Objectives: This study examined the effect of shift work on developing the metabolic syndrome by comparing groups of exposed and unexposed Iranian drivers. Methods: We considered as night-shift drivers those drivers whose shifts included at least 15 h per week between 9:00 p.m. and 7:00 a.m. Daytime drivers were defi ned as drivers working regularly without shift work. 3039 shift work drivers were selected. These were matched with non-shift workers. The differences in baseline characteristics and the prevalence of the components of the metabolic syndrome were assessed with Student's t test, and chi-square tests. Results: We found central adiposity in 52.0% of the shift workers versus 42.6% of the day workers (p < 0.0001). The hypertension component was not signifi cantly related to shift work (p > 0.05); but there were signifi cant differences as regards other components of the metabolic syndrome (p < 0.0001). Among the shift workers, the odds ratios of the increased FBS, low HDL-C, higher TG levels, as well as higher waist circumference were 1.992 (95% CI: 1.697-2.337), 1.973 (95% CI: 1.759-2.213), 1.692 (95% CI: 1.527-1.874), and 1.460 (95% CI: 1.320-1.616), respectively. The metabolic syndrome was more common among the shift workers (OR = 1.495; 95% CI: 1.349-1.657). Conclusion: In evaluating such results, further consideration is needed to fi nd pathophysiological clarifi cation; in turn, stress linked to shift work must be considered to likely have had a relevant infl uence on the outcome. In our opinion, shift work acts as an occupational factor for the metabolic syndrome.

Nurses are often obliged to work in a 12-hr shift work system. We have decided to check whether such a working system constitutes an excessive load for nurses. On the basis of a questionnaire survey among nurses working in an 8-hr daytime shift system (169 nurses) and in a 12-hr shift (536 nurses), the amount of physical workload, work stress, and after-work activities were compared. Data analysis has shown that a 12-hr shift system is characterized by less significant physical workload but greater mental load. The nurses working in a 2-shift system were more tired after work, but they could spend more time on leisure activities and do housework. The data suggest that there are no significant contraindications for nurses to work in a 2-shift system.

Objectives Existing research has documented that shiftwork consequences may depend on the shift system parameters. Fast rotating systems (1–3 shifts of the same kind in a row) and day work have been found to be less disruptive biologically and socially than slower rotating systems and afternoon and night work. The aim of this study was to compare day workers and shift workers of different systems in terms of rotation speed and shifts worked with regard to work–family and family–work positive and negative spillover, marital communication style, job satisfaction and health. Material and Methods Employees (N = 168) of the maintenance workshops of transportation service working different shift systems (day shift, weekly rotating 2 and 3‑shift system, and fast rotating 3-shift system) participated in the study. They completed the Work– Family Spillover Questionnaire, Marital Communication Questionnaire, Minnesota Job Satisfaction Questionnaire and the Physical Health Questionnaire (a part of the Standard Shiftwork Index). Results The workers of quicker rotating 3-shift systems reported significantly higher scores of family-to-work facilitation (F(3, 165) = 4.175, p = 0.007) and a higher level of constructive style of marital communication (Engagement F(3, 165) = 2.761, p = 0.044) than the workers of slower rotating 2-shift systems. There were no differences between the groups of workers with regard to health and job satisfaction. Conclusions A higher level of work–family facilitation and a more constructive style of marital communication were found among the workers of faster rotating 3-shift system when compared to the workers of a slower rotating 2-shift system (afternoon, night). This may indicate that the fast rotating shift system in contrary to the slower rotating one is more friendly for the work and family domains and for the relationship between them.

Objectives The aim of this study was to explore the relationship between socio-demographic characteristics and the level of complementary and supplementary person–organization fit (P–O fit). Material and Methods The study sample was a group of 600 Polish workers, urban residents aged 19–65. Level of P–O fit was measured using the Subjective Person–Organization Fit Questionnaire by Czarnota-Bojarska. The binomial multivariate logistic regression was applied. The analyzes were performed separately for the men and women. Results Socio-demographic variables explained small percentage of the outcome variability. Gender differences were found. In the case of men shift work decreased complementary and supplementary fit, while long working hours decreased complementary fit. In the women, age was a stimulant of a complementary fit, involuntary job losses predicted both complementary and supplementary misfit. Additionally, relational responsibilities increased probability of supplementary P–O fit in the men. Conclusions Going beyond personality and competences as the factors affecting P–O fit will allow development of a more accurate prediction of P–O fit.

