[Analysis of cognitive function and sleep of nursing staff on different shift work]. / Análise das funções cognitivas e sono na equipe de enfermagem nos turnos diurno e noturno.

The aim of this study was to analyze short-term memory, attention and sleep patterns of the nursing staff working night and day shifts. Study participants were 109 subjects in a hospital in Minas Gerais working on the day shift (n = 68) or night shift (n = 41). Data collection was performed using the Sleep Diary and WAIS-III Test Battery. The results showed a significant difference for the quality of sleep of those on night shift work (p < 0.0001; ANOVA). The subjects on the day shifts performed better on the Digit Symbol with a significant difference (p = 0.0008; Mann-Whitney test). In conclusion, the quality of sleep of the group on the night shift showed lower averages compared with those on the day shifts, although they had greater total sleep. The level of attention showed to be best for the group on the day shift work.

[Sleep patterns and fatigue of nursing students who work]. / Padrão de sono e sonolência do trabalhador estudante de enfermagem.

It has been observed there is currently a growing interest in developing research regarding the sleep patterns of workers who must wake up very early or who work nights. Therefore, the objective of this study was to identify the levels of fatigue and the sleep patterns of nursing students who study during the day and work at night. Participants were thirty students who completed the Epworth Sleepiness Scale and Sleep Journal for thirty days. It was found that sleep duration was longer among men compared to women on days off work, and when on vacation from school compared to the regular school period. Participants showed high levels of fatigue and sleepiness, characterized by the incidence of excessive daytime sleepiness. In conclusion, night workers who endure sleep deprivation have additional wake hours due to studying, thus causing high levels of fatigue, which may harm their performance at school and at work.

[Stress and sleep quality of nurses working different hospital shifts]. / O estresse e qualidade de sono do enfermeiro nos diferentes turnos hospitalares.

The purpose of this study was to analyze the relationship between stress and sleep quality among nurses who work on different hospital departments during morning, afternoon and night shifts. This study was performed in a hospital in Campinas, Sao Paulo. Data collection was performed using the Bianchi Stress Scale modified (BSSm) and Pittsburgh Sleep Quality Index (PSQI). Study participants were 203 registered nurses, mostly aged between 40 and 49 years. Results show there is a significant correlation between stress and sleep (Spearman Analysis; r = 0.21318; p = 0.0026). Nurses working morning shifts showed higher stress levels (p = 0.030; Chi-square Test,) and poor sleep quality. In conclusion, stress level was a factor directly correlated to sleep, showing that the higher the stress score, the worse the quality of sleep.

This study aimed to observe the architecture of day sleeping after a night of work, and the characteristics of the sleep-wake cycle in nurses working in different shifts. The study was performed at the Hospital de Clínicas da Faculdade de Medicina de Ribeirão Preto, USP. The sleep-wake cycle was evaluated through the sleep diary in (n = 36) subjects, with an average age of 30 years. Of these, only five performed polysomnography measurements at the Sleep Laboratory. Subjects presented better night sleep and the polysomnography recordings identified short periods of day sleep with incomplete cycles. Subjects woke up many times, which characterizes poor sleep efficiency.

[Circadian variability at oral, tympanic and axillary temperature in hospitalized adults]. / Variabilidade circadiana da temperatura oral, timpânica e axilar em adultos hospitalizados.

The aim of this study was to measure the circadian variability of patients' temperature in the eardrum, oral, and armpit positions considering the measurement angle. The study was carried out at the State University of Campinas' Clinics Hospital (HC Unicamp), a school hospital in the city of Campinas, State of São Paulo. Temperatures were taken in the Cardiology, Adult General Clinic and Gastric infirmaries every two hours in two consecutive days, from the time patients woke up until 10 PM. The results show a significant difference, p-value = 0.0001, between the morning and afternoon periods compared to the evening period. The Tukey test has also showed a difference. It was observed that the measurement in the eardrum position resulted in higher temperatures compared to the other positions, thus confirming data in the international literature. The circadian variability eardrum temperature was similar to the measurements of the oral temperature during the patients' awaked period.

Quality of Life, Sleep, and Health of Air Traffic Controllers With Rapid Counterclockwise Shift Rotation.

Rotating shiftwork is common for air traffic controllers and usually causes sleep deprivation, biological adaptations, and life changes for these workers. This study assessed quality of life, the sleep, and the health of 30 air traffic controllers employed at an international airport in Brazil. The objective was to identify health and quality of life concerns of these professionals. The results identified physical inactivity, overweight, excess body fat, low scores for physical and social relationships, and sleep deprivation for workers in all four workshifts. In conclusion, these workers are at risk for chronic non-transmittable diseases and compromised work performance, suggesting the need for more rest time before working nightshifts and work environments that stimulate physical activity and healthy diets.

Present mood states in Brazilian night nurses.

Variations in the state of momentary emotions of Brazilian hospital nurses on day and night shifts were recorded. Ten graduate nurses working on day and night shifts in the clinical ward of hospitals completed the Present Mood States List of Engelmann at the beginning and end of the first and last days of each shift. Analysis indicated (a) nurses had a stable emotional profile, present at the working shift, and (b) variations in present mood states related to specific effects of shift work were observed when comparisons were made between the present mood states at the beginning and end of each shift duty.

