The Medical Research Council’s pioneering National Survey of Health and Development (NSHD), also known as the 1946 birth cohort, was the first ever British birth cohort study and it is still going strong today.
Set up by Dr James Douglas in March 1946, we now celebrate the 65th birthday of the ‘Douglas children’, the study members who have allowed us to follow them throughout their lives in one of the longest running studies of human development in the world.
