Abstract

Abstract : Background: In recent years, the role of metformin in girls with precocious puberty (PP) has been increasingly frequently studied. The objective of this present study is to assess the effect of metformin on low birth weight girls with precocious puberty (LBW-PP girls). Methods: We search the confirmed studies about circulating metformin and PP from the databases of EMBASE, PubMed, and Web of Science. Data were reported as weighted mean difference (WMD) and associated 95% confidence intervals (CIs). Analysis was performed by Review Manager 5.3 and Stata version 12.0. Results: A total of 205 cases (metformin group n = 102, untreated group n = 103) were included in this study. The meta-analysis of randomized controlled trials (RCTs) suggested that metformin had statistically significant effects on testosterone ( P = .001), androstenedione ( P = .022), bone mineral density (BMD; P = .151), triglycerides ( P ≤ .001), body mass index Z score (BMI Z score; P ≤ .001), dehydroepiandrosterone-sulfate (DHEAS; P = .053), sex hormone-binding globulin (SHBG; P = .049), high-density lipoprotein (HDL) cholesterol ( P ≤ .001), low-density lipoprotein (LDL) cholesterol ( P = .021), fat mass ( P ≤ .001), lean mass ( P = .025), and fasting insulin ( P = .002). Conclusion: This meta-analysis provided evidence of the efficacy of metformin in girls with LBW-PP girls, which proved that metformin could improve metabolism and reduce weight. Metformin had a positive effect on preventing LBW-PP girls from developing into obesity and polycystic ovarian syndrome. In addition, this meta-analysis provided important reference opinions and directions for the treatment of LBW-PP girls.
