However, only a small number of studies have been conducted in Malaysia. Objective: This paper aims to highlight the prevalence of OSA among truck drivers and express bus drivers in Malaysia and efforts being undertaken to address issues related to OSA among commercial vehicle drivers. Methodology: Two separate studies were conducted: a cross sectional study among truck drivers and secondly among express bus drivers. The screening process for identifying the high risk group for OSA was done using Berlin questionnaire. Meanwhile, among express bus drivers, OSA was confirmed with sleep study using polysomnography test. Result: Screening of risk group of OSA among truck drivers revealed that 14.6% (19) of drivers were categorized as having high risk of OSA while 85.4% (111) having low risk of OSA. While, in another study, polysomnography test among express bus drivers showed that 83 (28.7%) had mild OSA, 26 (9.0%) had AHI moderate OSA, and 19 drivers (6.6%) severe OSA. Conclusion: This paper highlighted the issues of OSA among commercial vehicle drivers in Malaysia. With an alarming high prevalence, OSA should be a major road safety concern in this country. A special study focusing on sleep and fatigue related crashes may need to be conducted to complement the current studies and full implementation of existing efforts and initiatives to address OSA in road crashes should be realized by the relevant authorities.展开更多

The SOCSO （Social Security Organization） reported that the number of deaths due to commuting accidents was 760, nearly two times more than deaths caused by accidents that happened at the workplace （471 deaths）. The aim of this study is to investigate the relationship of socio-demographic background and the risk exposure of the drivers during their work commuting trips. The study was based on compensation claims to SOCSO where data were extracted from ＂Form 21＂ provided by SOCSO. A total of 377 respondents were selected through systematic random sampling method from a list of SOCSO claimants. It was found that majority of the traffic accidents （83%） involved males and most of them （92.2%） were on motorcycles. Male drivers have an average driving experience of 10.7 years and 8.6 years for females. The estimation of the travelled distance for the sample from home to the workplace is 0.65-131 km. Mean accident occurrence time was 23 rain whilst mean distance was 11.6 km. The multiple regression analysis showed that the accident distance was affected by the age of driver, actual travel distance, travel objective and speed.展开更多
