RESUMO
Brazil is experiencing among the world's fastest demographic aging worldwide. This demographic transition is occurring in a context of few resources and great social inequalities. The Brazilian Longitudinal Study of Aging (ELSI-Brazil) is a nationally representative study of 9,412 people aged 50 years or older, residing in 70 municipalities across the 5 Brazilian regions. ELSI-Brazil allows investigations of the aging process, its health, psychosocial and economic determinants, and societal consequences. The baseline examination (2015-2016) included detailed household and individual interviews and physical measurements (blood pressure, anthropometry, grip strength, and timed walk and balance tests). Blood tests and sample storage were performed in a subsample of study participants. Subsequent waves are planned for every 3 years. The study adopts a conceptual framework common to other large-scale longitudinal studies of aging in the world, such as the Health and Retirement Study, allowing cross-national comparisons. The goal of ELSI-Brazil is not only to build an understanding of aging in a large, Western, middle-income country in a rapid demographic transition but also to provide scientific data to support and study policy changes that may affect older adults. We describe the methodology of the study and some descriptive results of the baseline survey.

OBJECTIVE: To examine the prevalence of disordered eating behaviors among adolescents and adults living in the same household. METHODS: We conducted a population-based cross-sectional study developed with a probabilistic sample of 511 adolescents and 1254 adults living in the metropolitan area of Rio de Janeiro, Brazil. The frequency of binge eating, purging, and strict dieting or fasting over the previous 6 months was ascertained using a self-report questionnaire. RESULTS: Binge eating (20.0% vs. 8.4%), strict dieting or fasting (18.9% vs. 2.4%), and purging (3.3% vs. 2.2%) were more frequent among adolescents than adults. There was a significant association between frequency of binge eating and strict dieting or fasting in adults and in adolescents living in the same household. CONCLUSION: The presence of disordered eating behaviors in adults may be a risk factor for the development of eating disorders in adolescents living in the same household. Thus, the development and implementation of eating disorder interventions should consider incorporating a family component.

PURPOSE: To evaluate sociodemographic, behavioral and reproductive factors and morbidities associated with inadequate weight gain during pregnancy. METHODS: Cohort study conducted from December 2007 to August 2008 with women in the first trimester of pregnancy looking for prenatal care in the Public Health System who lived in the cities of Petrópolis or Queimados, Rio de Janeiro state (Brazil). Women with multiple pregnancy, who had a miscarriage in the index pregnancy or who lacked information for the assessment of pregravid nutritional status or weight gain were excluded. Pregravid nutritional status and weight gain during pregnancy were determined according to the criterion established by the Institute of Medicine (IOM). Statistical analysis was performed using a multinomial logistic regression model. RESULTS: A total of 1,287 women were included in the study; 26.6% of them were overweight or obese while 11% were underweight. Inadequate weight gain during pregnancy was observed in 71.4% of pregnant women; 35.6% of them did not gain enough weight while 35.8% gained more weight than recommended by the IOM. In the multivariate analysis, women with hypertension (OR=2.1; 95%CI 1.4-3.1), pregravid overweight (OR=2.5; 95%CI 1.4-4.5) or obesity (OR=2.7; 95%CI 1.8-3.9) and who had a higher educational level were more likely to gain more weight than recommended, while pregravid underweight (OR=0.6; 95%CI 0.4-0.9) represented a protection against excessive gain. CONCLUSION: Pregravid nutritional diagnosis and weight gain monitoring should be actions effectively instituted in the routine of health professionals.
