Racial/Ethnic Discrimination and Cardiometabolic Diseases: A Systematic Review

INTRODUCTION

Racial discrimination has been identified as a risk factor for cardiometabolic diseases, the leading cause of morbidity and mortality among racial/ethnic minority groups; however, there is no synthesis of current knowledge on the association between discrimination and cardiometabolic diseases. The objective of this systematic review was to summarize evidence linking racial/ethnic discrimination and cardiometabolic diseases.

METHODS

The review was conducted based on studies identified via electronic searches of 5 databases (PubMed, Google Scholar, WorldWideScience.org, ResearchGate and Microsoft Academic) using terms related to discrimination and cardiometabolic disease.

RESULTS

Of the 123 eligible studies included in the review, 87 were cross-sectional, 25 longitudinal, 8 quasi-experimental, 2 randomized controlled trials and 1 case-control. Cardiometabolic disease outcomes discussed were hypertension (n = 46), cardiovascular disease (n = 40), obesity (n = 12), diabetes (n = 11), metabolic syndrome (n = 9), and chronic kidney disease (n = 5). Although a variety of discrimination measures was employed across the studies, the Everyday Discrimination Scale was used most often (32.5%). African Americans/Blacks were the most frequently studied racial/ethnic group (53.1%), and American Indians the least (0.02%). Significant associations between racial/ethnic discrimination and cardiometabolic disease were found in 73.2% of the studies.

DISCUSSION

Racial/ethnic discrimination is positively associated with increased risk of cardiometabolic disease and higher levels of cardiometabolic biomarkers. Identifying racial/ethnic discrimination as a potential key contributor to the health inequities associated with cardiometabolic diseases is important for addressing the significant burden borne by racial/ethnic minorities.

Psychological Distress and Cannabis Vaping Among U.S. Adolescents

INTRODUCTION

Cannabis vaping has become increasingly popular among adolescents in recent years. However, research examining mental health determinants of cannabis vaping is scant. This study investigated the relationship between psychological distress and cannabis vaping among a nationally representative sample of U.S. adolescents.

METHODS

Data are from the cross-sectional 2022 National Youth Tobacco Survey, restricted to adolescents ages 11-18 (n=22,202). Psychological distress was categorized as normal, mild, moderate, and severe according to the Patient Health Questionnaire for Depression and Anxiety-4. Cannabis vaping was defined as any use in the past 30 days. To estimate the association between psychological distress and cannabis vaping, logistic regression was performed adjusted for age, biological sex, race/ethnicity, sexual orientation, school grades, family smoking/vaping, nicotine vaping, other tobacco use, and blunt use. Analyses were conducted in 2023.

RESULTS

Nearly 8% of adolescents vaped cannabis in the past 30 days, and 25.6% reported moderate or severe psychological distress. Mild, moderate, and severe psychological distress were associated with cannabis vaping in the unadjusted model. In the adjusted model, the odds of cannabis vaping were higher among adolescents who had severe psychological distress (OR: 1.46, 95% CI: 1.09-1.96), compared to adolescents with no distress. Older age, poor grades, family smoking/vaping, nicotine vaping, other tobacco use, and blunt use were also associated with cannabis vaping.

CONCLUSIONS

Severe psychological distress was associated with past 30-day cannabis vaping among U.S. adolescents. Adolescents experiencing psychological distress need to be screened for cannabis vaping to help prevent and reduce use and promote mental health.

Emotion Dysregulation and E-Cigarette Expectancies among College Student E-Cigarette Users

Background: E-cigarette outcome expectancies (i.e., beliefs about the expected consequences of e-cigarette use) are a key factor in motivating use. Emotion regulation difficulties have demonstrated significant associations with outcome expectancies; however, there has yet to be an examination of associations between specific emotion regulation difficulties and specific e-cigarette outcome expectancies, which could serve as targets for intervention efforts. Therefore, the current study sought to examine the unique predictive ability of specific emotion regulation difficulties in terms of e-cigarette outcome expectancies. Methods: Participants were 116 college student e-cigarette users (Mage = 19.72, SD = 1.88; 71.6% female) who completed self-report questionnaires for course credit. Results: Greater difficulties engaging in goal-directed behavior when experiencing negative emotions and fewer difficulties accessing effective emotion regulation strategies were associated with positive reinforcement outcome expectancies. Greater emotion regulation difficulties in general were also associated with negative reinforcement outcome expectancies, though there were no significant individual predictors. Conclusion: These results suggest that greater emotion regulation difficulties are associated with mood-related e-cigarette outcome expectancies, and targeting emotion regulation difficulties, particularly difficulty engaging in goal-directed behavior when upset, may be useful to incorporate into intervention efforts.

Biological Sex as a Moderator of Work Determinants of Health: Implications for Work and Stress

This study examined whether biological sex moderates the relationship between experiences of workplace culture and urinary levels of catecholamines and their metabolites. We conducted a series of regression analyses (predictors: 3-methoxytyramine (3MT), 5-hydroxyindolacetic (5HIAA), and dopamine (DA); outcomes: employee engagement and workplace culture) in a sample of 218 participants. Compared to men, women rated workplace culture less positively (r = -0.210; p < 0.01) and had stronger positive associations with 3MT (r = 0.328; p < 0.001), DA (r = 0.376; p < 0.001), and 5HIAA (r = 0.168; p < 0.01). There was a significant moderation effect between 3MT and sex on employee engagement (b = -1.76 (SE = 0.84); p < 0.01), and 3MT had a positive significant association for men with engagement (p < 0.05); however, there was no significant association for women. Findings suggest that for women, less positive experiences with workplace culture could elevate 3MT, stimulating sympathetic nervous tone and potentially amplifying risks for negative health outcomes. Conversely, men who reported higher employee engagement had higher levels of 3MT, suggesting possible health risks associated with high levels of engagement, rather than lack of engagement. Overall, study findings suggested differential health risks based on biological sex, potentially impacting health risk policy development.

The Green Heart Project: Objectives, Design, and Methods

The Green Heart Project is a community-based trial to evaluate the effects of increasing greenery on urban environment and community health. The study was initiated in 2018 in a low-to-middle-income mixed-race residential area of nearly 28,000 residents in Louisville, KY. The 4 square mile area was surveyed for land use, population characteristics, and greenness, and assigned to 8 paired clusters of demographically- and environmentally matched "target" (T) and adjacent "control" (C), clusters. Ambient levels of ultrafine particles, ozone, oxides of nitrogen, and environmental noise were measured in each cluster. Individual-level data were acquired during in-person exams of 735 participants in Wave 1 (2018-2019) and 545 participants in Wave 2 (2021) to evaluate sociodemographic and psychosocial factors. Blood, urine, nail, and hair samples were collected to evaluate standard cardiovascular risk factors, inflammation, stress, and pollutant exposure. Cardiovascular function was assessed by measuring arterial stiffness and flow-mediated dilation. After completion of Wave 2, more than 8,000 mature, mostly evergreen, trees and shrubs were planted in the T clusters in 2022. Post planting environmental and individual-level data were collected during Wave 3 (2022) from 561 participants. We plan to continue following changes in area characteristics and participant health to evaluate the long-term impact of increasing urban greenery.

Differences in health care provider screening for tobacco use among youth in the United States: The National Youth Tobacco Survey, 2021

OBJECTIVE

Health care providers (HCP) are encouraged to screen youth for tobacco product use as a key step in preventing such use and associated health outcomes. However, recent data examining differences in HCP tobacco screening by sociodemographic characteristics and tobacco use is scant.

METHODS

Data from the 2021 National Youth Tobacco Survey (N = 14,685) were analyzed. Three types of HCP screening were examined: no screening, any e-cigarette use (e-cigarette only, e-cigarette and other tobacco), and non-e-cigarette tobacco product use. Differences by HCP screening were examined using multinomial logistic regression adjusted for age, sex, gender identity, sexual orientation, race/ethnicity, and tobacco use (non-current, sole, dual/poly).

RESULTS

Among the sample, 42.8% were screened for any tobacco use, with 30.6% screened for any e-cigarette use and 12.2% for non-e-cigarette tobacco product use only. Youth who were older (vs. younger) (OR = 5.98, 95% CI: 4.78-7.49) and gay/lesbian (vs. heterosexual) (OR = 1.47, 95% CI: 1.02-2.12) were more likely to be screened for e-cigarette use. Youth who were non-Hispanic Black (vs. non-Hispanic White) were less likely to be screened for e-cigarette use (OR = 0.53, 95% CI: 0.42-0.67) and more likely to be screened for non-e-cigarette tobacco use (OR = 1.34, 95% CI: 1.10-1.63). Current sole tobacco use (vs. non-current use) and dual/poly tobacco use (vs. non-current use) increased the likelihood for HCP screening for e-cigarette use.

