RESUMO
INTRODUCTION: Raising cigarette prices, increasing graphic health warning label (HWL) coverage and requiring plain packaging could reduce cigarette smoking in Vietnam. This discrete choice experiment estimates the potential impact of these policies on smoking behaviour. METHODS: In February-May 2022, we conducted a phone-based, cross-sectional survey of 1494 Vietnamese adults who smoke. Participants were randomly assigned to view four individual cigarette pack images, varied on price (15 000 (reference group); 20 000; 30 000 or 40 000 Vietnamese dong (VND)) and packaging (branded pack with 50% graphic HWL (reference group); branded pack with 85% graphic HWL; plain pack with 50% graphic HWL or branded pack without HWL). Participants responded if they would quit or continue smoking if they could only purchase the pack shown. We used binomial logistic regressions to estimate the relative risk (RR) of price and packaging on hypothetical quitting. RESULTS: Participants were more likely to report they would quit when presented with 30 000 VND (RR 1.20, 95% CI 1.07 to 1.35) and 40 000 VND packs (RR 1.40, 95% CI 1.23 to 1.58) vs the 15 000 VND pack. Participants were also more likely to report they would quit when shown the branded pack with 85% HWL (RR 1.30, 95% CI 1.18 to 1.42) and plain pack with 50% HWL (RR 1.34, 95% CI 1.21 to 1.49) vs the branded pack with 50% HWL coverage. Participants had significantly lower quit likelihood (RR 0.41, 95% CI 0.35 to 0.48) when shown the branded pack without a HWL. CONCLUSIONS: Results suggest raising cigarette prices to at least 30 000 VND, implementing larger graphic HWLs or plain packaging could decrease smoking rates in Vietnam.
RESUMO
OBJECTIVE: To assess how first experimenting with ciga-rettes or e-cigarettes is associated with current use in Gua-temala, a middle-income country with weak tobacco control and no e-cigarette regulations. MATERIALS AND METHODS: We surveyed students from private schools in Guatemala City, limiting analyses to ever users (n=1 026). Multinomial logistic models regressed current product use on first product used, adjusting for sociodemographics and friends and family use. RESULTS: The most common first product used was e-cigarettes (56%), followed by flavored cigarettes (24%) and regular cigarettes (20%). At the time of the survey, 4% were exclusive smokers, 37% were exclusive e-cigarette users, 18% dual users, and 40% had ever tried either but were not current users. Compared to those who first tried cigarettes, students who first tried e-cigarettes were less likely to be current smokers (RR=0.19 [CI: 0.11,0.31]) or dual users (RR=0.26 [CI: 0.14,0.49]) and students who first tried flavored cigarettes were more likely to be current smokers (RR=1.66 [CI=1.13,2.42]). CONCLUSIONS: In our sample, Guatemalan adolescents from private schools more frequently experiment and continue to use e-cigarettes than cigarettes. There is urgent need to implement e-cigarette restrictions in addition to tobacco control policy implementation.

Guatemala is one of the few countries where both heated tobacco products (HTPs) and electronic cigarettes (e-cigarettes) remain unregulated. We used a discrete choice experiment (DCE) administered to 2038 high school students to assess how tobacco product attributes influence their appeal among Guatemalan adolescents. Participants were randomly assigned to evaluate 4 of 32 contrasting sets, each containing 3 packs (1 of each product type). Experimental manipulations included: product type, brand, nicotine content and flavor. Participants then indicated which product they were most and least interested in trying and would be most and least harmful to their health. Conditional logistic regression models were used to assess the impact of product characteristics on choice. Product type accounted for almost 90% of variation in choices. Respondents were less interested in trying HTPs (B = -0.93; p < 0.001) and viewed them as more harmful (B = 2.77; p < 0.001) compared to cigarettes. They were more interested in trying e-cigarettes (B = 1.22; p < 0.001), which were also perceived as less harmful (B = -1.47; p < 0.001) compared to cigarettes. Products without nicotine were of more interest for trying (B = 0.14; p < 0.001) and perceived as more harmful (B = 0.20; p < 0.001) than those with. Students were more interested in trying a flavor compared to regular tobacco and among the flavors, berry was the highest rated one (B = 0.28; p < 0.001). Finally, in this country with weak tobacco control, e-cigarettes appear to be more appealing and perceived as less harmful than HTPs and cigarettes. Packaging and flavoring regulations are urgently needed on these products as they are a marketing strategy targeting adolescents.

