"I knew the effects the whole time." Examination of facilitators and barriers to quit vaping among adolescents.

Despite declines in adolescent nicotine vaping during the COVID-19 pandemic, vaping continues to be a public health issue for many adolescents. Most studies on teen reasons for vaping and on barriers and facilitators of vaping were conducted prior to the pandemic. Because teen culture changes so rapidly, and because the pandemic had wide-reaching effects on teens and mental health, it is critical to have a current understanding what helps adolescents to quit vaping (facilitators), as well as what prevents them from quitting (barriers) in order to design effective and engaging interventions. The objective of this qualitative study was to examine reasons for vaping, and barriers and facilitators to quitting vaping among high school age (14-18 years old) students. Students (n = 28; 60.7 % female; 50 % White, 10.7 % Black or African American, 25 % Asian or Asian American, 3.6 % other non-Hispanic; 7.2 % Hispanic; 21.4 % former vapers, 78.6 % current vapers) were recruited online from four regions in the US and participated in one of five online focus groups. We conducted a content analysis of the focus groups using a team-based coding approach. The most frequently cited reasons for vaping were mood, peer influence, and boredom. Results also showed that the stigma of seeking treatment acted as a barrier to quitting vaping, while self-reflection acted as a facilitator. In addition, two factors, peer influence and health effects, served as both barriers and facilitators, depending on the context. Program developers can use this information to design engaging vaping cessation programs intended for adolescents.

Intra-neighborhood associations between residential greenness and blood pressure.

INTRODUCTION: Previous investigations have reported that individuals living in greener neighborhoods have better cardiovascular health. It is unclear whether the effects reported at large geographic scales persist when examined at an intra-neighborhood level. The effects of greenness have not been thoroughly examined using high-resolution metrics of greenness exposure, and how they vary with spatial scales of assessment or participant characteristics. METHODS: We conducted a cross-sectional assessment of associations between blood pressure and multiple high-resolution measures of residential area greenness in spatially concentrated HEAL Study cohort of the Green Heart Project. We employed generalized linear models, accounting for individual-level covariates, to examine associations between different high-resolution measures of greenness and blood pressure among 667 participants in a 4 sq. mile contiguous neighborhood area in Louisville, KY. RESULTS: In adjusted models, we observed significant inverse associations between residential greenness, measured by leaf area index (LAI), and systolic blood pressure (SBP) within 150-250 m and 500 m of homes, but not for Normalized Difference Vegetation Index (NDVI) or grass cover. Weaker associations were also found with diastolic blood pressure (DBP). Significant positive associations were observed between LAI and SBP among participants who reported being female, White, without obesity, non-exercisers, non-smokers, younger age, of lower income, and who had high nearby roadway traffic. We found few significant associations between grass cover and SBP, but an inverse association in those with obesity, but positive associations for those without obesity. CONCLUSIONS: We found that leaf surface area of trees around participants home is strongly associated with lower blood pressure, with little association with grass cover. These effects varied with participant characteristics and spatial scales. More research is needed to test causative links between greenspace types and cardiovascular health and to develop population-, typology-, and place-based evidence to inform greening interventions.

Characteristics of Adolescents' and Young Adults' Exposure to and Engagement with Nicotine and Tobacco Product Content on Social Media.

To inform policy and messaging, this study examined characteristics of adolescents' and young adults' (AYAs') exposure to and engagement with nicotine and tobacco product (NTP) social media (SM) content. In this cross-sectional survey study, AYAs aged 13-26 (N=1,163) reported current NTP use, SM use frequency, and exposure to and engagement with SM content promoting and opposing NTP use (i.e. frequency, source[s], format[s], platform[s]). Participants who used NTPs (vs. did not use) were more likely to report having seen NTP content (p-values<.001). Prevalent sources were companies/brands (46.6%) and influencers (44.4%); prevalent formats were video (65.4%) and image (50.7%). Exposure to content promoting NTP use was prevalent on several popular platforms (e.g. TikTok, Instagram, Snapchat); exposure to content opposing NTP use was most prevalent on YouTube (75.8%). Among those reporting content engagement (i.e. liking, commenting on, or sharing NTP content; 34.6%), 57.2% engaged with influencer content. Participants reported engaging with content promoting and opposing NTP use on popular platforms (e.g. TikTok, Instagram, YouTube). Participants with (versus without) current NTP use were significantly more likely to use most SM platforms and to report NTP content exposure and engagement (p-values<.05). Results suggest that NTP education messaging and enforcement of platforms' content restrictions are needed.

