国际体力活动问卷中体力活动强度对中老年人糖尿病患病率的影响

Effect of physical activity strength on the diabetes meilitus prevalence in the elderly under the inflence of International Physical Activity Questionnaire

目的采用国际体力活动问卷（IPAQ）评价广州市中老年人体力活动状况对糖尿病患病率的影响。方法2006年11月至2007年9月从“广州生物库队列研究”第三期招募研究对象中随机选出1996名年龄≥50岁的广州市居民，进行包括详细的生活方式、疾病史等调查，以及身高、体重、腰围、臀围和空腹血糖及葡萄糖耐量等指标的测量和检测。采用IPAQ调查并评价受检者体力活动状况。结果共1932名（96．8％）受试者接受IPAQ体力活动调查，其中体力活动活跃（60．0％）、充分（中等，29．8％）和不足者（10．2％）糖尿病患病率分别为9．1％、12．0％和14．2％。多因素logistic回归分析，在调整了年龄、性别、肥胖等多种潜在混杂因素之后，相对体力活动不足组，体力活动充分和活跃组患糖尿病的OR值分别为0．75（95％CI：0．46～1．26）和0．60（95％CI：0．38～0．97），趋势分析P=0．03。结论经常性的适度体力活动有助于降低中老年人糖尿病患病风险。

Objective To examine the impact of International Physical Activity Questionnaire （IPAQ） physical activity intensity on to the prevalence of diabetes mellitus among Chinese elderly. Methods A total number of 1996 residents aged 50 or above living in Guangzhou city were recruited from the phase 3 of the Guangzhou Biobank Cohort Study. Information on physical activity and fasting plasma glucose status was derived from standardized interviews and laboratory assays. Results Among the participants who were classified as physically active （60.0%）, moderate active （29.8%） and inactive （10.2%）, the prevalence rates of type 2 diabetes mellitus were 9.1%, 12.0% and 14.2%, respectively. After adjustment on age, sex, obesity and other potential confounding factors, data from logistic regression model showed that the odds ratios （95% confidence interval） for diabetes on subjects in physically moderate active and active group were 0.75 （0.46-1.26）and 0.60 （0.38-0.97） respectively with P for trend as 0.03, when comparing to those physically inactive ones. Conclusion Promotion of physical activity might have had some effects in reducing the risk of diabetes mellitus among the older adults.
