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.
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/m(2) or >50 kg/m(2)), 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.
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/m(2)). This phenomenon was more obvious in Qingdao (22.2% in males and 23.2% in females).
The prevalence of overweight/obesity in adults varied greatly across different areas in China.
描述中国嘉道理生物样本库（CKB）研究在中国10个地区512489名成年人中发现的超重/肥胖患病率的性别和地区差异。
CKB的基线调查于2004年至2008年在中国的5个城市地区和5个农村地区进行。在排除体重指数（BMI）极值（<15.0kg/m²或>50kg/m²）的人群后，512489名受试者纳入分析。根据BMI和腰围对超重/肥胖进行分类，并按照中国成年人超重/肥胖防治指南进行诊断。在调整年龄后，比较超重/肥胖的性别和地区特异性分布。
超重/肥胖的总体患病率女性（45.3%）高于男性（41.7%），中心性肥胖患病率女性（44.6%）也高于男性（38.3%）。超重/肥胖患病率（男性为66.9%，女性为67.5%）和中心性肥胖患病率（男性为63.3%，女性为64.9%）在青岛均最高。男性患病率的地区特异性差异比女性更明显。除河南外，农村地区患病率均较低。此外，一些BMI正常/较低（<24.0kg/m²）的受试者被诊断为中心性肥胖（女性为15.3%，男性为9.8%）。这种现象在青岛更为明显（男性为22.2%，女性为23.2%）。
中国成年人超重/肥胖患病率在不同地区差异很大。
