Abstract
Background: Female nurses are highly susceptive to night shift work. Age, nap times during night shift, physical activity level, and lifestyles strongly associated with fatigue at night shift; however, a comprehensive analysis of these factors including psychological research could not be conducted. Purpose: The purpose of this study is to prove the risk factors for fatigue of medical-surgical female nurses having night shift working based on the data of demographics, lifestyles, subjective symptoms, and performance status from pre night shift to post-holiday. Methods: This cross-sectional study was conducted on 97 Japanese female night shift nurses. The data of age, body mass index, clinical experience years, lifestyles, and nap time during night shift were collected. Total steps, energy expenditure, and subjective symptoms; drowsiness, instability, uneasiness, dullness, and eye strain had been continuously measured and evaluated from pre night shift to post-holiday. Nurses who recovered from fatigue were assigned to a recovery group; other nurses were assigned to a non-recovery group based on improvements in total five subjective symptoms between pre night shift and post-holiday. Results: Age, body mass index, nap time length during night shift, clinical experience years, performance status, and lifestyles were not different between recovery group and non-recovery group. Logistic regression analysis showed that drowsiness and eyestrain are significant risk factor for fatigue at night shift. Adjusted odds ratio (95% confidence interval) for fatigue in medical-surgical female nurse having night shift were 2.04 (1.36-3.01) in drowsiness and 2.03 (1.30-3.18) in eyestrain (P
Highlights
Shift work disturbs the natural circadian rhythms, and nurses suffer from an unfavorable condition known as shift lag and desynchrony [1]
We divided the subjects into two groups; recovery group and non-recovery group based on improvements in fatigue feelings between pre night shift and post-holiday
The exposure to workplace related stressors is a predictor of cardiovascular diseases and higher systolic blood pressure, and psychological detachment from work environment of nurse who engaged in night shift contributes to recover from subjective symptoms [21]
Summary
Shift work disturbs the natural circadian rhythms, and nurses suffer from an unfavorable condition known as shift lag and desynchrony [1]. Factors influencing fatigue of nurses have been studied extensively and work-related factors, psychological factors, and demographic factors have been recognized as contributing to nurse fatigue [2, 3, 4]. It is important for night shift workers not to perturb biological rhythms. Taking a nap during the night shift has been suggested as an effective way to prevent fatigue or other complaints related to shift work[6]. Nursing is a profession that typically involves shift work as nurses are required to provide continuous health care for the patients [7]
