OBJECTIVE: To study the incidence of @entity32 in a defined population in Finland. METHODS: We collected data for the year 2000 on a population of 87,000 inhabitants of Kuopio, Finland, of whom 20% were < 16 years of age. Information about the study was given through a local newspaper, and subjects attended one health center and 2 local hospitals for study. Inclusion criteria were that subjects have at least one peripheral joint with @entity603 or signs of @entity32 in sacroiliac, glenohumeral, or hip joints on the first visit. Incidence rates were calculated according to the diagnosis on the first visit, except for @entity1 , for whom diagnoses were established after 3 months' followup. RESULTS: A total of 188 adult incident cases (138 @entity1 , 50 @entity1 ) and 11 @entity1 (8 @entity1 , 3 @entity1 ) satisfied the inclusion criteria. The incidence of all @entity625 was 230/100,000 (95% confidence interval 198.9-263.9) for the whole population; 271/100,000 (95% CI 233.7-312.7) for adults and 64/100,000 (95% CI 31.7-113.8) for @entity1 . Among adults the annual incidence of @entity309 ( @entity309 ), @entity1691 ( @entity1691 ), @entity5144 ( @entity5144 ), @entity625 ( @entity625 ), other @entity5145 ( @entity5145 ), connective tissue disease (CTD), @entity625 , @entity5414 , and undifferentiated @entity625 were 36, 7, 23, 10, 13, 9, 19, 7, and 149/100,000, respectively. The mean age at diagnosis was 49.4 +/- 16.3 years for all cases of @entity625 among adults, about the same for both @entity1 and @entity1 . The mean age at diagnosis was 59.7 years in @entity309 , 31.5 years in @entity1691 , 48.7 years in @entity5144 , 38.0 years in @entity625 , 36.5 years in other @entity5145 , 36.1 years in CTD, 65.0 years in @entity625 , 53.3 years in @entity5414 , and 48.3 years in undifferentiated @entity625 . Four of 11 @entity1 had @entity4932 ( @entity4932 ). The incidence of @entity4932 was 23/100,000 in the population < 16 years of age. Of the remaining cases, 3 children had antibodies against @entity778 and 4 had a transient monoarthritis. CONCLUSION: The overall incidence of @entity625 among adults was slightly higher than previously reported from Finland. The incidence rates in the @entity1 population are in agreement with previous figures. These data are useful in planning the provision of health care.
