Mode of birth and social inequalities in health: the effect of maternal education and access to hospital care on cesarean delivery.

Access to health care is an important factor in explaining health inequalities. This study focuses on the issue of access to health care as a driving force behind the social discrepancies in cesarean delivery using data from 707 newborn children in the 2006-2011 birth cohorts of the German Socio-Economic Panel Study (SOEP). Data on individual birth outcomes are linked to hospital data using extracts of the quality assessment reports of nearly all German hospitals. Geographic Information Systems (GIS) are used to assess hospital service clusters within a 20-km radius buffer around mother׳s homes. Logistic regression models adjusting for maternal characteristics indicate that the likelihood to deliver by a cesarean section increases for the least educated women when they face constraints with regard to access to hospital care. No differences between the education groups are observed when access to obstetric care is high, thus a high access to hospital care seems to balance out health inequalities that are related to differences in education. The results emphasize the importance of focusing on unequal access to hospital care in explaining differences in birth outcomes.
