Overweight among adults in Pernambuco State, Brazil: prevalence and associated factors

In order to evaluate the prevalence of overweight and associated factors in Pernambuco State, Brazil, a cross-sectional population-based study was conducted in 2006, including 1,580 adults 25 to 59 years of age. Overweight was defined as body mass index > 25kg/m2. The conceptual model included demographic, socioeconomic, reproductive, and behavioral variables. Prevalence of overweight was 51.1% (95%CI: 48.6-53.6) and was statistically associated with age over 40 years (PR = 1.27; 95%CI: 1.10-1.46), female gender (PR = 1.29; 95%CI: 1.16-1.43), former smoking (PR = 1.42; 95%CI: 1.20-1.69), higher income (PR = 1.49; 95%CI: 1.30-1.71), and history of early pregnancy (< 18 years) (PR = 1.25; 95%CI: 1.11-1.66). There was no association with alcohol consumption, level of physical activity, or specific foods. The high prevalence of overweight is consistent with epidemic levels of this problem elsewhere in world, and the association with several factors supports its multifactor etiology.
