The prevalence, trends and heterogeneity in maternal smoking around birth between the 1930s and 1970s

This chapter shows the prevalence, trends and heterogeneity in maternal smoking around birth in the United Kingdom (UK), focussing on the war and post-war reconstruction period in which there exists surprisingly little systematic data on (maternal) smoking behaviours. Within this context, the authors highlight relevant events, the release of new information about the harms of smoking and changes in (government) policy aimed at reducing smoking prevalence. The authors show stark changes in smoking prevalence over a 30-year period, highlight the onset of the social gradient in smoking as well as genetic heterogeneities in smoking trends.
