Smoking-Attributable Mortality

HIGHLIGHTS TO TABLE 42/FIGURE 25

  • Smoking-attributable mortality (SAM) is based on estimates of the relative exposure risk of the adult population (age 35 or older). A detailed definition of this term is provided in the Glossary under Smoking-attributable Mortality (SAM). Table 42 presents, for each specific cause of death, the total number of deaths by gender, the proportion of these deaths which are attributed to smoking (labeled SAM%), and the number of SAM deaths. In this annual report, the SAM calculations were updated using data from Tobacco Use In BC, 1998 (available on the internet at http://www.hlth.gov.bc.ca/tobacrs/index.html). This survey identified a drop in smoking prevalence in the province; as a result, the recalculated SAM% values were slightly lower than those used in previous annual reports. Using the revised SAM calculations, there were 5,656 deaths in 1998 that were attributed to smoking.

  • Smoking-attributable mortality can be grouped into deaths from cancers (malignant neoplasms), circulatory system diseases and respiratory system diseases. Out of every 100 smoking-attributable deaths in 1998:

    • 39 were from cancers (malignant neoplasms) (2,210)
    • 37 were from circulatory system diseases (2,104)
    • 24 were from respiratory system diseases (1,342)

  • By specific causes of death, lung cancer (malignant neoplasms of trachea, lung, and bronchus) was the major contributor (1,684 deaths or 29.8% of SAM) to smoking-attributable mortality in 1998, followed by ischaemic heart disease (1,004 or 17.7%) and chronic obstructive pulmonary disease (766 or 13.5%). Together these three causes of death accounted for 3,454 deaths or 61.0% of SAM in 1998.

  • In 1998, three in five smoking-attributable deaths were males (3,449 males or 61.0%, and 2,207 females).
