Increasing burden of hip osteoarthritis in the Middle East and North Africa (MENA): an epidemiological analysis from 1990 to 2019.

Abstract

The hip is the second most affected joint in osteoarthritis (OA), diagnosed annually worldwide. This is the first study presenting the epidemiology of hip OA in the Middle Eastern and North African countries from 1990 to 2019. This study was performed based on the analysis of global burden of disease (GBD) study data. Epidemiological indices including prevalence, incidence, and years lived with disability (YLD) were compared in all 21 countries located in Middle East and North Africa (MENA) region during 1990 to 2019. The prevalence of patients with hip OA in MENA increased 3.1-fold, from 0.40 to 1.28 million during the study period. Hip OA accounted for about 74.46 thousand (95% UI 56.64-94.92) incident cases in MENA at 2019. It was found that Qatar had the highest age-standardized prevalence in both 1990 (0.33% [0.25-42]), and 2019 (0.40% [0.30-0.50]) in MENA. Oman showed the greatest relative increase (around 50.10%) in age-standardized prevalence of hip OA, whereas Iraq showed the lowest relative increase (around 9.94%) compared with other MENA countries. Hip OA prevalence and YLD have both increased in MENA over the last three decades. The region's rapidly increasing burden of hip OA emphasizes the need to focus on OA prevention strategies especially in Qatar, Kuwait, Saudi Arabia, and UAE.
