Perceptions of African American Youth and Adults Regarding Tobacco Use-Related Factors in Their Community: A Mixed-Methods Approach in Richmond, Virginia.

INTRODUCTION: The US Food and Drug Administration is poised to restrict the availability of menthol cigarettes and flavored cigars, products disproportionately used by Black/African American (B/AA) individuals. We examined B/AA youth and adult perceptions regarding factors contributing to tobacco use, as well as prevention/cessation resources. METHODS: In 2 mixed-methods studies in Richmond, Virginia, we conducted cross-sectional surveys among youth (n = 201) and adult (n = 212) individuals who were primarily B/AA and reported past 30-day cigar smoking or nontobacco use, followed by focus groups with a subset (youth: n = 30; adults: n = 24). Focus groups were analyzed using a thematic analysis framework, and descriptive survey data provided context to themes. RESULTS: Among focus group participants, 20% of youth and 75% of adults reported current cigar smoking. Six themes emerged across the groups: advertising/brands, sensory experiences, costs, social factors, youth-related factors, and dependence/cessation. Youth and adults perceived cigars as popular; cigar use was attributed to targeted advertising, flavors, affordability, and accessibility. While adults expressed concern regarding youth tobacco use, youth did not perceive tobacco prevention programs as helpful. Adults and youth reported limited access to community tobacco prevention/cessation programs. DISCUSSION: Expanded tobacco prevention and cessation resources for B/AA people who smoke could leverage federal regulatory actions to ban tobacco products targeted toward this group and decrease disparities in tobacco-related morbidity and mortality.

Urban-rural disparities in geographic accessibility to care for people living with HIV.

In the United States, people living with HIV (PLWH) in rural areas fare worse along the HIV care continuum than their urban counterparts; this may be due in part to limited geographic access to care. We estimated drive time to care for PLWH, focusing on urban-rural differences. Adult Medicaid enrollees living with HIV and their usual care clinicians were identified using administrative claims data from 14 states (Medicaid Analytic eXtract, 2009-2012). We used geographic network analysis to calculate one-way drive time from the enrollee's ZIP code tabulation area centroid to their clinician's practice address, then examined urban-rural differences using bivariate statistics. Additional analyses included altering the definition of rurality; examining subsamples based on the state of residence, services received, and clinician specialty; and adjusting for individual and county characteristics. Across n = 49,596 PLWH, median drive time to care was 12.8 min (interquartile range 26.3). Median drive time for rural enrollees (43.6 (82.0)) was nearly four times longer than for urban enrollees (11.9 (20.6) minutes, p < 0.0001), and drive times exceeded one hour for 38% of rural enrollees (versus 12% of urban, p < 0.0001). Urban-rural disparities remained in all additional analyses. Sustained efforts to circumvent limited geographic access to care are critical for rural areas.

Smoking status and racial/ethnic disparities in youth exposure to tobacco advertising.

Tobacco advertising exposure increases tobacco use among youth. Data were from a largely racial and ethnic minority sample (60% non-Hispanic (NH) Black/African American) of youth (13-18 years) who were nonsmokers susceptible to future tobacco use (n = 686) or current cigarette smokers (n = 674). Regression models tested associations between tobacco advertisement exposure and smoking status, and determined demographic correlates. Nearly all youth recalled seeing a tobacco advertisement (98%), which was associated with smoking (OR = 1.12; 95% CI = 1.08-1.15). Racial minority youth had higher exposure to tobacco advertising. Policies restricting advertisements for all tobacco products are essential for prevention efforts and may help decrease tobacco-related health disparities.

Human Immunodeficiency Virus-Experienced Clinician Workforce Capacity: Urban-Rural Disparities in the Southern United States.

