We wish to investigate whether a weekly, 2½ hour group-based osteoporosis education intervention (the Osteoporosis Prevention and Self-Management Course), is different to one session course (1x 2½ hours) on osteoporosis knowledge, confidence to eat calcium-containing foods, confidence to exercise, and amount of exercise undertaken after three and nine months of follow-up in people aged over 50 years who have already had a bone fracture.
