目的

研究玛仕度肽对糖尿病及非糖尿病肥胖人群减重疗效和安全性的Meta分析。

方法

通过检索国内外文献数据库,自建库到2026年1月,纳入包含糖尿病与非糖尿病人群且使用玛仕度肽干预的随机对照试验,采用标准化流程与双研究者盲法质控体系,观察减重疗效相关指标和安全性。

结果

纳入10篇文献,共计2 321例患者。总体上,玛仕度肽较对照组可获得更大的体重下降,且呈现一定的剂量效应梯度。按随访时间分层的合并分析显示,总体趋势上随随访延长减重效应增强。证实玛仕度肽减重获益与随访时长可能相关(MD=-6.57%,95%CI:-8.18%~-4.96%;I2=94%;Z=8.00,P<0.0001)。在安全性结局方面,玛仕度肽可显著增加胃肠道不良反应风险。低血糖方面,两组差异未达统计学显著(RR=1.64,95%CI:0.94~2.84;I2=0%;Z=1.75,P=0.08),Begg’s检验未提示发表偏倚(Z=-0.17,P=0.87),Egger回归截距检验亦未见统计学显著(P=0.27)。

结论

玛仕度肽在糖尿病及非糖尿病肥胖人群中均表现出统计学显著的减重效果,并呈剂量依赖性趋势。鉴于部分分析异质性较高及随访时长有限,疗效幅度与长期获益仍需进一步研究确认。

Objective

To conduct a meta-analysis on the efficacy and safety of mazdutide in weight loss for both diabetic and non-diabetic obese individuals.

Methods

By searching domestic and international literature databases from the establishment of the database to January 2026, randomized controlled trials involving both diabetic and non-diabetic populations and using mazdutide intervention were included. A standardized process and a double-blind quality control system by two researchers were adopted to observe weight loss efficacy-related indicators and safety.

Results

A total of 10 studies were included, involving 2,321 patients. Overall, mazdutide achieved greater weight loss compared to the control group, and a dose-response gradient was observed. Stratified meta-analysis by follow-up time showed that the weight loss effect generally increased with the extension of follow-up. It was confirmed that the weight loss benefit of mazdutide may be related to the follow-up duration (MD=-6.57%, 95%CI: -8.18%~-4.96%; I2=94%; Z=8.00, P<0.0001). In terms of safety outcomes, mazdutide significantly increased the risk of gastrointestinal adverse reactions. Regarding hypoglycemia, no statistically significant difference was found between the two groups (RR=1.64, 95%CI: 0.94~2.84; I2=0%; Z=1.75, P=0.08). Begg's test did not suggest publication bias (Z=-0.17, P=0.87), and Egger's regression intercept test also did not show statistical significance (P=0.27).

Conclusion

Mazdutide demonstrated statistically significant weight loss effects in both diabetic and non-diabetic obese individuals, with a dose-dependent trend. Given the high heterogeneity in some analyses and the limited follow-up duration, the extent of efficacy and long-term benefits still require further research for confirmation.
