Abstract
The early socio-economic differences in smoking build on the interplay between individual-, family-, peer-, and school-related factors. The present study aimed to add knowledge to this by examining susceptibility to smoking (S-SM), electronic cigarette (e-cigarette) use (S-EC), and smokeless tobacco (snus) use (S-SN) by educational aspirations in a country with advanced tobacco control policies. National cross-sectional School Health Promotion study survey was conducted among 8.-9. grade students (av. 15-year-olds) in 2017 with no prior smoking (n = 47 589), e-cigarette use (n = 49 382), or snus use (n = 53 335). Gender-stratified, age-adjusted multilevel logistic regression analyses with S-SM, S-EC, and S-SN were considered as outcomes and student- and school-level (aggregated) factors were considered as independent variables. The highest prevalence was observed for S-EC (girls 29%, boys 35%), followed by S-SM (16%, 15%) and S-SN (10%, 16%). Compared to those planning for general upper secondary education, S-SM was the highest for those without educational aspirations (OR = 1.20, 95% CI = 1.04-1.40), S-EC for those planning for vocational education [1.15 (1.05-1.25)], and S-SN for those planning for extra year/discontinuation [1.65 (1.04-2.60)] among girls. Among boys, both S-SM [1.37 (1.23-1.52)] and S-EC [1.19 (1.09-1.29)] were the highest among those planning for vocational education, with no clear associations with S-SN. Current other tobacco/e-cigarette use [OR range 1.27-8.87], positive attitude towards product use in one's age group [3.55-6.63], and liking school [0.58-0.68] consistently associated with susceptibility. Students not planning for academically oriented education had higher susceptibility to different nicotine products. High S-EC warrants monitoring to strengthen policy evaluation and prevention.
