An increasing number of diseases in child and adult life are now thoug
ht to have their origins in the fetal period. Central to this predispo
sition is restriction of fetal growth. During the period reviewed in t
his article, the associations between adult hypertension and low birth
weight were confirmed, and numerous studies have investigated possible
mechanisms by which the metabolism of an individual may be programmed
by an adverse intrauterine environment. The consequences in adult lif
e of intrauterine undernutrition now highlight prenatal care as one of
the most crucial issues in medicine and challenge many aspects of cur
rent obstetric decision-making. Research targeting fetal growth and de
velopment can be expected to result in improved health at all ages. (C
