The effect of walking during late pregnancy on the outcomes of labor and delivery: A randomized clinical trial.

BACKGROUND

Exercising during pregnancy has various benefits for the mother and the fetus, but there are controversial results about its effect on labor and delivery. Therefore, the present study was conducted to evaluate the effect of walking during late pregnancy on the outcomes of labor and delivery.

MATERIALS AND METHODS

The present randomized clinical trial was conducted on 102 pregnant women who were referred to the comprehensive health service centers of Rafsanjan and were selected using convenient sampling method and randomly were allocated into two groups from August 2018 to February 2019. The intervention group performed walking from the 34 week of pregnancy until the time of delivery 4 times per week, each time for 40 min. The control group just received the routine prenatal care. Information about the outcomes of delivery were gathered from the participants' medical files in the hospital and were analyzed using SPSS software version 22 and Chi-square and independent -tests.

RESULTS

The results indicated that the Bishop score of the intervention group was significantly higher than the control group ( < 0.05). Furthermore, regarding the duration of the third phase of delivery, spontaneous labor, induced labor, cesarean section , and instrumental delivery, a statistically significant difference was observed between the intervention and the control groups ( < 0.05). There was no statistically significant difference between both the groups regarding the duration of the first and the second stages of delivery and Apgar score at 1 and 5 min ( > 0.05).

CONCLUSIONS

Walking during late pregnancy could improve Bishop score, increase spontaneous onset of labor, and decrease induction, cesarean, and instrumental delivery without having any adverse effect on the neonate's Apgar score.