INTRODUCTION: Cigarette packaging is a primary channel for tobacco advertising, particularly in countries where traditional channels are restricted. The current study evaluated the independent and interactive effects of cigarette packaging and health warning label (HWL) characteristics on perceived appeal of cigarette brands for early adolescents in Mexico. METHODS: A discrete choice experiment (DCE) was conducted with early adolescents, aged 12-14 years (n=4251). The DCE involved a 3×25 design with six attributes: brand (Marlboro, Pall Mall, Camel), tobacco flavour (regular, menthol), flavour capsule (none, 1 or 2 capsules), presence of descriptive terms, branding (vs plain packaging), HWL size (30%, 75%) and HWL content (emphysema vs mouth cancer). Participants viewed eight sets of three cigarette packs and selected a pack in each set that: (1) is most/least attractive, (2) they are most/least interested in trying or (3) is most/least harmful, with a no difference option. RESULTS: Participants perceived packs as less attractive, less interesting to try and more harmful if they had plain packaging or had larger HWLs, with the effect being most pronounced when plain packaging is combined with larger HWLs. For attractiveness, plain packaging had the biggest influence on choice (43%), followed by HWL size (19%). Interest in trying was most influenced by brand name (34%), followed by plain packaging (29%). Perceived harm was most influenced by brand name (30%), followed by HWL size (29%). CONCLUSION: Increasing the size of HWLs and implementing plain packaging appear to reduce the appeal of cigarettes to early adolescents. Countries should adopt these policies to minimise the impact of tobacco marketing.
RESUMO
BACKGROUND: The US Food and Drug Administration (FDA) has regulatory authority to use inserts to communicate with consumers about harmful and potentially harmful constituents (HPHCs) in tobacco products; however, little is known about the most effective manner for presenting HPHC information. METHODS: In a discrete choice experiment, participants evaluated eight choice sets, each of which showed two cigarette packages from four different brands and tar levels (high vs low), accompanied by an insert that included between-subject manipulations (ie, listing of HPHCs vs grouping by disease outcome and numeric values ascribed to HPHCs vs no numbers) and within-subject manipulations (ie, 1 of 4 warning topics; statement linking an HPHC with disease vs statement with no HPHC link). For each choice set, participants were asked: (1) which package is more harmful and (2) which motivates them to not smoke; each with a 'no difference' option. Alternative-specific logit models regressed choice on attribute levels. RESULTS: 1212 participants were recruited from an online consumer panel (725 18-29-year-old smokers and susceptible non-smokers and 487 30-64-year-old smokers). Participants were more likely to endorse high-tar products as more harmful than low-tar products, with a greater effect when numeric HPHC information was present. Compared with a simple warning statement, the statement linking HPHCs with disease encouraged quit motivation. CONCLUSIONS: Numeric HPHC information on inserts appears to produce misunderstandings that some cigarettes are less harmful than others. Furthermore, brief narratives that link HPHCs to smoking-related disease may promote cessation versus communications that do not explicitly link HPHCs to disease.

OBJECTIVE: In 2012, a new Brazilian regulation prohibited the use of flavor additives in tobacco products. To better understand the potential impact of this regulation, this study examines how flavor descriptors on cigarette packaging influence brand perceptions among young Brazilian women. METHODS: An online cross-sectional experiment was conducted with Brazilian women aged 16-26 (N = 640: 182 smokers and 458 nonsmokers) who rated 10 cigarette packages from one of three conditions: 1) branded packs; 2) packs with the same size, shape, and verbal descriptions as in condition 1, but without brand imagery (i.e., "plain pack"); and 3) packs from condition 2 but without brand descriptors (i.e., "plain pack, no descriptors"). Mixed-effects linear regression models were utilized to determine what associations that pack features (i.e., experimental condition; flavor descriptor vs. not; slim pack vs. not) had with participant ratings of nine characteristics, including appeal, taste, smoothness, and attributes of people who smoke the brand. RESULTS: Flavored branded packs were rated as more appealing, better tasting, and smoother than flavored plain packs with descriptors. Compared to flavored plain packs with descriptors, the same packs without descriptors were rated less positively on eight of the nine characteristics. Compared to nonsusceptible nonsmokers, susceptible nonsmokers rated flavored packs more positively on eight of the nine characteristics. Slim packs were rated more positively than regular packs on eight of the nine characteristics. CONCLUSIONS: Slim packs and brands highlighting tobacco flavors appear to increase positive perceptions of tobacco products. Banning tobacco flavorings and slim packs may reduce the appeal of smoking for young Brazilian women, as well as for other vulnerable populations.
