SUMMARY:

Sleep is a physiological state that occurs cyclically in most species. Human beings, for example, spend more than a third of their lives sleeping. However, not all humans are able to dedicate that one third to sleep for several reasons. One of these reasons is the implementation of working in shifts and because of it, they are forced to reduce their total sleep time according to the demands of their job. This research aims to study the pattern of the sleep/wake cycles, their regulation mechanisms (homeostatic and circadian components), moods, and fatigue of nurses who are chronically submitted to shift work. METHODOLOGY: This is a cross-sectional study, with a quantitative approach and observational design, with thirteen evaluation measures, conducted with 47 nurses assigned to the “Serviço de Atendimento Móvel de Urgência - SAMU” (Mobile Emergency Service) in Natal and Greater Natal area. To know the sleep/wake cycle patterns, The Pittsburgh Sleep Quality Index (PSQI), the Sleep Habits Questionnaire, the Epworth Sleepiness Scale (ESS), and the Sleep Diary, will be used (as subjective measures) and actigraphy (L5, M10, IV and AR) and polysomnography (F3-F4, C3-C4, O1-O2, Ad-Ae, OCG, EMG, ECG, respiratory movements and SPO2) will be used as objective measures. The Horne and Ostberg’s Morningness-eveningness Questionnaire (MEQ) and the Munich ChronoType Questionnaire (MCTQ) will be used to identify the chronotype and social jet lag, in addition to specific questionnaires to assess the socio-economic-demographic situation and the fatigue and depression levels. Nonprobability sampling was used because it was decided to make the subjects' availability more flexible. PRELIMINARY RESULTS: The preliminary results were based on data collected from actigraphy (38 subjects), online survey application (47 subjects answered), and polysomnography (25 subjects). The application of the questionnaires in the sample produced a set of data with 47 participants quantified in 246 random variables. The sample, non-probabilistic and for convenience, is characterized by 34 women and 13 men, which correspond to about 72% and 28% respectively. All subjects have been working in shifts for at least 5 years. Regarding mood states, it was observed that nurses are more depressed than anxious, although both scores were high. The most fatigued, with higher levels of sleepiness (75% for both situations), with worse self-reported quality of sleep (91.3%), and low IS values, however, they were only attributed to nurses who are submitted to shift work from 5 to 7 years, regardless of the type of shift. From the actigraphy data, it was observed that the IS values tend to be lower in this last group as well, showing an unstable rhythm among the participants. Still in this segment, a lower IV was observed when the individual works on a day shift or alternated in another employment relationship besides SAMU. Finally, it was observed that these professionals express an unstable rhythm, poor sleep quality, characterized by high levels of depression and anxiety.
