The impact of educational interventions on modifiable risk factors for osteoporosis after a fragility fracture.

The purpose of this study was to investigate the impact of two educational interventions on the intake of calcium and vitamin D supplements and modifiable risk factors for osteoporosis in women ≥50 years with a fragility fracture (FF). Within 6-8 months of fracture, women were randomized to one of three intervention groups: usual care (UC), written materials (WM), or videocassette and written materials (VC). The written materials for patients and their physician provided information on osteoporosis, FF, and available treatments; written materials for physician were provided through patients. The videocassette presented similar information as the written material, but in greater depth. Twelve months after randomization, the effectiveness of the interventions was assessed. The study cohort consisted of 1,175 women undiagnosed and untreated for osteoporosis. After 12 months, the mean intake of Ca supplements increased by 33, 93, and 91 mg/day for the UC, WM, and VC groups, respectively (p value, WM vs UC = 0.163; VC vs UC = 0.026); the corresponding mean increases for vitamin D were 58, 105, and 118 IU/day (p value, WM vs UC = 0.214; VC vs UC = 0.012). The proportion of women who increased their Ca and vitamin D intake by supplements was similar in all three groups. The intervention had a greater impact in those not taking supplements at randomization and had no impact on modifiable risk factors. In women without diagnosis and treatment for osteoporosis, the interventions seem effective at increasing the amounts of Ca and vitamin D supplements, but not effective at inciting more women to increase their consumption. Therefore, the clinical significance of the impact of the intervention is difficult to evaluate.
