Abstract:

ObjectivesIn a 24/7 society, the negative metabolic effects of rotating night shift work have been increasingly explored. This study aimed to examine the association between rotating night shift work and non-alcoholic fatty liver disease (NAFLD) in steelworkers.MethodsA total of 6881 subjects was included in this study. Different exposure metrics of night shift work including current shift status, duration of night shifts (years), cumulative number of night shifts (nights), cumulative length of night shifts (hours), average frequency of night shifts (nights/month) and average length of night shifts (hours/night) were used to examine the relationship between night shift work and NAFLD.ResultsCurrent night shift workers had elevated odds of NAFLD (OR, 1.23, 95% CI 1.02 to 1.48) compared with those who never worked night shifts after adjustment for potential confounders. Duration of night shifts, cumulative number of night shifts and cumulative length of night shifts were positively associated with NAFLD. Both the average frequency of night shifts (>7 nights/month vs ≤7 nights/month: OR, 1.24, 95% CI 1.06 to 1.45) and average length of night shifts (>8 hours/night vs ≤8 hours/night: OR, 1.27, 95% CI 1.08 to 1.51) were independently associated with overall NAFLD after mutually adjusting for the duration of night shifts and other potential confounders among night shift workers. No significant association was found in female workers between different exposure metrics of night shift work and NAFLD.ConclusionsRotating night shift work is associated with elevated odds of NAFLD in male steelworkers.

ObjectiveTo examine the associations of rotating night shift work with hyperhomocysteinaemia (HHcy) odds by different exposure metrics.DesignCross-sectional study.SettingOccupational physical examination centre for steel production workers, Tangshan, China.ParticipantsA total of 6846 steelworkers, aged 22–60 years, from the baseline survey of a Chinese occupational cohort.Primary and secondary outcome measuresDifferent exposure metrics of night shift work, including current shift status, duration of night shifts (years), cumulative number of night shifts (nights), cumulative length of night shifts (hours), average frequency of night shifts (nights/month), average length of night shifts (hours/night) and percentage of hours on night shifts, were used to examine the effects of past and current night shift work on HHcy odds. The total homocysteine concentration in the plasma above 15 µmol/L was defined as HHcy.ResultsCompared with those who never worked night shifts, current night shift workers had elevated odds of HHcy (OR 1.23, 95% CI 1.06 to 1.44). Considering a person’s lifetime work schedule and compared with individuals who never worked night shifts, duration of night shifts >28 years (OR 1.35, 95% CI 1.12 to 1.61), average frequency of night shifts >7 nights/month (OR 1.25, 95% CI 1.07 to 1.47) and percentage of hours on night shifts >30% (OR 1.23, 95% CI 1.05 to 1.43) were associated with higher HHcy odds. The duration of night shifts >20 years and the average frequency of night shifts >7 nights/month could significantly increase the odds of HHcy regardless of whether the average length of night shifts was greater than 8 hours/night. After stratification by sex, no significant association was found in female workers between different exposure metrics of night shift work and HHcy.ConclusionsLong duration and high frequency of night shift work are associated with higher HHcy odds among male steelworkers.

Abstract:

Demands of modern society force many work operations into the night when the internal circadian timekeeping system is promoting sleep. The combination of disturbed daytime sleep and circadian misalignment, which is common in overnight shift work, decreases cognitive performance, yet how performance may differ across multiple consecutive nights of shift work is not fully understood. Therefore, the primary aim of this study was to use a simulated night-shift protocol to examine the cognitive performance and ratings of sleepiness and clear-headedness across the hours of a typical daytime shift, a first night shift with an afternoon nap and extended wakefulness, and 2 subsequent overnight shifts. We tested the hypothesis that cognitive performance would be worse on the first night shift as compared with the baseline and subsequent nighttime shifts and that performance during nighttime shifts would be reduced as compared with the baseline daytime shift. Fifteen healthy adults (6 men) were studied in the 6-day in-laboratory protocol. Results showed that working during the night increased subjective sleepiness and decreased clear-headedness and performance on the Psychomotor Vigilance Task (i.e., slower median, fastest and slowest reaction times, and increased attentional lapses), Stroop color word task (decreased number of correct responses and slower median reaction time), and calculation addition performance task (decreased number attempted and correct). Furthermore, we observed limited evidence of sleepiness, clear-headedness, or performance adaptation across subsequent nights of simulated night work. Our findings demonstrate that night-shift work, regardless of whether it is the first night shift with a nap and extended wakefulness or subsequent night shifts, decreases performance and clear-headedness as compared with the day shift.

