Abstract
Objective The purpose of this study was to examine whether women who were treated with 17 alpha-hydroxyprogesterone caproate (17-OHPC) to prevent recurrent preterm birth experienced a change in cervical shortening over time, compared with women who were not treated. Study Design We conducted a retrospective exposure cohort study of women who were enrolled in a prematurity prevention clinic from 1999-2008 with a singleton pregnancy with ≥1 previous spontaneous preterm births (P = .01) than those who were not treated with 17-OHPC. There was no difference in the average weekly change in cervical length among women treated with 17-OHPC, compared with those who were not, after adjustment for covariates (0.79 mm/week; 95% confidence interval, –1.18 to 2.76). Conclusion There was no difference in the average weekly change in cervical length measurements over time in women who underwent 17-OHPC treatment, compared with those who were not treated.Keywords
