社区居民超重、肥胖与糖尿病患病率的关系

目的了解不同体重指数、腰围与糖尿病患病率的关系,为社区居民的糖尿病的早期干预提供理论依据。方法采用分层整群抽样方法抽取40岁及以上的常住居民4752人进行调查,测量身高、体重、腰围,测定空腹口服75g葡萄糖后2h血糖。结果本次共调查40岁以上居民4752人,查出DM患者220人,患病率为4.63%,其中男性4.35%,女性4.86%;查出IGT患者282人,患病率为5.93%,其中男性7.48%,女性4.67%,性别患病率未见显著性差异(P0.05)。除40~岁组以外,其他年龄组随着BMI水平增高,DM、IGT患病率也明显上升(P0.05);除BMI18.5组外,DM、IGT患病率与年龄增长密切相关(P0.05)。男女各年龄组腹型肥胖的DM、IGT患病率比正常体型组的明显增加(P0.05)。结论 BMI≥24或男性WC≥85cm、女性WC≥80cm者是DM患病高危人群,因此做好中老年肥胖人群的行为干预是预防糖尿病的有效措施。

The Relationship between Body Mass Index and Waistline and the Prevalence of Diabetes Mellitus in Community Residents

Objective To investigate the relationship between body mass index （BMI）, waist circumference （WC） and the prevalence of diabetes mellitus（DM）,and to provide theory guidance for diabetes early intervention in community residents. Methods To sample 4752 cases constant residents by stratified cluster sampling, age from 40 years to up 40 years, then measured their height, weight, waistline, and blood sugar after oral administration on an empty stomach 75g glucose two hours. Results There were 220 cases DM patients among 4752 residents, the prevalence of DM was 4.63%, male 4.35%, female 4.86% ; There were 282 cases impaired glucose tolerance （IGT）patients, the prevalence of IGT was 5.93% ,male 7.48% ,female 4.67% ,there was no significant difference between male and female DM and IGT prevalence （P〉0.05）. Except the group of 40-years, the prevalence of DM and IGT was obviously increased accompanying by higher BMI level in other groups（P〈0.05）;There was a close correlation between the prevalence of DM and IGT and elder age in all other groups except BMI〈IS.5 group（P〈0.05） ;Abdomen-type obesity group had a higher prevalence of DM and IGT than normal type of figure group in different age and gender groups（P〈0.05 ）. Conclusion The people with BMI ≥ 24 or male WC ≥ 85cm, female WC≥ 80cm were high-risk group of DM, so developing behavior intervention in middle-age and old people was an effective measure for preventing diabetes mellitus.
