Growth and Obesity Chilean Cohort Study (ECO)
ECO investigates the links between parent obesity and child growth in a cohort of children in Chile. The study included preschool children between 2 and 4 years old attending a National Association of Day Care Centers (Junta Nacional de Jardines Infantiles, JUNJI) nursery school in any of the six counties in Southeastern Santiago, Chile. Participants were singletons who weighed at least 2.5 kilograms at birth without physical or psychological conditions that could severely affect growth. At baseline, over 1,100 participants were included in the study. The cohort consisted of an equal proportion of girls and boys.
