Abstract

Objective
To determine whether termination of pregnancy (TOP), including the method used or gestational age at termination, affects future obstetric and perinatal outcomes.

Design
Register-based cohort.

Setting
Aberdeen Maternity Hospital, Scotland, UK.

Population
From the Aberdeen Maternity and Neonatal Databank (AMND) we identified 3186 women who had terminated their first pregnancy and then had a second pregnancy of beyond 24 weeks of gestation between 1986 and 2010. We identified 42 446 women who had their first delivery in the same time period, for comparison.

Methods
Univariate and multivariate logistic regression was used to compare outcomes between groups. Complete case analysis with adjustment of confounding factors was carried out, and adjusted odds ratios (aORs) with 99% confidence intervals are presented.

Main outcome measures
The primary outcome was spontaneous preterm delivery (SPTD).
