The study included 69 hypothyroid women and 431 euthyroid women as a control group. Maternal thyroid function was measured by measuring thyroid-stimulating hormone (TSH), T3, T4, and anti-thyroid peroxidase (anti-TPO) antibodies. Neonatal outcomes included birth weight, gestational age, RDS, and cord blood TSH.

The newborns of hypothyroid mothers, especially those with subclinical hypothyroidism, were more likely to have RDS, require treatment in the neonatal intensive care unit (NICU), and need advanced ventilatory support. Babies born to hypothyroid mothers had a higher TSH level in the umbilical cord blood. Thyroid dysfunction in mothers was associated with longer hospital stays in the NICU and a higher need for oxygen treatment in babies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Preterm labor and poor neonatal outcomes are associated with maternal hypothyroidism, especially with subclinical levels.
