Prevalence Trends of Site‐Specific Osteoarthritis From 1990 to 2019: Findings From the Global Burden of Disease Study 2019

OBJECTIVE: To estimate systematic and anatomic site-specific age-standardized prevalence rates (ASRs) and analyze the secular trends of osteoarthritis (OA) at global, regional, and national levels. The prevalence of OA has increased and diversified by geographic location and affected joint.

• 1 METHODS: Data were derived from the Global Burden of Disease Study 2019.
• 2 ASRs and their estimated annual percentage changes (EAPCs) were used to describe the secular trends of OA according to age group, sex, region, country, and territory, as well as the joints involved.
• 3 RESULTS: Globally, prevalent cases of OA increased by 113.25%, from 247.51 million in 1990 to 527.81 million in 2019.

Understanding this could lead to better treatments, improved diagnostics, or a deeper grasp of how the human body works — benefiting patient care globally.
