Nurses work in a unique occupational environment that can require rotating and night shifts, long hours, prolonged standing, heavy lifting, and exposure to chemicals and x-ray radiation. We examined first-trimester exposures among participants of the Nurses’ Health Study II, a prospective cohort established in 1989. In 2001, detailed information on specific exposures during pregnancy was collected from participants for the most recent pregnancy since 1993. Among 6,838 live births, 576 (8%) were born preterm (<37 weeks gestation). Log binomial regression was used to estimate the relative risk (RR) for preterm delivery. The final model included age, parity, work schedule, physical factors, and exposures to chemicals and x-rays.
