Using record linkage to investigate perinatal factors and neonatal thyroid-stimulating hormone

Record-linkage is a feasible method for investigating the relationship between perinatal factors, maternal and neonatal thyroid stimulating hormone

Perinatal factors associated with neonatal thyroid-stimulating hormone in normal newborns

PURPOSE This study was to evaluate the effect of neonatal, maternal, and delivery factors on neonatal thyroid-stimulating hormone (TSH) of healthy newborns. METHODS Medical records of 705 healthy infants born through normal vaginal delivery were reviewed. Neonatal TSH levels obtained by neonatal screening tests were analyzed in relation to perinatal factors and any associations with free thyr...

Thyroid Stimulating Hormone Thyroid Stimulating Hormone

Neonatal thyroid function: influence of perinatal factors.

Indices of thyroid function were measured in 229 healthy term neonates at birth and at 5, 10, and 15 days of age. Results were analysed to assess whether maternal diabetes mellitus, toxaemia of pregnancy, intrapartum fetal distress, duration of labour, method of delivery, asphyxia at birth, race, sex, birthweight, birth length, head circumference, or method of feeding influenced any index. Thyr...