RESUMO
OBJECTIVES: In the past decade, waterpipe smoking (a.k.a. hookah, shisha, narghile) has become a global phenomenon. In this review, we provide an updated picture of the main epidemiological trends in waterpipe smoking globally. DATA SOURCES: Peer-reviewed publications indexed in major biomedical databases between 2004 and 2014. Search keywords included a combination of: waterpipe, hookah, shisha along with epidemiology, patterns, prevalence and predictors. We also used different spellings of waterpipe terms commonly used. STUDY SELECTION: The focus was on studies with large representative samples, national data or high-quality reports that illuminated aspects of the epidemiology and trends in waterpipe smoking. DATA EXTRACTION: Multiple researchers extracted the data independently and collectively decided on the most important and pertinent studies to include in the review. DATA SYNTHESIS: Waterpipe smoking has become a global phenomenon among youth. The global waterpipe epidemic is likely driven by (1) the introduction of manufactured flavoured tobacco (Maassel); (2) the intersection between waterpipe's social dimension and thriving café culture; (3) the evolution of mass communication media; (4) the lack of regulatory/policy framework specific to the waterpipe. Waterpipe smoking is becoming the most popular tobacco use method among youth in the Middle East, and is quickly gaining popularity elsewhere. Important patterns of waterpipe smoking include the predominance among younger, male, high socioeconomic, and urban groups. Intermittent and social use are also noted patterns. CONCLUSIONS: Waterpipe smoking has become a global public health problem. Developing surveillance, intervention and regulatory/policy frameworks specific to the waterpipe has become a public health priority.

AIMS: To measure the effects of changing attributes of pictorial health warning labels (HWLs) on cigarette packs in a country that has already implemented pictorial HWLs. MEASURES: For each choice set, participants were presented with two cigarette packs and asked the following three questions: (1) 'If only these two cigarette packs were available, which would you buy?'; (2) 'Each of these two packs has warnings on the front and back about the health effects of smoking. Which of these warnings best informs you about the dangers from smoking?'; and (3) 'Which warning most makes you think about quitting smoking?'. As recommended for best practices in discrete choice experiments, each of these questions was followed by an 'opt-out' question for participants to indicate whether they really believed there was a difference between the options presented (i.e. 'Would you really choose one of them?'; 'Do you really think that either of these warnings informs you about dangers from smoking?'; or 'Do you really think that either of these warnings would make you think about quitting smoking?', respectively). Each choice set could be viewed for as long as the participant wished. For each choice question (i.e. willingness to buy, informative, motivating to quit), the pack chosen was coded as 1 and the other pack as 0, with both packs being given a value of 0 if the participant 'opted out'. DESIGN: A within-subject discrete choice experiment that involved systematic manipulation of pictorial HWL size [75 versus 30% (current policy)]; inclusion of imagery on the back of the pack [versus none (current policy)]; and color formatting [black on yellow versus yellow on black (current policy)]. SETTING: Mexico, on-line panel. PARTICIPANTS: Adult smokers (n = 705). MEASUREMENTS: For each choice set, participants selected one pack as having the most informative HWL about smoking harms, the one that makes them think the most about quitting and the one they were most willing to buy. We assessed the independent and interactive effects of HWL attributes on choices. FINDINGS: Larger HWL size on the pack front (75 versus 30%) and inclusion of a pictorial image on the pack back were both independently associated with lower willingness to buy a pack [b = -0.228, standard error (SE) = 0.023 and -0.089, SE = 0.016, respectively] and greater perception of an HWL as informative (b = 0.214, SE = 0.022, and 0.191, SE = 0.017, respectively) and motivating to quit (b = 0.251, SE = 0.023 and 0.194, SE = 0.017, respectively). HWL with black text and yellow background were perceived as less informative (b = -0.037, SE = 0.016) and less motivating to quit (b = -0.032, SE = 0.015) compared with yellow text on a black background. CONCLUSIONS: Among adult Mexican smokers, pictorial health warning labels on cigarette packages that are larger or cover both sides of the pack appear more effective at lowering purchase intentions and increasing risk perceptions and motivation to quit than smaller health warning labels or health warning labels with imagery only on the pack front.

