Influence of Physical Activity during Pregnancy on Type and Duration of Delivery, and Epidural Use: Systematic Review and Meta-Analysis.

Cesarean delivery may increase the need for anesthesia administration, thereby causing potential risks to both maternal and fetal health. This article aimed to investigate the effect of physical activity during pregnancy on the type of delivery, the duration of labor, and the use of epidurals (registration No.: CRD42022370646). Furthermore, 57 RCTs ( n = 15301) were included showing that physical activity could decrease the risk of cesarean section (z = 3.22, p = 0.001; RR = 0.87, 95% CI = 0.79, 0.95, I 2 = 37%, P heterogeneity = 0.004), and 32 RCTs ( n = 9468) showed significant decreases in instrumental delivery through performing physical activity (z = 3.48, p < 0.001; RR = 0.84, 95% CI = 0.76, 0.93, I 2 = 0%, P heterogeneity = 0.63). A significant decrease in the 15 RCTs' ( n = 4797) duration of first stage labor was found in physically active pregnant women (z = 2.09, p = 0.04; MD = -62.26, 95% CI = -120.66, -3.85, I 2 = 93%, P heterogeneity < 0.001) compared to those not active. Prenatal physical activity could decrease the risk of cesarean section and instrumental delivery and the duration of first stage labor.
