Cardiometabolic outcomes in offspring of women treated with metformin versus insulin for gestational diabetes: A Systematic Review and meta-analysis
Abstract
INTRODUCTION
Gestational diabetes mellitus (GDM) is commonly managed with either metformin or insulin, but their comparative effects on offspring cardiometabolic outcomes are not fully understood.
OBJECTIVE
To investigate the impact of metformin and insulin, two distinct pharmacological interventions, on cardiometabolic outcomes in offspring of mothers with GDM.
METHODOLOGY
Systematic literature review was performed for articles (randomized control trials) published from 1974 to May 2024 using a predefined search strategy. Studies were screened for title and abstract followed by full text. Quality assessment was done using a separate risk of bias tool in line with the PRISMA-2020 checklist.
RESULTS
Among 5463 records, five studies (metformin = 409 children or insulin n = 434 children) were included. Offspring of metformin-treated mothers in the age range of 5-9 years had more fat-free mass (kg) by bioimpedance and abdominal (subcutaneous and visceral) fat volume (cm3) by MRI. Fasting plasma glucose and triglycerides were lower in the metformin-treated group for offspring aged 5-9 years. No significant differences were observed for other cardiometabolic outcomes. Limited data available for offsprings less than 5 years of age precluded meta-analysis for the available outcomes, except for body weight, and difference for this was also not significant.
CONCLUSION
In short term no major differences has been seen in most of the cardiometabolic outcomes evaluated in the…
