Sleep duration and quality of Brazilian nursing staff who work in shifts.

OBJECTIVE: to analyze sleep duration and sleep quality in nursing professionals who work in shifts. METHOD: this is a cross-sectional, analytical research, carried out between September 2017 and April 2018, at a public hospital in southern Brazil, with the nursing team. A socio-occupational and health symptoms questionnaire, the Epworth Sleepiness Scale, and the Pittsburgh Sleep Quality Index were used. Data are presented as descriptive and inferential statistics, bivariate analysis, and binary logistic regression. RESULTS: participants were 308 nursing professionals with a predominance of long-term sleep, absence of drowsiness, and poor sleep quality. Short-term sleep (<6h) was associated with day shift and poor sleep quality. Sleep quality was associated with presence excessive daytime sleepiness and work day shift. CONCLUSION: work shift, insomnia and headache were the main factors related short-term sleep for nursing professionals. The results may justify the development of intervention research for workers' health.

Temporal patterns of food consumption and their association with cardiovascular risk in rotating shift workers.

OBJECTIVE: We aimed to evaluate the association of temporal patterns of food consumption with cardiovascular disease (CVD) risk. METHODS: This cross-sectional study included male rotating shift workers in an iron ore extraction company. Data on food consumption was collected using a 24 h recall, applied by trained interviewers. The variables for temporal patterns of food consumption were: eating window, eating at night, number of meals and omission of breakfast. CVD-risk was measured by calculating the Framingham coronary heart disease risk score (FCRS), and classified as low risk or intermediate to high risk. Descriptive, univariate and multivariate logistic regression analyses examined the association between variables related to temporal patterns of food consumption and CVD-risk. RESULTS: The study assessed 208 workers, the majority with 20-34 years (45.1%), non-white (77.2%), and 5 years or more in shift work (76.0%). Most participants had a feeding window exceeding 12 h (63.9%), consumed meals until 10 p.m. (68.1%), had five or more meals per day (54.8%), and did not skip breakfast (86.5%). Regarding CVD-risk, 43.8% of the participants were classified with intermediate to high risk for CVD. In the multivariate model, a feeding window (OR: 2.32; 95%CI: 1.01-5.35), eating after 10 p.m. (OR: 3.31; 95%CI: 1.01-11.0), and skipping breakfast (OR: 2.58; 95%CI: 1.07-6.19) increased the likelihood of intermediate to high CVD-risk. Conversely, having five or more meals per day decreased the odds (OR: 0.27; 95%CI: 0.08-0.92). CONCLUSION: Eating window longer than 12 h, eating after 10 p.m., less than four meals a day and omission of breakfast, are associated with cardiovascular risk in shift workers.

Estresse ocupacional entre psicólogos atuantes na atenção primária à saúde no contexto pandêmico / Occupational stress in psychologists working in primary health care in the context of the pandemic / Estrés laboral entre los psicólogos que trabajan en atención primaria de salud en el contexto de la pandemia

Este estudo analisa o estresse ocupacional entre psicólogos que atuavam na Atenção Primária à Saúde durante a pandemia ocasionada pela covid-19, assim como as características sociodemográficas e laborais dos participantes e sua relação com o estresse ocupacional. Participaram da pesquisa 70 psicólogos atuantes em 51 unidades básicas de saúde das regiões Oeste e Extremo Oeste catarinense. Para coleta de dados, um questionário sociodemográfico e a versão reduzida da Job Stress Scale (JSS) foram aplicados. A análise dos dados foi realizada por meio da estatística descritiva e inferencial. Identificou-se que 35,7% dos psicólogos apresentaram alto desgaste no trabalho; 28,6% baixo desgaste; 27,1% se mostraram em trabalho passivo; e 8,6% em trabalho ativo. No modelo de regressão linear, os fatores associados à dimensão Demanda da JSS foram: possuir filho (a) (coeficiente -1,49; IC 95% -2,75 a -0,23) e afastamento do trabalho nos últimos 12 meses (coeficiente 1,88; IC 95% 0,60 a 3,15). Os psicólogos com hipertensão arterial sistêmica autorreferida apresentaram, em média, 3,96 pontos a menos no escore de Apoio social (IC 95% -7,06 a -0,85), quando comparados aos não hipertensos, e entre os psicólogos que trabalhavam no turno da manhã identificou-se aumento de 4,46 pontos, em média, no escore de Apoio social (IC 95% 0,90 a 8,02) em relação aos profissionais do turno manhã e tarde. Evidenciou-se que um número significativo de psicólogos apresentava-se em alto desgaste no trabalho, com potenciais implicações para sua saúde e atuação profissional.(AU)