Greenspaces And Cardiovascular Health.

Accumulating evidence suggests that living in areas of high surrounding greenness or even brief exposures to areas of high greenery is conducive to cardiovascular health, which may be related to the environmental, social, psychological, and physiological benefits of greenspaces. Recent data from multiple cross-sectional, longitudinal, and cohort studies suggest that living in areas of high surrounding greenness is associated with a lower risk of all-cause and cardiovascular mortality. High levels of neighborhood greenery have been linked also to a decrease in the burden of cardiovascular disease risk factors as reflected by lower rates of hypertension, dyslipidemia, and diabetes. Those who live in greener environments report better mental health and more frequent social interactions, which can benefit cardiovascular health as well. In this narrative review, we discuss evidence linking greenspaces to cardiovascular health as well as the potential mechanisms underlying the beneficial effects of greenspaces, including the impact of vegetation on air, noise and light pollution, ambient temperature, physical activity, mental health, and biodiversity. We review literature on the beneficial effects of acute and chronic exposure to nature on cardiovascular disease risk factors, inflammation and immune function, and we highlight the potential cardiovascular effects of biogenic volatile organic compounds that are emitted by trees and shrubs. We identify current knowledge gaps in this area and underscore the need for additional population studies to understand more clearly and precisely the link between greenness and health. Such understanding is urgently needed to fully redeem the promise of greenspaces in preventing adverse environmental exposures, mitigating the effects of climate change, and creating healthier living environments.

Trends in Current Electronic Cigarette Use Among Youths by Age, Sex, and Race and Ethnicity.

This cross-sectional study examines prevalence of electronic cigarette use among youths by age, sex, and race and ethnicity from 2013 to 2022.

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.

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.

Use of E-Cigarettes and Cigarettes During Late Pregnancy Among Adolescents.

Importance: Pregnant adolescents sometimes use cigarettes; however, little is known about e-cigarette use among pregnant adolescents, a population with increased health vulnerability. Objective: To examine yearly trends, sociodemographic and pregnancy-related determinants, and the association with small-for-gestational-age (SGA) birth of e-cigarette and/or cigarette use during late pregnancy among adolescents. Design, Setting, and Participants: This cohort study used existing data from the 2016-2021 Pregnancy Risk Assessment Monitoring System on 10 428 US adolescents aged 10 to 19 years who had a singleton birth with complete data on e-cigarette or cigarette use and SGA birth. Exposure: Adolescents reported e-cigarette and cigarette use during the last 3 months of pregnancy. Main Outcomes and Measures: SGA birth (birth weight below the 10th percentile for the same sex and gestational duration) was determined from birth certificates. Multivariable logistic regression was used to compare the odds of SGA birth across pregnant adolescents who exclusively used e-cigarettes, exclusively used cigarettes, used e-cigarettes and cigarettes, or did not use either. Results: Of the 10 428 pregnant adolescents, 72.7% were aged 18 or 19 years; 58.9% self-identified as White and 23.3% as Black; and 69.8% were non-Hispanic. The weighted prevalence of exclusive e-cigarette use during late pregnancy increased from 0.8% in 2016 to 4.1% in 2021, while the prevalence of exclusive cigarette use decreased from 9.2% in 2017 to 3.2% in 2021. The prevalence of dual use fluctuated, ranging from 0.6% to 1.6%. White pregnant adolescents were more likely than those who self-identified as another race and ethnicity to use e-cigarettes (2.7% vs 1.0% for American Indian or Alaska Native adolescents, 0.8% for Asian or other race adolescents, 0.6% for Black adolescents, and 0.7% for multiracial adolescents). Compared with those who did not use either product, adolescents who exclusively used e-cigarettes (16.8% vs 12.9%; confounder-adjusted odds ratio [AOR], 1.68 [95% CI, 0.89-3.18]) or who used cigarettes and e-cigarettes (17.6% vs 12.9%; AOR, 1.68 [95% CI, 0.79-3.53]) had no statistically significant difference in risk of SGA birth. However, adolescents who exclusively used cigarettes had a more than 2-fold higher risk of SGA birth (24.6% vs 12.9%; AOR, 2.51 [95% CI, 1.79-3.52]). Conclusions and Relevance: This cohort study suggests that pregnant adolescents increasingly used e-cigarettes, with the highest use among White adolescents. Results from this analysis found that, unlike cigarette use, e-cigarette use during late pregnancy was not statistically significantly associated with an increased risk of SGA birth among adolescents. Due to the uncertainty of this nonsignificant association, future research could benefit from a larger sample size.