CONCLUSIONS

The majority of U.S. youth continue to not be screened for tobacco use by their HCP. Evidence of disparities in tobacco use screening suggest the need for policies and training that promote equity in screening.

Associations between sleep disturbance, physical activity, and anxiety sensitivity among college students during the COVID-19 pandemic

The present study sought to examine associations between anxiety sensitivity and both sleep and physical activity among college students, who are particularly vulnerable to sleep disturbance, decreased physical activity, and the development of psychopathology, especially in the wake of the COVID-19 pandemic. Participants were 683 college students (Mage = 20.33, SD = 3.58; 72% female; 70.3% White) who completed self-report measures online for course credit. Results indicated that after controlling for the effects of age, gender identity, and race, greater sleep disturbance was significantly associated with higher overall anxiety sensitivity (7% unique variance; β = 0.27, t = 6.67, p < .001) as well as its three subdomains (physical concerns: 4% variance; β = 0.21, t = 4.97, p < .001; cognitive concerns: 6% variance; β = 0.25, t = 6.17, p < .001; social concerns: 6% variance; β = 0.26, t = 6.22, p < .001). Additionally, more time spent walking was associated with greater anxiety sensitivity physical concerns (1% variance; β = 0.11, t = 2.52, p = .012) and greater vigorous intensity physical activity was associated with lower anxiety sensitivity social concerns (1% variance; β = -0.13, t = -2.76, p = .006). These findings suggest that sleep problems may be more universally relevant to anxiety sensitivity than physical activity and interventions to promote healthier sleep may be useful for decreasing anxiety sensitivity in college students.

The Role of Perceived Neighborhood Cohesion in the Association between Depressive Symptoms and Cigarette Smoking

BACKGROUND

Greater depression has been linked to increased smoking rates. However, the mechanisms underlying this association are not fully understood. It is possible that high perceived neighborhood cohesion may serve as one such mechanism given its associations with decreased depression and smoking. Having increased levels of depression likely impacts one's perceptions of neighborhood cohesion, which could lead to further increases in depression and a need to manage these symptoms via cigarette smoking. As a first test of this theory, the current study examined the effect of neighborhood cohesion on the association between depressive symptoms and smoking frequency and quantity among past 30-day cigarette smokers.

METHODS

Participants were 201 combustible cigarette smokers (Mage = 48.33, SD = 11.64; 63.2% female; 68.2% White) who completed self-report measures as part of a larger study of environmental influences on cardiac health.

RESULTS

Greater depressive symptoms were associated with lower levels of perceived neighborhood cohesion, and there was a significant indirect effect of greater depressive symptoms on heavier smoking through decreased neighborhood cohesion (b = .07, SE = .04, 95% CI [.003, .15]). There was no significant indirect effect for daily smoking.

CONCLUSION

These results suggest that neighborhood cohesion is an important contextual factor that serves as one explanatory mechanism for the well-established relationship between depression and smoking quantity. Thus, there may be utility in implementing interventions focused on increasing neighborhood cohesion as a way to decrease smoking behavior.

Differences in health care provider advice on abstaining from tobacco use: Findings from the 2020 National Youth Tobacco Survey

BACKGROUND

Health care providers' (HCP) advice on tobacco prevention and cessation is critical in addressing the tobacco use epidemic among adolescents. However, examination of whether receiving advice from HCPs differs by adolescent sociodemographic characteristics and tobacco use is limited.

METHODS

HCP advice to abstain from using tobacco was examined using the 2020 National Youth Tobacco Survey (N = 12,483). Sociodemographic (age, sex, sexual orientation, race/ethnicity, and region) and tobacco use (non-current, sole, dual/poly) differences by HCP advice were evaluated using adjusted logistic regression models.

RESULTS

Among the sample, 37.26% of adolescents received HCP advice to abstain from using tobacco products, and 31.35% received HCP advice to abstain from using e-cigarettes specifically. Adolescents who were non-Hispanic Black (vs. non-Hispanic White) were more likely not to receive HCP advice to abstain from all tobacco products (OR = 1.31, 95% CI: 1.08-1.59). Adolescents who were non-Hispanic Black (vs. non-Hispanic White) (OR = 1.41, 95% CI: 1.16-1.73) or sexual minority (vs. heterosexual) (OR = 1.16, 95% CI: 1.02-1.33) were more likely not to receive HCP advice to abstain from e-cigarettes. Adolescents who were aged 16-18 (vs. aged 9-12) (OR = 0.68, 95% CI: 0.56-0.83) or currently use dual/poly tobacco products (vs. adolescents who do not currently use tobacco) (OR = 0.56, 95% CI: 0.43-0.74) were more likely to receive HCP advice to abstain from using e-cigarettes).

CONCLUSIONS

Many U.S. adolescents do not receive HCP advice to abstain from using tobacco. HCPs should increase tobacco prevention and cessation advice across adolescent groups, particularly racial/ethnic and sexual minorities. HCP training and public health policies that improve delivery of e-cigarette advice to adolescents are essential.

Long-term impact of the COVID-19 pandemic on use behavior and risk perceptions of college student E-cigarette users

Objective: Work examining the long-term impact of the COVID-19 pandemic on e-cigarette use among college students is limited. Therefore, the current study examined differences in college student e-cigarette users' changes in use behavior and risk perceptions as the pandemic continues. Participants: 129 undergraduate current e-cigarette users (Mage = 19.68, SD = 1.85; 72.1% female; 85.3% White). Methods: Participants completed an online survey between October 2020 and April 2021. Results: In terms of changes in frequency of e-cigarette use, 30.5% of participants increased their use and 23.4% decreased their use. Greater e-cigarette dependence and anxiety were associated with increased use. Nearly half of e-cigarette users reported increased motivation to quit, and 32.5% had made at least one quit attempt. Conclusions: A substantial number of students increased their e-cigarette use as a result of the COVID-19 pandemic. Cessation efforts targeting increased anxiety and dependence may be useful in this population.

Harm perceptions of secondhand e-cigarette aerosol among youth in the United States

E-cigarette use among youth remains a public health concern. Although extant literature has examined the perceived harms of cigarette use and secondhand smoke, perceptions of harms associated with secondhand e-cigarette aerosol (SHA) are not well understood. Therefore, we used data from the 2020 U.S. National Youth Tobacco Survey (n = 13,292) in which participants indicated whether SHA caused no harm, little harm, some harm, or a lot of harm. We dichotomized SHA harm perceptions as harmless vs harmful. We included sociodemographics (i.e., age, sex, race/ethnicity, sexual orientation, urbanicity), e-cigarette use characteristics, and SHA exposure as covariates and estimated associations between SHA harm perceptions and each covariate using adjusted logistic regression. Most youth perceived SHA as harmful (87.9 %) compared to harmless (12.1 %). Older youth (vs younger youth) had higher odds of perceiving SHA as harmless, whereas male (vs female) youth had 49 % higher odds (95 % CI: 1.29-1.72) of perceiving SHA as harmless. As the number of days of e-cigarette use in the past 30 days increased (vs non-users), odds of perceiving SHA as harmless increased. Youth exposed to SHA (vs no exposure) in the past 30 days had 35 % higher odds of perceiving SHA as harmless (95 % CI: 1.16-1.57). To conclude, youth SHA harm perceptions varied overall and by sociodemographic characteristics, e-cigarette use, and SHA exposure. Educational campaigns to inform youth of the health risks associated with e-cigarettes and SHA are needed to reduce overall nicotine intake and disparities in nicotine exposure.

The Relationship between Perceptions and Objective Measures of Greenness

Exposure to greenness has been studied through objective measures of remote visualization of greenspace; however, the link to how individuals interpret spaces as green is missing. We examined the associations between three objective greenspace measures with perceptions of greenness. We used a subsample (n = 175; 2018-2019) from an environmental cardiovascular risk cohort to investigate perceptions of residential greenness. Participants completed a 17-item survey electronically. Objective measurements of greenness within 300 m buffer around participants home included normalized difference vegetation index (NDVI), tree canopy and leaf area index. Principal component analysis reduced the perceived greenspaces to three dimensions reflecting natural vegetation, tree cover and built greenspace such as parks. Our results suggest significant positive associations between NDVI, tree canopy and leaf area and perceived greenness reflecting playgrounds; also, associations between tree canopy and perceived greenness reflecting tree cover. These findings indicate that the most used objective greenness measure, NDVI, as well as tree canopy and leaf area may most align with perceptions of parks, whereas tree canopy alone captures individuals' perceptions of tree cover. This highlights the need for research to understand the complexity of green metrics and careful interpretation of data based on the use of subjective or objective measures of greenness.

