![Pediatrics, Endocrinology
Transient hypothyroxinemia, a common finding in premature
infants, is not thought to have long-term consequences or
to require treatment. A study was performed to investigate
whether hypothyroxinemia in premature infants is a cause of
subsequent motor and cognitive abnormalities [16]. Blood
thyroxine values were obtained on routine screening in the
first week of life from 536 infants who weighed 2000 g or
less at birth and were born at 33 weeks gestation or earlier.
The data in Table 11.21 were presented concerning the
relationship between mean thyroxine level and gestational
age.
