A large number of animal experimental data indicate that pre- or early
postnatal malnutrition can have long term negative consequences on we
ight and height, with smaller weight and height in adulthood than pred
icted on genetics basis. Furthermore, according to the Barker's hypoth
esis, based on data available from British cohort studies, in utero ma
lnutrition could also result in an increased risk of cardiovascular, e
ndocrine and metabolic diseases in adulthood. There are however discor
dant data in the literature which invite to be cautious about on this
hypothesis, mainly because the role of the socio-economic factors duri
ng childhood and adulthood have not been taken into account.
