG and the correlation between glycemia and/or HbA1c levels of DM2 subjects (uncontrolled and well-controlled) and non-diabetic subjects. The risk of bias of the studies selected was assessed using the Joanna Briggs Institute (JBI) critical appraisal tools for use in JBI systematic reviews. Pooled correlation coefficients were estimated using the Hunter-Schmidt method. Study estimates were weighted according to their sample size, and heterogeneity was calculated using the chi-square statistic. RESULTS: Four studies on DM2 patients were included in this systematic review after careful analysis of 1482 studies. Three studies compared A2MG with HbA1c and glycemia. Overall, the correlation between A2MG and HbA1c was strong (r = 0.838). In contrast, the correlation between A2MG and glycemia was low (r = 0.354). CONCLUSION: The strong association between HbA1C and salivary A2MG suggests that this salivary protein has the potential to be a surrogate for HbA1C, if corroboratory further evidence is obtained through large-scale studies.

ABSTRACT

Resumo: O objetivo deste artigo foi avaliar os fatores socioeconômicos, familiares e individuais associados ao desenvolvimento infantil no primeiro ano de vida, entre famílias em vulnerabilidade social. Trata-se de uma análise transversal, com dados da linha de base de um ensaio randomizado. O estudo incluiu 3.242 crianças < 12 meses de idade, residentes em 30 municípios de cinco regiões do Brasil. A escolha de estados e municípios foi intencional, tendo como base a implementação do Programa Criança Feliz. A amostra foi selecionada a partir de crianças elegíveis para o Programa Criança Feliz, cujo objetivo é promover a estimulação e o desenvolvimento infantil. O Ages and Stages Questionnaire (ASQ) foi utilizado para avaliação do desenvolvimento infantil. Um modelo de análise multinível em três níveis (estado, município e indivíduos), usando teste de Wald para heterogeneidade e tendência linear, estimou a média do ASQ-3 e intervalo de 95% de confiança (IC95%). Análises foram ajustadas para potenciais confundidores. Foram analisadas informações de 3.061 (94,4%) crianças com dados disponíveis para ASQ-3. Escores de desenvolvimento infantil (total e em todos os domínios) foram cerca de 12% menores em crianças nascidas pré-termo e com restrição do crescimento intrauterino (pequenas para idade gestacional). Observou-se menores escores em filhos de mães com baixa escolaridade, com sintomas de depressão, com duas ou mais crianças menores de sete anos residindo no domicílio e que não relataram autopercepção de apoio/ajuda durante a gestação. Conclui-se que características potencialmente modificáveis (escolaridade, depressão materna e prematuridade/restrição do crescimento intrauterino) apresentaram maior impacto na redução do escore de desenvolvimento em todos os domínios avaliados.


Abstract: The study aimed to assess socioeconomic, family, and individual factors associated with infant development (i.e., in the first year of life) among families with social vulnerability. This was a cross-sectional analysis of baseline data from a randomized trial. The study included 3,242 children < 12 months of age living in 30 municipalities from five regions of Brazil. The choice of states and municipalities was intentional, based on the implementation of the Brazilian Happy Child Program. The sample was selected among eligible children for the Brazilian Happy Child Program, and the objective was the promotion of infant development. The Ages and Stages Questionnaire (ASQ) was used to assess infant development. A three-level analytical model (state, municipality, and individuals), using the Wald test for heterogeneity and linear trend, estimated the mean ASQ-3 and 95% confidence interval (95%CI). The analyses were adjusted for potential confounders. Information was analyzed for 3,061 (94.4%) children with available data for ASQ-3. Infant development scores (total and in all the domains) were some 12% lower in preterm children and those with intrauterine growth restriction (small for gestational age). Lower scores were seen in children of mothers with low schooling, depressive symptoms, two or more children under seven years of age living in the household, and who did not report self-perceived support or help during the pregnancy. In conclusion, potentially modifiable characteristics (schooling, maternal depression, and prematurity/intrauterine growth restriction) showed greater impact on reducing the infant development score in all the target domains.


