  • Performed age-standardized rate calculations and regional comparisons.

    • Main Results:

    • Suicide risk increased faster in the 15-24 year-old age group for both males and females.
    • Overall age-standardized suicide rates increased for both genders between 1956 and 1981.
    • Males showed a continuous increase in suicide rates, while females peaked in 1976 before declining.
    • Regional analysis indicated a trend of increasing suicide rates towards western Canada for both sexes, with some exceptions.

    Conclusions:

    • The study highlights significant shifts in Canadian suicide rates over 25 years, particularly among young adults.
    • Gender and regional disparities in suicide risk underscore the need for tailored public health interventions.
    • Further research into the underlying causes of these observed trends is warranted.
