Association between 25-hydroxy vitamin D levels, physical activity, muscle strength and fractures in the prospective population-based OPRA Study of Elderly Women

P Gerdhem, KAM Ringsberg, KJ Obrant… - Osteoporosis …, 2005 - Springer
Vitamin D supplements have been used to prevent fractures. The effect may be mediated
through increased bone mass, but also through reduced falling propensity. The aim of this …

Biochemical markers of bone metabolism and prediction of fracture in elderly women

P Gerdhem, KK Ivaska, SL Alatalo… - Journal of bone and …, 2004 - academic.oup.com
We studied the ability of various markers of bone turnover to predict fracture in 1040 randomly
