Understanding the effectiveness of advertisements about the long-term harms of alcohol and low-risk drinking guidelines: A mediation analysis

RATIONALE

Many people overestimate the amount of alcohol that increases their risk of harm and so may not perceive any need to change their drinking behaviour. Several countries have developed low-risk drinking guidelines, yet awareness of these guidelines remains low. Furthermore, mass media campaigns about alcohol-related harms may have limited impact if people do not perceive their current consumption as potentially harmful. Integrating drinking guidelines into media campaigns about alcohol's harms can concurrently provide drinkers with information about low-risk drinking levels and compelling reasons to comply.

OBJECTIVE

Our aim was to build understanding of the effectiveness of messages about the long-term harms of drinking and low-risk drinking guidelines, by testing the mediating effects of estimates of harmful drinking levels and attitudes towards drinking alcohol on subsequent intentions and behaviours.

METHOD

In an online experiment conducted in 2016, n = 1156 Australian adult monthly drinkers were randomly assigned to view advertisements for non-alcohol products (NON-ALC; control), advertisements featuring long-term harms of alcohol (LTH), or LTH advertisements plus a guideline message (LTH + G). Immediately following exposure, we measured estimates of harmful drinking levels and attitudes towards drinking alcohol. One week later, we measured intentions to drink less and behavioural compliance with the guideline.

RESULTS

Compared to NON-ALC advertisements, exposure to LTH + G advertisements increased (i) the proportion of respondents who correctly estimated harmful drinking levels, which in turn, strengthened intentions to drink less (42% of the total effect was mediated), and (ii) negative attitudes, which in turn, also increased intentions to drink less (35% mediated) and behavioural compliance (24% mediated). Compared to NON-ALC, LTH advertisements increased negative attitudes, which in turn strengthened intentions to drink less (53% mediated).

CONCLUSIONS

When paired with effective alcohol harm reduction television advertisements, messages promoting low-risk drinking guidelines can increase drinkers' intentions to reduce their alcohol consumption and compliance with low-risk drinking guidelines.

Managing dissociative symptoms following the use of esketamine nasal spray: a case report

Patients with treatment-resistant depression (TRD) treated with esketamine nasal spray commonly experience transient symptoms of dissociation. Manifestations of dissociation, such as feelings of detachment from the environment, can cause considerable anxiety for patients. Nonpharmacologic interventions may help clinicians to manage associated anxiety and confusion due to dissociation following administration of esketamine nasal spray. We present the case of a 64-year-old woman with major depressive disorder who participated in a clinical trial evaluating the efficacy and safety of esketamine nasal spray in conjunction with an oral antidepressant for TRD. The patient received flexible doses of esketamine nasal spray (56 or 84 mg) twice weekly for 4 weeks. On treatment day 1, the patient was administered 56 mg of esketamine nasal spray using two nasal spray devices (28 mg per device). Twenty minutes after the first esketamine nasal spray device was administered, the patient experienced a dissociative episode lasting 40 minutes that caused anxiety and confusion. The patient was encouraged to listen to music during treatment sessions, which resulted in notable improvement of her symptoms. Listening to music of choice immediately following esketamine nasal spray administration along with reassurance from staff may help manage confusion and anxiety associated with dissociation.

Australian smokers’ experiences and perceptions of recessed and firm filter cigarettes

Background

While cigarette filter modifications have long been used to increase product appeal and assuage health concerns, tighter marketing restrictions, including plain packaging, have further spurred the growth of filter variants. We explored and assessed experiences and perceptions of smokers who had tried and/or currently use recessed filter cigarettes (RFCs) and firm filter cigarettes (FFCs).

Method

In November 2018, we undertook eight exploratory focus groups of Australian adult factory-made cigarette smokers (total n=56). In July 2019, we surveyed 999 smokers aged 18–69 years to quantify ever and current use of these products and associated beliefs and sensory experiences.

