Abstract Background Only a few studies have analyzed the effects of physical and psychiatric conditions on the risk of chronic fatigue syndrome (CFS). Therefore, the goal of this exploratory case-control study was to investigate the associations of physical and psychiatric conditions with CFS in almost 19 800 adults from Germany. Methods This study included patients diagnosed for the first time with CFS in one of 1238 general practices in Germany between 2010 and 2017 (index date). Controls without CFS were matched (1:1) to cases with CFS by sex, age, index year, and practice. Physical and psychiatric conditions diagnosed in the year prior to the index date were included if they were present in at least 3% of patients with CFS. Associations between physical and psychiatric conditions (33 potential independent variables) and CFS (dependent variable) were analyzed in an adjusted conditional logistic regression model, and physical and psychiatric disorders were included in the model using forward stepwise selection. Results This study included 9896 cases with CFS and 9896 controls without CFS [65.1% women; mean (standard deviation) age 49.5 (18.3) years]. Seven conditions were associated with CFS in the adjusted regression model. The disorders displaying the strongest relationship with CFS were cancer [odds ratio (OR) = 2.57, 95% confidence interval (CI) = 2.24–2.95], sleep disorders (OR = 1.88, 95% CI = 1.66–2.12) and depression (OR = 1.77, 95% CI = 1.61–1.95). Conclusions Cancer, sleep disorders, and depression were strongly and positively associated with CFS. Additional studies are needed to gain a better understanding of the mechanisms underlying these relationships.

Background: What adolescents think about symptoms and what they do in response could contribute to fatigue maintenance. We compared the cognitive and behavioural responses of adolescents and their parents with chronic fatigue syndrome (CFS; N = 121) and asthma ( N = 27) and explored the predictive value of these variables on fatigue and functioning in CFS. Method: Consecutively referred adolescents with CFS were recruited. Questionnaires, completed by adolescents and parents, assessed fatigue, functioning, mood and cognitive and behavioural responses to symptoms. Age-matched adolescents with asthma completed the same questionnaires. Adolescents with CFS completed questionnaires again approximately 3 months later. Results: Adolescents with CFS scored higher on all unhelpful cognitive and behavioural subscales than adolescents with asthma. Parents’ cognitions about their child’s symptoms were associated with adolescent’s own cognitions. Unhelpful cognitive and behavioural responses, particularly, damage beliefs, predicted subsequent fatigue in CFS, and all-or-nothing behaviour, catastrophising and damage beliefs predicted subsequent physical functioning. Conclusion: Unhelpful cognitive and behavioural responses to symptoms appear to be particularly prominent in adolescents with CFS. There is some consistency but not a perfect match between cognitive and behavioural responses to symptoms reported by adolescents and their parents. These responses could be contributing to fatigue maintenance and disability.
