Le syndrome de fatigue chronique est une maladie agnogène à l’échelle mondiale. Les infirmières courent un risque élevé de syndrome de fatigue chronique. Cependant, aucune recherche n’a été effectuée pour examiner les liens entre la violence au travail, le soutien organisationnel et le stress professionnel et le syndrome de fatigue chronique chez les infirmières chinoises. Cette étude visait à examiner les effets de ces facteurs sur le syndrome de fatigue chronique dans ce groupe professionnel. Conception transversale. Tous les participants ont volontairement rempli un questionnaire d’enquête.
Aims Chronic fatigue syndrome is an agnogenic disease worldwide. Nurses are at a high risk of chronic fatigue syndrome. However, no research has been done to examine the associations of workplace violence, organizational support, and occupational stress with chronic fatigue syndrome among Chinese nurses. This study aimed to examine effects of these factors on chronic fatigue syndrome in this occupational group. Design Cross-sectional. All participants voluntarily completed a questionnaire survey. Methods The study was conducted in Liaoning province from December 2017–January 2018. Self-administered questionnaires were distributed to 1,200 nurses, including Effort-Reward-Imbalance, Workplace Violence Scale, Survey of Perceived Organizational Support, together with age, gender, marital status, education levels, physical activities, job rank, monthly income, and weekly working hours. Complete responses were obtained from 1,080 (90%) participants. Chronic fatigue syndrome was diagnosed by doctors according to the Centers for Disease Control and Prevention criteria. Multivariable logistic regression was performed to examine these independent risk factors. Results The prevalence of chronic fatigue syndrome was 6.76%. The results of logistic regression analysis showed that nurses who experienced serious higher levels of overcommitment, workplace violence and less organizational support were more likely to be classified as chronic fatigue syndrome. Conclusion There was a high prevalence of chronic fatigue syndrome. Lower workplace violence, more organizational support and lower overcommitment could be effective resources for reducing chronic fatigue syndrome. Impact Workplace violence, organizational support, and occupational stress were related to chronic fatigue syndrome, which helped to explain why Chinese nurses suffered higher prevalence of chronic fatigue syndrome. Overcommitment explained chronic fatigue syndrome better than Effort/Reward Ratio, so intrinsic stress played a more critical role than extrinsic stress in chronic fatigue syndrome. Chinese nurses suffered serious sleep disorders and impairment of concentration and memory. These symptoms might also attribute to serious occupational stress, unsafe and unsupportive working environment. Creating a safe and supportive working environment, relieving intrinsic occupational stress should be considered as an institutional strategy to early prevent chronic fatigue syndrome.
