Occupational factors and risk of preterm birth in nurses

Abstract

Objective We evaluated the risk of first-trimester exposures among nurses and the risk of preterm birth among participants of the Nurses’ Health Study II. Study Design Log binomial regression was used to estimate the relative risk (RR) for preterm birth in relation to occupational risk factors, adjusting for age, parity, work schedule, physical factors, and exposures to chemicals and x-rays. Results Part-time work (<= 20 hours a week) was associated with a lower risk for preterm birth [RR=0.7, 95% confidence interval (CI) = 0.6–0.9]. Self-reported exposure to sterilizing agents was associated with an increased risk (RR=1.9, 95% CI = 1.1–3.4). Other exposures, including shift work, physical factors, anesthetic gases, antineoplastic drugs, antiviral drugs, and x-ray radiation were not associated with risk of preterm birth. Conclusions These data suggest that sterilizing agents may be related to preterm birth, while physically demanding work and work schedule are not strong predictors.

Maternal occupation during pregnancy, birth weight, and length of gestation: combined analysis of 13 European birth cohorts

“…These results contradict most of the previous studies where unfavorable effects among nurses were observed, often in relation with specific exposures (15,20,(27)(28)(29); only one study conducted in Canada showed a lower risk of low birth weight infants among nurses (30). Nurses Figure 2.…”

Occupational exposures among nurses and risk of spontaneous abortion

“…32 Our findings regarding exposure to sterilizing agents is consistent with our previously reported association of sterilizing agents with risk of preterm birth (RR=1.9, 95% CI = 1.1-3.4). 33 Glutaraldehyde, formaldehyde, ethylene oxide, orthophthalaldehyde, peracetic acid, and hydrogen peroxide are used to disinfect medical equipment and surgical instruments. Ethylene oxide and formaldehyde are recognized as carcinogenic and mutagenic, but there have been few studies in humans to evaluate their reproductive toxicity, 3,34,35 and most had limited sample sizes.…”