Abstract:

Working at day (morning and afternoon shift) is normal working times according to human physiological conditions, but working at night would impact to the sleep cycle and regulation of human homeostasis. Various studies have found that working at night causing conditions that can interfere the ability to adapt both biologically and socially. Workers on the night shift also have a higher risk of injury or accidents due to work fatigue. This stydy aims to determine the fatigue score between night and non-noght shift workers at Dr Harjono S Hospital, Ponorogo. Data Collected in August 2019 and involved 80 medical workers as respondents who were randomly selected using simple random sampling technique. Data were obtained through direct observation and interviews to respondents. Fatigue was measured in numerical score with Fatigue Assesment Scale (FAS) Instrument. Work shift variables (WS) are divided into : non-night shift (morning, noon) and night shift (morning, noon, night). To find out the differences in physical conditions of workers in each shift, the Heart Rate (HR) of the night shift workers measured in the end of three shifts (morning : 07-14.00; Afternoon : 14.00-21.00; and night :21.00-07.00). Using independent T-test analysis, there was a significant difference in Fatigue Level of workers with night shifts and non-night shifts (p < 0.000). Workers with the night shift has 29.0 of Fatigue Levels or 21 % greather than workers with non-nigh shift (Fatigue Level : 24.2). Result shows that working at night increasing level of fatigue by 21 % than working at day. Workers on the night shift have the highest HR at the end of the shift (86.311 bpm) while workers at noon shift have the lowest HR (85.2). Keywords: Occupational fatigue, work shift, medical workers

Abstract:

To better understand Shift Work Disorder (SWD), this study investigates insomnia, sleepiness, and psychosocial features of night workers. The study compares night workers with or without SWD to day workers with or without insomnia. Seventy-nine night workers and 40 day workers underwent diagnostic interviews for sleep disorders and for psychopathologies. They completed questionnaires and a sleep diary for 14 days. The design was observatory upon two factors: Work schedule (night, day work) and sleep (good sleep, SWD/insomnia). Two-way ANCOVAs were conducted on psychosocial variables, and effect size were calculated. The clinical approach chosen led to distinct groups of workers. Night workers slept several periods (main sleep period after work, naps, nights on days off). High total wake time and low total sleep time characterized sleep in SWD. Most night workers with SWD still complained of sleepiness after main sleep. Cognitive activation distinguished groups of night workers. All other differences in psychosocial variables between night workers groups were similar to, but smaller than, the ones between day workers. The evaluation of SWD should consider all sleep periods of night workers with particular attention to self-reported total wake time, state sleepiness, and level of cognitive activation.

Abstract:

The aim of this study was to evaluate the associations of rotating night shift work with body fat percentage (BF%) and fat mass index (FMI). A cross-sectional study was conducted among 435 female steelworkers, aged 26–57 years in Tangshan, China. BF% was assessed via bioelectrical impedance analysis and FMI was calculated. Different exposure metrics of night shift work were used to examine the effects of night shift work on BF% and FMI. The duration (years), cumulative number (nights), and cumulative length of night shifts (hours) were positively correlated with FMI and BF%, and these relationships were independent of body mass index (BMI). Compared with day workers, night shift workers with an average frequency of night shifts >7 nights/month (odds ratio (OR) 2.50, 95% confidence interval (CI) 1.17 to 5.35) and percentage of hours on night shifts >30% (OR 2.55, 95% CI 1.21 to 5.39) had elevated odds of obesity (BF% ≥ 35.0%). Nonobese night shift workers by the BMI criterion should also be alert to the risk of the excess accumulation of body fat, which is actually responsible for most obesity-associated adverse health consequences. Health interventions for related populations need to be improved, which is currently more focused on overall weight control.

