摘要
目的了解2010年我国成年人超重和肥胖流行状况。方法2010年在我国内地31个省（市、自治区）的162个监测点，采用多阶段分层整群随机抽样方法调查了98271名18岁以上居民，测量调查对象的体重和身高，并计算了BMI。以24kg／m^2≤BMI〈28kg／m^2为超重，BMI≥28kg／m^2为肥胖。经复杂加权后，计算了我国不同性别、年龄、区域成年人的超重率、肥胖率、超重和肥胖总率。结果我国成年人超重率为30．6％，男性和女性分别为31．5％、29．7％（x^2=16．05，P〈0．01），18～44、45～59和≥60岁年龄组分别为27．1％、37．2％、32．3％（x^2=482．00，P〈0．01），城市和农村分别为33．9％、29．1％（X。=21．14，P〈0．01），东、中、西部分别为32．O％、31．1％、28．0％（x^2=8．72，P〈0．05）；肥胖率为12．0％，男性和女性分别为11．9％、12．1％（X。=0．33，P〉0．05），18～44、45～59和／〉60岁年龄组分别为10．6％、14．7％、12．6％（X。=111．25，P〈0．01），城市和农村分别为14．2％、11．O％（x^2=12．11，P〈0．01），东、中、西部地区分别为13．5％、11．9％、9．9％（X^2=10．05，P〈0．01）；超重和肥胖总率为42．6％。超重和肥胖总率呈现城市（48．1％）高于农村（40．1％）（√=20．37，P〈0．01），东（45．5％）、中（43．0％）、西（37．9％）部地区依次降低的趋势（X。=10．46，P〈0．01）。结论2010年我国成年人超重率、肥胖率、超重和肥胖总率较高，且存在性别、年龄、城乡和地区差异。
Objective To study the prevalence and characteristics of overweight and obesity among Chinese adults aged 18 and above, in year 2010. Methods A total of 98 271 aduhs aged 18 and above, who were sampled from 162 surveillance points of 31 provinces of China mainland, were enrolled in the study. Weight and height of each subject were measured, and then body mass index （BMI） was calculated. Overweight was defined as 24 kg/m^2≥ BMI 〈 28 kg/ma, while obesity was defined as BMI I〉 28 kg/m^2. After complex weighting, the prevalence of overweight and obesity among total population and specified rates among different populations by gender and districts and age were calculated. Results Prevalence rate of overweight among Chinese adults was 30. 6% , separately at 31.5% and 29.7% among males and females （X^2 = 16. 05 ,P 〈 0. 01 ） ; 27. 1% , 37.2% and 32. 3% in groups of population aged 18-44, 45 -59 and over 60 year-old, respectively （X^2 = 482. 00,P 〈 0.01 ）; separately at 33.9% and 29. 1% in urban and rural areas （X^2 =21.14,P〈0.01）; 32. 0%, 31.1% and 28. 0% in eastern, central and western regions, respectively （ X^2 = 8.72,P 〈 0, 05 ）. Prevalence rate of obesity among Chinese adults was 12. 0% , separately at 11.9% and 12. 1% among males and females （ X^2=0. 33, P 〉 0. 05 ） ; and 10.6%, 14.7% and 12. 6% in groups of populations aged 18 -44, 45 -59 and over 60 year-old, respectively （X^2 = 111.25,P 〈 0. 01 ） ; separately at 14. 2% and ll. 0% in urban and rural areas （ X^2 = 12. 11 ,P 〈 0. 01 ） ; and 13.5% , ll. 9% and 9. 9% in eastern, central and western regions, respectively （ X^2 = 10. 05, P 〈 0. 01 ）. The total prevalence rate of overweight and obesity among Chinese aduhs was 42. 6%. It appeared that the total prevalence rate of overweight and obesity among urban populations（48. 1% ） were higher than rural populations（40. 1% ） （X^2 =20. 37 ,P 〈0. 01 ） ; while the total rate showed a gradual decreasing trend from eastern（45.5% ） to central（43.0% ） and western（37. 9% ） regions（ X^2 = 10.46,P 〈 0. 01 ）. Conclusion The prevalence of overweight and obesity were comparatively high among Chinese adults aged 18 and above in year 2010, and significant differences could be found among gender, age, urban or rural areas and eastern, central or western districts.