Sleep quality of nurses who worked in coping with COVID-19: an integrative review.

OBJECTIVE: to analyze sleep quality of nurses who worked coping with COVID-19 in scientific evidence. METHODS: an integrative review, carried out in seven databases, including studies between December 2021 and June 2022, without language restrictions. The sample consisted of 15 primary studies. RESULTS: nurses working in hospital, intensive care, outpatient care and teaching institutions constitute a vulnerable group for sleep disorders: latency, duration, efficiency and quality. The disorders identified involved insomnia at varying levels of severity: daytime dysfunction and morning sleepiness. Night work and low capacity for self-care were determinants of impaired sleep patterns. FINAL CONSIDERATIONS: the COVID-19 pandemic contributed to greater vulnerability of nurses to changes in sleep, requiring strategies for risk management and well-being promotion.

"Multivariate analysis of the impact of sleep and working hours on medical errors: a MICE approach".

BACKGROUND: The main objective of this study was to describe the relationship between working conditions, sleep and psycho-affective variables and medical errors. METHODS: This was an observational, analytical and cross-sectional study in which 661 medical residents answered questionnaires about working conditions, sleep and psycho-affective variables. Actigraphic sleep parameters and peripheral temperature circadian rhythm were measured in a subgroup of 38 subjects. Bivariate and multivariate predictors of medical errors were assessed. RESULTS: Medical residents reported working 66.2 ± 21.9 weekly hours. The longest continuous shift was of 28.4 ± 10.9 h. They reported sleeping 6.1 ± 1.6 h per day, with a sleep debt of 94 ± 129 min in workdays. A high percentage of them reported symptoms related to psycho-affective disorders. The longest continuous shift duration (OR = 1.03 [95% CI, 1.00-1.05], p = 0.01), working more than six monthly on-call shifts (OR = 1.87 [95% CI, 1.16-3.02], p = 0.01) and sleeping less than six hours per working day (OR = 1.66 [95% CI, 1.10-2.51], p = 0.02) were independently associated with self-reported medical errors. The report of medical errors was associated with an increase in the percentage of diurnal sleep (2.2% [95% CI, 0.1-4.3] vs 14.5% [95% CI, 5.9-23.0]; p = 0.01) in the actigraphic recording. CONCLUSIONS: Medical residents have a high working hour load that affect their sleep opportunities, circadian rhythms and psycho-affective health, which are also related to the report of medical errors. These results highlight the importance of implementing multidimensional strategies to improve medical trainees' sleep and wellbeing, increasing in turn their own and patients' safety.

Impact of Nighttime Food Consumption and Feasibility of Fasting during Night Work: A Narrative Review.

