Insights
Premature infants born before 30 weeks gestation, delayed vitamin D (VitD) supplementation, and late achievement of total enteral nutrition (TEN) are key risk factors for metabolic bone disease (MBD). These findings aid in preventing MBD in vulnerable newborns.
Area of Science:
- Neonatology
- Pediatric Bone Health
- Perinatal Medicine
Background:
- Metabolic bone disease (MBD) of prematurity is a significant concern in neonatal intensive care.
- Identifying risk factors is crucial for timely intervention and prevention strategies.
Purpose of the Study:
- To analyze the risk factors associated with the development of MBD in preterm infants.
- To identify independent predictors for MBD in a cohort of extremely preterm neonates.
Main Methods:
- A case-control study involving 238 preterm infants (<34 weeks gestation) hospitalized for at least 6 weeks.
- Comparison of maternal, parturition, neonatal, and treatment-related factors between infants with MBD (cases) and those without (controls).
- Statistical analysis including t tests, chi-square tests, and logistic regression to determine independent risk factors.
Main Results:
- Infants with MBD had significantly lower gestational age and birth weight.
- Independent risk factors for MBD included birth before 30 weeks gestation, delayed vitamin D (VitD) supplementation (>14 days), and delayed achievement of total enteral nutrition (TEN) (>28 days).
- Other associated factors included small-for-gestational-age status, antenatal corticosteroid use, sedative use, ventilator use, diuretic use, and liver function impairment.
Conclusions:
- Gestational age <30 weeks, delayed VitD supplementation, and delayed TEN are independent risk factors for MBD in preterm infants.
- Early identification and management of these factors are essential for preventing MBD in high-risk neonates.
- This study provides evidence for targeted preventive measures in neonatal care settings.
Abstract:
The present study aims to analyze the risk factors for metabolic bone disease (MBD) of prematurity.A total of 238 preterm infants who were born at <34 weeks of gestation and were hospitalized for at least 6 weeks in the Department of Neonatology, Fujian Maternity and Children Hospital between January 1, 2011 and November 30, 2015 were enrolled in the study. Sixteen preterm infants diagnosed with MBD were selected as the case group, and 32 non-MBD preterm infants were matched 2:1 at admission into the study. The 2 groups were compared to examine the differences in maternal obstetric conditions, conditions during parturition, neonatal conditions, and neonatal diseases and treatments. The risk factors for MBD of prematurity were analyzed using t tests, χ tests, and a logistic regression model.The mean gestational age and birth weight of the case group were significantly lower (P < .05) than those of the control group. Compared with the control group, the case group had a significantly higher ratios of small-for-gestational-age infants, antenatal maternal corticosteroids use, sedative use, ventilator use, aminophylline use, diuretic use, liver function impairment, vitamin D (VitD) supplementation at more than 14 days of age, achievement of total enteral nutrition (TEN) beyond 28 days of age, and feeding intolerance.Logistic regression analysis showed that birth at <30 weeks of gestation, VitD supplementation at >14 days of age, and achievement of TEN beyond 28 days of age were independent risk factors for MBD (P < .05).Level of Evidence: IV.
