【目的】探讨糖耐量正常（NGT ）的腹型肥胖中青年男性糖耐量试验变化与体成分的关系。【方法】选择2009年在本院体检中心进行体检的67例NGT 成年男性，年龄20～50岁，根据腰围（WC）将其分为两组：WC正常成年男性组（对照组，n ＝31），腹型肥胖成年男性组（研究组，n ＝36）。两组研究对象均进行口服葡萄糖耐量试验（OGTT），并检测其空腹血糖（FPG），糖负荷后0．5 h血糖（0．5hPG）、1hPG、2hPG、3hPG。应用双能X线骨密度仪进行体成分分析。【结果】两组间FPG、2hPG、3hPG比较无统计学差异（ P ＞0．05），研究组0．5hPG ，1hPG和葡萄糖曲线下面积（AUCglu ）高于对照组（ P ＜0．05）。体质量指数（BMI），WC及各部位脂肪质量与FPG及3hPG无相关性（ P ＞0．05）；0．5hPG、2hPG与总体脂肪质量及躯干脂肪质量存在正相关（ P ＜0．05）。1hPG 及AUCglu与BMI ，WC ，总体脂肪质量，四肢脂肪质量，躯干脂肪质量均呈正相关（ P＜0．01）。【结论】糖耐量正常腹型肥胖中青年男性已存在糖负荷后血糖代谢异常，与BMI和WC相比，体脂成分分析更能有效识别肥胖男性早期糖代谢异常。“,”[Objective] To explore the relationship between the changes of oral glucose tolerance test and body composition in young and middle‐age abdominal obese males with normal glucose tolerance (NGT ) .[Methods] This case‐control study included 36 abdominal obese males (waist circumference ,WC≥90 cm) and 31 non‐abdominal obese males (WC0 .05) .0 .5 ,1‐hour postload plasma glucose (1hPG) and glucose area under the curve (AUCglu ) were higher in abdominal obese group than those in control group ( P<0 .05) .AUCglu was positively correlated with body mass index ( r =0 .390) ,WC ( r =0 .438) ,total body fat content ( r =0 .445) ,limbs fat content ( r =0 .372) and trunk fat content ( r =0 .475)( P <0 .01) .According to multiple regression analysis ,trunk fat content was an independent predictor for AUCglu (β=3 .332 ,P=0 .000 ,R2 =0 .228) .[Conclusion] The changes of postload plasma glucose occur in young and middle‐age abdominal obese males with NGT .Body composition assessment is a valid and more ac‐curate method than BMI and WC for predicting early changes of glucose metabolism .