Community-Based Evaluation of the Associations Between Well-Being and Cardiovascular Disease Risk

Background Although the effects of psychological health and optimism have been extensively investigated, data from community-based cohorts assessing the association between psychological health and cardiovascular disease risk factors are sparse, and the concurrent relationship between subjective well-being and cardiovascular health has not been studied. Methods and Results The current cross-sectional study examined the association between well-being and cardiovascular risk factors among 719 individuals living in a middle- to low-income neighborhood. After adjusting for age, sex, race, body mass index, education, smoking status, and exercise status, we found that higher levels of well-being were significantly associated with lower odds of dyslipidemia (odds ratio [OR], 0.7 [95% CI, 0.55-0.85]) and hypertension (OR, 0.8 [95% CI, 0.63-0.92]). Greater well-being was also significantly associated with lower triglyceride levels (mean difference [M_diff], 7.6 [-14.31 to -0.78]), very low-density lipoprotein (M_diff, 0.9 [-1.71 to -0.16]), total cholesterol to high-density lipoprotein ratio (M_diff, 3.9 [-6.07 to -1.73]), higher high-density lipoprotein levels (M_diff, 1.6 [0.46-2.75]), and lower Framingham Risk Scores (M_diff, -7.1% [-10.84% to -3.16%]). Well-being also moderated the association between age and arterial stiffness. The strongest association between arterial stiffness and age was found for those with the lowest well-being scores; there was no association between age and arterial stiffness at high levels of well-being. Conclusions In a community-based cohort, individuals reporting higher levels of well-being have lower odds of hypertension and dyslipidemia as well as lower rates of age-dependent increase in vascular stiffness.

Public Awareness of and Support for the Use of Wastewater for SARS-CoV-2 Monitoring: A Community Survey in Louisville, Kentucky

The majority of sewer systems in the United States and other countries are operated by public utilities. In the absence of any regulation, the public perception of wastewater monitoring for population health biomarkers is an important consideration for a public utility commission when allocating resources for this purpose. We conducted a survey in August 2021 as part of an ongoing COVID-19 community prevalence study in Louisville/Jefferson County, KY, US. The survey comprised seven questions about wastewater awareness and privacy concerns and was sent to approximately 35 000 households randomly distributed within the county. A total of 1220 adults were involved in the probability sample, and data from 981 respondents were used in the analysis. A total of 2444 adults additionally responded to the convenience sample, and data from 1751 respondents were used in the analysis. The samples were weighted to obtain estimates representative of all adults in the county. Public awareness of tracking the virus that causes COVID-19 in sewers was low. Opinions strongly support the public disclosure of monitoring results. Responses showed that people more strongly supported measurements in the largest areas (>50 000 households), typically representing population levels found in a large community wastewater treatment plant. Those with a history of COVID-19 infection were more likely to support highly localized monitoring. Understanding wastewater surveillance strategies and privacy concern thresholds requires an in-depth and comprehensive analysis of public opinion for continued success and effective public health monitoring.

Workplace Culture and Biomarkers of Health Risk

Workplace culture has been studied for impact on health risk; however, connections with robust biologic markers of health remain to be established. We examined associations between the work environment and urinary levels of catecholamines and their metabolites as biomarkers of sympathetic nervous system activity, indicative of stress. We recruited participants (n = 219; 2018-2019) from a cardiovascular risk cohort to investigate workplace culture, well-being, and stress. Participants completed seven questionnaires. Urine samples were used to measure catecholamines and their metabolites by LC/MS/MS. Pearson correlation and linear regression models were used after adjusting for demographics and creatinine. Participants reporting higher well-being had lower urinary levels of dopamine, serotonin, and 3-methoxytyramine. Participants reporting a more engaged and more positive workplace had lower levels of dopamine and 3-methoxytyramine. Reported workplace isolation was correlated with higher levels of dopamine and 3-methoxytyramine. Given correlations between catecholamines, we used 3-methoxytyramine for linear regression. In fully adjusted models, in environments with a more positive culture, levels of 3-methoxytyramine remained lower (β = -0.065 ± 0.025, p = 0.01) and indicated a positive association between workplace isolation and 3-methoxytyramine (β = 0.064 ± 0.030, p = 0.04). These findings are consistent with an important relationship between workplace environment and sympathetic nervous system activity.

Differences in young adults' perceptions of e-cigarettes by history of use

Objective: The current study examined group differences in college students' views on e-cigarettes in terms of safety, popularity, health risks, social acceptability, efficacy as a cessation aid, and promoting combustible cigarette use. Participants: 337 undergraduates (Mage = 20.84, SD = 3.79; 72.1% female; 68.5% White) divided into three groups: Never Users (n = 178), Ever Users (n = 108), and Current Users (n = 51). Methods: Participants completed questionnaires for course credit. Results: Compared to Ever and Never Users, Current Users believed e-cigarettes were safer, healthier, a useful tool to quit smoking, did not lead to combustible cigarette smoking, and that nicotine was less dangerous. Current Users also were less likely to endorse boosting social image as a motive for use. Conclusions: Public health campaigns could benefit from targeting current users' positive beliefs about e-cigarettes to reduce the prevalence of e-cigarette use among college students.

Readability of online e-cigarette cessation information

INTRODUCTION

Given the growing awareness of the health risks associated with e-cigarettes, many users will access information about how to effectively quit using e-cigarettes, and the internet likely will be a popular source of information. However, little is known about the readability of online e-cigarette cessation information. Therefore, the goal of the current study was to assess the readability of webpage information about e-cigarette cessation.

METHODS

A search of webpages was conducted using the following search terms: vaping addiction, quit vaping, quit Juul, stop vaping, stop Juul, and vaping cessation. The 464 webpages identified were coded for target audience, message valence, and source, and then assessed for reading level with the Flesch-Kincaid Grade Level assessment.

RESULTS

On average, webpage content was written at a 7th grade reading level (Flesch-Kincaid Grade Level Mean=7.34, SD=2.22) and less than 25% of webpages met readability guidelines (i.e. ≤6th grade reading level). There were no differences in readability by target audience, message valence, or webpage source.

CONCLUSIONS

The results suggest that most online content related to e-cigarette cessation is not written at a level that is easily understood by general audiences. Thus, tobacco control advocates should assess the reading level of their messaging to ensure wide accessibility of information.

College Student E-Cigarette Users' Knowledge about E-Cigarettes: Ingredients, Health Risks, Device Modifications, and Information Sources

Although college students represent a growing demographic of e-cigarette users, it is unclear how knowledgeable they are about the product they use. The lack of such knowledge could result in unsafe practices and greater health risks. Therefore, the purpose of the current study was to examine college student e-cigarette users’ knowledge about e-cigarette ingredients and health risks, how often they modify their devices, and whether they utilize reputable sources when searching for information regarding e-cigarettes. The participants were 183 undergraduate e-cigarette users (M_age = 19.98, SD = 1.98; 71.6% female; 85.8% White). Most participants correctly recognized that e-cigarettes increase the risk of cardiovascular disease and lung disease, but fewer than half recognized the increased risk of seizures and depression. Only one-third to one-half of participants correctly identified the toxic compounds commonly found in e-cigarettes, and most indicated that they would consult Google or a friend with questions about e-cigarettes. College student e-cigarette users are well-informed about many health risks associated with e-cigarettes. However, they are relatively unaware of the harmful substances in e-cigarettes and are seeking information from less reliable sources. Targeted public health campaigns educating college students about e-cigarettes, including where to seek reliable information, are needed.

Association between electronic nicotine delivery systems (ENDS) device and E-liquid alterations and flavor use with clinical and EVALI-like symptoms

Studies reporting clinical symptoms related to electronic nicotine delivery systems (ENDS) usage, especially types of devices and e-liquids, are sparse. The sample included 1,432 current ENDS users, ages 18-64, from a nationwide online survey conducted in 2016. ENDS use included device types, nicotine content, flavors, and e-liquid used. Outcomes included any e-cigarette, or vaping, product use-associated lung injury (EVALI)-like symptoms (e.g., cough, shortness of breath, nausea) as well as any clinical symptoms. Of the sample, 50% were female, 23% non-Hispanic (NH) White, 23% NH Black, 54% Hispanic, 18% aged 18-24, 17% LGBTQ, 41% with <$50 K income, 55% 1 + any symptoms, and 33% 1 + any EVALI-like symptoms. Cough and nausea were most prevalent among EVALI-like symptoms (27% and 7.3%, respectively). The proportion having any EVALI-like symptoms was higher in the following groups: younger, Hispanic, current smokers, and current other product users. With multiple adjustments, participants who used refillable devices, varied nicotine content, used flavored products, or made their own e-liquids were more likely to have clinical symptoms than their counterparts. For example, the odds (95% CI) of having 1 + EVALI-like symptoms in participants who used refillable devices with e-liquid pour or e-liquid cartridge replacement were 1.70 (1.13, 2.56) and 1.95 (1.27, 2.99), respectively, compared to the non-refillable group. Use of products (devices and e-liquids) that can be altered and flavored products are associated with higher odds of having clinical symptoms, including EVALI-like symptoms.