Este estudo objetivou investigar a percepção da qualidade de vida dos profissionais de enfermagem de terapia intensiva adulto e a sua relação com o tempo médio de sono e prática de atividade física. Realizou-se, para tanto, uma pesquisa transversal com 224 profissionais de enfermagem de seis unidades de terapia intensiva das regiões metropolitanas de Sorocaba e Campinas, no estado de São Paulo. A coleta de dados ocorreu entre agosto de 2015 e janeiro de 2016. Aplicou-se questionário para caracterização dos dados sociodemográficos, de sono e atividade física. A percepção de qualidade de vida foi avaliada por meio do instrumento WHOQOL-Bref. Para todas as análises foi considerado nível de significância igual a 5% e o software estatístico SAS versão 9.4 foi utilizado para a realização dessas análises. Prevaleceram os indivíduos do sexo feminino, casados, na função de técnicos de enfermagem, com média de idade de 36,12 (dp=8,26) anos. A maioria dos sujeitos dormia, em média, menos de seis horas por dia e não praticava atividade física, o que determinou a eles redução significativa das médias dos domínios da qualidade de vida. Concluiu-se que a privação de sono, a inatividade física e baixa renda mensal demonstraram, neste estudo, influenciar de maneira negativa a qualidade de vida de profissionais de enfermagem de terapia intensiva adulto.

This research aimed to investigate the perception of the quality of life of nursing professionals working in Adult Intensive Care Units and its relation with the average time of sleep and physical activity practice. A cross-sectional research was carried out with 224 nursing professionals from six intensive care units of the Metropolitan Regions of Sorocaba and Campinas, in São Paulo State. The data were collected between August 2015 and January 2016. A questionnaire was used to characterize the sociodemographic, sleep and physical activity data. The perception of quality of life was evaluated using the WHOQOL-Bref instrument. A significance level of 5% was considered for all the analyzes, and the statistical software SAS version 9.4 was used to perform them. There was a prevalence of married females in the role of nursing technicians, with a mean age of 36.12 (SD = 8.26) years old. The majority of the subjects slept on average less than six hours a day and did not practice physical activity, which caused them to significantly reduce the means of the domains on their quality of life. It was concluded that sleep deprivation, physical inactivity and lower monthly income showed, in this research, a negative influence on the quality of life of Adult Intensive Care Unit nursing professionals.

The relationship between shift work and sleep patterns in nurses.

The scope of this study was to evaluate the sleep/wake cycle in shift work nurses, as well as their sleep quality and chronotype. The sleep/wake cycle was evaluated by keeping a sleep diary for a total of 60 nurses with a mean age of 31.76 years. The Horne & Östberg Questionnaire (1976) for the chronotype and the Pittsburgh Sleep Quality Index (PSQI) for sleep quality were applied. The results revealed a predominance of indifferent chronotypes (65.0%), followed by moderately evening persons (18.3%), decidedly evening persons (8.3%), moderately morning persons (6.6%) and decidedly morning persons (1.8%). The sleep quality perception was analyzed by the visual analogical scale, showing a mean score of 5.85 points for nighttime sleep and 4.70 points for daytime sleep, which represented a statistically significant difference. The sleep/wake schedule was also statistically different when considering weekdays and weekends. The PSQI showed a mean of 7.0 points, characterizing poor sleep quality. The results showed poor sleep quality in shift work nurses, possibly due to the lack of sport and shift work habits.

Stress no cotidiano da equipe de enfermagem e sua correlação com o cronótipo / Stress resulting from the daily activities of the nursing team and correlation with chronotype

Este estudo teve como propósito classificar o cronótipo dos funcionários da equipe de enfermagem e identificar a presença de stress correlacionado ao cronótipo e turno de trabalho. Foi realizado em hospital privado da cidade de Limeira, estado de São Paulo, com 87 sujeitos, dos diferentes setores e turnos de trabalho. Os instrumentos utilizados foram o Inventário de Sintomas de Stress de Lipp e o Questionário de Indivíduos Matutinos e Vespertinos. Verificou-se que 74,7% dos sujeitos estavam adequados ao turno de trabalho; no entanto, 55,4% apresentavam sintomas de stress, demonstrando correlação estatisticamente significativa (Teste Exato de Fisher p=0,035). Verificou-se também stress nos sujeitos com maior tempo de serviço na instituição, comdiferença significativa (Teste Exato de Fisher p=0,003). Concluiu-se que a maioria dos sujeitos estava adequada ao turno de trabalho, de acordo com seu cronótipo, porém mesmo nestes indivíduos o stress foi observado, levando à confirmação de dados obtidos em outras pesquisas quanto ao caráter estressante da profissão.

The purpose of present study was to classify the chronotype of nursing staff, in order to identify the presence of stress and its correlation with chronotype and working hours. The study was conducted at a private hospital in the city of Limeira, in the state of São Paulo, with 87 subjects from different sectors and work shifts. The instruments used were: Lipp's Stress Symptom Inventory and a self-assessment questionnaire to determine morningness-eveningness in human circadian rhythms. We ascertained that 74.7% of the individuals were acclimated to shift working; however, 55.4% of them presented symptoms of stress - thereby demonstrating a significant statistical correlation (Fisherïs Exact Test, p=0.035). We also witnessed stress in subjects with a greater length of service in the institution, with a significant difference (Fisher's Exact Test, p=0.003). Most subjects were acclimated to their work shifts, in accordance with their personal chronotype, nevertheless even with these individuals stress could be observed, leading to the confirmation of data obtained in other research as to the stressful nature of the profession.
