CONTARATO, Aila Anne Pinto Farias et al. Independent effect of type of breastfeeding on overweight and obesity in children aged 12-24 months. Cad. Saúde Pública [online]. 2016, vol.32, n.12, e00119015.  Epub Dec 22, 2016. ISSN 1678-4464.

This study aimed to analyze the effect of type of breastfeeding on the nutritional status of children between 12-24 months of age. This cohort study included 435 children born in 2012 in a public hospital in Joinville, Santa Catarina State, Brazil. Two years after delivery the mothers and their children were contacted in their homes for a new investigation of demographic, economic, nutritional, and anthropometric data. In the unadjusted analysis, children who were not exclusively breastfed were more likely to be overweight (including obesity) at 2 years of age (OR = 1.6; p = 0.049) than exclusively breastfed children. After adjusting for several covariates, children who were not exclusively breastfed had a 12% higher risk of overweight including obesity compared to unadjusted analysis (OR = 2.6 vs. OR = 1.8; p = 0.043). In addition, birthweight was also an independent determinant of overweight including obesity (OR = 2.5; p = 0.002). The practice of exclusive breastfeeding can reduce the risk of overweight in children from developing countries such as Brazil.
