Evaluating the perceived effectiveness of pregnancy-related cigarette package health warning labels among different gender/age groups

IntroductionThe impact of pregnancy-related health warning labels (HWLs) appearing on cigarette packages on women of reproductive age and other socio-demographic groups is not well understood. The current study analyzes how different age/gender groups respond to pregnancy-related HWLs as compared to non-pregnancy HWLs.MethodsData were analyzed from four waves of an online longitudinal study with adult smokers aged 18–64 in Australia, Canada, Mexico, and the US. Participants were classified into four age\gender groups: women 40 and under; men 40 and under; women over 40; men over 40. Participants rated one pregnancy-related and several non-pregnancy related labels on worry, believability, and motivation to quit. Country-specific adjusted linear GEE were estimated regressing ratings for each of the three key outcomes for 1) pregnancy-related HWLs and 2) a rating difference score that subtracted the average ratings of the non-pregnancy warning from the rating of the pregnancy warning. All models adjusted for socio-demographics and smoking related variables.ResultsIn Mexico and Australia, where graphic pregnancy-related HWL imagery is used (i.e., premature infant), women of reproductive age reported stronger believability, worry, and quit motivation than all other groups. Results were similar in the US, where text only HWLs are used. In contrast in Canada, where the pregnancy-related HWL imagery features a pregnant woman, ratings were unassociated with gender/age groups. Stronger effects among women of reproductive age were limited to pregnancy HWLs in each country, except Canada.ConclusionsHWLs that depict graphic effects to illustrate smoking-related pregnancy risks appear to be perceived as particularly effective among women of reproductive age.     

Coping Mechanisms Actually and Hypothetically Used by Pregnant and Non-Pregnant Women in Quitting Smoking

ABSTRACT

The purpose of this article was to investigate how pregnant and non-pregnant women use various coping techniques when attempting to refrain from smoking. Eighty women with subgroups formed by the variables of pregnant/not pregnant and quitting/not quitting smoking were studied over a 2-week period. The general strategy was to follow smokers who had stated an intention to quit smoking. Smokers, pregnant and non-pregnant, who did not intend to quit were also followed with respect to the coping techniques they would hypothetically be using if they were trying to quit. Pregnant women used coping strategies more often than non-pregnant women. Differences found between pregnant and non-pregnant women were evenly distributed for behavioral and cognitive methods. The goal of becoming a non-smoker, especially during pregnancy, needs to be addressed to include psychological and physical factors. In these efforts, the framework introduced by the study involving a time-related approach could be useful.     

Perceived partner responsiveness predicts smoking cessation in single-smoker couples

IntroductionRomantic partners are crucial to successful smoking cessation, but the mechanisms by which partners influence cessation is unclear. Research in this area has focused heavily on partner smoking status and support for quitting, but partner influence may not be limited to these two constructs. The current study examines the perceived responsiveness of the partner (i.e., the perception that the partner understands, approves of, and supports the self) as a predictor of smoking cessation in unassisted quitters, independent of smoking-specific support for quitting and more general relationship satisfaction.MethodsData were taken from a sample of smokers (N = 62) in relationships with never/former smokers (i.e., members of single-smoker couples) who completed a 21-day ecological momentary assessment study during an unassisted quit attempt. Measures of perceived responsiveness, support for quitting, and relationship satisfaction obtained at baseline were used to predict smoking outcomes over the course of the study.ResultsConsistent with our predictions, perceived responsiveness emerged as a significant predictor of smoking cessation over and above the effects of support for quitting and relationship satisfaction. Support for quitting only predicted self-reported relapse. Unexpectedly, once perceived responsiveness was considered, greater relationship satisfaction was associated with poorer smoking outcomes.ConclusionsThe current research suggests that perceived responsiveness is a more effective resource for smoking cessation than support specifically for quitting. These findings extend previous research by demonstrating that perceived responsiveness represents a distinct construct from smoking-specific support or relationship satisfaction, and that it is important for smokers during a quit attempt.     

