Birth outcomes among military personnel after exposure to documented open-air burn pits before and during pregnancy.

OBJECTIVE To examine birth outcomes in military women and men with potential exposure to documented open-air burn pits before and during pregnancy. METHODS Electronic data from the Department of Defense Birth and Infant Health Registry and the Defense Manpower Data Center were used to examine the prevalence of birth defects and preterm birth among infants of active-duty women and men who were deployed within a 3-mile radius of a documented open-air burn pit before or during pregnancy. RESULTS In general, burn pit exposure at various times in relation to pregnancy and for differing durations was not consistently associated with an increase in birth defects or preterm birth in infants of active-duty military personnel. CONCLUSIONS These analyses offer reassurance to service members that burn pit exposure is not consistently associated with these select adverse infant health outcomes.
