Research News: New public health research debunks “grey tsunami”

The cross-sectional population-based study included absolute numbers of multimorbidity by age, a finding not usually reported, but of great use to public health policy and primary care strategies. In 2013, more than 73 per cent of Ontarians over the age of 80 had multimorbidity compared to 50 per cent of those aged 65-79, and nearly 20 per cent of those between 45 and 64. However, in absolute numbers, the highest volume of multimorbidity is seen between the ages of 45 and 64, with approximately 754,663.

Of the 17 chronic conditions accounted for in this research, the most prevalent were hypertension, mood disorders, arthritis, diabetes and chronic obstructive pulmonary disease. Increased attention on chronic conditions and multimorbidity can help inform prevention and management strategies, as well as provide insights into how external factors — such as income and geography — influence population health.

The Canadian Journal of Public Health aims to advance public health research and practice in Canada and around the world, contributing to the improvement of the health of populations and the reduction of health inequalities. The independent journal publishes peer-reviewed original research and scholarly articles submitted in either English or French that are relevant to population and public health.
