Amaç: Bu çalışmada prematüre infantlarda kemik döngüsü belirteçlerinin seviyesi ölçülerek büyüme, idrar kalsiyumu ve fosforu ile ilişkisine bakıldı. Yöntem: Enteral beslenmesi yaşamın ilk 5 günü içinde başlanmış 39 prematüre infant ile 20 term infant çalışmaya alındı. Premature infantların doğumda ve 4. haftada boy ve kiloları ölçüldü. Kemik döngüsünün belirteçleri için 4. haftada idrar ve kan örnekleri alındı. Bulgular: Serum ß-CrossLaps, idrar deoxypyridinoline, kalsiyum, tübüler fosfat reabsorbsiyonu (TPR) ve TPR/GFR oranı prematüre infantlarda term infantlara göre istatiksel olarak yüksekti (tüm parametreler için p<0.05). Osteocalcin ile doğum kilosu(r=0.306, P=0.05) ve 4. haftadaki vücut ağırlığı arasında (r=0.307, P=0.047) pozitif korelasyon saptanırken, idrar deoxypyridinoline ile doğum kilosu (r=-0.310, P=0.05), kilo alımı (r=-0.625, P=0.001) ve 4. haftadaki vücut ağırlığı(r=-0.387, P=0.015) arasında negatif korelasyon saptandı. İdrar deoxypyridinoline ile TPR'nin korele olduğu gözlendi (r=0.314, P=0.05). Sonuç: Kilo alımı iyi olmayan prematüre infantların osteopeni yönünden risk altında olduğu düşünüldü. TPR ve idrar kalsiyum atılımın ölçümü prematüre osteopenisini saptamada kullanılabilir. Anahtar Kelimeler: Kemik döngüsü, Büyüme, prematürite, İdrar kalsiyumu