ObjectivesThis study aimed to investigate the prevalence of insomnia and risk factors among different job categories of steel workers in China, in order to improve their quality of occupational life.Material and MethodsA cross-sectional face-to-face survey was conducted which involved 5834 steel workers from a large enterprise located in northern China, including front-line, maintenance and inspection, and other auxiliary workers. The Athens Insomnia Scale and the Job Content Questionnaire were used to assess the status of insomnia and job stress/social support, respectively. Multivariable logistic regression was used to identify factors influencing insomnia.ResultsThe overall prevalence of insomnia was determined at 42.0% (95% confidence interval: 40.7%–43.2%). For front-line, maintenance and inspection, and other auxiliary workers, the prevalence was 42.3%, 39.8%, and 47.9% (p = 0.001), respectively. The participants with high stress and low support, and those who had experienced ≥2 major life events in the past 12 months, compared to those with low stress and high support, and those without major events, displayed an increased risk of insomnia among all 3 job categories (the adjusted odds ratio ranged 1.56–2.38 and 1.30–1.75, respectively). The educational level, shift work, alcohol consumption, and present illness were identified as influencing factors of insomnia for 1 or 2 job categories.ConclusionsThe prevalence of insomnia was the highest in the group of other auxiliary steel workers among the 3 job categories of steel workers under consideration. While the influencing factors of insomnia differed among the groups, job stress and major life events were common risk factors of insomnia among the 3 categories of steel workers.

ObjectivesEpidemiological observations indicate that female flight attendants are exposed to some reproductive and endocrine system disturbances. The aim of the study was to determine the incidence of hyperprolactinemia among female flight attendants, and to identify factors affecting the secretion of prolactin in female flight attendants working within 1 time zone as well as on long-distance flights.Material and MethodsThe cross-sectional study covered 103 women aged 23–46 years. The study group (I) was divided into 2 subgroups: subgroup Ia comprising female flight attendants flying within 1 flight zone, and subgroup Ib composed of female flight attendants working on long-distance flights. The control group (II) included women of reproductive age who sought medical assistance due to marital infertility in whom the male factor was found to be responsible for problems with conception in the course of the diagnostic process. The assessment included: age, the body mass index, menstrual cycle regularity, the length of service, the frequency of flying, the prolactin, estradiol and progesterone concentrations, and the result of endometrial biopsy. Descriptive and inferential statistics methods were used to compile the data.ResultsThe incidence of hyperprolactinemia in the female flight attendants (46%) was significantly higher than in the control group (9%), p < 0.001. Differences between subgroups Ia and Ib regarding individual concentrations were not statistically significant (p = 0.425). Hyperprolactinemia among the female flight attendants working ≥15 years is present slightly more often than in those working <15 years: 46% vs. 45% (p > 0.05). No significant difference was revealed in the secretion of prolactin between the study participants spending <60 h/month flying and those spending ≥60 h/month flying (p > 0.05).ConclusionsHyperprolactinemia is more common in female flight attendants than in the general population. High values of prolactin concentration in flight attendants are rarely manifested in clinical symptoms. The frequency of flying and the length of service do not affect the development of hyperprolactinemia or the mean prolactin concentration.

