title: [Risk factors for overweight in children from Southern Brazil].
abstract: Risk factors for overweight were investigated in a cross-sectional survey of children aged 12-59 months in the Southern Brazilian city of Porto Alegre (n = 2,660). Odds ratios (OR) for overweight, defined by weight/height > 2 z-scores of the NCHS standards, were estimated for socioeconomic and demographic conditions, social environment, and childhood health events. Prevalence of overweight was 6.5%. In the multivariate model, the odds of overweight were positively associated with maternal education (schooling > 12 years, OR = 2.36; 95%CI: 1.21-4.60; 9-11 years, OR = 2.07; 95%CI: 1.16-3.70) and family income per capita > 2 times the minimum wage (OR = 1.86; 95%CI: 1.13-3.08) and negatively associated with maternal work (OR = 0.72; 95%CI: 0.52-0.99). Odds were higher for children born large-for-gestational-age (OR = 2.29; 95%CI: 1.36-3.85) and lower for children born small (OR = 0.57; 95%CI: 0.33-0.99), as compared to those born with adequate birth weight for gestational age. Paternal schooling, parental occupation, and maternal age at the child's birth were associated with overweight in the unadjusted model only. Programs are needed to prevent overweight during childhood, with special attention to families and children at increased risk.
