Objective The aim of this study was to determine if cervical dysplasia during pregnancy is associated with pregnancy complications, including preterm delivery and pre-eclampsia.
Study Design A retrospective cohort analyses was performed with propensity-score matching to compare complication rates between pregnant women without history of abnormal cervical cancer screening and pregnant women referred for cervical dysplasia assessment to colposcopy clinic. A composite outcome of pregnancy complications included intra-amniotic infection, preterm premature rupture of membranes, pre-eclampsia, preterm delivery, low birth weight, oligohydramnios, and intrauterine fetal demise. Complication rates were compared between women with and without cervical dysplasia using logistic regression models.
Results Overall cohort included 2,814 women, 279 of whom attended colposcopy clinic for cervical dysplasia assessment. Propensity score–matched cohort included 1,459 women, 274 of whom attended colposcopy clinic. Composite complications of pregnancy rates were not significantly different between control and colposcopy groups in both cohorts (25.3% and 29.0%, P = 0.20; 26.5% and 29.3%, P = 0.45). Dysplasia was not associated with composite pregnancy complications in overall and matched cohorts (odds ratio [OR] = 1.09, 95% confidence interval [CI]: 0.77–1.56) and (OR = 1.03, 95% CI: 0.72–1.49). When cervical dysplasia was determined on biopsy or colposcopy, dysplasia was not associated with complications in the overall and matched cohorts.
Conclusion Biopsy and/or colposcopy determined cervical dysplasia during pregnancy was not associated with pregnancy complications.
