Vibration syndrome symptoms among bus driver’s university in Selangor

The university’s bus drivers have critical roles in being the main transport for students and are occupationally exposed to different environmental stressors. This study aimed to determine the relationship between vibration exposure level with vibration syndrome symptoms among bus drivers’ diversity in Selangor. It seems evident that occupational drivers have an increased risk of developing back pain. Not only are they exposed to whole body vibration, but their work also often includes exposure to several other risk factors for low back pain (LBP), particularly the seated posture (posture). This cross-sectional study was conducted on 65 university bus drivers working in the transportation system at universities in Selangor especially Universiti Teknologi Mara, Cawangan Selangor, Kampus Puncak Alam. The subjects' exposures to whole-body vibration were measured during driving activities. Chi-Square and odd ratios were employed to vibration exposure levels with vibration syndrome symptoms among bus drivers using SPSS version 28.0. The highest exposure levels to whole-body vibration (WBV) among bus drivers are 347.63 ms¹.⁷⁵ , followed by 293.91 ms¹.⁷⁵ and 193.17 ms¹.⁷⁵ . The odd ratio for smoking and non-smoking respondents either back and neck pain or not experiencing back and neck pain are 15.625% and X2 is 12.968 meanwhile the odd ratio for smoking and non-smoking respondents either back and neck pain or not experiencing back and neck pain are 1.429% and X2 is 0.196. Bus drivers who are smoking were easily exposed to whole-body vibration compared to bus drivers who are not smoking. Long exposure will cause low back pain and neck pain to the bus drivers. Due to the limited number of vehicles tested, vehicle variabilities such as vehicle model, the age of the vehicle, and its condition should be evaluated in future WBV exposure studies.
