Risk of preterm birth after treatment for cervical intraepithelial neoplasia among women attending colposcopy in England: retrospective-prospective cohort study.

ABSTRACT:

Objective

To explore the association between preterm delivery and treatment at colposcopy.

Design

Retrospective-prospective cohort study using record linkage.

Setting

12 National Health Service hospitals in England.

Participants

Women who had a cervical histology sample taken between 1987 and 2009. These women were linked by hospital episode statistics to hospital obstetric records between 1998 and 2009 for the whole of England to identify singleton live births between 20-43 gestational weeks before or after cervical histology.

Main outcome measures

Proportion of preterm births (<37 weeks); the relative risk for the strength of association between preterm births and treatment for cervical intraepithelial neoplasia.

Results

18,441 singleton births
