title: The effect of 17 alpha-hydroxyprogesterone caproate on pregnancy outcome in an active-duty military population.
abstract: A prior report suggested that active-duty pregnant women are at increased risk for low-birth weight infants and a higher perinatal mortality rate. The present double-blind investigation was designed to prospectively evaluate that risk and to test the efficacy of 17 alpha-hydroxyprogesterone caproate to prevent reported complications. Three groups of active-duty women were studied, beginning between 16 and 20 weeks' gestation. They were similar for parity, previous abortion, race, cigarette smoking, and marital status. Of these, 80 were given 17 alpha-hydroxyprogesterone caproate, 88 received placebo, and 78 declined to participate in the protocol. There was no significant differences in the three groups when comparisons were made for low-birth weight infants and for perinatal mortality. However, when comparison was made to a military dependent population, they had a significantly worse outcome with regard to both perinatal mortality (p = 0.001) and infants with a birth weight less than 2,500 gm (p = 0.01). We concluded that pregnant military personnel were at increased risk for adverse pregnancy outcome, but that this risk was not altered by therapy with 17 alpha-hydroxyprogesterone caproate.
