目的对2005年贵州省贵阳市城镇及乡村20～69岁居民有腹型肥胖状况进行检测分析。方法采集贵阳市2005年20～69岁人群的腰围和臀围数据,计算腰臀比、腹型肥胖率、腰围及腰臀比均值。结果贵阳市男性25～29岁、女性40～44岁年龄组腹型肥胖率增长幅度最大;男性60～64岁、女性65～69岁年龄组腹型肥胖率最高,达58.22%,86.36%;45～69岁女性腹型肥胖率显著高于男性(P<0.01)。与贵州省贵阳市2000年相比,男女腰臀比均值及男性部分年龄组、女性各年龄组匀值明显增大(P<0.05,P<0.01);女性腰围比贵州省2000年增大3.01～6.65cm(P<0.01),男性腰围低于2005年全国均值2.14～3.95cm(P<0.01),女性腰围高于全国均值1.48～4.56cm(P<0.01)。结论贵阳市男女性25岁起应注意监控腰围及腰臀比,女性进入40岁后腹型肥胖人数比例相对偏高。 Objective To analyze the status of abdominal obesity among urban residents aged 20-69 years in urban and rural areas of Guiyang, Guizhou Province in 2005. Methods The data of waist circumference and hip circumference of 20 ~ 69 years old population in 2005 in Guiyang City were collected to calculate the average of waist - hip ratio, abdominal obesity rate, waist circumference and waist - to - hip ratio. Results The incidence of abdominal obesity in males aged 25- 29 years and in females 40-44 years was the highest. The obesity rate was 58.22% and 86.36% in males aged 60-64 years and females aged 65-69 years. The abdominal obesity rates in 45-69 years old women were significantly higher than those in men (P <0.01). Compared with 2000 in Guiyang City, Guizhou Province, the mean value of waist-hip ratio of men and women and part of age groups of men and women were significantly increased (P <0.05, P <0.01), and waist circumference of women was 3.01 ~ 6.65cm (P <0.01). The waist circumference of male was lower than the national average of 2.14 ~ 3.95cm in 2005 (P <0.01). The waistline of female was higher than the national average of 1.48 ~ 4.56cm (P <0.01).
