Factors Associated with Maternal Healthcare Utilization Before and After Delivery Among Migrant Pregnant Women in China: An Observational Study

Background: Effective healthcare utilization throughout pregnancy is essential in protecting mother and child health, but the maternal healthcare utilization and its associated factors among migrant women are still underexplored. Methods: The data came from the 2018 China Migrants Dynamic Survey. Our analysis included 6337 pregnant migrant women. Prenatal healthcare utilization comprises receiving at least 5 antenatal care (ANC) times and establishing the maternal health record within the first 12 weeks of pregnancy. Postnatal healthcare utilization refers to whether an individual received a postpartum visit and a physical health examination within 28 days and 42 days following delivery. A multivariate binary logit model was employed to investigate the factors related to maternal healthcare utilization. Results: 67.15% of the 6337 participants established health records within the first 12 weeks of pregnancy, and 88.35% received at least five ANC visits. 76.88% and 84.20% of migrant pregnant women received a postpartum visit and a health examination respectively. Age was positively correlated with receiving at least five ANC visits (OR:1.245, 95% CI: 1.038-1.493), a postpartum visit within 28 days (OR: 1.272, 95% CI: 1.107-1.460) and a physical examination within 42 days after delivery (OR=1.174, 95% CI: 1.002-1.376). Education, household income, health insurance and maternal health education were positively associated with prenatal and postnatal healthcare utilization (P
