Background: This study explored the impact of occupational stress, personal factors, and physical conditions on work productivity decline (WPD) among workers in the Tunisian onshore oil and gas industry.
Methods: We conducted a cross-sectional survey among 246 onshore oil installation workers of a Tunisian private oil company. 94 employees (48%) participated in this study. We used the Job Content Questionnaire to evaluate occupational stress and the Work Productivity and Activity Impairment Questionnaire to assess the WPD.
Results: Data were analysed using R software. This study exclusively included male workers, with an average age of 41.1 ± 9.5 years. Binary logistic regression analysis identified low social support and job-strain situation as the most associated risk factors (OR >3). The random forest model suggested that professional category, job-strain situation, low social support, and iso-strain situation were the most important variables in predicting WPD.
Conclusion: These data provided evidence that petroleum workers faced a monotonous lifestyle in the workplace, leading to high levels of occupational stress that affected their work productivity. This study is the first in Tunisia in the oil sector.
Background: It is seen that information technology (IT) professionals are at higher risk of developing mechanical low back pain due to numerous factors such as a sedentary lifestyle, attaining inappropriate posture for a prolonged period of time, work stresses, and inadequate exercise which lead to overload on the back musculature. Working from home has become the new normal for these professionals in which they attain abnormal posture which leads to pressure on the muscles and thus there is a need to estimate and analyze spinal muscle performance among IT professionals.
Materials and methods: Our main objectives were to estimate the spinal muscle performance in work-from-home IT professionals of Karad and to find the association between spinal muscle performance with respect to age, gender, and body mass index (BMI). Depending on inclusion and exclusion criteria, 120 IT professionals working from home were selected for this study by simple random sampling. Written consent was taken and a detailed outcome assessment was done by using the static and dynamic abdominal test, extensor test, internal/external oblique test, and back rotators test. Also, functional performance was measured using the back performance scale. SPSS version 20 was used to carry out the analysis of data and results were obtained.
Results: In participants of sample size 120 (100%), 27 (26%) were normal, 30 (32%) good, 24 (20%) fair, 21 (14%) poor, 18 (8%) trace; whereas, static extensor strength was 16 (12%) normal, 9 (18%) good, 24 (28%) fair, 18 (36%) poor, 3 (6%) trace. For oblique's, static strength was 10 (20%) normal, 12 (24%) good, 15 (30%) fair, 9 (18%) poor, 4 (8%) trace; whereas, for back rotators strength was 10 (20%) normal, 17 (34%) good, 15 (30%) fair, 8 (16%) poor. The mean number of repetitions for the dynamic endurance test for extensors was 11, for abdominals wase 24 and for obliques was 12. A back performance scale was found with a minimum score of 6 and a maximum score of 11 for activity limitation. There was statistically significant found to be between spinal muscle performance and age (P = 0.041), BMI (P = 0.027).
Conclusion: In this study it was found that spinal muscle performance was decreased in IT professionals. It was concluded that there was a significant reduction in static extensor performance compared to static abdominal muscle performance. Also, the spinal muscle performance of extensors was less as compared to that of abdominals. The data also revealed that there was a remarkable association that was seen between spinal muscle performance and age as well as spinal performance and BMI.
Context: Pollution-related health hazards are very common among people living and/or working in industrial areas, particularly near industries and metro cities. These air pollutants contribute to allergens, increase inflammation, and affect lung function.
Aim: The present study aimed to examine the effect of yoga training on lung functions and inflammation in terms of soluble interleukin-2 receptor (sIL-2R) in people working and living in a polluted area.
Settings and design: This is a randomized controlled interventional pilot study.
Methods and materials: Forty-eight male volunteers from the industrial area, aged 20-50 years, were randomly assigned to the experimental group and the control group. Each group comprises 24 study participants. Lung function and sIL-2R were studied at the baseline and post-yoga intervention period of 16 weeks.
Statistical analysis used: Study data were analyzed using descriptive methods, a one-tailed t-test, a paired t-test, and an independent t-test.
Result: Study results showed directional and significant improvements in forced vital capacity, forced expiratory volume in the first second, and peak expiratory flow rate compared to the control group participants. The results pertaining to sIL-2R showed a directional and significant decrease in the experimental group compared to the control group.
Conclusion: The present study showed that yoga helps to promote better health, improve lung function and reduce inflammation among people residing in polluted environments.
