Background and aims Total adiposity doubles in early infancy1, however there exists little data describing the change in adipose tissue (AT) distribution and intrahepatocellular lipid (IHCL) over this period. In adults AT distribution and IHCL have important health implications2. We aimed to measure the change in AT distribution and IHCL in healthy breastfed babies.
Design Healthy, term, appropriate weight for gestational age infants were recruited from the postnatal ward at Chelsea and Westminster Hospital. Magnetic resonance images and proton spectra were acquired after birth and at 2–3 months as previously described3, 4. IHCL results are presented as the ratio CH2/water.
Results We studied 32 infants. Change in AT and IHCL are presented in table 1. While total AT volume doubled, there was variation in the magnitude of change in the different regional AT compartments.
Conclusions Growth of different regional AT depots occurs at different rates, and IHCL increases in early infancy. The physiological significance of these novel findings is uncertain.
