To study anthropometrical and body composition variables as predictors of risk for metabolic alterations and metabolic syndrome in female adolescents.
Biochemical, clinical and corporal composition data of 100 adolescents from 14 to 17 years old, who attended public schools in Viçosa, Southeastern Brazil, were collected.
Regarding nutritional status, 83, 11 and 6% showed eutrophia, overweight/obesity and low weight, respectively, and 61% presented high body fat percent. Total cholesterol presented the highest percentage of inadequacy (57%), followed by high-density lipoprotein (HDL - 50%), low-density lipoprotein (LDL - 47%) and triacylglycerol (22%). Inadequacy was observed in 11, 9, 3 and 4% in relation to insulin resistance, fasting insulin, blood pressure and glycemia, respectively. The highest values of the fasting insulin and the Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) were verified at the highest quartiles of body mass index (BMI), waist perimeter, waist-to-height ratio and body fat percent. Body mass index, waist perimeter, and waist-to-height ratio were the better predictors for high levels of HOMA-IR, blood glucose and fasting insulin. Waist-to-hip ratio was associated to arterial hypertension diagnosis. All body composition variables were effective in metabolic syndrome diagnosis.
Waist perimeter, BMI and waist-to-height ratio showed to be good predictors for metabolic alterations in female adolescents and then should be used together for the nutritional assessment in this age range.
研究人体测量学和身体成分变量作为女性青少年代谢改变和代谢综合征风险预测指标的情况。
收集了巴西东南部维索萨市公立学校100名14至17岁青少年的生化、临床和身体成分数据。
在营养状况方面，分别有83%、11%和6%的青少年营养正常、超重/肥胖和体重过低，61%的青少年体脂百分比偏高。总胆固醇不足的比例最高（57%），其次是高密度脂蛋白（HDL - 50%）、低密度脂蛋白（LDL - 47%）和甘油三酯（22%）。胰岛素抵抗、空腹胰岛素、血压和血糖的不足比例分别为11%、9%、3%和4%。在体重指数（BMI）、腰围、腰高比和体脂百分比的最高四分位数处，空腹胰岛素和稳态模型评估胰岛素抵抗（HOMA - IR）的值最高。BMI、腰围和腰高比是HOMA - IR、血糖和空腹胰岛素高水平的较好预测指标。腰臀比与动脉高血压诊断相关。所有身体成分变量在代谢综合征诊断中均有效。
腰围、BMI和腰高比是女性青少年代谢改变的良好预测指标，因此应在该年龄范围内一起用于营养评估。
