重庆市成人居民空腹血糖水平分布情况

Distribution of fasting glucose levels of adult residents in Chongqing

目的：通过分析重庆市不同性别和不同年龄层次人群的空腹血糖数据，了解成人居民空腹血糖水平的分布特点。方法：2009月1月1日～2009年10月31日在全市范围内采用整群分层抽样的方法随机纳入20000人，年龄在19～60岁。按年龄分组分为：18．29岁组、30～39岁组、40～49岁组和50～59岁组；按性别分组分为：男性组和女性组；按居住地分为主城区组和非主城区组。对所有调查对象进行空腹血糖水平的测量。结果：与非主城区人群比较，主城区居住的人群空腹血糖异常的比例有所降低（13．35％vs4．94％，P〈O．01）；男性空腹血糖异常的比例也明显比女性多（8．89％VS3．72％，P〈O．01）；各年龄段之间空腹血糖异常的比例差异也有显著性差异（P〈O．01），随着年龄的增加，空腹血糖异常的比例也随之增加。结论：不同居住地点，性别和年龄对重庆19—60岁人群的空腹血糖水平有明显的影响，其中非主城区中年男性人群的空腹血糖水平增大明显。

Objective： To study the distribution of blood glucose among adult residents in Chongqing through analysis of the health data of different gender and age groups.Methods：From January. 1 st, 2009 to October 31,2009, a cluster stratified sampling method was adopted, including 20 000 people aged 19 to 60 years in Chongqing. Subjects were divided into 4 groups by age： 18-29 years of age, 30-39 years of age, 40-49 years of age, and 50-59 years of age ; 2 groups by sex ： male group and female group ; 2 groups by place of residence ： urban areas and non-urban areas.Fasting blood glucose was measured. Results：Compared with non-urban areas population, the proportion of impaired fasting glucose decreased significantly in urban areas （ 13.35% vs 4.94%, P〈0.O1 ） ; the proportion of impaired fasting glucose in males was significantly higher than in females （ 8.89% vs 3.72%, P〈0.01 ） ; the proportions of impaired fasting glucose were signif- icantly different among four age groups （ P〈0.01 ） the proportion of. impaired fasting glucose increases with age growing. Conclusion： The residence area, gender and age have significant impact on impaired fasting glucose in Chongqing adult population, and middle-aged men of non-urban areas have significantly increasing level of fasting blood glucose.
