Using logistic regression and marginal standardization, we estimated the effects of exposure to black carbon, nitrogen dioxide and ultrafine particles on preterm birth after confounder adjustment and stratification by race/ethnicity.<h4>Results</h4>There were 8823 singleton births, of which 760 (8.6%) were preterm. Shifting black-carbon exposure from the 10th to the 90th percentile was associated with: 6.8%age point higher risk of preterm birth (95% confidence interval = 0.1 to 13.5) among Black women; 2.1%age point higher risk (95% confidence interval = -1.1 to 5.2) among Latinas; and inconclusive null findings among Asian and White women. For Latinas, there was evidence of a positive association between the other pollutants and risk of preterm birth, although effect sizes were attenuated in models that co-adjusted for other TRAP.<h4>Conclusions</h4>Exposure to TRAP, especially black carbon, may increase the risk of preterm birth for Latina and Black women but not for Asian and White women."],"journal":["International journal of epidemiology"],"pubmed_title":["Hyper-localized measures of air pollution and risk of preterm birth in Oakland and San Jose, California."],"pmcid":["PMC8932296"],"funding_grant_id":["UH3 OD023272","UG3OD023272","R00 ES027023","P30 ES009089","UG3 OD023272","UH3OD023272"],"pubmed_authors":["Morello-Frosch R","Casey JA","Torres JM","Riddell CA","Goin DE","Glymour MM","Apte JS"],"additional_accession":[]},"is_claimable":false,"name":"Hyper-localized measures of air pollution and risk of preterm birth in Oakland and San Jose, California.","description":"<h4>Background</h4>US preterm-birth rates are 1.6 times higher for Black mothers than for White mothers.
