Associations between Drugs and Fractures
From Ganfyd
Much of the data presented below on associations between fractures and drugs is from case control studies. While many will be familiar twith the association between steroids and fractures, other drugs actually have higher relative risk. The data should be interpreted in the context that much evidence is from a few large patient data bases and so random associations are possible. Even more important, the control for known and unknown independent variables predicting fracture may have been incomplete. The independent variables associated with hip fracture in postmenopausal women without self reported chronic disease include:
- Previous fragility fracture OR=3.33 (CI 1.75-5.66)
- Hip bone mineral density (BMD) OR=3.15 (CI 1.75-5.66)
- Little physical activity OR=2.08 (CI 1.17-3.69)
- Grip strength OR= 2.05 (CI 1.15-3.64)
- Age OR=1.90 (95% CI 1.04-3.46)
- Maternal history of fracture OR=1.77 (CI 1.01-3.09)
- Past falls OR=1.76 (CI 1.00-3.09)
The following variables are probably not independent but have been claimed to be[1]:
- Weight
- Weight loss
- Height loss
- Smoking (see below)
- Neuromuscular coordination
When real patients with chronic disease are studied drugs become more important and both they and certain diseases like depression are strong predictors of fractures.[2]