Results

Focus group and survey findings were consistent. Among 988 smokers who had at least tried factory-made cigarettes, 28.9% had tried FFCs and 11.1% currently smoked these, while 36.4% had tried RFCs and 7.5% currently smoked these. Smokers in both studies believed these filters may reduce harm and that FFCs increase appeal. In the survey, 58.9% of RFC triers agreed these hide the filter’s brown stain and 48.9% agreed that RFCs keep harmful substances away from the mouth. Similarly, 58.4% of FFC triers agreed these trap more harmful substances than standard filters. Relative to standard filter cigarettes, more smokers experienced FFCs and RFCs as feeling clean (p=0.03) and more current FFC users experienced these as feeling smooth (p=0.01).

Conclusion

RFCs and FFCs undermine plain packaging legislation, which aims to reduce appeal and minimise misperceptions about the relative harms of different tobacco products. Like other filter modifications, these filter variants should be disallowed.

Comparing responses to public health and industry-funded alcohol harm reduction advertisements: an experimental study

OBJECTIVES

Conduct a head-to-head experimental test of responses to alcohol harm reduction advertisements developed by alcohol industry Social Aspects/Public Relations Organisations (SAPROs) versus those developed by public health (PH) agencies. We hypothesised that, on average, SAPRO advertisements would be less effective at generating motivation (H1) and intentions to reduce alcohol consumption (H2) but more effective at generating positive perceptions of people who drink (H3).

DESIGN

Online experiment with random assignment to condition.

PARTICIPANTS

2923 Australian adult weekly drinkers (49% high-risk drinkers) recruited from an opt-in online panel.

INTERVENTIONS

Participants viewed 3 of 83 advertisements developed by PH agencies (n=2174) or 3 of 28 advertisements developed by SAPROs (n=749).

PRIMARY OUTCOME MEASURES

Participants reported their motivation to reduce the amount of alcohol consumed; behave responsibly and/or not get drunk; and limit their drinking around/never supply to minors, as well as intentions to avoid drinking alcohol completely; reduce the number of drinking occasions; and reduce the amount of alcohol consumed per occasion. Participants also reported their perceptions of people who drink alcohol on six success-related items and four fun-related items.

RESULTS

Compared with drinkers exposed to PH advertisements, those exposed to SAPRO advertisements reported lower motivation to reduce the amount of alcohol consumed (β=-0.091, 95% CI -0.171 to -0.010), and lower odds of intending to avoid alcohol completely (OR=0.77, 0.63 to 0.94) and to reduce the amount of alcohol consumed per occasion (OR=0.82, 0.69 to 0.97). SAPRO advertisements generated more favourable fun-related perceptions of drinkers (β=0.095, 0.013 to 0.177).

CONCLUSIONS

The alcohol harm reduction advertisements produced by alcohol industry SAPROs that were tested in this study were not as effective at generating motivation and intentions to reduce alcohol consumption as those developed by PH organisations. These findings raise questions as to whether SAPROs should play a role in alcohol harm reduction efforts.

Treatment of Vestibular Migraine: A Systematic Review and Meta-analysis

OBJECTIVE

To assess the efficacy of the various therapies used for the prevention of vestibular migraine (VM).

METHODS

Primary studies were identified though PubMed, Scopus, PsycINFO, and Cochrane Library by two independent investigators for articles published through April 2019. The search identified randomized comparison or observational studies pertaining to vestibular migraine treatment. Meta-analysis was performed on pre- and posttreatment Dizziness Handicap Inventory, vertigo frequency, and percentage of perceived improvement.

RESULTS

Literature search identified 13 studies that reported sufficient outcome measures to be included in the analysis. Patients with VM had a mean age of 43.3 years with female-to-male gender ratio of 2.1:1. Classes of therapeutic agents included antiepileptic drugs, calcium channel blockers, tricyclic antidepressants, β-blockers, serotonin and norepinephrine reuptake inhibitors, and vestibular rehabilitation. All treatment options that were analyzed demonstrated improvement in all of the outcome parameters, but due to significant heterogeneity and lack of standardized reporting on outcomes, establishment of preferred treatment modality could not be determined.

CONCLUSIONS

Various treatment modalities have been evaluated for preventative treatment of VM. Physician familiarity, patient comorbidities, and the side-effect profiles of various interventions likely influence the selection of intervention. Future randomized controlled trials with restrictive inclusion criteria and generalizable standardized outcome measures will allow for more robust meta-analyses and for more evidence-based treatment of vestibular migraines.

