[Obesity in adults: a population based study in a small town in South of Brazil, 2005]. / Obesidade em adultos: estudo de base populacional num município de pequeno porte no sul do Brasil em 2005.

Changes in nutritional pattern in Brazilian population have been observed mainly in relation to obesity increase. This study aims to estimate the prevalence of obesity and associated factors in adult population in Santo Angelo, Rio Grande do Sul State, 2005. A cross sectional study was carried out involving adult subjects from 20 to 59 years old (n=434), of both sexes. People with Body Mass Index equal to or higher than 30 kg/m(2) were considered obese. A questionnaire was applied to collect data related to socioeconomic, demographic, and behavioral conditions. The multiple logistic regression analysis was performed to identify the associated factors. The response rate was 95.0% and the prevalence of obesity was equal to 16.6% (CI 95% 13.120.1). Presence of obesity was positively associated with lack of physical activity, none feeding habits care, and some individuals that mentioned current health problems regardless of sex. The prevalence of obesity found was similar to other Brazilian population based studies. The results may support planning and implementing prevention actions as well as obesity control in adult population taking into account the relevant details of a small size town.

Mudanças nos indicadores nutricionais na população brasileira têm sido observadas, especialmente no que se refere ao incremento da obesidade. O objetivo foi estimar a prevalência de obesidade e fatores associados na população adulta, em Santo Ângelo (RS), em 2005. Realizou-se um estudo transversal com indivíduos de 20 a 59 anos (n=434), de ambos os sexos. Foram considerados obesos os indivíduos que apresentaram índice de massa corporal igual ou superior a 30 Kg/m². Foram investigadas questões sobre as condições socioeconômicas, demográficas e comportamentais dos indivíduos. Realizou-se a análise de regressão logística múltipla para identificação dos fatores associados. A taxa de resposta foi igual a 95,0 por cento e a prevalência de obesidade foi igual a 16,6 por cento (IC95 por cento 13,120,1). Presença de obesidade foi associada positivamente a indivíduos que não praticavam atividade física, àqueles que afirmaram não ter nenhum cuidado com a alimentação e aos que relataram algum problema de saúde atual, independentemente do sexo dos indivíduos. A prevalência de obesidade encontrada foi semelhante a outros estudos de base populacional já realizados no país. Os resultados deste estudo podem auxiliar no planejamento e implantação de ações de prevenção e controle da obesidade em adultos, respeitando-se as particularidades de um município de pequeno porte.
