Do Induced Abortions Affect the First Birth Probability? A National Register-Based Study of Danish Women

Abstract

Objective: The focus of this paper is to study, on a national basis, how the event of an induced
abortion modifies the transition to first birth for Danish women aged 20-39 years in the period
1982-2001, taking into account also educational level, family situation, and urbanisation.
Data and methods: The data are obtained by linking several national public registers in Denmark,
using the unique personal identification number. Initially, a logistic regression analysis is employed
in order to model the first birth probability in a given year. Secondly, the long-term effect of an
induced abortion is examined by cumulative first birth probabilities, derived from a life table
analysis.
Main findings and conclusion: Previous abortions increased the first birth probability, though this
effect was almost entirely confined to single women. For cohabiting and married women, previous
abortions had a minimal or no effect on the first birth probability.
