Objectives: Night shift work has been linked to some chronic diseases. Modification of lifestyle by night work may partially contribute to the development of these diseases, nevertheless, so far epidemiological evidence is limited. The aim of the study was to explore association between night shift work and lifestyle factors using data from a cross-sectional study among blue-collar workers employed in industrial plants in Łódź, Poland. Material and Methods: The anonymous questionnaire was self-administered among 605 employees (236 women and 369 men, aged 35 or more) -434 individuals currently wor king night shifts. Distribution of the selected lifestyle related factors such as smoking, alcohol drinking, physical activity, body mass index (BMI), number of main meals and the hour of the last meal was compared between current, former, and never night shift workers. Adjusted ORs or predicted means were calculated, as a measure of the associations between night shift work and lifestyle factors, with age, marital status and education included in the models as covariates. Results: Recreational inactivity (defined here as less than one hour per week of recreational physical activity) was associated with current night shift work when compared to never night shift workers (OR = 2.43, 95% CI: 1.13-5.22) among men. Alcohol abstinence and later time of the last meal was associated with night shift work among women. Statistically significant positive relationship between night shift work duration and BMI was observed among men (p = 0.029). Conclusions: This study confirms previous studies reporting lower exercising among night shift workers and tendency to increase body weight. This finding provides important public health implication for the prevention of chronic diseases among night shift workers. Initiatives promoting physical activity addressed in particular to the night shift workers are recommended.
StreszczeniePraca w nocy prawdopodobnie odgrywa rolę w etiologii chorób przewlekłych poprzez zaburzenie rytmu okołodobowego, obniżenie syntezy melatoniny i niedobory snu. Celem naszej pracy był przegląd badań epidemiologicznych dotyczących związku między pracą w nocy a występowaniem wybranych patologii u pielęgniarek i położnych. Przeglądu dokonano na podstawie publikacji zawartych w bazie Medline, opublikowanych do czerwca 2012 r. Podstawę przeglądu stanowiły artykuły naukowe opisujące wyniki badań przekrojowych (prawie 2/3 wszystkich prac) oraz badań kohortowych (prospektywnych). Zidentyfikowałyśmy ogółem 26 prac oryginalnych, w tym 5 badań epidemiologicznych dotyczących chorób/zaburzeń czynnościowych układu pokarmowego, 3 -zespołu metabolicznego, 2 -cukrzycy typu 2, 9 -chorób układu krążenia i czynników ryzyka chorób układu krążenia, 5 -otyłości/nadwagi, 2 -zaburzeń miesiączkowania i 3 -zaburzeń przebiegu ciąży. Z przeprowadzonej analizy piśmiennictwa wynika, że praca pielęgnia-rek i położnych na zmianach nocnych, w systemie rotacyjnym, najsilniej łączy się ze wzrostem ryzyka otyłości i nadwagi. W każdym z przeanalizowanych przez nas 5 badań dotyczących tego zagadnienia obserwowano omawianą zależność (potwierdzoną istotnością statystyczną wyników), także po uwzględnieniu czynników zakłócających. Sugestywne są także wyniki dotyczące cukrzycy typu 2 i zaburzeń cyklu menstruacyjnego. Dane epidemiologiczne dotyczące pozostałych, omawianych w pracy zaburzeń lub patologii wydają się mniej pewne -podawane wyniki są niespójne lub liczba danych jest zbyt mała, aby można było formułować zdecydowane wnioski. Wskazane jest prowadzenie dalszych badań epidemiologicznych pielęgniarek i położnych pracujących w nocy, w szczególności obserwacji prospektywnych, które pozwolą ustalić, czy potencjalny związek pracy w nocy z omówionymi problemami zdrowotnymi ma charakter przyczynowo-skutkowy. Med. Pr. 2013;64(3):397-418 Słowa kluczowe: pielęgniarki, położne, praca w nocy, zdrowie, choroba AbstractNight shift work has been thought to play a role in the etiology of chronic diseases through a disruption of the circadian rhythm, decreased synthesis of melatonin and sleep deprivation. Our aim was to review the epidemiological studies on the association between night shift work and some pathologies in nurses and midwives. We reviewed publications available in the MEDLINE database and published before June 2012, describing the cross-sectional (almost two thirds of all papers) and cohort studies. In total, we identified 26 original papers, including 5 epidemiological studies addressing diseases or disorders of the digestive system, 3 -metabolic syndrome, 2 -type 2 diabetes, 9 -cardiovascular diseases and CVD risk factors, 5 -obesity/overweight, 2 -menstrual disorders and 3 -poor pregnancy outcomes. The analysis of the literature indicates that night shift work of nurses and midwives is most strongly associated with a higher risk of obesity/overweight. In each of the five studies, which we identified this association was observed (confirme...