BACKGROUND: Human immunodeficiency virus (HIV)-experienced clinicians are critical for positive outcomes along the HIV care continuum. However, access to HIV-experienced clinicians may be limited, particularly in nonmetropolitan areas, where HIV is increasing. We examined HIV clinician workforce capacity, focusing on HIV experience and urban-rural differences, in the Southern United States. METHODS: We used Medicaid claims and clinician characteristics (Medicaid Analytic eXtract [MAX] and MAX Provider Characteristics, 2009-2011), county-level rurality (National Center for Health Statistics, 2013), and diagnosed HIV cases (AIDSVu, 2014) to assess HIV clinician capacity in 14 states. We assumed that clinicians accepting Medicaid approximated the region's HIV workforce, since three-quarters of clinicians accept Medicaid insurance. HIV-experienced clinicians were defined as those providing care to ≥ 10 Medicaid enrollees over 3 years. We assessed HIV workforce capacity with county-level clinician-to-population ratios, using Wilcoxon-Mann-Whitney tests to compare urban-rural differences. RESULTS: We identified 5012 clinicians providing routine HIV management, of whom 28% were HIV-experienced. HIV-experienced clinicians were more likely to specialize in infectious diseases (48% vs 6%, P < .001) and practice in urban areas (96% vs 83%, P < .001) compared to non-HIV-experienced clinicians. The median clinician-to-population ratio for all HIV clinicians was 13.3 (interquartile range, 38.0), with no significant urban-rural differences. When considering HIV experience, 81% of counties had no HIV-experienced clinicians, and rural counties generally had fewer HIV-experienced clinicians per 1000 diagnosed HIV cases (P < .001). CONCLUSIONS: Significant urban-rural disparities exist in HIV-experienced workforce capacity for communities in the Southern United States. Policies to improve equity in access to HIV-experienced clinical care for both urban and rural communities are urgently needed.

Structural barriers to comprehensive, coordinated HIV care: geographic accessibility in the US South.

Structural barriers to HIV care are particularly challenging in the US South, which has higher HIV diagnosis rates, poverty, uninsurance, HIV stigma, and rurality, and fewer comprehensive public health programs versus other US regions. Focusing on one structural barrier, we examined geographic accessibility to comprehensive, coordinated HIV care (HIVCCC) in the US South. We integrated publicly available data to study travel time to HIVCCC in 16 Southern states and District of Columbia. We geocoded HIVCCC service locations and estimated drive time between the population-weighted county centroid and closest HIVCCC facility. We evaluated drive time in aggregate, and by county-level HIV prevalence quintile, urbanicity, and race/ethnicity. Optimal drive time was ≤30 min, a common primary care accessibility threshold. We identified 228 service locations providing HIVCCC across 1422 Southern counties, with median drive time to care of 70 min (IQR 64 min). For 368 counties in the top HIV prevalence quintile, median drive time is 50 min (IQR 61 min), exceeding 60 min in over one-third of these counties. Among counties in the top HIV prevalence quintile, drive time to care is six-folder higher for rural versus super-urban counties. Counties in the top HIV prevalence quintiles for non-Hispanic Blacks and for Hispanics have >50% longer drive time to care versus for non-Hispanic Whites. Including another potential care source-publicly-funded health centers serving low-income populations-could double the number of high-HIV burden counties with drive time ≤30 min, representing nearly 35,000 additional people living with HIV with accessible HIVCCC. Geographic accessibility to HIVCCC is inadequate in the US South, even in high HIV burden areas, and geographic and racial/ethnic disparities exist. Structural factors, such as geographic accessibility to care, may drive disparities in health outcomes. Further research on programmatic policies, and evidence-based alternative HIV care delivery models improving access to care, is critical.

Comprehensive Ryan White Assistance and Human Immunodeficiency Virus Clinical Outcomes: Retention in Care and Viral Suppression in a Medicaid Nonexpansion State.

