Thyroid disorders are a frequently encountered issue during pregnancy and a cause of maternal and fetal morbidity. In regions like Appalachia that are particularly susceptible to health disparities, descriptive studies are needed to assist in identifying pathologic derangements. We sought to characterize fetal thyroid hormone levels at delivery and investigate whether or not maternal demographic characteristics affect the prevalence of neonatal thyroid disease. A cross-sectional analysis was conducted on 130 pregnant women recruited from the Tri-State region, incorporating areas of Kentucky, Ohio, and West Virginia. Total triiodothyronine (T3) ( p = 0.4799), free T3 ( p = 0.6323), T3 uptake ( p = 0.0926), total thyroxine (T4) ( p = 0.8316), free T4 ( p = 0.0566), and Thyroid stimulating hormone (TSH) ( p = 0.8745) levels were comparable between urban and rural newborns. We found no effect of hypertension status or nicotine levels on fetal umbilical cord thyroid hormone levels. Maternal diabetic status was associated with lower T4 ( p = 0.0099) and free T4 ( p = 0.0025) levels. Cotinine affected levels of T4 ( p = 0.0339). In regard to maternal Body Mass Index (BMI), there was an increase in total T3 as BMI increased ( p = 0.0367) and no significant difference in free T3, T3 uptake, T4, free T4, or TSH. There was a negative correlation between TSH and 1 min Apgar scores ( p = 0.0058). Lead and cadmium have been implicated to alter TSH levels, but no correlation was found in our study (r 2 = 0.0277). There were no differences in cord blood between urban (37.3 ± 10.3 fmol/ug DNA) and rural (70.5 ± 26.8 fmol/ug DNA) benzo(a)pyrene DNA adducts ( p = 0.174). Thyroid disorders present a unique opportunity for the prevention of perinatal morbidity and mortality, since maternal treatment, as well as maternal demographic characteristics, can have direct fetal effects. |
