Fatigue and associated factors in hemodialysis patients in Taiwan.

The number of patients suffering from end-stage renal disease is increasing rapidly around the world, including in Taiwan. Hemodialysis (HD) patients report fatigue as a major stressor. The purpose of this correlational study with systematic sampling was to explore fatigue and associated physiological, psychological, and situational factors in 119 Taiwanese HD patients. Results indicate that levels of fatigue were mild. Three variables (gender, employment, and depression) had a significant impact on fatigue. Some differences in physiological factors by depression, gender, and employment were found. Stepwise regressions showed that depression, age, and urea reduction ratio were significant predictors for overall fatigue and two of its dimensions. Some relationships from the theory of unpleasant symptoms were supported. Copyright 2006 Wiley Periodicals, Inc.
