The study complements our previous work that identified fetal head growth trajectories associated with different developmental, behavioural, visual and growth outcomes at 2 years of age. In simple terms: the growth of babies’ bodies and brain track separately and early - while still within the womb’. The finding of an association with maternal lipid metabolism early in pregnancy also provides unique insights into how the mother’s health and diet influence her child’s adiposity’. Very importantly, in both studies, the same critical time period close to the 5th month of pregnancy is the starting point for accelerated or decelerated fetal growth that is sustained into early childhood.
