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20 000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%vs 4.94%,P<0.01);男性空腹血糖异常的比例也明显比女性多(8.89%vs 3.72%,P<0.01);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<0.01),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 analyze the distribution of fasting blood glucose in adults by analyzing the data of fasting blood glucose among different sexes and different age groups in Chongqing. METHODS: From January 1, 2009 to October 31, 2009, a stratified cluster sampling method was used across the city to randomly enroll 20 000 people aged 19-60 years. By age group is divided into: 18 to 29 years old group, 30 to 39 years old group, 40 to 49 years old group and 50 to 59 years old group; Divided by sex groups: male group and female group; And non-main city group. Fasting blood glucose levels were measured on all subjects. Results: Compared with non-urban residents, the proportion of people with abnormal fasting blood glucose in the main urban areas was decreased (13.35% vs 4.94%, P <0.01), and the proportion of men with fasting blood glucose was significantly higher than that of women (8.89% vs 3.72 %, P <0.01). There was also a significant difference in the proportion of fasting blood glucose among all age groups (P <0.01). With the increase of age, the proportion of fasting blood glucose was also increased. CONCLUSION: The different place of residence, sex and age have a significant effect on fasting blood glucose level in Chongqing population aged 19-60 years. The fasting blood glucose level of middle-aged male population in non-main urban area increases obviously.
