RESUMO
Population studies in Brazil have shown an increased prevalence of overweight and obesity in adult populations in all regions of the country. The objective was to estimate prevalence and identify risk factors associated with overweight among adults in Rio Branco, Acre State, Brazil. The study included a cross-sectional population-based sample of 1,469 adults. Multivariate analysis was performed using Poisson regression, taking overweight (BMI > 25kg/m²) as the dependent variable. Prevalence of overweight was 46.9%, higher among women. Overweight tended to increase with age in both men and women. Overweight was associated with socioeconomic, demographic, and morbidity variables such as hypertension and dyslipidemia. The high prevalence of overweight in adults of both sexes suggests a public health problem. Control measures and prevention of health risks associated with excess weight are necessary.

Estudos populacionais no Brasil apontam aumento da prevalência de excesso de peso e obesidade na população adulta, em todas as regiões. O objetivo deste estudo foi estimar a prevalência e identificar os principais fatores associados ao excesso de peso em adultos, em Rio Branco, Acre, Brasil, por meio de um estudo transversal de base populacional com amostra composta de 1.469 adultos. A análise multivariada foi realizada através de regressão de Poisson, adotando-se, como variável dependente, excesso de peso (IMC > 25kg/m²). A prevalência de excesso de peso foi observada em 46,9 por cento da amostra, sendo mais elevada entre as mulheres. Observou-se tendência de aumento do excesso de peso com o aumento da idade em ambos os gêneros. Observaram-se associações entre o excesso de peso e variáveis socioeconômicas, demográficas e morbidades como hipertensão arterial e dislipidemias. A alta prevalência de excesso de peso em adultos de ambos os sexos sugere um problema de saúde pública. Tornam-se necessárias medidas de controle e prevenção dos riscos à saúde associados ao excesso de peso.
