A population based case-control study was performed in Cracow, Poland, to determine the effect of occupational air pollutants on various histological types of lung cancer. Male cases and controls were identified from the Cracow Death Register. Information was obtained by mailed questionnaire from next of kin on smoking, occupational branch, occupational exposures, and other pertinent variables....

BACKGROUND Exposure to electromagnetic field (EMF) emitted by mobile phone and other machineries concerns half the world's population and raises the problem of their impact on human health. The present study aims to explore the effects of electromagnetic field exposures on sleep quality and sleep duration among workers from electric power plant. METHODS A cross-sectional study was conducted i...

the purpose of present research is to consider the relationship between occupational prestige and avoidance variables and intermediate role of organizational indifference. this research is practical and its data were collected through descriptive method and is descriptive-correlative. statistical community is all ilam petrochemical's co employees. about 276 subjects were selected as sample...

The aim of this article is to relate the tradition studies on socio-occupational classes with perspective structural informality. Taking Argentina as a case study, it examines way in which occupational class inequality and job quality condition level welfare employed population. study follows quantitative methodology based Argentina's Permanent Household Survey. Regression models show persisten...

BACKGROUND An individual's occupational activity (OA) may contribute significantly to daily physical activity (PA) and sedentary behavior (SB). However, there is little consensus about which occupational categories involve high OA or low OA, and the majority of categories are unclassifiable with current methods. The purpose of this study was to present population estimates of accelerometer-deri...

Unintentional injuries cause much of the global mortality burden, with the workplace being a common accident setting. Even in high-income economies, occupational injury figures remain remarkably high. Because risk factors for occupational injuries are prone to confounding, the present research takes a comprehensive approach. To better understand the occurrence of occupational injuries, sociodem...

In this introductory article the author argues for an increased use of a multivariate analytical approach to the complex problems encountered in occupational hygiene. Relations between exposure at the work place and reported health effects arc mostly so complicated and depend on so many factors that methods other than the traditional statistical techniques should be applied. Chemometrics is a f...

INTRODUCTION Climate change, air pollution, temperature increase and other environmental variables are modifying air quality, contributing to the increase of prevalence of allergic respiratory diseases. Allergies are complex diseases characterized by multilevel interactions between individual susceptibility, response to immune modulation and environmental exposures to physical, chemical and bio...

OBJECTIVE To explore and describe factors associated with occupational gaps and to identify factors at 3 months that predict occupational gaps one year post-stroke. A gap, a restriction in participation, is considered to be present when there is a discrepancy between what the individual wants to do and what they actually do in everyday life. DESIGN Prospective longitudinal study. SUBJECTS T...
