Summary
The Study to Explore Early Development (SEED) is a
multi-site national study to understand child
development. The study will include children with autism spectrum
disorders (ASD); children with other types of developmental
disorders; and typically developing children. We plan to enroll a
total of approximately 2,700 children, 2 through 5 years of age, as
well as their parents across the six sites in the United States.
Families living in the Denver Metropolitan area who meet certain
criteria will be asked to participate.
Who can participate?
- Children with ASD, other types of developmental disabilities, or those without developmental disabilities.
- Children who were born between September 2003 and August
2005.
- Children who were born in and currently living in the
Denver metropolitan area (Adams, Arapahoe, Boulder, Broomfield,
Denver, Douglas and Jefferson counties).
Risk Factors of Interest
A number of factors will be studied in SEED, including: infection
and immune function, genetic factors, medical issues and health
behaviors during pregnancy, family history of medical and
developmental problems, parents’ occupation and other
socio-demographic factors, and gastrointestinal and sleep problems
of the child.

Study Activities
Families who take part in the study will be asked to:
- complete questionnaires about the child’s development and the
family’s medical history,
- complete a phone interview about the pregnancy
with the child and child’s development and medical history;
- allow project staff to get copies of the
biological mother’s and child’s medical records;
- provide a blood sample and a sample of cheek
cells from the biological mother, biological father, and child; and
- allow project staff to conduct a developmental
evaluation of the child.
- allow project staff to conduct a brief physical exam on the child
and collect a hair sample.