Shift work has been associated with an increased risk of developing chronic non-communicable diseases, such as obesity. The reduction in overnight fasting and its physiological consequences seem to affect the metabolic health of shift workers, but little has been discussed regarding the feasibility and implications of maintaining a night-long fast during work. This narrative review aims to discuss the impact of eating behavior on the reduction of overnight fasting in shift workers, as well as possible nutritional strategies involving fasting that have been tested for shift workers, to contribute to the establishment of nutritional guidelines for them. We used various databases and search engines to retrieve relevant articles, reviews, and investigations. Despite the potential benefits of overnight fasting for other groups, few studies have investigated this approach in the context of shift work. Generally, it seems to be a feasible and metabolically beneficial strategy for shift workers. However, it is essential to investigate the potential risks and benefits of reducing the fasting time for shift workers, considering social, hedonic, and stress-related factors. Furthermore, randomized clinical trials are necessary to establish safe and feasible strategies for shift workers to practice different fasting windows.

Sleep disorders and fatigue among truck and bus drivers in Mexico.

BACKGROUND: Fatigue and sleep disturbances are among the most common disorders suffered by transport drivers. OBJECTIVE: To identify and analyze working conditions for Mexican federal transportation truck and bus drivers, and their connection with sleep disorders and fatigue. METHODS: A cross-sectional, quantitative study was performed with a convenience sample of 172 drivers (84 truck and 88 bus) by applying the Survey Evaluation and Monitoring of Workers Health (PROESSAT in Spanish) and the Yoshitake Fatigue questionnaire. RESULTS: Night work and performing hazardous work increased the prevalence of sleep disorders (PR = 3.9 and PR = 6.9, respectively). Poor lighting and being paid per trip increased the prevalence of fatigue (PR = 2.8 and PR = 2.5, respectively). CONCLUSION: Several conditions were found to impact health, including long work shifts, strenuous physical effort, night work, little social support, being paid by distance, strict quality controls, and risk of crimes such as extortion, robbery, attacks, and kidnapping.

Shift Work and Early Arterial Stiffness: A Systematic Review.

Shift work is a way of organizing rotating schedules throughout the day. This can include 1-3 shifts for the same person on a rotational basis with other workers. Schedules that include night work have been associated with cardiovascular risk, mainly due to circadian misalignment. This systematic review sought to determine whether shift work is a risk factor for increased arterial stiffness. A systematic review of different databases was performed, using the following keywords: work shift, night work, arteriosclerosis, vascular stiffness, arterial stiffness, pulse wave velocity, and their Medical Subject Headings. We selected and analyzed 11 articles regarding pulse wave velocity as an indicator of arterial stiffness. Two studies identified higher levels of arterial stiffness in shift workers compared to day workers, while two studies found the opposite. In addition, four studies found no differences in arterial stiffness between shifts, two studies associated shorter sleep duration with arterial stiffness, and one study observed that physical activity could prevent adverse cardiovascular outcomes in shift workers. The findings are heterogeneous and preclude any robust conclusions. However, the present review points to the need for further studies to investigate arterial stiffness in shift workers, with greater control for confounding factors and longitudinal design.

The Effect of Exogenous Melatonin on Eating Habits of Female Night Workers with Excessive Weight.

BACKGROUND AND AIMS: Melatonin is a pineal hormone that plays an important role as an endogenous synchronizer of circadian rhythms and energy metabolism. As this circadian component has been closely related to eating behavior, an important question on this topic would be whether melatonin administration could influence eating habits. However, this topic has been rarely studied in the literature in individuals with excessive weight and chronic circadian misalignment, such as shift workers. Therefore, the present study aims to evaluate the effects of exogenous melatonin administration on the quali/quantitative aspects and temporal distribution of food intake in female night workers with excessive weight (overweight and obesity). An additional aim is to evaluate the association of the referred outcomes with circadian misalignment and chronotype. METHODS: A randomized, double-blind, placebo-controlled, crossover clinical trial was conducted with 27 female nursing professionals with excessive weight who worked permanent night shifts. The protocol was implemented under real-life conditions for 24 weeks, in two randomly allocated conditions (12 weeks of melatonin and 12 weeks of placebo). The quali/quantitative aspects of food intake (NOVA classification, total energy intake and the proportion of calories from macronutrients) and meal timing were assessed using food diaries. Timing for every meal recorded in the diaries was assessed to evaluate the temporal distribution of food intake. Generalized estimating equations were performed for each dependent variable. RESULTS: No significant modifications in total energy intake, macronutrient distribution, types of foods consumed, and meal timing were observed after melatonin administration. Different levels of circadian misalignment and chronotype did not interfere with these results. CONCLUSION: Eating habits of female night workers with excessive weight remained unchanged after melatonin administration, and no association of these results with circadian misalignment and chronotype was found. These results suggest that the metabolic effects of melatonin may occur independently of food intake.

