Níveis de intervenção para obesidade abdominal: Prevalência e fatores associados

Abstract

During 1999 and 2000, a population-based cross-sectional study was conducted in Pelotas, southern Brazil, to describe the population distribution of abdominal adiposity according to "action level points" and to identify risk factors. The study included a sample of 1,935 adults (20-69 years) residing in urban areas. Abdominal obesity was classified as action level I for waist circumference (WCLI) 80-88cm in women and 94-102cm in men; and as action level II (WCLII) for > 88cm in women and > 102cm in men. Abdominal obesity was present in 62% of women and 37% of men. Some 23% and 19% of men and women were classified as WCLI, respectively; 39% of women and 19% of men were classified as WCLII. After adjustment for confounding variables, age and being married or in a stable relationship were strongly associated with WCLII. Schooling was a risk factor in men only, and family income in women. In women, income was inversely associated with abdominal obesity. Use of a simple measurement such as waist circumference, which allows identification of levels of intervention, should be incorporated into health promotion measures, especially to help community health workers monitor the population needs.
