Global and Regional Temporal Changes in Cross-Country Inequalities of Site-Specific Osteoarthritis Burden, 1990 to 2021.

ABSTRACT:

Objective

This study examined the global and regional temporal changes in cross-country inequalities of site-specific osteoarthritis (OA) burden from 1990 to 2021.

Methods

Age-standardized years lived with disability rates (ASYRs) for site-specific OA across 204 countries and territories were obtained from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021. The slope index of inequality (SII) and the concentration index (CCI) were calculated to quantify the absolute and relative cross-country inequalities. Average annual percent change (AAPC) was used to assess the temporal changes.

Results

From 1990 to 2021, the ASYR of OA increased regardless of the joint affected globally. The SII of total OA exhibited an improving cross-country inequality a
