Traffic-related air toxics and preterm birth: a population-based case-control study in Los Angeles county, California
From the Web page
Numerous studies have associated air pollutant exposures with adverse birth outcomes, but there is still relatively little information to attribute effects to specific emission sources or air toxics. We used three exposure data sources to examine risks of preterm birth in Los Angeles women when exposed to high levels of traffic-related air pollutants – including specific toxics – during pregnancy.
Odds of preterm birth increased 6-21% per inter-quartile range increase in entire pregnancy exposures to organic carbon (OC), elemental carbon (EC), benzene, and diesel, biomass burning and ammonium nitrate PM2.5, and 30% per inter-quartile increase in PAHs; these pollutants were positively correlated and clustered together in a factor analysis. Associations with LUR exposure metrics were weaker (3-4% per inter-quartile range increase).
These latest analyses provide additional evidence of traffic-related air pollution’s impact on preterm birth for women living in Southern California and indicate PAHs as a pollutant of concern that should be a focus of future studies. Other PAH sources besides traffic were also associated with higher odds of preterm birth, as was ammonium nitrate PM2.5, the latter suggesting potential importance of secondary pollutants. Future studies should focus on accurate modeling of both local and regional spatial and temporal distributions, and incorporation of source information.

This blog presents a sampling of health and medical news and resources for all. Selected articles and resources will hopefully be of general interest but will also encourage further reading through posted references and other links. Currently I am focusing on public health, basic and applied research and very broadly on disease and healthy lifestyle topics.
Several times a month I will post items on international and global health issues. My Peace Corps Liberia experience (1980-81) has formed me as a global citizen in many ways and has challenged me to think of health and other topics in a more holistic manner. (For those wishing to see pictures of a 2009 Friends of Liberia service trip to this West African country, please visit www.fol.org. My photo album is included).
This blog is a companion site to my Health and Medical News and Resources Web site with…
- Informational sites and guides
- Links to help from others (as health care providers and support groups)
- Interactive tools (as health calculators and apps)
- Select related news sites and blogs
My professional work experience and education includes over 10 years experience as a medical librarian and a Master’s in Library Science. In my most recent position I enjoyed contributing to our library’s blog, performing in depth literature searches, and collaborating with faculty, staff, students, and the general public.
