Child Nutrition and Water Access

Background: Nutritional transition has been described in various countries, each showing inherent characteristics. Furthermore, different patterns also appear within the same country.Aim: To compare the nutritional status of schoolchildren, of both sexes, living in two Argentine cities with different urban and environment characteristics, from the perspective of nutritional transition.Subjects and methods: The sample comprised 5355 children (6–13 years) living in Puerto Madryn (Chubut) and General Alvear (Mendoza), Argentina. Weight and height were transformed into Z-scores according to NHANES I- II; underweight, stunting and wasting defined by − 2 SD and overweight and obesity calculated according the cut-off proposed by IOTF. Prevalences of nutritional status were estimated.Results: Comparison of the two cities revealed significant χ2 values for the indicators of nutritional status analysed. Puerto Madryn had higher prevalences of overweight and obesity. General Alvear exhibited higher stunting and underweight values.Conclusions: The cities studied are in different stages of nutritional transition. Puerto Madryn is undergoing growing industrialization and urbanization and thus exhibits characteristics typical of an 'obesogenic' environment. General Alvear, a less complex urban centre, where some cultural patterns related to an agrarian way of life appear to have been retained, is situated at a less advanced stage.