Background: Knowledge gaps remain about how the Ryan White human immunodeficiency virus (HIV)/AIDS Program (RW) contributes to health outcomes. We examined the association between different RW service classes and retention in care (RiC) or viral suppression (VS). Methods: We identified Virginians engaged in any HIV care between 1 January and 31 December 2014. RW beneficiaries were classified by receipt of ≥1 service from 3 classes: Core medical, Support, and insurance and/or direct medication assistance through the AIDS Drug Assistance Program (ADAP). Receipt of all RW classes was defined as comprehensive assistance. We used multivariable logistic regression to compare the odds of RiC and of VS by comprehensive assistance and by RW classes alone and in combination. Results: Among 13104 individuals, 58% received any RW service and 17% comprehensive assistance. Comprehensive assistance is significantly associated with RiC (adjusted odds ratio [aOR], 8.8 [95% confidence interval {CI}, 7.2-10.8]) and viral suppression (aOR, 3.3 [95% CI, 2.9-3.8]). Receiving any 2 RW classes or Core alone is significantly associated with RiC and VS, with the strength of association decreasing as the number of classes decreases. Recipients of Support alone are significantly less likely to have VS (aOR, 0.75 [95% CI, .59-.96]). For ADAP recipients also receiving Core and/or Support, insurance assistance is significantly associated with VS compared to receiving direct medication only (aOR, 1.6 [95% CI, 1.3-1.9]); this relationship is not significant for those who receive ADAP alone. Conclusions: Receiving more classes of RW-funded services is associated with improved HIV outcomes. For some populations with insurance, RW-funded services may still be required for optimal health outcomes.

Drinking, Cigarette Smoking, and Employment Among American College Freshmen at a Four-Year University.

BACKGROUND: For American college students, alcohol and cigarette use are important health concerns, and employment concurrent with school attendance is on the rise. Given the lifelong importance of employment and substance use trajectories begun in college, parsing out the relationship between the two is meaningful. OBJECTIVES: This study's purpose is to determine whether employment during college is associated with substance use. METHODS: Cross-sectional associations between employment (work hours, earnings) and substance use (drinking frequency, drinking quantity, smoking frequency) were estimated using partial proportional odds models in a sample of N = 1457 freshmen attending a large, public 4-year university in 2011, after accounting for demographics, personality, social environment, and parental influences. RESULTS: Working 10 more hours and earning $50 more per week as a freshman had modest positive associations with higher smoking frequency and with moderate drinking frequency and quantity prior to adjustment. After adjustment, work hours remained modestly associated with moderate drinking frequency and quantity. No adjusted associations were found among employment measures and smoking or between weekly earnings and drinking frequency. Different relationships emerged for moderate versus heavy alcohol use frequency and quantity. CONCLUSIONS: Both employment and substance use are commonplace among college freshmen. After extensive controls for potential confounders, the relationship between the two appears modest. Employment may yet play a role in college student substance use, but work hours and earnings are likely only small parts of a larger web of influences on drinking and smoking.

All in the Family? A Twin-Based Analysis of Associations Between Occupational Risk Factors, Drinking, and Tobacco Use in Employed Men.

BACKGROUND: Employment-related substance use can negatively affect both workplace and worker. Relationships between workplace characteristics and substance use may be explained by genetic and environmental effects; this research uses a co-twin control (discordant twin) design to disentangle these influences. METHODS: This study compared population-level to discordant twin pair relationships to analyze the genetic and environmental influences of work-related risks on substance use in N = 2,138 dizygotic and monozygotic male twins from the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders. Negative binomial and logistic regressions were fit to predict differences in the frequency of drinking, typical and maximum number of drinks, the number of cigarettes per day, and any binge drinking or any tobacco use across occupation, work hours, job strain, problems with coworkers, and perceived job insecurity. RESULTS: In population-level analyses, several work-related variables were associated with substance use. The population-level associations of occupation with typical and maximum drinks per day and of problems with coworkers to binge drinking were not significant at the twin level. At both the population and discordant twin levels, only higher occupational status was associated with a lower likelihood of regular tobacco use (odds ratio 0.44, 95% confidence interval 0.21, 0.94). CONCLUSIONS: Variation in genes and shared environment appears to account for many of the population-level relationships between work-related stressors and substance use. Work stressors may not be the most fruitful intervention point when aiming to reduce alcohol or tobacco use, although men in certain high-stress occupations may be at greater risk for substance use.