Emotion regulation difficulties and social control correlates of smoking among pregnant women trying to quit

Approximately 15% of US women currently smoke during pregnancy. An important step toward providing effective smoking cessation interventions during pregnancy is to identify individuals who are more likely to encounter difficulty quitting. Pregnant smokers frequently report smoking in response to intrapersonal factors (e.g., negative emotions), but successful cessation attempts can also be influenced by interpersonal factors (i.e., influence from close others). This study examined the association between emotion regulation difficulties, positive and negative social control (e.g., encouragement, criticism), and smoking cessation-related variables (i.e., smoking quantity, withdrawal symptoms) among pregnant smokers. Data were drawn from the pretreatment wave of a smoking cessation trial enrolling low-income pregnant women who self-reported smoking in response to negative affect (N = 73). Greater emotion regulation difficulties were related to greater smoking urges (b = 0.295, p = .042) and withdrawal symptoms (b = 0.085, p = .003). Additionally, more negative social control from close others was related to fewer smoking days (b = −0.614, p = .042) and higher smoking abstinence self-efficacy (b = 0.017, p = .002). More positive social control from close others interacted with negative affect smoking (b = −0.052, p = .043); the association between negative affect smoking and nicotine dependence (b = 0.812, p < .001) only occurred at low levels of positive social control. Findings suggest that emotion regulation difficulties may contribute to smoking during pregnancy by exacerbating women's negative experiences related to smoking cessation attempts. Negative social control was related to lower smoking frequency and greater confidence in quitting smoking, suggesting that it may assist pregnant smokers' cessation efforts. Positive social control buffered women from the effects of negative affect smoking on nicotine dependence.Trial registrationClinicalTrials.gov, NCT01163864     

Fatigue severity and electronic cigarette beliefs and use behavior

Electronic cigarette (e-cigarette) use has risen dramatically in the United States. Clinically significant fatigue may represent one previously unexplored individual difference factor related to e-cigarette use patterns and e-cigarette specific cognitive processes. Fatigue reflects the experience of being tired, lacking energy, and feeling exhausted. Although fatigue is a normal bodily response, severe or chronic fatigue is maladaptive. Thus, the current study sought to evaluate clinically significant fatigue and its relation to perceived barriers for quitting e-cigarettes, perceived risks and perceived benefits of e-cigarette use, and e-cigarette dependence among 625 adult e-cigarette smokers (51.8% female, M_age = 34.91 years, SD = 10.29). Results indicated that severe fatigue was significantly related to greater perceived barriers to quitting (p < .001), perceived risks (p < .001) and perceived benefits (p < .001) of e-cigarette use, and greater e-cigarette dependence (p < .001); effects that were evident after adjusting for a range of other factors (e.g., combustible cigarette use, pain severity). These novel empirical results highlight the severity of fatigue as a potentially important construct in efforts to better understand beliefs related to e-cigarette use and e-cigarette dependence.     

Psychological distress and responses to comparative risk messages about electronic and combusted cigarettes

BackgroundPeople with mental illness suffer disproportionately high health burdens of smoking. Communicating to these smokers that electronic cigarettes (e-cigarettes) are a less harmful alternative to combusted cigarettes might help them reduce their health risks by encouraging complete switching to e-cigarettes. However, such messages might also cause unintended consequences (e.g., dual use of both combusted and e-cigarettes). Our study examined how smokers with vs. without serious psychological distress (SPD) responded to messages communicating reduced harm of e-cigarettes in relation to cigarettes.MethodIn an online experiment, 1400 U.S. adult smokers with and without SPD viewed 1 of 6 messages about reduced harm of e-cigarettes compared to cigarettes or a control message. Then participants reported e-cigarette- and cigarette-related beliefs, and behavioral intentions.ResultsMessage type (comparative risk messages vs. control) did not interact with SPD status to produce differential impacts on smokers with and without SPD. Regardless of being exposed to a comparative risk message or a control message, smokers with SPD reported greater perceived absolute risk of e-cigarettes and cigarettes, greater support for tobacco control, greater intentions to switch to e-cigarettes completely and seek help with quitting, and were less likely to report e-cigarettes were less harmful than cigarettes compared to smokers without SPD.DiscussionSmokers with SPD had greater intentions to switch to e-cigarettes completely and seek help quitting compared to smokers without SPD, which indicates that smokers with SPD may be optimistic about e-cigarettes to help them quit smoking.     

