Proportion of Canadian Adults with Unreported Type 2 Diabetes who Experience a Related Hospitalization: Results from Canadian Community Health Survey and Discharge Abstract Database Linkage

Abstract Background: People with type 2 diabetes (T2D) may go undiagnosed and subsequently be hospitalized with T2D. Objective: Determine the percentage of Canadians, with unreported T2D, who experience a T2D hospitalization Methods: Using linked dataset, respondents who reported no diabetes in the Canadian Community Health Survey, were followed in the Discharge Abstract Database for T2D hospitalization event. Results: 0.56% of men and 0.44% of women, who reported no diabetes, were hospitalized with T2D. Older Age, higher BMI and worse self-reported health increased T2D hospitalization in both men and women. In women, drinking alcohol, smoking tobacco and lower physical activity were associated with an increase in T2D hospitalization. Conclusion: Significant proportion of Canadians experience a T2D hospitalization when self-reporting undiagnosed diabetes. Potential risk factors were identified; however, further research needs to focus on understanding these relationships
