Smoking prevalence by sex

See data table below with 95% confidence intervals.Smoking prevalence was not significantly different between male and female students in grades 7-9 in 2016-17.92  Among youth aged 15-19, however, smoking prevalence was significantly greater among males than females in 201793   (Figure 8.5).

Over time, among 15- to 19-year-olds, prevalence patterns have shifted from higher female smoking prevalence (from 1999 until the mid-2000s), to a greater percentage of males smoking for most of the last decade (Figure 8.6).

Among students in grades 7-9, the same general pattern was observed, although with much smaller differences between the sexes: females had slightly higher smoking rates from 1994 to 2004-05, followed by slightly higher rates among males, but equalizing in the most recent waves (Figure 8.6).
