Burnout and risk of regional musculoskeletal pain-a prospective study of apparently healthy employed adults

Musculoskeletal pain (MP) is highly prevalent in the working population, often resulting in chronic disability. Work stress has been shown to be important in the aetiology of MP. Burnout is a unique affective response to chronic exposure to stress and might predict subsequent development of MP. To date, however, all studies in this area have been based on a cross-sectional design, which prevents determining the direction of causality. This prospective study tested the extent to which baseline levels of burnout predict the onset of regional neck/shoulder and/or low back pain, in apparently healthy individuals. The participants were composed of 650 employed men and women who underwent follow-up for 3-5 years. During the follow-up Period, 116 workers (17.8%) developed musculoskeletal pain. Logistic regression results indicated that burnout symptoms were associated with a 1.67-fold increased risk of MP [95% confidence interval (CI) = 1.14-1.87], even after adjusting for possible confounding variables (such as white- or blue-collar jobs). Those exhibiting high burnout levels, compared with others, showed higher relative risk of MP [odds ratio (OR) = 2.45, 95%CI = 1.35-4.45]. It was concluded that burnout might be a risk factor for the development of musculoskeletal pain in apparently healthy individuals. Copyright (C) 2009 John Wiley & Sons, Ltd.
