Association of Thyroid Function Test Abnormalities and Thyroid Autoimmunity With Preterm Birth

Abstract

Background: The reviewed literature collectively underscores the significant association between thyroid function test abnormalities and thyroid autoimmunity with preterm birth and other adverse pregnancy outcomes. The foundational work by (Balthazar & Z Steiner, 2012) establishes the critical role of thyroid autoimmunity during the periconceptional period, indicating that abnormalities in thyroid function can lead to obstetric complications, including preterm birth. Literature Review: The systematic reviews conducted by (Nazarpour et al., 2015) and (Sullivan, 2016) further elucidate the implications of maternal thyroid dysfunction, particularly emphasizing the increased risks of preterm birth and low birth weight associated with thyroid disorders. These findings are echoed in the work of (J. Blumenthal & J. Eastman, 2017), which correlates elevated thyroid-stimulating hormone (TSH) levels and the presence of thyroid autoantibodies with adverse pregnancy outcomes, reinforcing the necessity for vigilant monitoring of thyroid function in pregnant women. Moreover, the reviews by (C. Dong et al., 2020) highlight the broader implications of maternal thyroid health, including potential long-term neurodevelopmental effects on offspring. These insights are crucial as they emphasize the need for healthcare providers to consider not only immediate pregnancy outcomes but also the potential long-term consequences of maternal thyroid autoimmunity. Conclusion: In conclusion, the literature reviewed presents compelling evidence of the multifaceted relationship between thyroid function abnormalities, thyroid autoimmunity, and adverse pregnancy outcomes, particularly preterm birth. The studies collectively advocate for heightened awareness and monitoring of thyroid health in pregnant women, emphasizing the critical role of thyroid function in ensuring both maternal and fetal well-being.
