Objective: The objective of the study was to investigate the differences in perinatal outcomes between various Asian ethnic subgroups at a national level. Study Design: This is a retrospective cohort study of all non-Hispanic Chinese, Japanese, Filipino, Asian Indian, Korean, Vietnamese, Samoan, Guamanian, and Hawaiian women whose deliveries were recorded by US birth certificates within the year 2003. Perinatal outcomes were compared between groups and potential confounders controlled for with multivariable logistic regression. Results: We found significant differences (P < .001) in the incidence of all perinatal outcomes of interest among the different Asian subgroups. These differences persisted after adjusting for potential confounders. The incidence of diabetes in pregnancy varied from 2.9% (Korean) to 5.7% (Filipina). Conclusion: Our study demonstrates significant differences in preterm labor, primary cesarean delivery, pregnancy-associated hypertension, eclampsia, diabetes in pregnancy, low birthweight, macrosomia, and cephalopelvic disproportion among Asian subgroups at a national level, affirming the importance of examining these subgroups separately.
