Both aerobic physical activity and muscle-strengthening exercise are recommended for obesity prevention. However, at the population level, the independent and/or combined associations of these physical activity modalities with obesity are unknown. The aim of this study was to examine the associations between aerobic physical activity and muscle-strengthening exercise with obesity among a representative sample of adults.
Data were pooled from four US public health surveillance surveys from 2011 to 2017. Cross-sectional associations between adherence to the aerobic physical activity (≥ 150 min/wk) and muscle-strengthening exercise (≥ 2 times/wk) guidelines with different classes of BMI-defined obesity were examined using Poisson regression. Prevalence ratios are reported as both unadjusted and adjusted for sociodemographic and lifestyle characteristics.
Data were available for 1,677,108 adults (≥ 18 years old). Compared with meeting neither guideline (reference category), meeting both guidelines was associated with the lowest adjusted prevalence ratios (APRs) for the following: Class I obesity and above (BMI ≥ 30.0 kg/m ), APR = 0.54 (95% CI: 0.53-0.54); Class II obesity and above (BMI ≥ 35.0 kg/m ), APR = 0.32 (95% CI: 0.31-0.33); and Class III obesity and above (BMI ≥ 40.0 kg/m ), APR = 0.21 (95% CI: 0.20-0.21).
Among nearly 1.7 million US adults, meeting both aerobic and muscle-strengthening exercise guidelines was associated with a lower obesity prevalence, and associations were more pronounced for higher obesity classes.
有氧运动和肌肉强化运动均被推荐用于预防肥胖。然而，在人群水平上，这些运动方式与肥胖的独立和/或联合关联尚不清楚。本研究旨在检查代表性成人样本中有氧运动和肌肉强化运动与肥胖之间的关联。
数据来自于 2011 年至 2017 年四项美国公共卫生监测调查的数据。使用泊松回归分析了遵守有氧运动（≥150 分钟/周）和肌肉强化运动（≥2 次/周）指南与不同类别 BMI 定义的肥胖之间的横断面关联。未调整和调整社会人口统计学和生活方式特征后的患病率比均有报道。
共有 1677108 名成年人（≥18 岁）的数据可用。与不符合任何指南（参考类别）相比，同时符合两个指南与以下肥胖调整后患病率比（APR）最低相关：I 级及以上肥胖（BMI≥30.0kg/m2），APR=0.54（95%CI：0.53-0.54）；II 级及以上肥胖（BMI≥35.0kg/m2），APR=0.32（95%CI：0.31-0.33）；III 级及以上肥胖（BMI≥40.0kg/m2），APR=0.21（95%CI：0.20-0.21）。
在近 170 万美国成年人中，同时满足有氧运动和肌肉强化运动指南与较低的肥胖患病率相关，且与更高的肥胖级别关联更为显著。
