Summary

A novel method using last names and country of birth accurately identifies South Asian (SA) and Chinese (CH) ethnicity for mortality studies. This approach revealed significant differences in death rates and patterns among SA, CH, and White (WH) Canadians.

Area of Science:

  • Epidemiology
  • Population Health
  • Biostatistics

Background:

  • Studying ethnic differences in disease is challenging due to lack of ethnicity data.
  • Surrogate measures are often required to infer ethnicity in health datasets.
  • Accurate ethnic classification is crucial for understanding disease patterns.

Purpose of the Study:

  • To develop and validate a novel methodology for identifying South Asian (SA) and Chinese (CH) ethnicity in Canadian mortality data.
  • To compare mortality patterns, including rates of ischemic heart disease, stroke, and cancer, among SA, CH, and White (WH) Canadians.
  • To assess the validity and reliability of using last name and country of birth for ethnic classification.

Main Methods:

  • Developed a method combining last name and country of birth to identify SA and CH individuals in the Canadian Mortality Data Base (CMDB).

Related Experiment Videos

  • Created a name directory of SA and CH names for searching CMDB records.
  • Utilized Census data for population counts and compared ethnicity assignment methods for validity and reliability.

    • Main Results:

    • Identified 10,989 SA and 21,548 CH deaths using the developed method.
    • Found significant birthplace heterogeneity within SA and CH populations.
    • Observed distinct mortality patterns: SA and WH had high ischemic heart disease rates; stroke mortality was similar across groups; CH and WH had high cancer rates, while SA had lower rates.

    Conclusions:

    • Last names and country of birth provide a valid and reliable method for determining SA and CH ethnicity, superior to country of birth alone.
    • The identified contrasting mortality patterns offer hypotheses for further etiological research.
    • This methodology enhances the accuracy of ethnic classification in large-scale mortality studies.
