Ms. Fewtrell et al., RANDOMIZED TRIAL OF HIGH NUTRIENT DENSITY FORMULA VERSUS STANDARD FORMULA IN CHRONIC LUNG-DISEASE, Acta paediatrica, 86(6), 1997, pp. 577-582
To test the hypothesis that the nutrient intake and growth of infants
with chronic lung disease would be improved by providing nutrients in
more concentrated form, and that the lower volume would improve respir
atory status, 60 preterm infants requiring supplemental oxygen at 28 d
ays of age were randomly assigned a low-density (24 kcal/oz) formula f
ed at 180 ml/kg/day, or a high-density (30 kcal/oz) formula at 145 ml/
kg/day. There was no difference in growth, respiratory outcome, oedema
or diuretic requirement between dietary groups. Infants fed the high
nutrient density formula had significantly greater total energy (143 v
s 134 kcal/kg/day) and protein (3.9 vs 3.6 g/kg/day) intakes, largely
because the low-density formula group did not achieve the designated 1
80 ml/kg/day. In conclusion, use of a high-density formula in infants
with chronic lung disease did not improve growth or respiratory outcom
e, despite a small increase in total energy and protein intake.
