Bus Drivers (bus + drivers)
Selected AbstractsPrevalence of snoring and sleep-disordered breathing in a group of commercial bus drivers in Hong KongINTERNAL MEDICINE JOURNAL, Issue 4 2002D. S. C. Hui Abstract Objectives:,To assess the prevalence of sleep-disordered breathing (SDB) and its associated symptoms in a group of commercial bus drivers in Hong Kong. Methods:,Two hundred and sixteen of 410 bus drivers from three different shifts were interviewed with the Sleep & Health Questionnaire (SHQ) and the Epworth sleepiness scale (ESS) at a Hong Kong bus depot. Seventeen subjects from each shift were then randomly selected for at-home sleep study using the Mesam IV device (Madaus Medizin,Elektronik, Freiburg, Germany). Results:,There were 207 men and nine women (mean age 42.4 ± 7.5 years; body mass index (BMI) 25.4 ± 4.5 kg/m2; ESS 5.3 ± 4.2). From the SHQ it was discovered that: (i) daytime sleepiness was reported by 87 subjects (40%), (ii) snoring , 3 times per week was reported by 80 subjects (37%), (iii) witnessed apnoea was reported by 17 subjects (7.9%) and (iv) 29 subjects (13.4%) reported having fallen asleep during driving. Among the 51 subjects who underwent the at-home sleep study: (i) 31 subjects (61%) had respiratory disturbance index (RDI) , 5 per hour of sleep, (ii) 21 subjects (41%) had RDI , 10 per hour of sleep, (iii) 12 subjects (24%) had RDI , 15 per hour of sleep and (iv) 35 subjects (68.6%) snored objectively , 10% of the night. Ten subjects (20%) had RDI , 5 and sleepiness at work, while five subjects (9.8%) had RDI , 5 and ESS > 10. No significant differences were noted in the SHQ responses, ESS, objective snoring or RDI among the three groups. Multiple regression analysis showed that BMI and witnessed apnoea were the only positive independent predictors of RDI. Conclusions:,This study showed a high prevalence of objective snoring and SDB in a group of commercial bus drivers. Neither self-reported sleepiness nor the ESS could identify subjects with SDB.

Chu Abstract An Erratum has been published for this article in Journal of Multi-Criteria Decision Analysis 10(5) 2001, 285. This paper proposes a model for the generation of daily work duties of airside crew (being bus drivers) at the Hong Kong International Airport. The results can be adopted as a good crew schedule, in the sense that it is both feasible, satisfying requirements of various work conditions, and ,optimal' in minimizing overtime shifts. It is formulated as a goal programme, specifically designed to cater for the manpower planning issues to handle frequent changes of flight schedules by flexibility in work patterns of driver duties. Illustrative results from an actual case study are given. Copyright © 2001 John Wiley & Sons, Ltd. [source] Cancer morbidity among Danish male urban bus drivers: A historical cohort studyAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 7 2010Anne Petersen MPH Abstract Objective To investigate whether urban bus drivers are at increased risk for cancer. Methods Urban bus drivers in a cohort established in 1978 in the three largest cities of Denmark were followed-up in the Danish Cancer Registry until the end of 2003, and relative risks for cancers were estimated. Results Of 2,037 men included 70% reported in 1978 that they smoked. The standardized incidence ratio (SIR) for cancer in comparison with that of other male residents of the three cities was 1.09 [1.0,1.2]. The excess was due mainly to increased risks for cancers of the bladder (SIR, 1.6; 1.2,2.0) and lung (1.2; 1.0,1.4). In an analysis with internal comparisons and adjustment for smoking, we found no significant associations between duration of employment and increased risks for cancers at these two sites. Conclusions In this long-term follow-up study we found little evidence of a causal association between employment as an urban bus driver in Denmark and subsequent cancer. Am. J. Ind.

[source] Nonfatal work-related motor vehicle injuries treated in emergency departments in the United States, 1998,2002AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 9 2009Guang X. Chen MD Abstract Background Current data on nonfatal work-related motor vehicle injuries are limited and fragmented, often excluding government workers, self-employed workers, and workers on small farms. This study seeks to bridge the present data gap by providing a national profile of nonfatal work-related motor vehicle injuries across all industries and occupations. Methods Study subjects were people who suffered nonfatal work-related motor vehicle injuries and were treated in a hospital emergency department in the United States. Subjects were identified from a stratified probability sample of emergency departments. National estimates and rates were computed. Results From 1998 to 2002, the average annual rate of nonfatal work-related motor vehicle injuries was 7 injuries per 10,000 full-time equivalents. The rate was three times higher in men than in women. The rates were higher in workers 15,19 years of age and in workers 70 years or older. Justice, public order, and safety workers had the largest number of injuries, and taxicab service employees had the highest injury rate of all industries. Truck drivers had the largest number of injuries, and police and detectives, public service employees had the highest injury rate of all occupations. Conclusion Future efforts need to develop and enhance the use of surveillance information at the federal and state level for work-related nonfatal motor vehicle injuries. Prevention efforts need to address occupational motor vehicle safety for both commercial truck/bus drivers and workers who are not commercial drivers but who drive light motor vehicles on the job.
