Fig. 4

Trends in smoking characteristics and quitting activity among women of reproductive age compared with all adults in England, October 2013 to October 2023 — by occupational social grade. Panels show trends in (A) the proportion of current cigarette smokers mainly smoking hand-rolled (vs. manufactured) cigarettes, (B) the geometric mean level of dependence among current smokers, (C) the proportion of past-year smokers making ≥ 1 past-year quit attempt, and (D) the proportion of past-year smokers who made ≥ 1 past-year quit attempt who were still not smoking at the time of the survey, stratified by occupational social grade. ABC1 = more advantaged, C2DE = less advantaged. Lines represent modelled weighted prevalence (or mean, for level of dependence) by monthly survey wave, modelled non-linearly using restricted cubic splines (five knots). Shaded bands represent 95% confidence intervals
