Objectives: Health care providers, especially registered nurses (RNs), are a professional group with a high risk of musculoskeletal pain (MSP). This longitudinal study contributes to the literature by describing the prevalence and change in MSP, work-related factors, personal factors, self reported pain, disability and sick leave (> 7 days) among RNs working in a Swedish hospital over a three-year period. Further, results concerning prediction of pain, disability and sick leave from baseline to a three-year follow-up are reported. Method:  In 2003, a convenience sample of 278 RNs (97.5% women, mean age 43 years) completed a questionnaire. In 2006, 244 RNs (88% of the original sample) were located, and 200 (82%) of these completed a second questionnaire. Results: Logistic regression analyses revealed that pain, disability and sick leave at baseline best predicted pain, disability, and sick leave at follow-up. The personal factors self rated health and sleep quality during the last week predicted pain at follow-up, while age, self rated health, and considering yourself as optimist or pessimist predicted disability at follow-up, however weakly. None one of the work- related factors contributed significantly to the regression solution. Conclusions: The results support earlier studies showing that a history of pain and disability is predictive of future pain and disability. Attention to individual factors such as personal values may be needed in further research.
