Objectifs : Étudier les altérations de la thyroïde chez les travailleurs de la santé en fonction de leur statut professionnel. Méthodes : Nous avons réalisé une étude rétrospective incluant 299 employeurs hospitaliers qui ont subi en 2016 un contrôle périodique de surveillance de la santé au Service de la médecine du travail. Selon le statut de travail (travail de nuit en rotation [n° 160] vs travail de jour [n° 139]), nous avons divisé les caractéristiques cliniques, anthropométriques et échographiques de la thyroïde des participants.

Objectives: To study thyroid alterations in health care workers according to their working status. Methods: We performed a retrospective study including 299 hospital employers who underwent in 2016 a periodic health surveillance checks in the Service of Occupational Medicine. According to the working status (rotating night-shift working [no. 160] vs day-working [no. 139]), we divided participant’s clinical, anthropometric, and thyroid echographic characteristics. Results: Respect to day workers, rotating night-shift workers were slightly older and more frequently male whereas had similar thyroid stimulating hormone, Ft3, Ft4 levels, and autoimmunity (anti-TPO levels more than 30). Univariate and multivariate regression analysis revealed that rotating night shift work is associated to a significantly increased number of thyroid nodules. Conclusions: This retrospective report suggests that the alteration in the molecular clocks typical of rotating night-shift workers harbors a higher risk of thyroid nodule development compared with diurnal workers. This novel result deserves replication in larger cohorts since thyroid nodules not rarely can represent thyroid cancers.
