- Abstract
Objective. To investigate the prevalence of eight common rheumatic diseases in a large Chinese population.Methods. A population-based epidemiological investigation of the prevalence of eight common rheumatic diseases in a suburb of Beijing was conducted in 14 642 individuals. A community-based survey was carried out using a screening questionnaire. Positive responders were included in a clinical and laboratory examination. Diagnosis was based on the criteria of ACR or those used widely in literature.Results. A total of 10 556 inhabitants were interviewed. Forty-three cases of RA were identified with an age-adjusted prevalence of 0.28% (95% CI 0.19%, 0.41%). Gout was diagnosed with a crude prevalence of 0.09% (95% CI 0.05%, 0.17%). Psoriasis was reported in 28 individuals with a prevalence of 0.27% (95% CI 0.18%, 0.38%). This included two cases diagnosed with PsA, resulting in a prevalence of 7.14% (95% CI 0.88%, 23.5%) in psoriasis patients and 0.02% (95% CI 0%, 0.07%) in the general population. Three individuals were identified with SLE, with a prevalence of 0.03% (95% CI 0%, 0.06%). One individual was identified with SSc and the calculated prevalence was 0.01% (95% CI 0%, 0.05%). One case of Behçet's disease was identified, giving a prevalence of 0.01% (95% CI 0%, 0.05%).Conclusion. This large-scale epidemiological survey provides an estimate of the burden of rheumatic diseases in China.