Clinical outcomes of HIV care delivery models in the US: a systematic review.

With over 1 million people living with HIV, the US faces national challenges in HIV care delivery due to an inadequate HIV specialist workforce and the increasing role of non-communicable chronic diseases in driving morbidity and mortality in HIV-infected patients. Alternative HIV care delivery models, which include substantial roles for advanced practitioners and/or coordination between specialty and primary care settings in managing HIV-infected patients, may address these needs. We aimed to systematically review the evidence on patient-level HIV-specific and primary care health outcomes for HIV-infected adults receiving outpatient care across HIV care delivery models. We identified randomized trials and observational studies from bibliographic and other databases through March 2016. Eligible studies met pre-specified eligibility criteria including on care delivery models and patient-level health outcomes. We considered all available evidence, including non-experimental studies, and evaluated studies for risk of bias. We identified 3605 studies, of which 13 met eligibility criteria. Of the 13 eligible studies, the majority evaluated specialty-based care (9 studies). Across all studies and care delivery models, eligible studies primarily reported mortality and antiretroviral use, with specialty-based care associated with mortality reductions at the clinician and practice levels and with increased antiretroviral initiation or use at the clinician level but not the practice level. Limited and heterogeneous outcomes were reported for other patient-level HIV-specific outcomes (e.g., viral suppression) as well as for primary care health outcomes across all care delivery models. No studies addressed chronic care outcomes related to aging. Limited evidence was available across geographic settings and key populations. As re-design of care delivery in the US continues to evolve, better understanding of patient-level HIV-related and primary care health outcomes, especially across different staffing models and among different patient populations and geographic locations, is urgently needed to improve HIV disease management.

Expanding on cross-price elasticity: Understanding tobacco product demand and substitution from the cross-price purchase task.

We examine whether cigarettes serve as substitutes for electronic nicotine delivery systems (ENDS) among ENDS users and demonstrate methodological extensions of data from a cross-price purchase task to inform policies and interventions. During a clinical laboratory study, n = 19 exclusive ENDS users and n = 17 dual cigarette/ENDS users completed a cross-price purchase task with cigarettes available at a fixed price while prices of own-brand ENDS increased. We estimated cross-price elasticity using linear models to examine substitutability. We defined five additional outcomes: nonzero cross-price intensity (purchasing cigarettes if ENDS were free), constant null demand (not purchasing cigarettes at any ENDS price), cross-product crossover point (first price where participants purchased more cigarettes than ENDS), dual-demand score (percentage of prices where both products were purchased), and dual-use break point (minimum relative price to force complete substitution). The cross-price elasticity results indicated that cigarettes could serve as substitutes for ENDS among ENDS users on average, but this average effect masked substantial heterogeneity in profiles of demand (here, a measure of the drug's reinforcement potential). Policies and regulations that increase ENDS prices appear unlikely to steer most exclusive ENDS users toward cigarette use, as most would not purchase cigarettes at any ENDS price, but they could prompt some dual users to substitute cigarettes completely while others remain dual users. This heterogeneity in consumer responses suggests additional indices of cross-product demand are useful to characterize the anticipated and unanticipated effects of tobacco price policies more fully.

Assessment of human abuse potential of an unflavored, sucralose-sweetened electronic cigarette in combustible cigarette smokers.

