BACKGROUND: @entity239 ( @entity239 ), a @entity1118 condition of unknown aetiology often develops following a traumatic event. @entity239 has been associated with @entity1005 ( @entity1005 ) and @entity308 ( @entity308 ). METHOD: @entity1 seen in a referral clinic (N=571) were evaluated for @entity239 and @entity5815 ( @entity5815 ) criteria. @entity1 completed questionnaires, and underwent a physical examination and a structured psychiatric evaluation. Critical components of the diagnostic criteria of @entity239 (tender points and @entity158 ) and @entity5815 (persistent debilitating fatigue and four of eight associated symptoms) were examined for their relationship with @entity1005 . RESULTS: The prevalence of lifetime @entity1005 was 20% and lifetime @entity308 was 42%. @entity1 who had both tender points and @entity158 had a higher prevalence of @entity1005 (OR=3.4, 95% CI 2.0-5.8) compared with those who had neither of these @entity239 criteria. Stratification by @entity308 and adjustment for sociodemographic factors and chronic fatigue revealed that the association of @entity1005 with @entity239 criteria was confined to those with @entity308 . @entity1 with @entity308 who met both components of the @entity239 criteria had a three-fold increase in the prevalence of @entity1005 (95% CI 1.5-7.1); conversely, @entity239 @entity1 without @entity308 showed no increase in @entity1005 (OR=1.3, 95% CI 0.5-3.2). The components of the @entity5815 criteria were not significantly associated with @entity1005 . CONCLUSION: Optimal clinical care for @entity1 with @entity239 should include an assessment of @entity130 in general, and @entity1005 in particular. This study highlights the importance of considering co-morbid @entity308 as an effect modifier in analyses that explore @entity1005 in @entity1 with @entity239 .
