Summary

Socioeconomic deprivation significantly increases the risk of cerebrovascular accidents (CVAs) mortality in Quebec. Even with universal healthcare, disadvantaged populations face higher CVA death rates, highlighting persistent health inequalities.

Area of Science:

  • Public Health
  • Epidemiology
  • Social Determinants of Health

Background:

  • Cerebrovascular accidents (CVAs) are a leading cause of death and disability.
  • Socioeconomic factors are recognized as significant risk factors for CVAs.
  • Understanding these links is crucial for targeted public health interventions.

Purpose of the Study:

  • To investigate the association between material and social deprivation and CVA mortality.
  • To quantify the risk of CVA mortality across different levels of socioeconomic deprivation.
  • To inform public health strategies aimed at reducing CVA-related disparities.

Main Methods:

  • Study population: 4,339 individuals aged 25-74 who died from CVAs between 1994-1998 in Quebec.
  • Socioeconomic status was assessed based on the enumeration area of residence.

  • Poisson regression analysis was employed to estimate relative risks (RR) of mortality.

    • Main Results:

    • A clear mortality gradient was observed for both material and social deprivation.
    • The most disadvantaged group had a relative risk of CVA mortality of 1.34.
    • The most advantaged group had a relative risk of CVA mortality of 1.35, indicating elevated risk even in higher socioeconomic strata.

    Conclusions:

    • Persistent inequalities in CVA mortality exist in Quebec, despite universal healthcare.
    • Socioeconomic deprivation is a significant predictor of CVA mortality.
    • Intervention programs must address social and material deprivation to mitigate CVA disparities.
