Physical activity can improve osteoarthritis-related symptoms; however, many people with osteoarthritis (PWOA) are insufficiently active. Social support for physical activity from an intimate partner can help PWOA increase activity, but managing multiple, chronic physical or mental health conditions (i.e., multimorbidity) may influence provision and receipt of that support.
Data from a 1-year longitudinal observational study was used to examine associations between multimorbidity and three dimensions of partner support for physical activity-companionship partner support (doing activity together), enacted partner support, and social support effectiveness-in 169 insufficiently active PWOA and their partners.
Multivariable-adjusted multi-level models indicated baseline differences in support by multimorbidity status: when partners had multimorbidity, PWOA reported receiving less companionship support and less effective support from partners; when PWOA had multimorbidity, partners reported providing less enacted support and both partners and PWOA reported less effective partner support. Broad trends (p < .05) indicate initial increases and subsequent decreases in companionship and enacted partner support when PWOA had multimorbidity, and among partners with and without multimorbidity. When PWOA had multimorbidity, an initial increase in support effectiveness was followed by no significant change; a similar trend was seen among partners with and without multimorbidity.
Multimorbidity may generally contribute to less partner support for physical activity or less effective support, although influences on support over time are less clear. Physical activity interventions for couples experiencing multimorbidity would likely benefit from attention to the impact of multiple chronic health conditions on physical activity and physical activity-related partner support.
身体活动可以改善与骨关节炎相关的症状；然而，许多患有骨关节炎的人（PWOA）活动量不足。来自亲密伴侣的身体活动社会支持可以帮助 PWOA 增加活动量，但管理多种慢性身体或精神健康状况（即，多种共病）可能会影响这种支持的提供和接受。
使用来自一项为期 1 年的纵向观察性研究的数据，研究了 169 名活动量不足的 PWOA 及其伴侣的多种共病状况与身体活动伴侣支持的三个维度（一起活动的同伴支持、实施的伴侣支持和社会支持有效性）之间的关联。
多变量调整的多层次模型表明，支持存在多种共病状况的基线差异：当伴侣患有多种共病时，PWOA 报告收到的同伴支持和来自伴侣的有效支持较少；当 PWOA 患有多种共病时，伴侣报告提供的实施支持较少，并且伴侣和 PWOA 报告的有效伴侣支持较少。初步增加随后减少的趋势（p < 0.05）表明，当 PWOA 患有多种共病时，同伴支持和实施的伴侣支持会增加，而在有和没有多种共病的伴侣中也是如此。当 PWOA 患有多种共病时，支持有效性最初增加，随后没有明显变化；在有和没有多种共病的伴侣中也看到了类似的趋势。
多种共病可能通常会导致伴侣对身体活动的支持减少或支持效果降低，尽管随着时间的推移，对支持的影响不太清楚。对于经历多种共病的夫妇，身体活动干预可能需要注意多种慢性健康状况对身体活动和与身体活动相关的伴侣支持的影响。
