摘　　要：目的 描述中国慢性病前瞻性研究（CKB）项目10个地区人群超重/肥胖现状的地区差异.方法 CKB项目于2004-2008年在城市和农村各5个地区募集30 ～79岁队列成员并完成基线调查,剔除BMI异常个体后,分析10个地区中512 489名队列成员基线调查时的BMI和WC及其对应的超重/肥胖和中心性肥胖分组情况的地区差异.结果 10个地区女性的超重/肥胖（45.3％）和中心性肥胖（44.6％）水平均高于男性（41.7％和38.3％）.青岛项目点人群的超重/肥胖率（男性为66.9％,女性为67.5％）和中心性肥胖率（男性为63.3％,女性为64.9％）均为最高.超重/肥胖的地区差异在男性中更为明显;除河南以外的农村项目点超重/肥胖率相对较低.在BMI＜24.0 kg/m2的非超重/肥胖人群中,部分个体达到中心性肥胖标准（男性为9.8％,女性为15.3％）;该比例在青岛项目点更高（男性为22.2％,女性为23.2％）.结论 CKB项目10个地区研究人群的超重/肥胖情况存在明显的地区差异.Objective To describe gender and regional differences in the prevalence of overweight/obesity in adults found by China Kadoorie Biobank （CKB） study, involving 512 489 adults, in 10 areas in China.Methods The baseline survey of CKB was conducted in 5 urban areas and 5 rural areas in China during 2004-2008.After excluding those with extreme value of BMI （〈 15.0 kg/m2 or 〉50 kg/m2） , 512 489 subjects were included in the analysis.Overweight/obesity was classified according to BMI and WC, and diagnosed according to the guideline for prevention and control of overweight/obesity in Chinese adults.The gender and regional specific distributions of overweight/obesity were compared after adjusting for age.Results The overall prevalence of overweight/obesity was higher in females （45.3%） than in males （41.7%） , and the prevalence of central obesity was also higher in females （44.6%） than in males （38.3%）.Both the prevalence of overweight/obesity （66.9% in males and 67.5% in females） and the central obesity （63.3% in males and 64.9% in females） were highest in Qingdao.The area specific difference in the prevalence was more obvious in males than in females.Rural areas all had the low prevalence except Henan.Moreover, central obesity was diagnosed in some subjects （15.3% in females, 9.8% in males） with normal/low BMI （〈24.0 kg/m2）.This phenomenon was more obvious in Qingdao （22.2% in males and 23.2% in females）.Conclusion The prevalence of overweight/obesity in adults varied greatly across different areas in China.
