Calcium and you may Vitamin D Requirements away from Enterally Fed Preterm Children

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 away from Treatments (IOM) put out weight reduction recommendations to have calcium supplements and you can supplement D intakes for everybody age groups. 1 Although not, zero consumption recommendations have been made especially for preterm kids, while they was in fact felt another type of population and failed to complement when you look at the direction having fat loss resource intakes created by the newest IOM. Preterm children have novel bone mineral requirements which can not thought are like those of full-term newborn babies. Past statements in the united states have limited their recommendations so you can full-identity infants. dos , step 3 Although not, The newest Western european Area having Pediatric Gastroenterology, Hepatology, and you can Diet has already described enteral nourishment recommendations for preterm infants. cuatro , 5

Investigation in utero limbs mineralization costs are limited. Cadaver knowledge, beginning with the latest classic performs out-of Widdowson et al, six essentially service an out in utero accretion off calcium during the 3rd trimester away from one hundred to 130 mg/kilogram per day, peaking ranging from thirty two and you will thirty-six weeks’ pregnancy. Phosphorus accretion is roughly 50 % of the newest accretion out-of calcium supplements throughout pregnancy. Surprisingly, more recent reevaluation ones studies by using modern human body structure procedure eight provided beliefs just like the individuals created 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 the maternal concentration. 8 A substantial proportion of pregnant women, especially African American and Hispanic women in the United States and nur katholisches Dating 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 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 1500 g unless there are health issues severely limiting enteral nutrition.
