Physical activity can help improve the poor health-related quality of life in older adult population. Although the Physical Activity Guidelines for Americans recommend both aerobic and muscle strengthening activities for adults, previous studies predominantly focused on aerobic activity with limited research on muscle strengthening activities. The purpose of this cross-sectional study was to examine the relationships between meeting physical activity guidelines (i.e., aerobic activity, muscle strengthening activity) and health-related quality of life in the older adult population. Data of 87,495 older adults aged ≥65 years from the U.S. 2019 Behavioral Risk Factor Surveillance System were analyzed. Phone interviews and validated questionnaires were used to assess aerobic activity, muscle strengthening activity, and health-related quality of life. Binomial logistic regression was used to examine the relationships between meeting physical activity guidelines and health-related quality of life while adjusting for key covariates (i.e., age, sex, race, education, marital status, employment status, income, body mass index, smoking, drinking, and comorbidities). Participants meeting both or aerobic activity guideline only had significantly lower odds of reporting all components of health-related quality of life (i.e., general health, mental health, physical health, activity limitation) than those who met neither guideline (OR = 0.37-0.58) and those who met muscle strengthening activity guideline only (OR = 0.34 - 0.74). Given the stronger positive association between aerobic activity and health-related quality of life than that between muscle strengthening activity and health-related quality of life, future research should focus on promoting aerobic activity to increase health-related quality of life among older people.
身体活动有助于改善老年人群不良的健康相关生活质量。尽管《美国人身体活动指南》建议成年人进行有氧运动和肌肉强化活动，但先前的研究主要集中在有氧运动上，对肌肉强化活动的研究有限。本横断面研究旨在探讨符合身体活动指南（即有氧运动、肌肉强化活动）与老年人群健康相关生活质量之间的关系。分析了来自美国 2019 年行为风险因素监测系统的 87495 名≥65 岁老年人的数据。通过电话访谈和经过验证的问卷评估了有氧运动、肌肉强化活动和健康相关生活质量。使用二项逻辑回归来检验符合身体活动指南与健康相关生活质量之间的关系，同时调整了关键协变量（即年龄、性别、种族、教育程度、婚姻状况、就业状况、收入、体重指数、吸烟、饮酒和合并症）。与既不符合也不符合有氧运动指南的参与者相比，同时符合或仅符合有氧运动指南的参与者报告健康相关生活质量的所有组成部分（即一般健康、心理健康、身体健康、活动受限）的可能性明显降低（OR=0.37-0.58），而仅符合肌肉强化活动指南的参与者的可能性降低（OR=0.34-0.74）。鉴于有氧运动与健康相关生活质量之间的正相关性强于肌肉强化活动与健康相关生活质量之间的正相关性，未来的研究应侧重于促进有氧运动，以提高老年人的健康相关生活质量。
