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.
