This single-arm observational study explored the feasibility and efficacy of a 12-week personalised physical activity and dietary protein intervention programme for older adults undergoing peritoneal dialysis. Older adults undergoing peritoneal dialysis received eight individualised nutrition and physical activity advice sessions provided by trained nurses. Protein intake and physical activity were regarded as primary outcomes. All data were collected at baseline and at week 12. The enrolment rate was 78.4%. Twenty-nine patients participated in the study. Of these, 86.2% (25/29) completed the intervention. There was a significant increase in protein intake (t = -4.453, P< 0.001) and physical activity levels (Z = -2.929, P = 0.004). Of the participants, 56.0% achieved the targeted protein goal, and 41.4% met the physical activity goal. The timed up-and-go performance (t = 4.135, P = 0.001) increased after intervention. Trained nurses can successfully implement personalised diet and physical activity advice, and achieve promising patient outcomes.

这项单臂观察性研究探讨了针对接受腹膜透析的老年人实施为期 12 周的个性化体育活动和膳食蛋白质干预计划的可行性和有效性。接受腹膜透析的老年人接受了由训练有素的护士提供的八次个性化营养和身体活动建议课程。蛋白质摄入和身体活动被认为是主要结果。所有数据均在基线和第 12 周收集。入组率为 78.4%。29 名患者参与了这项研究。其中，86.2% (25/29) 完成了干预。蛋白质摄入量（ t  = -4.453，P< 0.001）和体力活动水平（Z  = -2.929，P ）显着增加 = 0.004)。在参与者中，56.0% 达到了目标蛋白质目标，41.4% 达到了身体活动目标。干预后，定时启动性能（t  = 4.135，P  = 0.001）增加。训练有素的护士可以成功实施个性化的饮食和身体活动建议，并取得有希望的患者治疗效果。
