Grant: Operating Grant: CCHS - Nutrition Analysis

Calcium and vitamin D are two important nutrients needed for bone health. Yet, using 2004 Canadian Community Health Survey (CCHS) Cycle 2.2 intake data, we have shown that people do not get enough calcium and vitamin D in their diets. The CCHS data set provided a comprehensive picture on food and nutrient intakes of Canadians. Now, release of the CCHS 2015 data set will allow us to investigate other important issues, such as: § The vulnerable groups at-risk of inadequate calcium and vitamin D intake; § The major food sources of calcium and vitamin D and changes since 2004; § To what extent has calcium supplement use dropped off, if at all; § Potential changes in calcium and vitamin D use in those diagnosed with conditions such as osteoporosis, cardiovascular disease, and cancer; § The role of antacids made from calcium carbonate on total calcium intake; § How vitamin D intake from food and supplements has changed since 2004; § The major supplement sources of calcium and vitamin D; § The socioeconomic, geographic, and cultural determinants of supplement use and patterns of use of calcium and vitamin D supplements in people with osteoporosis compared to the general population. This project will contribute knowledge for use in policy and practice initiatives that improve and promote bone health, this in partnership with Osteoporosis Canada. We will explore the status and determinants of calcium and vitamin D consumption in Canada, particularly in vulnerable groups; and address the gaps in surveillance by identifying food trends and intake risk factors associated with inadequacy and excess, using both 2004 and 2015 CCHS Nutrition data sets. By contributing knowledge for use in initiatives that improve and promote bone health, findings will be particularly relevant to health issues, such as osteoporosis, influenced by socio-economic, geographic, and cultural factors and associated with inadequate calcium and vitamin D intake from food and supplements.
