1970 British Cohort Study: 42-Month Subsample, 1973

The 1970 British Cohort Study (BCS70) began in 1970 when data were collected about the births and families of babies born in the United Kingdom in one particular week in 1970. The aim of the 42-month sub-sample survey was to investigate foetal malnutrition and its effect on the subsequent development of the child.
