To determine the magnitude of risk for preterm labor associated with specific clinical and environmental factors.
Using a case-control design, 266 women with preterm labor and 512 controls were interviewed and their medical records reviewed.
Crude and adjusted odds ratios were calculated for each risk factor.
Third-trimester bleeding, twin gestation, and chorioamnionitis at presentation were strongly associated with preterm labor (odds ratios 11.2-48.3).
A history of a prior preterm delivery, vaginal bleeding in the first or second trimester, maternal diethylstilbestrol exposure, uterine anomalies, and urinary tract infection during pregnancy were associated to a lesser extent (odds ratios 1.6-5.4), as were cigarette smoking and drug use (odds ratios 2.0 and 3.0).