Appalachian youth e-cigarette harm perceptions and tobacco use

INTRODUCTION

E-cigarettes are the most popular tobacco product among youth. Although harm perceptions have been linked to youth e-cigarette use, little research focuses on vulnerable populations, such as Appalachian youth. This study examines associations between e-cigarette harm perceptions and tobacco use among a sample of Appalachian youth.

METHODS

Using data from the 2014–2016 Youth Appalachian Tobacco Study (n=1074), distributions of six e-cigarette harm perceptions by tobacco use (never, ever non-e-cigarette, ever e-cigarette) were examined, and multivariable multinomial logistic regression was used.

RESULTS

Nearly one-fourth (23.4%) of the sample were ever e-cigarette users. More e-cigarette users were male (53.4%) and in high school (57.0%). Fewer e-cigarette users strongly agreed that e-cigarettes cause health problems (15.1%), breathing problems (20.3%), and oral health problems (18.7%) and that e-cigarettes are addictive (25.1%), compared to never and non-e-cigarette users. More e-cigarette users strongly agreed (32.3%) that e-cigarettes are healthier alternatives to cigarettes compared to never (24.1%) and non-e-cigarette (25.7%) users. Regression models indicate that e-cigarette users had greater odds of strongly disagreeing with e-cigarettes being harmful or addictive, compared to never users. E-cigarette users had approximately six-fold odds of strongly disagreeing with e-cigarettes causing health problems (OR=6.12; 95% CI: 3.16–11.90) and two times greater odds of disagreeing with e-cigarettes being addictive (OR=2.09; 95% CI: 1.07–4.08) compared to never users.

CONCLUSIONS

Appalachian youth ever e-cigarette users perceive e-cigarettes as less harmful and less addictive compared to never users. Better informing youth, especially youth tobacco users, of the harms associated with e-cigarettes is vital.

The importance of urban planning: Views of greenness and open space is reversely associated with self-reported views and depressive symptoms

INTRODUCTION

Exposure to green spaces is beneficial to mental health in a variety of ways, ranging from stress reduction to increased attentiveness and elevated self-esteem. The impact of views of greenness, as opposed to direct exposure, has been examined, but the association between self-reported views and depressive symptoms is not known. The purpose of this study is to examine the relationship between views of greenness and Patient Health Questionnaire-9 (PHQ-9) score.

METHODS

Questionnaire responses from 191 participants in the Health, Environment, and Action in Louisville (HEAL) study were examined. Univariate statistical analyses included Mann-Whitney U, Kruskal-Wallis, and Spearman rank tests. Inferential statistical analysis was linear regression.

RESULTS

Participant satisfaction with residential greenness was significantly associated with reduced PHQ-9 score (partially adjusted: linear coefficient = -0.42; 95% CI: -0.70 - -0.14; fully adjusted: linear coefficient = -0.21; 95% CI: -0.44 - 0.02). Additionally, being satisfied with local greenness was significantly associated with having views of greenness from home (linear coefficient = 1.97; 95% CI: 1.23-2.68).

CONCLUSIONS

Though views of greenness were not directly associated with depression, satisfaction with local greenness was associated with reduced PHQ-9 score, and having views of greenness from home was crudely associated with increased greenness satisfaction. The findings suggest urban greening interventions that focus on greenness satisfaction may be a strategy to reduce depression. Further research is necessary to better understand these relationships.

The Influence of Friends on Teen Vaping: A Mixed-Methods Approach

Vaping is popular among adolescents. Previous research has explored sources of information and influence on youth vaping, including marketing, ads, family, peers, social media, and the internet. This research endeavors to expand understanding of peer influence. Our hypothesis is that friends’ influence on teen vapers’ first electronic nicotine delivery systems (ENDS) use varies by demographic variables and awareness of ENDS advertising. In August–October 2017, youth (n = 3174) aged 13–18 completed an online survey to quantify ENDS behaviors and attitudes and were invited to participate in follow-up online research in November-December 2017 to probe qualitative context around perceptions and motivations (n = 76). This analysis focused on the ENDS users, defined as having ever tried any ENDS product, from the survey (n = 1549) and the follow-up research (n = 39). Among survey respondents, friends were the most common source of vapers’ first ENDS product (60%). Most survey respondents tried their first ENDS product while “hanging out with friends” (54%). Among follow-up research participants, the theme of socializing was also prominent. ENDS advertising and marketing through social media had a strong association with friend networks; in fact, the odds of friends as source of the first vaping experience were 2 times higher for those who had seen ENDS ads on social media compared with other types of media. The influence of friends is particularly evident among non-Hispanic Whites, Hispanics/Latinos, those living in urban areas, those living in high-income households, those with higher self-esteem, and those who experiment with vaping. These findings support the premise that peer influence is a primary social influencer and reinforcer for vaping. Being included in a popular activity appears to be a strong driving force.

Tobacco Point-of-Sale Influence on U.S. Adult Smokers

INTRODUCTION

Prior research has shown that tobacco companies target point-of-sale (POS) marketing to low-income communities. This research assessed the association between demographic characteristics and venue type with purchasing tobacco products in response to marketing.

METHODS

Using Population Assessment of Tobacco and Health (PATH) Study Wave 1 Adult data, this analysis compared promotion awareness and purchase influence among current smokers.

RESULTS

Tobacco promotions were more likely to be noticed at convenience stores, gas stations, or tobacco stores than at other outlets. Smokers who bought their cigarettes at these outlets were more likely to purchase a brand other than their usual brand because of marketing. Smokers below the poverty level had greater odds than others to have noticed tobacco ads and to indicate purchase influence.

CONCLUSIONS

Point-of-sale marketing is effective in garnering the attention of low-income populations and influencing their tobacco purchases. Enforcing retailers' adherence to regulations is vital.

Time spent outdoors and sleep normality: A preliminary investigation

INTRODUCTION

Sleep deficiency is associated with health risks, and time outdoors is related to health benefits. This study assessed time outdoors and its association with sleep normality.

METHODS

As part of a health study in Louisville, Kentucky, 735 participants completed questionnaires on their health status, behaviors, neighborhoods, and demographics in 2018-2019. The measures included information on sleep, time outdoors, and mental and physical health. Participant characteristics were assessed by dichotomized sleep normality (N=728), and logistic regression (N=709) examined potential associations between time outdoors and sleep.

RESULTS

As time spent outdoors increased from ≤4 hours to >4 - ≤8 hours (OR=1.04; 95% CI: 0.65-1.64) and >8 - ≤12 hours (OR=1.17; 95% CI: 0.63-2.17), odds of normal sleep increased; however, those who spent >12 - ≤16 hours (OR=0.63; 95% CI: 0.31-1.27) or >16 hours (OR=0.83; 95% CI: 0.45-1.53) outdoors had a lower likelihood of normal sleep. No associations between time outdoors and sleep were significant. There was a significant trend of less bodily pain associated with normal sleep (p<0.001) and in the association of depression and sleep, where odds of normal sleep decreased as depression severity increased (p<0.001).

CONCLUSIONS

Consistent with extant literature, findings indicate associations between less pain and increased odds of normal sleep and between higher severity of depression and lower odds of normal sleep. Findings for an overall association between time outdoors and sleep normality were not significant. Future work should seek to better explicate the predictor variables to assess how greenness and activity type shape associations with sleep.

Sex differences in associations between receiving and sharing tobacco-related information and tobacco product use among Appalachian Youth

INTRODUCTION

Given that Appalachian youth tobacco use rates are higher than the US national average, it is important to understand whether sex differences shape associations between receiving and sharing product information and using tobacco.

