目的：可穿戴活动监测仪是改善2型糖尿病（T2DM）患者代谢结局的有前景的工具，但没有统一的确凿证据.该研究旨在评估使用可穿戴活动监测器进行干预对血糖的影响，血压,血脂，体重,腰围和体重指数（BMI）在T2DM。
方法：两个独立的审阅者搜索了四个在线数据库（PubMed，Cochrane图书馆,WebofScience和Embase）确定2000年1月至2022年10月发表的相关研究。主要转归指标为糖化血红蛋白A1c(HbA1c),次要结果指标包括身体活动（每天步数），空腹血糖,甘油三酯，高密度脂蛋白胆固醇（HDL-C），低密度脂蛋白胆固醇（LDL-C），总胆固醇,收缩压,舒张压,BMI,腰围和体重。
结果：共纳入25项研究。HbA1c[标准化平均差（SMD）=-0.14，95CI（-0.27，-0.02），P=0.02，I2=48%]，BMI[SMD=-0.16，95CI（-0.26，-0.05），P=0.002,I2=0],腰围[SMD=-0.21，95CI(-0.34，-0.09)，P＜0.001，I2=0]，步数/天[SMD=0.55，95CI（0.36，0.94），P<0.001，I2=77%]，有了显著的改善。
结论：基于可穿戴活动监测的干预措施可以促进HbA1c的改善，BMI,2型糖尿病患者腰围和体力活动的增加。可穿戴技术似乎是T2DM自我管理的有效工具，但是没有足够的证据证明它的长期效果。
OBJECTIVE: Wearable activity monitors are promising tools for improving metabolic outcomes in patients with type 2 diabetes mellitus (T2DM); however, no uniform conclusive evidence is available. This study aimed to evaluate the effects of the intervention using wearable activity monitors on blood glucose, blood pressure, blood lipid, weight, waist circumference, and body mass index (BMI) in individuals with T2DM.
METHODS: Two independent reviewers searched 4 online databases (PubMed, Cochrane Library, Web of Science, and Embase) to identify relevant studies published from January 2000 to October 2022. The primary outcome indicator was hemoglobin A1c (HbA1c), and the secondary outcome indicators included physical activity (steps per day), fasting blood glucose, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol, systolic blood pressure, diastolic blood pressure, BMI, waist circumference, and weight.
RESULTS: A total of 25 studies were included. The HbA1c level (standardized mean difference [SMD], -0.14; 95% confidence interval [CI], -0.27 to -0.02; P = .02; I2 = 48%), BMI (SMD, -0.16; 95% CI, -0.26 to -0.05; P = .002; I2 = 0), waist circumference (SMD, -0.21; 95% CI, -0.34 to -0.09; P < .001; I2 = 0), and steps/day (SMD, 0.55; 95% CI, 0.36-0.94; P < .001; I2 = 77%) significantly improved.
CONCLUSIONS: Wearable activity monitor-based interventions could facilitate the improvement of the HbA1c level, BMI, and waist circumference and increase in physical activity in individuals with T2DM. Wearable technology appeared to be an effective tool for the self-management of T2DM; however, there is insufficient evidence about its long-term effect.
