Description
Wei Zhang and co-authors pool studies in 2026 on exercise during pregnancy and depression before and after birth. Twenty-three studies from ten countries held nearly one hundred twenty-three thousand people. Dose-response math asked how much activity links to how much protection. Both straight-line and curved fits were tested.
Each added block of weekly activity tied to about a six percent lower risk of depression before birth. The curve bottomed out at a moderate weekly dose and faded at very high doses. Late pregnancy showed the clearest gain, while mid-pregnancy and after-birth links were not firm. The dose curve helps shape safe activity advice in pregnancy.
