UK Biobank men and women were less likely to be current smokers than the general population across all age groups, based on data from the HSE 2008 (Figure 2). For example, for men aged 45–54 years, the prevalence of current smoking was 15% in UK Biobank and 22% in the general population; the corresponding values for women were 11% and 20%, respectively. However, younger smokers (aged 45–54 years) in UK Biobank smoked more heavily (≥20 cigarettes/day) than those in the general population (46% and 41%, respectively, for men; 32% and 28%, respectively, for women). This difference persisted for older women aged 55–64 years (31% and 23% in UK Biobank and the general population, respectively) but not for older men (47% and 49%, respectively; Web Figure 2). UK Biobank participants were also less likely to be never drinkers but were less likely to drink alcohol every day than the general population included in the HSE 2008 (Table 4).
