Mild stunting is associated with higher body fat: study of a low-income population.

OBJECTIVE To test if individuals having height-for-age z scores between -2 and -1 present higher body fat percentage and, therefore, should not be categorized as having normal nutritional status. METHODS The study involved 96 individuals (52 boys and 44 girls); 57% of whom had already attained puberty. Body composition was analyzed by dual energy X-ray absorptiometry. RESULTS The percentage of abdominal body fat in pre-pubertal stunted girls was higher (27.4%; p = 0.01) in comparison with their non-stunted counterparts (20.6%). Similar differences in abdominal fat content (%) were observed for pubertal stunted and non-stunted girls and boys (37.6 and 29.8%, respectively, p = 0.01; 24.6 and 15.7%, p = 0.01, respectively). The percentages of total body fat percent in pre-pubertal stunted girls and pubertal stunted boys (29.9 and 24.5%, p = 0.03; 26.3 and 18.1%, p = 0.01, respectively) were higher than those of their non-stunted counterparts. Non-stunted groups showed lower waist circumferences. CONCLUSION Adolescents with mild stunting exhibit alterations in body composition indicating increased risk of metabolic diseases.
