摘要
目的 探讨中国成人体重指数 (BMI)和腰臀围比值 (WHR)的分布特征。方法 从 1994年全国糖尿病防治协作组资料库中选取 16 35 4例具有完整口服葡萄糖耐量试验 (OGTT)资料的中国成人 (≥ 2 5岁 ) ,按不同性别、不同年龄段 (2 5～ 34岁 ,35～ 5 4岁 ,5 5～ 6 4岁 ,≥ 6 5岁 )、不同血糖水平和不同纬度地区 (北部、中部和南部 )分组进行统计分析。结果 总体人群男女两性的BMI均为 2 4 3kg/m2 ,以不同年龄段分成 4组 ,不同性别的BMI和WHR均随年龄的增加而增加。其中糖耐量正常(NGT)人群的变化与总体人群相同 ,但均值较总体人群低 (P <0 0 5 ) ,男女两性的BMI均为 2 3 6kg/m2 。总体人群从北到南随纬度的降低 ,各地区相应年龄组的BMI均逐渐下降 (P <0 0 1) ,而WHR则呈相反变化。男女两性各自的变化相同。不同地区中NGT、糖耐量低减 (IGT)和新诊断糖尿病(DM)人群BMI和WHR的变化也与总体人群相同 ,同地区中 ,BMI和WHR均随血糖的升高而显著增加 (P <0 0 1)。自北到南BMI <2 5kg/m2 人数所占比例明显升高 (49 8% ,5 6 8% ,6 8 7% ) ,BMI≥ 2 5kg/m2 和BMI≥ 2 7kg/m2 则明显降低 (P <0 0 5 )。结论 中国成人BMI和WHR均随年龄的增加、血糖的升高而增加 ;BMI从北到南随纬度的降低而下降 ,WHR则增加。
Objective To investigate the distribution of body mass index (BMI) and waist hip ratio (WHR) in Chinese adults Methods 16 354 subjects (≥25 years)with complete oral glucose tolerance test (OGTT) data were selected from the database of the National Diabetes Prevention and Control Cooperative Group (1994) and were divided into groups according to sex, age(25～34 years, 35～54 years, 55～ 64 years, ≥65 years), blood glucose and latitude of areas The distribution of BMI and WHR was analyzed Results (1) In the overall population, the mean BMI of both sexes was the same (24 3 kg/m 2) WHR of male is 0 89 and female 0 86 Among the four age groups, BMI and WHR of male and female increased with age (2) The changes of BMI and WHR of different sex and age groups in normal glucose tolerance (NGT) were similar to the overall population, but the mean levels in the former were lower than those in the latter ( P <0 05) BMI of both sexes in NGT was the same (23 6 kg/m 2) WHR of male is 0 88 and female 0 85 (3) BMI in different age groups decreased gradually from north to south, for the 25～34 year group it was 24 1, 23 5 and 22 3 kg/m 2; for the 35～54 year group 25 5, 24 7 and 23 7 kg/m 2; for the 55～64 years group 25 5, 25 1 and 23 9 kg/m 2; for the ≥65 year group 25 5, 24 3 and 23 4 kg/m 2 ( P <0 01), whereas WHR increased from north to south The changes of BMI and WHR in both sexes were also similar (4) From the north to south, the percentage of people with BMI<25 kg/m 2 was 49 8%, 56 8%and 68 7%; BMI≥25 kg/m 2 50 2%, 43 2% and 31 3%; BMI≥27 kg/m 2 30 0%, 23 0% and 13 7% There were significant differences among the groups ( P <0 05) (5) The changes of BMI and WHR of NGT, impaired glucose tolerance (IGT) and newly diagnosed diabetes in the different areas were similar to the overall population The BMI and WHR increased significantly with blood glucose in the same area ( P <0 01) Conclusion The mean BMI of both men and women is 24 3 kg/m 2 in Chinese adults WHR of the male is 0 89 and female is 0 86 In NGT, BMI of both sexes is 23 6 kg/m 2 WHR of male is 0 88 and female 0 85 BMI and WHR go up with the increase of blood glucose and age BMI decreases along with the declining of latitude, but WHR presents an opposite trend of change
