Abstract:
|
Since 1994/95 National Population Health Survey (NPHS) have been collecting longitudinal data on the physical and mental health of Canadians. The objectives were to investigate the long-term effect of addictions on mental health among seniors (55 years and older) who live in rural and urban areas and to examine the effect of risk factors such as alcohol use, smoking and excessive drug use on mental health. From the relatively wide range of mental health indicators available in the NPHS, the mental distress measure was examined as binary outcome (categories: no/low and moderate/high). The analysis was conducted using generalized estimating equation approach accounting for the complexity of multi-stage survey design using bootstrap weights available for incomplete longitudinal data. The missing data issue was also addressed.
