[Perinatal complications and serotonin level (5-HT) associated with low birth weight].

Background: Studies in human and in experimental models suggest that interaction among the adverse prenatal and postnatal environment increases susceptibility for chronic diseases. This environment could induce changes in the metabolism balance.

Objective: To analyze how the low birth weight (LBW) influences on the perinatal complications and serotonin serum concentration associated with the possible changes in the alimentary behavior.