Resumen: El objetivo fue evaluar los factores socioeconómicos, familiares e individuales, asociados al desarrollo infantil en el primer año de vida, entre familias con vulnerabilidad social. Se trata de un análisis transversal, con datos de la base de referencia de un ensayo aleatorio. El estudio incluyó a 3.242 niños < 12 meses de edad, residentes en 30 municipios de cinco regiones de Brasil. La elección de estados y municipios fue intencional, considerando como base la implementación del Programa Niño Feliz. La muestra se seleccionó a partir de niños elegibles para el Programa Niño Feliz, cuyo objetivo es promover la estimulación y el desarrollo infantil. Se utilizó el Ages and Stages Questionnaire (ASQ) para la evaluación del desarrollo infantil. Un modelo de análisis multinivel en tres niveles (estado, municipio e individuos), usando el test de Wald para la heterogeneidad y tendencia lineal, estimó la media del ASQ-3 y el intervalo de 95% de confianza (IC95%). Los análisis se ajustaron para potenciales factores de confusión. Se analizó información de 3.061 (94,4%) niños con datos disponibles para ASQ-3. Las puntuaciones de desarrollo infantil (total y en todos los dominios) fueron cerca de un 12% menores en niños nacidos pretérmino y con restricción del crecimiento intrauterino (pequeños para la edad gestacional). Se observaron menores puntuaciones en hijos de madres con baja escolaridad, con síntomas de depresión, con dos o más niños menores de siete años residiendo en el domicilio y que no informaron autopercepción de apoyo/ayuda durante la gestación. Se concluye que las características potencialmente modificables (escolaridad, depresión materna y prematuridad/restricción del crecimiento intrauterino) presentaron un mayor impacto en la reducción de la puntuación de desarrollo en todos los dominios evaluados.

ABSTRACT

Abstract Mucopolysaccharidosis (MPS) is a heterogeneous group of rare, chronic, progressive and systemic inherited disorders resulting from deficiency or lack of lysosomal enzymes responsible for the degradation of glycosaminoglycans. Products of nitrosative stress have been previously detected in blood and urine samples of patients with MPS. However, it is unclear whether they are present in the saliva of MPS patients and also if they correlate with salivary parameters such as flow and pH. This study compared the salivary levels of NOX (NO2- + NO3-), nitrite (NO2-), protein (albumin), erythrocyte and leukocyte numbers, as well as the salivary flow rate and pH values of samples obtained from 10 MPS patients and 10 healthy subjects. MPS patients exhibited higher salivary levels of NOX and NO2- when compared to healthy subjects (p < 0.05). Albumin was only detected in six saliva samples of MPS patients and, erythrocytes and leukocytes were detected in 60% and 40% of the MPS patients, respectively. In addition, salivary flow rate and pH averages were statistically lower in this group when compared to healthy samples (p < 0.05). Overall, the data indicates that the salivary levels of NO products can be used in combination with other heath indicators to monitor MPS disorders.

ABSTRACT

This study aimed to analyze part of the financial resources used to fund public health actions in the 26-Brazilian capitals, from 2008 to 2018. This is a time-trend ecological study involving revenue and expenditure indicators provided by the Information System on Public Budget for Health (SIOPS). The values were deflated based on the Extended National Consumer Price Index of 2018 in Brazil to allow the comparison over the years. The mean annual variation of health investments, in Brazilian Reais (BRL) was assessed using linear regressions. Pearson's correlation coefficients were estimated between federal revenues and expenditures with the capitals' resources. All capitals presented statistically significant positive correlations for the origin of the budget resource invested in health. The lowest coefficient was found in the capital city of Macapá (Amapá State) (r = 0.860) and the highest, in Fortaleza (Ceará State) (r = 0.997). Belo Horizonte (Minas Gerais State) was the capital with the highest annual increase in federal transfers (about BRL 67.91 per year) and Teresina (Piauí State) presented the highest annual increase in health expenditures among the capitals (about BRL 55.42 per year). We found a increase in the transfers of the Brazilian Unified National Health System (SUS) and municipal resources in almost all capitals, but there are still inequalities in the distribution of financial resources among Brazilian capitals from different regions. Health funding is affected by the municipalization of SUS and it is not the single factor affecting the access and quality of health services.


