Key result
Combined diet and exercise interventions during pregnancy possibly reduced the risk of developing gestational diabetes mellitus compared to standard care (RR 0.85, 95% CI 0.71-1.01).
Why the study?
Gestational diabetes mellitus is increasing in prevalence and carries short- and long-term health risks for women and babies, warranting a summary of Cochrane systematic review evidence on prevention interventions.
Do interventions such as diet, exercise, supplements, or pharmaceuticals prevent gestational diabetes mellitus in pregnant women or women planning a pregnancy?

Relative Risk: 0.85 (95% CI 0.71–1.01)
Combined diet and exercise, myo-inositol, vitamin D, and metformin show possible benefit in preventing gestational diabetes, though further high-quality randomized trials are needed to confirm these findings.

May support combined diet-exercise counseling in pregnancy; leaves open definitive benefit given borderline significance.
Griffith et al. (2020) conducted a systematic review in Gestational diabetes mellitus (n=23,154). Combined diet and exercise interventions vs. Standard care was evaluated on Risk of gestational diabetes mellitus (GDM) (RR 0.85, 95% CI 0.71-1.01). Combined diet and exercise interventions during pregnancy possibly reduced the risk of developing gestational diabetes mellitus compared to standard care (RR 0.85, 95% CI 0.71-1.01).
