Mean (SD) for the 25 mother-infant pairs included in this study. a Significance assessed with paired t-tests between 1 and 6 months; b Lean mass reflects fat-free mass minus BMC (lean tissue only, excluding bone mass); c Adiposity calculated as percent of fat mass (g) to total mass (g). SD, standard deviation; BMI, body mass index; F/M, females/male; BMC, bone mineral content; BMD, bone mineral density. * p < 0.05, ‡ p < 0.001.
