A healthy lifestyle and regular physical activity are highly recommended for older adults. However, there has been limited research into testing lifestyle intervention effects on physical activity in older adults with hypertension. The purpose of this study was to assess the association of lifestyle intervention effects with physical activity and blood pressure in older adults with hypertension, accounting for social support and perceived stress as control variables. This study performed a secondary analysis of a two-arm randomized controlled trial. A total of 196 participants were randomly assigned to a six-month lifestyle intervention group or a control group. Hierarchical multiple regression analyses demonstrated that lifestyle intervention effects were not significantly associated with improvements in physical activity and blood pressure, but the final regression models were statistically significant (all < 0.001). The result revealed that only physical activity frequency at baseline was significantly related to improvement in physical activity. Systolic blood pressure (SBP) at baseline and monthly income were significantly associated with change in SBP, while age and diastolic blood pressure (DBP) at baseline were significantly related to change in DBP. The findings provide empirical evidence for developing and optimizing lifestyle interventions for future research and clinical practice in this population.
健康的生活方式和规律的体育活动强烈推荐给老年人。然而，对于患有高血压的老年人，针对生活方式干预对体育活动影响的测试研究非常有限。本研究旨在评估生活方式干预对高血压老年人体育活动和血压的影响，并将社会支持和感知压力作为控制变量。本研究对一项两臂随机对照试验进行了二次分析。共有 196 名参与者被随机分配到为期六个月的生活方式干预组或对照组。分层多元回归分析表明，生活方式干预效果与体育活动和血压的改善没有显著关联，但最终回归模型具有统计学意义（均<0.001）。结果表明，只有基线时的体育活动频率与体育活动的改善显著相关。基线时的收缩压（SBP）和月收入与 SBP 的变化显著相关，而基线时的年龄和舒张压（DBP）与 DBP 的变化显著相关。研究结果为未来在该人群中开展和优化生活方式干预提供了实证依据。