Abstract:

Abstract Night-shift work involving disruption of circadian rhythms has been associated with breast cancer risk. A role in prostate cancer is also suspected, but evidence is limited. We investigated the association between night-shift work and prostate cancer incidence in the Prostate Cancer and Environment Study (PROtEuS), a population-based case-control study conducted in 2005–2012 in Montreal, Quebec, Canada. Participants were 1,904 prostate cancer cases (432 high-grade cancers) and 1,965 population controls. Detailed work schedules for each job held for at least 2 years (n = 15,724) were elicited in face-to-face interviews. Night-shift work was defined as having ever worked ≥3 hours between midnight and 5:00 am ≥3 nights/month for ≥1 year. Unconditional logistic regression was used to estimate odds ratios and 95% confidence intervals for the association between night-shift work and prostate cancer, adjusting for age, ancestry, and education. No association was found between overall prostate cancer and night-shift work metrics, including ever exposure, duration, intensity, cumulative exposure, rotating shifts, and early-morning shifts. For none of the exposure indices was there evidence of heterogeneity in odds ratios between low- and high-grade cancers. Sensitivity analyses restricting exposures to ≥7 nights/month or considering screening history yielded similar results. Our findings lend no support for a major role of night-shift work in prostate cancer development.

Abstract:

The research problem is the increasing numbers of overweight and obese nurses working the night shift. Study on overweight and obesity among female Filipino nurses has not been conducted. It was important to conduct a research study among female Filipino nurses to find out if there are statistically significant associations between night shift work and weight gain. The purpose of this correlational and cross-sectional study was to determine if there are statistically significant associations between insufficient sleep, abnormal eating patterns, working 12-hour shifts, years of working night shift, age, stress, marital status, nursing units, decreased physical activity, and level of weight gain among female Filipino nurses working the night shift in the hospital. The theoretical base of this study was the locate evidence, evaluate evidence, assess evidence, and informed decision model. The survey questionnaire was constructed and an online survey through Survey Monkey was used to access nurses via a convenience sampling. Data were analyzed using Spearman correlation, multiple regression, and ANOVA. According to study findings, there were significant associations between insufficient sleep, abnormal eating patterns, marital status, 12-hour shifts, number of years working on night shift, and increased in body mass index. The implications for social change include information that nurses can use to better understand the negative implications of night shift work on health. At the organizational level, this study provides information for administrators and nursing leaders that might facilitate change in policies by improving working conditions for nurses.

Abstract:

Nurses are largely unaware of the problems of night-shift-nurse sleepiness and available strategies to manage night-shift sleepiness. The purpose of this project was to examine nurses' self-perception, awareness of sleepiness, and current strategies to manage this problem in the emergency medicine department of a major academic hospital in the western United States. The validated de-identified Karolinska Sleepiness Scale (KSS) was used to measure the prevalence and intensity of night shift nurses' sleepiness prior to the development of an educational program on strategies to manage sleepiness. Of the 164 registered nurses surveyed, 72 (43.9%) reported sleepiness greater than 7 on the KSS. An educational program was developed and evaluated by a panel of 6 experts who were selected on their clinical, educational, quality improvement, and research in sleep studies. Expert reviews indicated that the education program was 100% relevant, appropriate, and understandable, and provided adequate information on the topic with no recommended changes. The education program was presented to 16 night shift nurses with a pre/posttest survey completed by 14 nurses. Results indicated that participating nurses increased their knowledge of managing strategies for sleepiness from 69% (agree or strongly agree) preintervention to 92% postintervention. Postintervention, there was a 50% increase in the number of nurses who reported benefits from the education intervention. The findings of this project contribute to positive social change by improving nurses' health and quality patient care by advancing nurses' awareness of night shift sleepiness and countermeasure management strategies.

Abstract:

This study investigated the effects of night work on performance efficiency. Night work is generally acknowledged to impair performance, yet much research has contradicted this assertion. The feasibility of including brief periods of physical activity to stimulate arousal within mentally demanding work shifts was also evaluated. Thirty six postgraduate volunteers were assigned to either the cognitive tasks (CT) or cognitive and motor tasks (CMT) group. All subjects performed three psycho-motor tests, using the Vienna Test System, at midday and midnight. The CMT group performed a short cycling activity before each test. Heart rate responses served as physiological measures, the Perceived Strain Scale was used to quantify individual perceptions of strain and performance efficiency was assessed in terms of speed and accuracy. Although several trends were apparent, no significant differences (p < 0.05) were revealed with respect to the three performance variables between the midday and midnight test sessions, or between the CT and CMT subjects, other than the higher heart rates recorded in the CMT group. In summary, neither time of day nor physical activity were found to affect performance within the controlled environment of this study.

