To assess the relationship between self-reported and objectively measured physical activity (PA) and metabolic syndrome and its risk factors in U.S. adults.
A cross-sectional design was used for this study.
The study was set among a nationally representative sample of U.S. adults.
Adults, ages 20 years and older, from the National Health and Nutrition Examination Survey (NHANES) 2003-2006 (n = 5580) participated in the study.
PA measures included minutes per week of moderate plus vigorous PA estimated by self-report (MVPAsr), total 7-day accelerometry (MVPAa), and accelerometer-based MVPA performed in 10-minute bouts (MVPAb). Risk factors for metabolic syndrome included blood pressure, high-density lipoprotein cholesterol, triglycerides, glucose, and waist circumference.
Odds ratios (ORs) for having metabolic syndrome were calculated for men and women who met the Physical Activity Guidelines for Americans compared to those who did not.
Women who did not meet the PA guidelines had significantly greater odds of having metabolic syndrome according to MVPAsr (OR = 2.20; 95% confidence interval [CI] = 1.65-2.94), MVPAa (OR = 4.40; 95% CI = 2.65-7.31), and MVPAb (OR = 2.91; 95% CI = 1.42-5.96). Men had significantly higher odds of having metabolic syndrome according to MVPAa (OR = 2.57; 95% CI = 1.91-3.45) and MVPAb (OR = 2.83; 95% CI = 1.55-5.17), but not MVPAsr. These ORs remained significant after adjusting for all potential confounders except body mass index, after which only MVPAsr in women and MVPAb in men remained significant.
Individuals who do not meet the PA guidelines exhibited greater odds of having metabolic syndrome. This relationship tended to be stronger for objective PA measures than for self-report.
评估美国成年人自我报告的和客观测量的身体活动（PA）与代谢综合征及其危险因素之间的关系。
本研究采用横断面设计。
该研究在美国成年人的全国代表性样本中进行。
来自2003 - 2006年国家健康与营养检查调查（NHANES）的20岁及以上成年人（n = 5580）参与了该研究。
PA测量包括通过自我报告估计的每周中等强度加剧烈强度PA的分钟数（MVPAsr）、7天总加速度计测量值（MVPAa）以及以10分钟时间段进行的基于加速度计的MVPA（MVPAb）。代谢综合征的危险因素包括血压、高密度脂蛋白胆固醇、甘油三酯、血糖和腰围。
计算符合《美国人身体活动指南》的男性和女性与不符合该指南的男性和女性患代谢综合征的比值比（OR）。
根据MVPAsr（OR = 2.20；95%置信区间[CI] = 1.65 - 2.94）、MVPAa（OR = 4.40；95% CI = 2.65 - 7.31）和MVPAb（OR = 2.91；95% CI = 1.42 - 5.96），未达到PA指南的女性患代谢综合征的几率显著更高。根据MVPAa（OR = 2.57；95% CI = 1.91 - 3.45）和MVPAb（OR = 2.83；95% CI = 1.55 - 5.17），男性患代谢综合征的几率显著更高，但根据MVPAsr则不然。在调整除体重指数外的所有潜在混杂因素后，这些OR仍然显著，此后仅女性的MVPAsr和男性的MVPAb仍然显著。
未达到PA指南的个体患代谢综合征的几率更高。这种关系对于客观PA测量往往比自我报告更强。