Despite the popularity of electronic cigarettes (ECIGs), limited research has examined the role of sweeteners, independent of other flavors, in shaping ECIG human abuse potential (HAP). This study examined the effects of sucralose and nicotine in unflavored ECIG liquid solutions to provide a basic understanding of the effects of sweeteners on ECIG HAP compared to combustible cigarettes. Individuals who smoked cigarettes daily (N = 14) completed five within-subject, Latin-square ordered study sessions that differed by product used: (a) own-brand combustible cigarettes (OB), (b) 0 mg/mL nicotine, unsweetened liquid, (c) 0 mg/mL nicotine, sucralose-sweetened liquid, (d) 15 mg/mL nicotine, unsweetened liquid, and (e) 15 mg/mL nicotine, sucralose-sweetened liquid. Participants completed subjective questionnaires and behavioral tasks following a 10-puff directed use bout during which puff topography was measured, and blood was sampled for later measurement of plasma nicotine concentration. On average, the OB condition had a greater increase in plasma nicotine concentration and produced more pronounced subjective effects compared to the ECIG conditions. The 15 mg/mL nicotine ECIGs delivered significantly more nicotine and produced greater drug effects and reductions in tobacco abstinence symptoms than the 0 mg/mL nicotine ECIGs. Sucralose-containing solutions increased ECIG product appeal, puff duration, and puff volume during the 10-puff directed bout. Findings revealed greater HAP for OB cigarettes relative to all ECIGs tested and suggest that adding sucralose and nicotine elevates ECIG HAP via different mechanisms; sucralose appears to influence HAP through product appeal, while nicotine influences HAP through drug effects and tobacco/nicotine abstinence symptom suppression.

The electronic nicotine delivery system (ENDS) purchase task: Are results sensitive to price framing?

Extension of the cigarette purchase task (CPT) to electronic nicotine delivery systems (ENDS) is complicated by the heterogeneous nature of this product class, as ambiguity exists regarding the appropriate price-frame (i.e., unit of the product being purchased). We explored correlations between ENDS purchase task (E-CPTs) outcomes featuring two common price-frames: 10 puffs and 1 mL of liquid. Adult exclusive ENDS users (N = 19) and dual users of ENDS and cigarettes (N = 16) completed two own-brand E-CPTs. One E-CPT used "10 puffs" as its price-frame; the other used "1 mL of liquid." Five outcomes were generated for each E-CPT: breakpoint, intensity, Omax, Pmax, and α. Exploratory Factor Analyses (EFA) considered how these outcomes captured latent structures of demand for ENDS. Spearman correlations in E-CPT outcomes assessed within-person variation between price-frames. Analyses also considered whether correlations differed by user group. E-CPT outcomes were highly correlated across price-frames (ρs > 0.57, ps < .001), and EFA revealed little difference in how outcomes from the tasks loaded onto two latent structures of demand ("Persistence" and "Amplitude") reported in the previous literature. The magnitude of correlations for E-CPT outcomes tended to be higher for exclusive ENDS users than for dual users. Participant responses to purchase task outcomes were similar across two E-CPT price-frames. Using "10 puffs" as a price-frame may be a generalizable approach among heterogenous groups of ENDS users, but researchers should consider their target population and structure the E-CPT to reflect participants' knowledge and purchasing behaviors.

Brief Report: Physician Reimbursement and Retention in HIV Care: Racial Disparities in the US South.

BACKGROUND: Retention in HIV care remains a national challenge. Addressing structural barriers to care may improve retention. We examined the association between physician reimbursement and retention in HIV care, including racial differences. METHODS: We integrated person-level administrative claims (Medicaid Analytic eXtract, 2008-2012), state Medicaid-to-Medicare physician fee ratios (Urban Institute, 2008, 2012), and county characteristics for 15 Southern states plus District of Columbia. The fee ratio is a standardized measure of physician reimbursement capturing Medicaid relative to Medicare physician reimbursement across states. Generalized estimating equations assessed the association between the fee ratio and retention (≥2 care markers ≥90 days apart in a calendar year). Stratified analyses assessed racial differences. We varied definitions of retention, subsamples, and definitions of the fee ratio, including the fee ratio at parity. RESULTS: The sample included 55,237 adult Medicaid enrollees with HIV (179,002 enrollee years). Enrollees were retained in HIV care for 76.6% of their enrollment years, with retention lower among non-Hispanic Black (76.1%) versus non-Hispanic White enrollees (81.3%, P < 0.001). A 10-percentage point increase in physician reimbursement was associated with 4% increased odds of retention (adjusted odds ratio 1.04, 95% confidence interval: 1.01 to 1.07). In stratified analyses, the positive, significant association occurred among non-Hispanic Black (1.08, 1.05-1.12) but not non-Hispanic White enrollees (0.87, 0.74-1.02). Findings were robust across sensitivity analyses. When the fee ratio reached parity, predicted retention increased significantly overall and for non-Hispanic Black enrollees. CONCLUSION: Higher physician reimbursement may improve retention in HIV care, particularly among non-Hispanic Black individuals, and could be a mechanism to promote health equity.

