In partnership with Osteoporosis Canada, this project contributes knowledge for use in policy and practice initiatives that improve and promote bone health. The project explores the status and determinants of calcium and vitamin D consumption in Canada, particularly in vulnerable groups. It also addresses the gaps in surveillance by identifying food trends and intake risk factors associated with inadequacy and excess, using both 2004 and 2015 Canadian Community Health Survey (CCHS) - Nutrition data sets. The project will be carried out at the Saskatchewan Research Data Center, Statistics Canada and College of Pharmacy and Nutrition.
