摘　　要：早期研究证明,在成人增龄过程中,体脂分布会从四周逐渐转移到躯干,而躯干脂肪,尤其是内脏脂肪的增加与代谢紊乱密切相关。目的：构建20～69岁天津男性体质指数和腰臀脂肪比之间的最优模型;探索20～69岁天津男性增龄过程中体质指数和腰臀脂肪比的肥胖敏感期。方法：2011年1月至2013年12月募集符合纳入标准的20～69岁天津男性8 036名,测量身体成分及肥胖相关形态学指标,曲线拟合体质指数和腰臀脂肪比,并确定2变量最优回归模型,探讨成年男性增龄过程中的肥胖敏感期。结果：（1）1～6次曲线的AIC值和R有显著差异,分别为（-24 001.93、0.849）、（-24 265.13、0.854）、（-24 263.17、0.860）、（-24 289.44、0.866）、（-24 299.97、0.866）和（-24 298.51、0.860）;（2）20～69岁男性体质指数增量峰值出现于20～24岁至25～29岁、35～39岁至40～44岁、50～54岁至55～59岁、60～64岁至65～69岁,谷值出现于30～34岁至35～39岁、45～49岁至50～54岁;腰臀脂肪比增量峰值出现于20～24岁至25～29岁、35～39岁至40～44岁、60～64岁至65～69岁,谷值出现于30～34岁至35～39岁、45～49岁至50～54岁;（3）回归拟合模型的判别系数大于0.7。结论：（1）5次曲线为20～69岁天津成年男性体质指数和腰臀脂肪比拟合关系最优模型;（2）天津成年男性体质指数和腰臀脂肪比增量的阶段性变化提示,增龄过程中存在肥胖的阶段性敏感年龄,是体力活动及临床医学干预的关键时期。Early studies have shown that, during the adult aging process, body fat distribution will gradually shift from limbs to trunk. Truncal fat, especially increased visceral fat is associated with metabolic disorders. Objective： To build the best curve model between BMI and waist-hip-fat ratio （WHFR） among Tianjin males aged 20-69 years old; Explore the obesity sensitive periods of BMI and WHFR among subjects. Methods： The subjects were 8 036 males aged 20 to 69 years who were test by Tianjin Municipality Physical Fitness Surveillance Center from January, 2011 to December, 2013. The test indexes included body fat mass, muscle mass, skeletal muscle mass, WHFR, fat-free mass, height and body weight. Curve fitting was applied to the relationship between BMI and WHFR, and the optimal model between BMI and WHFR was established according to the values of A1C and R. The obesity sensitive periods were anglicized according to the annual incremental values. Results： （1） First to sixth order polynomials were valid in all ages, and AIC and R were-24 001.93, 0.849;-24 265.13, 0.854;-24 263.17, 0.860;-24 289.44, 0.866;-24 299.97, 0.866; and-24 298.51, 0.860, respectively. （2）Annual incremental peaks of BMI among males were in 20～24 years ～ 25～29 years, 35～39 years ～ 40～44 years, 50～54 years - 55-59 years, 60-64 years - 65～69 years, while valley values appeared in 30-34 years ～ 35～39 years, 45～49 years - 50～54 years. Annual incremental peaks of WHFR were in 20-24 years - 25～29 years, 35-39 years- 40～44 years, 60～64 years ～ 65～69 years, respectively, while valley values appeared in 30～34 years-35-39 years, 45-49 years ～ 50- 54years, respectively. Conclusions： （1） The fifth order curve fitting for males was confirmed as the best curve model between BMI and WHFR during 20～69 years old. （2） Incremental changes with age of BMI and WHFR among males suggested there were sensitive periods for obesity, which were crucial periods for physical activity and clinical interventi
