Perinatal Outcomes for Asian, Native Hawaiian, and other Pacific Islander Mothers of Single and Multiple Race/Ethnicity: California and Hawaii, 2003-2005.

American Journal of Public Health, 2010

We examined characteristics and birth outcomes of Asian/Pacific Islander (API) mothers to determine whether differences in outcomes existed between mothers of single race/ethnicity and multiple race/ethnicity.Methods.
We used data from California and Hawaii birth certificates from 2003 through 2005 to describe variation in birth outcomes for API subgroups by self-reported maternal race/ethnicity (single versus multiple race or API subgroup), and we also compared these outcomes to those of non-Hispanic White women.Results.
Low birthweight (LBW) and preterm birth (PTB) varied more among API subgroups than between mothers of single versus multiple race/ethnicity.
After adjustment for sociodemographic and behavioral risk factors, API mothers of multiple race/ethnicity had outcomes similar to mothers of single race/ethnicity, with exceptions for multiple race/ethnicity-Chinese (higher PTB), Filipino (lower LBW and PTB), and Thai (higher LBW) subgroups.
Compared with single-race non-Hispanic Whites, adverse outcomes were elevated for most API subgroups: only single-race/ethnicity Korean mothers had lower rates of both LBW (3.4%) and PTB (5.6%); single-race/ethnicity Cambodian, Laotian, and Marshallese mothers had the highest rates of both LBW (8.8%, 9.2%, and 8.4%, respectively) and PTB (14.0%, 13.7%, and 18.8%, respectively).Conclusions.
Strategies to improve birth outcomes for API mothers should consider variations in risk by API subgroup and multiple race/ethnicity.
