Preterm yenidoğanlarda gebelik yaşına göre küçük olmak ile tiroid fonksiyon testleri arasındaki ilişki

Purpose: The aim of this study was to evaluate the relationship between thyroid hormone levels and clinical outcomes in preterm, small for gestational age (SGA) infants.
 Materials Methods: premature newborns (gestational ≤30 weeks) were divided into two groups as SGA non-SGA. Thyroid stimulating (TSH) free thyroxine (fT4) levels, frequency congenital hypothyroidism (CH), demographic characteristics, morbidity mortality rate compared groups.
 Results: A total 430 newborns, 72 group 358 non-SGA included. CH, morbidity, characteristics similar groups. higher (36.1%) than (13.6%). Serum fT4 level lower (1.04±0.30 ng/dl) (1.24±0.33 ng/dl). serum TSH (9.91 ± 5.6 uIU/L) (6.6 5.2 uIU/L).
 Conclusion: dysfunction preterm infants non-SGA, which due transiently high low concentrations. Therefore, function tests should be monitored periodically infants.
