Aims: To identify demographic and social correlates of (a) relative harm perceptions of e-cigarettes (ECs), and (b) harm perceptions of nicotine, amongst GB youth.
Design: Cross-sectional survey.
Setting: Online GB survey, 2016.
Participants: 2103 youth aged 11-18.
Measurements: Explanatory variables: Gender, age, region, social grade, smoking/EC status, family smoking/EC use, perceived friends’ smoking, perceived public approval of smoking/ECs. Outcomes: (a) relative harm perceptions of ECs vs. cigarettes, (b) harm perceptions of nicotine.
Findings and conclusions: 63.4% of youth believed that ECs are less harmful than cigarettes, and 26.3% believed that none or some of the risk from smoking comes from nicotine. Correlates of believing that ECs are less harmful than cigarettes were: being male (OR=0.82, 95% CI=0.67=0.99, p=.035), older (OR=1.11, CI=1.07-1.16, p<.001), family member(s) using an EC (OR=2.29, CI=1.60-3.26, p<.001), perceiving that the public disapprove of smoking (OR=0.50, CI=0.30-0.82, p=.006) and approve of ECs (OR=2.53, CI=1.85-3.47, p<.001), and not knowing how many friends smoke vs. 0 smoking friends (OR=0.47, CI=0.29-0.78, p=.004). Correlates of believing that none or some of the risk from smoking comes from nicotine were: being male (OR=0.63, CI=0.51-0.78, p<.001), older (OR=1.32, CI=1.26-1.39, p<.001), higher social grade (OR=0.75, CI=0.60-0.94, p=.013), having tried an EC (OR=1.69, CI=1.22-2.35, p=.002) and family member(s) using an EC (OR=1.41, CI=1.01-1.98, p=.045). Smoking status was not associated with either belief (p>.05). The majority of youth have accurate harm perceptions of e-cigarettes but not nicotine. Accurate harm perceptions of e-cigarettes were associated with positive social norms surrounding EC use and negative social norms surrounding smoking.
