Objective:

To test whether electronic cigarettes use among secondary school students in Spain is associated with initiating nicotine use.

Method:

Secondary analysis of the ESTUDES 2019 survey, a cross-sectional study conducted on a representative sample of students aged 14-18 years and selected students who had never smoked (n=16,705). We computed the prevalence and estimated the factors associated with current electronic cigarettes use (at least once in the month before the interview), with and without nicotine.

Results:

The prevalence of current electronic cigarettes use among students who have never smoked is 2.5% (95% confidence interval [95%CI]: 2.2-2.9). 0.1% (95%CI: 0.08-0.2) declared using liquids with nicotine at least sometimes and 2.4% (95%CI: 2.1-2.8) using liquids always without nicotine. Being male and under 17 years of age, reporting binge drinking behavior, and having regular friends who use cannabis, increases the probability of current use of electronic cigarettes. The latter two variables seem to act as contextual variables associated with electronic cigarettes use.

Conclusions:

The percentage of Spanish never smoker students who currently use electronic cigarettes is lower than in neighboring countries, except for the United Kingdom. Only one in every 1000 Spanish students between 14 and 18 years old who have never smoked initiates the current use of nicotine with an electronic cigarette. However, we must monitor the evolution of this indicator.
