Socioeconomic differences in perinatal health and disease.

Introduction: The Danish Medical Birth Register has been used extensively in conjunction with other national registers to examine different aspects of socioeconomic differences in perinatal health outcomes. Here, we review some recent findings.

Research Topics: Socioeconomic differences were observed in stillbirth, preterm birth, birthweight, congenital anomalies, and infant death. The patterns varied according to the health outcome and measure of socioeconomic position, but also according to the time period and the country under study. Our review also shows how many different strategies have been used to examine the influence of socioeconomic factors on perinatal health.

Conclusion: Danish register data is an invaluable source of information on socioeconomic differences in perinatal health. Danish registers continue to provide excellent opportunities for research and surveillance in this area.
