Factors Associated with Metabolic Bone Disease of Prematurity at Vietnam National Children’s Hospital

Abstract: Objective: To determine factors associated with metabolic bone disease of prematurity (MBDP) in preterm infants born before 32 weeks of gestation. Methods: A cross-sectional study was conducted in 118 preterm infants with a gestational age < 32 weeks treated at the Neonatal Center of Vietnam National Children’s Hospital from June 2025 to February 2026. MBDP was defined as serum alkaline phosphatase > 600 IU/L combined with serum phosphate < 1.8 mmol/L. Factors associated with MBDP were analyzed using univariable and multivariable logistic regression. Results: MBDP was identified in 41 of 118 infants (34.7%; 95% CI: 26.8-43.7). Univariable analysis identified associations with lower birth weight, major neonatal morbidities, postnatal corticosteroid and diuretic exposure, blood-product transfusion, and prolonged parenteral nutrition. In multivariable analysis, parenteral nutrition beyond 14 days was the only factor that remained independently associated with MBDP (aOR = 2.86; 95% CI: 1.05-7.74; p = 0.039), whereas postnatal corticosteroid use showed borderline statistical significance (aOR = 2.92; 95% CI: 1.00-8.54; p = 0.050). Conclusion: Parenteral nutrition beyond 14 days was independently associated with MBDP. Preterm infants requiring prolonged parenteral nutrition should therefore be prioritized for monitoring of bone metabolism and optimization of nutritional strategies.
