This trial examined the effectiveness of an 8-week home meal service on protein and other nutrient intake, physical performance (PP) and health related quality of life (HRQoL) among older people living at home (≥65 years; home care clients, caregivers and care recipients). Participants were randomized into three groups; (1) protein-rich meal, snack, and bread (INT1), (2) regular meal (INT2) and (3) control group. Nutrient intake was assessed with 3-day food diaries, PP with Short Physical Performance Battery (SBBP) and HRQoL with 15 dimensional Health-related quality of life instrument. Total of 67 (59.7% women, mean age 78.2 years) participants ( = 22 INT1, = 24 INT2, = 21 CG) completed the trial. At baseline, mean protein intake was 0.92 (SD 0.32) g/kg adjusted body weight (aBW)/d. At 8 weeks, protein-rich home meal service in INT1 increased protein intake (+ 0.11 (95%CI -0.01 to 0.21) g/kg aBW/d, 9.4 (95%CI 1.0 to 17.8) g/d) compared to other groups. It also increased calcium intake (+169.9 (95%CI 26 to 314) mg/d) and improved results in Sit-to-Stand Test (-4.8 (95%CI -6.8 to -2.7) sec) in INT1 compared to CG. Both home meal services increased saturated fat intake (INT1; 4.6 (95%CI 1.0-8.2) g/d, INT2;7.8 (95%CI 1.9 to 13.7)g/d) and decreased salt intake (INT1;-2330.9 (95%CI -2998 to -1664) mg/d, INT2; -2371.9 (95%CI -3399 to -1345) mg/d) compared to CG. There was no effect on overall HRQoL.
这项试验旨在研究为期 8 周的家庭送餐服务对居家老年人（≥65 岁；家庭护理客户、护理人员和被护理者）的蛋白质和其他营养素摄入、身体机能（PP）以及健康相关生活质量（HRQoL）的影响。参与者被随机分为三组：（1）富含蛋白质的餐食、零食和面包（INT1），（2）普通餐食（INT2）和（3）对照组。通过 3 天的食物日记评估营养素摄入，使用简短身体表现电池（SBBP）评估 PP，使用 15 维度健康相关生活质量工具评估 HRQoL。共有 67 名（59.7%为女性，平均年龄 78.2 岁）参与者完成了试验（INT1 组=22 人，INT2 组=24 人，CG 组=21 人）。在基线时，平均蛋白质摄入量为 0.92（SD 0.32）g/kg 调整后的体重（aBW）/d。在 8 周时，INT1 组的高蛋白家庭送餐服务使蛋白质摄入量增加（+0.11（95%CI-0.01 至 0.21）g/kg aBW/d，9.4（95%CI 1.0 至 17.8）g/d），与其他组相比。与 CG 组相比，INT1 组还增加了钙摄入量（+169.9（95%CI 26 至 314）mg/d），并改善了坐站测试的结果（-4.8（95%CI-6.8 至-2.7）sec）。INT1 和 INT2 组的家庭送餐服务都增加了饱和脂肪的摄入量（INT1：4.6（95%CI 1.0-8.2）g/d，INT2：7.8（95%CI 1.9 至 13.7）g/d），并减少了盐的摄入量（INT1：-2330.9（95%CI-2998 至-1664）mg/d，INT2：-2371.9（95%CI-3399 至-1345）mg/d），与 CG 组相比。对整体 HRQoL 没有影响。
