Objectives The aim of this study has been to investigate serum activities of liver enzymes in workers exposed to sub-TLV levels of dimethylformamide (DMF). Material and Methods Seventy-two workers and 72 healthy controls participated in the study. All subjects underwent complete physical examinations and abdominal ultrasound examination. Serum aspartate aminotransferase (AST), alanine aminotransferase...
Objectives The aim of the study was to investigate the direct and indirect – mediated by job burnout – effects of job demands on mental and physical health problems. The Job Demands–Resources model was the theoretical framework of the study. Three job demands were taken into account – interpersonal conflicts at work, organizational constraints and workload. Indicators of mental and physical health...
Objectives The research aims to assess the level of physical activity among administrative, technical, and manual workers employed in Warszawa public institutions and to analyze the factors that increase the risk of failing to meet World Health Organization (WHO) recommendations. Material and Methods The study comprised 373 employees of randomly selected institutions. A short version of International...
Objectives This study measures the association between hospital staff’s job strain (JS), mental quality of life (MQL) and how they are influenced by the organization models within emergency and critical care units. Material and Methods This study describes workers employed in emergency departments and intensive care units of a French public hospital. A selfadministered questionnaire was used to survey...
Objectives The aim of the study was to investigate whether a ski helmet interferes with the sound localization and the time of sound perception in the frontal plane. Material and Methods Twenty-three participants (age 30.7±10.2) were tested on the slope in 2 conditions, with and without wearing the ski helmet, by 6 different spatially distributed sound stimuli per each condition. Each of the subjects...
The working environment is the special case of the non-natural environment created by man in which the increased production activity brings about the concentration of stimulators particularly aggressive to the human organism, such as chemical hazards, noise, vibration, extreme temperatures, and finally, intensified psychological and emotional stress. Depending on the nature and intensity, working...
Objectives More and more countries introduce a total ban on smoking tobacco in public places. The aim of this work was to evaluate the effectiveness of “The Act of 8 April 2010 on amendment of the act on protection of health against the consequences of consumption of tobacco and tobacco products and act on National Sanitary Inspectorate” and assess the frequency of complying with the smoking bans...
Objectives Increasing bilateral gluteus medius co-activation has been identified as one of the most important factors in developing low back pain due to prolonged standing in healthy people. This study aims to investigate the impact of an anti-fatigue mat on the bilateral gluteus medius co-activation pattern and to report the low back pain subjectively in 2 different standing positions on the normal...
Objectives Housewives are nucleus of families but as the working, living, and social architecture in the rural areas significantly differ from developed or urban area, the results of urban population cannot be generalized. Hence the purpose of the present study is to evaluate the prevalence of low back pain in non working rural housewives. Also an attempt has been made to determine the impact of social...
Objectives 1-hydroxypyrene is an important biomarker of exposure to polycyclic aromatic hydrocarbons (PAHs), which appears in the urine of exposed human subjects. In developing countries, where advanced instruments are not available, the importance of this biomarker demands convenient and sensitive methods for determination purposes. This study aimed at developing a methodology to quantify 1-hydroxypyrene...
Emergency work can expose personnel to sleep restriction. Inadequate amounts of sleep can negatively affect physiological and psychological stress responses. This review critiqued the emergency service literature (e.g., firefighting, police/law enforcement, defense forces, ambulance/paramedic personnel) that has investigated the effect of sleep restriction on hormonal, inflammatory and psychological...
Introduction The purpose of this study was to develop and initially validate an objective, yet quick, method for assessment of human fatigue. This aim can be achieved by the use of an optical, non-contact method of analysis of pupil activity. The study involved 2 phenomena typical for the behavior of the human pupil: pupillary reflex and pupillary movements. The 1st phenomenon is related to the pupillary...
Introduction Factors such as prolonged sitting at work or improper posture of head during work may have a great role in neck pain occurrence among office employees, particularly among those who work with computers. Although some studies claim a significant difference in head posture between patients and pain-free participants, in literature the forward head posture (FHP) has not always been associated...
Bisphenol A (BPA) is used in the chemical industry as a monomer in the production of plastics. It belongs to a group of compounds that disturb some of the functions of human body, the endocrine system in particular. Extensive use of BPA in manufacturing products that come in contact with food increases the risk of exposure to this compound, mainly through the digestive tract. Literature data indicate...
Objectives The aim of this study is to assess the sleep quality and sleep disorders (prevalence of obstructive sleep apnea and sleepiness) among occupational drivers in Iran and to determine which demographic factors and occupational habits are linked to road traffic accidents. Material and Methods In this analytic cross-sectional study 556 occupational road drivers from Shahroud city (in the northeast...
Objectives The aim of the study was to assess the usefulness of bedside examination for screening of vestibular and balance system for occupational medicine purposes. Study group comprised 165 patients referred to Audiology and Phoniatric Clinic due to vestibular and/or balance problems. Caloric canal paresis of 19% was the cut off value to divide patients into 43 caloric-positive vestibular subjects...
Objectives This study aims to test the validity of the IPD-Work Consortium approach for creating comparable job strain groups between the Job Content Questionnaire (JCQ) and the Demand-Control Questionnaire (DCQ). Material and Methods A random population sample (N = 682) of all middle-aged Malmö males and females was given a questionnaire with the 14-item JCQ and 11-item DCQ for the job control and...
Psychologically and physically straining work conditions increase the risk of low back pain (LBP) development. According to recent recovery theories, leisure time recovery can counteract the negative influences of work stress on health. Similarly, a recent empirical work has indicated a moderating role of recovery on the link between stress and health issues. In this paper, a theoretical model is...