Background: In Bangladesh, the neonatal mortality rate has remained relatively high at 23 deaths per 1000 live births. Consistent adoption of essential newborn care (ENC) practices should lower this rate significantly. This study assessed whether the presence of skilled birth attendants (SBAs) in home deliveries improved ENC practices in Bangladesh. Methods: Data from the Bangladesh Demographic and Health Survey 2014 on mothers who reported home birth in the previous 3 y was utilized (n=2761 out of 4904 total births). SBAs include all types of healthcare providers who have received formal training in obstetric care. A generalized structural equation model was used to explore factors affecting (1) utilization of antenatal care, (2) choice of birth attendants and (3) adoption of ENC practices. Results: One-quarter (25.7%) of home births were delivered by an SBA. SBAs performed ENC practices more often than traditional birth attendants (thermal care, 15.0% of skilled deliveries vs 10.1% of unskilled; cord care, 71.6% vs 62.9%; early breastfeeding, 63.9% vs 58.6%). The presence of an SBA during delivery resulted in a greater likelihood of receiving ENC practices. Conclusion: Although SBAs performed the recommended activities at a higher rate than the unskilled across all outcomes, the proportion of SBAs performing ENC practices is still low. It is important for policymakers to identify strategies to improve the effectiveness of SBAs in home deliveries.

OBJECTIVES: Our aim was to identify message characteristics for cigarette pack inserts that aim to help smokers quit. METHODS: US adult smokers from an online consumer panel (N = 665) participated in a discrete choice experiment with a 2x2x2x2x4 within-subjects balanced incomplete block design, manipulating: image (vs no image), text type (testimonial vs informational), cessation resource information (vs none), call to action (vs none), and message topic (well-being, financial benefit, cravings, social support). Participants evaluated 9 choice sets, each with 4 inserts, selecting: (1) the most and least helpful for quitting; and (2) the most and least motivating to quit. Linear models regressed choices on insert characteristics, controlling for sociodemographics and smoking-related variables. We assessed interactions between insert characteristics and smoker attributes (ie, education, quit intention, self-efficacy). RESULTS: Inserts were most helpful and motivating when they included an image, provided cessation resource information, or referenced well-being and financial benefits. Significant interactions indicated that inserts with cessation resource information were relatively more helpful and motivating among smokers with low self-efficacy, an intention to quit, or lower education. CONCLUSION: Cigarette pack inserts with imagery and cessation resource information may be particularly effective in promoting smoking cessation.
RESUMO
This study assessed smokers' responses to different smoking cessation topics and imagery for cigarette package inserts. Adult smokers from Canada (n = 1000) participated in three discrete choice experiments (DCEs): DCE 1 assessed five cessation benefit topics and five imagery types; DCE 2 assessed five messages with tips to improve cessation success and five imagery types; DCE 3 assessed four reproductive health benefits of cessation topics and four imagery types. In each DCE, participants evaluated four or five sets of four inserts, selecting the most and least motivating (DCEs 1 & 3) or helpful (DCE 2) for quitting. Linear mixed models regressed choices on insert and smoker characteristics. For DCE 1, the most motivating messages involved novel disease topics and imagery of younger women. For DCE 2, topics of social support, stress reduction and nicotine replacement therapy were selected as most helpful, with no differences by imagery type. For DCE 3, imagery influenced choices more than topic, with imagery of a family or a mom and baby selected as most motivating. Statistically significant interactions for all three experiments indicated that the influence of imagery type on choices depended on the message topic. Messages to promote smoking cessation through cigarette pack inserts should consider specific combinations of message topic and imagery.

