背景资料：由于人口老龄化的过程和越来越多的前体弱和体弱的个人，新的生活方式干预，以提高生活质量（QoL）在社区居住的老年人是必要的。因此，我们进行了一项随机对照试验（RCT），以比较影响奠定主导的家庭为基础的身体和营养干预计划与社会支持单独对不同的生活质量领域在社区居住的前体弱和体弱的老年adults.Methods：在此分析内的随机对照试验（12周），奠定志愿者访问一对一的前体弱或体弱的老年人在家里每周两次。体能训练和营养干预（PTN）组的参与者进行了六次力量练习，并在每次访问期间讨论了主要的营养问题。社会支持小组每周接受两次家访，进行社会交流。采用WHOQOL-BREF和WHOQOL-OLD量表评估生活质量。协方差分析（ANCOVA）用于检查组间差异，基线值作为协变量。组内的变化进行了评估与配对t-tests.Results：80名参与者（n = 39 PTN组和n = 41 SOSU组）。除PTN组在过去、现在和未来活动领域[β = 3.66（95%置信区间0.13至7.18）]外，两组之间无显著差异。然而，有一些证据表明PTN组的组内改善更大，特别是在总体生活质量、社会关系和社会参与方面。在SOSU组，没有显着的效果，观察到在任何生活质量domain.Conclusion：一个家庭为基础的物理和营养干预相结合的是不是更有效的社会支持相比，单独的生活质量在社区居住前体弱和体弱的老年人。然而，PTN组内的小但显着的改善表明，志愿者提供的以家庭为基础的身体和营养干预可能会影响生活质量的积极方式。
Background: Due to the demographic ageing process and the increasing number of pre-frail and frail individuals, new lifestyle interventions to enhance the quality of life (QoL) in community-dwelling older adults are necessary. Therefore, we performed a randomised controlled trial (RCT) to compare effects of a lay-led home-based physical and nutritional intervention programme with social support alone on different QoL domains in community-dwelling pre-frail and frail older adults.Methods: In this analysis within a RCT (12 weeks), lay volunteers visited one-on-one pre-frail or frail older adults at home twice a week. Participants in the physical training and nutritional intervention (PTN) group performed six strength exercises and discussed main nutritional issues during each visit. The social support (SOSU) group received home visits twice a week for social exchanges. The QoL was assessed with the WHOQOL-BREF and the WHOQOL-OLD instruments. Analyses of covariance (ANCOVA) were used to examine differences between groups with baseline values as the covariate. Changes within groups were assessed with paired t-tests.Results: Eighty participants (n = 39 in the PTN group and n = 41 in the SOSU group) were included. No significant differences were found between the two groups except in past, present and future activities domain [beta = 3.66 (95% confidence interval 0.13 to 7.18)] in favour of the PTN group. However, there was some evidence of greater within group improvements in the PTN group particularly in overall QoL, social relations and social participation. In the SOSU group, no significant effect was observed in any QoL domain.Conclusion: A combination of a home-based physical and nutritional intervention was not more effective compared to social support alone, on QoL in community-dwelling pre-frail and frail older adults. However, the small but significant improvement within the PTN group suggests that a home-based physical and nutritional intervention delivered by volunteers may influence the QoL in a positive way.
