Growth and bone mineralization in small‐for‐gestational‐age preterm infants

Abstract: Bodyweight at term-adjusted age, rather than intrauterine growth, may affect postnatal bone mineralization in preterm low-birthweight infants. Therefore, promoting an increase in body size might increase postnatal bone mineralization in preterm SGA infants.

“…In children born SGA with short stature, low muscle mass may be associated with changes in bone geometry; as assessed by peripheral quantitated computed tomography (pQCT), total bone area, cortical area, cortical thickness, strength-strain index and muscle area were significantly lower than normal references, suggesting impaired bone strength [81]. Impaired bone mineralization has been reported in one study (n = 18) [82] and higher bone strength in another study (n = 31) [83] of SGA infants, in particular those born preterm. Lower bone accretion in preterm infants born SGA than in infants born AGA, independent of body size, suggest that prenatal conditions for bone accretion may not be replicated postnatally [84].…”

“…In term infants, collagen type I synthesis markers are associated with growth during infancy, 6 childhood and adolescence. [7][8][9][10][11][12] In preterm infants, growth, which may also affect bone accretion, 13 is reflected by increased formation and decreased degradation markers of collagen type I until term age (i.e. 40 weeks postmenstrual age).…”

“…SGA ve AGA gruplarda tibial SOS değerleri karşılaştırıldı, sırasıyla birinci SGA ve AGA grupların seri SOS değerleri SGA gestasyon haftasına göre düşük doğum ağırlıklı, AGA gestasyon haftasına göre normal doğum ağırlıklı. SGA ve AGA grupların birinci, üçüncü ve altıncı hafta tibial SOS değerleri karşılaştırıldığında p değerleri sırasıyla; p = 0.09, p = 0.57, p = 0.38.TARTIŞMAÇalışmamızda postnatal birinci, üçüncü ve altıncı hafta tibial SOS değerleri SGA ve AGA preterm yenidoğanlarda farklı bulunmadı.Foton absorbsiyometre yada DEXA kullananılarak kemik durumunun kıyaslandığı çalışmalarda hem term hem preterm AGA yenidoğanlarla kıyaslandığında SGA yenidoğanların daha düşük yada benzer kemik mineral içeriği yada dansitesine sahip olduğu raporlanmıştır (11)(12)(13)(14). SGA infantlarda kemik mineral içeriğinin azalmasının nedeni, diyafizel çapta azalma ve medüller çapta artmadan dolayı kortikal kemik kitlesinde azalma(20), kemik matriks döngüsünde artma, kemik formasyonunda azalma (21) yada minerallerin transplasental geçişinde azalma (22) olarak gösterilmiştir.…”
