BACKGROUND There is a general perception that train drivers and conductors may be at increased risk of developing noise-induced hearing loss. AIMS To study job-related hearing loss among train drivers and train conductors. METHODS Audiograms from train drivers and train conductors were obtained from the medical records of the occupational health service(More)
Cement dust exposure has previously been associated with airway symptoms and ventilatory impairment. The aim of the present study was to examine lung function and airway symptoms among employees in different jobs and at different levels of exposure to thoracic dust in the cement production industry. At the start of a 4-yr prospective cohort study in 2007,(More)
OBJECTIVES To study possible effects of aerosol exposure on lung function, fractional exhaled nitric oxide (FeNO) and inflammatory markers in blood from Norwegian cement production workers across one work shift (0 to 8 h) and again 32 h after the non-exposed baseline registration. METHODS 95 workers from two cement plants in Norway were included.(More)
BACKGROUND While the health benefits of physical activity are well established, little is known about health effects of physical activity programs initiated by employer. METHODS Background data and level of physical activity were collected by questionnaire among 78 men and 43 women working in road maintenance pre and post an 8-week physical activity(More)
AIMS To analyse longitudinal changes in pulmonary function in professional divers and their relation with cumulative diving exposure. METHODS The study included 87 men at the start of their education as professional divers. At follow up one, three, and six years later, 83, 81, and 77 divers were reexamined. The median number of compressed air dives in the(More)
In this prospective study over twelve years, we have studied 30 young professional divers. The aim of the study was to see if changes in hearing thresholds were related to cumulative diving exposure. The study started at the beginning of the divers' education to become professional divers. Over the follow-up period the divers performed air-dives to shallow(More)
OBJECTIVES The aim of this study was to extensively characterize grain workers' personal exposure during work in Norwegian grain elevators and compound feed mills, to identify differences in exposures between the workplaces and seasons, and to study the correlations between different microbial components. METHODS Samples of airborne dust (n = 166) were(More)
OBJECTIVES Our main aim was to study the long-term neuropsychological effects of non-saturation diving. Further, we aimed to investigate whether neuropsychological performance was predictive of subsequent diving accidents and diving status. METHODS In this prospective longitudinal study, we enrolled 50 male diving students (mean age 25.3 years) at a(More)
OBJECTIVE Railway workers performing maintenance work of trains and tracks could be at risk of developing noise-induced hearing loss, since they are exposed to noise levels of 75-90 dB(A) with peak exposures of 130-140 dB(C). The objective was to make a risk assessment by comparing the hearing thresholds among train and track maintenance workers with a(More)
We investigated the level of pro- and anti-inflammatory biomarkers before and after 8 weeks of unsupervised physical activity (PA) initiated by employer. During autumn 2014, background data, blood samples and self-reported exercise level were collected from 76 men and 41 women in a Norwegian road maintenance company. Monocyte chemoattractant protein-1(More)
