Why is the study only looking at children between the ages of 2-5?
The study will focus on children who are 2 to 5 years old. This age range was selected to reduce the amount of time since pregnancy and early development so that parents can remember the events during these time periods is better, so medical information is easier to retrieve, so families are less likely to have moved away from the study area, and so it will also be near the beginning of treatment for children in developmental intervention programs.
