1970 BCS 42 months sub-sample (1973)

As with the sub-study at 22 months, at 42 months a sub-sample (N = 2,315) of BCS70 children were studied, with the aim of exploring the effect of foetal malnutrition in brain cell proliferation. A 10% random sample of all births was included together with those children who were considered to be at risk from foetal malnutrition.
