The purpose of this study was to assess the prevalence and factors associated with overweight and obesity (OW/O) among Brazilian adolescents, based on the Living Standards Survey conducted in 1996 and 1997 (IBGE, 1998a). The sample included 1,027 and 854 adolescents aged 15 to 19 years from the Northeast and Southeast regions, respectively. Body Mass Index (w/h2) was calculated. Statistical analysis considered expansion factors and sample design. Prevalence of OW/O was 8.45% in the Northeast and 11.53% in the Southeast. In the Northeast there was a higher risk of OW/O for girls (PR = 3.00), with the same situation in both urban (PR = 3.21) and rural areas (PR = 2.27). In the Southeast, the risk of OW/O was lower among girls (PR = 0.58). The same situation occurred in girls from urban areas (PR = 0.51), but in rural areas there was an increased risk among girls (PR = 1.86). Per capita monthly income was associated with the risk of OW/O among boys in both regions. Programs to prevent OW/O should incorporate nutritional reeducation and encourage physical exercise, besides considering socioeconomic, cultural, and regional differences and the location of the target population.

OBJECTIVE To describe the trend in cancer mortality rates in Brazil and regions before and after correction for underreporting of deaths and redistribution of ill-defined and nonspecific causes.METHODS The study used data of deaths from lung cancer among the population aged from 30 to 69 years, notified to the Mortality Information System between 1996 and 2011, corrected for underreporting of deaths, non-registered sex and age , and causes with ill-defined or garbage codes according to sex, age, and region. Standardized rates were calculated by age for raw and corrected data. An analysis of time trend in lung cancer mortality was carried out using the regression model with autoregressive errors.RESULTS Lung cancer in Brazil presented higher rates among men compared to women, and the South region showed the highest death risk in 1996 and 2011. Mortality showed a trend of reduction for males and increase for women.CONCLUSIONS Lung cancer in Brazil presented different distribution patterns according to sex, with higher rates among men and a reduction in the mortality trend for men and increase for women.

This article offers a simple predictive model of physical intimate partner violence (PIPV) to be used by primary health care (PHC) professionals. The sample comprised 811 mothers of children <5 months old attending PHC facilities in Rio de Janeiro, Brazil. A multinomial logit model was used. Measured by the Revised Conflict Tactics Scales, PIPV was classified in three levels (absence, at least one episode during pregnancy or postpartum, and presence in both periods). Socio-economic, demographic and life style variables were considered as potential predictors. Maternal age <20 years, an education of <8 years of schooling, raising >2 children under 5, tobacco smoking, alcohol misuse and illicit drug use by the mother and/or partner, and perception of baby's ill-health were identified as predictors of PIPV. The model-projected prevalence of PIPV for pregnancy and/or postpartum was just 10.1% in the absence of these characteristics, whereas this increased to 96.4% when all the seven characteristics were present. Child, maternal and family characteristics greatly increase the likelihood of PIPV and could be used together as screening indicators.

The objectives of this study were to estimate the prevalence of postpartum posttraumatic stress disorder (PTSD)
