How negative self-perceptions of aging relate to physical activity (PA) in older adults with arthritis is unclear. We examined whether general health mediated the relationship between Awareness of Age-Related change (AARC) losses and PA. We analyzed baseline data from a randomized controlled trial of a PA intervention for adults ≥60 years who self-reported PA, AARC, general health, pain, and social support. We evaluated point-biserial correlations between PA and other factors in participants with self-reported arthritis and developed a mediation model incorporating AARC losses, general health, and PA. We observed significant correlations between PA and general health, social support, and AARC losses in this physically active sample. General health mediated the effect of AARC losses on PA. While negative self-perceptions of aging were associated with less PA in older adults with arthritis, their impact was attenuated by general health. PA interventions for this population may benefit by targeting perceived general health.
在患有关节炎的老年人中，对衰老的负面自我认知与身体活动（PA）之间的关系尚不清楚。我们研究了总体健康状况是否在与年龄相关变化的认知（AARC）丧失和身体活动之间起中介作用。我们分析了一项针对60岁及以上自我报告有身体活动、AARC、总体健康、疼痛和社会支持的成年人进行的身体活动干预随机对照试验的基线数据。我们评估了自我报告患有关节炎的参与者中身体活动与其他因素之间的点二列相关性，并建立了一个包含AARC丧失、总体健康和身体活动的中介模型。在这个身体活跃的样本中，我们观察到身体活动与总体健康、社会支持和AARC丧失之间存在显著相关性。总体健康状况介导了AARC丧失对身体活动的影响。虽然对衰老的负面自我认知与患有关节炎的老年人较少的身体活动有关，但总体健康状况减弱了它们的影响。针对这一人群的身体活动干预可能通过针对感知到的总体健康状况而受益。
