To investigate the cost-effectiveness of protein-rich meals and snacks for increasing protein intake in home-dwelling older adults.
Cost effectiveness analysis from a randomized controlled trial, the Power Meals study.
Participants were randomized into one of three groups for eight weeks: a protein-rich meal, snack and bread (Protein), a regular meal (Normal) and a control group without meal service (Control).
Home-dwelling home care clients, caregivers and care recipients aged ≥65 years (n = 65).
Protein intake was assessed by a three-day food diary at the end of the study. Cost for the daily diet was estimated by using Finnish grocery store databases and the prices of the food service. The cost-effectiveness was assessed by an incremental cost-effectiveness ratio (ICER).
Costs for the daily diet in the Protein (8.35 €/d) and the Normal (7.94 €/d) groups were significantly higher than in the control group (5.65 €/d) (p < 0.001). Incremental cost-effectiveness analysis showed that increasing protein intake was cost-effective in the Protein group as incremental cost-effectiveness ratio was 8.11 in the Protein, 8.72 in the Normal and 6.45 in the Control group.
Including protein rich meals and snacks in a diet increases protein intake in home-dwelling older adults cost-effectively.
研究富含蛋白质的餐食和小吃对增加居家老年人蛋白质摄入量的成本效益。
随机对照试验（Power Meals 研究）的成本效益分析。
参与者在八周内随机分为三组：富含蛋白质的餐、小吃和面包（蛋白质组）、普通餐（正常组）和无餐服务的对照组（对照组）。
年龄≥65 岁的居家家庭护理客户、护理人员和护理接受者（n=65）。
研究结束时通过三天的食物日记评估蛋白质摄入量。通过使用芬兰杂货店数据库和食品服务价格来估算日常饮食的成本。通过增量成本效益比（ICER）评估成本效益。
蛋白质组（8.35 欧元/天）和正常组（7.94 欧元/天）的日常饮食成本明显高于对照组（5.65 欧元/天）（p<0.001）。增量成本效益分析表明，在蛋白质组中，增加蛋白质摄入量具有成本效益，因为蛋白质组的增量成本效益比为 8.11，正常组为 8.72，对照组为 6.45。
在饮食中添加富含蛋白质的餐食和小吃可以有效地增加居家老年人的蛋白质摄入量。