O estudo teve como objetivo analisar parte dos recursos utilizados para financiar ações de saúde pública nas 26 capitais brasileiras entre 2008 e 2018. O estudo ecológico de tendências temporais envolveu indicadores de receitas e gastos fornecidos pelo Sistema de Informação sobre Orçamento Público em Saúde (SIOPS). Os valores foram deflacionados com base no Índice de Preços ao Consumidor Amplo de 2018 no Brasil para permitir a comparação ao longo dos anos. A variação anual média dos investimentos em saúde, em Reais (BRL), foi avaliada com o uso de regressões lineares. Os coeficientes de correlação de Pearson foram estimados entre as receitas e gastos federais com os recursos das capitais. Todas as capitais apresentaram correlações estatisticamente positivas com a origem do recurso orçamentário investido em saúde. O menor coeficiente foi encontrado na cidade de Macapá (Amapá) (r = 0,860), e o mais alto em Fortaleza (Ceará) (r = 0.997). Belo Horizonte (Minas Gerais) foi a capital com o maior aumento anual em transferências federais (cerca de BRL 67,91 por ano) e Teresina (Piauí) apresentou o maior aumento anual nos gastos em saúde (cerca de BRL 55,42 por ano). Houve um aumento real nas transferências no Sistema Único de Saúde (SUS) e nos recursos municipais em quase todas as capitais, mas ainda persistem desigualdades na distribuição dos recursos financeiros entre as capitais brasileiras das cinco regiões. O financiamento da saúde é afetado pela municipalização do SUS, e não é o único fator que afeta o acesso e a qualidade dos serviços de saúde.


El objetivo fue analizar la parte de recursos financieros utilizados para financiar acciones de salud públicas en 26 capitales brasileñas, entre 2008 y 2018. Se trata de un estudio ecológico de tendencia temporal, implicando indicadores de ingresos y gastos proporcionados por el Sistema de Información sobre el Presupuesto Público para Salud (SIOPS). Se deflactaron los valores basados en el Índice de Precios al Consumidor, ampliado de 2018 en Brasil, para permitir la comparación a lo largo de los años. La variación anual media de inversiones en salud, en Reales brasileños (BRL), fue evaluada usando regresiones lineales. Se estimaron los coeficientes de correlación de Pearson entre los ingresos y gastos federales, respecto a los recursos de las capitales. Todas las capitales presentaron estadísticamente correlaciones positivas significativas respecto a la fuente presupuestaria originaria invertida en salud. El coeficiente más bajo se encontró en la capital de Macapá (Amapá) (r = 0.860) y el más alto en Fortaleza (Ceará) (r = 0.997). Belo Horizonte (Minas Gerais) fue la capital con el incremento anual más alto en transferencias federales (cerca de BRL 67.91 por año) y Teresina (Piauí) presentó el incremento anual más alto en gastos de salud entre todas las capitales (sobre BRL 55.42 por año). Hubo un incremento real de transferencias en el Sistema Único de Salud brasileño (SUS), así como recursos municipales en casi todas las capitales, pero existen todavía inequidades en la distribución de recursos financieros entre las capitales brasileñas de diferentes regiones. La financiación de la salud está afectada por la municipalización del SUS, y no es el único factor que afecta al acceso y calidad de los servicios de salud.

ABSTRACT

The objective of this article was to describe patterns of losses of information regarding accelerometer data and to assess the use of multiple imputation to generate physical activity estimates for individu-als without accelerometry data. Two birth cohort studies from Pelotas (Brazil) with participants aged 22 and 11-years old assessed objectively measured physical activity differences between complete and imputed cases. Mean values of overall physical activity for complete cases (n1993 = 2,985 and n2004 = 3,348) and for complete cases plus imputed cases (n1993 = 760 and n2004 = 79) were described accord-ing to predictors. Male individuals, participants with black skin color, and less schooled individuals presented higher averages of overall physical activity than their counterparts. Almost all imputed estimates were comparable to the complete cases, and the highest difference found was 0.7 mg for the first quintile of socioeconomic status of the 1993 birth cohort. Multiple imputation is a positive technique to deal with missing data from objectively measured physical activity. It provides a set of relevant variables to be used in order to efficiently predict accelerometer data


O objetivo desse artigo foi descrever os padrões de perda de informação em dados de acelerometria, além de avaliar o processo de imputação múltipla para estimar o nível de atividade física para indivíduos sem dados de acelerometria. Participantes de duas coortes de nascimentos de Pelotas (Brasil) com 22 e 11 anos participaram do estudo e diferenças entre casos completos e imputados foram avaliadas. A média geral de atividade física para os casos completos (n1993 = 2.985 e n2004 = 3.348) e para casos completos mais imputados (n1993 = 760 e n2004 = 79) foi descrita de acordo com os preditores. Indivíduos do sexo masculino, de cor da pele preta e com menor escolaridade apresentaram maiores médias de atividade física geral. Quase todas as estimativas imputadas foram comparáveis com os valores de casos completos, e a maior diferença encontrada foi 0,7 mg para o primeiro quintil de renda na coorte de 1993. Imputação múltipla é uma boa técnica para lidar com dados faltantes de atividade física medida por acelerometria. Essa técnica fornece um gama relevante de variáveis para serem usadas a fim de predizer valores de acelerometria eficientemente

