Abstract

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.

摘要

目的

为应对非西方移民老年人的肌肉减少症，增加身体活动和摄入充足膳食蛋白质的生活方式干预颇具前景。然而，基于社区的常规生活方式干预往往缺乏对文化敏感的方法。本研究旨在评估一种新开发的对文化敏感的生活方式干预对非西方苏里南老年人身体机能的影响。

设计

一项随机对照试验。

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）。

干预措施

参与者被分配到对文化敏感的生活方式干预组（n = 35）或对照组（n = 30）。为期六个月的干预包括一个运动训练计划和一个营养计划，两者均根据参与者的文化和个人需求进行调整。

测量指标

主要结局是身体机能，通过6分钟步行试验测量。次要结局包括计时起立行走测试、30秒椅子站立测试、膝关节伸展力量、单腿站立测试、四肢去脂瘦软组织质量、脂肪量、蛋白质摄入量和日常身体活动。采用线性混合模型评估干预效果，显著性设定为p < 0.05。

结果

干预组的身体机能从基线时的440±62米提高了12%，至6个月时达到492±73米，而对照组从438±93米提高到471±66米，提高了8%（增加25.5米，95%CI(3.2;47.9)，p = 0.027）。干预组的膝关节伸展力量从273±71牛显著更好地维持在270±70牛，而对照组在6个月时膝关节伸展力量下降了8%，从262±78牛降至240±87牛（增加19牛，95%CI(1 - 38)，p = 0.040）。与对照组相比，干预组在三个月时蛋白质摄入量显著增加更多（从63±21克/天增加到78±38克/天），而对照组从72±25克/天增加到78±29克/天（增加15克/天，95%CI(1;28)，p = 0.035）。在身体活动或其他次要结局方面，两组之间未发现差异。
