Lifestyle Risk Factors Associated with Fatigue in Graduate Students

Background/PurposeFatigue is not only common in clinical patients but is also prevalent in the healthy population. This study aimed to estimate the prevalence rate of fatigue and identify significant risk factors among graduate students.MethodsHealth check-ups were carried out on graduate students who were newly admitted to the National Taiwan University in this cross-sectional study. A total of 1806 attendees (response rate, 84%) agreed to participate in the fatigue survey, which used the Checklist Individual Strength questionnaire (CIS-20). The modified Baecke's questionnaire was used to quantify the intensity of physical activity.ResultsThe prevalence rates of fatigue were 45.8% for males and 48.9% for females. Regular meal (odds ratio [OR], 0.69) and exercise habits (OR, 0.68), insomnia (OR, 2.23), greater amount of sleeping time (OR, 0.7), identity (doctorate vs. master students; OR, 0.61), and chronic disease history (OR, 1.61) were statistically significant predictors for fatigue. Intensity of physical activity was a protective factor (ORs, 0.72, 0.50 and 0.36 in the 2nd, 3rd and top quartiles vs. 1st quartile;p < 0.001).ConclusionA high prevalence rate of fatigue among the graduate students was demonstrated. The risk factors among young adults are not only related to current chronic disease and insomnia but are also attributed to the lack of physical activity.
