Introduction: Headache attacks may be triggered by several factors, among them odors, especially in migraine patients. Objectives: The aim of this study wasto determine the association between gasoline odor and headache attacks in patients with migraine or tension-type headache (TTH). Subjects and Methods: The study was prospective, cross-sectional, with comparison of groups, using nonrandom sample and convenience. Fifty-two gas station workers diagnosed with migraine or TTH according to ICHD-3 criteria were interviewed on the relationship between gasoline odor and headache. Results: Of the 52 gas station workers with headaches, there were 39 (75%) with migraine without aura and 13 (25%) with TTH. The age ranged from 19 to 50 years, with a mean of 29.5 ± 7.2 years. Osmophobia during headache attacks predominated in workers with migraine (29/39; 74.4%). The onset of headache due to odor exposure occurred in 23/39 (60%) of the workers with migraine and in 2/13 (15.4%) in TTH. These differences were statistically significant (χ2 = 7.4; p = 0.016). Osmophobia in the absence of pain (period between attacks) predominated in workers with migraine (17/39, 43.6%), but with no statistical value. Conclusions: Gas station workers diagnosed with migraine or TTH may experience osmophobia and headache triggered by the odor of gasoline.

接触汽油气味的加油站工作人员的头痛和呼吸恐惧症

介绍：头痛发作可能由多种因素引发，其中包括气味，尤其是偏头痛患者。目的：本研究的目的是确定偏头痛或紧张型头痛 (TTH) 患者的汽油气味与头痛发作之间的关联。对象和方法：该研究是前瞻性的、横断面的、组间比较、使用非随机样本和方便。52 名根据 ICHD-3 标准诊断为偏头痛或 TTH 的加油站工作人员就汽油气味与头痛之间的关系进行了访谈。结果：52名出现头痛的加油站工作人员中，39名（75%）无先兆偏头痛，13名（25%）TTH。年龄19～50岁，平均29.5±7.2岁。头痛发作期间的渗透恐惧症在偏头痛工人中占主导地位 (29/39; 74. 4%）。23/39 (60%) 的偏头痛工人和 2/13 (15.4%) 的 TTH 工人因气味暴露而头痛发作。这些差异具有统计学意义（χ2 = 7.4；p = 0.016）。没有疼痛（发作间隔期）的渗透恐惧症在偏头痛工人中占主导地位（17/39，43.6%），但没有统计价值。结论：被诊断为偏头痛或 TTH 的加油站工作人员可能会经历由汽油气味引发的渗透恐惧症和头痛。
