To examine the association and relative contribution of different levels of physical activity (PA) with metabolic syndrome (MS).
The cluster sampling method was used to recruit 8,750 community-based individuals between 40 and 60 years of age. MS was defined according to the International Diabetes Federation, 2005. PA was estimated with the International Physical Activity Questionnaire, and three levels of PA (low, moderate, vigorous) were used to classify the individuals. The risk factors of MS were comprehensively collected, and logistic regression methods were used to measure the association between PA and MS. Population-attributable risks and their 95% confidence intervals (CI) were calculated based on the regression model.
Approximately 30.4% (2,661) of the participants were MS patients. The percentage of individuals with vigorous levels of PA was 46.2% and 43.5% and with low levels of PA was 11.3% and 11.3% in non-MS and MS group, respectively. Individuals with vigorous PA had an odds ratio (OR) of 0.78 (95% CI: 0.66, 0.91) for MS compared with those with low PA, and the OR for individuals with moderate PA was 0.85 (95% CI: 0.73, 1.01). Moderate and vigorous PA levels decreased risk of MS by 18.3%, with approximately 11% of that decrease due to vigorous PA.
Vigorous PA levels were consistently associated with a reduced risk of MS; however, a protective role of moderate PA was not found. The population-attributable risk for vigorous PA was about 11% for all MS risk factors.
探讨不同水平的身体活动（PA）与代谢综合征（MS）之间的关联及相对贡献。
采用整群抽样法招募了8750名40至60岁的社区居民。MS根据2005年国际糖尿病联盟的标准定义。使用国际体力活动问卷评估PA，并将个体分为三个PA水平（低、中、高）。全面收集MS的危险因素，采用逻辑回归方法测量PA与MS之间的关联。根据回归模型计算人群归因风险及其95%置信区间（CI）。
约30.4%（2661名）参与者为MS患者。非MS组和MS组中，高水平PA个体的比例分别为46.2%和43.5%，低水平PA个体的比例均为11.3%。与低水平PA个体相比，高水平PA个体患MS的比值比（OR）为0.78（95%CI：0.66，0.91），中等水平PA个体的OR为0.85（95%CI：0.73，1.01）。中等和高水平PA可使MS风险降低18.3%，其中约11%的降低归因于高水平PA。
高水平PA始终与MS风险降低相关；然而，未发现中等水平PA的保护作用。对于所有MS危险因素，高水平PA的人群归因风险约为11%。
