The socioeconomic burdens of osteoporosis and related fractures have increased in parallel with population aging. The Korea Society of Bone and Mineral Research published fact sheets on these topics in 2017, 2018, and 2019. This study provides complied epidemiological data based on these fact sheets for understanding current status of osteoporosis in Korea. Data from the Korea National Health and Nutrition Examination Survey (2008–2011) performed by the Korea Centers for Disease Control and Prevention and from National Health Information database (2008–2016) by National Health Insurance Service of Korea was used for analyzing the prevalence and incidence of osteoporosis and related fractures, respectively, fatality rates after fractures, and prescription status of anti-osteoporotic medications (AOMs). Among Korean adults aged ≥50 years, 22.4% and 47.9% had osteopenia or osteoporosis, respectively. Incidences of osteoporotic hip, vertebral, humerus, and distal radius fractures plateaued in 2013. The cumulative incidence of subsequent fractures gradually increased over 4 years of follow-up once an osteoporotic fracture occurred. Crude fatality rates in the first 12 months after hip fracture were 14.0% for women and 21.0% for men. Only 33.5% of patients with osteoporosis took AOMs, and even after an osteoporotic fracture, only 41.9% of patients took AOMs within the following 12 months. Despite a steady increase in AOM prescriptions of ~6% per annum, only 33.2% of patients were medication compliant (medication possession ratio ≥80%) at 12 months after treatment initiation. Continuous efforts are required to diagnose patients at high risk of fracture and ensure proper management in Korea.
