Abstract
An adequate evaluation of nutritional status must consider weight for height (W/H) and also lean and fat body mass. The influence of environmental factors such as nutrition and physical activities upon lean and fat development is well known. A positive correlation between physical and nutrient intake with SEL has been described. We were interested in studying the influence of the socioeconomic level upon lean and fat body mass of schoolage children in different puberal stages with and without weight deficit. Fran a sample of 6234 schoolage children of both sexes, aged between 6 to 16 years, 3061 adolescents in II to V stage of puberal development were selected. Height for age (H/A), W/H, lean and fat arm mass (LAM and FAM) were evaluated according to NCHS tables; SEL according to Modified Graffar scale and breast and genital development according to Tanner stages. It was considered a normal body weight when W/H is between 90 to 110%, body weight deficit below 90% and body weight excess over 110%. There were differences in LAM and FAM according to SEL in early and late puberal stage in underweight boys. Overweight boys had differences in LAM according to SEL. Underweight girls had differences in LAM and FAM according to SEL, overweight girls had differences only in LAM according SEL. An increased percentage of lean mass in upper SEL either in over or underweight adolescents was found in both sexes. The possible etiologies of these results are discussed.
