Chinese Study Reveals Global Rise in Rheumatoid Arthritis Cases

A recent report conducted by a group of Chinese universities and research institutions has revealed a significant global increase in rheumatoid arthritis cases. The study, carried out by universities such as Wuhan, Hong Kong, and Fudan, as well as prestigious hospitals like Peking Union Medical College Hospital and Shenzhen Children’s Hospital, found that the number of people affected by the disease reached 17.9 million in 2021 — a 13% increase compared to 1990.

The study shows that this autoimmune disease is increasingly affecting individuals over the age of 55. However, since 2015, a noticeable rise in cases has also been observed among younger age groups, particularly those between 20 and 54 years old.

Published in the scientific journal Annals of the Rheumatic Diseases, the study analyzed data from 953 global sites between 1980 and 2021. Researchers used artificial intelligence techniques to examine the data, which included information on disease prevalence, affected age groups, and the extent of mobility-related disabilities caused by the condition.

The results revealed a decline of more than 32% in mortality rates due to rheumatoid arthritis between 1980 and 2021. However, the number of patients suffering from movement disabilities caused by the disease nearly doubled between 1990 and 2021. Researchers warn that incidence rates may continue to rise unless effective preventive measures are implemented or accessible treatments are provided for current patients.

Rheumatoid arthritis occurs when the immune system attacks the tissues surrounding the joints, leading to severe inflammation, pain, and difficulty moving—significantly impacting patients’ quality of life.