Objectives: Workers in the mining industry in altitude are subjected to several risk factors, e.g., airborne silica and low barometric pressure. The aim of this study has been to assess the risks for this work category, evaluating single risk factors as airborne silica, altitude and work shift, and relating them with cardiovascular and ventilatory parameters. Material and Methods: Healthy miners employed in a mining company, Chile, working at varied altitudes, and subjected to unusual work shifts, were evaluated. Cardiovascular and respiratory parameters were investigated. Exposure to airborne silica was evaluated and compared to currently binding exposure limits. Results: At varied altitudes and work shifts, alterations emerged in haemoglobin, ventilation and respiratory parameters, related to employment duration, due to compensatory mechanisms for hypoxia. Haemoglobin increased with altitude, saturation fell down under 90% in the highest mines. The multiple linear regression analysis showed a direct relationship, in the higher mine, between years of exposure to altitude and increased forced vital capacity percent (FVC%), and forced expiratory volume in 1 s (FEV1). An inverse relationship emerged between forced vital capacity (FVC) and years of exposure to airborne silica. In the workplace Mina Subterrànea (MT-3600), statistically significant inverse relationship emerged between the Tiffeneau index and body weight. Conclusions: The working conditions in the mining industry in altitude appeared to be potentially pathogenic; further investigations should be realized integrating risk assessment protocols even in consideration of their undeniable unconventionality.

Objectives The aim of the study was to assess the nutritional status and diet of midwives working on a shift schedule in public hospitals in Wrocław, Poland, and to analyze the variation in their diet according to their working hours (day shift, night shift) and on a non-working day. Material and Methods In the group of 50 midwives, employed in 4 public hospitals in Wrocław weight and body composition, waist and hip circumference, waist-hip-ratio and BMI were assessed. The nutritional habits and quality of the study participants’ diets were assessed by 3-days food dietary recall, including 1 day shift day, 1 night shift day, and 1 non-working day. Results More than half of the subjects were assessed as having excess body weight (BMI ≥25 kg/m2). Thirty percent of participants had BMI ≥25–<30 kg/m2 and 24% BMI ≥30 kg/m2, 70% had a body fat percentage >30%. Fifty-six percent of the diets had an energy value <90% of the subject’s total daily energy expenditure. Significantly higher energy value of diets on the night shift day compared to the morning shift day (1959.05±596.09 kcal vs. 1715.36±654.55 kcal, p = 0.01) were observed. The same relationship applied to cholesterol content (349.50±155.33 mg vs. 261.39±190.59 mg, p = 0.002). A high intake of phosphorus and sodium, exceeding the recommended dietary intake, was noticed. Conclusions The occurrence of a night shift in the shift work schedule is an element of that model that may have a significant impact on the nutritional and health value of shift workers’ diets. Therefore, it seems reasonable to implement nutritional education programs promoting healthy eating choices and habits during night work.

Shift work is an important source of health disturbances. Night work has a negative influence on some spheres: biological, working, social, and medical. Disturbances of sleeping, one group of manifestations of medical problems, can be considered as a cause of health deterioration. This study focuses on the occurrence of breathing disturbances during sleep in shift workers. Twenty one shift worked police officers (40-60 years old) were compared with an age-matched control group operating in the some environment. All subjects underwent overnight polysomnography. The polysomnographic investigation by shift workers was conducted after a day shift and normal night sleep, after an adaptational night in the sleep laboratory. Obstructive sleep apnea was found in 8 shift workers (38%) with AHI of 5.72-45.45 and in 8 control volunteers (38% of the studied group) with AHI of 5.00-25.24. All breathing parameters, as measured by polysomnography, did not differ between the two groups. Our results do not confirm the hypothesis that chronic irregular work hours promote the occurrence of obstructive sleep apnea in subjects aged 40-60 years.

Wstęp. Pielęgniarstwo to zawód obciążony wieloma czynnikami. Jednymi z wielu problemów jest praca zmianowa, narażenie na zmęczenie, problemy ze snem, bezsenność. Do czynników społecznych zaliczyć można błędy w komunikacji między personelem i pacjentem. W pracy przybliżono zagadnienie zespołu przewlekłego zmęczenia. Cel. Celem pracy jest ocena chronicznego zmęczenia i bezsenności wśród pielęgniarek oraz określenie jaki wpływ mają one na relacje w zespole pielęgniarskim. Materiał i metody. Populacją, która została poddana badaniu była grupa 100 pielęgniarek pediatrycznych, chirurgicznych, internistycznych oraz podstawowej opieki zdrowotnej. Narzędziami były: Skala Zmęczenia Chronicznego (FAS), Ateńska Skala Bezsenności (AIS), kwestionariusz ankiety własnego autorstwa. W pracy wykorzystano metodę sondażu diagnostycznego oraz metodę szacowania. Wyniki. Blisko połowa pielęgniarek w grupie badanej miała objawy zmęczenia chronicznego, a 36% pielęgniarek w grupie badanej przejawiała bezsenność. Wnioski. Chroniczne zmęczenie pielęgniarek często jest spowodowane specyfiką oddziałów, na których pracują. Na bezsenność wpływa praca zmianowa, która zwiększa odczuwanie zmęczenia i desynchronizuje biologiczny zegar. Lata stażu nie wpływają znacząco na poziom zmęczenia i senności pielęgniarek. Na bezsenność wpływa praca zmianowa oraz zła organizacja pracy.

