Little is known regarding the overall prevalence of syncope in a population of workers and the risk of occurrence during working time.
A total of 452 consecutive workers (mean age: 46 ± 9 years) were invited to answer an anonymous questionnaire. They had been employed for 22 ± 10 years for a total of 9765 years worked. In the cohort, 160 subjects (35%) reported a total of 465 episodes of syncope during their lives; 64 (14%) suffered a syncopal episode after the start of employment, but only 26 (5.7%) reported syncope at work, 7 (1.5%) having had 2 episodes, and 1 (0.2%) 3 episodes (total: 36 episodes). The risk of syncope during work was 4.6 times higher for those who had a prior history of syncope [18 of 138 (13%)] than for those who did not [8 of 314 (3%), P = 0.001]. The occurrence of syncope during work for the patients with a history of syncope was one syncopal episode in every 99 years worked and for those who had already had an episode during work, one episode in every 16 years worked. Only one patient experienced minor trauma as a consequence of syncope during work and three were referred to the emergency department. All patients continued their employment without any problems.
The prevalence of syncope during work is low and its impact is benign. The probability of syncope during work is higher for subjects with a history of syncope.
对于工人人群中晕厥的总体患病率以及工作期间发生晕厥的风险，我们知之甚少。
共邀请了 452 名连续工人（平均年龄：46 ± 9 岁）回答匿名问卷。他们的工作年限为 22 ± 10 年，总计工作 9765 年。在该队列中，160 名受试者（35%）报告了一生中总共发生了 465 次晕厥事件；64 名（14%）在开始工作后发生了晕厥事件，但只有 26 名（5.7%）报告在工作时发生晕厥，7 名（1.5%）发生过 2 次晕厥，1 名（0.2%）发生过 3 次晕厥（总计：36 次晕厥）。与没有晕厥病史的人相比（314 人中 8 人，3%），有晕厥病史的人在工作期间发生晕厥的风险高 4.6 倍（138 人中 18 人，13%）。有晕厥病史的患者在工作中发生晕厥的频率为每工作 99 年发生 1 次晕厥，而那些已经在工作中发生过晕厥的患者，每工作 16 年发生 1 次晕厥。只有 1 名患者因工作时晕厥而遭受轻微创伤，有 3 名患者被送往急诊室。所有患者继续就业，没有任何问题。
工作期间晕厥的发生率较低，其影响是良性的。有晕厥病史的患者在工作期间发生晕厥的可能性更高。
