167: Early childhood overweight and obesity among children born low birthweight or small for gestational age

Abstract

the hippocampus of postpartum mice (Fig 1). In the hypothalamus, the levels of serotonin, dopamine and norepinephrine decreased significantly during pregnancy and postpartum (Table). CONCLUSION: These findings indicate that during pregnancy and the postpartum period there are major changes in mother’s brain of catecholamines levels at sites known to be connected to behavioral changes. The depletion of catecholamines and serotonin during pregnancy and postpartum may be a result of the ageing process of the placenta during pregnancy or the removal of the placenta during labor. Additional data, including that from other mouse strains and behavioral investigations which are on-going will be presented.
