Abstract

Objectives to estimate the prevalence of rheumatoid arthritis (RA) and spondyloarthropathy (SpA) in the capital town of Serbia, Belgrade

Methods translation and cross-cultural adaptation of the original RA and SpA telephone detection Questionnaire to Serbian language was successful, preserving the validity of the original tool (1). Prevalence was estimated on a systemic sample - using every 100th number from the telephone list. The validated detection Questionnaire was administered in a first call, performed by 10 trained patient-interviewers. A second call was done by rheumatologist, who confirmed RA or SpA diagnosis on the basis of the patient records. In case of uncertain diagnosis, the patient was invited for clinical examination.

Results A total of 5361 telephone numbers was called. After the exclusion of second residents, business places and children, 4340 persons were interviewed with a response rate of 61,8%. The second, rheumatologist call was received by 389 subjects, of whom 53 were clinically examined. A total of 14 RA cases and 9 SpA cases were detected, with crude prevalence rate of 0.53% (95% CI:0,25-0,80) for RA and 0.34% (95% CI:0,12-0,56) for SpA. The standardised prevalence rate according to Serbian census population data for Belgrade was 0,38% (95% CI:0,18-0,58) for RA and 0,28% (0,10-0,46) for SpA.

Conclusions Crude prevalence rate for RA in the present study (0,53%) differs from that obtained earlier (2). Interestingly, using common classification criteria and a unique investigation method, the standardized RA and SpA prevalence rates for Belgrade (0,38% and 0,28%, respectively) were in the same range with those observed in France (3,4).
