Risk for neural tube defect-affected pregnancies among women of Mexican descent and White women in California.
This study investigated a previously reported 50% or more increased risk for neural tube defect-affected pregnancies among Latina women compared with White women.
Data were derived from a population-based case-control study of fetuses and live-born infants with neural tube defects in a 1989-through-1991 California birth cohort.
Interviews were conducted with mothers of 538 (88% of eligible) infants/fetuses with neural tube defects and mothers of 539 (88%) nonmalformed control infants.
The risk for a neural tube defect-affected pregnancy was approximately twice as high among women of Mexican descent than among White women (odds ratio=1.9,95% confidence interval [CI]=1.5,2.8).
The odds ratio for Mexico-born Mexican women compared with White women was 2.4 (95% CI=1.7,3.2), whereas the risk for US-born women of Mexican and other racial/ethnic descent was not substantially higher than that for Whites.
The higher risk among Mexico-born Mexican women was not attributable to differences in numerous studied parental characteristics and exposures.
Given that nearly 20% of all California births are to Mexico-born Mexican women, the increased risks observed are relevant to the population burden of neural tube defects.
