Abstract

Objective

The study aimed to explore the short and long-term effects of the Vivifrail-B multicomponent exercise based on society ecosystems theory on physical function in community-dwelling frail older adults.

Methods

59 older adults were randomly assigned to the intervention (n = 30) and control (n = 29) groups. The exercise was performed thrice a week for 12 weeks, with one offline group training and two at home training. The Tilburg Frailty Indicator (TFI), the Short Physical Performance Battery (SPPB), Handgrip strength (HGS), the Physical Self-Maintenance Scale (PSMS), and the Instrumental Activities of Daily Living Scale (IADL) were assessed at baseline, 6 weeks, 12 weeks, 18 weeks, and 24 weeks. Exercise compliance assessments and satisfaction surveys were conducted at post intervention. Generalized estimating equations was used to compare outcome measures.

Results

At T1 (6-week), SPPB (P = 0.040) and PSMS (P = 0.042) of subjects in the intervention group were statistically different from the control group. At T2 (12-week), T3 (18-week) and T4 (24-week), all variables were significantly improved compared to the control group (all, P < 0.05), except for IADL (P_T2 = 0.181, P_T3 = 0.192, P_T4 = 0.163). The short and long-term effects of the intervention were significant compared to the baseline level. However, the differences in Psychology (P = 0.699) and Society (P = 0.644) before and after the intervention were not significant.

Conclusion

Vivifrail-B multicomponent exercise based on society ecosystems theory improved physical function of community-dwelling frail older adults, and the older adults' exercise compliance and satisfaction were high.

基于社会生态系统理论的Vivifrail-B多组分锻炼计划对社区居住体弱老年人身体功能的影响：一项随机对照试验。

目的：探讨基于社会生态系统理论的Vivifrail-B多组分运动对社区居住体弱老年人身体功能的短期和长期影响。方法：59名老年人随机分为干预组（n = 30）和对照组（n = 29）。这项运动每周进行三次，持续12周 ，其中一次是离线小组训练，两次是在家训练。在基线、6 周、12 周、18 周和24 周时评估蒂尔堡虚弱指数（TFI）、短物理性能电池（SPPB）、握力（HGS）、物理自我维持量表（PSMS）和日常生活工具活动量表（IADL）。干预后进行运动依从性评估及满意度调查。使用广义估计方程来比较结果测量。结果：在T1（6周）时，干预组受试者的SPPB （P = 0.040）和PSMS （P = 0.042）与对照组相比有统计学差异。T2（12周）、T3（18周）和T4（24周）时，与对照组相比，各项指标均有显著改善（P均为 T2 = 0.181,PT3 = 0.192,PT4 = 0.163）。与基线水平相比，干预的短期和长期效果显著。干预前后心理（P = 0.699）、社会（P = 0.644）两项差异无统计学意义。结论：基于社会生态系统理论的Vivifrail-B多组分运动改善了社区居住体弱老年人的身体机能，老年人的运动依从性和运动满意度较高。