BACKGROUND: More than 90% of all low birthweight (LBW) babies are born in developing countries, and half of the population in developing nations uses solid fuels as their primary source of energy for cooking. An association between household use of solid biomass fuels and reduced newborn weight has been found in a number of countries. Bangladesh has a high prevalence of LBW babies (22%), and 88% of the population use solid fuels for cooking. OBJECTIVES: This study aims to explore whether indoor air pollution is associated with LBW in Bangladesh, an important determinant of infant mortality and morbidity. METHODS: The 2011 Bangladesh Demographic and Health Survey (BDHS) was used for the present analysis. The total number of births reported in the previous five years by respondents in the survey sample was 8,753. Mothers' recall of their baby's weight was the dependent dichotomous variable. A mixed effects logistic regression model was fitted using region as a random effect and several independent fixed effects. RESULTS: High pollutant cooking fuels, such as coal and wood, resulted in higher odds of having a LBW child compared to use of electricity/gas (odds ratio (OR): 2.6, confidence interval (CI): 1.1-6.2 and OR: 1.1, CI: 1.0-1.2). Factors which lowered the odds include mothers with a bachelor's degree or higher education (OR: 0.6, CI: 0.4-0.9), third order children (OR: 0.8, CI: 0.6-0.9), fourth or higher order children (OR: 0.8, CI: 0.6-1.0), having a male child (OR: 0.7, CI: 0.7-0.8), and receiving sufficient antenatal care (OR: 0.8, CI: 0.6-0.9). Factors which increase the odds of having a LBW infant include mothers who are underweight compared to normal weight mothers (OR: 1.1, CI: 1.1-1.2), mistimed pregnancies (OR: 1.2, CI: 1.0-1.4), or unplanned pregnancies (OR: 1.3, CI: 1.0-1.7), compared to planned pregnancies. CONCLUSIONS: This is the first paper to show an association between use of highly pollutant biomass fuel and prevalence of LBW babies in Bangladesh, suggesting that besides polluting the air and causing respiratory illnesses, biomass fuel combustion may also affect the health of fetuses in utero. Further longitudinal studies are required to establish this finding among mothers in developing countries.
RESUMO
OBJECTIVES: Youth have the misperception that waterpipe smoking is less harmful than cigarettes despite the evidence that it is associated with nicotine dependence and many of the diseases caused by cigarettes. There is a pressing need to identify effective health warnings that increase awareness about the harmful effects of waterpipe smoking. Our objective was to test the effectiveness of various health warning messages and their location on waterpipe devices. METHODS: Adult waterpipe smokers from a large US university (N = 367) completed an internet-based survey that tested the effect of text-only and pictorial health warning labels and their location on different parts of waterpipe smoking devices. RESULTS: Text-only messages and pictorial labels warning about harm to children were the most effective in motivating waterpipe smokers to think about quitting. In terms of warning label location, the base, mouthpiece and stem are all equally noticeable locations. CONCLUSIONS: This is the first study to test waterpipe-specific warning labels and location on the waterpipe device. Placing waterpipe-specific labels on waterpipe devices may be an effective policy tool to curb waterpipe smoking.

To reduce the many adverse health outcomes associated with intimate partner violence (IPV), high-risk groups need to be specifically targeted in the fight against domestic violence in India. This study aims to examine the prevalence and correlates of IPV in HIV-positive and HIV-negative women from India. A convenience sample of HIV-positive and HIV-negative women responded to questionnaires to assess their experience and perception of violence. Multivariate logistic regression analysis was used to model the association between IPV and age, education, employment status, contraception use, age at first marriage, and HIV status. Although adjusting for age, education, employment status, contraception use, age at first marriage, and HIV status, women who are employed were 3.5 times more likely to suffer IPV (confidence interval [CI] = [1.5, 8.5]), women aged 18 or above at first marriage are 0.3 times less likely to face IPV (CI = [0.1, 0.6]), and women who use contraception are 7 times more likely to suffer IPV (CI = [1.4, 30.2]). Also, HIV-positive women are 3 times more likely to face sexual violence compared with HIV-negative women (CI = [1.1, 7.6]).

INTRODUCTION: Waterpipe tobacco smoking is prevalent among college students in the U.S. and increasing in popularity. Waterpipe smoking establishments are almost completely unregulated, and limited information exists documenting the expansion of this industry. The objective of this study was to identify U.S.-based waterpipe establishments and measure their proximity to colleges/universities. METHODS: Waterpipe establishments and their addresses were compiled using five Internet-based directories during 2014 and analyzed in 2015. Addresses were geocoded and overlaid on a U.S. map of accredited colleges/universities. Proximity of colleges/universities to the nearest waterpipe establishment was measured in 3-mile increments. Multinomial logistic regression was used to model the factors associated with proximity of waterpipe establishments to colleges/universities. RESULTS: A total of 1,690 waterpipe establishments and 1,454 colleges/universities were included in the study. Overall, 554 colleges/universities (38.1%) were within 3 miles of a waterpipe establishment. Proximity of waterpipe establishments to colleges/universities was associated with higher full-time student enrollment. Public colleges/universities and those with a smoke-free campus policy were at lower odds of having waterpipe establishments within 3 miles of their campuses. CONCLUSIONS: Waterpipe smoking establishments are more likely to be located near large colleges/universities. This study should inform initiatives aimed at reducing retail tobacco establishment exemptions.

