MedicalResearch.com: What is the background for this study? What are the main findings?
Response: This study is based on the Global Burden of Disease Study, which is led by the Institute of Health Metrics at the University of Washington. In this study, we present estimates from the Global Burden of Disease Study to describe the major causes of health loss among Canadians, and how these have changed from 1990 to 2016.
In 2016, cancers, cardiovascular diseases, musculoskeletal disorders, and mental and substance use disorders, combined, resulted in over half of the total health loss among Canadians as measured by disability adjusted life years. Disability-adjusted life years is a measure that combines both mortality, through years of life lost, and morbidity, through years lived with disability, into a single measure that allows us to compare health loss from different causes using the same metric.
The all-cause age-standardized years of life lost rate declined 12% between 2006 and 2016, while the all-cause age-standardized years lived with disability rate remained stable (+1%) and the all-cause age-standardized disability-adjusted life year rate declined by 5%.
Finally, between 1990 and 2016, there has been a shift in what contributes to health loss in Canada from premature mortality to disability. In 1990, 45% of total all-cause disability-adjusted life years were due to years lived with disability. By 2016, this proportion grew to 52%. Continue reading