Association of Treatment Delays With Survival for Patients With Head and Neck Cancer: A Systematic Review

Importance

Delays in the delivery of care for head and neck cancer (HNC) are a key driver of poor oncologic outcomes and thus represent an important therapeutic target.

Objective

To synthesize information about the association between delays in the delivery of care for HNC and oncologic outcomes.

Evidence Review

A systematic review of the English-language literature in PubMed/MEDLINE and Scopus published between January 1, 2007, and February 28, 2018, was performed to identify articles addressing the association between treatment delays and oncologic outcomes for patients with HNC. Articles that were included (1) addressed cancer of the oral cavity, oropharynx, hypopharynx, or larynx; (2) discussed patients treated in 2004 or later; (3) analyzed time of diagnosis to treatment initiation (DTI), time from surgery to the initiation of postoperative radiotherapy, and/or treatment package time (TPT; the time from surgery through the completion of postoperative radiotherapy); (4) included a clear definition of treatment delay; and (5) analyzed the association between the treatment time interval and an oncologic outcome measure. Quality assessment was performed using the Institute of Health Economics Quality Appraisal Checklist for Case Series Studies.

Findings

A total of 18 studies met inclusion criteria and formed the basis of the systematic review. Nine studies used the National Cancer Database and 6 studies were single-institution retrospective reviews. Of the 13 studies assessing DTI, 9 found an association between longer DTI and poorer overall survival; proposed DTI delay thresholds ranged from more than 20 days to 120 days or more. Four of the 5 studies assessing time from surgery to the initiation of postoperative radiotherapy (and all 4 studies assessing guideline-adherent time to postoperative radiotherapy) found an association between a timely progression from surgery to the initiation of postoperative radiotherapy and improved overall or recurrence-free survival. Of the 5 studies examining TPT, 4 found that prolonged TPT correlated with poorer overall survival; proposed thresholds for prolonged TPT ranged from 77 days or more to more than 100 days.

Conclusions and Relevance

Timely care regarding initiation of treatment, postoperative radiotherapy, and TPT is associated with survival for patients with HNC, although significant heterogeneity exists for defining delayed DTI and TPT. Further research is required to standardize optimal time goals, identify barriers to timely care for each interval, and design interventions to minimize delays.

Hair Transplantation in Frontal Fibrosing Alopecia and Lichen Planopilaris: A Systematic Review

OBJECTIVE

Evolving hair transplantation (HT) techniques have offered new possibilities for hair restoration. However, the role of HT in patients with frontal fibrosing alopecia (FFA) and lichen planopilaris (LPP) remains unclear. This study aims to evaluate the outcomes and temporal relationship of HT in this population.

METHODS

A literature search of three databases was conducted. We reviewed 1) literature reporting outcomes of patients with LPP or FFA who received HT, and 2) studies reporting the development of LPP or FFA resulting from HT.

RESULTS

Thirteen articles included 42 patients that provided data for evaluation. Fifteen patients had previously been diagnosed with FFA or LPP, and the remaining 27 patients developed disease after undergoing HT. Seven patients with FFA and eight patients with LPP received HT, with a mean sustained disease remission of 2.69 years prior to HT. In total, two of seven (29%) patients with FFA and five of eight (75%) patients with LPP experienced positive HT results over a follow-up period of 8-72 months. Interestingly, 27 patients without evidence of previous disease developed FFA or LPP following HT after a median duration of 16 months.

CONCLUSIONS

HT for LPP and FFA is feasible but results may be less favorable compared to HT for other causes. Outcomes may be more favorable for LPP than FFA but this was not statistically significant and evidence is very limited. FFA and LPP can also develop following HT in patients without previous evidence of disease.

