We must talk to the mother by telephone to determine if a family is eligible to be in the study. If a family is eligible and decides to be in the study, the family will be asked to do the following study activities:

Complete two telephone interviews

The first telephone interview will be to ask the mother questions about the dates of her pregnancy with the enrolled child and prepare for other study activities. During the second telephone interview, we will ask the mother questions about her health before and during her pregnancy and about the child’s health and development.

During the study parents will be asked to complete a set of questionnaires. These can be mailed to the home to complete or we can schedule time for a parent to complete them over the telephone with one of our study staff.

Clinic visit – child and parent activities

Parents of some children will bring the child to the study clinic for an assessment of his or her development. The assessment is done by a trained clinician and includes playing some games with the child and asking him or her some questions. A few weeks after the assessment we will send the family a letter describing the developmental assessment results. At the time of the visit, we will also measure height, weight and head size of the child and collect some saliva.

We will ask some parents more questions about the child, measure their height and head circumference, and ask them to provide a saliva sample. This can be scheduled for the same day as the child’s clinic visit or for another day.
