Abstract
The relationship between thyroid function, mode of delivery, and illness in infants 34–36 weeks’ gestation has not been well studied. We hypothesized that infants born by cesarean delivery and those with increased illness would have a reduction in thyroxine (T4) following birth. Total T4 and thyroid-stimulating hormone were obtained at birth (Time 1) and between days 2 and 5 (Time 2). The study sample included 129 infants 34–36 weeks’ gestation. There were no differences in total T4 between infants born by cesarean or vaginal delivery (p=0.18), or between those requiring respiratory support compared to infants not requiring respiratory support (p=0.09). At Time 2, 93% of the study population had a total T4 below one standard error of the reference laboratory mean. In our study sample, despite many infants having a low total T4, there was no association between total T4 levels, respiratory support, or mode of delivery.