OBJECTIVES: Waterpipe smoking is highly prevalent among university students, and has been increasing in popularity despite mounting evidence showing it is harmful to health. The aim of this study was to measure preferences for waterpipe smoking and determine which product characteristics are most important to smokers. SETTING: A large university in the Southeastern USA. PARTICIPANTS: Adult waterpipe smokers attending the university (N=367). DESIGN: Participants completed an Internet-based discrete choice experiment to reveal their preferences for, and trade-offs between, the attributes of hypothetical waterpipe smoking sessions. Participants were presented with waterpipe lounge menus, each with three fruit-flavoured options and one tobacco flavoured option, in addition to an opt out option. Nicotine content and price were provided for each choice. Participants were randomised to either receive menus with a text-only health-warning message or no message. OUTCOME MEASURES: Multinomial and nested logit models were used to estimate the impact on consumer choice of attributes and between-subject assignment of health warnings respectively. RESULTS: On average, participants preferred fruit-flavoured varieties to tobacco flavour. They were averse to options labelled with higher nicotine content. Females and non-smokers of cigarettes were more likely than their counterparts to prefer flavoured and nicotine-free varieties. Participants exposed to a health warning were more likely to opt out. CONCLUSIONS: Fruit-flavoured tobacco and lower nicotine content labels, two strategies widely used by the industry, increase the demand for waterpipe smoking among young adults. Waterpipe-specific regulation should limit the availability of flavoured waterpipe tobacco and require accurate labelling of constituents. Waterpipe-specific tobacco control regulation, along with research to inform policy, is required to curb this emerging public health threat.

BACKGROUND: Some waterpipe smokers exhibit nicotine dependent behaviors such as increased use over time and inability to quit, placing them at high risk of adverse health outcomes. This study examines the determinants of dependence by measuring frequency of use among current waterpipe smokers using a large national U.S. METHODS: Data were drawn from four waves (Spring/Fall 2009 and Spring/Fall 2010) of the American College Health Association-National College Health Assessment datasets. The sample was restricted to students who smoked a waterpipe at least once in the past 30 days (N=19,323). Ordered logistic regression modeled the factors associated with higher frequency of waterpipe smoking. RESULTS: Among current waterpipe smokers, 6% used a waterpipe daily or almost daily (20-29 days). Daily cigarette smokers were at higher odds of smoking a waterpipe at higher frequencies compared with non-smokers of cigarettes (OR=1.81; 95% CI=1.61-2.04). There was a strong association between daily cigar smoking and higher frequency of waterpipe smoking (OR=7.77; 95% CI=5.49-11.02). Similarly, students who used marijuana had higher odds of smoking a waterpipe at higher frequencies (OR=1.57; 95% CI=1.37-1.81). CONCLUSIONS: Daily consumers of other addictive substances are at a higher risk of intensive waterpipe smoking and thus higher risk of waterpipe dependence. Intervention programs must incorporate methods to reduce waterpipe dependence and subsequently prevent its deleterious health effects.

ABSTRACT Objective In 2012, a new Brazilian regulation prohibited the use of flavor additives in tobacco products. To better understand the potential impact of this regulation, this study examines how flavor descriptors on cigarette packaging influence brand perceptions among young Brazilian women. Methods An online cross-sectional experiment was conducted with Brazilian women aged 16-26 (N = 640: 182 smokers and 458 nonsmokers) who rated 10 cigarette packages from one of three conditions: 1) branded packs; 2) packs with the same size, shape, and verbal descriptions as in condition 1, but without brand imagery (i.e., "plain pack"); and 3) packs from condition 2 but without brand descriptors (i.e., "plain pack, no descriptors"). Mixed-effects linear regression models were utilized to determine what associations that pack features (i.e., experimental condition; flavor descriptor vs. not; slim pack vs. not) had with participant ratings of nine characteristics, including appeal, taste, smoothness, and attributes of people who smoke the brand. Results Flavored branded packs were rated as more appealing, better tasting, and smoother than flavored plain packs with descriptors. Compared to flavored plain packs with descriptors, the same packs without descriptors were rated less positively on eight of the nine characteristics. Compared to nonsusceptible nonsmokers, susceptible nonsmokers rated flavored packs more positively on eight of the nine characteristics. Slim packs were rated more positively than regular packs on eight of the nine characteristics. Conclusions Slim packs and brands highlighting tobacco flavors appear to increase positive perceptions of tobacco products. Banning tobacco flavorings and slim packs may reduce the appeal of smoking for young Brazilian women, as well as for other vulnerable populations.
