The periodic evaluation of development in cognition, motor skills, language and social behavior is a contribution in the early detection of risks. Some biological and environmental risk factors increasesthe probability of deficits in a child´s development. The greater the number of risk factors to which a child is exposed, the greater the possibility of compromise in their development. The importanceof biological and environmental risk factors for child development has already been widely studied, in populations at risk, however, relatively little has been studied in the population of healthy, termbornchildren. We administered the Argentine Scale of sensory motor intelligence (EAIS) to 956 Argentinean children from 6 to 30 month old, healthy, born at term, with normal birth weight. The EAIS is the first Argentinean scale that allows early detection of cognitive delays in children. We observed that the infant´s age older than 15 months old, is associated to risk level in cognitive development. Infants with gestational age less than 39 weeks gestations obtained higherfrequencies of delay in cognitive development. Children of 37 weeks of gestation were the most affected in cognitive development. Younger mothers tended to be associated with cognitive development delay in their children. And finally, having an unemployed father or lack of supportfrom child father and mother´s family was associated to delay in cognitive development. We highlight the importance of the periodic development evaluation even during the second year old of life in healthy infants and we propose to rethink the cognitive development features and the evaluation in infants, born at 37 and 38 gestational weeks. We consider environmental risk factors are indicators of socioeconomic status.