METHODS

Middle and high school students in rural Appalachia (n=1038) were surveyed about tobacco-related perceptions and behaviors, including ways youth receive and share conventional tobacco-related and e-cigarette-related information. Youth were characterized as tobacco users (i.e. ever or current users of cigarettes, smokeless tobacco, or e-cigarettes) or never users. Descriptive characteristics were compared by tobacco use and sex. Adjusted logistic regression models evaluated associations between communication channels and tobacco use. Models were stratified by sex to examine effect modification.

RESULTS

Approximately one-third of Appalachian youth (33.8%) were tobacco users and use varied by sex (males: 54.4%; females: 45.6%). Male (OR=1.75; 95% CI: 1.18-2.60) and female (OR=2.30; 95% CI: 1.53-3.47) youth who received e-cigarette-related information through friends and family (FF) had higher odds of tobacco use. Additionally, females who received e-cigarette-related information through public displays and digital media had nearly two-fold increased odds of tobacco use. Although sharing conventional tobacco-related and e-cigarette-related information through FF was associated with increased odds of tobacco use among both sexes, these relationships were stronger among females.

CONCLUSIONS

Although specific communication channels were associated with tobacco use, associations involving receiving and sharing e-cigarette information were more pronounced in female tobacco users. Consideration of sex differences in how youth receive and share tobacco-related information may benefit tobacco prevention interventions.

Associations between tobacco use patterns and demographic characteristics of sexual minority and heterosexual youth: Results from a nationwide online survey

INTRODUCTION

Youth are at risk for tobacco use, and previous research has pointed to increased vulnerabilities associated with sexual minority identity. For example, LGB youth have increased odds for using tobacco than their heterosexual peers, and bisexual youth have higher odds of smoking than other sexual identity groups. As new tobacco products proliferate and health risks from dual/poly use grow, increased understanding of tobacco use patterns by sexual minority youth is needed.

METHODS

For 3117 youth, aged 13–18 years, who completed an online questionnaire in 2017 and identified their sexual orientation [minority (e.g. lesbian/gay, bisexual, or pansexual) vs majority (heterosexual)] and gender, we classified current tobacco use into four categories: e-cigarette only, other product only (such as cigarette, cigar, or smokeless tobacco; not an e-cigarette), dual/poly use, and no use. Analyses were conducted separately for male and female participants. Multinomial logistic regression was employed.

RESULTS

Female sexual minority youth had nearly twofold odds of dual/ poly tobacco use (OR=1.95; 95% CI: 1.12–3.40), compared to their heterosexual counterparts. For male youth, sexual minority identification was not significantly associated with dual/poly use. No significant differences were found in sexual minority and heterosexual youth e-cigarette only or other tobacco only use groups. Tobacco use patterns also significantly differed by age, race, place of residence, and parental education level.

CONCLUSIONS

Study findings reveal greater odds of dual/poly tobacco use for female sexual minority youth. Tailored tobacco prevention and cessation programs or interventions are needed for sexual minority youth most at risk of tobacco use, especially multiple product use.

Socioeconomic and Demographic Status and Perceived Health Risks of E-Cigarette Product Contents Among Youth: Results From a National Survey

Background. The prevalence of e-cigarette use among youth is rising and may be associated with perceptions of health risks for these products. We examined how demographic factors and socioeconomic status (SES) are correlated with the perceived health risks of e-cigarette product contents among youth. Method. Data were from a national online survey of youth aged 13 to 18 between August and October 2017, weighted to be representative of the overall U.S. population in age, sex, race/ethnicity, and region. Survey analysis procedures were used. Results. Of 1,549 e-cigarette users and 1,451 never-e-cigarette users, 20.9% were Hispanic, 13.7% Black, 21.7% LGBTQ (lesbian/gay/bisexual/transgender/queer), and 49.3% in low-income families. With adjustment for e-cigarette use status, perceived health risks of nicotine and toxins/chemicals in e-cigarettes significantly differed by gender, race, sexual orientation, and SES (ps < .05). For example, adjusted odds of perceiving harm from nicotine were 60% higher in girls versus boys, 34% lower in non-Hispanic Blacks versus non-Hispanic Whites, 33% lower in urban versus suburban residents, 40% higher in LGBTQ versus straight-identifying individuals, and 28% lower in low-income versus high-income families. Lower parental education level also was associated with children's lower health risk perception of e-cigarette product contents. Conclusions. For youth, the perceived health risks of e-cigarette product contents were associated with demographics, sexual orientation, and SES. The findings may have relevance for developing communication and education strategies addressing specific youth audiences, especially those in vulnerable groups. These strategies could improve awareness among youth concerning the health risks of e-cigarettes, helping to prevent or reduce e-cigarette uptake and continued use.

Tobacco perceptions and practices: User groups and demographic characteristics, Mississippi, USA

INTRODUCTION

Despite decreases in the overall US smoking rate, tobacco use remains more common in some areas and by some groups. Deeper understanding of group differences is needed in order to tailor public health campaigns to the interests, perceptions and experiences of targeted audiences. Although some differences have been identified across African American and Caucasian smokers in the United States, additional insight is needed regarding factors that differentiate these groups. This study examined tobacco-related perceptions and practices, with an emphasis on identifying differences across African American and Caucasian smokers. Toward this goal, we examined key demographic variables of race and age, and tobacco use characteristics.

METHODS

The sample consisted of 284 people from the Jackson, Mississippi area who participated in focus groups and completed surveys addressing a variety of tobacco-related topics, including knowledge and perceptions of products as well as use and health information seeking behavior. The selection criteria and recruitment approach ensured a balance across race (black, white), age (18-34, >35 years), sex, and cigarette smoking status (current, former, never). Statistical analyses were performed using SAS (v.9.4).

RESULTS

Differences were observed across demographic subgroups regarding type and pattern of tobacco products used (e.g. mentholated, markers of nicotine dependence, hookah). Differences in preferred sources of health information based on age as well as perceptions of risk as a function of age, smoking status and race were also noted. Exposure to secondhand smoke and perceptions of its risks, quitting efforts and cessation methods differed by race.

CONCLUSIONS

Study findings suggest key differences across important subgroups. Knowledge of such differences has the potential to improve strategic public health messaging, allowing health campaigns to more effectively prevent tobacco product uptake as well as promote interest in quitting tobacco.

Sociodemographic differences in single, dual, and poly tobacco use among Appalachian youth

INTRODUCTION

Patterns of youth tobacco use, including use of multiple products, have likely shifted as e-cigarettes have grown in popularity. However, there is limited understanding of dual and poly tobacco use and the associated disparities, especially among Appalachian youth.

METHODS

We analyzed Youth Appalachian Tobacco Study data (n=1116) to estimate prevalence of current (past-30 day) cigarette, e-cigarette, and smokeless tobacco use by gender, race/ethnicity, age, school type, state, smartphone use, and number of household tobacco users. We created a pattern of tobacco use variable (i.e. never, former, single, dual, poly) based on all possible combinations of the included products. Using multivariable multinomial logistic regression (outcome reference: never use), we evaluated associations between sociodemographic characteristics and patterns of tobacco use.

RESULTS

Former (16.2%) was the most common tobacco use group, followed by single (10.8%), dual (4.5%), and poly (2.4%) use. Dual and poly use were more prevalent among males, Whites/Caucasians, older participants, and participants living in households with tobacco users. Kentucky residents (vs New York) had higher odds of dual use (OR=5.15; 95% CI: 1.72–15.44), and youth who used smartphones for ≥20hours/week (vs <20 hours/week) had greater odds of poly use (OR=3.02; 95% CI: 1.34–6.80).

CONCLUSIONS

Differences in single, dual, and poly tobacco use were evidenced by sociodemographic characteristics. Additional inquiry should further examine these disparities so that tobacco prevention interventions can be appropriately tailored.

Associations between Appalachian youth tobacco consumption and communication channel use

INTRODUCTION

Youth tobacco use rates in Appalachia exceed the US national average, and e-cigarette use has increased. Thus, further research is needed to understand how these youth receive and share product information.

METHODS

Middle and high school students in rural Appalachia were surveyed (N=1103). The primary outcome, tobacco use, was categorized as: never users, cigarette-only users, smokeless-only users, e-cigarette-only users, and polytobacco users. Associations between receiving or sharing conventional tobacco-related or e-cigarette-related information via specific communication channels and tobacco use were assessed.