Abstract:

The night shift environment in acute care nursing is a unique and poorly understood entity. Retention of experienced nurses on the night shift is vital to the provision of quality care and the nurturing of new nurses. The goal of this phenomenological study was to elicit a description of the lived experience of experienced night shift nurses with the goal of gleaning information that would improve the work environment on the night shift. Five experienced night shift RNs participated in self-directed interviews, responding to the question, "Can you please share your experiences as an RN working the night shift?" The interview data were analyzed using Giorgi's phenomenological method to arrive at a typical and essential structure of the experience. The results revealed negative and positive aspects of working a night shift schedule. Negative aspects of night shift nursing included a feeling of being misunderstood and undervalued professionally and personally. Inadequate resources, on the night shift, was also identified as a barrier to nurse satisfaction, and negatively influencing the provision of quality nursing care and quality orientation of new nurses. Negative physiologic influences of night shift centered around poor quality and quantity of sleep. While these negative influences were consistently presented by all participants, so were the positive aspects of night shift nursing. The participants of this study were strongly invested in the teamwork they experienced within their night shift work environment. Interdependent team spirit was found to have arisen in response to the lack of resources experienced by these nurses. This teamwork, along with the other positive aspects, such as autonomous practice and positive effects on personal time, were seen as incentives for these experienced nurses to continue nursing on the night shift. Nursing administration may be able to utilize the information gleaned from this study to optimize the night shift work environment, and subsequently, increase retention of the experienced nurse. Further research is needed to clarify: the needs of experienced nurses in varying clinical settings, the needs of inexperienced night shift nurses, and the representativeness of the data found in this study to larger numbers of nurses.

Abstract:

Approximately 3.6 million individuals in the UK are involved in a type of shift-work which impinges on the normal nocturnal sleeping period. This prevalence has significance considering that shift-work is a risk factor for many health problems including cardiovascular disease, breast cancer, metabolic syndrome, obesity and gastrointestinal symptoms (e.g., constipation). These health inequalities are generally under-researched. Past studies have also focused on chrono-biological related reasons (e.g., exposure to light at night) rather than lifestyle factors. Physical activity is reported to be beneficial for many aspects of day-worker's health. However, there is a dearth of knowledge regarding the relationship between physical activity, adiposity and gastrointestinal symptoms in shift-workers. Thus, the aim of this thesis was to explore, using a multidisciplinary approach, the relationships between body mass index (8M I), appetite regulation, gastrointestinal health and physical activity during shift-work and night-work. In the first study (presented in Chapter 3), a cross-sectional study design was adopted to explore the relationships between 8MI, gastrointestinal symptoms and leisure-time physical activity (LTPA) in shift-workers. The data from this study indicated that the least active shift-workers had the highest mean 8MI, 73% of these workers being overweight or obese. Nevertheless, dose-response effects of LTPA on 8MI were not evident. A positive relationship was present between physical activity level and frequency of heartburn but not other digestive symptoms (e.g., diarrhoea). In the studies presented in Chapters 4 and 5, the effects of an acute bout of evening exercise upon appetite-related factors were investigated during a simulated night-shift. In Chapter 4, the protocol was characterised by a feeding schedule typically adopted by many shift-workers, Le. eating smaller but more frequent portions of food rather than one large meal. In contrast, the protocol in Chapter 5 was characterised by a feeding schedule designed to be more in line with what day-workers do during their work-period, i.e. eating one larger meal 3-4 h after the work period has started. Findings from Chapter 4 indicate that, unlike after diurnal exercise, circulating concentrations of acylated ghrelin and leptin during a night-shift are increased by prior evening exercise. However, hunger during the night-shift was unaffected by prior evening exercise in this study. In the subsequent experiment involving one large meal, nocturnal concentration of serum leptin was increased by exercise but there was little effect on plasma acylated ghrelin level. Again, night-shift hunger was unaffected by prior evening exercise. Taken together, these findings indicated that exercise mediates different effects on appetite-related hormones at night and that meal frequency is an important factor which regulates the response of acylated ghrelin, but not leptin. Despite the above findings, mean night-shift hunger was unaffected by evening exercise, regardless of meal frequency. This implies that a compensatory increase in food intake during the night-shift in response to prior exercise may not occur, thus supporting the notion that exercise can mediate a negative energy balance which might attenuate body mass gain in shift-workers. The study presented in Chapter 6 determined the within-subject correlations between factors that regulate appetite in the post-exercise period. This study explored how circulating levels of acylated ghrelin and leptin are controlled at night following evening exercise. The findings from Chapter 6 suggested that exercise related changes in plasma acylated ghrelin concentration are negatively correlated to those in circulating levels of glucose and insulin, but not those in non-esterified fatty acids (NEFA) or triglyceride. The aforementioned Significant correlations were not reported in daytime studies. Post-exercise alterations in serum leptin level were also found to be related to those in circulating levels of insulin but not those in glucose, NEFA or triglyceride. The exercise-related alterations in circulating level of acylated ghrelin, but not leptin were correlated with the changes in hunger during the post-exercise period throughout the night. In the study presented in Chapter 7, a randomised controlled trial was employed to examine the effect of altering (via motivational interviewing over a three month period) a shift-worker's physical activity and dietary habits on their adiposity and gastrointestinal symptoms. The findings presented in Chapter 7 indicate that a 12-week motivational interviewing intervention which focused upon increasing physical activity level and improving dietary habits significantly attenuated an increase in 8MI, but not waist-to-hip ratio or frequency of digestive symptoms in UK shift-workers. In summary, this thesis makes a significant contribution to the field of physical activity and shift-work. This thesis demonstrates that relationships between 8MI, appetite regulation, gastrointestinal health (l.e., heartburn) and physical activity do exist during shift-work and night-work.

