Proton pump inhibitors therapy and the risk of hip fracture in older people in Taiwan
- 24 Downloads
Conflicting results exist on the relationship between proton pump inhibitors use and hip fracture in old people. The objective of the paper was to explore this issue in Taiwan.
We conducted a population-based case–control study using the database of the Taiwan National Health Insurance Program. Cases included subjects aged 65 years and over with newly diagnosed hip fracture between 2000 and 2013 (n = 7208). Controls included subjects aged 65 years and over without a diagnosis of hip fracture (n = 7208). The cases and the controls were matched with sex, age, comorbidities, and index year of diagnosing hip fracture. The odds ratio and 95% confidence interval for hip fracture associated with proton pump inhibitors use were estimated by the multivariable logistic regression model.
The adjusted odds ratio of hip fracture was 0.96 for subjects with current use of proton pump inhibitors (95% confidence interval 0.76, 1.22), 1.17 for subjects with recent use (95% confidence interval 0.90, 1.52), and 1.12 for subjects with late use (95% confidence interval 0.91, 1.38), compared with never use.
No significant association can be detected between proton pump inhibitors use and the risk of hip fracture in older people in Taiwan.
