Index of Deprivation:
Deprivation scores for each dissemination area (DA) in Saskatchewan were obtained from the Institut National de Santé Publique du Quebec (INSPQ). The deprivation index includes factors for material and social deprivation derived from the 2006 Canadian Census. The material deprivation factor includes the proportion of people age 15 years and older without a high school diploma, employment/population ratio of people aged 15 years and older, and the average income of people ages 15 years and older in the DA. The social deprivation factor includes the proportion of individuals aged 15 years and older living alone, the proportion of individuals aged 15 years and older who are separated, divorced or widowed, and the proportion of single-parent families. Total deprivation is a combination of material and social deprivation. We calculated RHA and RIC specific deprivation quintiles for total deprivation.
Why chose “Total Deprivation” over “Material” or “Social Deprivation”?
Seven priority health disorders were selected and regression analyses performed to identify the best single predictor of age and sex standardized rates of disease. These conditions included asthma, chronic obstructive pulmonary disease, congestive heart failure, coronary heart disease, injuries, diabetes mellitus and mental disorders. In five (5) of the seven conditions, statistically significant associations were found between total deprivation and disease rates at the level of the province as well as Census Metropolitan Areas/Census Agglomerations. Total deprivation also predicted rates of coronary heart disease in rural areas. In three (3) of the seven disorders, education (proportion of population with no high school certification) predicted disease rates in rural areas while average annual household income was significantly associated with disease rates in two disorders. Given these results, data released to Regional Health Authorities and Regional Intersectorial Committees was stratified by total deprivation.
There are some Dissemination Areas with no deprivation quintile assigned. Dissemination Areas with no population, with a high proportion of collective households or institutionalized persons (more than 15% of the total population or over 80 people living in collective households), with no socio-economic data or no income data, and DAs located on a First Nations reserve cannot be assigned a deprivation score.