Anxiety sensitivity and smoking among Spanish-speaking Latinx smokers

Despite the documented health disparities for smoking among the Latinx population, there is limited understanding of transdiagnostic constructs that may help explain smoking among Spanish-speaking Latinx smokers. The present study examined one promising transdiagnostic factor, anxiety sensitivity (fear of anxiety and related sensations), in relation to cigarette dependence, perceived barriers for quitting, and severity of problems experienced when trying to quit among a large sample of Latinx smokers. Participants were 367 Spanish-speaking Latinx daily smokers (59.1% female, M_age = 33.20 years, SD = 11.81). As hypothesized, anxiety sensitivity was significantly related to the severity of cigarette dependence, perceived barriers for quitting, and problems when trying to quit. Inspection of the lower-order dimensions of anxiety sensitivity indicated that Physical Concerns was significantly related to cigarette dependence whereas Cognitive Concerns was associated with greater perceived barriers for quitting and severity of problems experienced during past quit attempts. The present study provides novel empirical evidence that anxiety sensitivity is related to a moderate, yet clinically meaningful, proportion of the variance in cigarette dependence, perceived barriers for quitting, and problems experienced during quit attempts. These findings underscore the value of examining anxiety sensitivity among Latinx smokers and focusing greater attention on this construct in efforts to reduce or quit smoking among this population.     

Perceived addiction to smoking and associations with motivation to stop,quit attempts and quitting success: A prospective study of English smokers

AimsSome argue that perceived addiction to smoking (PAS) might undermine motivation to stop. We examined the association of PAS with motivation to stop in a population sample and assessed its association with past and future quit attempts and future quit success.Method12,700 smokers in England were surveyed between September 2009–March 2012 as part of the Smoking Toolkit Study. 2796 smokers were followed up after 6 months. PAS was assessed at baseline by a single self-report item. The outcome variables were ratings of motivation to stop and reports of past-year quit attempts at baseline, and quit attempts in the past 6 months and smoking status at follow-up. Baseline covariates were sex, age, social grade and daily cigarette consumption.ResultsIn adjusted analyses, PAS was positively associated with at least some degree of motivation to stop versus no motivation (ORs = 1.97–2.96, all p's < 0.001). PAS was also positively associated with past-year quit attempts (OR = 1.43, 95% CI = 1.32–1.55, p < 0.001), but not with future quit attempts (OR = 1.17, 95% CI = 0.99–1.39, p = 0.064) or quit success (OR = 1.04, 95% CI = 0.73–1.47, p = 0.83).ConclusionIn smokers in England, perceived addiction to smoking is positively associated with motivation to stop and having recently made a quit attempt but is not clearly associated with future quit attempts or success. These findings provide no grounds for believing that increasing smokers' perceived addiction through promotion of stop-smoking support has undermined motivation to stop.     

Income as a moderator of psychological stress and nicotine dependence among adult smokers

BackgroundPerceived stress and psychological distress are associated with more cigarette craving and withdrawal, higher nicotine dependence, and less success during quit attempts. Low income smokers have disproportionately higher rates of smoking and may be particularly vulnerable to the effects of stress on smoking dependence. The aim of the current study was to assess if lower income smokers have a stronger association between stress and nicotine dependence than higher income smokers.MethodsData were obtained from the Pennsylvania Adult Smoking Study, which included 351 daily smokers. Subjects completed PhenX Toolkit and other self-report measures of socioeconomic factors, the 10-item Perceived Stress Scale, Kessler Psychological Distress Scale (K6), Fagerstrom Test for Nicotine Dependence (FTND), and the Hooked on Nicotine Checklist (HONC). Moderation analyses using linear regression examined income-related differences in the association between stress and nicotine dependence.ResultsIncome groups were categorized by an annual household income of $50,000 based on visual-inspection of scatter plots of income by nicotine dependence. Compared to higher income smokers, lower income smokers had significantly higher mean levels of nicotine dependence on the FTND [3.74 vs. 4.79, p < 0.001], perceived stress [15.63 vs. 17.95, p = 0.004], and psychological distress [5.30 vs. 6.86, p = 0.001], respectively. There were interaction effects, such that lower income smokers had a strong, positive associations between FTND and perceived stress (B = −0.11, CI = −0.17 to −0.04, p = 0.002) and psychological distress (B = −0.13, CI = −0.25 to −0.02, p = 0.022) whereas no association was found in higher income smokers. No significant moderation effects were found for the HONC or when income groups were categorized by U.S. federal poverty level.ConclusionsThe results highlight that the relationship between increasing stress and FTND was found in lower but not higher income groups. Future research should examine socioeconomic, environmental and psychosocial factors that may facilitate increased smoking during stress-induced craving.     

