| Research Abstract |
The purpose of our study was to investigate work stress factors associated with the chronic fatigue syndrome (CFS) in Japanese female workers. The data collection instrument in our study was mainly composed of work conditions and subjective symptoms called the Brief Job Stress Questionnaire, and the degree in severity of fatigue related to CFS. From October in 2004 to June 2005, 992 questionnaires were delivered and 752 surveys were returned. In order to measure of 8-hydroxydeoxyguanosine as an end-product of oxidative DNA injuries, urine samples were also collected from 199 participants. Statistical analysis was carried out using JMP software (SAS Institute, Tokyo). In the diagnostic criteria of chronic fatigue syndrome, 64 female respondents complained physical exhaustion although they were able to work and carry out ordinary social lives. Contrary to the response by male respondents, female workers tended to complain of tiredness in other questionnaires depicting CFS. The result of

the Brief Job Stress Questionnaire presented that the more female workers claimed subjective symptoms, such as weariness, headaches, and stiffness of their neck than male workers (P<0.001). In contrast to the result of non-nurses group, 24% of nurses significantly carried a burden of quality and quantity of workload (P<0.001). In subjective symptoms, the result indicated that nurses significantly felt weariness, anxiety, and depression in addition to back and joint aches and insomnia. The result of urinary analysis for oxidative DNA injuries indicated that there were significantly increased amount of 8-OH-dG among nurses from the age 20 to 30 in contrast to the result of the same age group of nun-nurses. The mean of urinary 8-OH-dG in nurse who were engaged in the shift work also exhibited much higher levels than the results of part time female workers. In conclusion, the result of our study revealed that female workers were more vulnerable to work stress than male workers. The result also indicated that shift work is one of the contributing factors for nurses to make their health condition to an exhaustive status. Less
