"The 1970 British Cohort Study (BCS70) is a multidisciplinary national longitudinal birth cohort study. Original aims were to examine the social and biological characteristics of the mother in relation to neonatal morbidity, and to compare the results with the 1958 National Child Development Study (NCDS). With each successive sweep, the scope of the enquiry has broadened from a strictly medical focus at birth, to encompass physical, educational, social and economic development. "
