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)
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)
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 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)
OBJECTIVE We have studied cross-shift respiratory responses of several individual bioaerosol components of the dust in the grain and feed industry in Norway. METHODS Cross-shift changes in lung function and nasal congestion, as well as in respiratory and systemic symptoms of 56 exposed workers and 36 referents, were recorded on the same day as full-shift(More)
We hypothesised that exposure to workplace aerosols may lead to lung function impairment among cement production workers.Our study included 4966 workers in 24 cement production plants. Based on 6111 thoracic aerosol samples and information from questionnaires we estimated arithmetic mean exposure levels by plant and job type. Dynamic lung volumes were(More)
OBJECTIVE The aim of this study was to analyse longitudinal data to assess the risk of noise-induced hearing loss (NIHL) in Norwegian railway workers. DESIGN Longitudinal. SETTING A major Norwegian railway company. METHODS We examined data from the first and last audiograms for the period 1991-2014, from 9640 railway workers with varying occupational(More)
