南京市居民体力活动与2型糖尿病关系

目的 探讨江苏省南京市居民体力活动状况及与2型糖尿病(T2DM)发病的关系。方法 选取南京市的3个城区和2个乡村,调查年满35周岁并在当地居住满5年的常住人口5 978人,采用自行编制的《南京市慢病防制社区居民健康相关调查表》进行调查,收回有效调查表5 616份。结果 全市总的2型糖尿病现患率为4.6%,其中城区为6.9%,乡村为1.5%。与不太活动者相比,轻度、中度、重度体力活动者罹患2型糖尿病的风险分别降低24.5%,83.5%和73.0%。经多因素调整后,从事中度体力活动的人群糖尿病现患率仍明显低于不太活动者(调整OR值为0.280,95%CI=0.162~0.484)。结论 中等强度的体力活动可明显降低2型糖尿病发病危险,体力活动是2型糖尿病的保护因素。

Investigation of relationship between physical activity and type 2 diabetes mellitus

Objective To explore physical activity and its association with type 2 diabetes mellitus(T2DM)in Nanjing residents.Methods Population-based cross-sectional study was conducted on local residents older than 35 years in three urban districts and two rural counties.Results The overall prevalence of T2DM was 4.6%,and 6.9% in urban,1.5% rural area,respectively.Participants with light,moderate and vigorous-physical activity had significant lower risk of T2DM compared to inactivity population(OR=0.755,95%CI=0.570~0.974;OR=0.165,95%CI=0.105~0.260;OR=0.270,95%CI=0.146~0.499 for light,moder ate and vigorous respectively).After adjusting for possible confounding factors,adjusted odds ratio(Adj.OR)of T2DM was significantly lower in moder ate physical activit y population than in physical inactivity population(Adj1 OR=0.280,95%CI=0.162~0.484).Conclusion Moderate-intensity physical activity is associated with a significant reduction in risk for T2DM.
