ABSTRACT Six-hundred-seven employees in 3 metal industry plants were studied for depressive and distress symptoms, musculoskeletal symptoms, and findings in the musculo-skeletal system made by a physiotherapist. Measurements were made 3 times at 5-year intervals. The mean distress and depressive symptom scores of the first 2 examinations predicted the change in several musculo-skeletal symptom measures during the second 5-year period, when the effects of age and occupational class were accounted for in multiple regression analysis. They also predicted the development in clinical musculoskeletal findings in men. The proportions of variance explained by the depressive and distress symptoms were modest in magnitude. Analogous analyses were made with reference to the reverse temporal sequence: musculoskeletal disorders were considered as predating the development in depressive and distress symptoms. The musculoskeletal symptom scores were associated with the change in the stress symptoms in men, as did the clinical findings in the neck-shoulder and low back regions. None of the musculoskeletal morbidity scores predicted the change in the depressive symptoms in either sex. We conclude that depressive symptoms predict future musculoskeletal disorders, but not vice versa, whereas the association of stress symptoms and musculoskeletal disorders is reciprocal.

    ABSTRACT: Objectives: To determine the prevalence of facial pain and to examine the hypothesis that symptoms are associated with socio-demographic, dental, adverse psychological factors and pain elsewhere in the body. Material and Methods: Cross-sectional population data were obtained from UK Biobank ( study which was conducted in 2006 -2010 and recruited over 500,000 people. Results: The overall prevalence of facial pain (FP) was 1.9% (women 2.4%, men 1.2%) of which 48% was chronic. The highest prevalence was found in the 51 -55 age group (2.2%) and the lowest in the 66 -73 age group (1.4%). There was a difference in prevalence by ethnicity (0.8% and 2.7% in persons reporting themselves as Chinese and Mixed respectively). Prevalence of FP significantly associated with all measures of social class with the most deprived and on lowest income showing the highest prevalence (2.5% and 2.4% respectively). FP was more common in individuals who rated themselves as extremely unhappy, had history of depression and reported sleep problems. Smoking associated with increase in reporting FP while alcohol consumption had inverse association. FP associated with history of painful gums, toothache and all types of regional pain. Conclusions: This is the largest ever study to provide estimates of facial pain prevalence. It demonstrates unique features (lower prevalence than previously reported) and common features (more common in women) and confirms multifactorial aetiology of facial pain. Significant association with psychological distress and a strong relationship to pain elsewhere in the body suggests that aetiology is not specific to this regional pain.

    ABSTRACT: Previous studies have shown that depressive and anxiety disorders are strongly related to somatic symptoms, but much is unclear about the specificity of this association. This study examines the associations of specific depressive and anxiety disorders with somatic symptoms, and whether these associations are independent of comorbid depressive and anxiety disorders.Methods Cross-sectional data were derived from the Netherlands Study of Depression and Anxiety (NESDA). A total of 2008 persons (mean age: 41.6 years, 64.9% women) were included, consisting of 1367 patients with a past-month DSM-diagnosis (established with the Composite International Diagnostic Interview [CIDI]) of depressive disorder (major depressive disorder, dysthymic disorder) and/or anxiety disorder (generalized anxiety disorder, social phobia, panic disorder, agoraphobia), and 641 controls. Somatic symptoms were assessed with the somatization scale of the Four-Dimensional Symptom Questionnaire (4DSQ), and included cardiopulmonary, musculoskeletal, gastrointestinal, and general symptoms. Analyses were adjusted for covariates such as chronic somatic diseases, sociodemographics, and lifestyle factors.ResultsAll clusters of somatic symptoms were more prevalent in patients with depressive and/or anxiety disorders than in controls (all p < .001). Multivariable logistic regression analyses showed that all types of depressive and anxiety disorders were independently related to somatic symptoms, except for dysthymic disorder. Major depressive disorder showed the strongest associations. Associations remained similar after adjustment for covariates.Conclusion This study demonstrated that depressive and anxiety disorders show strong and partly differential associations with somatic symptoms. Future research should investigate whether an adequate consideration and treatment of somatic symptoms in depressed and/or anxious patients improves treatment outcomes.
