A longitudinal assessment of the role of economics on food choices for supporting bone health in older adults using the Canadian Longitudinal Study on Aging

Project Summary

Given the individual and economic burdens associated with osteoporosis and related fractures, prevention strategies are warranted. Diet is a key modifiable risk factor that modulates bone health. Epidemiological investigation of the relationship between diet and bone health does not consider the influence of economic variables, income and food prices. Lower income increases the risk for malnutrition, with consequences to overall health and this includes bone health. The biobehavioural investigation of diet strategies when eating to support bone health is important for determining the practicality of food choices among at-risk individuals, such as those of lower socioeconomic status. This study looks at the association between food costs and bone density and examines the influence of changes in costs and individual financial situations over a period of time. Findings support strategies for an affordable bone promoting diet that recognizes financial barriers that influence food choices.
