Gestational diabetes & diabetes in pregnancy
Association between gestational diabetes, ethnicity and migrant length of residence: An Australian cohort study
Main finding · GDMResult — go to the resultAdjusted relative risk 1.37 95% CI 1.31–1.43Authors' conclusion
This study identifies that the most ethnic migrant groups were at a higher risk of GDM than those of the same ethnicity born in Australia and this higher risk of GDM continued over time. Recognising migration effects may improve targeted and meaningful interventions to reduce GDM risk.
Study context
- Population
- Pregnant women at 10 Australian hospitals, June 2020 to November 2023; ethnicity self-identified; South Asian the highest reported ethnic group (18.3%)
- Participants

- Exposure
- Migrants by length of residence vs Australian born
- Length of residence (LOR) <5 yearsn = 9,028
- LOR ≥5 yearsn = 19,282

- Outcome
- GDM risk by ethnicity and length of residence in Australia
