Resumo Introdução O suicídio é uma das três causas de morte mais frequentes no mundo e varia conforme o sexo e a idade. Objetivo Analisar a tendência da mortalidade por suicídio nas regiões brasileiras no período de 1996 a 2015 e sua associação com o sexo e a faixa etária. Método Estudo ecológico de série temporal, utilizando os óbitos por suicídio analisados por regiões no período de 1996 a 2015 contidos no Sistema de Informações sobre Mortalidade. Para avaliação da tendência da mortalidade por suicídio, foi considerado o modelo de regressão de Prais-Winsten. Para comparar os percentuais de mortalidade por sexo e faixa etária, foi utilizado o teste qui-quadrado. Resultados Observou-se tendência crescente de óbitos por suicídio nas regiões Norte (1,73%, Coef = 0,007; p-valor < 0,001), Nordeste (2,30%, Coef = 0,010; p-valor = 0,006) e Sudeste (1,41%, Coef = 0,006; p-valor < 0,001) e decrescente no Sul (-0,57%, Coef = -0,002; p-valor = 0,001), além de predomínio de homens no percentual de óbitos (p < 0,001). Conclusão O suicídio é considerado importante problema de saúde pública, necessitando de ações para divulgação dos riscos e programas de prevenção.

This study focused on the association between physical activity in the second trimester of pregnancy and adverse perinatal outcomes: low birth weight (LBW), preterm birth (PTB), and intrauterine growth restriction (IUGR). The study used a sample from the BRISA cohort, São Luís, Maranhão State, Brazil, which included women with singleton pregnancy, gestational age from 22 to 25 weeks confirmed by obstetric ultrasound performed at < 20 weeks, and re-interviewed in the first 24 hours postpartum (n = 1,380). Level of physical activity was measured by the International Physical Activity Questionnaire (IPAQ), short version, categorized as high, moderate, and low. A directed acyclic graph (DAG) was used to identify minimum adjustment to control confounding. High physical activity was not associated with LBW (RR = 0.94; 95%CI: 0.54-1.63), PTB (RR = 0.86; 95%CI: 0.48-1.54), or IUGR (RR = 0.80; 95%CI: 0.55-1.15). The results support the hypothesis that physical activity during pregnancy does not result in adverse perinatal outcomes.

This study aimed to validate the internal structure of the Brazilian version of the Baecke Habitual Physical Activity Questionnaire. A cross-sectional study was conducted with individuals over 18 years old of both sexes, with Brazilian Portuguese as their native language. The structure of the Baecke Habitual Physical Activity Questionnaire was tested by confirmatory factor analysis. The model fit was evaluated by the following indices: root mean square error of approximation, comparative fit index, Tucker-Lewis index, standardized root mean square residual, and χ²/degrees of freedom. We used the Akaike information criterion and Bayesian information criterion to compare different structures of the Baecke Habitual Physical Activity Questionnaire. A total of 241 individuals participated in this study. The original structure of the Baecke Habitual Physical Activity Questionnaire with 16 items and 3 domains was compared to a structure with 14 items and 3 domains. The internal structure of the Baecke Habitual Physical Activity Questionnaire with 14 items showed better fit indices and lower Akaike information criterion and Bayesian information criterion values. The best internal structure of the Brazilian version of the Baecke Habitual Physical Activity Questionnaire in adults presents 3 domains and 14 items.

INTRODUCTION: Congenital syphilis is considered a severe public health problem because it accounts for approximately 40% of the perinatal mortality rates, 25% of stillbirths, and 14% of neonatal deaths, in addition to causing severe consequences for the fetus. This study aimed to describe the rates of congenital syphilis in children under one year of age in Brazilian capitals from 2009 to 2016. METHODS: Ecological time series study, using rates of congenital syphilis in children under one year of age and living in Brazilian capitals. The Prais-Winsten regression model was used to assess the trend. RESULTS: A total of 44,056 cases of congenital syphilis in children under one year of age were reported in Brazilian capitals between 2009 and 2016. The highest rate of congenital syphilis in children under one year of age occurred in 2016 in Porto Alegre (31.07/1,000 live births). The Northeastern capitals showed high rates, particularly the capital Recife (23.67/1,000 live births). CONCLUSIONS: Congenital syphilis represents a major challenge for public policies. The need for improvements in the quality of prenatal care is highlighted, as it is essential to reduce the alarming rates.

BACKGROUND: The Finnish Diabetes Risk Score (FINDRISC) is a questionnaire that was developed by Finnish researchers to track the risk of diabetes. OBJECTIVE: To translate, cross-culturally adapt and validate the FINDRISC for use in Brazilian Portuguese. DESIGN AND SETTING: Questionnaire validity study conducted at a private university. METHODS: The Brazilian version of the FINDRISC was developed through the processes of translation, back-translation, committee review and pre-testing. Test-retest reliability was measured using the intraclass correlation coefficient (ICC), kappa coefficient, standard error of measurement (SEM) and minimum detectable change (MDC). Internal consistency was measured using Cronbach's alpha. For construct validity, the total score of the FINDRISC was correlated with the Diabetes Knowledge Scale (DKN-A) and Diabetes Mellitus Risk Questionnaire (QRDM). Ceiling and floor effects were also evaluated in the present study. RESULTS: For construct validity and floor and ceiling effect measurements, a total sample of 107 participants was used. For reliability, a subsample of 51 participants out of the total sample was used. We identified adequate values for reliability (kappa = 0.79 and ICC = 0.98) and internal consistency (Cronbach's alpha = 0.84). Regarding the error inherent in the FINDRISC, we found SEM = 8.02% and MDC = 22.44%. There were significant correlations between the FINDRISC and the QRDM (r = 0.686) and DKN-A (r =-0.216). No ceiling or floor effects were found. CONCLUSION: The Brazilian version of the FINDRISC has adequate psychometric properties that are in accordance with the best international recommendations.
