Objective To systematically review the preventive effect of breastfeeding intensity and duration on progression to pre-diabetes mellitus (DM) and DM among females with prior gestational diabetes mellitus (GDM).Methods PubMed, Web of Science, CNKI, and WanFang Data databases were electronically searched to collect cohort studies on the correlation of GDM and breastfeeding from inception to January 8th, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 16.0 software.Results A total of 29 cohort studies were included. The results of the meta-analysis showed that breastfeeding could lower the risk of pre-DM (RR=0.64, 95%CI 0.57 to 0.71, P<0.001) and DM (RR=0.75, 95%CI 0.66 to 0.86, P<0.001) among females with prior GDM. Subgroup analysis showed that breastfeeding exhibited protective effects against pre-DM after 0 to 6 months as well as 6 to 12 months. Both breastfeeding for 0 to 6 months and over 12 months could decrease the risk of DM. These effects became prominent with the extension of the follow-up period. However, no significant association was observed between breastfeeding and recurrence of GDM (RR=0.72, 95%CI 0.47 to 1.09, P=0.14).Conclusions Breastfeeding may be a major contributor in protecting against pre-DM and DM among females with prior GDM history. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
