Psychiatric admissions and choice of abortion

A statistical analysis is presented of the intensities of admissions to psychiatric hospitals among women in Denmark who either gave birth to a child in the year 1975 or had an induced abortion in the same year. The models used are time‐continuous Markov and semi‐Markov processes, and the methods employed include non‐parametric and semi‐parametric analysis of counting processes. The influence of prior psychiatric admissions on the choice of terminating the pregnancy with an induced abortion is also studied.
