FINDINGS: Women who lived in regions with high carbon monoxide or fine-particle levels — pollution caused mainly by vehicle traffic — were approximately 10 to 25 percent more likely to have a preterm baby than women who lived in less polluted areas. This was especially true for women who breathed polluted air during the first trimester or during the last months and weeks of pregnancy.
IMPACT: Air pollution in Los Angeles County remains a major public health problem that affects everybody, particularly pregnant women. This study provides further facts to policymakers to weigh the costs and benefits of reducing air pollution, both in terms of dollars and human health.
AUTHORS: Dr. Beate Ritz, professor of epidemiology at the UCLA School of Public Health; Michelle Wilhelm; Katherine J. Hoggatt; and Jo Kay C. Ghosh.
