Abstract

The scope of this study was to verify the association between risk behaviors and obesity in adults (18 to 59 years of age) in Brazilian capitals. It involved a cross-sectional population-based study conducted by telephone interview. The self-reported variables were obesity, defined by weight and height (BMI ≥ 30 kg/m²) and risk behaviors: physical inactivity (≤ 149 minutes/week), excess sedentarism (≥ 4 hours/day), frequent consumption of sweets (≥ 5 days/week) and meat with fat and/or chicken with skin (≥ 1 day/week). The simultaneity of risk behaviors was analyzed for reasons of observed and expected prevalence. The Poisson and multinomial logistic regressions were used in crude analyses and adjusted for sociodemographic factors. Among the 35,448 adults, the simultaneous consumption of meat with fat, excess sedentarism and physical inactivity (PR: 1.94, 95% CI: 1.45, 2.60), as well as the presence of the four risk behaviors (PR: 1.72, 95% CI: 1.16, 2.53) were associated with obesity in men. In women, the simultaneous consumption of sweets and meat with fat (PR: 1.77, 95% CI: 1.19, 2.66) was also associated with the outcome. In both sexes, there was an increase in the tendency of obesity according to the sum total of risk behaviors.

Objetivou-se verificar a associação da simultaneidade de comportamentos de risco com a obesidade em adultos (18 a 59 anos) das capitais do Brasil. Trata-se de um estudo transversal de base populacional, realizado por entrevista telefônica. As variáveis autorrelatadas foram a obesidade, definida pelo peso e altura (IMC ≥ 30 kg/m²) e os comportamentos de risco: inatividade física (≤ 149 min/sem), tempo sentado em excesso (≥ 4h/dia), consumo frequente de doces (≥ 5 dias/sem) e de carnes vermelhas com gordura e/ou frango com pele (≥ 1 dia/sem). A simultaneidade dos comportamentos de risco foi analisada por razões das prevalências observadas e esperadas. Foram utilizadas as regressões de Poisson e logística multinomial, em análises por sexo, brutas e ajustadas por fatores sociodemográficos. Dentre os 35.448 adultos, nos homens, a simultaneidade do consumo de carnes com gordura, tempo sentado em excesso e inatividade física (RP: 1,94; IC95%: 1,45; 2,60), assim como a presença dos quatro comportamentos de risco (RP: 1,72; IC95%: 1,16; 2,53), associaram-se à obesidade. Em mulheres, o consumo simultâneo de doces e de carnes com gordura (RP: 1,77; IC95%: 1,19; 2,66) também se associou ao desfecho. Em ambos os sexos, observou-se aumento da tendência de obesidade conforme o somatório de comportamentos de risco.
