Sex- and age-specific incidence of autoimmune rheumatic diseases in the Chinese population: A Taiwan population-based study

ARDs are three to four times more common among women than among men in the Chinese population of Taiwan. The incidence of RA was the highest, followed by Sjögren's syndrome and SLE, while the incidence of Behçet disease was the lowest in this study. This nationwide, population-based, longitudinal epidemiological study of ARDs in Taiwan provides data for future global comparisons and may provide clues as to the etiology of these diseases.