Designing Effective Testimonial Pictorial Warning Labels for Tobacco Products

Warning labels on tobacco products sometimes feature images and stories of real people whose health has been affected by smoking. We examined effects of some of the design elements that may contribute to the effectiveness of these testimonial pictorial warning labels (PWLs). Beginning with a testimonial PWL that contained an image of a person and a basic warning statement (e.g., "Smoking can kill you"), we examined the impact of adding: (a) text detailing the person's name, age and health status (identifiers); and (b) explanatory statements that elaborated on the basic warning using a testimonial or non-testimonial message. In an online experiment, 1255 adult smokers in the United States were randomly assigned to one of six experimental conditions (2 [identifier: none/identifier] × 3 [explanatory statement: none/non-testimonial/testimonial]), or a control condition (text only warning labels that currently appear on packs in the United States). In each condition, participants were exposed to multiple labels each focused on a different health effect. Effectiveness was assessed using emotional responses, engagement and behavioral intentions measured immediately post-exposure, and quit attempts measured at five-week follow up. Testimonial PWLs were more effective than the text only labels. However, there was little evidence that adding identifiers or the explanatory statements enhanced effectiveness; rather, there was some evidence that testimonial explanatory statements reduced effectiveness. These findings suggest that the most effective design for testimonial PWLs may be to combine a basic warning statement with an image of a real person, without any additional textual components.

Effectiveness of the IBCLC: Have we Made an Impact on the Care of Breastfeeding Families Over the Past Decade?

BACKGROUND

International Board Certified Lactation Consultants (IBCLCs) have been in existence for over 3 decades, are currently represented in 110 countries, and have the only internationally recognized certification to provide safe and evidenced-based care for breastfeeding women and their infants.

RESEARCH AIM

To review the literature about the efficacy of IBCLCs on breastfeeding outcomes as well as studies that have examined the effectiveness of the IBCLC's role.

METHODS

The design was a scoping review of the literature and critical analysis using PRISMA guidelines of existing studies published from 2008-2019. Qualitative and quantitative studies were reviewed.

RESULTS

Twelve (N =12) studies met inclusion criteria. Seven themes emerged in the analysis including studies of the role of IBCLCs in resident physician education; IBCLC's role in breastfeeding interventions and the management of breastfeeding problems; the impact of IBCLCs in inpatient and outpatient settings; and the impact of geographic access to IBCLCs on breastfeeding rates. Certification of and ongoing professional development of IBCLCs are also discussed.

CONCLUSION

In this scoping review of existing literature assessing the effectiveness of IBCLCs in promoting and supporting breastfeeding, it is clear that IBCLCs play a positive role in supporting breastfeeding throughout the world. However, there are certain limitations that must be addressed. Recommendations for future research and clinical practice are discussed in the context of present limitations to breastfeeding expertise and support.

Factors associated with intentions to use e-cigarettes among Australian young adult non-smokers

INTRODUCTION AND AIMS

A growing body of evidence suggests e-cigarette use increases the risk of conventional cigarette use. Assessing the factors associated with intentions to use e-cigarettes can inform programs designed to minimise uptake, potentially assisting in preventing a new population of smokers. This study developed and tested a model assessing the importance of various factors that may be associated with intentions to use e-cigarettes among young adults who have never used e-cigarettes or tobacco cigarettes.

DESIGN AND METHODS

A web-panel provider recruited 429 Australian 18- to 25-year-olds who had never used e-cigarettes or smoked tobacco cigarettes (56% female, mean age = 21.17 years). Various individual and social factors were assessed as potential direct and indirect predictors of e-cigarette use intentions.

RESULTS

The developed model provided an excellent fit to the data and accounted for 49% of the variance in use intentions. Males had greater intentions to use e-cigarettes compared to females (β = -0.13). Having a greater number of friends who smoke tobacco cigarettes (β = 0.11) and curiosity about e-cigarette use (β = 0.58) were also directly associated with greater use intentions. Positive expectancies about e-cigarettes (β = 0.14), having family members who use e-cigarettes (β = 0.11), and having friends who smoke tobacco cigarettes (β = 0.07) were indirectly associated with intentions via curiosity.

DISCUSSION AND CONCLUSIONS

Curiosity about e-cigarette use was strongly associated with use intentions. Aspects of the social environment were also important. Further research is needed to identify effective means of challenging positive e-cigarette expectancies given these were found to be strongly associated with intentions via curiosity.

