Sources of Potential Lead Exposure Among Pregnant Women in New Mexico

Abstract  

The objectives of this study were to ascertain the prevalence and potential sources of lead exposure among pregnant women
residing in a socially-disadvantaged immigrant community in Albuquerque, New Mexico. Pregnant women (n = 140) receiving prenatal
care through a community clinic participated in a structured interview and screening to measure their blood lead levels (BLLs).
Potential sources of lead exposure were ascertained by the CDC and New Mexico Department of Health questionnaires. Self-reported
risk factors were examined as predictors of BLLs using multiple linear regression and partial least squares discriminant analysis.
Most patients were Spanish-speaking (88.6%), Latina (95%), foreign-born (87.1%), lacked health insurance (86.4%), and had
a high school education or lower (84.3%). While risk factors were prevalent in this population, only three women (2.1%) had
BLLs ≥3 μg/dL. Results of multivariate analyses demonstrated that pica symptoms in pregnancy, history of elevated BLLs before
pregnancy, use of non-commercial pottery, and living in older houses were important predictors of elevated BLLs. Although
the prevalence of other risk factors relevant to immigrant communities (i.e., use of traditional/folk remedies and cosmetics,
seasonings and food products from Mexico) was high, they were not predictive of elevated BLLs. Clinics providing prenatal
care to immigrant Hispanic communities should carefully assess patients’ pica symptoms, use of non-commercial pottery, and
a history of elevated BLLs. Moreover, additional efforts need to focus on the development of screening questionnaires which
better reflect exposures of concern in this population.
