Note that at age 22 and 42 months, due to medical concerns about the effect of fetal malnutrition in brain cell proliferation, a sub-sample of BCS children were studied. A 10% random sample of all births was included together with those children who were considered to be at risk from fetal malnutrition.
At age 34, child assessments were conducted with the cohort member’s children. Each of the cohort member’s eligible children were asked to complete three exercises designed to measure a range of verbal and numerical abilities. Although dependent on the child’s age and abilities, each set of exercises was expected to take an average of 20 minutes to complete.