Hardening or softening? An observational study of changes to the prevalence of hardening indicators in Victoria, Australia, 2001-2016

BACKGROUND

The hardening hypothesis predicts that as smoking prevalence declines, remaining smokers will be more heavily addicted to nicotine and/or less interested in quitting. We tested this hypothesis in a population exposed to a comprehensive tobacco control programme over a 16-year period.

METHODS

Annual cross-sectional surveys randomly sampled adults (aged 26+) in the state of Victoria, Australia, between 2001 and 2016. Until 2010, participants were recruited through random digit dialling to landline telephones; from 2011, sampling frames also included mobile phones. Logistic regressions assessed changes over time in the prevalence of smoking and each hardening indicator; additional models examined interactions by sex, age, education and socioeconomic status.

RESULTS

Smoking prevalence declined significantly between 2001 and 2016 (20.1%-13.0%), as did the prevalence of seven hardening indicators: daily smoking, heavy consumption, no quit attempt in the past 5 years or past 12 months, no intention to quit in the next 6 months or next 30 days, and happiness to keep smoking. In addition, the proportion of smokers defined as 'hardcore' decreased from 17.2% to 9.1%. On the whole, hardening indicators decreased to a similar extent among demographic subgroups.

CONCLUSIONS

These results are inconsistent with the hardening hypothesis. Rather, they suggest that a comprehensive tobacco control programme that combines provision of cessation support to individual smokers with implementation of population-level interventions to drive all smokers towards quitting, can successfully reduce both smoking prevalence and levels of dependence and desire to keep smoking among the remaining population of smokers.

Observed smoking and tobacco pack display in Australian outdoor cafés 2 years after implementation of plain packaging

Background

Implementation of tobacco plain packaging (PP) in Australia in December 2012 was associated with significant reductions in the percentage of patrons at outdoor cafés observed to be displaying tobacco packs and actively smoking, immediately post-implementation and 1 year later. This study examines whether these positive effects were sustained through to 2 years post-PP.

Methods

An observational study conducted at cafés, restaurants and bars with outdoor seating in Melbourne, Australia documented the number of: patrons; patrons actively smoking; tobacco packs on display; orientation and type of displayed packs and whether or not children were present. Data were collected pre-PP (2012), early post-PP (2013), 1 year post-PP (2014) and 2 years post-PP (2015). Multilevel Poisson regressions analyzed changes in each outcome, adjusting for important covariates.

Results

Overall, positive effects of PP implementation on tobacco pack display and active smoking were not fully sustained through to 2 years post-PP for the total sample. Interactions between phase and the presence of children indicated that pack display and active smoking were lower in all post-implementation phases (compared with pre-PP) at venues where children were present but not at venues where children were not present.

Conclusions

Children at outdoor cafés were still being exposed to less tobacco packaging and active smoking, 2 years after implementation of the packaging changes. More regular refreshment of graphic health warnings is likely to be required to sustain these effects, and to reduce pack display behaviour at venues with no children.

Validating the Hornik & Woolf approach to choosing media campaign themes: Do promising beliefs predict behavior change in a longitudinal study?

Hornik and Woolf (1999) proposed using cross-sectional survey data to prioritize beliefs to address with communication campaign messages. The empirical component of the approach combines evidence of (1) association of beliefs with intentions and (2) current level of beliefs to calculate a 'percentage to gain' as the potential promise of a belief. However, the method relies on cross-sectional data; its conclusions are open to challenge. Here, a panel study assesses whether the calculated promise of a belief actually predicts future behavior change. A nationally representative sample of 3,204 U.S. youth and young adults were interviewed twice, six months apart. Sixteen beliefs about the benefits and costs of smoking cigarettes are compared with regard to their percentage to gain (calculated from cross-sectional data) and their ability to account for subsequent cigarette use. A belief's cross-sectional percentage to gain is substantially associated with its ability to predict subsequent behavior change (r=.53, p<.05).

Critical care usage after major gastrointestinal and liver surgery: a prospective, multicentre observational study

BACKGROUND

Patient selection for critical care admission must balance patient safety with optimal resource allocation. This study aimed to determine the relationship between critical care admission, and postoperative mortality after abdominal surgery.

