This paper reports cross-national data concerning back or neck pain comorbidity with mental disorders. We assessed (a) the prevalence of chronic back/neck pain, (b) the prevalence of mental disorders among people with chronic back/neck pain, (c) which mental disorder had strongest associations with chronic back/neck pain, and (d) whether these associations are consistent across countries. Population surveys of community-dwelling adults were carried out in 17 countries in Europe, the Americas, the Middle East, Africa, Asia, and the South Pacific (N=85,088). Mental disorders were assessed with the Composite International Diagnostic Interview, third version (CIDI 3.0): anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, posttraumatic stress disorder, and social anxiety disorder), mood disorders (major depression and dysthymia), and alcohol abuse or dependence. Back/neck pain was ascertained by self-report. Between 10% and 42% reported chronic back/neck pain in the previous 12 months. After adjusting for age and sex, mental disorders were more common among persons with back/neck pain than among persons without. The pooled odds ratios were 2.3 [95% CI=2.1-2.5] for mood disorders, 2.2 [95% CI=2.1-2.4] for anxiety disorders, and 1.6 [95% CI=1.4-1.9] for alcohol abuse/dependence in people with versus without chronic back/neck pain. Although prevalence rates of back/neck pain were generally lower than in previous reports, mental disorders were associated with chronic back/neck pain. The strength of association was stronger for mood and anxiety disorders than for alcohol abuse/dependence. The association of mental disorders with back/neck pain showed a consistent pattern across both developed and developing countries.
The results suggest that mental disorders are important determinants of work role disability and quality of life, often outnumbering the impact of common chronic physical disorders.
Background-Physical morbidity is a potent risk factor for depression onset and clearly increases with age, yet prior research has often found depressive disorders to decrease with age. This study tests the possibility that the relationship between age and mental disorders differs as a function of physical co-morbidity.
Background-Prior studies in the USA have reported higher rates of mental disorders among persons with arthritis but no cross-national studies have been conducted. In this study the prevalence of specific mental disorders among persons with arthritis was estimated and their association with arthritis across diverse countries assessed.
The instrument performed well in the French context. The potential advantages of using the Dominic Interactive (children enjoy the activity, parents approve of it, it is relatively cost-effective, etc.) suggest its applicability in other settings.
The research questions pertaining to mental health are varied and will determine what mental health issues are of interest and the models of work applicable. There need to be more longitudinal studies and consideration of factors which the worker brings to the workplace (psychosocial issues, personality traits), as well as interpersonal issues and consideration of systemic, organizational, political and economic factors, including leadership styles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
