The National Health Interview Survey is unique among US federal surveillance systems with over 20 years of consistent assessment of muscle-strengthening and aerobic activity. The authors examined trends in the prevalence of US adults who met the muscle-strengthening (2 or more days per week) and the combined muscle-strengthening and aerobic physical activity (at least 150 min/wk of moderate-intensity equivalent activity) guidelines from 1998 to 2018.
The 1998-2018 National Health Interview Survey data were analyzed. Age-adjusted prevalence of meeting the muscle-strengthening and combined aerobic and muscle-strengthening guidelines by selected respondent characteristics were estimated for each year and linear and higher-order trends were assessed.
From 1998 to 2018, prevalence of meeting the muscle-strengthening guideline increased from 17.7% to 27.6%, and meeting the combined aerobic and muscle-strengthening guidelines increased from 14.4% to 24.0%. All subgroups demonstrated significant increases in meeting both guideline measures over this period although trends varied across the 21 years; increasing trends were more commonly sustained in the second decade of monitoring.
Although increasing trends in prevalence of meeting the muscle-strengthening and combined guidelines are encouraging, current prevalence estimates remain low. Opportunities exist for the continued promotion of muscle-strengthening activity using evidence-based approaches.
国家健康访谈调查是美国联邦监测系统中独一无二的，它对肌肉强化和有氧运动进行了 20 多年的持续评估。作者研究了 1998 年至 2018 年期间，符合肌肉强化（每周至少 2 天）和结合肌肉强化和有氧体力活动（至少 150 分钟/周的中等强度等效活动）指南的美国成年人的流行率趋势。
对 1998-2018 年国家健康访谈调查数据进行了分析。根据选定的受访者特征，对每年符合肌肉强化和联合有氧和肌肉强化指南的年龄调整流行率进行了估计，并评估了线性和更高阶趋势。
从 1998 年到 2018 年，符合肌肉强化指南的流行率从 17.7%增加到 27.6%，符合联合有氧和肌肉强化指南的流行率从 14.4%增加到 24.0%。在这段时间内，所有亚组都显示出在符合这两个指南方面的显著增加，尽管趋势在 21 年中有所不同；在监测的第二个十年中，增加趋势更为常见。
尽管符合肌肉强化和联合指南的流行率呈上升趋势令人鼓舞，但目前的流行率估计仍然较低。有机会利用循证方法继续促进肌肉强化活动。