Background: Several studies have shown an association between work-related stress and risk factors for cardiovascular disease. However, only a few studies concerned the police. The aim of this study was to assess the relationship between the general and work-related stress, and the functioning of the circulatory system in the police staff. Material and Methods: The study group consisted of 126 policemen (aged 37.8±7.3 years), with average employment duration of 14.4±7 years. The study comprised the assessment of health status based on the medical examination and medical history of identified diseases, cardiovascular risk factors and symptoms, dietary habits, physical activity, intake of drugs, data on the family history, determinations of serum total cholesterol, HDL and LDL fractions, triglycerides, and fasting glycemia. The stress level was assessed using the Questionnaire for the Subjective Assessment of Work and Perceived Stress Scale. Results: On medical examination hypertension was found in 36% of the people under study. Chest discomfort was reported by 60% of the subjects. Average body mass index (BMI), serum cholesterol and LDL were elevated (22.7±4.1, 222.6±41.7 mg/dl and 142.7±39.7 mg/dl, respectively). Mean triglyceride, HDL fraction and fasting glucose levels were normal in the whole group. The levels of general and occupational stress were 34.9±4.8 and 128.0±33.3, respectively, being higher than in other occupational groups. In the group with the highest level of stress, there were significantly more people with circulatory problems (81%), drinking strong alcohol at least once a week (27%), working in a 3-shift system (40.5%) and working overtime (44%). Conclusions: The results show that the police are a group at high risk of developing cardiovascular diseases due to work-related stress. Med Pr 2013;64(3):335–348

Wprowadzenie: W wielu badaniach wykazano związek między stresem związanym z pracą a czynnikami ryzyka chorób układu krążenia. Tylko nieliczne z nich dotyczyły policjantów. Cel pracy: Celem pracy była ocena związku między stresem ogólnym i zawodowym a funkcjonowaniem układu krążenia u policjantów. Grupa badana: Badania przeprowadzono u 126 policjantów w wieku 37,8±7,3 lat, o średnim stażu pracy: 14,4±7 lat. Metody: Badanie obejmowało: ocenę stanu zdrowia na podstawie badania lekarskiego i wywiadu dotyczącego stwierdzonych chorób, czynników ryzyka i dolegliwości ze strony układu krążenia, nawyków żywieniowych, aktywności fizycznej, używek oraz wywiadu rodzinnego, badania stężenia cholesterolu całkowitego, frakcji HDL (high density lipoprotein - lipoproteina wysokiej gęstości) i LDL (low density lipoprotein - lipoproteina niskiej gęstości), trójglicerydów i glikemii na czczo. Poziom stresu oceniano z zastosowaniem „Kwestionariusza do subiektywnej oceny pracy” i Skali Spostrzeganego Stresu. Wyniki: Nadciśnienie tętnicze w badaniu lekarskim stwierdzono u 36% osób. Dolegliwości w klatce piersiowej zgłaszało 60% osób. Średni wskaźnik masy ciała (body mass index - BMI), stężenie cholesterolu i frakcji LDL było podwyższone (odpowiednio: 22,7±4,1; 222,6±41,7 mg/dl i 142,7±39,7 mg/dl). Średnie stężenie triglicerydów, frakcji HDL i glukozy na czczo w całej grupie było w normie. Poziom stresu ogólnego i zawodowego był wyższy niż w innych grupach zawodowych (wynosił odpowiednio: 34,9±4,8 i 128,0±33,3). W grupie o najwyższym poziomie stresu istotnie więcej było osób z dolegliwościami ze strony układu krążenia (81%), spożywających mocny alkohol co najmniej raz w tygodniu (27%), pracujących w systemie 3-zmianowym (40,5%) i w godzinach nadliczbowych (44%). Wnioski: Wyniki badania wskazują, że policjanci są grupą o wysokim ryzyku sercowo-naczyniowym związanym ze stresem zawodowym. Med. Pr. 2013;64(3):335–348