Cannabis use among women of reproductive age in the United States: 2002–2017

BackgroundIn this study of cannabis use in large nationally representative samples of United States (US) women aged 12–44 years, we evaluate variation by pregnancy month and by trimester. We also evaluate cannabis dependence, which might explain why some women continue using cannabis during pregnancy.MethodsLarge nationally representative samples drawn for the US National Surveys on Drug Use and Health included 12–44-year-old women asked about pregnancy month, cannabis use, and cannabis dependence (n = 381,199). For this research, we produced month-specific estimates across four-time intervals (2002–2005, 2006–2009, 2010–2013, 2014–2017).ResultsOverall from 2002 to 2017, estimates for non-pregnant women and for pregnant women in Trimester 1 indicate 7%–8% had used cannabis at least once in the 30 days prior to assessment. For pregnancy Month 1, the corresponding estimate is 11%, double Month 3 estimate of 5%. This degree of month-to-month variation is not seen for pregnant women in Trimesters 2 and 3, for whom estimates are 3% and 2%, respectively. Among women using cannabis during pregnancy, an estimated 19% have cannabis dependence, versus an expected value of 13% among non-pregnant women (p < .05).ConclusionEvidence of a possibly ameliorative pregnancy-associated reduction of cannabis use prevalence was seen by Month 3 during pregnancy. Cannabis dependence may help account for cannabis use early during pregnancy. Identification and outreach to reproductive age women with cannabis dependence might decrease prenatal cannabis exposure.     

Sexual and gender minority young adults' smoking characteristics: Assessing differences by sexual orientation and gender identity

IntroductionSexual and gender minority (SGM) young adults have higher smoking prevalence than their non-SGM peers. Less is known about differences in smoking characteristics within the SGM community.MethodsParticipants were SGM young adult smokers age 18–25 (N = 165, M age = 21.8) enrolled in a clinical trial of the Put It Out Project, a Facebook smoking cessation intervention for SGM young adults. Analyses tested differences between 1) sexual orientation groups, and 2) gender identity groups, on the following smoking characteristics: cigarettes/day, daily smoker (yes/no), social smoker (yes/no), years of smoking, number of close friends who smoke (out of 5), age of initiation, age began smoking regularly, time to first cigarette (30 min or less/>30 min), lifetime quit attempts, past-year quit attempts, and stage of change for quitting smoking (precontemplation, contemplation, preparation).ResultsParticipants were 56% bi/pansexual, 18% gay, 18% lesbian, 8% other (e.g., asexual, queer). The gender identity of the sample was 52% cisgender, 18% transgender, 30% gender non-binary. Lesbian women began smoking at an older age (M = 18.0, SD = 2.0) than “other” sexual orientation participants (M = 15.7, SD = 2.2), p < .05. Transgender participants smoked the most cigarettes per day (M = 11.3, SD = 6.7), followed by cisgender (M = 8.1, SD = 5.6), then non-binary (M = 5.7, SD = 3.5) participants (p < .001; pairwise comparisons p's < 0.05). No other constructs differed by sexual orientation or gender.ConclusionsSmoking characteristics were mostly similar across subgroups of young adult SGM smokers; however, transgender individuals were heavier smokers.     

