摘要

Background

Flavored e-cigarettes remain a controversial public health topic, with disagreement on their potential benefits and harms. In this study we compared patterns of flavor use in e-cigarettes at the time of quitting smoking between young adults (18–24 years old) with older adults (> 24 years old).

Methods

A convenience sample of US adults who formerly smoked and reported consuming e-cigarettes every day or some days during the period of quitting smoking were included in the study (N = 51,641) and responded to an online questionnaire. Participants were divided into young adults (n = 9895) and older adults (n = 41746).

Results

The most popular flavors used regularly by young adults and older adults were fruit (92.3% and 81.3%, P < 0.001), followed by dessert/pastry/bakery (67.3% and 68.1%, P = 0.054) and candy/chocolate/sweet (49.7% and 43.3%, P < 0.001). Fruit was the most prevalent single most often used flavor for both groups but was more prevalent in young adults (63.4% vs. 46.0% in older adults, P < 0.001), followed by dessert/pastry/bakery which was more prevalent in older adults (32.1% vs. 22.7% in young adults, P < 0.001). Menthol and mint/wintergreen flavors, while the fourth and fifth most popular flavors used regularly, were the single most often used flavors by only a small minority in both groups. Tobacco flavor was the single most often used flavor by 1.1% of young and 6.0% of older adults (P < 0.001). From logistic regression analysis, being a young adult was positively associated with the use of fruit (OR: 1.65, 95% CI 1.16–2.35), menthol (OR: 1.58, 95% CI 1.09–2.30), mint/wintergreen (OR: 1.51, 95% CI 1.00-2.28) and non-alcoholic/non-coffee drink (OR: 1.83, 95% CI 1.18–2.83) flavors, and negatively associated with the use of tobacco (OR: 0.52, 95% CI 0.34–0.78) flavor at the time of quitting smoking.

Conclusion

Non-tobacco flavors were popular among the US adult former-smoking e-cigarette consumers at the time of quitting smoking, but different flavor preferences exist between young and older adults. Tobacco flavor use prevalence was low, as were menthol and mint/wintergreen, particularly as the single most often used flavors. Future studies should explore patterns of e-cigarette flavor use in young adults who smoke or used to smoke, in addition to those with no smoking history.