ABSTRACT

Abstract The aim of this study was to assess and compare RANK, RANKL, and OPG immunoexpression in dentigerous cyst, odontogenic keratocyst, and ameloblastoma. The protocol was registered in PROSPERO (CRD42018105543). Seven databases (Embase, Lilacs, LIVIVO, PubMed, Scopus, SciELO, and Web of Science) were the primary search sources and two databases (Open Grey and Open Thesis) partially captured the "grey literature". Only cross sectional studies were included. The JBI Checklist assessed the risk of bias. A meta-analysis with random effects model estimated the values from the OPG and RANKL ratio reported by the individual studies and respective 95% confidence intervals. The heterogeneity among studies was assessed with I2 statistics. Only nine studies met the inclusion criteria and were considered in the analyses. The studies were published from 2008 to 2018. Two studies presented low risk of bias, while seven studies presented moderate risk. The meta-analysis showed the highest OPG>RANKL ratio for dentigerous cyst (ES=43.3%; 95% CI=14.3-74.8) and odontogenic keratocyst (ES=36.8%; 95% CI=18.8-56.7). In contrast, the highest OPG<RANKL ratio was found for ameloblastoma (ES=73.4%; 95% CI=55.4-88.4) and it was higher in the stromal region compared to the odontogenic epithelial region. The results may explain the aggressive potential of ameloblastoma from the higher OPG<RANKL ratio in this tumor, while it was lower for dentigerous cyst and odontogenic keratocyst.


Resumo O objetivo deste estudo foi avaliar e comparar a imunoexpressão de RANK, RANKL e OPG em cisto dentígero, ceratocisto odontogênico e ameloblastoma. O protocolo foi registrado no PROSPERO (CRD [Oculto]). Sete bancos de dados (Embase, Lilacs, LIVIVO, PubMed, Scopus, SciELO e Web of Science) foram as principais fontes de pesquisa e duas bases de dados (Open Grey e Open Thesis) capturaram parcialmente a "literatura cinza". Apenas estudos transversais foram incluídos. A ferramenta JBI avaliou o risco de viés. Uma metanálise com modelo de efeitos aleatórios estimou os valores da razão OPG e RANKL relatados pelos estudos individuais e seus respectivos intervalos de confiança de 95%. A heterogeneidade entre os estudos foi avaliada por meio do teste I2. Apenas nove estudos preencheram os critérios de inclusão e foram considerados nas análises. Os estudos foram publicados entre 2008 e 2018. Dois estudos apresentaram baixo risco de viés, enquanto sete estudos apresentaram risco moderado. A meta-análise mostrou a maior razão OPG> RANKL para cisto dentígero (ES=43,3%; IC95%=14,3-74,8) e ceratocisto odontogênico (ES=36,8%; IC95%=18,8-56,7). Por outro lado, a maior razão OPG <RANKL foi encontrada para ameloblastoma (ES=73,4%; IC95%=55,4-88,4) e foi maior na região estromal em comparação com a região epitelial odontogênica. Os resultados podem explicar o potencial agressivo do ameloblastoma devido a uma maior proporção OPG <RANKL nesse tumor, enquanto tal proporção foi menor no cisto dentígero e no ceratocisto odontogênico.

ABSTRACT

This study aimed to compare the effectiveness of 0.12% chlorhexidine alone and 0.12% chlorhexidine in combination with toothbrushing to prevent ventilator-associated pneumonia (VAP) in mechanically ventilated patients. The Embase, Latin American and Caribbean Health Science Literature, PubMed, Scientific Electronic Library Online, Scopus, LIVIVO, Web of Science, Cochrane Library, OpenThesis, and Open Access Thesis and Dissertations databases were used. Only randomized controlled trials without restrictions on the year or language of publication were included. Two reviewers assessed the risk of bias using the Joanna Briggs Institute Critical Appraisal Tool. A meta-analysis using a random-effects model estimated the combined relative risk (RR). The Grading of Recommendations, Assessment, Development and Evaluations approach was used to assess the certainty of the evidence. Initially, 2,337 studies were identified, of which 4 were considered in the systematic review and 3 in the meta-analysis (total sample: 796 patients). The studies were published between 2009 and 2017. All eligible studies had a low risk of bias. The meta-analysis revealed that the risk of VAP was 24% lower in patients receiving chlorhexidine combined with toothbrushing than in those receiving chlorhexidine alone (RR: 0.76; 95% confidence interval: 0.55-1.06), with moderate certainty of evidence and without statistical significance. In conclusion, considering the limitations of this study, a standard protocol for the prevention of VAP is not yet recommended. More studies with larger sample sizes are needed to draw strong conclusions. However, considering that toothbrushing is a simple intervention, it should be a common practice in mechanically ventilated patients, especially among patients with coronavirus disease.

