Using the Canadian Longitudinal Study on Aging to undertake a biobehavioural investigation into the association between tooth loss and hip bone mineral density and the role of dietary choices in promoting bone health during later life stages

Osteoporosis is a major public health burden in Canada. As a person ages, bones are more likely to fracture, often leading to a loss of independence and reduced quality of life. A balanced diet can help support bone health. This research adopts a biobehavioral analysis of the relationship between nutrition and bone health by accounting for the roles played by economic factors that affect consumers’ dietary choices. Hip bone mineral density by X-ray scan (used to diagnose osteoporosis) is not routinely performed nor is it well understood by the average person when making health and diet decisions. We use tooth loss as a surrogate measure for bone health since it is observable and meaningful to consumers. Findings will support the development of strategies that enable individuals to consume a healthy diet. In turn, better nutrition will help individuals to keep more of their teeth while supporting overall bone health.