RESUMEN Objetivo En 2012, una nueva regulación brasileña prohibió el uso de aditivos de sabor en los productos de tabaco. Para comprender mejor el impacto potencial de esta regulación, este estudio examina cómo los descriptores de sabor en los envases de cigarrillos influyen en las percepciones de marca entre las jóvenes brasileñas. Métodos Se realizó un estudio transversal, en línea con mujeres brasileñas de entre 16 y 26 años (N = 640: 182 fumadores y 458 no fumadores) que calificaron 10 paquetes de cigarrillos de acuerdo a una de las siguientes condiciones: 1) paquetes de marca; 2) paquetes con el mismo tamaño, forma y descripciones verbales que en la condición 1, pero sin imágenes de marca (es decir, "paquete simple"); y 3) paquetes de la condición 2 pero sin descriptores de marca (es decir, "paquete simple, sin descriptores"). Se utilizaron modelos de regresión lineal de efectos mixtos para determinar qué asociación existía entre las diferentes condiciones (es decir, condición experimental, descriptor de sabor vs. no, paquete delgado vs. no) con las calificaciones de los participantes de nueve características, incluyendo atractivo, sabor, suavidad y atributos de personas que fuman la marca. Resultados Los paquetes de marca con sabor se calificaron como más atractivos, de mejor sabor y más suaves que los paquetes simples con sabores y descriptores. En comparación con los paquetes simples con sabores con descriptores, los mismos paquetes sin descriptores fueron calificados de manera menos positiva en ocho de las nueve características. En comparación con los no fumadores no susceptibles, los no fumadores susceptibles calificaron los paquetes con sabor de forma más positiva en ocho de las nueve características. Los paquetes delgados fueron clasificados más positivamente que los paquetes regulares en ocho de las nueve características. Conclusiones Los paquetes delgados y las marcas que destacan los sabores del tabaco parecen aumentar las percepciones positivas de los productos de tabaco. Prohibir los sabores del tabaco y los paquetes delgados puede reducir el atractivo del tabaco para las jóvenes brasileñas, así como para otras poblaciones vulnerables.
RESUMO Objetivo Em 2012, uma nova regulamentação brasileira proibiu o uso de aditivos aromáticos nos produtos tabagísticos. Para entender melhor o impacto potencial desta regulação, este estudo examinou como a propaganda de aroma em embalagens de cigarros influencia a percepção das brasileiras jovens sobre a marca do produto. Método Estudo transversal em que 640 brasileiras (168 fumantes e 458 não fumantes) avaliaram online, uma entre três das seguintes características de 10 pacotes de cigarros: 1) embalagem com a imagem da marca; 2) pacotes com o mesmo tamanho, formato e descrição das características do produto 1, mas sem marca (havia apenas a descrição do produto) e, 3) embalagens nas condições 2, mas sem a descrição do produto (embalagem em branco). O modelo de regressão linear misto foi utilizado para determinar associações das características da embalagem do cigarro (Ex: situação experimental, descrição de aroma versus não, pacotes finos versus não) com as avaliações das participantes para nove características do produto, incluindo a apelação, aroma, suavidade e atributos de quem fuma certa marca. Resultados Pacotes aromatizados de marca foram classificados como mais atraentes, com melhor sabor e suavidade em relação aos que tinham simples descrição do produto. Os pacotes descritos como aromatizados comparados ao mesmo produto sem descrição obtiveram menores escores para oito dentre nove características avaliadas. Em comparação as não fumantes sem suscetibilidade ao tabagismo, as que eram suscetíveis classificaram produtos aromatizados mais positivamente em oito de suas nove características. As embalagens finas receberam julgamento mais positivo do que as com espessura regular para oito dentre nove itens analisados. Conclusões Pacotes finos e marcas que destacam os aromas do tabaco parecem aumentar a percepção positiva deste produto. Proibir a aromatização do tabaco e a oferta de pacotes finos de cigarros reduzem o apelo de fumar entre brasileiras jovens, bem como para outros grupos vulneráveis.