The aim of this study was to investigate the synergistic effects of physical demands and shift working on low back disorders (LBDs) among nursing personnel. The study used 2 questionnaires: a self-administered questionnaire composed of parts of Nordic musculoskeletal questionnaire to assess LBDs and job content questionnaire to assess physical demands. The participants were divided into 4 groups: from group 1 (low physical demands day workers) to group 4 (high physical demands shift workers). In regression analysis, high physical demands were associated with the prevalence of LBDs independently (OR 4.4, 95% CI [2.40, 8.00] and p < .05), but there was no association between shift working and LBDs (p > .05). Odds ratio in high physical demands shift workers was 9.33 compared to the reference group (p < .001). Calculated synergistic index was 7.37. Simultaneous impacts of shift working and high physical demands may increase the prevalence of LBDs among nursing personnel.

Background. Shift work may affect the occurrence and severity of hypertension, ischemic heart disease and dyslipidemia. The aim of the study was to assess the prevalence of ischemic heart disease, hypertension and dyslipidemia in shift workers. Material and methods. The study was carried out in the Bogdanka mine in Łęczna, Poland. The questionnaire, which was designed by the author of this work, was conducted among 700 shift workers who worked underground in the mine. Statistical analysis was performed using STATISTICA v. 7.1 (StatSoft, Poland) software. Results. Participants who believed that shift work may lead to deterioration of their health also believed that it may affect the occurrence of ischemic heart disease and hypertension. Almost one in four respondents had blood pressure values of > 139/89 mmHg. Almost one in ten respondents was receiving treatment for hypertension. A small number of respondents reported abnormal total cholesterol, HDL cholesterol and triglyceride levels. Conclusions. In the opinion of respondents, shift work can exacerbate hypertension and ischemic heart disease. Abnormal values of total cholesterol and its LDL and HDL fractions increased with age and length of work, while abnormal triglyceride values were reported most frequently by supervisors. It seems necessary to introduce training for shift workers, aimed at presenting them with the principles of prevention of cardiovascular diseases; for example, how to deal with stress, change eating habits, stop smoking and reduce coffee intake, and how to encourage physical activity and good sleep hygiene.

Wprowadzenie. Praca zmianowa ma wpływ na występowanie i zaostrzenie nadciśnienia tętniczego, choroby niedokrwiennej serca, czy nieprawidłowych wartości lipidogramu. Celem pracy była ocena występowania u pracowników zmianowych choroby niedokrwiennej serca, nadciśnienia tętniczego i zaburzeń lipidogramu. Materiał i metody. Badanie przeprowadzono w kopalni “Bogdanka” w Łęcznej. Kwestionariusz własnej konstrukcji rozdano wśród 700 podziemnych pracowników zmianowych. Analizę statystyczną otrzymanych wyników przeprowadzono w oparciu o program statystyczny STATISTICA v. 7.1 (StatSoft, Polska). Wyniki. Osoby potwierdzające, że praca zmianowa może prowadzić do pogorszenia stanu zdrowia, uważały, że może ona wpływać na występowanie zaostrzeń choroby niedokrwiennej serca i nadciśnienia tętniczego. Prawie co czwarty ankietowany miał wartości ciśnienia > 139/89 mmHg. Prawie co dziesiąty ankietowany leczył się na nadciśnienie tętnicze. Nieliczny odsetek ankietowanych zaobserwował u siebie nieprawidłowe wartości cholesterolu HDL, TGL oraz cholesterolu całkowitego. Wnioski. W ocenie respondentów praca zmianowa może być przyczyną zaostrzenia nadciśnienia i choroby niedokrwiennej serca. Występowanie nieprawidłowych wartości całkowitego cholesterolu i jego frakcji LDL i HDL wzrastało wraz z wiekiem i długością pracy, natomiast nieprawidłowe wartości TGL najczęściej zgłaszały osoby sprawujące nadzór. Wydaje się koniecznym wprowadzenie szkoleń dla pracowników zmianowych, mających na celu przedstawienie im zasad profilaktyki w chorobach sercowo naczyniowych, przykładowo: jak radzić sobie ze stresem, jak zmienić nawyki żywieniowe, zaprzestanie palenia papierosów i picia kawy, dobrze prowadzona aktywność fizyczna, dobra higiena snu.