METHODS

This prespecified secondary analysis of a multicentre, prospective, observational study included consecutive patients enrolled in the DISCOVER study from UK and Republic of Ireland undergoing major gastrointestinal and liver surgery between October and December 2014. The primary outcome was 30-day mortality. Multivariate logistic regression was used to explore associations between critical care admission (planned and unplanned) and mortality, and inter-centre variation in critical care admission after emergency laparotomy.

RESULTS

Of 4529 patients included, 37.8% (n=1713) underwent planned critical care admissions from theatre. Some 3.1% (n=86/2816) admitted to ward-level care subsequently underwent unplanned critical care admission. Overall 30-day mortality was 2.9% (n=133/4519), and the risk-adjusted association between 30-day mortality and critical care admission was higher in unplanned [odds ratio (OR): 8.65, 95% confidence interval (CI): 3.51-19.97) than planned admissions (OR: 2.32, 95% CI: 1.43-3.85). Some 26.7% of patients (n=1210/4529) underwent emergency laparotomies. After adjustment, 49.3% (95% CI: 46.8-51.9%, P<0.001) were predicted to have planned critical care admissions, with 7% (n=10/145) of centres outside the 95% CI.

CONCLUSIONS

After risk adjustment, no 30-day survival benefit was identified for either planned or unplanned postoperative admissions to critical care within this cohort. This likely represents appropriate admission of the highest-risk patients. Planned admissions in selected, intermediate-risk patients may present a strategy to mitigate the risk of unplanned admission. Substantial inter-centre variation exists in planned critical care admissions after emergency laparotomies.

Anti-smoking social norms are associated with increased cessation behaviours among lower and higher socioeconomic status smokers: A population-based cohort study

BACKGROUND

Social denormalisation of smoking can provide an environment that helps smokers to quit. This study examined which of three measures of anti-smoking social norms have the greatest influence on quitting-related cognitions and behaviours, and if this influence differs according to socioeconomic status (SES).

METHODS

The Victorian Tracking Survey measured social norms among 1,348 (n(weighted) = 1,373) Australian adult smokers (aged 18-59) between 2012 and 2014, who were followed-up one week later. Weighted logistic regression analyses examined prospective associations of baseline subjective (family and friends' disapproval of smoking), injunctive (feeling embarrassed about being a smoker) and descriptive norms (living with someone who tried to quit in the past 12 months), with quitting-related cognitions and behaviours at follow-up. Data were weighted to account for telephony status (landline or mobile phone), sex and age. Analyses were adjusted for demographic characteristics, addiction level, tobacco control policies and quitting-related outcomes measured at baseline. Differences in associations between lower and higher SES smokers (based on educational attainment and area-based disadvantage) were examined through interaction terms and stratified analyses.

RESULTS

Sixty-four percent of participants (n(weighted) = 872) perceived disapproval from family and friends, 31% (n(weighted) = 419) felt embarrassed to be a smoker, and 11% (n(weighted) = 155) lived with a recent quitter. All three norms were associated with having set a firm date to quit in the next month and with engaging in smoking limiting behaviours. Embarrassment was also associated with an increased likelihood of talking about quitting and with making a quit attempt. Associations were mostly comparable for lower and higher SES smokers, with no significant negative rebound effects overall or among subgroups.

CONCLUSIONS

These findings indicate close others' disapproval and feelings of embarrassment most strongly motivate smokers to try to quit. If tobacco control policies or media campaigns further denormalise smoking, there should be no reason for concern that such denormalisation undermines cessation behaviours.

Antismoking Social Norms Increase Cessation Behaviours Among Lower and Higher SES Smokers: An Australian Population-Based Study