Objectives: Night shift work involving circadian rhythm disruption has been classified by IARC as a probably carcinogenic to humans (Group 2A). Little is known about co-exposures of the night shift work in occupational settings. The aim of our study was to characterize night shift work systems and industrial exposures occurring in the manufacturing plants in Łódź, Poland, where night shift work system operates, with particular focus on potential carcinogens. Material and Methods: Data on the night shift work systems and hazardous agents were collected through survey performed in 44 enterprises. The identified hazardous agents were checked using the IARC carcinogen list, and the harmonized EU classification of chemical substances. We also examined databases of the Central Register of Data on exposure to substances, preparations, agents and technological processes showing carcinogenic or mutagenic properties in Poland. Results: The most common system of work among studied enterprises employed 3 (8-hour) shifts within a 5-day cycle. We identified as many as 153 hazards occurring in the environment of the plants, with noise, carbon monoxide and formaldehyde recorded as the most common ones. Out of these hazards, 11 agents have been classified by IARC to group 1 -carcinogenic to humans, whereas 10 agents have been classified as carcinogens by the regulation of European Classification of carcinogens. Analysis of the data from the Central Register revealed that 6 plants reported presence of carcinogens in the environment of work. Conclusions: In our study we observed that in none of the workplaces the night shift work was a single exposure. Further epidemiological studies focusing on investigation of health effects of the night shift work should identify occupational co-exposures and examine them as potential confounders.
were males. Of the males 37.8% (n = 189) were regular smokers, while 24.6% (n = 123) consumed alcohol daily.The prevalence of shoulder pain, wrist/hand pain, knee pain, neck pain and back pain in the past one month was 4.4% (n = 32), 4.5% (n = 33), 5.4% (n = 39), 4.7% (n = 34) and 6.1% (n = 44) respectively. Workers working in fabricated metal product industries had the highest proportion of having shoulder pain (7.4%, n = 07). In the same category wrist/ hand pain was 10.5% (n = 10) and knee pain was 9.5% (n = 09). Thirty one (4.3%, n = 31) were having asthma prior to the study.The prevalence of wrist pain (p = 0.025) and knee pain (p = 0.006) were significantly associated with the industry category. Sex of the worker was not significantly associated any musculoskeletal disorders assessed. Conclusion Musculoskeletal diseases are prevalent among the study population. This needs to be investigated in-depth to identify the correlates to plan interventions. Objective The purpose of this study was identify the determinants of fatigue. Methods A cross-sectional study in 153 medic residents' volunteers from diverse specialties at a high specialty medical unit of the Mexican Institute of Social Security was conducted. Sociodemographic and job information were collected. The presence of stress, burnout, depression and fatigue were assessed, as well as unfavorable psychosocial factors, violence and quality of working life at risk. The model of fatigue stress determinants was adopted and a multiple logistic regression model for that purpose was completed. Results 27% (153) took part. 61.4% referred depression and 50.3% mentioned loss interest for daily activities. From 28 to 74% pointed adverse psychosocial factors at work; 93.5% reported presence of violence. Of 8.5 to 89% had working life with poor conditions; 61.4% had stress, 63.4% fatigue, and 32.7% burnout syndrome. In multiple logistic regression model, stress, OR: 8.9 (95% CI: 3.4-23.2, p <0.001), burnout, OR: 3.4 (95% CI: 1.02-11.4, p = 0.045), psychological demands at work, OR: 4.2 (95% CI: 1.5-12.1, p = 0,007), and depression, OR 2.9 (95% CI: 1.12-7.7, p = 0.028) were identified as determinants of fatigue. Conclusions The job stress persistence can lead to chronic fatigue syndrome, and this probably is affecting the quality medical care afforded. Objective To identify seropositivity for influenza A (H1N1) pdm09 in Social Security Mexican Institute (IMSS) health staff in the Valley of Mexico. Methodology Two stages cross sectional study was conducted on a random sample of pre-vaccination and post-vaccination against pandemic virus IMSS workers from Valley of Mexico and by job category. A social and labour questionnaire was applied and presence of antibodies against influenza A (H1N1) pdm09 in serum neutralisation test for pandemic virus retroviral pseudotypes, were determined. Two logistic regression models to identify risk factors in both stages were conducted. Results 1378 workers from 13 workplaces, with 41.7 years of age average and 68.7% (947) of them women...
Objective Night shift work has been linked to a higher incidence of some chronic diseases such as gastrointestinal or cardiovascular diseases. This is the first study assessing the prevalence of selected diseases and symptoms among middle-aged Polish night shift workers. Methods We conducted a cross-sectional study of 605 blue collar workers in plants operating based on a shift system in Łódź, Poland. The study included 434 night shifts workers and 171 day-only workers (369 men and 236 women), aged 35–65. The employees coming to a periodic health examination to occupational physicians were invited to participate in the study. The data were collected via a self-administered questionnaire based on the “Standard Shiftwork Index”. Crude frequencies of occurrence of particular diseases and symptoms were calculated. Results The mean age of the night shift workers and the day workers were similar, i.e. 47.6 and 46.6 years, respectively (p = 0.13). Hypertension (14.7%), high cholesterol/hypercholesterolemia (10.9%) and chronic back pain (10.9%) were the most common diseases in this population. The prevalence of hypertension (14.3% among the night shift workers) and gastric ulcer (6.0%) was slightly higher than in the general population in Poland in a similar age group (hypertension ~ 12% and gastric ulcer ~ 4%). The prevalence of irritable bowel syndrome (IBS) (1.2% among the night shift workers), coronary heart disease (CHD) (1.2%) and high cholesterol (9.9%) were slightly lower among the industrial workers compared to the general population in Poland (IBS ~ 13%, CHD ~ 5% and high cholesterol ~ 60%). Conclusions Our study suggest some associations among Polish workers for the diseases potentially linked to night shift work, however further analyses are necessary (with adjustment for important confounders) to confirm these preliminary findings.
