Type 1 diabetes

The role of sex and ethnicity in the variability of estimated glomerular filtration rate ( estimated glomerular filtration rate (eGFR) ) in people with type 1 diabetes

Diabet MedPublished Cohort study

Authors' conclusion

Interactions between sex and ethnicity may determine the heterogeneity in kidney function decline.

Study context

Population
People with T1D and baseline eGFR ≥45 mL/min/1.73 m²; 48% men (81% White, 12% African-Caribbean, 7% Other)
Participants
1,495 people
Exposure
Sex and ethnicity groups
Outcome
Sex-specific eGFR trajectories and role of sex and ethnicity interaction in predicting eGFR decline
Follow-up
10 years
Methodological detailsgroup-based trajectory modelling, linear mixed models
  • Group-based trajectory modelling

Lowest eGFR sex gap in African-Caribbeans, highest in 'Other'
