To evaluate the effectiveness of shared decision-making informed dietary intervention based on digital health technology, for older adults with type 2 diabetes mellitus and determine its impact on patients' glycemic control (hemoglobin A1c (HbA1c) and fasting plasma glucose), physical indicators (blood pressure and body mass index), self-management behavior, and self-efficacy.
A double-arm-randomized controlled trial using a parallel group design was conducted.
124 older adults with type 2 diabetes mellitus recruited from the endocrinology department or diabetes clinics were randomly assigned to the intervention ( = 64) or control group ( = 60).
Patients in the intervention group received shared decision-making informed dietary intervention through the digital health system and those in the controlled group received routine dietary management.
The primary outcome was HbA1c, and the secondary outcomes were fasting plasma glucose, blood pressure, body mass index, self-management ability, and self-efficacy.
After 3 months of intervention, compared to the control group, the intervention group showed a statistically significant decrease in HbA1c, diastolic blood pressure, and fasting plasma glucose ( < 0.05). After the intervention, there were time, group main effects, and interaction effects on diabetes self-management ability and diabetes self-efficacy scores of older adults with type 2 diabetes mellitus ( < 0.05).
The intervention program based on a digital health system significantly improved glycemic control and enhanced self-care ability in older adults with type 2 diabetes mellitus.
Clinicians can integrate digital health technology in behavior change intervention, especially in older adults with chronic disease.
It was registered and approved by the China Clinical Trials Center (ChiCTR2300071455).
评估基于数字健康技术的共同决策知情饮食干预对老年2型糖尿病患者的有效性，并确定其对患者血糖控制（糖化血红蛋白（HbA1c）和空腹血糖）、身体指标（血压和体重指数）、自我管理行为和自我效能的影响。
采用平行组设计进行双臂随机对照试验。
从内分泌科或糖尿病诊所招募的124名老年2型糖尿病患者被随机分配到干预组（n = 64）或对照组（n = 60）。
干预组患者通过数字健康系统接受共同决策知情饮食干预，对照组患者接受常规饮食管理。
主要结局为HbA1c，次要结局为空腹血糖、血压、体重指数、自我管理能力和自我效能。
干预3个月后，与对照组相比，干预组的HbA1c、舒张压和空腹血糖有统计学意义的下降（P < 0.05）。干预后，2型糖尿病老年患者的糖尿病自我管理能力和糖尿病自我效能得分存在时间、组间主效应和交互效应（P < 0.05）。
基于数字健康系统的干预方案显著改善了老年2型糖尿病患者的血糖控制，增强了自我护理能力。
临床医生可以将数字健康技术整合到行为改变干预中，尤其是在患有慢性病的老年人中。
已在中国临床试验中心注册并获得批准（ChiCTR2300071455）。
