目的　探讨天津市城区社区人群体重与糖耐量低减 (IGT)患病率关系 ,为预防与控制IGT提供科学依据。方法　采用整群随机抽样方法 ,对抽取到的社区居民共 6 2 5 77人 (男 30 46 2人 ,女 32 115人 )进行IGT流行病学现况调查、临床体检及血糖检测等的统计分析。结果　社区整个人群的IGT患病率男、女及合计分别为 13.13‰、19.18‰及 16 .2 3‰ ;不同体重人群组的IGT患病率不同 ,并随体重增加而不断升高 ,此种趋势在男、女中是一致的。结论　证明IGT发生与体重、超重和肥胖之间存在密切的关联。因此 ,必须提倡合理膳食、加强体育锻练等积极措施 ,才能降低IGT患病率 ,进而有效地预防与控制糖尿病及心血管疾病 Objective To investigate the relationship between body weight and prevalence of impaired glucose tolerance (IGT) in urban communities in Tianjin and to provide a scientific basis for the prevention and control of IGT. Methods A cluster random sampling method was used to investigate the prevalence of IGT epidemiology, clinical examination and blood glucose among 6 25,777 (30,662 men and 32,153 women) community residents. . Results The prevalence of IGT in the whole community was 13.13 ‰, 19.18 ‰ and 16.23 ‰, respectively. The prevalence of IGT in different weight groups was different and increased with weight gain. The trend in men and women are the same. Conclusions Proves that there is a close relationship between the occurrence of IGT and weight, overweight and obesity. Therefore, we must advocate reasonable diet, physical activity and other positive measures to strengthen, in order to reduce the prevalence of IGT, and thus effective prevention and control of diabetes and cardiovascular disease
