Effect of e-cigarette advertisement themes on hypothetical e-cigarette purchasing in price-responsive adolescents.

ABSTRACT:

Aims

To examine the effect on adolescents of exposure to different e-cigarette advertisement themes on reported likelihood of purchasing e-cigarettes in a hypothetical scenario.

Design

Between-subjects design of four randomly assigned thematic conditions derived from a content analysis of 350 e-cigarette advertisements: general, flavor- and taste-themed, people- and product use-themed or control advertisements for bottled water.

Setting

Virginia, USA.

Participants

Of 1360 adolescents (13-18 years old) participating, 1063 had complete data (519 current cigarette smokers, 544 tobacco-susceptible non-smokers).

Measurements

Participants completed an e-cigarette purchase task, reporting the likelihood of buying an e-cigarette at various prices. Indices of abuse liability included price responsiveness (whether likelihood of purchase decreased with increasing prices) and, among price-responsive adolescents, breakpoint (highest price before definitely would not buy), maximum probability-weighted expenditure (O_max ) and price elasticity (how quickly willingness to purchase decreases as prices increase). Regressions controlled for demographics, prior tobacco ad exposure, tobacco/substance use and sensation-seeking.

Findings

Prior advertisement exposure was positively associated with being price-responsive [odds ratio (OR) = 1.12, 95% confidence interval (CI) = 1.03, 1.22; P < 0.05]. Among price-responsive adolescents (n = 579), breakpoints were 58% higher in the flavor- and taste-themed condition (β = 0.46, 95% CI = <0.01, 0.92) and 75% higher in the people- and product use-themed condition (β = 0.56, 95% CI = 0.10, 1.03) compared with control (Ps < 0.05). Exposure to people- and product use-themed advertisements was associated with a 60% higher O_max (β = 0.47, 95% CI = 0.01, 0.93; P < 0.05). The general and people- and product use-themed conditions were associated with 19% (β = -0.21, 95% CI = -0.38, -0.04) and 21% (β = -0.24, 95% CI = -0.42, -0.06) lower elasticity, respectively (Ps < 0.05).

Conclusions

E-cigarette advertising exposure may increase reported likelihood of purchasing e-cigarettes, with effects differing by advertisement content. People- and product use-themed e-cigarette advertisements increased reported likelihood of purchasing in price-responsive adolescents.

Project description:BackgroundAppropriate increases in tobacco taxes and prices are an essential component of comprehensive tobacco control strategies. This study investigates factors related to the use, sale, and distribution of cigarettes in Iran, focusing on the relationship between cigarette price and its consumption.MethodsThis interview-based qualitative study was conducted among 20 participants, including cigarette smokers, retail shop owners, large-scale distributors, and an expert in tobacco control research.ResultsSeven themes were extracted from participant interviews, including the type and price of cigarette, the best time to sell cigarettes, profits from the sale of cigarette, affordability, rise in cigarette price and smokers' reaction to it, lobbying and black-market sales of cigarettes, and the sale and distribution of cigarettes across the country. Although the price of cigarettes in Iran has shown some increases in the past decade, the timing of these increases are not predictable and the limited amount of these increases has not reduced the use of cigarettes. Following a price increase, consumers are more likely to switch from buying packets to single cigarettes, or buy a less expensive brand, then to quit. Moreover, increases in prices may encourage smokers and sellers to buy a large number of cigarettes and store them for a rainy day. Another adverse effect may be increased smuggling of illicit cigarettes to balance the pressure caused by rising prices.ConclusionsOur findings highlight two important aspects concerning cigarette pricing in Iran. First is the change in the type of purchase from the whole box of cigarettes to the single stick cigarette or swapping to less expensive cigarettes. Second, increase in cigarette price (either through taxing or regular increases) could be offset by flooding smuggled cigarettes into the market. Therefore, in addition to raising cigarette prices, reducing cigarette consumption rates in Iran requires the development and effective implementation of regulatory policies to control cigarette smuggling, reduce purchasing, and subsequently curb the use of this leading cause of premature morbidity and mortality.
