The aim of this study was to estimate the prevalence of self-reported musculoskeletal symptoms in a sample of Norwegian nurses, and to investigate whether work characteristics, demographic factors, depression, anxiety, insomnia, and shift work disorder were associated with such symptoms. A total of 1875 nurses (67.5% response rate) completed a questionnaire which surveyed frequency of musculoskeletal symptoms in different body regions during the last year, work characteristics, including shift schedule and number of night shifts and quick returns (QRs), demographic factors including age, sex, marital status, children living at home, percentage of full-time equivalent, and symptoms of depression, anxiety, insomnia, and shift work disorder. Data were analyzed with chi-square tests and crude and adjusted logistic regressions. Over half of the nurses (53.8%) reported musculoskeletal symptoms in one or more body regions. Compared with day only, two-shift rotation was associated with musculoskeletal symptoms (adjusted OR 1.61, 95% CI 1.20-2.14), whereas three-shift rotation and night only were not. Neither number of night shifts nor QRs were associated with musculoskeletal symptoms. Probable anxiety (aOR 2.23, 1.73-2.87), depression (aOR 2.08, 1.44-3.00), insomnia (aOR 2.45, 1.95-3.09), and shift work disorder (aOR 1.61, 1.28-2.02) were associated with musculoskeletal symptoms. Further research is necessary to elucidate causality.
