To estimate in a longitudinal study the yearly incidence of carpal tunnel syndrome (CTS) in a cohort of women working as cashiers.
A total of 198 cashiers, belonging to a cohort investigated in 2011-2012 for arm pain, were screened for re-assessment in 2015 (at least 40 months from the first examination), and 156 women had complete demographic, personal and working data allowing to be included in this study. On the basis of self- and clinician-administered questionnaires investigating the presence of CTS, all symptomatic patients underwent clinical and neurophysiological [nerve conduction studies (NCS) of median and ulnar nerves] assessments.
NCS confirmed the presence of CTS in 17 out of 149 workers; however, seven of them already received the diagnosis of CTS at the previous assessment in 2011-2012, leading to an overall incidence of new cases equal to 7.0%. Cumulative working time at the cashier of the women with CTS in the period 2012-2015 was highly variable (1744-4479 h) without an evident association with the severity of CTS. No differences in general demographic data were found in the women with vs. without CTS. Comorbidities potentially associated with increased risk of CTS were present in 21 women in the entire cohort (14.0% of the population, 40.0% in the subgroup of women with newly assessed CTS). Overweight/obesity and hypothyroidism were the most frequent comorbidities.
The results of this prospective study showed that the annualized incidence of CTS in our population of cashier was 2.0%; 40% of the new CTS cases had comorbidities.
通过纵向研究，估算在一组从事收银员工作的女性队列中，腕管综合征（CTS）的年发病率。
共有 198 名收银员，他们属于 2011-2012 年手臂疼痛队列研究的一部分，在 2015 年进行了重新评估（距离第一次检查至少 40 个月），其中 156 名女性有完整的人口统计学、个人和工作数据，可纳入本研究。基于自我和临床医生管理的问卷，调查 CTS 的存在，所有有症状的患者都进行了临床和神经生理学[正中神经和尺神经的神经传导研究（NCS）]评估。
NCS 确认 149 名工人中有 17 人患有 CTS；然而，其中 7 人在 2011-2012 年的上次评估中已经被诊断为 CTS，导致新病例的总发病率为 7.0%。患有 CTS 的女性在 2012-2015 年期间在收银员岗位上的累计工作时间差异很大（1744-4479 小时），与 CTS 的严重程度没有明显关联。在患有 CTS 的女性与未患有 CTS 的女性之间，一般人口统计学数据没有差异。在整个队列中，有 21 名女性存在与 CTS 风险增加相关的合并症（占人群的 14.0%，在新评估的 CTS 女性亚组中占 40.0%）。超重/肥胖和甲状腺功能减退是最常见的合并症。
这项前瞻性研究的结果表明，我们的收银员人群中 CTS 的年化发病率为 2.0%；40%的新 CTS 病例有合并症。
