Abstract

Background

Fragile home-dwelling older adults are at risk of undernutrition despite receiving meal delivery services. Weight loss is associated with increased morbidity and mortality. To promote healthy aging, home-delivered between-meal snacks (BMS) were tested in a region of Denmark.

Methods

A quasi-experiment was set up with an intervention group (n=39, mean age 85.3) and a control group (n=32, mean age 80.8). The intervention group received BMS for 18 weeks corresponding to a weekly intake of 5600-9600 kJ and 40-112 g protein. The following outcomes were evaluated: weight, body mass index (BMI), body composition, and handgrip strength.

Results

The intervention group had increased weight (mean ±SD) of 0.88 ±2.96 kg and fat mass of 1.56 ±2.55 kg but reduced muscle mass of 0.14 ±1.09 kg resulting in an increased BMI of 0.35 ±1.22 kg/m². For comparison, the results of the control group were as follows: 0.29 ±2.56 kg, 0.27 ±3.65 kg, -0.04 ±1.76 kg, and 0.12 ±0.44 kg/m². The between-group mean differences were not statistically significant. The intervention group had an increased right handgrip strength of 1.40 ±5.27 kg, while a decrease of 1.41 ±3.27 kg was observed for the control group resulting in a statistically significant between-group mean difference.

Conclusion

This study suggests that BMS may reduce the risk of undernutrition and improve the functional status among fragile home-dwelling older adults, although the effect is minor. Nevertheless, the frequency of unplanned weight loss was lower within the intervention group even though the group constituted a more fragile population.

为脆弱的老年人提供的家庭餐间小吃——一项试点研究

背景:尽管接受送餐服务，脆弱的居家老年人仍面临营养不良的风险。体重减轻与发病率和死亡率增加有关。为了促进健康老龄化，在丹麦的一个地区测试了家庭提供的餐间零食(BMS)。方法设置准实验，干预组(n=39，平均年龄85.3)和对照组(n=32，平均年龄80.8)。干预组接受BMS治疗18周，相当于每周摄入5600-9600千焦和40-112克蛋白质。评估以下结果:体重、身体质量指数(BMI)、身体成分和握力。结果干预组体重增加(平均±SD) 0.88±2.96 kg，脂肪增加(1.56±2.55 kg)，肌肉减少(0.14±1.09 kg)， BMI增加(0.35±1.22 kg/m2)。对照组的结果分别为0.29±2.56 kg、0.27±3.65 kg、-0.04±1.76 kg、0.12±0.44 kg/m2。组间平均差异无统计学意义。干预组右手握力增加1.40±5.27 kg，对照组右手握力减少1.41±3.27 kg，组间平均差异有统计学意义。结论本研究提示BMS可降低脆弱居家老年人的营养不良风险，改善其功能状态，但效果较小。然而，在干预组中，计划外减肥的频率较低，尽管这一组是一个更脆弱的人群。
