BACKGROUND: Increased demands for @entity146 services and increased rates of sickness absence for @entity308 have raised the question of the occurrence of @entity146 in Norway, and whether there is in fact a rising incidence rate. METHODS: Between 1989-1991, 2015 and 617 @entity1 participated in a two-phase population study. Phase I comprised screening by the Hopkins Symptom Check List 25 items (HSCL-25), and phase II a diagnostic interview by the @entity13875 ( @entity13875 ), including report of date (year) of the first occurrence of any symptoms, and any consequent diagnosis: RESULTS: A symptom score of 1.75 or more was found in 19.8% of the @entity1 and 9.3% of the @entity1 by the HSCL-25. @entity308 , @entity148 by @entity13875 was found in 21.5% of the @entity1 and 11.5% of the @entity1 . The incidence rate increased significantly from 3.3 to 12.8 per 1000 @entity1 years from 1930 to 1991. The incidence rate in the year before the interview was 42.6 per 1000 @entity1 years. Age of onset became lower. More @entity1 became ill, but the illness seemed to last longer in @entity1 . A major problem in comparing results between studies is the different concepts and operationalisations of @entity146 , and the varying time periods given for estimates. CONCLUSION: The findings provide evidence of @entity146 being a rising and major health problem, but the role of recall bias must be further investigated.