Aluminum, the third most abundant metal present in the earth's crust, is present almost in all daily commodities we use, and exposure to it is unavoidable. The interference of aluminum with various biochemical reactions in the body leads to detrimental health effects, out of which aluminum-induced neurodegeneration is widely studied. However, the effect of aluminum in causing dyslipidemia cannot be neglected. Dyslipidemia is a global health problem, which commences to the cosmic of non-communicable diseases. The interference of aluminum with various iron-dependent enzymatic activities in the tri-carboxylic acid cycle and electron transport chain results in decreased production of mitochondrial adenosine tri-phosphate. This ultimately contributes to oxidative stress and iron-mediated lipid peroxidation. This mitochondrial dysfunction along with modulation of α-ketoglutarate and L-carnitine perturbs lipid metabolism, leading to the atypical accumulation of lipids and dyslipidemia. Respiratory chain disruption because of the accumulation of reduced nicotinamide adenine di-nucleotide as a consequence of oxidative stress and the stimulatory effect of aluminum exposure on glycolysis causes many health issues including fat accumulation, obesity, and other hepatic disorders. One major factor contributing to dyslipidemia and enhanced pro-inflammatory responses is estrogen. Aluminum, being a metalloestrogen, modulates estrogen receptors, and in this world of industrialization and urbanization, we could corner down to metals, particularly aluminum, in the development of dyslipidemia. As per PRISMA guidelines, we did a literature search in four medical databases to give a holistic view of the possible link between aluminum exposure and various biochemical events leading to dyslipidemia.
Context: Respiratory exposure to welding fumes directly or indirectly, in the long run, can lead to systematic effects among welders.
Aims: This study aimed to investigate respiratory symptoms and pulmonary function parameters among welders working in the automotive industry.
Material and methods: This cross-sectional study was performed among 2304 workers from two groups in the manufacturing and administrative staff (as exposure and control groups). Pulmonary function parameters and respiratory symptoms were collected through periodic spirometry examinations and a standard respiratory symptoms questionnaire. Exposure to welding fumes was obtained from the annual measurement data based on the NIOSH7300 method. Data were analyzed using SPSS software version 22 and linear and multiple regression statistical tests.
Results: The mean age of the subjects in the case and control groups were 37.5 and 38.5 years, respectively. All the apparent symptoms of respiratory diseases (cough, sputum) in the welder's group were more than in the control group. Also, there was a significant difference between the respiratory symptoms in the two groups (P < 0.001). The mean value of all spirometric parameters (FVC, FEV1, FEV1/FVC, FEF25-75, PEF) in the case group (welders) was significantly lower than the control group.
Conclusion: The results of this study revealed that the variables of age and work experience effectively reduce all spirometric parameters of welders. Also, regarding the effect of metal vapors, a significant relationship has been seen between Cu in welding fume and FEF25-75 and FEV1 spirometric parameters.
Introduction: Sickness presenteeism is a phenomenon where "workers go to work when ill." The objective of this study was to determine the prevalence of and work-related factors associated with presenteeism among nursing care providers in selected tertiary hospitals in Bangalore city.
Methodology: Participants were selected using stratified sampling followed by simple random sampling. A questionnaire was designed to capture socio-demographic information, sickness-related behavior, performance-based self-esteem (PBSE), and selected work-related characteristics.
Results: A total of 357 participants were enrolled in the study, 274 were staff nurses (S/N) and 83 were nursing assistants (N/A). About 75% of the participants reported presenteeism at least once in the last year, two-fifths did so in the last 4 weeks and nearly 15% were sick on the day of the interview. The mean Stanford Sickness Presenteeism Scale-6 score was 18.49 ± 3.84. The most frequent reason for presenteeism was "perceived mildness of the disease." In bivariate analysis, those who were younger, male, had children, higher qualifications, chronic ailment/s, financial commitments, lesser work experience, and higher PBSE had higher presenteeism scores. When introduced into a linear regression model, those S/N who had children [Standardized coefficient = 0.23 (0.40-1.97)], higher PBSE scores [Standardized coefficient = 0.385 (0.15-2.55)], and reported sickness absenteeism in the preceding 4 weeks [Standardized coefficient = 0.136 (0.12-1.01)] were significantly associated with higher presenteeism scores. Those N/A who had lesser work experience had higher presenteeism scores [Standardized coefficient = -0.33 (-0.02--0.004)].
Conclusion: Presenteeism is a common phenomenon among nursing care providers. It is imperative that both employers and employees be educated about its ill effects on the individual, fellow staff, and patients, followed by the adoption of preventive measures.
Background: Avian diseases should be known to people who raise birds as pets or for commercial purposes. Exposure to high levels of airborne dust and endotoxins is known to cause allergies. This study, therefore, intends to assess avian allergy and its associated factors among poultry workers and bird fanciers in urban Mysuru.
Methods: A cross-sectional study was done over three months among 60 poultry workers and 60 bird fanciers in a selected rural population of the Mysuru district. The participants were selected by simple random sampling method and their data were obtained by interview method using a pre-tested semi-structured questionnaire. Chi-square test/Fisher's exact test was used to check the associations between the demographic variables' avian allergy.
Results: The survey revealed that 31.67% of poultry workers and 53.33% of bird fanciers had symptoms. The majority of the study participants were illiterate and were not using personal protective equipment (PPE) regularly. The results showed a significant association between education (P = 0.013) and the use of PPE (P = 0.020) with avian allergy. Observing the health hazards, 42.10% had respiratory problems, 42.10% had skin problems, and 26.31% had eye problems. Further, a significant association was also found between education and knowledge about diseases (P = 0.001).
Conclusion: The avian allergy among the bird fanciers was higher when compared to poultry workers. It is necessary to organize routine counseling, awareness, and training programs about diseases and prevention strategies related to their work and living environments and keep them updated.
