摘要
目的 :探讨南京地区健康人群中体重指数 (BMI)、腰臀围比 (WHR)及腹围的流行病学分布状况。 方法 :对 344 5例长期居住南京地区的 18～ 90岁汉族健康成人的BMI、WHR及腹围进行流行病学调查 ,检测受检者身高、体重、腰围、腹围、臀围 ,分析BMI、WHR及腹围的性别及年龄分布。 结果 :南京地区健康人群总体的平均BMI为 (2 3.2 8± 3.4 9)kg/m2 ,其中男性为 (2 3.81± 3.36 )kg/m2 ,女性为 (2 2 .2 5± 3.4 9)kg/m2 ,经t检验有显著差异(t=12 .75 ,P <0 .0 0 1)。BMI≥ 2 5的人群比例为 30 .9% ,BMI≥ 30的为 3.4 %。BMI随年龄变化的曲线为抛物线 ,从 18～ 4 9岁 ,随着年龄的增长而显著升高 ,5 0岁以后升高趋势变缓 ,6 0～ 6 9岁达到最高峰 ,此后随着年龄的增高而开始略有下降 ;WHR及腹围随年龄变化的曲线则为斜线 ,随着年龄的增长而显著升高 ,5 0岁以后升高速度缓慢 ,但依然维持上升的趋势。 结论 :随着社会生活水平的提高 ,人群中BMI、WHR及腹围结构发生了明显的变化 ,肥胖者日趋增多 。
Objectives: To explore the epidemiological distribution of body mass index(BMI),waist to hip ratio(WHR) and abdominal circumference in population of Nanjing,Jiangsu Province. Methods: BMI, WHR and abdominal circumference were measured on 3 445 healthy cases aged 18～90 of Nanjing. Epidemiological distribution of BMI,WHR and abdominal circumference were analyzed according to sex and age. Results:The total mean BMI was( 23.28 ±3.49)kg/m 2, and the BMI in male was higher〔(23.80±3.36)kg/m 2〕 than that in female 〔(22.25± 3.49)kg/m 2〕( t =12.75, P <0.001).The proportion of the cases whose BMI≥25 was 30.9%,and the proportion of the cases whose BMI≥30 was 3.4 %. The BMI showed a gradual increase with the age growing up to forty nine, but a decline occurred subsequently in elder people. On the other hand, the WHR and abdominal circumference showed a steady increase with aging. Conclusions: As the living standard improved, the epidemiological distribution of BMI, WHR and abdominal circumference have changed a lot,and a new diagnostic criterion to define obesity should be established.
