The pregnancy outcomes of the two groups were followed up.Results The cesarean section rate, the average amount of postpartum bleeding and the newborns weights were lower and the delivery time was shorter in the training group than in the control group. The breastfeeding rate in the training group was higher than the control group. There was a statistical difference between the two groups.Conclusion The maternal health care exercise can effectively reduce the incidence of macrosomia, the rate of cesarean section, and promote natural delivery. It is safe and effective. It is worthy of further research and popularization.
