The Mediterranean Osteoporosis (MEDOS) Study questionnaire.

The Mediterranean osteoporosis study (MEDOS) questionnaire was designed by a group of specialists in bone disease from Southern Europe (MAB Group) and the WHO Collaborating Centre for the Epidemiology of Rheumatic Conditions, assisted by experts from WHO in Geneva and from the European Foundation for Osteoporosis and Bone Disease. The purpose of the questionnaire was to identify putative risk factors for hip fracture in a retrospective case control study applied during a prospective study of the incidence of hip fracture in 14 regions of Europe.
