The aim of this study was to evaluate the oxidative stress and metabolic activities of nurses working day and night shifts. Intensive care unit (ICU) (n=70) and ordinary service (OS) nurses (n=70) were enrolled in the study. Just before and the end of the shifts, blood samples were obtained to measure the participants' oxidative stress parameters. Metabolic activities were analyzed using the SenseWear Armband. Oxidative stress parameters were increased at the end of the shifts for all OS and ICU nurses compared to the beginning of the shifts. Compared to the OS nurses, the ICU nurses' TAS, TOS, and OSI levels were not significantly different at the end of the day and night shifts. The metabolic activities of the OS and ICU nurses were found to be similar. As a result, the OS and ICU nurses' oxidative stress parameters and metabolic activities were not different, and all of the nurses experienced similar effects from both the day and night shifts.
Relationship between intensity of night shift work and antioxidant status in blood of nurses
International Archives of Occupational and Environmental Health, 2013
Purpose Light-at-night exposure can disrupt the human circadian rhythm via clock gene expressions. The circadian rhythm influences antioxidant enzymes' activity and cellular mRNA levels of these enzymes. The employees working based on a shift system adjust to the changes occurring both on the cell level and on the level of the whole organism. Therefore, a question should be answered whether shift work disturbs oxidant-antioxidant balance and/or generates oxidative stress. Methods A cross-sectional study was conducted among nurses selected from the Local Registry of the Chamber of Nurses and Midwives in Lodz: 359 nurses worked daily only and 349 working rotating night shifts. These two groups differed significantly in respect of age (p \ 0.0001), menopausal status (p \ 0.0001), and current smoking habit (p = 0.02). The average total work duration was significantly shorter (12.4 years) in nurses working currently rotating night shifts who worked significantly longer on night shifts than day-workers (26.6 years). Results We found statistically significant higher red blood cell glutathione peroxidase in nurses working on night shifts (21.0 ± 4.6 vs. 20.0 ± 5.0 U/g Hb, p \ 0.009) after adjusting for age, oral contraceptive hormone use, smoking, and drinking alcohol during last 24 h. Statistically significant lower vitamin A and E levels were found in the premenopausal women working in rotating system (0.690 ± 0.238 vs. 0.786 ± 0.262 lg/ml, p \ 0.0001 for vitamin A and 10.93 ± 4.15 vs. 12.78 ± 4.75 lg/ml, p \ 0.0001 for vitamin E). The marker of lipid peroxidation (TBARS concentration) was significantly lower in the premenopausal nurses than postmenopausal ones working day shifts only (2.06 ± 0.76 vs. 2.21 ± 0.80 nmol/ml, p \ 0.038). We observed that erythrocyte GSH-Px activity rose statistically significant in nurses working more night shifts per month (p \ 0.01). Conclusions The results quoted above seem to support the existence of an association between light-at-night exposure and blood glutathione peroxidase activity in female shift workers. Nevertheless, in order to explain the mechanisms of this association, we need more studies.

Healthcare industry employees, work in rotating shift duties to provide 24/7 services. Shift work is known to disrupt circadian rhythm and predispose the employees to metabolic risk and oxidative stress, subsequently increasing the risk for Non-Communicable Diseases. Present study attempts to evaluate this association. Aims: To evaluate the association between metabolic risk and oxidative stress among health care personnel working in rotating night-shift as compared to dayshift. Settings and design: Cross sectional study. Methods and materials: Eligible 124 employees [(night shift (61), Day shift (63)] working in a tertiary care hospital in Bengaluru were randomly selected and tested for anthropometric and laboratory parameters pertaining to metabolic risk and oxidative stress and categorized accordingly using standard criteria. Statistical tests (student t-test) were applied to test for association between shift work, metabolic risk and oxidative stress. Results: Metabolic risk and Oxidative stress were significantly higher in rotating night shift workers as compared to day shift (p < 0.001) and (p < 0.017) respectively. Conclusion: Rotating night shift work is associated with increase in metabolic risk and oxidative stress and there is a need to consider this enhanced risk during periodical medical examination and employee health interventions. There is a need for further research to quantify risk for metabolic risk and understand this association in other occupations as well.