RESULTS

Participants who received tobacco information from friends and family (FF) (OR=1.87; 95% CI: 1.35–2.57), public displays (PUB) (OR=1.49; 95% CI: 1.09–2.05), and digital media (DIG) (OR=1.95; 95% CI: 1.41–2.70) and e-cigarette information via the same communication channels, FF (OR=2.65; 95% CI: 1.93–3.65), PUB (OR=1.62; 95% CI: 1.17–2.26), and DIG (OR=2.24; 95% CI: 1.61–3.12), had greater odds of being polytobacco users, compared to never users. Participants who received e-cigarette-related information from FF (OR=2.42; 95% CI: 1.42–4.13) and PUB (OR=2.13; 95% CI: 1.25–3.65) had greater odds of being e-cigarette-only users compared to never users. Participants who shared e-cigarette-related information with FF had greater odds of being e-cigarette-only users (OR=3.16; 95% CI: 1.80–5.58) and polytobacco users (OR=4.48; 95% CI: 3.16–6.35) compared to never users.

CONCLUSIONS

Receiving and sharing tobacco-related and e-cigarette-related information via multiple communication channels is associated with e-cigarette and polytobacco use among Appalachian youth. Several channels may need to be utilized in health campaigns to influence youth.

Cigarette smoking, ENDS use and dual use among a national sample of lesbians, gays and bisexuals

INTRODUCTION

Historically, lesbian, gay and bisexual (LGB) individuals have higher rates of cigarette smoking, often attributed to targeted tobacco advertising, exposure to stressors, and psychological distress. Elevated use of electronic nicotine delivery systems (ENDS) among LGB individuals has been documented recently. However, the LGB groups are not homogeneous and differences may exist between the use of tobacco by men and women within the LGB groups. The purpose of this research was to examine cigarette smoking, ENDS use and dual use (cigarettes plus ENDS) among LGB subgroups.

METHODS

We classified 2087 participants completing a national online survey based on tobacco-use status (i.e. cigarette only, ENDS only, dual use) and sexual orientation. Multinomial logistic regression was employed to assess group differences.

RESULTS

After adjusting for demographics and socioeconomic status, bisexual women were 1.85 times (95% CI: 1.19–2.87) more likely to report current dual use, in contrast to cigarette only use, compared to heterosexual women. No significant differences were found between lesbian and heterosexual women, or between gay or bisexual men and their heterosexual counterparts.

CONCLUSIONS

This study describes significantly greater dual use by bisexual women and is one of the first reports of elevated dual use in this group compared to heterosexual women. These findings suggest that targeted health messages may be needed to raise awareness of risk in specific LGB groups and that future research with these populations is necessary to better understand differences in tobacco perceptions and use.

Tobacco use and harm perceptions among Appalachian youth

•

Over one-third had tried tobacco and over one-fifth had tried two or more products.

•

Most participants recognized harms associated with conventional tobacco use.

•

E-cigarettes were perceived as less harmful than conventional tobacco products.

•

Smokers and polytobacco users had lower odds of indicating tobacco health risks.

•

E-cigarette users were less likely to perceive e-cigarettes as harmful or addictive.

Appalachian youth tobacco use rates exceed the national average. Additional inquiry is needed to better understand youth product perceptions and use patterns. This study examined tobacco harm perceptions and their relationship with tobacco use among Appalachian youth. From 2014 to 2016, a survey of Appalachian middle and high school students (N = 1,136) was conducted. Tobacco harm perceptions were assessed by tobacco use status, categorized as never user, cigarette only user, smokeless only user, e-cigarette only user, or polytobacco user. Descriptive characteristics were compared by tobacco use status and harm perceptions. Adjusted multivariable logistic regression models assessed the relationship between tobacco use status and harm perceptions. Over one-third of participants were tobacco users (34.6%; 4.7% cigarette only users, 3.3% smokeless only users, 5.6% e-cigarette only users, and 21.0% polytobacco users). Approximately half agreed that e-cigarettes cause health problems (54.4%), and 64.7% agreed that e-cigarettes are addictive. Most participants (83.4–92.3%) agreed that smoking and smokeless tobacco cause health problems and are addictive. Tobacco users more often disagreed that tobacco products cause health problems than did never users. Compared to never users, e-cigarette only users were more likely to disagree that smoking (AOR: 2.99, 95% CI: 1.30–6.90) and e-cigarettes cause health problems (AOR: 2.79, 95% CI: 1.64–4.75) and that e-cigarettes cause addiction (AOR: 2.48, 95% CI: 1.48–4.16). Most youth were aware of health dangers associated with smoking, but perceptions were split on whether e-cigarettes were associated with health problems or addiction.

The findings indicate the need for additional youth tobacco use prevention efforts.

Correlates of youth vaping flavor preferences

•

ENDS were the tobacco products most likely to be tried first.

•

Fruit was the favorite flavor, followed by menthol/mint/wintergreen.

•

Preference for flavor varied by age, sex and racial/ethnic background.

•

Those who preferred fruit flavor were twice as likely to have tried ENDS first.

•

Those who preferred menthol/mint/wintergreen were less likely to have tried ENDS first.

Among youth who use electronic nicotine delivery systems (ENDS), e-cigarettes are often the first tobacco product tried. Flavor is a common reason for experimentation with e-cigarettes. This study assessed flavor preferences and the choice of ENDS as an initial product among youth by selected demographic characteristics. The analysis sample included 1549 participants who had ever tried ENDS, drawn from a national online survey of youth aged 13–18 in 2017. Fruit was the most common favorite flavor among ENDS users, followed by menthol/mint/wintergreen. Preference for flavor varied by age, sex and racial/ethnic background. ENDS were the tobacco products most likely to be tried first, particularly among participants under age 17. Those who preferred fruit flavor were twice as likely to have tried ENDS first, compared to those with other flavor preferences, while those who preferred menthol/mint/wintergreen flavor were half as likely to have tried ENDS first. Our findings support an association between flavor and ENDS use. Our research supports previous findings indicating that: 1) flavor is one of the primary reasons for experimentation with ENDS among youth; 2) fruit flavor is strongly associated with use of ENDS as the first tobacco product; and 3) preference of fruit flavor varies by age, sex and racial/ethnic background. These findings have relevance for developing targeted messages for specific youth audiences and implications for tobacco regulatory policies. In addition to January 2020 federal regulations, the authors recommend tighter restrictions, specifically that the marketing and sale of all e-cigarette flavors other than tobacco be eliminated.

Relationship between population characteristics, e-cigarette and tobacco-related perceptions, and likelihood of ever using e-cigarettes

INTRODUCTION

Electronic nicotine delivery systems (ENDS) are a relatively new type of nicotine-containing product that has risen greatly in use within the past decade, displacing conventional tobacco products as the dominant source of nicotine exposure by many groups. Among those impacted are large sections of US youth. Though health outcomes associated with ENDS use are still being assessed, several potential harms have been noted in the extant literature. The purpose of this study is to examine which US youth subpopulations are at greatest risk for ENDS ever use and how perceptions pertaining to nicotine-containing products relate to this risk.

METHODS

A nationwide online survey was administered to US youth ENDS users and non-users aged 13–18 years. A total weighted sample of 2501 participants was obtained. Statistical analyses included binomial logistic regression and a likelihood ratio test.

RESULTS

Of these youth, 1346 (53.8%) reported having ever used an ENDS product. Those most likely to have used ENDS were White males in their late teens. Those who reported ever using a conventional tobacco product were much more likely to have reported ever using ENDS (AOR= 19.96; 95% CI: 15.30–26.05). A number of perceptions related to nicotine-containing products, including product safety and health effects, were significantly associated with an increased likelihood of ENDS use.

CONCLUSIONS

Certain sections of the US youth population have elevated odds of being ENDS ever users. As increasing evidence supports the need to combat ENDS use by youth, effectively targeted education and prevention campaigns will be necessary.

Age differences in electronic nicotine delivery systems (ENDS) usage motivations and behaviors, perceived health benefit, and intention to quit

INTRODUCTION

Data from comprehensive studies are sparse regarding age differences in issues related to electronic nicotine delivery systems (ENDS) usage. This study examined age differences in usage motivations and behaviors, perceived health benefit, and quit intentions in a large and diverse sample recruited online.

METHODS

The sample included 1,432 current ENDS users, ages 18-64, drawn from a national online survey conducted in 2016. Descriptive and multivariable analyses were used.

RESULTS

The sample included participants in the following age groups: 18-24 (17.5%), 25-34 (38.6%), 35-44 (23.3%), and 45-64 (20.7%). With multiple adjustments, the 18-24 age group was more likely to vape for reasons such as flavors or friends' use, and to use multiple flavors and products with varying nicotine content. For example, the odds (95% CI) of vaping initiation due to flavor attraction vs. other reasons in the 18-24 age group were 1.40 (1.02-1.92), 2.73 (1.85-3.99), and 2.12 (1.41-3.18) compared to the 25-34, 35-44, and 45-64 age groups, respectively. In contrast, compared to older age groups, the 18-24 age group was less likely to use ENDS as an alternative to cigarettes or as a quitting device; they also used ENDS less frequently and perceived less health benefit of ENDS use. The 18-24 age group, especially those who had only used ENDS, had the lowest odds of likely quitting use of tobacco/nicotine products compared to other groups (lower by 44-73%).

