The relationship between siting and watching television time and impaired glucose regulation,type 2 diabetes mellitus in Chongqing

目的探讨重庆市居民每周静坐看电视时间与糖调节受损（IGR）、2型糖尿病（T2DM）发生的关系。方法采用横断面研究，研究对象来自重庆市市区，年龄大于或等于40周岁，在当地居住满5年的常住人员共5719人，其中男2419人（42．3％），女3300人（57．7％），平均年龄（62．1±15．1）岁。结果全市总的IGR、T2DM现患率分别为6．3％、5．6％。重庆市居民每周静坐看电视时间平均为（12．3±10．1）h。经多因素调整后，每周静坐看电视时间大于14h人群，IGR、T2DM的现患率仍显著高于小于或等于7h者（调整OR值分别为：OR=1．528，95％CI=1.034～2．121；OR—1．482，95％CI=1．133～2．047）。结论静坐看电视时间与罹患IGR、T2DM的危险性呈正相关，因此，应积极鼓励和宣扬减少静坐时间，积极运动的健康生活方式。

After adjusting for possible confounding factors,the prevalence rate of IGR and T2DM in patients watching TV time〉 14 h per week was significantly higher than those watching TV time ≤7 h per week（Adjust. OR= 1. 528,95 %CI= 1. 034-2. 121; OR = 1. 482,95% CI= 1. 133 - 2. 047, respectively）. Conclusion Siting and watching TV time were positively correlated with the risk of IGR,T2DM.
