Abstract | BACKGROUND:
Metformin is widely used for the treatment of gestational diabetes. Although some meta-analyses are conducted on the efficacy and safety of metformin, none of them are focused on the Chinese population. The efficacy and safety of metformin in the Chinese GDM population are unknown. AIM: The study aimed to compare metformin to insulin regarding the safety and efficacy in Chinese GDM patients using randomized controlled trials (RCTs) conducted in China. METHOD: Chinese databases (Wanfang, CNKI, VIP, and CBM), PubMed, Embase, Cochrane library, and Scopus were searched for RCTs. The last search date was October 18, 2021. RESULTS: Fifty RCTs (4663 patients) were included in this study after screening. Six outcomes were analyzed. In the main analysis, metformin had lower risk of respiratory distress syndrome (RDS, OR, 0.28; 95% CI 0.16-0.51; P < 0.0001), premature birth (OR, 0.42; 95% CI 0.21-0.85, P = 0.02), and neonatal hypoglycemia (OR, 0.34; 95% CI 0.24-0.48; P < 0.00001) compared to insulin. Moreover, the metformin group is better than the insulin group concerning all other outcomes such as maternal glycemic control and glycated hemoglobin. Subgroup analysis confirmed that metformin has better outcomes than all types of insulin except for RDS, premature birth, 2 h postprandial blood glucose, and glycated hemoglobin. CONCLUSION:
Metformin is considered to be a safe and effective alternative to insulin for the management of GDM if patients refuse insulin due to any reasons in China.
