Maternal undernutrition has been proven to have a profound effect on fetal growth, with body weight and many key organs. It has been reported previously that during the first two weeks of pregnancy, the provision of a 5% protein diet only (undernutrition) led to a reduction in brain weight, size, and cortical thickness of the brain (Gressens et al., 1997). A severe gestational maternal protein restriction in rats caused a reduced number of glomeruli and hypertension in both male and female newborns, this hypertension is salt-sensitive and worsens with age, but is approximately equivalent in males and females (Woods et al., 2004)
Chronic energy deficit or maternal undernutrition means
having a body mass index (BMI) below 18.5. If the females are
under-nourished females at the time of conception, then during
pregnancy (when there are additional demands due to the
growing fetus), they are unlikely to improve their nutritional
status. They are more likely to fail to gain sufficient weight
during pregnancy and are at a higher risk of mortality than wellnourished and healthy women (Smith et al., 2003).
IUGR predisposes developing fetuses to reduced organ and
body weights. Most information about the long-term and short term effects of IUGR has come from animal models. In recent
years, many animal models of placental insufficiency and/or
poor maternal nutrition have been developed to investigate the
causes and effects of IUGR. Both maternal dietary
manipulations and surgical interventions have been employed
for these studies. A number of animal species have been studied
for IUGR effects, including rodents, rabbits sheep, and primates
(Louey et al., 2000; Mitchell et al., 2004; Jonker et al., 2018).