Shift work schedule and damage to nursing workers' health at Brazilian public hospital.

OBJECTIVE: to compare work-related damage between the day and night shifts of nursing workers in at a public hospital. METHODS: a cross-sectional, and correlational study, conducted with 308 nursing workers from a Brazilian public hospital. Data collection took place from September 2017 to April 2018 using self-administered questionnaires that investigated socio-occupational variables and the effects of work (Work-Related Damage Assessment Scale). Analysis was descriptive and analytical with a 5% significance level. RESULTS: during the day shift, the variables that most influenced nursing professionals' health were body pain, headache, back pain, legs pain, and sleep disorders. When comparing the shifts, it was identified that daytime influences the studied variables more than nighttime. Job tenure was correlated with psychological damage. CONCLUSIONS: the results showed a greater influence of the day shift on the health of professionals who work in a hospital environment. Job tenure influences psychological damage.

Sleep quality, personal and work variables and life habits of hospital nurses. / Qualidade do sono, variáveis pessoais e laborais e hábitos de vida de enfermeiros hospitalares.

OBJECTIVE: to identify the possible associations between sleep quality, personal and work variables and the life habits of hospital nurses. METHOD: a cross-sectional, exploratory, correlational and quantitative study, carried out from October to December 2019. The data were collected with the application of a questionnaire that addressed the respondents' personal characteristics, life habits and working conditions. The Pittsburgh Sleep Quality Index (PSQI), Brazilian Portuguese version, was used to assess sleep quality. RESULTS: the participants were 42 professionals: 31 (73.8%) women, aged between 26 and 66 years old (mean of 40.2); 61.9% worked overtime; 26.2% had two employment contracts and 40.5% had absences from work. Sleep quality was considered good by 9.5% of the participants, poor by 64.3% and categorized as with sleep disorders by 26.2%. In the population that worked rotating shifts, this quality was identified as poor by 26.2%. The worst results were found in the age group from 30 to 39 years old and there was a statistical significance in the "living with a partner" variable. CONCLUSION: there was impairment in the nurses' sleep quality and there is a need to monitor these workers, particularly those who work in shifts, in order to provide preventive measures to mitigate the harms to their health.

Cardiovascular risk behavior among industrial workers in the Northeast of Brazil: a cluster analysis.

This research aimed to investigate the occurrence of clusters of cardiovascular risk behaviors and their association with social demographic and occupational characteristics in a population of industrial workers in the metropolitan area of Recife, Brazil. It was a transversal study with 727 workers of both genders. We identified cluster distribution from the variables: smoking, alcohol consumption, physical activity and waist circumference, by a combination of hierarchical and non-hierarchical analysis. We later tested the association with the social demographic and occupational variables with a multi-varied analysis. We have identified a protection cluster (sufficient physical activity, moderate alcohol consumption) and a risk cluster (high waist circumference, sedentarism, smoking, excessive alcohol consumption). The protection cluster was positively associated with night shift or variable shift work (RP: 1.66, IC95%: 1.26-2.17), and the risk cluster was associated with women (RP: 1.15, IC95%: 1.01-1.31). Cluster analysis allowed to identify that, for day shift workers and women, the shortest daytime outside the work environment can influence the adoption of cardiovascular risk behaviors.

Sleep analysis in emergency nurses' department.

