Are professional drivers less sleepy than non-professional drivers?
Objective: It is generally believed that professional drivers can manage quite severe fatigue before routine driving performance is affected. In addition, there are results indicating that professional drivers can adapt to prolonged night shifts and may be able to learn to drive without decreased performance under high levels of sleepiness. However, very little research has been conducted to compare professionals and non-professionals when controlling for time driven and time of day. Method: The aim of this study was to use a driving simulator to investigate whether professional drivers are more...
The Work Organization of Long-Haul Truck Drivers and the Association With Body Mass Index
Objective: The aim of this study was to examine relationships between work organization features of work hours, work schedules, and job stress with body mass indexes (BMIs) of long-haul truck drivers. Methods: Face-to-face survey data were collected first, followed by collection of anthropometric measures including height and weight (n?=?260). Logistic regression (backward stepwise model) was used to identify significant predictors of BMI and to analyze odds ratios. Results: Mean BMI was 33.40?kg/m2, with 64.2% obese (BMI > 30?kg/m2) and 18.4% extreme/morbidly obese (BMI > 40?kg/m2). Working...
Miscarriage Among Flight Attendants
Background: Cosmic radiation and circadian disruption are potential reproductive hazards for flight attendants. Methods: Flight attendants from 3 US airlines in 3 cities were interviewed for pregnancy histories and lifestyle, medical, and occupational covariates. We assessed cosmic radiation and circadian disruption from company records of 2 million individual flights. Using Cox regression models, we compared respondents (1) by levels of flight exposures and (2) to teachers from the same cities, to evaluate whether these exposures were associated with miscarriage. Results: Of 2654 women interviewed...
Pilot fatigue
Relationships with departure and arrival times, flight duration, and direction INTRODUCTION: Flight timing is expected to influence pilot fatigue because it determines the part of the circadian body clock cycle that is traversed during a flight. However the effects of flight timing are not well-characterized because field studies typically focus on specific flights with a limited range of departure times and have small sample sizes. The present project combined data from four studies, including 13 long-range and ultra-long range out-and-back trips across a range of departure and arrival times ...
The effect of external non-driving factors, payment type and waiting and queuing on fatigue in long distance trucking
INTRODUCTION : The aim of this study was to explore the effects of external influences on long distance trucking, in particular, incentive-based remuneration systems and the need to wait or queue to load or unload on driver experiences of fatigue. METHODS : Long distance truck drivers (n=475) were recruited at truck rest stops on the major transport corridors within New South Wales, Australia and asked to complete a survey by self-administration or interview. The survey covered demographics, usual working arrangements, details of the last trip and safety outcomes including fatigue experiences....
The Effects of Commuting on Pilot Fatigue
Nearly everyone experiences fatigue, but some professions--such as aviation, medicine and the military--demand alert, precise, rapid, and well-informed decision making and communication with little margin for error. The potential for fatigue to negatively affect human performance is well established. Concern about this potential in the aviation context extends back decades, with both airlines and pilots agreeing that fatigue is a safety concern. A more recent consideration is whether and how pilot commuting, conducted in a pilot's off-duty time, may affect fatigue during flight duty. Source...
Assessing sleepiness and sleep disorders in Australian long-distance commercial vehicle drivers
Self-report versus an "at home" monitoring device STUDY OBJECTIVES: As obstructive sleep apnea (OSA) is associated with a higher risk of motor vehicle crashes, there is increasing regulatory interest in the identification of commercial motor vehicle (CMV) drivers with this condition. This study aimed to determine the relationship between subjective versus objective assessment of OSA in CMV drivers. DESIGN: Cross-sectional survey. SETTINGS: Heavy vehicle truck stops located across the road network of 2 large Australian states. PARTICIPANTS: A random sample of long distance commercial vehicle...
ACOEM Releases Guidance on Managing Workplace Fatigue
A workplace in which hazards are well-controlled, with an active culture of health and a supportive work environment, can enhance worker health and well-being, both on and off the job. Implementing a comprehensive fatigue risk management system could improve workplace safety and efficiency, according to a new guidance paper released by the American College of Occupational and Environmental Medicine. Safety and productivity in the workplace are directly related to worker health, reports the paper, titled, “Fatigue Risk Management in the Workplace.” A workplace may have chemical, physical...
Activités, expérience et santé à l’épreuve des évolutions du travail : recherches dans quatre secteurs professionnels
Ce rapport de recherche présente les exposés et débats de l’édition 2007 du séminaire « Ages et travail » organisé par le Créapt. Le thème retenu en 2007 était :« Activités, expérience et santé à l’épreuve des évolutions du travail : recherches dans quatre secteurs professionnels ». Ces quatre secteurs sont la santé, le transport ferroviaire, la métallurgie et l’agriculture. http://www.cee-recherche.fr/fr/rapports/51-activites_experience_sante_travail_secteurs_professionnels_age...