Background: Disapproval of smoking from close others, observation of others' quitting activity and denormalisation of smoking in the broader community can provide an environment that helps smokers to quit. However, it remains unclear which social norms have the greatest influence, and if there is a similar impact on quitting-related cognitions and behaviors among lower and higher socioeconomic status (SES) smokers. Aim: This study sought to examine the influence on quitting-related cognitions and behaviors of a variety of social norms: subjective (perceived disapproval of smoking among close family and friends); internalized injunctive (feeling embarrassed about being a smoker); and close descriptive norms (living in a household with someone who, successfully or unsuccessfully, tried to quit in the past 12 months). Methods: A telephone survey was conducted among 1454 Australian adult smokers between 2012 and 2014 who were followed-up ∼1 week after the baseline interview. Logistic regression analyses examined prospective associations of baseline social norms with quitting-related cognitions and behaviors at follow-up. Analyses were adjusted for baseline demographic characteristics, addiction level, tobacco control policies (cost increases, plain packaging implementation and mass media campaign exposure) and quitting-related outcomes measured at baseline. Differences in associations between lower and higher SES smokers (based on educational attainment and area-based disadvantage) were examined through interaction terms and stratified analyses. Results: Sixty-three percent of participants perceived disapproval from family and friends, 30% felt embarrassed to be a smoker, and 12% lived with a recent quitter. Baseline disapproval, embarrassment and household quitting activity were each associated with having quitting as a high priority and with setting a firm date to quit in the next month. Both disapproval and embarrassment also predicted engaging in behaviors to limit smoking, and only embarrassment was associated with increased likelihood to talk about quitting with family or friends and to make a quit attempt. No associations were found between social norms and being highly confident to quit and seeking help to quit. Associations were mostly comparable for lower and higher SES smokers, with no significant negative effects of social norms on quitting thoughts and behaviors overall or among subgroups. Conclusion: Within the strong tobacco control environment in Australia, smokers from lower and higher SES groups who perceive that their family and friends disapprove of their smoking, feel embarrassed to be a smoker and/or who live in a household with a recent quitter are more likely to prioritize quitting and intend to quit soon. These findings also indicate that the internalized injunctive social norm (i.e., feeling embarrassed) was the strongest predictor of smokers' quitting related behaviors, including making a quit attempt.

Differences in use of electronic nicotine delivery systems by smoking status and demographic characteristics among Australian young adults

ISSUE ADDRESSED

Electronic nicotine delivery systems (ENDS) continue to grow in popularity, particularly among young adults. Understanding by whom various ENDS are being used and why within this population segment can assist the development of appropriate interventions targeting those most vulnerable to use and inform policy decisions in this area. Accordingly, this study assessed the demographic characteristics associated with ENDS use among Australian young adults, and reasons for current e-cigarette use.

METHODS

An online survey was administered to 1116 Australians aged 18-25 years (59% female).

RESULTS

Smokers were more likely than non-smokers to report (a) ever use of ENDS (67% vs 28%), (b) ever use of an e-cigarette (64% vs 24%), e-cigar (17% vs 8%) or e-hookah (15% vs 8%) and (c) current use of e-cigarettes (19% vs 6%). Male smokers were more likely than female smokers to be current e-cigarette users. The most common reason for current e-cigarette use was enjoyment.

CONCLUSIONS

Young male adults appear to be particularly vulnerable to becoming regular e-cigarette users. This demographic group may need to be a primary focus of prevention and intervention efforts. Contrary to popular belief, smoking cessation was not a primary reason for e-cigarette use. SO WHAT?: Greater efforts are needed to educate young adults on the harms associated with ENDS use, especially if use is being driven by the perception that they are a harmless means of amusement. Maintaining existing regulations limiting the accessibility of these products is crucial to ensuring widespread use is minimised.

E-cigarette product preferences among Australian young adult e-cigarette users

OBJECTIVE

To assess preferences for e-cigarettes containing nicotine and flavourings among Australian young adult e-cigarette users.

METHODS

An online survey was administered to 1,116 young adults (18-25 years), 104 of whom had used an e-cigarette in the last 30 days and were the focus of this study. Among users, 53% also smoked tobacco cigarettes, 27% were non-smokers and 20% had never smoked.

RESULTS

Nearly two-thirds (64%) of e-cigarette users preferred nicotine-containing e-cigarettes (71% of smokers, 56% of non-smokers, 55% of never smokers). The vast majority (89%) preferred flavoured e-cigarettes (92% of smokers, 82% of non-smokers, 95% of never smokers), with fruit flavours the most popular.

