Amaç: Meslek hastalıkları polikliniğine başvuranlarda tiroid hormon düzeyleri ile işle ilişkili faktörlerin
değerlendirilmesi amaçlanmıştır.
Gereç ve Yöntem: Çalışmaya üniversite hastanesi meslek hastalıkları polikliniğine Kasım 2015- Şubat 2020 tarihleri arasında başvuran 475 çalışan dahil edildi. Çalışanların verilerine; meslek hastalıkları poliklinik muayene formları ve laboratuvar kayıtları retrospektif olarak incelenerek ulaşıldı. Ortalama değerleri karşılaştırmak için Student t testi kullanıldı. İkili analizlerde tiroid stimulan hormon (TSH) değeri ile istatiksel olarak anlamlı ilişkili saptanan bağımsız değişkenler için çoklu lineer regresyon analizi yapıldı.
Bulgular: i475 çalışanın 433'ü (%91,2) erkek ve 173'ü (%36,4) gece vardiyasında çalışıyordu. İşyerinde 293’ü (%61,7) silika tozuna, 23'ü (%4,8) plastik dumana ve 80'i (%16,8) solvente maruz kaldığını ifade etti. 40 yaş üzeri olanlarda (p=0.026), gece vardiyalı çalışanlarda (p=0.023), silika tozuna maruz kalanlarda (p=0.002) daha düşük TSH değerleri; erkek çalışanlarda (p=0.017), 40 yaş altı olanlarda (p=0.042), vücut kitle indeksi (VKİ) 25’den küçük olanlarda (p=0.026) serbest T4 düzeyleri daha yüksek olarak bulundu. Regresyon analizinde VKİ, silika tozu maruziyeti, gece vardiyası çalışması ile azalmış TSH düzeyi arasında anlamlı bir ilişki olduğu görüldü (sırasıyla p=0.033, p=0.028, p=0.045).
Sonuç: Meslek hastalıkları polikliniğine başvuran çalışanlarda gece vardiyalı çalışma ve silika tozuna maruziyetin azalmış TSH seviyeleri ile ilişkili olduğu bulundu. Silika tozu maruziyeti ve gece vardiyalı çalışma önlenebilir risk faktörleri arasında yer almaktadır. Bu nedenle çalışma ortamı yeniden düzenlenmeli, periyodik sağlık muayeneleri yapılmalı, çalışanların iş sağlığı ve güvenliği kurallarına uymaları sağlanmalıdır.

Aim: This study purposed to evaluate thyroid hormone levels and work-related factors in workers.
Materials and Methods: This retrospective study was perfomed at 475 workers who applied to the outpatient clinic of occupational diseases between November 2015-February 2020. Sociodemographic variables, work-related factors and laboratory records were retrospectively evaluated. Student’s t-test was performed to compare mean values. Multiple linear regression analysis was used, including independent variables that were found to be statistically significantly related in binary analysis of thyroid-stimulating hormone (TSH) value.
Results: Of the 475 participants, 433 (91.2%) were male and 173 (36.4%) worked night shifts, 293 (61.7%) were exposed to silica dust, 23 (4.8%) to plastic fumes, and 80 (16.8%) to solvent. Study participants who were over 40 years of age, night shift workers, and workers with exposure to silica dust had significantly lower TSH values (p=0.026, p=0.023, p=0.002, respectively); male workers, workers under 40 years of age, and workers with body mass index (BMI) <25 had significantly higher free T4 levels (p=0.017, p=0.042, p=0.026, respectively). In the regression analysis, it was observed that there was a significant relationship BMI, silica dust exposure, night shift work and low TSH level (p=0.033, p=0.028, p=0.045).
Conclusion: It was found that night shift work and exposure to silica dust were associated with decreased TSH levels in workers. Silica dust exposure and night shift work are among the preventable risk factors. For this reason, the workplace environment should be reorganized, periodic health examinations should be carried out, and workers should be ensured to comply with occupational
health and safety rules.
