Poststroke osteoporosis and consequent fractures increase the risk of morbidity and mortality and cause considerable socioeconomic burden.


To evaluate the association between statin use and risks of osteoporosis and fracture in stroke patients.


Population-based propensity score‒matched cohort study.


Taiwan's National Health Insurance Research Database.


Patients newly diagnosed with a stroke between 2000 and 2012 were identified. After propensity score matching, 5254 patients were included, with 2627 patients in the statin and nonstatin cohorts, respectively.

Main Outcome Measures:

Hazard ratios (HRs) for poststroke osteoporosis, hip fracture, and vertebral fracture (together, the primary outcome) were calculated using Cox proportional hazards regression models according to statin use status.


Poststroke statin use was associated with a lower overall risk of the primary outcome [adjusted hazard ratio (aHR) = 0.66; P < 0.001]. In subanalyses, statin use was associated with a decreased risk of all individual outcomes, including osteoporosis (aHR = 0.68; P < 0.001), hip fracture (aHR = 0.59; P < 0.001), and vertebral fracture (aHR = 0.73; P = 0.003). A dose-effect relationship was identified. The aHRs for developing the primary outcome were 0.96, 0.86, and 0.34 for patients who used 1 to 90, 91 to 365, and >365 cumulative defined daily doses of statins, respectively. These dose-effect relationships were maintained on subgroup analyses stratified by age, sex, and stroke type and sensitivity analyses conducted without propensity score matching.
