Epidemiologia da obesidade abdominal em mulheres adultas residentes no sul do Brasil Abdominal obesity epidemiology amongst adult women resident in Southern Brazil.
Abstract
Foi realizado um estudo transversal de base populacional com uma amostra representativa de 981 mulheres de 20 a 60 anosresidentes no sul do Brasil para investigar o efeito de fatores socioeconômicos, demográficos e do estilo de vida na ocorrência deobesidade abdominal. Adiposidade abdominal foi avaliada através da circunferência da cintura (CC) em centímetros (cm). Para descrevera amostra CC foi agrupada em três categorias: adequada (CC The objective of this study was to investigate the risk factors associated with abdominal obesity in women. A cross-sectional population based study was carried out on 981 women aged 20 to 60 years living in Southern Brazil. Abdominal adiposity was assessed by waist circumference (WC) = 88 cm. Poisson regression models were used to obtain prevalence ratios (PR) and their confidence intervals. The abdominal obesity prevalence was 23,3% (IC95%: 20,7-26,0). The main factors associated with the outcome were: having low education level, being unemployed, being more than 40 years old, having family obesity history, and being married. Adjusted analyses showed increased obesity prevalence in hypertensive women (Prevalence Ratio - PR=2,06; CI95%: 1,58 - 2,69) and those having higher number of children (PR=1,17; CI95% 1,00 - 1,37). Later menarche, at 12-13 years and at 14 years of age, protected against obesity comparing to women with earlier menarche at 8-11 years, respectively, 31% and 46% of protection. The understanding of how the abdominal obesity is distributed among the population allows effective planning and action implementation towards the reduction rates of this nutritional and public health problem.
