OBESITY-RELATED BURDEN OF OSTEOARTHRITIS OF KNEE AND HIP

Osteoarthritis (OA) is a leading cause of disability and a source of societal costs among older adults, especially with an increasingly obese population. Few studies have investigated the burden of knee and hip OA due to high body mass index (BMI). Therefore, this study aimed to systematically summarize the trends of knee and hip OA due to high BMI in China and the USA 1990–2019.

Methods: Global Burden of Disease Study 2019 data were used to estimate age-standardized prevalence, disability-adjusted life years (DALYs) rates of knee and hip OA, and burden of knee and hip OA due to high BMI by sex. Joinpoint regression analysis was used to determine temporal trend changes.

Results: Trends in DALYs rates of knee OA due to high BMI have shown a steady and large increase in China, while USA trends first showed an increase followed by a large decrease 200–2005 and finally a steady increase. Trends in DALYs rates of hip OA due to high BMI have shown a steady and large increase in both men and women in both countries 1990–2019. Age comparison data are also available for both countries.

Conclusions: The burden of knee and hip OA due to high BMI is substantially increasing in China and the USA in recent years. Researchers and health policy makers should assess changing patterns of high BMI on the burden of OA and devise corresponding weight-control strategies.