Investigating the relationship between job stress, workload and oxidative stress in nurses
International Journal of Occupational Safety and Ergonomics, 2021
Objectives. Occupational stress and workload are common risk factors among nurses that increase absenteeism, reduce the quality and quantity of patient care, increase care costs and increase the patient safety risk. The relation between these risk factors and oxidative stress levels has not been clearly defined. Methods. This study was conducted with 258 participants (126 nurses as the case group and 132 healthy adults as the control group). Information was collected using a demographic questionnaire, the nurses’ occupational stress scale and the NASA task load index workload questionnaire. Blood samples were taken from the participants and then the levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase and total antioxidant capacity (TAC) were measured in the serum samples. Independent t tests and one-way analysis of variance were used for statistical analysis. Results. SOD and TAC were significantly higher and MDA was significantly lower among the case group compared to the control group. TAC levels significantly decreased with increased stress. MDA levels showed negative associations with stress and workload. Nurses experience high levels of occupational stress and workload. Conclusion. Biomarkers such as SOD, TAC and MDA are the most important predictors of work stress and overwork in this study.
Neuroendocrine, immune and oxidative stress in shift workers
Sleep Medicine Reviews, 2013
Shift work is commonly associated with disturbed life rhythms, resulting in chronic exposure to circadian desynchronization and sleep restriction. Epidemiological data have shown that shift workers are at an increased risk of cardiovascular disease and breast cancer. In this review, we will explore how observed increases in neuroendocrine stress, non-specific immune responses and pro-oxidative status could act as biological mediators for these damaging health risks in shift workers. To explain these risks, compelling evidence from laboratory studies links circadian misalignment but also sleep restriction to disruptions in the neuroendocrine, immune and oxidative stress systems. Assessment of neuroendocrine, oxidative and immune stress in the shift worker population is still a limited and novel field, which may have considerable clinical relevance. Finally, we will consider the potential benefits of a countermeasure, such as napping, in minimizing the neuroendocrine and immune stress and cardiovascular risk imposed by shift work.
Psychosocial work environment and oxidative stress among nurses
Journal of Occupational Health
Background: Work stress among nurses has increased in recent years due to the demands of clinical nursing. Objectives: To investigate psychosocial work stress among nurses using the effort-reward imbalance (ERI) model with assessment malondialdehyde (MDA) as an oxidative stress marker and total antioxidants. Methods: The present study was conducted on 204 registered nurses worked at two tertiary hospitals in Menoufia governorate, Egypt through the period from the 1st of February to the end of July 2016. Two questionnaires were applied including general demographic and occupational histories as well as effort-reward questionnaire. Blood analysis was performed to assess MDA and total antioxidant levels. Results : ERI was prevalent among the study participants (72.5%). ERI was more prevalent among young married nurses who worked more than 10 years. Nurses that worked at ICUs complained more of ERI (43.2%) while nurses that worked at operation rooms complained more of overcommitment (62.5%). MDA levels were significantly positively correlated with E/R ratios (rho = 0.350, P !0.001). Conclusions : Work stress was prevalent among the studied nurses as revealed by the high ERI and MDA levels. Young married female nurses complained more of work stress. ICUs and operating rooms were the most stressful departments at the studied hospitals. Hence, implementing programs and strategies that eliminate stressful working conditions at hospitals is critical to the reduction and prevention of work stress among nurses.

Zagazig University Medical Journal
Background: Nursing is highly demanding and stressful profession. Job stress was found to be a stronger predictor of oxidative stress activity causing elevation of blood oxidative biomarkers. This work aimed to improve mental and psychological health of nurses through identification of prevalence of work stress among nurses at Zagazig university hospitals (ZUHs) and assess the association between work stress and blood oxidative biomarkers. Methods: A comparative cross-sectional study was conducted among 40 nurses and 40 administrative workers at ZUHs. Both two groups were subjected to a structured questionnaire about sociodemographic data and occupational history and two standardized questionnaires about job stress followed by laboratory investigations to measure blood oxidative biomarkers (Malonaldehyde MDA & Superoxide dismutase SOD). Results: This study showed that job stress and its level were significantly higher among nurses compared to their controls. this study indicated that prevalence of job stress in nurses at ZUHs was 85.0% compared to 22.5% in administrative controls where 65.0% and 20.0% of them had severe and moderate stress compared to 7.5% and 15.0% among controls. Furthermore, this study showed significantly high level of both blood oxidative biomarkers as both levels of MDA, [ Median (3.18) mol/ml] and SOD, [X±SD: 4.27± 0.40 U/ml] were significantly higher among nurses compared to their controls Conclusion: Job stress is realistic and widespread phenomena among nurses in ZUHs that have devastating consequences on nurse's health thus, effective preventive strategies should be designed and implemented.