Emotion dysregulation and cigarette dependence,perceptions of quitting,and problems during quit attempts among Spanish-speaking Latinx adult smokers

Latinx smokers in the United States (U.S.) represent an understudied health disparities group in terms of tobacco use. Despite scientific interest to elucidate individual difference risk factors for smoking, there is limited understanding of how emotional dysregulation relates to smoking outcomes among Spanish-speaking Latinx smokers. The purpose of the present investigation was therefore to explore emotion dysregulation in relation to cigarette dependence, perceived barriers for quitting, and severity of problems experienced during prior quit attempts. Participants were 363 Spanish-speaking Latinx daily smokers (58.7% female, M_age = 33.3 years, SD = 9.81). Results indicated that emotion dysregulation was significantly related to cigarette dependence, perceived barriers for quitting, and problems experienced during past quit attempts. Notably, the effects accounted for 7% to 15% of variance and were evident after adjusting for gender, income, education, number of medical conditions, depression symptoms, non-alcohol drug use, and alcohol consumption. The findings provide novel evidence that emotion dysregulation may represent an important individual difference factor for better understanding smoking-related outcomes among Latinx smokers and supports the need for greater attention to this affective vulnerability during smoking cessation treatment.     

Anthropometric and body composition changes in smokers vs abstainers following an exercise-aided pharmacotherapy smoking cessation trial for women

IntroductionPost-cessation weight gain contributes to smoking relapse, especially for women. Furthermore, excess weight in the form of android or visceral fat is associated with metabolic health problems. For this study, a secondary analysis was conducted in 2015 to determine whether quitting status, achieved through a 14 week supervised exercise-aided nicotine replacement therapy (NRT) cessation program [Getting Physical on Cigarette Trial-2009 to 2013; Prapavessis, et al., 2016], affects anthropometric and body composition parameters in female smokers (N = 413, M age = 42.39 years).MethodsAnthropometric (weight and BMI) and body composition (% total body fat, % android fat, lean mass and visceral fat) indices were assessed at baseline and end of treatment. Smoking status was confirmed weekly from expired breath carbon monoxide. Adherence to exercise and NRT patch was calculated from the number of exercise sessions attended and patches worn to the number of exercise sessions offered and patches supplied, respectively.ResultsFactorial (smoking status) ANCOVAs controlling for baseline anthropometric and body composition parameters as well as adherence to exercise and NRT revealed significant differences in weight (p = .033; ɳ_p² = 0.017) and BMI (p = .020; ɳ_p² = 0.020) at week 14. This equated to abstainers weighing 1.26 kg more and having a 0.52 higher BMI than smokers. No significant differences were found for any of the body composition parameters at week 14 (ɳ_p² range from 0.001–0.007).ConclusionsAbstainers gain modest weight compared to smokers. This weight gain is related to increases in lean mass and not total, android, or visceral fat.     

Short-Term Fluctuations in Motivation to Quit Smoking in a Sample of Smokers in Hawaii

Background: Despite its potential for usefulness in informing the development of smoking cessation interventions, short-term fluctuations in motivation to quit is a relatively understudied topic. Objectives: To assess the prevalence of smokers’ day-to-day fluctuations in motivation to quit, and to assess associations of day-to-day fluctuations in motivation to quit with several established cessation-related variables. Methods: A cross-sectional survey was administered to smokers in Hawaii (N = 1,567). To assess short-term fluctuations in motivation to quit smoking, participants were asked to respond “True” or “False” to the statement: “My motivation to quit smoking changes from one day to the next.” Other items measured desire to quit smoking, intention to quit, confidence in quitting, cigarette dependence, and other cessation-related variables. Results: “My motivation to quit smoking changes from one day to the next” was endorsed as true by 64.7% of smokers, and false by 35.3%. Analyses revealed that smokers who indicated fluctuating motivation were significantly more interested in quitting as compared to smokers without fluctuations. Fluctuations in motivation to quit also were associated with greater confidence in quitting, lesser cigarette dependence, and more recent quitting activity (all p < .01). Conclusions: Day-to-day fluctuations in motivation to quit are common. Day-to-day fluctuations in motivation to quit are strongly associated with higher motivation to quit, greater confidence in future quitting, and other positive cessation-relevant trends.     

