Calcium supplements and you can Vitamin D Standards off Enterally Fed Preterm Babies

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 newest Institute out of Treatments (IOM) released fat loss advice to possess calcium and vitamin D intakes for everybody age groups. 1 But not, no intake pointers have been made particularly for preterm babies, because they have been believed another people and you can failed to fit in guidelines to have weight reduction resource intakes produced by the newest IOM. Preterm children have unique bone nutrient conditions which can not be assumed to-be similar to that from complete-term newborn babies. Earlier comments in america don’t have a lot of its guidance so you’re able to full-term kids. 2 , step 3 Although not, The newest European Area to possess Pediatric Gastroenterology, Hepatology, and you can Nutrition has recently described enteral diet recommendations for preterm infants. 4 , 5

Data on in utero limbs mineralization costs is actually minimal. Cadaver education, beginning with the newest vintage works out of Widdowson ainsi que al, 6 generally help a call at utero accretion of calcium supplements into the third trimester away from one hundred so you’re able to 130 mg/kilogram every single day, peaking between 32 and you will 36 weeks’ pregnancy. Phosphorus accretion is roughly 1 / 2 of this new accretion out-of calcium while in the pregnancy. Surprisingly, new reevaluation of those research that with progressive human body constitution processes seven provided viewpoints exactly like men and women developed by Widdowson et al. six

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 incontri tardone online 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

Outcomes of Preterm Birth on Nutrient Metabolism

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.
