We conducted 1:1 propensity-score matching to compare SHD users (n\u2009=\u2009211\u00a0451) with non-users. Multivariable logistic regression analyses were conducted, adjusting for osteoporosis, fracture history and comorbidities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Amongst SHD users, 15.28% were prescribed two SHD active pharmaceutical ingredients (APIs) concurrently, and 6.49% received three or more; 15.63% were prescribed two SHD categories, and 4.84% received three or more. The risk of falls or fractures increased with the number of SHDs used. Patients prescribed two SHD APIs had an adjusted odds ratio (aOR) of 1.185 (95% confidence interval [CI]: 1.142\u20131.230) of having a diagnosis of fall or fracture, and those receiving three or more had an aOR of 1.333 (95% CI: 1.266\u20131.404), compared to those on a single API. Similar trends were seen when analysing by drug category.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>SHD polypharmacy is common amongst Korean older population and is associated with a drug count-dependent increase in the risk of falls and fractures.