Abstract:

The primary consequence of night shift work is a misalignment of the endogenous circadian pacemaker with the inverted sleep-wake cycle. This study evaluated the efficacy of a judicious schedule of light exposure on circadian adaptation to night work. Fifteen night shift workers (mean age +/-S.E.M.: 41.8 +/- 1.8 years) were studied for 3 weeks in their work environments under one of two experimental conditions. Treatment group participants underwent an intervention including bright light in the workplace, while control group participants were studied in their habitual light environments. The efficacy of the intervention was evaluated in the laboratory via constant routines. Following the intervention, treatment group subjects displayed a mean phase delay of (+/-S.E.M.) -9.32 +/- 1.06 hours and full entrainment to the night-oriented schedule while control group subjects displayed a phase delay -4.09 +/- 1.94 hours and a partial entrainment (F(1,30) = 11.33, p = 0.002). The results of this study suggest a means of alleviating the difficulties associated with night shift work with control of the overall pattern of light exposure.

Abstract:

Background Night shift work is inevitable for maintaining continuous services in different sectors e.g. healthcare, financial, transport and service sectors. Night shift work increases exposure of light at night. Exposure of light at night suppresses production of a neurohormone melatonin. Melatonin has shown potential cancer protective action in animal experiments. Melatonin deficiency is suggested to be related to the development of various cancer especially breast cancer. Breast cancer incidence in Hong Kong is rising. Particular concern about association between night shift work and breast cancer is raised. Objective To collect evidence from studies of other countries with study populations of different professions and to evaluate the relationship between night shift work and breast cancer Method MEDLINE was searched to identify publications, limited to English articles, from 1973 to May 2011. Search terms include (circadian rhythm or night work or night shift or shift work or work schedule tolerance) and (cancer or neoplasm or neoplasia) and (risk or rate or incidence). No restriction was set to the publication type. Results Altogether 343 titles retrieved from MEDLINE search. Finally, 8 primary observational studies that met inclusion criteria were identified for this review. Of these, two were prospective cohort studies, one was retrospective cohort study, two were nested case-control studies and three were case-control studies. Most of the study had crude exposure assessment of night shift work, in which four studies relied on group level of exposure probability instead of individual exposure information. Six of eight studies showed positive results on the association of night shift work and breast cancer in women. Three studies found that risk of breast cancer was increased significantly for those who had engaged in night shift work in a long duration i.e. more than 20-30 years, but they were all conducted in populations of same occupational group i.e. nurse and only a moderate increase of breast cancer risk was found. The results were subject to confounding and bias. No consistent results were found for effect of shorter duration of night shift work on risk of breast cancer. Conclusion Based on the studies included, there is suggestive evidence of an association of night shift work and breast cancer. Further studies on this are needed. Involvement of population of different occupational groups, controlling confounder of hormone use and conducting exposure assessment with high reliability using individual information instead of that from group are suggested.

