Aerobic Exercise on Prenatal Sleep Quality and Maternal-fetal Attachment

A growing body of evidence suggests that exercise is an important contributor to maternal health and is beneficial to infants. A single-blinded randomised experimental study was used to evaluate the effect of aerobic exercise on sleep quality and maternal-fetal attachment in pregnancy women. 140 eligible pregnant women were systematically assigned, with a random start to experimental group (n = 70) received a 20 minutes aerobic exercise video and was instructed to exercise at least three times a week for 3 months at home, while the control group (n = 70) received the usual care only. The Pittsburgh Sleep Quality Index and Modified Maternal-Fetal Attachment Scale were used to assess outcomes measured before the intervention and at 4 and 12 weeks postintervention. Paired sample t-tests were conducted before and after aerobic exercise to measure whether there were any statistically significant changes in outcome variables.