Acute effects of flavored Black and mild cigars among young adult cigarette smokers.

The U.S. Food and Drug Administration proposed new product standards that would ban characterizing flavors (other than tobacco) in cigars. To inform this regulatory action, we compared physiological effects, use behavior, and subjective effects of four popular cigar flavors in cigar-naïve young adult cigarette smokers. Across five laboratory visits, participants (n = 25) used and evaluated own brand (OB) cigarettes or Black & Mild cigars (original, wine, apple, and cream flavors). Linear mixed models tested differences in saliva nicotine, exhaled carbon monoxide (CO), heart rate (HR), blood pressure (BP), puff topography, and subjective effects (p < .05). Compared to all cigars, OB resulted in higher nicotine boost (953 vs. < 300 ng/ml) and lower CO boost (4 vs. 8-9 ppm). Nicotine boost for original cigars (283 ng/ml) was significantly higher than wine (190 ng/ml). All products significantly increased HR/BP relative to baseline, but across time wine and apple cigars were associated with significantly lower HR than OB and BP effects varied. Relative to OB, participants took approximately 0.5 s longer puffs for all cigars and took significantly larger puffs (+ 21%-24%) of original, wine, and apple cigars. OB was rated more positively than all cigars, which had similar subjective effects. Wine cigars were disliked most and were less effective in reducing tobacco abstinence symptoms than OB; cream cigars were harsher and had stronger flavor intensity than original. The consistency in toxicant exposure, use behavior, and subjective effects across cigar flavors, including original, highlights the need for product standards to interpret characterizing flavors subject to prohibition broadly.

Nicotine/tobacco use disparities among transgender and gender diverse adults: Findings from wave 4 PATH data.

BACKGROUND: Transgender and Gender Diverse (TGD) populations have current cigarette/e-cigarette/cigar use rates ranging from 32.6% to 39.7%. Importantly, while some studies have reported tobacco use as significantly higher among TGD versus cisgender individuals in multivariate analyses, others have reported no significant differences. The present study used data from wave 4 of the Population Assessment of Tobacco and Health (PATH) study, a large, nationally representative U.S. study, to examine relationships among sociodemographic characteristics, internal and external factors, and tobacco use behaviors, with a focus on TGD individuals. METHODS: Data were from 33,628 adults from the PATH study's wave 4 (collected December 2016-January 2018). Multivariable logistic regression models examined differences in current tobacco use (cigarettes, electronic nicotine products, and cigars) between TGD and cisgender individuals through the replication of previous work using PATH data, as well as evaluating the role of other internal and external factors. RESULTS: TGD individuals were 2-3 times more likely than cisgender individuals to report current nicotine/tobacco use, even after adjustment for potential confounders. TGD individuals tended to have lower income and education and be more likely to endorse a sexual minority identity than their cisgender counterparts; meanwhile, lower income, less education, and lesbian/gay and bisexual identities were significant predictors of nicotine/tobacco use, independent of TGD identity. CONCLUSIONS: Present findings underscore the high rates of nicotine/tobacco use in the TGNC community and emphasize the necessity of TGD-focused research methods and measures, access to quality medical care, and policy aimed at minimizing marginalization and nicotine/tobacco use disparities experienced by TGD communities.

The interaction of nicotine concentration and device power on electronic nicotine delivery system (ENDS) abuse liability among exclusive ENDS users and dual users of ENDS and combustible cigarettes.

