Smoking prevalence by age

 Current smoking prevalence by grade/age, Grades 7-9, 2012-13, and age 15-19, 2013. Data for Gr. 6, Gr. 7 'daily', and age 15 ‘daily’ not reportable due to low numbers in the numerator and/or denominator; overall prevalence shown for Gr. 7 . Data sources: Canadian Tobacco, Alcohol and Drugs Survey, 2013; Youth Smoking Survey, 2012-13. See data table with 95% confidence intervals below.

Smoking prevalence appeared to increase with age: rates were too low to report among Grade 6 students, but increased fairly steadily to 18.5% of 19-year-olds (Figure 8.3).

As noted, data up to Grade 9 is provided by the Youth Smoking Survey (YSS), and data from Canadian Tobacco Use Monitoring Survey (CTUMS) is used for older youth. Any difference observed between Grade 9 students and 15-year-olds could be due to differences in survey methodologies.

Among students in Grades 7-9, smoking patterns by grade were fairly consistent between 2002 and 2012-13, and prevalence was much lower in these years than in 1994 (Figure 8.4).

Over time, smoking among youth aged 15-17 declined fairly steadily. Smoking among 18- and 19-year-olds has also declined, although with less consistency (slight increases in some years), and has plateaued in recent years (Figure 8.4). This has led to a greater difference in smoking rates between older and younger adolescents: in 2013, the smoking rate among 18- and 19-year-olds was nearly triple that of 15- to 17-year-olds.