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.

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.

Greenness and equity: Complex connections between intra-neighborhood contexts and residential tree planting implementation.

Associations between neighborhood greenness and socioeconomic status (SES) are established, yet intra-neighborhood context and SES-related barriers to tree planting remain unclear. Large-scale tree planting implementation efforts are increasingly common and can improve human health, strengthen climate adaptation, and ameliorate environmental inequities. Yet, these efforts may be ineffective without in-depth understanding of local SES inequities and barriers to residential planting. We recruited 636 residents within and surrounding the Oakdale Neighborhood of Louisville, Kentucky, USA, and evaluated associations of individual and neighborhood-level sociodemographic indicators with greenness levels at multiple scales. We offered no-cost residential tree planting and maintenance to residents within a subsection of the neighborhood and examined associations of these sociodemographic indicators plus baseline greenness levels with tree planting adoption among 215 eligible participants. We observed positive associations of income with Normalized Difference Vegetation Index (NDVI) and leaf area index (LAI) within all radii around homes, and within yards of residents, that varied in strength. There were stronger associations of income with NDVI in front yards but LAI in back yards. Among Participants of Color, associations between income and NDVI were stronger than with Whites and exhibited no association with LAI. Tree planting uptake was not associated with income, education, race, nor employment status, but was positively associated with lot size, home value, lower population density, and area greenness. Our findings reveal significant complexity of intra-neighborhood associations between SES and greenness that could help shape future research and equitable greening implementation. Results show that previously documented links between SES and greenspace at large scales extend to residents' yards, highlighting opportunities to redress greenness inequities on private property. Our analysis found that uptake of no-cost residential planting and maintenance was nearly equal across SES groups but did not redress greenness inequity. To inform equitable greening, further research is needed to evaluate culture, norms, perceptions, and values affecting tree planting acceptance among low-SES residents.

Associations between biomarkers of nicotine/tobacco exposure and respiratory symptoms among adults who exclusively smoke cigarettes in the U.S.: Findings from the PATH Study Waves 1-4 (2013-2017).

Significance: Determining if tobacco-related biomarkers of exposure (BOE) are associated with respiratory symptoms is an important public health tool that can be used to evaluate the potential harm of different tobacco products. Methods: Adult data from people who exclusively smoked cigarettes (N = 2,438) in Waves 1-4 (2013-2017) of the Population Assessment of Tobacco and Health Study were stacked to examine associations between baseline and follow-up within wave pairs (W1-W2, W2-W3, W3-W4). Weighted generalized estimating equation models were used to evaluate associations between biomarkers of nicotine, tobacco-specific nitrosamines, acrolein, acrylonitrile, cadmium, and lead at baseline/follow-up and respiratory symptom(s) (wheezing/whistling in the chest, wheezing during exercise, and/or dry cough in the past 12 months) at follow-up. Results: Higher acrolein metabolite (CEMA) levels at follow-up were associated with increased odds of respiratory symptoms at follow-up for people who exclusively smoked cigarettes (aOR = 1.34; 95% CI = 1.06, 1.70), including when limited to those without a diagnosed respiratory disease (aOR = 1.46; 95% CI = 1.12, 1.90) and those who smoked daily (aOR = 1.40; 95% CI = 1.06, 1.84). Higher cadmium levels at baseline (while controlling for follow-up levels) were associated with reduced odds of respiratory symptoms at follow-up (aOR = 0.80; 95% CI = 0.65, 0.98) among people who exclusively smoked cigarettes without a respiratory disease. There were no significant associations between baseline/follow-up BOE and follow-up respiratory symptoms for people who smoked cigarettes non-daily. Conclusions: This research supports measuring biomarkers of acrolein, such as CEMA, as a potential intermediate measurement for increased respiratory symptom development. Measuring these biomarkers could help alleviate the clinical burden of respiratory disease.

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.

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; ß = 0.27, t = 6.67, p < .001) as well as its three subdomains (physical concerns: 4% variance; ß = 0.21, t = 4.97, p < .001; cognitive concerns: 6% variance; ß = 0.25, t = 6.17, p < .001; social concerns: 6% variance; ß = 0.26, t = 6.22, p < .001). Additionally, more time spent walking was associated with greater anxiety sensitivity physical concerns (1% variance; ß = 0.11, t = 2.52, p = .012) and greater vigorous intensity physical activity was associated with lower anxiety sensitivity social concerns (1% variance; ß = -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.