Pain intensity and tobacco smoking among Latinx Spanish-speaking adult smokers

Some research suggests that pain intensity is greater among Latinx persons compared to non-Hispanic-Whites, and that the experience of more intense pain among this group is related to poorer mental health and impairment. Yet, the degree to which pain-smoking relations generalize to Latinx smokers is unknown. The present study tested whether past-month pain intensity among adult Latinx smokers was related to cigarette dependence, perceived barriers for quitting, and problems experienced during past quit attempts. Participants were 363 Spanish-speaking Latinx daily smokers (58.7% female, M_age = 33.3 years, SD = 9.81). Consistent with prediction, current pain intensity was significantly related to greater cigarette dependence, perceived barriers for quitting, and problems experienced during past quit attempts. These novel data provide preliminary evidence that individual differences in the intensity of experienced pain in the past month is related to a range of clinically-significant smoking variables among a large sample of Latinx smokers. The findings suggest that pain intensity may be important to Latinx smokers, a group that often showcases pain-related disparities compared to other racial/ethnic groups.     

Young adults report increased pleasure from using e-cigarettes and smoking tobacco cigarettes when drinking alcohol

BackgroundCigarettes share a high rate of co-use with alcohol, particularly among young adults. Studies have demonstrated greater perceived pleasure from smoking cigarettes when drinking alcohol. However, little is known about co-use of electronic cigarettes (e-cigs) and alcohol. The current study sought to compare extent of use and perceived pleasure from cigarettes and e-cigs when drinking alcohol.MethodsYoung adult bar patrons in California cities (San Diego, Los Angeles, and San Francisco) were recruited in 2015–16 using randomized time-location sampling. Participants completed cross-sectional surveys in bars, reporting the percent of cigarette smoking/e-cig use that occurred under the influence of alcohol, and reported if pleasure from smoking cigarettes/using e-cigs changed when drinking alcohol. Analyses are limited to participants reporting current (past 30-day) use of cigarettes, e-cigs, and alcohol (N = 269; M age = 24.1; 40.1% female, 36.1% Non-Hispanic White).ResultsParticipants reported a greater percentage of cigarette smoking compared to e-cig use under the influence of alcohol (cigarettes M = 63.6%; e-cigs M = 46.7%; p < .001). Participants also reported increased pleasure both from smoking cigarettes (M = 3.9; [compared to midpoint of scale 3 - “no change”] p < .001) and using e-cigs (M = 3.3; p < .001) when drinking alcohol. The increase in pleasure was more pronounced for cigarettes compared to e-cigs (p < .001).ConclusionsDrinking alcohol is associated with increases in perceived rewarding effects of both cigarettes and e-cigs and thus may increase their abuse liability. This effect may be stronger for cigarettes, which could be an important barrier to switching completely from smoking cigarettes to using e-cigs, or quitting both entirely.     

Relationship of autonomy social support to quitting motivation in diverse smokers

Background: Research examining relationships between social support and smoking cessation has paid little attention to non-treatment seeking smokers and not considered the role of autonomy support for fostering quitting motivation. This study examined if autonomy support received from family and friends was associated with quitting motivation and making a quit attempt among diverse smokers with varying levels of quitting motivation. Demographic characteristics associated with autonomy support were explored.

Methods: Participants (N?=?312) responded to advertisements seeking smokers ‘not quite ready to quit,’ and were primarily Black, low-income and unemployed. Most (255) of them were enrolled in a clinical trial of smoking cessation induction strategies (treatment sample). An additional 57 not meeting the trial eligibility criteria of low quitting motivation were enrolled for baseline assessments only. Participants completed baseline measures of autonomy support received from friends and autonomous quitting motivation. In the treatment sample, quit attempts were assessed at six-month follow-up.

Results: Females reported higher levels than males of autonomy support from friends (p?=?0.003). Participants with a high school diploma/GED reported higher levels of support from family (p?<?0.001) and friends (p?=?0.014) than those with less education or a college/graduate degree. Both family (p?=?0.007) and friends (p?=?0.004) autonomy support scores were significantly, albeit weakly, associated with autonomous quitting motivation. Autonomy support was not associated with making a quit attempt.

Conclusions: Support from family and friends may promote autonomous reasons to quit among diverse smokers. Research is needed to assess the role of social support in the pre-quitting phases among racial and socio-economically diverse populations.

