SEEK Study - Study on Emergency Health Care Workers' Job Strain Evaluated by Karasek Questionnaire

Emergency health care workers are exposed to job strain - defined by Karasek as a combination of high job demands and low job control. Emergency health care work is a complex interaction between stress due to life-threatening emergencies, overcrowding of the Emergency Department, the lack of sleep, bad food repartition during shifts, and accumulated fatigue. However, the Karasek questionnaire has never been assessed for Emergency Health Care workers. Furthermore, the variation of results during the career has never been assessed. The same measures will be repeated every 5 year to assess long term changes in subjective and objective measures of stress. The study's main objective is the creation of an Emergency Health Care worker's cohort to assess the evolution of the Karasek questionnaire during the follow-up. Secondary objectives are * the evaluation of the food intake before, during and after a nightshift. * the evaluation of other questionnaires
