Association between interpregnancy interval and pregnancy complications by history of complications: a population-based cohort study.

ABSTRACT:

Objective

To examine if the association between interpregnancy interval (IPI) and pregnancy complications varies by the presence or absence of previous complications.

Design and setting

Population-based longitudinally linked cohort study in Western Australia (WA).

Participants

Mothers who had their first two (n=252 368) and three (n=96 315) consecutive singleton births in WA between 1980 and 2015.

Outcome measures

We estimated absolute risks (AR) of preeclampsia (PE) and gestational diabetes (GDM) for 3-60 months of IPI according to history of each outcome. We modelled IPI using restricted cubic splines and reported adjusted relative risk (RRs) with 95% CI at 3, 6, 12, 24, 36, 48 and 60 months, with 18 months as reference.

Results

Risks of PE and GDM wer
