Takeaway

  • Women who exercise during pregnancy gain less weight and have fewer related risks.

Why this matters

  • Promotion of a supervised exercise programme during pregnancy may help to control weight gain, reduce maternal and neonatal morbidity, and save on related healthcare costs.

Key results 

  • Women in the intervention group gained less weight (P<.001 had less macrosomia and labor dystocia with women in standard-care group.>
  • Normal vaginal delivery was more common in the intervention group (72.0% vs 56.2%; P=.02) compared with the standard-care group.
  • Cesarean delivery was more likely in the standard-care group (23.9% vs 17.0%; P=.02).
  • Women with pregestational BMI ≥25 kg/min the intervention group were less likely to have excessive weight gain.