Electronic cigarette awareness and use among adults in Hong Kong

IntroductionElectronic cigarettes (e-cigarettes) have gained popularity rapidly in the Western world but data in the East are scarce. We examined the awareness and ever use of e-cigarettes, and reasons for e-cigarette use in a probability sample of adults in Hong Kong.MethodsCross-sectional data were collected in 2014 from Chinese adults aged 15–65 in Hong Kong (819 never smokers, 800 former smokers, 800 current smokers) via computer-assisted telephone interviews (response rate: 73.8%). Analysis was limited to a subset of 809 respondents (i.e., 357 never smokers, 269 former smokers, 183 current smokers) who were randomly selected to answer questions on e-cigarettes. Chi-square analyses compared e-cigarette awareness and ever use by gender, age, education, and cigarette smoking status. Multivariable logistic regression examined if e-cigarette awareness was associated with demographic variables and cigarette smoking status.Results75.4% of adults had heard of e-cigarettes, and 2.3% reported having used e-cigarettes. Greater awareness was associated with male gender and higher education. Ever use of e-cigarettes was higher among males (3.6%, p = .03), younger adults (aged 15–29, 5.2%, p = .002), and current cigarette smokers (11.8%, p < .001). Common reasons for using e-cigarettes were curiosity (47.4%), the stylish product design (25.8%), and quitting smoking (13.6%).ConclusionsAwareness of e-cigarettes was widespread in Hong Kong. Although the use of e-cigarettes was low, its relation with younger age and current smoking is of concern. Health surveillance of e-cigarette use is needed. Interventions should target young adults and cigarette smokers, and address the marketing messages, especially the effect of e-cigarettes on smoking cessation.     

Reasons for quitting smoking in young adult cigarette smokers

BackgroundAlthough most young adult smokers want to quit smoking, few can do so successfully. Increased understanding of reasons to quit in this age group could help tailor interventions, but few studies document reasons to quit in young adults or examine reasons to quit by smoker characteristics.MethodsIn 2011–12, 311 current smokers (age 22–28, M = 24.1; 48.9% male, 51.1% female; 50.4% daily smokers) from the Nicotine Dependence in Teens Study completed the Adolescent Reasons for Quitting scale. We assessed differences in the importance of 15 reasons to quit by sex, education, smoking frequency, quit attempt in the past year, perceived difficulty in quitting, and motivation to quit. We also examined differences between participants who discounted the importance of long-term health risks and those who acknowledged such risks.ResultsConcerns about getting sick or still smoking when older were considered very important by > 70% of participants. Median scores were higher among daily smokers, those who had tried to quit or who expressed difficulty quitting, and those with strong motivation to quit. Discounters (14.5% of participants) were primarily nondaily, low-consumption smokers. Their Fagerström Test for Nicotine Dependence scores did not differ from non-discounters', and 11% (vs. 35.7% of non-discounters) were ICD-10 tobacco dependent.ConclusionsNovel smoking cessation interventions are needed to help young adult smokers quit by capitalizing on their health concerns. Discounters may need educational intervention to better understand the impact of even “light” smoking on their health before or in conjunction with quit interventions.     

Polytobacco use and risk perceptions among young adults: The potential role of habituation to risk

IntroductionPolytobacco use and experimentation is common among young adults. Additional research is needed to determine how these patterns of use impact perceptions of tobacco-related harm and risk. The current study examined whether a relationship exists between an increased number of tobacco products used and decreases in perceptions of harmfulness and health risk.MethodParticipants (N = 792) completed a survey assessing current/lifetime tobacco use, perceived absolute harmfulness of tobacco/nicotine products and perceived health risk of smoking. For some analyses, participants were grouped by polytobacco use status.ResultsAmong participants who ever tried a tobacco product, a greater number of products tried was associated with lower perceptions of harm (all p < .05). For e-cigarettes and hookah, nonusers rated tobacco products as more harmful compared to single product, dual, and poly users (all p < .05). Number of products tried predicted perceived harmfulness above and beyond demographic characteristics and polytobacco use status across all products. Similarly, number of products tried predicted perceived health risk above and beyond demographic characteristics and polytobacco use status for both lung cancer and heart disease risk.DiscussionTrying a greater number of tobacco products is associated with lower perceived harmfulness of tobacco products. Prospective studies are needed to determine if experimentation with more tobacco products leads to reductions in perceived risk of tobacco use and subsequent sustained use of tobacco.