CONCLUSION

There were significant age differences in ENDS usage motivations and behaviors, perceived health benefit, and quit intentions.

Perceived health risks of electronic nicotine delivery systems (ENDS) users: The role of cigarette smoking status

INTRODUCTION

Use of electronic nicotine delivery systems (ENDS) has increased markedly. We examined how current ENDS users differ in perceptions of tobacco and ENDS-related health risks as a function of cigarette smoking status.

METHODS

We classified 1329 current ENDS users completing a national online survey based on cigarette smoking status, and employed linear and logistic regression to assess group differences in perceptions of tobacco-related health risks.

RESULTS

The sample consisted of 38% Current Cigarette Smokers, 40% Former Cigarette Smokers, and 22% Non-Smokers. Our targeted recruitment strategy yielded a balance of key descriptive variables across participants. Significant differences were observed in race, employment and marital status across cigarette smoking status, but not in gender, education, income, or sexual orientation. Participants reported considerable perceived knowledge about health risks associated with tobacco use, but less regarding ENDS use. Current Smokers rated ENDS use as riskier than Non-Smokers, and considered cigarette use less risky for both users and bystanders. Current Smokers were more likely to perceive cardiovascular diseases, diabetes and cancer as the health risks associated with ENDS use. Former Smokers were more likely to perceive such risks with traditional tobacco use. Further, regardless of smoking status, perceived knowledge about the health risks of tobacco or ENDS use was positively associated with perceived likelihood of high risks of cardiovascular diseases and cancer.

CONCLUSIONS

Among current ENDS users, there were significant differences in perceived health risks based on cigarette smoking history. Improved health messaging can be achieved when cigarette smoking status is taken into account.

Responses to cigarette health warning labels, harm perceptions and knowledge in a national sample of pregnant and non-pregnant women of reproductive age

INTRODUCTION

Little is known about the effectiveness of cigarette health warning labels (HWLs) among U.S. pregnant and non-pregnant women of reproductive age. Our intent was to examine HWL responses by pregnancy status and their associations with knowledge and perceived harm.

METHODS

We conducted cross-sectional analyses of first (2013-2014) and second (2014-2015) Population Assessment of Tobacco and Health waves. The sample (N = 19,095) was representative of U.S. women of reproductive age (18-45 years). We examined three HWL responses (seeing HWLs, forgoing cigarettes because of HWLs, likely-to-quit because of HWLs), perceived harm from smoking, and knowledge of health effects to fetuses and others. Weighted logistic regression compared HWL responses by pregnancy status and their associations with perceived harm and knowledge, adjusting for demographics and tobacco use. Results were presented as marginal predicted probabilities.

RESULTS

Pregnant smokers were less likely than never-pregnant smokers to report likelihood of quitting (57% vs 67%, p = 0.020). Forgoing cigarettes and likely-to-quit due to HWLs-but not seeing HWLs-were positively associated with perceived harm and knowledge. Pregnant smokers were less likely to have knowledge of fetal harm (83%) than ever-pregnant (91%, p = 0.006) and never-pregnant (92%, p = 0.003) smokers. However, pregnant smokers who reported likelihood of quitting were much more likely to have knowledge of fetal harm than those who did not (93% vs. 67%, p = 0.028).

CONCLUSIONS

Implementation of HWLs that elicit stronger reactions-such as pictorial HWLs-and increase knowledge of fetal risks is one action to help reduce tobacco use in pregnant and non-pregnant U.S. women of reproductive age.

Differences in quality of life among college student electronic cigarette users

PURPOSE

The purpose of this study was to explore an association between e-cigarette use and Quality of Life (QOL) among college students.

METHODS

During February 2016, 1,132 students completed an online survey that included measures of tobacco use and the WHOQOL-BREF instrument. Differences were tested using Chi-square, Fisher's exact test, and ANOVA, and regression was used to assess possible relationships.

RESULTS

E-cigarettes were used by 6.97% of the participants, either solo or along with traditional cigarettes. Bivariate analyses suggest that male college students are more likely than females to use e-cigarettes, either solo or in combination with traditional cigarettes (χ2 =19.4, P < .01). Lesbian, gay, and bisexual students are more likely than heterosexual students to use traditional cigarettes, either solo or in combination with e-cigarettes (χ2 = 32.9, P < .01). Multivariate models suggest that for every 10-unit increase in overall QOL, psychological well-being, social relations or environmental health the adjusted odds of being a sole cigarette user were significantly lower (all, P < .01), respectively. For every 10-unit increase in psychological well-being the adjusted odds of being a dual user was significantly lower (OR = .83, P = .026).

CONCLUSIONS

Findings indicate that lower quality of life appears to be connected to tobacco use.

E-cigarette use and perceived health change: Better health through vaping?

INTRODUCTION

As e-cigarette use increases, questions about individual and public health effects remain unanswered (e.g. cessation tool, addiction path). Despite increasing use, few studies have focused on vape shop patrons. This study examined whether vape shop patrons believe their health is affected by the use of e-cigs; more specifically, the aim was to evaluate the association between e-cig use, change in tobacco use, and perception of health.

METHODS

A survey of e-cig users (N=78) was conducted in vape shops. Questions included e-cig and traditional tobacco use, health perceptions, and demographics. Descriptive techniques were used to characterize participants as either those who perceived e-cig use improved their health or those who perceived their health unaffected. Logistic regression assessed the association between change in tobacco use, e-cig use, and perception of health effects.

RESULTS

Most reported daily e-cig (91%) and current (11.5%) or former (78.2%) combustible cigarette use. Approximately, three-fourths (76.9%) perceived better health; the remainder (23.1%) perceived unaffected health. Change in cigarette use was significantly associated with perceptions that health is better with e-cig use. Participants who decreased cigarette use by 2-3 cartons/month and more than 3 cartons/month were significantly more likely to indicate that e-cig use has improved their health compared to those who decreased tobacco use by 1.5 cartons or fewer per month (OR=4.35, 95% CI: 1.13-16.9; OR=25.67, 95% CI: 2.97-221.7, respectively).

CONCLUSIONS

The majority of e-cig users perceived better health. Our findings suggest that health campaign designers should carefully assess the scientific uncertainty surrounding the use of these devices and consider means to clearly convey this information. Given the lack of scientific agreement on the health effects of e-cigs and the important role that perceptions play in behavior, health campaign designers, health education practitioners, policy makers, and health care providers should err on the side of caution when advising individuals about e-cig use.

Dual Users and Electronic Cigarette Only Users: Consumption and Characteristics

BACKGROUND

E-cigarette use has grown in popularity, especially as the devices have been touted as smoking cessation tools. In an exploratory study, we sought to compare dual users (i.e., users of both combustible tobacco and e-cigarettes) to e-cigarette only users.

METHODS

The Electronic Cigarette Opinion Survey (ECOS) was employed to assess users' (n=78) perceptions and consumption of e-cigarettes and combustible cigarettes. Quantity of e-juice and nicotine used and time of initial nicotine exposure were assessed. Multivariable logistic regression was used to evaluate the association between e-cigarette use behaviors and being an e-cigarette only user compared to a dual user.

RESULTS

Compared to dual users, e-cigarette only users consumed higher levels of nicotine in e-juice (p=0.0009) and more nicotine per month (p=0.03). For dual users, the time of first nicotine exposure after waking was significantly earlier than for e-cigarette only users (mean= 9.6 minutes (SD= 8.0) and mean= 26.6 minutes (SD= 22.0), respectively; p=0.0056). Results from the regression models suggest the amount of e-juice consumed and time of first nicotine exposure after waking are significantly associated with being an e-cigarette only user.

CONCLUSIONS

These findings shed light on the perceptions and use patterns of e-cigarette only users compared to dual users. As regulation of e-cigarettes is considered, understanding the impact of e-cigarettes and dual use is imperative. Despite frequent marketing claims that e-cigarettes are completely safe, health campaigns need to convey emerging and mixed findings on safety as well as current scientific uncertainty to the public.

