Diabetes screening rates are high in Canada, even for immigrants. However, disparities persist among immigrant subgroups, with multiple doctor visits often needed for recommended screening.
Area of Science:
- Public Health
- Epidemiology
- Health Services Research
Background:
- Diabetes screening is crucial for early detection and management.
- Understanding screening patterns in diverse populations, including immigrants, is essential for health equity.
Purpose of the Study:
- To analyze diabetes screening rates, identify predictors of screening, and estimate the burden of undiagnosed diabetes among immigrants in Ontario, Canada.
- To investigate ethnic variations in diabetes screening and diagnosis within the immigrant population.
Main Methods:
- A population-based retrospective cohort study linked administrative health data with immigration files.
- Followed 3,484,222 diabetes-free individuals aged 40+ in Ontario from 2004-2007 to assess diabetes screening.
- Multivariate regression analysis identified predictors of diabetes testing.
Main Results:
- Immigrant populations had slightly higher overall diabetes screening rates (76.0%) than the general population (74.4%).
- Screening rates varied significantly by country of birth, with highest yields of new diabetes cases in South Asia, Mexico, Latin America, and the Caribbean.
- Immigrant seniors (≥65 years) were screened less than nonimmigrant seniors, and multiple physician visits were often required for high-risk ethnic groups.
Conclusions:
- Canada's universal healthcare system supports high diabetes screening rates, including for high-risk immigrant groups.
- Disparities in screening rates exist among different immigrant subgroups.
- Efforts are needed to ensure equitable access to recommended diabetes screening levels for all immigrant populations.
