Abstract
Background and aims:
Gestational diabetes mellitus is one of the important complications of pregnancy and is related to many adverse events. There is evidence that probiotics can be considered a preventive and therapeutic option in gestational diabetes mellitus. In this meta-analysis, we have focused on the effect of probiotic yogurt as a natural product on gestational diabetes mellitus.
Methods:
A systematic literature search was done through PUBMED/Medline, Google Scholar, Cochrane Library, and EBSCO up to December 2022. This meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines for the evaluation of the effect of probiotic yogurt on gestational diabetes mellitus.
Results:
Four manuscripts with a total of 533 participants were included in this meta-analysis. There was a statistically significant association between probiotic yogurt and reduced risk of gestational diabetes mellitus (Pooled OR 0.35; 95% CI 0.19-0.62; I2 = 0.0%). Furthermore, the mean reduction in the fasting plasma glucose was significantly higher in the probiotic yogurt groups (Hedges' g = -0.37; 95% CI -0.68 to -0.05; I2 = 0.0%).
Conclusion:
This meta-analysis suggests that probiotic yogurt lowers the risk of gestational diabetes mellitus. Also, it is related to a significant reduction in fasting plasma glucose. These findings promise that probiotic yogurt could be regarded as a safe and low-cost therapy and preventive option for gestational diabetes mellitus. However, more randomized controlled trials with different doses and more probiotic strains with varying systems of delivery are warranted.
