Determinants of Infant Adiposity across the First 6 Months of Life: Evidence from the Baby-bod study

Excess adiposity in infancy may predispose individuals to obesity later life. The literature on determinants of infants is equivocal. In this longitudinal cohort study, we investigated pre-pregnancy, prenatal and postnatal different indices infants, i.e., fat mass (FM), percent FM (%FM), index (FMI) log-log (FM/FFMp), from birth 6 months, using linear mixed-effects regression. Body composition was measured 322, 174 109 at 3 months afterwards, respectively, utilising air displacement plethysmography. Positive associations were observed between gestation length infant FM, maternal self-reported pre-pregnancy body %FM, parity %FM FMI birth. Surprisingly, intake iron supplements during pregnancy associated with FM/FFMp months. Male sex formula feeding negatively all conclusion, factors influence early life, any unfavourable impacts be modulated postnatally via practices. Moreover, as these are dependent the used, it crucial that researchers use conceptually statistically robust approaches such FM/FFMp.