BACKGROUND: Shift work increases the risk of suffering physiological and psychological alterations, due to the sleep disorders that it usually produces in the staff with this type of workday. OBJECTIVE: Analyze the influence of shift work on sleep quality in the nursing staff of the emergency department of the University Hospital of Leon. METHODS: A total of 70 emergency department nurses aged between 24-56 years were divided into two groups (rotating shift and fixed morning or afternoon shift). The Pittsburgh sleep quality index was used for this purpose. In order to establish differences between the two groups, a bivariate analysis was performed using the χ² test. RESULTS: The results showed that both groups had "rather poor" subjective sleep quality, with scores of 8.5 for fixed shift versus. 6.3 for a rotating shift. The group of nurses' rotating shifts slept an average of 5.39 hours compared to 7.47 hours for a fixed shift. Significant differences were found in sleep latency, sleep disturbances, and the use of sleep medication, with more negative results for the rotating shift. CONCLUSIONS: Rotating shift produces a poor quality of sleep compared to a fixed morning or afternoon shift, and it would be interesting for the center itself to establish sleep improvement and sleep hygiene programs.

Assessment of Attentional Functioning in Health Professionals of a Brazilian Tertiary Referral Hospital for COVID-19.

This study is aimed at assessing differences in basic attentional functioning between substantial and minimal work-related exposure to COVID-19 patients in professionals working in a tertiary referral hospital in Rio de Janeiro, Brazil. Therefore, hospital employees performed a Continuous Visual Attention Test. This test consisted of a 90-second Go/No-Go task with 72 (80%) targets and 18 (20%) nontargets. For each participant, reaction time and intraindividual variability of reaction times of all correct target responses, as well as the number of omission and commission errors, were evaluated. Participants were divided into 2 groups based on their exposure to COVID-19 patients (substantial versus minimal exposure). The substantial exposure group consisted of participants with 24 hours/week or more direct contact with COVID-19 patients. This cut-off was based on the clear division between professionals working and not working with COVID-19 patients and considered that 12-hour and 24-hour daily shifts are common for hospital employees in Brazil. A MANCOVA was performed to examine between-group differences, using age, sleep quality, sex, education level, previous COVID-19 infection, and profession as covariates. Of 124 participants, 80 had substantial exposure and 44 had minimal exposure to COVID-19. The overall MANCOVA reached statistical significance (P = 0.048). Post hoc ANCOVA analysis showed that the substantial exposure group had a statistically significantly higher intraindividual variability of reaction time of all correct target responses (P = 0.017, Cohen's δ = -0.55). This result remained after removing those with a previous COVID-19 infection (P = 0.010, Cohen's δ = -0.64) and after matching groups for sample size (P = 0.004, Cohen's δ = -0.81). No other variables reached statistical significance. Concluding, hospital professionals with a substantial level of exposure to patients with COVID-19 show a significant attention decrement and, thus, may be at a higher risk of accidental SARS-CoV-2 infection.

Association between chronotype and psychomotor performance of rotating shift workers.

It is known that the chronotype potentially mediates the performance and tolerance to work in shifts and that shift rotation is associated with negative effects on psychomotor performance. This study aimed to evaluate the effect of chronotype on psychomotor performance throughout a complete shift rotation schedule. Thirty males working in clockwise rotating shifts from a mining company were evaluated under a real-life condition over the following shift schedule: 2 days of day work, 2 days of evening work and 2 days of night work. The chronotype was determined using the Munich Chronotype Questionnaire adapted for shift workers and the obtained scores were categorized by tertiles (early-type, intermediate-type and late-type). Work performance was evaluated by Psychomotor Vigilance Test (PVT) daily just before shift starts and after shift ends. Sleep duration was evaluated by actigraphy over the whole shift. No isolated effect of the shift or interaction between shift and chronotype was found in the performance variables evaluated. A significant isolated effect of the chronotype showed that the early-type individuals had higher values of pre- and post-work Mean of Reaction Time (MRT) (308.77 ± 10.03 ms and 306.37 ± 8.53 ms, respectively) than the intermediate-type (257.61 ± 6.63 ms and 252.91 ± 5.97 ms, respectively, p < 0.001) and the late-type (273.35 ± 6.96 ms and 262.88 ± 6.05 ms, respectively, p < 0.001). In addition, late individuals presented a greater number of lapses of attention (5.00 ± 0.92; p < 0.05) than early (1.94 ± 0.50, p < 0.05) and intermediate (1.33 ± 0.30, p < 0.001) ones. We concluded that, compared with intermediates, late-type workers had a greater number of lapses of attention on the shift schedule as a whole, while early-type workers showed the highest pre- and post-work MRT. These findings show that the psychomotor performance of rotating shift workers seems to be influenced by the chronotype, but not by the shift rotation.

