Physical activity, maternal weight gain, and postpartum weight retention of participants in the OHSU pregnancy, exercise and nutrition study

Moderate-­‐to-­‐vigorous physical activity (MVPA) of ≥ 30 minutes/day at least 4 days/week is recommended during pregnancy to promote appropriate gestational weight gain (GWG). Only about 15% of all women in the United States meet this recommendation during pregnancy. Weight gain during pregnancy and return to pre-­‐ pregnancy weight are important predictors of maternal and fetal health outcomes.
