HM provided a clear protective effect against NEC , with an approximate 4 % reduction in incidence .
HM also provided a possible reduction in LOS , severe ROP and severe NEC .
Particularly for NEC , any volume of HM is better than EPTF , and the higher the dose the greater the protection .
Evidence regarding pasteurisation is inconclusive , but it appears to have no effect on some outcomes .
Improving the intake of mother ’s own milk ( MOM ) and /or donor HM results in small improvements in morbidity in this population
Early human milk feeding is associated with a lower risk of necrotizing enterocolitis in very low birth weight infants
Background : Necrotizing enterocolitis ( NEC ) is a frequent cause of mortality and morbidity in very low birth weight ( VLBW ) infants .  Human milk ( HM ) feeding has been associated with lower risk of NEC . However , mothers of VLBW infants often experience insufficient milk production , result ing in mixed feedings of HM and formula . Moreover , medical complications often limit the volume of feeding they can be given . Objective : To determine if high proportions of ( 50 % or greater ) HM enteral feeding within the first 14 days of life are protective against NEC . Method : This was a prospect i ve cohort study of VLBW infants who were grouped according to the HM proportion of enteral feeding in the first 14 days : < 50 % ( low human milk , LHM , n=46 ) and ⩾50 % ( high human milk , HHM , n=156 ) . The outcome of interest was development of NEC ( Bell stage 2 or 3 ) . Logistic regression was used to estimate odds ratios ( OR ) and 95 % confidence intervals ( CI ) and to assess potential confounding due to perinatal risk factors . Result : Two hundred and two infants were studied . Confirmed NEC occurred in 5/46 ( 10.6 % ) of the LHM group , as compared with 5/156 ( 3.2 % ) of the HHM . Gestational age was the only perinatal factor associated with risk of NEC . After adjustment for gestational age , HHM was associated with a lower risk of NEC ( ( OR=0.17 , 95 % CI : 0.04 to 0.68 ) , P=0.01 ) . Conclusion : Enteral feeding containing at least 50 % HM in the first 14 days of life was associated with a sixfold decrease in the odds of NEC
