Prolonged fatigue and nutritional intake among Japanese workers

本研究的目的是探讨日本工人长期疲劳和营养摄入之间的关系。疲劳状态，生活方式，营养摄入和健康状况的受试者进行了评估问卷和心率变异性（HRV）的加速度体积描记法。主观疲劳程度较强的男工心率变异性与疲劳程度显著相关，而女工心率变异性与疲劳程度无关。营养摄入量与女工疲劳有显著相关性，而与男工无显著相关性。目前的研究表明，疲劳的生物学状态或与疲劳相关的因素可能是不同的男性和女性工人在日本。

The aim of this study was to examine the relationship between prolonged fatigue and nutritional intake among Japanese workers. Fatigue status, life-styles, nutritional intake, and health status of the subjects were assessed by questionnaires and heart rate variability (HRV) by acceleration plethysmography. HRV was significantly associated with fatigue in male workers with strong subjective fatigue,but not in female workers. Nutritional intake was significantly associated with fatigue in female workers but not in male workers. The current study suggests that biological status of fatigue or factors associated with fatigue may be different between male and female workers in Japan.
