Abstract

Opioid use has been reported to be associated with increased fracture risks. In a nested case-control study using the United Kingdom-based General Practice Research Database, we tested the hypotheses that fracture risk was associated with 1) an elevated risk of falls caused by the acute central nervous system effects of opioids including sedation and dizziness, and 2) osteoporosis caused by chronic opioid-induced hypogonadism. Among a cohort of adults aged 18-80 years without cancer who received ≥1 opioid prescription during 1990-2008, we selected cases with a first diagnosed fracture of the hip, humerus, or wrist; up to 4 controls, matched by age, sex, index date (date of the first diagnosed fracture), and general practice, were randomly selected for each case. Adjusted odds ratios and 95% confidence intervals were estimated by using conditional logistic regression. Current use of 1 prescription was associated with a strong risk of fracture (adjusted odds ratio = 2.70, 95% confidence interval: 2.34, 3.13). The risk decreased with increasing use. There was no association with current use of >20 opioid prescriptions. The findings were consistent for all study fractures and for most common opioids, suggesting that acute central nervous system effects of opioids rather than chronic opioid-induced hypogonadism play a key role in fracture risk.