ABSTRACT

Abstract: This study aimed to assess the survival of glass ionomer cement (GIC) restorations performed using the atraumatic restorative treatment (ART) in elderly patients. The systematic review protocol was registered in the PROSPERO database. The records were searched until August 2020 in eight electronic bibliographic databases, and included randomized and non-randomized clinical trials and observational studies, with no restrictions on the language or year of publication. Study selection and data extraction were performed independently by two reviewers. Data were extracted, summarized, collected for qualitative analysis, and evaluated for individual risk of bias using the Joanna Briggs Institute's Critical Appraisal Tool. The literature search retrieved 5,186 records; however, only seven studies fulfilled the eligibility criteria and were included. The studies were published between 2002 and 2019. A total of 1,239 restorations were investigated at intervals of 6, 12, 24, and 60 months of follow-up. Some studies had a low risk of bias, while others had moderate and high risk of bias. In general, GIC restorations placed using ART were considered satisfactory. The 6-month, 12-month, and 24-month survival rates ranged from 81.3% to 97.2%, 72.2% to 94%, and 63% to 87%, respectively; additionally, the survival rate for the longest follow-up period (60 months) was 85%. Given the best evidence-based information regarding caries removal, we highlight the need to provide a conservative and effective technique for use in elderly patients. ART is a promising and viable alternative that guarantees the survival of restorations in elderly patients.

ABSTRACT

ABSTRACT: Objective: The aims of this study were: 1) to estimate the prevalence of multimorbidity in 2013 and 2019 in adults aged 20-59 years; 2) to assess inequalities in the prevalence of multimorbidity in 2013 and 2019 according to educational level. Methods: Data from two cross-sectional surveys from the Brazilian National Health Survey in 2013 and 2019 were used. Multimorbidity was assessed from 14 lifetime self-reported morbidities (except back problems) and defined using the cutoff point of ≥2 diseases. The prevalence of multimorbidity and individual morbidities were described according to gender, age, skin color, and education. For education, crude, and relative inequalities in prevalence of multimorbidity were calculated using the Slope Index of Inequality and the Concentration Index, respectively. Results: The prevalence of multimorbidity increased from 18.7% (95%CI 18.0-19.3) in 2013 to 22.3% (95%CI 21.7-22.9) in 2019, being higher among women and adults between 30-59 years in both periods. Asthma/bronchitis, depression, and back problems were the conditions that increased the most in the study period. Absolute and relative inequalities by education status were observed in the study period, with worse multimorbidity profiles among the less educated. Conclusion: The prevalence of multimorbidity increased between 2013 and 2019. Inequalities in the prevalence of multimorbidity were observed according to educational level.


RESUMO: Objetivos: Os objetivos do presente estudo foram: 1) estimar a prevalência de multimorbidade nos anos de 2013 e 2019 em adultos de 18 a 59 anos; 2) avaliar as desigualdades na prevalência de multimorbidade em 2013 e 2019, de acordo com a escolaridade. Métodos: Foram utilizados dados de dois inquéritos transversais da Pesquisa Nacional de Saúde de 2013 e 2019. A multimorbidade foi avaliada a partir de 14 morbidades autorreferidas a partir de diagnóstico médico na vida (exceto problema na coluna) e definida usando-se o ponto de corte de ≥ 2 doenças. As prevalências de multimorbidade e morbidades individuais foram descritas de acordo com sexo, idade, cor da pele e escolaridade. Desigualdades brutas e relativas nas prevalências conforme a escolaridade foram calculadas utilizando-se o Slope Index of Inequality e o Concentration Index, respectivamente. Resultados: A prevalência de multimorbidade aumentou de 18,7% (IC95% 18,0-19,3), em 2013, para 22,3% (IC95% 21,7-22,9), em 2019, sendo maior entre mulheres e adultos entre 30 e 59 anos em ambos os períodos. Asma/bronquite, depressão e problemas na coluna foram as condições que mais aumentaram no período. Desigualdades absolutas e relativas foram observadas, com prevalências superiores entre os menos escolarizados e sem diferença entre os anos. Conclusões: A prevalência de multimorbidade aumentou no período de 2013 a 2019. Desigualdades na prevalência de multimorbidade foram observadas de acordo com a escolaridade.

