Meta-Analysis
Does exercise reduce the risk of gestational diabetes mellitus, preeclampsia, and spontaneous abortion in healthy pregnant women?
Relative Risk: 0.66 (95% CI 0.5–0.86)
Exercise during pregnancy safely reduces the risk of gestational diabetes mellitus, with any modality and intensity appearing equally effective.
Paulsen et al. (2023) conducted a meta-analysis in Healthy pregnant women. Exercise vs. No exercise was evaluated on Gestational diabetes mellitus (RR 0.66, 95% CI 0.50-0.86). Exercise during pregnancy significantly reduced the risk of gestational diabetes mellitus compared to no exercise (RR 0.66; 95% CI 0.50-0.86), regardless of modality or intensity.
