To understand the global relationship between nutrients, bone health and muscle strength.


  • Review and assess the role of vitamin D, protein, acid base and other nutrients on muscle performance and strength in patients older than 50 years of age. Indeed, alteration of the musculoskeletal system is linked to reduced physical performance, disability, increased risk of fall-related fractures and frailty.
  • The working group envisages conducting a survey on the attitudes and knowledge on nutrition regarding osteoporosis among primary care physicians. This project, under development, would highlight global differences in practice and understanding of nutrition for the prevention of osteoporosis around the world, and identify the challenges still remaining in the education and training of these doctors.


A global review of vitamin D status and determinants of hypovitaminosis D was published in June 2009 in Osteoporosis International. Regional reports were written for North America, Europe, Oceania, Middle-East and Africa, Latin America and finally Asia. The report showed that regardless of whether it is defined at 50nmol/L or 75nmol/L, vitamin D status is seriously inadequate in large proportions of the population across the globe.  See report, and individual regional reports, published in June 2009.