Open-system electronic nicotine delivery systems (ENDS) permit modifications to device characteristics such as power, potentially increasing nicotine and toxicant delivery. Limiting liquid nicotine concentration may carry unintended consequences by prompting users to increase device power to increase nicotine delivery. This study examined the abuse liability of ENDS across nicotine concentration and power settings. In a clinical laboratory study, n = 19 exclusive ENDS users and n = 13 dual ENDS/cigarette users, aged 21-55 completed four Latin-square ordered conditions that varied by liquid nicotine concentration (10 mg/ml [low], 30 mg/ml [high]) and device power (15 watts [low], 30 watts [high]), that were followed by a fifth own brand (OB) condition. A progressive ratio task (PRT) using bar presses to earn ENDS puffs was used to assess abuse liability and compare between conditions using mixed effects linear regressions. The low nicotine/high watt condition was associated with a significantly higher number of bar presses and puffs earned relative to the OB ENDS, high nicotine/high watt, and high nicotine/low watt conditions (p < .05). Findings appeared to be driven largely by exclusive ENDS users; most comparisons were not significant among dual users. Participants worked significantly harder for puffs of low nicotine/high watt ENDS, highlighting previous findings that suggest limiting liquid nicotine concentration without addressing power settings may be insufficient to reduce the abuse liability of ENDS.

Behavioral economic assessment of abuse liability for Black & Mild cigar flavors among young adults.

Cigars are available in a variety of flavors that may impact uptake and use, but little is known about how different flavors affect abuse liability. This study used 3 behavioral economic tasks to examine abuse liability of Black & Mild cigars differing in flavor among young adult cigarette smokers. Participants were 25 cigar-naïve young adults (aged 18-25 years) who smoked ≥ 5 cigarettes/day. In 5 Latin square-ordered laboratory visits, participants completed 3 abuse liability tasks (drug purchase task, cross-price purchase task, and multiple-choice procedure) for each of 4 cigar flavors (original, cream, wine, or apple) and own-brand cigarettes. In the drug purchase task, relative to own-brand cigarettes, all cigar flavors were associated with lower abuse liability using most measures (intensity, breakpoint, maximum total tobacco expenditure for 1 day [ps < .05]), although only wine-flavored cigars scored significantly lower using 1 measure (price at maximum total tobacco expenditure for 1 day). When cigars and cigarettes were available concurrently in the cross-price purchase task, all cigar flavors functioned as substitutes for cigarettes. Using the multiple-choice procedure, crossover points for wine- (mean = $0.61) and apple-flavored cigars (mean = $0.71) were significantly lower than own-brand cigarettes (mean = $0.86) and original-flavored cigars (mean = $1.00); no significant differences existed between own-brand cigarettes and original-flavored cigars. Thus, whereas abuse liability may be highest for participants' own-brand cigarette, young adult smokers may be willing to use flavored cigars. Furthermore, abuse liability varies by cigar flavor, with original- and cream-flavored cigars appearing to have the highest abuse liability. Characterizing flavors and flavor additives in cigars represent an important tobacco regulatory target. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

