چکیده
زمینه و هدف: آلودگی هوایِ ناشی از ذراتمعلق، بهویژه در مادران باردار میتوانند بر سلامت مادر و جنین اثرات مخربی داشته باشند. از اینرو، هدف این مطالعه بررسی تأثیر ذراتمعلق بر سطح هورمون تحریککنندهی تیروئید در مادران باردار شهر اهواز انجام شد.
مواد و روش ها: دادههای مربوط به مقادیر ذراتمعلق از محصول عمق نوری آئروسل سنجنده مودیس و بهصورت میانگین پنج ساله اول فروردین 1398 تا اسفند 1402 استخراج شد. سطح هورمون تحریککننده تیروئید نیز در 78 مادر غربالشده در سه ماهه سوم بارداری با استفاده از آزمایشهای بیوشیمیایی اندازهگیری و درنهایت رابطه آنها با دادههای ذراتمعلق محل سکونت هر مادر با استفاده از رگرسیون وزنی جغرافیایی مورد پردازش قرار گرفت.
یافتهها: متوسط سطح هورمون تحریک کنندهی تیروئید در افراد مورد مطالعه برابر با 57/6 میلی واحد بر لیتر و در محدوده 30/0 تا حداکثر 3/39 میلی واحد بر لیتر قرار داشت که از محدوده های طبیعی در مادران باردار، بیشتر است. مقادیر عمق نوری آئروسل طی دورهی پنج ساله در محدوده ی 28/0 تا 39/0 و در محل سکونت مادران باردار بیشتر از 30/0 بهدست آمد که آلودگی بالای هوا به ذراتمعلق را نشان داد. نتایج مدل رگرسیون نیز نشان داد که حدود 61 درصد از تغییرات سطوح هورمون تحریک کنندهی تیروئید تحت تأثیر میانگین پنجساله ذراتمعلق اتمسفر بوده است.
نتیجهگیری: غلظت بالای ذراتمعلق در برخی نقاط شهر اهواز میتواند تأثیرات منفی بر سلامت مادران باردار داشته باشد. از اینرو، نظارت مداوم بر کیفیت هوا و ارائه مراقبتهای ویژه در دوران بارداری در این شهر توصیه میشود.

چکیده [English]
Background & Purpose: Air pollution from particulate matter (PM) negatively impacts maternal and fetal health, particularly in pregnant women. This study aimed to evaluate the effects of PM on thyroid-stimulating hormone (TSH) levels in pregnant women residing in Ahvaz.
Materials and Methods: PM data were derived from the aerosol optical depth (AOD) product of the MODIS satellite, covering five years (April 1, 2019–March 21, 2024). Using biochemical assays, TSH levels were measured in 78 pregnant women during their third trimester. The relationship between TSH levels and PM levels specific to each mother’s residence was analyzed using geographically weighted regression (GWR).
Results: The mean TSH level was 6.57 mIU/L (range: 0.3–39.3 mIU/L), exceeding the normal range for pregnant women. AOD values over the five years ranged from 0.28 to 0.39, with levels above 0.30 at the mothers’ residences, indicating high PM pollution. The GWR model revealed that approximately 61% of the variation in TSH levels was attributable to the five-year average PM concentration.
Conclusion: High PM concentrations in parts of Ahvaz pose significant risks to maternal health during pregnancy. Air quality monitoring and specialized care are essential to protect pregnant women in this region.