The 'state' of tobacco: Perceptions of tobacco among Appalachian youth in Kentucky

INTRODUCTION

In Appalachia, youth tobacco-use rates remain higher than the U.S. national average. Past research has indicated that several factors are related to high rates of tobacco use among Appalachian youth (e.g. low socioeconomic status, rural lifestyles). Of the Appalachian states, Kentucky has one of the highest rates of youth tobacco use. The aim of this study was to explore views of tobacco among Kentucky youth living in Appalachian counties.

METHODS

In Fall 2014 - Spring 2015, focus group interviews were conducted with middle and high school students (N=109) in Appalachian counties in Kentucky. Each focus group session included open-ended questions and was conducted by trained facilitators. Focus group transcriptions and field notes were analyzed for themes.

RESULTS

Study participants described an entrenched culture of tobacco. Three themes exemplified this culture. First, adult behavior served to enable youth tobacco use (e.g. teachers ignoring dip use in class, adults smoking with youth). Second, tobacco is easily accessible to youth (e.g. restrictions on youth sales are often ignored, family members provide). Third, symbols of tobacco are prevalent (e.g. festivals celebrating tobacco heritage, tobacco barns, and tobacco marketing logos).

CONCLUSIONS

Youth participants described a deeply rooted tobacco culture, which they believed was unlikely to change. Additional studies and health education efforts are needed in these rural communities. Further, stricter enforcement of tobacco sales and marketing restrictions may be helpful in protecting this vulnerable population.

A novel text message-based motivational interviewing intervention for college students who smoke cigarettes

INTRODUCTION

Tobacco use disorder is critical among people aged 16 to 25 years. College campuses are prime locations for smoking cessation interventions for young adults. The vast majority of the smoking research with college students has been epidemiological in nature. This study examined a novel motivational interviewing intervention designed for college students, and explored predictors of smoking behavior change.

METHODS

A quasi-experimental one group pretest-posttest design with repeated measures was used to evaluate a novel text message-based brief motivational interviewing intervention. The data were collected from undergraduate students (N=33) who smoked cigarettes in Fall 2015.

RESULTS

Students’ level of autonomy and relatedness needs satisfaction, autonomous motivation, and smoking cessation self-efficacy increased (p < 0.05), and their rate of daily smoking declined (p <0 .05) over time. However, competence need satisfaction, readiness to quit smoking and severity of nicotine addiction remained unchanged. Smoking cessation self-efficacy was the strongest predictor of smoking behavior change in college students.

CONCLUSIONS

This study adds to the knowledge on smoking behavior among college students. Preliminary evidence indicates that text message-based motivational interviewing and smoking cessation self-efficacy may help guide successful smoking behavior interventions for college students.

Generally Recognized as Safe: Uncertainty Surrounding E-Cigarette Flavoring Safety

Despite scientific uncertainty regarding the relative safety of inhaling e-cigarette aerosol and flavorings, some consumers regard the U.S. Food and Drug Administration’s “generally recognized as safe” (GRAS) designation as evidence of flavoring safety. In this study, we assessed how college students’ perceptions of e-cigarette flavoring safety are related to understanding of the GRAS designation. During spring 2017, an online questionnaire was administered to college students. Chi-square p-values and multivariable logistic regression were employed to compare perceptions among participants considering e-cigarette flavorings as safe and those considering e-cigarette flavorings to be unsafe. The total sample size was 567 participants. Only 22% knew that GRAS designation meant that a product is safe to ingest, not inhale, inject, or use topically. Of participants who considered flavorings to be GRAS, the majority recognized that the designation meant a product is safe to ingest but also considered it safe to inhale. Although scientific uncertainty on the overall safety of flavorings in e-cigarettes remains, health messaging can educate the public about the GRAS designation and its irrelevance to e-cigarette safety.

Clean, cheap, convenient: promotion of Electronic cigarettes on YouTube

INTRODUCTION

Videos promoting electronic cigarettes (e-cigarettes) can be easily accessed on YouTube. Marketing claims present in YouTube videos may help shape the public's opinion of e-cigarettes. Thus, it is important to understand the most frequent marketing claims and video sources.

METHODS

The objectives of this study were to 1) identify marketing claims in YouTube videos that are commonly made on e-cigarette retail websites and 2) compare the frequency of marketing claims in user-generated and professional YouTube videos. Through content analysis, this study evaluated six marketing claims and descriptive information about YouTube videos (n = 50) related to "electronic cigarettes" and "vape".

RESULTS

Overall, the most frequent marketing claim promoted e-cigarette use as better than traditional tobacco use (52%). Approximately 65% of videos appeared to be user-generated and 35% were professionally-produced. Compared to user-generated videos, significantly more professional videos made claims that e-cigarettes are cleaner (p < 0.001) and cheaper (p = 0.04) than traditional cigarettes. Additionally, more professional videos had claims promoting e-cigarettes as better than traditional cigarettes because of their convenience-the user can smoke anywhere (p < 0.0001) and the products do not produce secondhand smoke (p < 0.001). The most frequent claim in user-generated videos was related to recreation (53%).

CONCLUSIONS

Videos on YouTube promote e-cigarettes as safer than other tobacco products. Videos appearing to be user-generated contained different marketing claims compared to professional videos. Further research is necessary to assess how the perceived source of the video impacts the ways these marketing claims shape public perception and influence use.

A picture is worth a thousand words: Electronic cigarette content on Instagram and Pinterest

INTRODUCTION

This study examined electronic cigarette (e-cig) content in visual materials posted on the social-media platforms Instagram and Pinterest. Both platforms allow users to upload pictures to the internet and share them globally. Users can search for pictures tagged with specific keywords and phrases.

METHODS

Using content analysis, this study identified themes in image postings of e-cigs on social media. During five weeks of data collection, keywords were used to identify pictures related to e-cigs. These pictures were then coded into one or more categories.

RESULTS

The three most popular categories for Instagram posts were marketing, customization and juices/flavors. The three most popular categories for Pinterest posts were customization, marketing and memes.

CONCLUSIONS

Because of the persuasive power of visuals, it is important to examine communication on Instagram and Pinterest as well as the specific visual messages communicated. Stores and manufacturers use these and similar platforms to communicate with users and potential users; thus it seems that marketers are capitalizing on opportunities for persuasive appeal. The results highlight the popularity of e-cig content on these two social media platforms and reveal an emphasis on marketing and customization.

Vape Shop Employees: Public Health Advocates?

INTRODUCTION

E-cigarettes have increased in popularity and given rise to a new type of sales outlet—the vape shop. Expanding on work examining vape shop employee e-cigarette and tobacco attitudes and behaviors¹, this study examined key messages that vape shop employees communicate to customers.

METHODS

Using informal interviews, observations, and a cross-sectional survey, we examined vape shop employees’ (n=16) perceptions and e-cigarette use. Data were collected in nine vape shops in Louisville, Kentucky. We used open coding to analyze the qualitative interviews, observation notes, and open-ended survey responses. Descriptive statistics were used to analyze survey data.

RESULTS

The findings revealed that nearly all employees were former smokers (93.8%), who now only use e-cigarettes. Over one-third of the employees (37.5%) began using e-cigarettes as a replacement for traditional cigarettes, and 93.8% reported better health (e.g., easier breathing, less coughing) since starting to use e-cigarettes. Although most employees believed e-cigarettes should be regulated, 56.3% thought regulations should be different from those governing traditional cigarettes. Analysis of qualitative data revealed that employees see themselves as health advocates who: 1) provide instructions on vaping and promote a vape community, 2) encourage cessation of traditional cigarettes, and 3) support some regulations.

CONCLUSIONS

The findings reveal that vape shop employees regard e-cigarettes as viable smoking cessation tools and relish their role in assisting others in taking what employees view as positive health actions. Future research addressing communication between vape shop employees and customers, especially related to smoking cessation and health, is needed.

Electronic Cigarettes and Communication: An Examination of College Students' Perceptions of Safety and Use

Electronic cigarettes (e-cigs) have increased in popularity over the last few years, especially with youth and young adults. However, little is known about the health effects of using these devices. Additionally, relatively few studies have explored college students' e-cig use and perceptions of safety. In this study, perceptions of e-cig safety were compared among three groups of college students-those who had never tried, had tried, and currently use e-cigs. Study findings suggest interesting differences between the three groups, with participants who had tried as well as those who currently use e-cigs having more positive views of the devices. For example, current users were more likely to view e-cigs as safe and healthy choices and less likely to view them as tobacco products. Further, compared to participants who had not tried e-cigs, individuals who had tried or currently use e-cigs were more likely to believe that vapor was safe to others (i.e., no second- or third-hand effects). Understanding the perceptions and use of e-cigs among college students is important in order to develop communication strategies for anti-tobacco campaigns that effectively relate safety concerns to these audiences.
