Figure 1
Age-standardized incidence rates (/100 000) of mesothelioma by year of diagnosis and gender in Alberta, 1980 to 2004
Age-standardized incidence rates increased steadily throughout the study period, reflecting the increases in male pleural mesothelioma. The number of cases in women remained low and constant (APC between 1987 and 2004 was 1.49; 95% CI of -5.40 to 8.89).
Figure 2
Age-specific incidence rates of male pleural mesothelioma in Alberta, 1980 to 2004
In men 60 years and older, the age standardized rates of pleural mesothelioma increased 9.42% (95% CI of 6.91 to 12.00) per year over the study period. Age-specific rates more than doubled in those aged 60 to 69 years, but men 70 years and older showed the highest rate and largest increase between 1980 and 2004.
Figure 3
Age-specific incidence of male pleural mesothelioma by age group and year of diagnosis in Alberta, 1980 to 2004
The incidence of male pleural mesothelioma generally increased with age group at each diagnosis period.
Figure 4
Age-specific incidence for birth cohort 1925 to 1934 based on age-cohort model
The reparametrized age function shows the increase in mesothelioma rate as a cohort is followed over time. For example, in following the 1925 to 1934 cohort over time, we see that the rate per 100 000 increases from 9.1 (when aged 65 to 69 years) to 16.8 (when aged 70 to 74 years). Age-specific rates for other cohorts exhibit similar changes over time, with the highest rates pertaining to the 1930 to 1939 cohort.
Figure 5
Incidence ratios relative to cohort 1925 to 1934 based on age-cohort model
Compared to the 1925 to 1934 cohort, the 1930 to 1939 cohort has 1.13 times the risk of mesothelioma; all other cohorts have lower risk than the 1925 to 1934 cohort. We chose to use the 1925 to 1934 cohort as the reference because it is the middle cohort and therefore more reliably estimated.30 Although the birth cohort years overlap, the people in each cohort differ and therefore the increased risk is not attenuated by the overlap.

Figure 1
Premature mortality rate by quintile of material and social deprivation Canada, 2001
The adjusted premature mortality rate in 2001, 310 deaths per 100 000, progresses in line with both material and social deprivation.
Figure 2a
Premature mortality rate in the most and least deprived persons (material and social) by geographic area and region of Canada, 2001 - MOST DEPRIVED PERSONS
Among the most deprived individuals in Canada, we find that those who live in CAs as well as in small towns and rural communities have the highest rates of premature death.
Figure 2b
Premature mortality rate in the most and least deprived persons (material and social) by geographic area and region of Canada, 2001 - LEAST DEPRIVED PERSONS
Among the most deprived individuals in Canada, we find that those who live in CAs as well as in small towns and rural communities have the highest rates of premature death.
Figure 3a
Ratio and difference in premature mortality between the most and least deprived persons (material and social) by geographic area and region of Canada, 2001 - MORTALITY RATIO
In small towns and rural communities, the relative and absolute discrepancies in the mortality rate (ratio and difference) according to deprivation are relatively low.
Figure 3b
Ratio and difference in premature mortality between the most and least deprived persons (material and social) by geographic area and region of Canada, 2001 - MORTALITY DIFFERENCE
In small towns and rural communities, the relative and absolute discrepancies in the mortality rate (ratio and difference) according to deprivation are relatively low.
