Background:We have previously shown that by term age, preterm infants have elevated intrahepatocellular lipid (IHCL) content and altered regional adiposity, both of which are risk factors for cardiometabolic illness in adult life. Preterm nutritional intake is a plausible determinant of these aberrant trajectories of development.Objective:We aimed to establish if macronutritional components of the preterm diet were determinants of IHCL deposition measured at term equivalent age, using (1)H Magnetic Resonance spectroscopy (MRS).Methods:Prospective observational case-control study in a single UK neonatal unit. (1)H MR spectra were acquired from 18 preterm infants (<32 weeks gestational age at birth) at term age and 31 healthy term infants, who acted as a control group. Neonatal nutritional information was collected from birth to 34(+6) weeks postmenstrual age.Results:IHCL (median, interquartile range) was significantly higher in preterm-at-term infants compared with term-born infants: 0.735, 0-1.46 versus 0.138, 0-0.58; P=0.003. In preterm infants, IHCL was positively correlated with lipid intake in the first week of life (r=0.52, P=0.04).Conclusions:This study confirms our previous observation of elevated IHCL in preterm infants at term and suggests that early lipid intake may be a determinant. Future work is warranted to establish the clinical relevance and the role of nutritional intervention in attenuating or exacerbating this effect in preterm infants.International Journal of Obesity advance online publication, 15 January 2013; doi:10.1038/ijo.2012.213. |
