Cigarette smoking across life from 1946 to 2018: Harmonisation of four British birth cohort studies

In Great Britain, smoking prevalence and cigarette consumption appear to have declined substantially between cohorts born across the latter half of the twentieth and early twenty-first centuries. The British Birth Cohorts represent a unique and largely underutilized resource for investigating trends in smoking across life (prenatal to old age) and by year of birth (1946-2001), including changes in the determinants, correlates, and consequences of smoking. We provide syntax and information on items on smoking in these cohorts to catalyse future research, also available at: https://cls-data.github.io/smoking-in-the-cohorts/.
