Suicide and Age in Alberta, Canada, 1951 to 1977

Cohort Effects of Suicide Mortality Are Sex Specific in the Rapidly Developed Hong Kong Chinese Population, 1976-2010

“…Similar to the present study, different studies using national mortality data in the western countries including USA, England and Wales, Canada, Italy, Australia, New Zealand, Spain, Sweden, and Belgium have reported increased suicide risks in successive male birth cohorts in the post‐war period. Japan, on the other hand, has seen such increased cohort effects in earlier male birth cohorts of the mid‐1920s .…”

Suicide Mortality in Canada and Quebec, 1926-2008: An Age-Period-Cohort Analysis

“…This net cohort effect for males was distinguished beyond the possible effects of underestimation and lack of reliability of the data (variation in time) in the early period of the study; older male cohorts (1846-1916) showed a decreased suicide rate, and no net effect was seen among the parents of the baby-boomers . Previous analyses agree with our findings (Solomon and Hellon 1980;Reed et al 1985: 46;Barnes et al 1986: 208;Newman and Dyck 1988: 679;Mao et al 1990: 324). Additionally, the progressive increase in the cohort suicide effect among men born after World War II has been observed in other countries, notably the USA, West Germany, Switzerland, UK, Spain, and Japan (Murphy and Wetzel 1980;Hafner and Schmidtke 1985;Granizo et al 1996;Riggs et al 1996;Gunnell et al 2003;Ajdacic-Gross et al 2006;Odagiri et al 2011; Keyes and Li 2012); however, our findings and the preponderance of the literature stand in sharp contrast to studies concluding that in Canada cohort is "virtually irrelevant" and "statistically unimportant" in explaining suicide rates (Trovato 1989: 149).…”

An Analysis of the Suicide Rates of Birth Cohorts in Canada

“…They found that the suicide rates of successive cohorts, examined at comparable ages, had increased since 1911. This result agrees well with previous analyses on successive cohorts in Alberta, Canada (Solomon & Hellon, 1980), the United States (Murphy & Wetzel, 1980), West Germany (Hafner & Schmidtke, 1985), and Switzerland (Hafner & Schmidtke, 1985). No such increase in the suicide rates of successive cohorts has been observed in Sweden (Hafner & Schmidtke, 1985).…”
