The impact of obesity on pregnancy outcomes in women with type 1 and type 2 diabetes across the NSW population: A retrospective cohort study.

Aims

To examine differences in pregnancy outcomes between women with type 1 (T1D) and type 2 diabetes (T2D) and assess the impact of concurrent obesity on adverse perinatal outcomes.

Materials and methods

We retrospectively analysed singleton births of nulliparous mothers with T1D and T2D from 2016 to 2020, in New South Wales, Australia. The incidence of perinatal outcomes was compared between diabetes types. Logistic regression explored the impact of BMI and diabetes type on these outcomes, adjusting for relevant maternal characteristics.

Results
