摘要

为了对抗非西方移民老年人的肌肉减少症，增加身体活动和充足的饮食蛋白质摄入的生活方式干预是有希望的。然而，定期以社区为基础的生活方式干预往往缺乏对文化敏感的方法。本研究的目的是评估新开发的文化敏感生活方式干预对非西苏里南老年人身体表现的影响。设计随机对照试验。参与者本研究纳入了65名非西方移民参与者（苏里南人，65±7岁，91%为女性，82%超重或肥胖）。参与者被分配到文化敏感生活方式干预组（n = 35）和对照组（n = 30）。为期六个月的干预包括运动训练计划和营养计划，两者都适应了参与者的文化和个人需求。主要结果是身体表现，通过6分钟步行测试来衡量。次要指标为站立时间、站立30秒、伸膝强度、单腿站立测试、阑尾瘦软组织量、脂肪量、蛋白质摄入量和每日体力活动。采用线性混合模型评估干预效果，显著性设置为p <； 0.05。结果干预组从基线440±62 m到6个月492±73 m的运动能力提高了12%，对照组从438±93 m到471±66 m的运动能力提高了8% （+25.5 m, 95%CI (3.2;47.9), p = 0.027）。干预组从273±71 N到270±70 N的膝关节伸展强度维持明显较好，而对照组6个月时膝关节伸展强度从262±78 N到240±87 N下降8% （+19 N, 95%CI (1-38), p = 0.040）。与对照组（72±25至78±29 g/天）相比，干预组在三个月时显著增加了蛋白质摄入量（从63±21至78±38 g/天）（+15 g/天，95%CI (1;28), p = 0.035）。两组之间在体力活动或其他次要结果方面没有发现差异。结论：在非西方苏里南移民老年人中，文化敏感的生活方式干预改善了身体机能、蛋白质摄入和保持肌肉力量，为控制该人群肌肉减少症风险提供了一种有希望的方法。试验注册：clinicaltrials .gov （NCT06407583）。

Culture-sensitive lifestyle intervention tailored to non-Western migrant older adults improves physical performance: A randomized controlled trial

Objectives

To counteract sarcopenia in non-Western migrant older adults, lifestyle interventions with increased physical activity and adequate dietary protein intake are promising. However, regular community-based lifestyle interventions often lack a culture-sensitive approach. The aim of this study was to assess the effects of a newly developed culture-sensitive lifestyle intervention on physical performance in non-Western Surinamese older adults.

Design

A randomized controlled trial.

Participants

This study was conducted with 65 non-Western migrant participants (Surinamese, 65 ± 7 y, 91% female, 82% overweight or obese).

Intervention

The participants were allocated to the culture-sensitive lifestyle intervention (n = 35) or control group (n = 30). The six-month intervention consisted of an exercise training program and a nutritional program, both adapted to the cultural and personal needs of the participants.

Measurements

The primary outcome was physical performance, measured by 6-minute walking test. Secondary outcomes were timed-up-and-go, 30-seconds chair stand, knee-extension strength, single leg stand tests, appendicular lean soft tissue mass, fat mass, protein intake and daily physical activity. Linear mixed models were performed to assess intervention effects with significance set at p < 0.05.

Results

The intervention group improved physical performance by 12% from baseline 440 ± 62 m to 6 months 492 ± 73 m compared to 8% in control group from 438 ± 93 m to 471 ± 66 m (+25.5 m, 95%CI (3.2;47.9), p = 0.027). Knee-extension strength was significantly better maintained in the intervention group from 273 ± 71 N to 270 ± 70 N, whereas the control group decreased knee-extension strength by 8% at six months from 262 ± 78 N to 240 ± 87 N (+19 N, 95%CI (1–38), p = 0.040). The intervention group significantly increased protein intake more (from 63 ± 21 to 78 ± 38 g/day) compared to the control group (from 72 ± 25 to 78 ± 29 g/day) at three months (+15 g/day, 95%CI (1;28), p = 0.035). No difference between groups was found for physical activity or the other secondary outcomes.

Conclusions

In non-Western migrant Surinamese older adults, a culture-sensitive lifestyle intervention improved physical performance, protein intake, and maintained muscle strength, presenting a promising approach to manage sarcopenia risk in this population.

期刊介绍： There is increasing scientific and clinical interest in the interactions of nutrition and health as part of the aging process. This interest is due to the important role that nutrition plays throughout the life span. This role affects the growth and development of the body during childhood, affects the risk of acute and chronic diseases, the maintenance of physiological processes and the biological process of aging. A major aim of "The Journal of Nutrition, Health & Aging" is to contribute to the improvement of knowledge regarding the relationships between nutrition and the aging process from birth to old age.
