* Excess body weight: BMI ≥ 25 kg/m² (WHO, 1998), BMI ≥ 28 kg/m² (OPAS, 2002) for adults and elderly respectively. ** Obesity: BMI ≥ 30 kg/m² (WHO, 1998; OPAS, 2002). ^† Sample represents 1028 participants with excess body weight and 271 with obesity. Poisson regression Model 1: adjusted for age and sex. Poisson regression Model 2: adjusted for sex (female/male), age (years), alcohol consumption (yes/no), physical activity (yes/no), smoking (never smoked/former smoker/currently smoke), television hours per day (>1 h/ ≤1 h), use of vitamin supplement (yes/no), and daily caloric intake.
