目的：我们在一个具有代表性的美国成年人样本中研究了体力活动、久坐行为和代谢综合征之间的关系。研究方法和程序：从1999年到2000年参加上午检查的1626名男性和女性，年龄=20岁。代谢综合征的定义采用美国国家胆固醇教育计划的定义。结果：在未调整的分析中，在闲暇时间不从事任何中等或剧烈体育活动的参与者患代谢综合征的几率几乎是那些从事此类活动的人的两倍[优势比(OR)，1.90；95%可信区间(CI)，1.22至2.97]。调整年龄、性别、种族或民族、教育程度、吸烟状况和饮酒可降低OR(OR，1.46；95%CI，0.87至2.45)。与工作外看电视、看录像或使用电脑1h/d的受试者相比，患代谢综合征的调整OR值分别为1.41(95%可信区间0.80~2.51)、1.37(95%可信区间0.85~2.20)、1.70(95%可信区间0.92~3.14)、2.10(95%可信区间1.27~3.47)；=4h/d。额外的体力活动或久坐行为的调整对OR的影响最小。讨论：久坐行为是该综合征患病率的一个重要潜在决定因素。努力减少美国成年人看电视、看视频或使用电脑的时间，特别是如果再加上体力活动的增加，可能会大幅降低代谢综合征的患病率。
Objective: We examined the associations among physical activity, sedentary behavior, and metabolic syndrome in a representative sample of U.S. adults.Research Methods and Procedures: A total of 1626 men and women >= 20 years old from National Health and Nutrition Examination Survey 1999 to 2000 who attended the morning examination were evaluated. The metabolic syndrome was defined by using the definition from the National Cholesterol Education Program.Results: In unadjusted analysis, participants who did not engage in any moderate or vigorous physical activity during leisure time had almost twice the odds of having metabolic syndrome [odds ratio (OR), 1.90; 95% confidence interval (CI), 1.22 to 2.97] as those who reportedly engaged in >= 150 min/wk of such activity. Adjustment for age, sex, race or ethnicity, educational status, smoking status, and alcohol use attenuated the OR (OR, 1.46; 95% CI, 0.87 to 2.45). Compared with participants who watched television or videos or used a computer < 1 h/d outside of work, the adjusted ORs for having metabolic syndrome were 1.41 (95% CI 0.80 to 2.51) for 1 h/d, 1.37 (95% CI 0.85 to 2.20) for 2 h/d, 1.70 (95% CI 0.92 to 3.14) for 3 h/d, and 2.10 (95% CI 1.27 to 3.47) for >= 4 h/d. Additional adjustment for physical activity or sedentary behavior minimally affected the ORs.Discussion: Sedentary behavior is an important potential determinant of the prevalence of the syndrome. Efforts to lessen the amount of time that U.S. adults spend watching television or videos or using a computer, especially if coupled to increases in physical activity, could result in substantial decreases in the prevalence of metabolic syndrome.