The system of human activity, which is established by genetics and regulated by outer and inner factors, is associated with many characteristics which maintain the body in the best condition and ensure appropriate life quality. Objective. To evaluate of life quality among male shift-workers. Methods: Research based on a self-devised questionnaire, conducted among 700 shift-workers, followed by statistical analysis of the results. Results. Nearly a half of respondents (43.00%) reported that shift-work influences the quality of their family life. Remarkably, such an opinion was often stated by people with children (46.01%) p<0.05, the divorced (58.22%), married people (44.74%) and bachelors (25.33%), respectively. Fathers usually indicated lack of contact with their family as well as irregular consumption of meals (66.91%). Almost every third respondent noted that their shift type of work negatively influence their sexual life (31.14%). Conclusions. It was shown that shift-work negatively influences the respondents’ life quality in the form of deterioration of the quality of family life; the respondents, regardless of marital status, age and having children, most often complained about the lack of contact with the family and irregular eating with them; negative influence on sexual life, which was the case in one-third of respondents. In order to encourage healthy behaviour and increase the quality of life of people performing shift-work, training and programmes should be introduced. These would help shift- workers to adjust their work time to their family and social life.

Time-related accident risk in shift work may be attributed to internal factors, such as fatigue, level of performance, sleep propensity, and to some external factors, like shift system, physical and social environment. Six hundred and sixty-eight events in the metallurgical industry have been analysed in terms of time of day, time on task, consecutive day of the shift block, day of the week, and season. The injury rate was similar on all shifts but more severe accidents happened in the nighttime. Somewhat more injuries occurred in the second half of the shift, in the second part of a shift block, and in summer compared with winter. There were fewer injuries at weekends.

The aim of the present study was to estimate spillover effects between the work and the family sphere in a sample of nurses (N = 2058). Hierarchical regression analyses investigated whether shift work schedules were associated with negative or positive spillover, both from family to work and vice versa, controlling for demographic factors, job demands and decision latitude. With daytime work as a reference group, all types of shift work (day and evening shift, night shift only and rotating 3 shift) were associated with higher negative work–to–family spillover.Night work was associated with significantly less negative family–to–work spillover. None of the different shift work schedules were related to any type of positive spillover. The results indicate that working outside of daytime hours is less compatible with workers’ family lives, compared to working ordinary day shifts. On the other hand, working night shifts only was associated with reduced negative family–to–work spillover.

Potencjalne ryzyko dla zdrowia rotacyjnego pracownika zmianowego można przypisać do dwóch głównych kategorii: związanej z zaburzeniami cyklu okołodobowego skutkującego nieregularnym cyklem snu i czuwania i związanej z ostrym hamowaniem wydzielania melatoniny po ekspozycji na światło niebieskie. Innym istotnym czynnikiem ryzyka pracowników zmianowych jest występujące u nich nadmierne zmęczenie i bezsenność, które w efekcie mogą prowadzić do ograniczenia wydajności pracy, popełniania błędów i wypadków przy pracy. Celem niniejszego artykułu jest przedstawienie aktualnej wiedzy dotyczącej zastosowania pozawzrokowego oddziaływania światła na organizm człowieka do celów projektowania oświetlenia skutecznego biologicznie na stanowiskach pracy zmianowe.
