Are trends in work and health conditions interrelated? A study of Swedish hospital employees in the 1990s.

Swedish hospital personnel were followed over an 8-year period, characterized by staff redundancies and restructuring processes. Self-rated and administrative data sets from 1994 to 2001 allowed for studying long-term consequences of organizational instability for staff health and work conditions. The aim was to identify, on a work-unit level, trends in work and health conditions and their interdependence. Regression analysis showed a downward trend in mental health and an upward trend in long-term sick leave. Increasing trends of work demands were accompanied by deteriorating mental health, and decreasing time to plan work showed the strongest association with increasing long-term sick leave. Job satisfaction and support were decreasing. A stable short-term sick leave rate over years related to lack of support. Copyright 2005 APA, all rights reserved.
