Investigation on re-pregnancy willingness after two-child policyamong women with scar uterus and analysis of the effects of delivery modes on maternal and infant outcomes

Objective To investigate the willingness of re-pregnancy after two-child policy among women with scar uterus and analyze the effects of delivery modes on maternal and infant outcomes.Methods The willingness of re-pregnancy and related influencing factors of 500 women with single-birth history were investigated. Maternal and infant outcomes were observed in 180 cases of re-pregnant women with scar uterus by different delivery modes.Results There were 244 cases (48. 80%) with re-pregnancy willingness among 500 women. Analysis of influencing factors found that there was a statistically significant difference between first delivery modes and whether they met the two-child policy (P < 0. 05). Logistic regression analysis found that delivery modes and twochild policy were independent risk factors for re-pregnancy willingness (P < 0. 05). The bleeding volume, duration of labor and average length hospital stay in natural labor group were significantly lower than those in cesarean section group (P < 0. 05), and there was no significant difference in neonatal Apgar score and maternal-infant complications between the two groups (P> 0. 05).Conclusions Two-child policy has increased the enthusiasm of women with scar uterus to have second child, and vaginal trial delivery can reduce surgical complications, improve delivery outcomes and safeguard physical and mental health of mother and child.
