Received 29 February 2008; received in revised form 15 April 2008; accepted 24 June 2008. published online 26 August 2008.
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.
