To investigate whether and how social support influenced frailty progression through depressive symptoms and physical activity.
Of 1235 community-dwelling older adults enrolled at baseline, 778 (63.0%) undergoing at least one yearly follow-up were included in the final analysis. Data were collected on frailty, social support, depressive symptoms, physical activity and covariates.
Two frailty trajectory classes were identified and labeled as alleviated frailty and deteriorated frailty. Subjective support prevented the deterioration of frailty through decreased depressive symptoms, while objective support and support utilization prevented the deterioration of frailty through increased physical activity.
The pathways through which social support ameliorates frailty vary by support types. Subjective support interventions should be included in the multifactorial interdisciplinary management of frailty to address social and psychological vulnerabilities, along with objective support and support utilization interventions addressing physical inactivity.
探讨社会支持是否以及如何通过抑郁症状和身体活动影响虚弱进展。
在基线时纳入了 1235 名居住在社区的老年人，其中 778 名（63.0%）至少进行了一次年度随访，最终纳入了本项分析。收集了虚弱、社会支持、抑郁症状、身体活动和协变量的数据。
确定并标记了两种虚弱轨迹类别，分别为缓解虚弱和恶化虚弱。主观支持通过降低抑郁症状来防止虚弱的恶化，而客观支持和支持利用则通过增加身体活动来防止虚弱的恶化。
社会支持改善虚弱的途径因支持类型而异。在多因素跨学科虚弱管理中应包括主观支持干预，以解决社会和心理脆弱性问题，同时还应包括客观支持和支持利用干预，以解决身体不活动问题。
