江苏省成年人肥胖测量指标与糖尿病患病风险的关系

目的 探讨江苏省成年人肥胖测量指标与糖尿病患病关系.方法 采用多阶段整群随机抽样方法,在江苏省14个成人慢性病及其危险因素监测点随机抽取8 400名≥18岁常住居民进行问卷调查、体格检查和实验室检测.运用非条件logistic回归方法,分析肥胖、中心型肥胖、体质指数（BMI）、腰围和腰身比等肥胖测量指标与糖尿病患病关系.结果 江苏省成年人糖尿病患病率为8.5％,肥胖率为13.6％,中心型肥胖率为30.8％.不同年龄组居民糖尿病患病分布差异有统计学意义（χ^2=119.77,P＜0.05）,且患病率随年龄的增长呈上升趋势.肥胖、中心型肥胖、BMI、腰围和腰身比均与糖尿病患病显著相关（χ^2=39.01、86.82、95.11、114.61、119.76,均P＜0.05）,且随着BMI、腰围和腰身比的增加,糖尿病的患病风险也不断升高;BMI、腰围和腰身比每增加1个测量单位,糖尿病患病风险相应升高13％（OR=1.13,95％CI：1.10～1.15）、5％（OR=1.05,95％CI：1.04～1.06）和8％（OR=1.08,95％CI：1.07～1.10）;腰身比、腰围和BMI每增加1个标准差（SD）,糖尿病患病风险分别增加62％（OR=1.62,95％ CI：1.49～1.76）、61％（OR=1.61,95％CI：1.48～1.75）和49％ （OR=1.49,95％CI：1.38～1.62）,BMI、腰围和腰身比对糖尿病患病风险的影响依次升高. 结论 BMI、腰围和腰身比与糖尿病患病密切相关.肥胖是糖尿病患病的重要影响因素,糖尿病患病风险随肥胖程度的增加而升高.

Relationship between the measures of adiposity and the prevalence of diabetes mellitus in adults in Jiangsu province

Objective To explore the relationship between the measures of adiposity and the prevalence of diabetes mellitus in adults of Jiangsu province.Methods Total of 8 400 inhabitants aged 18 years and above were selected from 14 chronic no-communicable diseases surveillance areas by multi-stage cluster random sampling method in Jiangsu province.Information of the inhabitants was collected with a questionnaire survey,anthropometric measurement and biochemical test of blood.Data was analyzed to explore the relationship between obesity,central obesity,the measures of adiposity including weight,body mass index（BMI）,waist circumference,waist-height ratio and the prevalence of diabetes mellitus by unconditional logistic regression analysis.Results The prevalence of diabetes mellitus,obesity and central obesity was 8.5%,13.6%,30.8% respectively in adults of Jiangsu province.The distributional difference of the prevalence of diabetes mellitus in different age groups was statistically significant （χ^2=119.77,P〈0.05）.The prevalence showed an obvious rising trend with age growth.The results of unconditional logistic regression analysis showed that obesity,central obesity,weight,BMI,waist circumference and waist-height ratio were associated with diabetes mellitus（χ^2=39.01,86.82,95.11,114.61,119.76,all P〈0.05）.The risk of diabetes mellitus was rising with the increase of BMI,waist circumference and waist-height ratio.About 1-unit greater measures of BMI,waist circumference and waist-height ratio were respectively associated with 13% （OR=1.13,95%CI：1.10-1.15）,5% （OR=1.05,95%CI：1.04-1.06） and 8% （OR=1.08,95%CI：1.07-1.10） higher risk of diabetes mellitus.And about 1-SD greater measures of waistheight ratio,waist circumference and BMI were respectively associated with 62% （OR=1.62,95%CI：1.49-1.76）,61% （OR=1.61,95% CI：1.48-1.75） and 49% （OR=1.49,95%CI：1.38-1.62） higher risk of diabetes mellitus.The risk of diabetes mellitus increased in turn with the influence of BMI,waist circumfer
