The objective of the study was to investigate the possible association between maternal/neonatal 25-hydroxy vitamin D (25-OHD) levels and development of necrotizing enterocolitis (NEC).
One hundred and forty-five preterm infants less than or equal to 36 weeks of gestation were enrolled. 25-OHD levels were determined in maternal/neonatal blood samples that were obtained at the time of admission to the neonatal intensive care unit.
Of the 145 enrolled patients, 26 (18%) developed NEC. Maternal/neonatal 25-OHD levels in the NEC group were significantly lower than those of the no-NEC group (P=0.001 and 0.004, respectively). In univariate logistic regression analysis, both maternal/neonatal vitamin D levels were a significant predictor of NEC (odds ratio (OR): 0.92 and 0.89; P<0.001 and P<0.005, respectively). However, multivariate logistic regression analysis revealed that only maternal vitamin D level was a significant predictor of NEC (OR: 0.86, P<0.0009).
This is the first study to propose a possible association between maternal/neonatal 25-OHD levels and subsequent development of NEC in preterm infants.

"Rates were almost three times higher for black populations than for white populations" (Note: blacks hasve lower vitamin D levels
- Part 1. Current Controversies in the Understanding of Necrotizing Enterocolitis Medscape 2003
"The incidence of NEC varies. It is stated most often as 1% to 7% of all neonatal intensive care unit (NICU) admissions, or 1 to 3 per 1,000 live births"
- Costs of necrotizing enterocolitis and cost-effectiveness of exclusively human milk-based products in feeding extremely premature infants Feb 2017
NEC medical + surgical cost = $270,000
- Necrotizing Enterocolitis Risk April 2012
"Necrotizing enterocolitis is a costly disease, accounting for nearly 20% of NICU costs annually."
"Necrotizing enterocolitis survivors requiring surgery often stay in the NICU more than 90 days and are among those most likely to stay more than 6 months"
"Although 90% of infants who develop NEC are born premature, full-term and near-term infants also develop the disease"
"It is estimated that nearly 12% of infants born weighing less than 1500 g will develop NEC; of those, about 30% will not survive."

- 1 in 1,000 live births get NEC (see web above)
- $100,000 = Conservative cost of NEC
thus NEC only adds $100 to the average cost of birth
- 14% less NEC if high good level of vitamin D (study on this page)
Thus adding Vitamin D would only reduce the averagecost of birth due to NEC by $14
This calculation does not consider the decrease in extreme premie births by vitamin D
This calculation does not consider adding Vitamin D to premie after birth but before NEC starts