ABSTRACT

The aim of this study was to test reliability of the Global Physical Activity Questionnaire (GPAQ), and its concurrent validity using accelerometers, in a Brazilian rural population. Fifty-five adults (18+ years) living in a rural Brazilian city were selected to wear an accelerometer for one week and to an-swer the GPAQ twice in a week period interval. Reliability was verified using Intraclass Correlation Coefficients and the concurrent validity was analyzed based on Bland and Altman's diagrams. We found relatively high reliability for the total physical activity (ICC = 0.78; 95%CI: 0.63; 0.87). The average difference between both GPAQ measures was 192 minutes (95%CI: -69.63; 453.75). Wider differences were found when participants reported > 400 minutes of physical activity per week. There was limited agreement between the GPAQ and accelerometer measures (total average difference = -1043 minutes; 95%CI: -1452.23; -634.09). Thus, the questionnaire presented limited concurrent validity and acceptable reliability, being able to be used in rural populations. However, there is still a need of new physical activity instruments focused on rural populations


O objetivo deste estudo foi realizar um teste-reteste do Questionário Global de Atividade Física (GPAQ) e sua validade concorrente com acelerômetros em uma população rural brasileira. Cinquenta e cinco adultos (18 anos ou mais) moradores da área rural da cidade de Arroio do Padre foram selecionados para responder o GPAQ em duas semanas subsequentes e usar um acelerômetro por uma semana. Para realizar o teste-reteste foi usado o coeficiente de correlação intraclasse (CCI) e a validade concorrente foi analisada usando gráficos Bland and Altman. O resultado do teste-reteste de atividade física total foi alto (CCI = 0,78; IC95%: 0,63; 0,87). A diferença média entre as duas medidas do GPAQ foi 192 minutos (IC95%: -69.63; 453.75). Maiores diferenças foram encontradas quando os participantes reportaram praticar mais de 400 minutos de atividade física por semana. A concordância foi limitada entre as medidas do GPAQ e do acelerômetro (diferença média total = -1043 minutos; IC95%: -1452.23; -634.09). Logo, o GPAQ apresentou limitada validade concorrente e aceitável teste-reteste, podendo ser usado em populações rurais. Contudo, a criação de um novo instrumento de atividade física focado na população rural é necessária

ABSTRACT

O objetivo do presente estudo foi comparar as estimativas de atividade física e comportamento se-dentário obtidas pelos inquéritos nacionais VIGITEL e PNS. Foram utilizados dados do VIGITEL 2013 e PNS 2013, conduzidos entre adultos (≥ 18 anos).Os desfechos foram: atividade física no lazer, deslocamento ativo para o trabalho, inatividade física no lazer e tempo de televisão. Sexo, idade, escolaridade e índice de massa corporal foram as variáveis independentes. Para a estatística, utilizou--se proporções (IC95%) e Coeficiente de Correlação de Concordância de Lin (CCC). As estimativas de deslocamento ativo para o trabalho e de tempo de TV apresentaram concordância moderada entre os inquéritos (CCC = 0,515; CCC = 0,478, respectivamente), enquanto as estimativas de atividade física no lazer e inatividade no lazer apresentaram concordância baixa (CCC = 0,060; CCC = 0,054, respectivamente). As estimativas obtidas entre os inquéritos PNS e VIGITEL sobre desfechos relacionados à atividade física e comportamento sedentário foram de concordância moderada a baixa, não sendo os resultados obtidos comparáveis


The aim of the present study was to compare estimates of physical activity and sedentary behavior by two Brazilian surveys, VIGITEL PNS. Were used data from VIGITEL 2013 and PNS 2013, conducted among adults (≥ 18 y). Were adopted as outcomes: leisure-time physical activity, active transportation to work, leisure-time physical inactivity and TV time. Sex, chronological age, race, educational status, marital status and body mass index were independent variables. For statistical analyses, proportions (IC95%) and Lin's concordance correlation coefficient (CCC) were calculated. The estimates of active transportation for work and TV viewing showed moderate agreement between the surveys (CCC = 0.515; CCC = 0.478, respectively), while estimates of leisure activity and leisure physical inactivity showed a low agreement (CCC = 0.060; CCC = 0.054, respectively). Agreement between the estimates of physical activity and sedentary behavior provided by the VIGITEL and PNS ranged from moderate to poor and the results are not comparable
