Comparative study of the nutritional status of children living in four counties of the province of Buenos Aires (Argentina), in the context of nutrition transition

Abstract

The aim of this study was to evaluate and compare the nutritional status of child populations living in four counties of the province of Buenos Aires to observe differences related to particular environmental and socioeconomic contexts in the framework of the nutrition transition. During the school years corresponding to the 2008- 2012 period, weight and height were measured and body mass index was calculated for 7,873 school children between the ages of 4 and 12 years from the counties of La Plata, Brandsen, Magdalena and Punta Indio. Information about the contexts of residence was obtained using self-administered structured surveys. About 40% of schoolchildren presented malnutrition, with a prevalence of overweight in La Plata, obesity in Punta Indio and undernutrition in Magdalena. The nutritional status of the study populations was associated with the socioenvironmental conditions of residence, indicating that these populations are at different stages of the nutrition transition process.
