Summary:Childhood intelligence is an important determinant of health outcomes in adulthood. The first years of life are critical to child development. This study aimed to identify early life (perinatal and during the first year of life) predictors of low cognitive performance at age 6. A birth cohort study started in the city of Pelotas, southern Brazil, in 2004 and children were followed from birth to age six.
