This study examined the association of total physical activity volume (TPAV) and physical activity (PA) from three domains [leisure-time physical activity (LTPA), domestic, transportation] with metabolic syndrome. We also investigated the relationship between LTPA intensity and metabolic syndrome risk.
Sample included adults who participated in the 1999-2004 National Health and Nutrition Examination Survey. Physical activity measures were created for TPAV, LTPA, domestic PA, and transportational PA. For each, a six-level measure based upon no PA (level 1) and quintiles (levels 2-6) of metabolic equivalents (MET)·min·wk(-1) was created. A three-level variable associated with the current Department of Health and Human Services (DHHS) PA recommendation was also created. SAS and SUDAAN were used for the statistical analysis.
Adults reporting the greatest volume of TPAV and LTPA were found to be 36% [odds ratio (OR) 0.64; 95% confidence interval (CI) 0.49-0.83] and 42% (OR 0.58; 95% CI 0.43-0.77), respectively, less likely to have metabolic syndrome. Domestic and transportational PA provided no specific level of protection from metabolic syndrome. Those reporting a TPAV that met the DHHS PA recommendation were found to be 33% (OR 0.67; 95%; CI 0.55-0.83) less likely to have metabolic syndrome compared to their sedentary counterparts. Adults reporting engaging in only vigorous-intensity LTPA were found to be 37% (OR 0.63; 95 CI 0.42-0.96) to 56% (OR 0.44; 95% CI 0.29-0.67) less likely to have metabolic syndrome.
Volume, intensity, and domain of PA may all play important roles in reducing the prevalence and risk of metabolic syndrome.
本研究考察了总体力活动量（TPAV）和来自三个领域（休闲时间体力活动（LTPA）、家务、交通）的体力活动（PA）与代谢综合征之间的关系。我们还研究了 LTPA 强度与代谢综合征风险之间的关系。
样本包括参加了 1999-2004 年全国健康和营养检查调查的成年人。为 TPAV、LTPA、家务 PA 和交通 PA 制定了体力活动测量。对于每一项，根据无体力活动（水平 1）和代谢当量（MET）·min·wk（-1）五分位数（水平 2-6）创建了一个六级测量值。还创建了一个与当前美国卫生与公众服务部（DHHS）PA 推荐相关的三级变量。SAS 和 SUDAAN 用于统计分析。
报告具有最大 TPAV 和 LTPA 量的成年人患代谢综合征的可能性分别降低 36%（比值比[OR]0.64；95%置信区间[CI]0.49-0.83）和 42%（OR0.58；95%CI0.43-0.77）。家务和交通 PA 并不能提供特定水平的代谢综合征保护。报告符合 DHHS PA 推荐的 TPAV 的成年人患代谢综合征的可能性比久坐不动的成年人低 33%（OR0.67；95%CI0.55-0.83）。报告仅从事剧烈强度 LTPA 的成年人患代谢综合征的可能性降低 37%（OR0.63；95%CI0.42-0.96）至 56%（OR0.44；95%CI0.29-0.67）。
PA 的量、强度和领域都可能在降低代谢综合征的患病率和风险方面发挥重要作用。
