Infant Assessment Unit - Illinois Department of Public Health Data


The Infant Assessment Unit (IAU) was part of the Longitudinal Cohort Study. The objective of the IAU was to observe how prenatal and postnatal conditions affect the health and cognitive functioning of infants during the first year of life. Consisting of several instruments, the IAU sought to measure infant cognition and quantify the experiences of the sampled infants from Cohort 0 during their first 12 months of life. Additionally, the IAU examined the circumstances surrounding the mother's pregnancy and the subsequent care received by the infant. The IAU was administered to subjects or primary caregivers in Cohort 0 only in Wave 1 of the LCS.

The Illinois Department of Public Health (IDPH) Data was included in the IAU to collect information related to the primary caregiver's pregnancy. Information such as age of mother, number of visits to the doctor, whether or not there were complications, length of pregnancy, and baby's birth weight were all recorded in the IDPH file.
