Abstract: Introduction: Sri Lanka, a middle-income country in South Asia, has seen a rapid expansion in motor vehicles and, associated with this, an increase in demand for fuel. The dispensing of fuel at fuel stations is performed manually by male fuel handlers, who have long working hours. Such workers are exposed to hydrocarbon fuels which are associated with multiple health effects. This study was performed to determine cardiovascular autonomic functions among fuel handlers in a densely populated district of Sri Lanka. Methods: Fuel handlers (n = 50) from the Gampaha district of Sri Lanka, aged between 19 and 65 years, were identified for the study from seven selected fuel stations. Age and gender-matched controls (n = 46) without occupational exposure to fuel were used as controls. All participants were male (females were not employed as fuel handlers). After obtaining written informed consent, demographic data were collected, and general physical examination performed before autonomic function assessment. Non-parametric methods were used for data analysis. Ethical approval was granted by the ethics review committee of the Faculty of Medicine, University of Kelaniya, Sri Lanka. Results: There were no significant differences in weight, height or BMI among the study and the control populations (p[0.05). Both the systolic (SBP) and diastolic (DBP) blood pressures were significantly higher among the fuel handlers compared to controls (SBP, Mann Whitney U = 743.5, p = 0.003) and (DBP, Mann Whitney U = 686.5, p = 0.001). Valsalva ratio was significantly higher among the fuel handlers (Mann Whitney U—874.00, p = 0.043). The rise in DBP during sustained handgrip, a sympathetic parameter, was significantly higher among the controls (Mann Whitney U = 863.00, p = 0.049). Conclusions: Altered sympathetic:parasympathetic balance was observed among the fuel handlers. Monitoring of the health, using personal protective equipment, and curtailing hours of employment per week is recommended for those employed at fuel stations.
