British Doctors Study
The British Doctors Study investigated the lifelong effects of smoking in the United Kingdom. In 1951, all registered British doctors were mailed questionnaires. The studied cohort comprised over 34,000 male doctors, who were followed up with questionnaires in 1957, 1966, 1971, 1978, 1991, 1998 and 2001, as well as through linkage to mortality and cancer records until 2001.
