Abstract | SIGNIFICANCE: Electronic cigarettes (ECs) with nicotine have not been approved
legally in Hong Kong, but low cost ECs with many flavours are on sale and easily
accessible to young people. We studied flavoured EC use and its relation with
smoking intention in never smoking adolescents. METHODS: Of 10923 Secondary
1-6 (US Grade 7-12) students surveyed in 2014/15 in Hong Kong, we analysed
9637 never smokers (n=9637; mean age 14.9, SD 1.8; 49.7% boys). Ever EC
users indicated the flavours they had ever used (study factors) with 9 options, including
“plain flavour”, 7 specified flavours and “other flavours”. Smoking intention
(outcome) referred to choosing any responses other than “definitely not” to smoke
cigarettes (i) in the next 12 months, (ii) when good friends smoked in front, or (iii)
when a good friend offered a cigarette. Descriptive data were weighted by age, sex
and grade. Logistic regression yielded adjusted odds ratios (AORs) of smoking
intention for each flavour and the number of flavours used, with “other flavours”
treated as a single flavour. Socio-demographic characteristics, family smoking
and school clustering effect were adjusted for. RESULTS: In never smokers, 3.2%
(95% CI 2.9%-3.6%) had ever used ECs. No user had used plain flavour, while
mint (78.4%), coffee (36.7%), candy (6.1%), fruits (3.8%), spice (3.4%), alcohol
(1.9%), tobacco (1.6%) and other flavours (25.5%) were reported. Significant associations
were observed between smoking intention and using any flavours versus
never EC use. Candy and tobacco flavours showed the strongest associations
with AOR (95% CI) of 25.44 (7.97-81.13) and 21.42 (1.67-274.37) respectively. In
EC users, 20.8% used 2 flavours and 14.9% used 3 or more. Using more flavours
was more strongly associated with smoking intention, compared with never EC
use. The AOR (95% CI) was 2.62 (1.92-3.59) for 1 flavour, 5.16 (2.94-9.08) for 2
and 9.25 (4.46-19.20) for 3 or more. CONCLUSIONS: Flavoured ECs were popular
in never smoking EC users in Hong Kong adolescents. The strong association
between using more flavours and smoking intention supports a ban on ECs, especially
non-nicotine flavoured ECs, for smoking prevention in adolescents. |
