Screening for type 2 diabetes after a diagnosis of gestational diabetes by ethnicity: A retrospective cohort study
Abstract
Aims: To estimate rates and identify determinants of post-partum glucose screening attendance in women with a history of gestational diabetes mellitus (GDM).
Methods: Retrospective cohort study using the Clinical Practice Research Datalink linked to Hospital Episode Statistics, to identify women diagnosed with GDM between 01/01/2000 and 05/11/2018. Age adjusted odds ratios (aOR) and 95% confidence intervals (CI) were estimated using multivariable logistic regression models.
Results: In 10,868 women with GDM, with an average follow-up of 5.38 years (95% CI 5.31,5.45), there was an average of 3.79 (95% CI 3.70,3.89) screening episodes per individual, with a mean time to first screening test of 1.22 (95% CI 1.18, 1.25) years. South Asian women had a significantly greater likelihood of being screened compared to White women within the first 5 years post-partum, aOR: 1.89 95% CI (1.20,2.98). A low proportion of women received at least one test per year of follow-up (23.87%). Older age at GDM diagnosis, polycystic ovary syndrome, prescribed medication for GDM, and living in England, were all associated with a greater likelihood of being screened.
Conclusion: While the majority of women with previous GDM receive at least one glucose screening test within the first 5 years post-partum, fewer than a quarter of them receive on average one test per year of follow-up. Developing strategies to motivate more women to attend screening in primary care is essential.
