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.
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.
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.
Adolescents with mild stunting exhibit alterations in body composition indicating increased risk of metabolic diseases.
检验身高-年龄 Z 评分在-2 至-1 之间的个体是否具有更高的体脂肪百分比，因此不应被归类为具有正常营养状态。
本研究纳入了 96 名个体（52 名男孩和 44 名女孩）；其中 57%已经进入青春期。通过双能 X 射线吸收法分析身体成分。
与非矮小的青春期前矮小女孩相比，矮小女孩的腹部体脂肪百分比更高（27.4%；p = 0.01）。青春期前和青春期的矮小和非矮小女孩和男孩的腹部脂肪含量（%）也存在类似的差异（分别为 37.6 和 29.8%，p = 0.01；24.6 和 15.7%，p = 0.01）。青春期前矮小女孩和青春期前矮小男孩的体脂肪百分比（29.9%和 24.5%，p = 0.03；26.3%和 18.1%，p = 0.01）高于非矮小组。非矮小组的腰围更小。
轻度发育迟缓的青少年表现出身体成分的改变，表明其患代谢性疾病的风险增加。
