| Research Abstract |
Recent human studies have shown that intrauterine growth retardation (IUGR) is associated with neurodevelopmental disabilities such as learning disorder, memory impairment and mood disturbance in the offspring. However, the interaction between IUGR with neurodevelopmental disabilities is unclear because of the variety of the causes of IUGR. Fetal development is dependent on the placental supply of nutrition. Undernutrition of childbearing or pregnant woman is, therefore, one of the main causes of IUGR. In this study, we produced an IUGR model by moderate food restriction from pregnancy to the early lactation period in mice. There was low birth weight in the offspring. The IUGR models also showed delayed physical development and behavioral abnormalities such as anxiety and poor cognitive function. These results suggested that an abstemious maternal diet is a risk for not only IUGR but also for neurodevelopmental disability in the offspring.
