Abstract:
Objective:To explore the current situation of maternal childbirth readiness and analyze its influencing factors, providing a basis for improving maternal childbirth readiness.Methods:From March to July 2023, convenience sampling was used to select 355 pregnant women who visited Obstetrics Clinic in three Class Ⅲ Grade A hospitals in Chengde City, Hebei Province as participants. Participants were surveyed using the self-designed General Information Questionnaire, Childbirth Readiness Scale, Perceived Social Support Scale, Family APGAR Index, and Childbirth Self-efficacy Inventory 32. LASSO regression and random forest importance ranking were used to select characteristic variables, and multiple linear regression was combined to enhance interpretability, so as to explore the important factors affecting maternal childbirth readiness.Results:The total score of the Childbirth Readiness Scale for 355 pregnant women was (74.41±7.09), and the mean score of each item was (4.13±0.39). The random forest algorithm showed that when the lambda (λ) value was 0.167 7, the error was minimized, and the corresponding number of influencing factors was six. The top six independent variables in importance ranking were perceived social support, childbirth self-efficacy, gestational week, primiparous status, participation in maternity school, and place of residence. Multiple linear regression analysis showed that perceived social support, childbirth self-efficacy, whether primigravida, gestational week, and participation in maternity school were important influencing factors of maternal childbirth readiness ( P<0.05) . Conclusions:The childbirth readiness of pregnant women is above the middle level. Medical and nursing staff can start with factors that affect the childbirth readiness of pregnant women, adopt personalized nursing measures for pregnant women with different characteristics, and encourage family members to provide sufficient family support to improve the readiness of pregnant women for childbirth.