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

AIMS: To examine the effect on adolescents of exposure to different e-cigarette advertisement themes on reported likelihood of purchasing e-cigarettes in a hypothetical scenario. DESIGN: Between-subjects design of four randomly assigned thematic conditions derived from a content analysis of 350 e-cigarette advertisements: general, flavor- and taste-themed, people- and product use-themed or control advertisements for bottled water. SETTING: Virginia, USA. PARTICIPANTS: Of 1360 adolescents (13-18 years old) participating, 1063 had complete data (519 current cigarette smokers, 544 tobacco-susceptible non-smokers). MEASUREMENTS: Participants completed an e-cigarette purchase task, reporting the likelihood of buying an e-cigarette at various prices. Indices of abuse liability included price responsiveness (whether likelihood of purchase decreased with increasing prices) and, among price-responsive adolescents, breakpoint (highest price before definitely would not buy), maximum probability-weighted expenditure (Omax ) and price elasticity (how quickly willingness to purchase decreases as prices increase). Regressions controlled for demographics, prior tobacco ad exposure, tobacco/substance use and sensation-seeking. FINDINGS: Prior advertisement exposure was positively associated with being price-responsive [odds ratio (OR) = 1.12, 95% confidence interval (CI) = 1.03, 1.22; P < 0.05]. Among price-responsive adolescents (n = 579), breakpoints were 58% higher in the flavor- and taste-themed condition (ß = 0.46, 95% CI = <0.01, 0.92) and 75% higher in the people- and product use-themed condition (ß = 0.56, 95% CI = 0.10, 1.03) compared with control (Ps < 0.05). Exposure to people- and product use-themed advertisements was associated with a 60% higher Omax (ß = 0.47, 95% CI = 0.01, 0.93; P < 0.05). The general and people- and product use-themed conditions were associated with 19% (ß = -0.21, 95% CI = -0.38, -0.04) and 21% (ß = -0.24, 95% CI = -0.42, -0.06) lower elasticity, respectively (Ps < 0.05). CONCLUSIONS: E-cigarette advertising exposure may increase reported likelihood of purchasing e-cigarettes, with effects differing by advertisement content. People- and product use-themed e-cigarette advertisements increased reported likelihood of purchasing in price-responsive adolescents.

Assessing the coherence of narratives of traumatic events with latent semantic analysis.

OBJECTIVE: Memories of traumatic events are thought to be less coherent than memories for nontraumatic events, and expressive writing about traumatic events may help create more organized, coherent memories. Investigations of traumatic memories have been hampered by limitations in conceptualizing and measuring memory organization and coherence. The objective of this investigation was to compare the coherence of written narratives of trauma and neutral memories and examine changes in coherence of trauma narratives as a function of repeated expressive writing about the trauma using an atheoretical, computational method for assessing the coherence of text. METHOD: Participants (N = 246) wrote 3 times about either their daily activities (neutral condition) or the most traumatic event of their lives. Latent semantic analysis, a method of calculating meaning from text based on semantic association between words, was used to assess narrative coherence as the average semantic association between contiguous sentences. RESULTS: Neutral narratives were more coherent than trauma narratives overall, but neutral narratives decreased whereas trauma narratives increased in coherence from the first to the final session. CONCLUSIONS: These findings provide evidence that memories for trauma experiences are less coherent than neutral memories and suggest that writing helps to create a more coherent representation of a traumatic event, highlighting a potential mechanism for expressive writing's effects. Results demonstrate the utility of latent semantic analysis for examining coherence of memories of traumatic events. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Effects of Electronic Cigarette Liquid Flavors and Modified Risk Messages on Perceptions and Subjective Effects of E-Cigarettes.

Understanding how two characteristics-flavors and modified risk messages-affect perceptions and subjective effects of electronic cigarettes (e-cigarettes) can inform tobacco control efforts. In two within-subjects studies ( N = 17 and N = 19), the effects of e-cigarette flavors (tobacco vs. menthol and unflavored vs. cherry) and hypothetical modified risk messages ("reduced harm relative to cigarettes" vs. no message and "reduced carcinogen exposure relative to cigarettes" vs. no message) on cigarette smokers' perceptions of e-cigarettes were measured after participants self-administered condition-specific products (own-brand cigarettes; e-cigarettes). Perceptions/subjective effects were tested using linear mixed-effects regressions. Cigarettes were perceived as most harmful but rated more positively than e-cigarettes ( ps < .05). Cherry and menthol e-cigarettes increased perceived pleasantness, taste, and physical sensations compared with unflavored and tobacco-flavored e-cigarettes, respectively ( ps < .05). Modified risk messages were associated with reduced ratings of aversive effects ( ps < .05) but not harm perceptions. Overall, few perceptions/subjective effects differed by e-cigarette flavor or message. Flavors and messages may have some influence on how smokers experience e-cigarettes.
