Bone health is a critical concern in managing preterm infants. Key nutrients of importance are calcium, vitamin D, and phosphorus. Although human milk is critical for the health of preterm infants, it is low in these nutrients relative to the needs of the infants during growth. Strategies should be in place to fortify human milk for preterm infants with birth weight <1800 to 2000 g and to ensure adequate mineral intake during hospitalization and after hospital discharge. Biochemical monitoring of very low birth weight infants should be performed during their hospitalization. Vitamin D should be provided at 200 to 400 IU/day both during hospitalization and after discharge from the hospital. Infants with radiologic evidence of rickets should have efforts made to maximize calcium and phosphorus intake by using available commercial products and, if needed, direct supplementation with these minerals.

In 2011, the Institute regarding Treatments (IOM) put-out weightloss recommendations to possess calcium supplements and you may vitamin D consumption for all a long time. 1 But not, no consumption advice were made particularly for preterm kids, while they was in fact thought an alternate inhabitants and you can didn’t complement within the assistance getting dieting source intakes created by the brand new IOM. Preterm children has novel limbs mineral requirements that never be presumed becoming exactly like that from full-name infant infants. Past statements in the united states have limited its advice so you can full-identity babies. 2 , step three However, Brand new European Society having Pediatric Gastroenterology, Hepatology, and Nutrients has already explained enteral diet ideas for preterm infants. cuatro , 5

Calcium supplements and you will Vitamin D Requirements of Enterally Fed Preterm Children

Research on in utero bone mineralization pricing try limited. Cadaver training, you start with the fresh vintage functions regarding Widdowson mais aussi al, six basically support an out in utero accretion away from calcium supplements in the 3rd trimester out-of 100 so you’re able to 130 milligrams/kg every single day, peaking anywhere between thirty-two and 36 weeks’ gestation. Phosphorus accretion is roughly half the fresh accretion regarding calcium supplements while in the gestation. Remarkably, more recent reevaluation of them studies by using modern body composition techniques eight provided viewpoints similar to those individuals created by Widdowson et al. 6

In full-term infants, there is a strong correlation between maternal and infant cord blood 25-hydroxyvitamin D (25-OH-D) concentrations, although the cord blood concentration is less than the maternal concentration. 8 A substantial proportion of pregnant women, especially African American and Hispanic women in the United States and Europe, have 25-OH-D concentrations <20 ng/mL (50 nmol/L), 9 a value set for the basis of the Recommended Dietary Allowance. 1 However, in utero, skeletal mineralization is priin D status, making the clinical significance of 25-OH-D concentrations during pregnancy unclear. 10 , 11

Negative effects of Preterm Beginning for the Mineral Metabolic process

Population-based studies of rickets among preterm infants are lacking; therefore, the frequency is not known or reliably estimated. Approximately 10% to 20% of hospitalized infants with birth weight <1000 g have radiographically defined rickets (metaphyseal changes) despite current nutritional practices. 12 This frequency is much lower than the 50% incidence in this population described before fortification of human milk and the use of preterm high mineral containing formulas were routine. 13 One challenge in identifying the prevalence of rickets is the confusion related to terminology. Rickets is defined by radiographic findings, not by any biochemical findings. Standard radiographic definitions of rickets are used. Poorly defined terms, such as osteopenia or biochemical rickets, are often used in the literature interchangeably with radiographically defined rickets. Rickets is not widely reported in preterm infants with birth weight >1500 g unless there are health issues severely limiting enteral nutrition.
