Abstract

Fuel dispensing at fuel stations is performed manually by unprotected male gas station attendants in Sri Lanka, who have long working hours. These workers are exposed to hydrocarbon fuels associated with multiple health effects by modulation of the autonomic nervous system. This study was performed to determine cardiovascular autonomic functions among fuel pump attendants in Sri Lanka. Fuel pump attendants (n = 50) aged between 19 and 65 years were identified for the study from seven fuel stations. They were compared with age- and gender-matched controls (n = 46) without occupational exposure to fuel. A physical examination was performed before the autonomic function and heart rate variability (HRV) assessment. There were no significant differences in weight, height, or BMI between the study and the control populations (p > 0.05). Both the systolic blood pressure (SBP) (Mann Whitney U (MWU) = 743.5, p = 0.003) and diastolic blood pressure (DBP) (MWU = 686.5, p = 0.001) were significantly higher among the gas station attendants compared to controls. Valsalva ratio was significantly higher among the study group (MW U = 874.00, p = 0.043) compared to controls. The HRV analysis showed significantly higher SDNN and SD2 (MWU = 842.00, p = 0.034, and MWU = 843.50, p = 0.035 respectively) among the gas station attendants compared to controls. The changes to the cardiovascular autonomic parameters among those exposed to fuel vapor as a gas station attendant indicate an increase in sympathetic outflow to the vessels. In the occupational setting as fuel pump attendants need periodic monitoring.

探索职业暴露的影响:斯里兰卡男性加油站服务员心血管自律功能研究。
在斯里兰卡,加油站的燃料分配工作由无保护措施的男性加油员手工完成,他们的工作时间很长。这些工人接触的碳氢化合物燃料会通过调节自律神经系统对健康产生多种影响。本研究旨在确定斯里兰卡加油站服务员的心血管自律神经功能。研究从 7 个加油站选取了年龄在 19 岁至 65 岁之间的加油泵服务员(n = 50)。他们与年龄和性别匹配的对照组(n = 46)进行了比较,对照组没有职业性接触燃料的经历。在进行自律神经功能和心率变异性(HRV)评估前进行了身体检查。研究对象与对照组在体重、身高或体重指数方面没有明显差异(P > 0.05)。与对照组相比,加油站服务员的收缩压(SBP)(MWU = 743.5,P = 0.003)和舒张压(DBP)(MWU = 686.5,P = 0.001)均明显升高。与对照组相比,研究组的 Valsalva 比值明显更高(MW U = 874.00,p = 0.043)。心率变异分析表明,与对照组相比,加油站服务员的 SDNN 和 SD2 明显更高(分别为 MWU = 842.00,p = 0.034 和 MWU = 843.50,p = 0.035)。作为加油站服务员而暴露于燃料蒸气的人的心血管自律神经参数的变化表明,流向血管的交感神经外流增加。在职业环境中,作为油泵服务员需要定期进行监测。