Abstract:

AbstractIn healthcare companies, shiftwork organization is fundamental to ensure continuous 24-h patient care. This chapter gives an overview of health-related problems associated with shift work and the preventative actions that can be taken to protect workers’ health and well-being. Shift work, in particular night work, results in a disruption of biological circadian rhythms with serious social and psychophysical ramifications for the worker. The adverse health effects of shift work can be both in the short-term (sleep, digestive, mental, and menstrual disorders) and in the medium- to long-term (increased gastrointestinal, neuropsychic, metabolic, and cardiovascular diseases). In 2007, the IARC classified shift work as “probable carcinogen” for humans due to the destructive effects on the circadian rhythm. The modification of the sleep/wake cycle also negatively influences worker’s vigilance and performance (“jet-lag syndrome”) leading to a consequently greater risk of accidents and errors. Shift work can be harmful to the safety of both the worker and the patient. Appropriate shift scheduling that respects ergonomic criteria is important to protect worker and patient health and well-being. Medical residents should be conscious of the legislation and rights regarding shift work to ensure they provide appropriate assistance to patients and to preserve their own social and psychophysical well-being.

Full text

Abstract:

With a few exceptions, research on ride-hailing has focused on North American cities. Previous studies have identified the characteristics and preferences of ride-hailing adopters in a handful of cities. However, given their marked geographical focus, the relevance and applicability of such work to the practice of transport planning and regulation in cities in the Global South is minimal. In developing cities, the entrance of new transport services follows very different trajectories to those in North America and Europe, facing additional social, economic, and cultural challenges, and involving different strategies. Moreover, the determinants of mode choice might be mediated by social issues such as the perception of crime and the risk of sexual harassment in public transportation, which is often experienced by women in large cities such as Mexico. This paper examines ride-hailing in the Metropolitan Area of Mexico City, unpacking the characteristics of its users, the ways they differ from users of other transport modes, and the implications for urban mobility. Building on the household travel survey from 2017, our analytical approach is based on a set of categorical models. Findings suggest that gender, age, education, and being more mobile are determinants of ride-hailing adoption. The analysis shows that ride-hailing is used for occasional trips, and it is usually done for leisure and health trips as well as for night trips. The study also reflects on ride-hailings implications for the way women access the city.

Abstract:

Nonprofit organizations are responsible for providing a significant level of human services across the United States, often in collaboration with government agencies. In this work, they address some of the most pressing social issues in society – including homelessness, poverty, health care and education. While many of these organizations consider location and accessibility crucial to supporting their clients – often locating services near bus or train stops, for example – little is known about the impact of new technologies, including ride hail services like Lyft and Uber, on nonprofit accessibility. These technologies, which are re-shaping transportation in both urban and suburban communities, are expected to dramatically shift how people move around and the accessibility of services they seek. This exploratory qualitative study, making use of interviews with nonprofit executives and nonprofit clients, is among the first of its kind to measure the impact of ride hail services and other emerging technologies on community mobility and accessibility.

Abstract:

This report describes the experiences of over 600 undergraduates who were taking STEM courses with in-person class meetings that had to shift to remote instruction in spring 2020 because of COVID-19. Internet connectivity issues were serious enough to interfere with students’ ability to attend or participate in their STEM course at least occasionally for 46% of students, with 15% of students experiencing such problems often or very often. A large majority of survey respondents reported some difficulty with staying motivated to work on their STEM courses after they moved online, with 45% characterizing motivation as a major problem. A majority of STEM students also reported having problems knowing where to get help with the course content after it went online, finding a quiet place to work on the course, and fitting the course in with other family or home responsibilities. Overall, students who reported experiencing a greater number of major challenges with continuing their course after it went online expressed lower levels of satisfaction with their course after COVID-19. An exception to this general pattern, though, was found for students from minoritized race/ethnicity groups, females, and lower-income students. Despite experiencing more challenges than other students did with respect to continuing their STEM courses remotely, these students were more likely to rate the quality of their experiences when their STEM course was online as just as good as, or even better than, when the course was meeting in person.
