Influence of aspirin on obstetric outcomes in women with pre-gestational diabetes mellitus: a South-Western Sydney cohort study.

AIM: To investigate the effect of aspirin on obstetric outcomes in women with pre-gestational diabetes mellitus (PGDM).

METHOD: Retrospective audit of pregnant women with PGDM from two centres in South-Western Sydney was conducted. Women were categorised into the aspirin group (prescribed aspirin before 16 weeks, gestation) and non-aspirin group (not prescribed aspirin or prescribed aspirin at or after 16 weeks, gestation). The outcomes examined were pre-eclampsia, pre-term delivery and birthweight percentile.

RESULTS

Of 494 women, 52 (10.5%) were in the aspirin group. Pre-eclampsia developed in 57 (12.0%) women. There was no association between aspirin use and pre-eclampsia (8 (15.4%) vs 49 (11.1%), P = 0.2). Aspirin use was not associated with difference in birthweight percentile and rate of pre-term deliveries when adjusted for maternal age, gravidity and other comorbidities.

CONCLUSION

There was no difference in the rates of pre-eclampsia, pre-term delivery, or birthweight percentile between women with PGDM in aspirin group compared to women in non-aspirin group.