Sleep quality does not mediate the negative effects of chronodisruption on body composition and metabolic syndrome in healthcare workers in Ecuador.

BACKGROUND AND AIMS: The objective of the present work was to determine to what extent sleep quality may mediate the association between chronodisruption (CD) and metabolic syndrome (MS), and between CD and body composition (BC). METHODOLOGY: Cross-sectional study which included 300 adult health workers, 150 of whom were night shift workers and thereby exposed to CD. Diagnosis of MS was made based on Adult Treatment Panel III criteria. Sleep quality was measured using the Pittsburgh Sleep Quality Index. Body mass index (BMI), fat mass percentage, and visceral fat percentage were measured as indicators of body composition (BC). Data were analyzed using logistic, linear regression and structural equation models. RESULTS: The odds of health workers exposed to CD to suffer MS was 22.13 (IC95 8.68-66.07) when the model was adjusted for age, gender, physical activity and energy consumption. CD was also significantly associated with an increase in fat mass and visceral fat percentages, but not to BMI. Surprisingly, there was not enough evidence supporting the hypothesis that sleep quality contributes to the association between CD and MS or between CD and BC. CONCLUSIONS: Sleep quality does not mediate the negative effects of CD on MS nor on BC.

Eating Duration throughout a Rotating Shift Schedule: A Case Study.

OBJECTIVE: The impact of the rotation between different shifts and free days within a short period of time on the food consumption is poorly addressed in the literature. Our objective was to characterize the eating duration (ED) over 10 d of clockwise rotating and to associate it with the intake of energy and macronutrients. METHODS: Thirty male shift-workers from a mining company were evaluated over a complete rotation shift schedule of 10 consecutive days (2 d of morning shifts, 2 d of afternoon shifts, 24 h free-day, 2 d of night shifts, and three free days). ED was defined as the interval between the first meal after awaking and last meal before sleep onset. Sleep/wake periods and food intake were evaluated by actigraphy and 24 h recalls, respectively. Generalized models were used to analyze the variation in ED and its association with nutrient intake over the shift schedule. RESULTS: ED periods showed significant variations throughout shift rotation and were associated with energy intake. The highest energy intake (3410 ± 235 kcal) and longest ED (20.7 ± 1.2 h) were found on Day 5, the day between afternoon and night shifts, and a part of Day 6 (night shift), i.e., in the longest period of wakefulness and the shortest sleep duration (4.7 ± 0.3 h) (p < 0.05 for all). The lowest energy intake (1284 ± 125 kcal) and shortest ED (4.96 ± 0.7 h) (p < 0.05) occurred after the last night shift (Day 7). The balance between the percentage of macronutrients did not differ statistically between the ED periods. CONCLUSIONS: In general, longer periods of wakefulness showed greater energy intake, demonstrating the tendency of workers to eat around the clock during their shift. Even with the energy intake variation, the balance of macronutrients remained the same over the ED periods. Despite the need of confirmation in future studies, these results suggest that the management of ED period could be considered in the nutritional approach of shift workers.
