Mattias Lorentzon is a professor and consulting physician in geriatric medicine. He is Program Leader for the Bone Health and Fractures Research Program at the Australian Catholic University (ACU) in Melbourne. He also affiliated with the University of Gothenburg, the Australian Institute of Musculoskeletal Science (AIMSS) and Western Health. Prior to relocating to ACU in Melbourne, he was Chief Physician at the Osteoporosis Clinic and the head of the Sahlgrenska University Hospital Fracture Liaison Service, which investigates over 3000 patients yearly. He has been president of the Swedish Osteoporosis Society (2011-2015), director of the National Osteoporosis Research School, which hosted 55 scientific meetings between 2012- and 2018, and has participated in and led the development of diagnosis and treatment guidelines for the National Board of Health and Welfare (Socialstyrelsen) in Sweden 2009-2014. He has led or participated as investigator in several randomized trials investigating the effect of different interventions on bone density and fracture risk. He has received substantial external funding from several funding agencies, including the National Swedish Research Council (Vetenskapsrådet), since 2005. He is also a member of the FRAX research group (the University of Sheffield), led by professor John Kanis. The use of FRAX has changed clinical practice, been incorporated in most osteoporosis guidelines and is used in 163 countries around the world. The group is now developing FRAXII, an enhanced prediction tool which will incorporate additional risk factors and improve fracture risk prediction substantially. Additional research topics he has focused on include bone microstructure and fracture risk, genetics and bone, probiotic regulation of and bone metabolism. He has published in several high visibility journals including JAMA, the New England Journal of Medicine, the Lancet, Lancet Diabetes and Endocrinology and Nature and made a substantial contribution to the osteoporosis research field, with more than 180 peer-reviewed publications with over 14000 citations.
