Abstract
OBJECTIVES: This study aimed to determine the prevalence of gout in a general Turkish population, according to the American College of Rheumatology (Wallace) criteria proposed for gout classification. METHODS: This study was conducted in two districts of Izmir Province in Turkey, and involved 2835 subjects of ≥ 20 years of age. In the first stage, face-to-face interviews were performed at the subjects' registered households. In the second stage, subjects who gave positive answers in the screening questionnaire were invited to the hospital for a full examination, which included a detailed medical history, medication use and blood tests. RESULTS: A total of 2887 subjects were contacted, and complete interviews were obtained for 2835 (1551 women, 1284 men). A total of 312 subjects (227 women, 85 men) reported experiencing a short period of joint pain accompanied by swelling, redness or reduced range of movement, and 247 (79%) of these patients underwent a detailed clinical examination in the hospital. Gout was diagnosed in 11 patients (8 men, 3 women). We found minimum age- and sex-adjusted prevalence rates of gout of 0.31% (95% CI: 0.16-0.61) in subjects of ≥ 20 years of age, and 0.72% (95% CI: 0.37-1.24) in subjects of ≥ 40 years of age. CONCLUSIONS: Our data suggest that the estimated prevalence of gout (0.31%) is lower than the previously published estimated prevalence of rheumatoid arthritis (0.36%) in the same study population (14 definite rheumatoid arthritis cases among the 2835 subjects).
