[Occupational risk stress in shift workers]

Aim of our study was to assess the stress risk at work in a group of nurses. 197 workers (nurses, auxiliary, physiotherapists, midwives and technicians of laboratory) were enrolled divided in two sets respectively of 100 people (subset A) with daily and nightly shifts and 97 (subset B) only daily workers. The mean age was 43.29 years (DS +/- 8.13) in subset A and 46.85 years (DS +/- 7.48) in subset B. For the survey S-90, a questionnaire composed by 90 items faces to frame some of the possible factors of risk has been used and the relative effects on health's state induced by the occupational stress were analyzed. The results show a possible greater risk of daily sleepiness in workers with nightly job. The majority of hypertension workers in subgroup B could depend more on the elevated mean age of this sample. Although a greater perception of the psychological load has been found, statistically meaningful association between the insurgence of gastrointestinal symptoms and shift was not showed.
