Gene expression data. Transcript levels in peripheral blood cells of CPT1A, FASN, FTO, INSR, LEPR, MC4R and UCP2 at 5 years in breastfed (BF) or formula-fed (FF) children whose birth weight was appropriate or small for gestational age (AGA or SGA). Results are mean ± SD. Statistical analysis: F: effect of the type of infant feeding; W*F: interactive effects between birth weight and the type of infant feeding (P < 0.05, two-way ANOVA). f represents differences between FF and BF within the same group of birth weight; w represents differences between AGA and SGA within the same group of infant feeding (P˂ 0.05, Student’s t test)
