IOF announces research to support development of Global Map of Dietary Calcium Intake

Data from systematic review will support an interactive map of average dietary calcium intake – an impactful new resource which will help to improve our understanding of current calcium intake status around the world.

Globally, there is concern that low calcium intake is adversely affecting bone health in many populations around the world. To better understand the current status of calcium intake IOF has commissioned a systematic review of the evidence for average calcium intake by country.

The project was announced at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases, where lead investigator Dr Ethan Balk, Associate Professor Brown Evidence-based Practice Center Brown University, US, discussed the research underway. Searching key databases for studies reporting national average dietary calcium intake in adults, the researchers have prioritized larger population surveys conducted since 2000, but included older and smaller studies as necessary. Mean or median dietary calcium intake was extracted for the total sample and for subgroups by age, sex and socioeconomic factors. The review will focus on adults, excluding studies of intake in children, institutionalized adults, those with comorbidities, and pregnant or lactating women.

Once definitive analysis of data has been concluded, and in conjunction with the publication of the systematic review, IOF looks forward to the launch of an interactive, colour-coded, global map. The Global Map of Dietary Calcium Intake will help healthcare professionals and healthcare authorities identify populations at risk of inadequate dietary intake.

The Global Map of Dietary Calcium Intake is supported by an unrestricted educational grant from Pfizer Consumer Health.
