The aim of this study was to evaluate body composition in relation to nutritional status and socio-environmental conditions of residence in schoolchildren living in the urban periphery of La Plata, Argentina. Weight, height, arm circumference and tricipital and subscapular skinfolds were measured in 3,284 schoolchildren aged 4-12 years in the period 2014-2017. The National Health and Nutrition Examination Survey (NHANES) III reference was used to assess nutritional status, identifying the following categories: normal, underweight, stunting, wasting, overweight and obesity. Body composition was evaluated based on upper arm muscle area (UMA) and upper arm fat area (UFA). Deficit and excess UMA and UFA were also calculated. Central fat distribution was determined with the subscapular-tricipital index. Socio-environmental characteristics were surveyed using a structured questionnaire. The prevalence of nutritional status and body composition indicators were compared by sex using Chi square test. Socio-environmental data were analyzed using categorical Principal Component Analysis, discriminating into more favorable and unfavorable conditions. Nutritional status results were as follows: normal, 64.5%; stunting, 3.4%; underweight, 0.0%; wasting, 0.1%; overweight, 15.6% and obesity 16.4%. The nutritional status of children worsened as the socio-environmental condition of their families became more precarious. Long-term socio-environmental stress manifested as decreased muscle tissue in normal, stunted, overweight and obese children. The current results evidence the strong impact of poverty on child growth and development and at the same time enforce the need for continuous monitoring of children with hidden malnutrition(AU)
