• Aims The aim of this study was to examine the influence of immigration status and region of origin on the risk of type 2 diabetes in women with prior gestational diabetes (GDM). Methods This retrospective population‐based cohort study included women with gestational diabetes (GDM) aged 16 to 50 years in Ontario, Canada, who gave birth between 2006 and 2014. We compared the incidence of type 2 diabetes after delivery between long‐term residents and immigrants—overall, by time since immigration and by region of—using Cox regression adjusted for age, year, neighbourhood income, rurality, infant birth weight and presence of hypertensive disorders of pregnancy (HDP). Results Among 38,515 women with prior GDM (42% immigrants), immigrants had a significantly higher risk of type 2 diabetes compared with long‐term residents (adjusted hazard ratio [HR] 1.19, 95% confidence interval [CI] 1.13–1.26), with no meaningful difference based on time since immigration. The highest adjusted relative risks of type 2 diabetes compared with long‐term residents were found for immigrants from Sub‐Saharan Africa (HR 1.63, 95% CI 1.40–1.90), Latin America/Caribbean (HR 1.44, 95% CI 1.28–1.62) and South Asia (HR 1.34, 95% CI 1.25–1.44). Conclusions Immigration is associated with a significantly higher risk of type 2 diabetes after GDM, particularly for women from certain low‐ and middle‐income countries. Diabetes prevention strategies will need to consider the unique needs of immigrants from these regions.