CONCLUSIONS

E-cigarettes containing nicotine and flavourings were popular among users of these devices in this sample of young adults. Implications for public health: Previous research has documented potential harms associated with e-liquid additives, flavourings, and nicotine. The present results showing strong preferences for nicotine and flavourings among the sampled e-cigarette users suggest that: i) flavourings in e-liquids should be regulated; and ii) existing prohibitions on the unauthorised supply of liquid nicotine should be better enforced. Population-wide monitoring of the use of e-cigarettes with different product characteristics is also warranted.

Immediate effects on adult drinkers of exposure to alcohol harm reduction advertisements with and without drinking guideline messages: experimental study

AIMS

To compare the immediate effects on drinkers of television advertisements focusing upon short- versus long-term harms with and without low-risk drinking guidelines.

DESIGN

Between-participants on-line experiment, with random assignment to view: (a) alcohol product advertisements (ALC control); (b) advertisements unrelated to alcohol (NON-ALC control); (c) advertisements featuring short-term harms (STH) of alcohol; (d) advertisements featuring STH plus a STH guideline (STH+G); (e) advertisements featuring long-term harms (LTH); or (f) advertisements featuring LTH plus a LTH guideline (LTH+G).

SETTING

Australia, 2016.

PARTICIPANTS

A total of 3718 drinkers aged 18-64 years (48.5% male).

MEASUREMENTS

Post-exposure likelihood that participants provided a correct estimate of drinking levels associated with short- and long-term harms; post-exposure intentions to avoid alcohol or reduce consumption.

FINDINGS

After exposure to STH+G or LTH+G advertisements, participants were more likely to estimate correctly rather than overestimate drinking levels associated with harm, compared with those exposed to STH (P < 0.001) and LTH advertisements without guidelines, respectively (P = 0.019) and ALC control (STH+G, P < 0.001; LTH+G, P < 0.001) and NON-ALC control conditions (STH+G, P < 0.001; LTH+G, P = 0.011). Drinkers exposed to STH conditions were more likely to intend to reduce next-week alcohol consumption than those exposed to ALC control (both P < 0.001) and NON-ALC control conditions (STH, P = 0.001; STH+G, P < 0.001); a similar pattern was observed for intentions to avoid alcohol. Drinkers exposed to LTH conditions were also more likely than drinkers exposed to ALC or NON-ALC controls to intend to avoid and reduce alcohol in the next week. Additionally, drinkers exposed to LTH+G were more likely to intend to reduce drinking than those exposed to LTH advertisements without guidelines (P = 0.022). Response patterns for low- and high-risk drinkers by condition were similar.

CONCLUSIONS

Alcohol harm television advertisements increase intentions to reduce alcohol consumption among both low- and high-risk drinkers. The addition of low-risk drinking guidelines can enhance these effects for advertisements featuring long-term harms and improve estimates of both short- and long-term harmful drinking levels.

Fear, Sadness and Hope: Which Emotions Maximize Impact of Anti-Tobacco Mass Media Advertisements among Lower and Higher SES Groups?

Emotive anti-tobacco advertisements can increase quitting. Discrete emotion theories suggest evoking fear may be more effective than sadness; less research has focused on hope. A weekly cross-sectional survey of smokers and recent quitters (N = 7683) measured past-month quit attempts. The main predictor was level of exposure to four different types of anti-tobacco advertisements broadcast in the two months prior to quit attempts: advertisements predominantly evoking fear, sadness, hope, or evoking multiple negative emotions (i.e., fear, guilt, and/or sadness). Greater exposure to fear-evoking advertisements (OR = 2.16, p < .01) increased odds of making a quit attempt and showed similar effectiveness among those in lower and higher SES areas. Greater exposure to advertisements evoking multiple negative emotions increased quit attempts (OR = 1.70, p < .01), but interactions indicated this was driven by those in lower SES, but not higher SES areas. Greater exposure to hope-evoking advertisements enhanced effects of fear-evoking advertisements among those in higher SES, but not lower SES areas. Findings suggest to be maximally effective across the whole population avoid messages evoking sadness and use messages eliciting fear. If the aim is to specifically motivate those living in lower SES areas where smoking rates are higher, multiple negative emotion messages, but not hope-evoking messages, may also be effective.
