The aim was to know and to analyse the prevalence of undernutrition and body composition and proportion in relationship to socio-environmental conditions of residence in children of two adjacent departments in the province of Mendoza: San Rafael (SR) and General Alvear (GA). A crosssectional anthropometrical study was performed in 5.118 children from 5 to 12 years old. Body weight, height, sitting height, arm circumference and triceps skinfold were measured and the sitting height ratio and muscle and body mass index, fat areas of the arm calculated. Prevalences of low weight-for-age (LW/A), low height-for-age (LH/A) and low weight-for-height (LW/H) were estimated using NHANES III. The socio-environmental variables were surveyed using semi-structured questioner. Prevalences of LH/A were similar in both populations and LW/A and LW/H higher in GA. The lower limb shortening was higher in SR, the deficits of muscle and adipose tissue in GA. It is concluded that whereas GA shows a higher prevalence of acute malnutrition associate to body composition changes as consequence of the social insecurity; in SR, is evident that nutritional status and life quality are better than GA surpassing those adverse conditions that affected the early stages of development as a mirror in body proportion change.
