Occupational risk factors for low back pain among drivers of three-wheelers in Sri Lanka.
Approximately 5% of all households in Sri Lanka operate a three-wheeler as their primary source of income. However, very little is known about the occupational health risks associated with driving these vehicles.The aim of this study was to assess occupational risk factors, including the number of hours worked associated with the 4-week prevalence of low back pain (LBP) among drivers of three-wheelers.Questionnaires were administered to 200 full-time drivers of three-wheelers from the Galle District in Sri Lanka. Occupational, psychological, socio-demographic, lifestyle, and anthropometric variables were collected. Univariate and multivariate analysis were used to investigate the correlation between occupational risk factors of the prevalence of LBP.15·5% of respondents reported experiencing LBP in the previous 4 months. Univariate analysis revealed that the number of hours worked per week, feeling pressure to compete with other drivers, and perceived stress scale scores were significantly associated with the 4-week prevalence of LBP. Multivariate analysis found that the number of hours worked per week and engine type were significantly associated with LBP.LBP is common among drivers of three-wheelers in Sri Lanka. Long work hours and two-stroke engines were significantly associated with LBP. Results from this study point towards a role for educational, behavioral health, and policy interventions to help prevent and reduce LBP among these drivers.
