The Effects Over Early Brain Development of a Nurse Home Visitation Program for Pregnant Youth and Their Families Living in a Poor Urban Area in São Paulo, Brazil II

Home visiting programs for pregnant women aiming to improve mother-infant relationship has received worldwide attention in the past 30 years. These programs are considered an important strategy to improve women's health during pregnancy, aside from improving child's birthing conditions and allowing parents access to tools which will nurture and properly stimulate their baby, thus promoting emotional and cognitive development. Objectives: The "Nurse home visitation program for pregnant youth" aims to promote infant´s healthy development, from pregnancy to the first months of life, in a high-risk population. Methods: Eighty young pregnant women aged between 14 and 21 years were randomly allocated to the intervention or to usual prenatal care program. The "Nurse home visitation program for pregnant youth" was developed based on Albert Bandura's theory of self-efficacy, on Urie Bronfenbrenner´s bioecological model, which recognizes the importance of individual and family inclusion in various contexts of social life, on John Bowlby and Mary Ainsworth evolutionary theories of attachment, which involves the care practitioner addressing issues such as environmental health, life course and parenting, bond between mother and infant, and infant´s social and cognitive development. Neuropsychomotor development will be assessed at 3, 6, 12 and 24 months using the Bayley Scale of Infant Development. Brain development will be assessed via electroencephalography at 6, 12 and 24 months.
