Past 30-day Cigarette Smoking Research Articles

Cigarette and ENDS dual use longitudinal transitions among adults in the Population Assessment of Tobacco and Health (PATH) Study, Waves 4–5 (2016–2019)

IntroductionThe study assessed longitudinal transitions among adult (18 and older) past 30-day daily and non-daily dual users of cigarettes and electronic nicotine delivery systems (ENDS). MethodsUsing data from Wave 4 (W4; 2016/17) and Wave 5 (W5; 2018/19) of the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative, longitudinal cohort study of US adults, multivariable regressions were conducted among W4 dual users of cigarettes and ENDS to examine past 30-day cigarette smoking at W5. The study also analyzed changes in frequency of past 30-day smoking and cigarettes smoked per day between W4 and W5, stratified by W4/W5 daily/non-daily ENDS use among W4 daily and non-daily cigarette smokers. ResultsAmong W4 dual users, those smoking daily and using ENDS non-daily had higher odds of daily cigarette smoking at W5 than daily users of both products (AOR: 2.32, 95 % CI: 1.38–3.90). W4 daily smokers who used ENDS daily at Wave 5 smoked cigarettes on fewer days at Wave 5 than W4 daily smokers who were either daily ENDS users at Wave 4 (B = −4.59; SE = 1.43, p < 0.01) or non-daily ENDS users at Wave 4 (B = −4.55; SE = 1.24, p < 0.001). Among W4 non-daily cigarette smokers, W4 non-daily ENDS users who used daily at W5 smoked cigarettes on fewer days (B = −4.04, SE = 1.82) at W5 than those who were non-daily ENDS users at W4 and W5. ConclusionsFindings highlight the importance of frequency of ENDS use in reducing cigarette smoking and could inform smoking cessation interventions among daily cigarette smokers.

Characterization of trajectories of physical activity and cigarette smoking from early adolescence to adulthood

BackgroundCigarette smoking and physical inactivity are two critical risk factors for noncommunicable diseases and all-cause mortality. However, few studies have compared the long-term trajectories of both behaviors, as well as multilevel factors associated with trajectory patterns. Using the National Longitudinal Study of Adolescent to Adult Health (Add Health) Wave I through V survey data, this study characterized distinct subgroups of the population sharing similar behavioral patterns from adolescence to adulthood, as well as predictors of subgroup membership for physical activity (PA) and cigarette smoking behavior respectively.MethodsUsing the Add Health Wave I through V survey data, we identified the optimal number of latent classes and class-specific trajectories of PA and cigarette smoking from early adolescence to adulthood, fitting latent growth mixture models with standardized PA score and past 30-day cigarette smoking intensity as outcome measures and age as a continuous time variable. Associations of baseline sociodemographic factors, neighborhood characteristics, and sociopsychological factors with trajectory class membership were assessed using multinomial logistic regression.ResultsWe identified three distinct subgroups of non-linear PA trajectories in the study population: moderately active group (N = 1067, 5%), persistently inactive group (N = 14,257, 69%) and worsening activity group (N = 5410, 26%). Foror cigarette smoking, we identified three distinct non-linear trajectory subgroups: persistent non-smoker (N = 14,939, 72%), gradual quitter (N = 2357, 11%), and progressing smoker (N = 3393, 16%). Sex, race/ethnicity, neighborhood environment and perceived peer support during adolescence were significant predictors of both physical activity and cigarette smoking trajectory subgroup membership from early adolescence to adulthood.ConclusionsThere are three distinct subgroups of individuals sharing similar PA and cigarette smoking behavioral profile respectively from adolescence to adulthood in the Add Health study population. Behavioral interventions that focus on neighborhood environment (e.g. establish community-based activity center) and relationship to peers during adolescence (e.g. peer counseling) could be key to long-term PA promotion and cigarette smoking cessation.

Racial and Ethnic Differences in Initiation of Menthol Tobacco Smoking and Subsequent Tobacco Use in the Population Assessment of Tobacco and Health Study, Waves 1-4 (2013-2018).

Certain subpopulations in the United States are highly vulnerable to tobacco initiation and addiction, and elimination of disparities among those groups is crucial to reducing the burden of tobacco use. This study evaluated the racial and ethnic differences in smoking initiation of menthol flavored cigarettes and cigars among never-users, and in subsequent tobacco use among new users of menthol-flavored products, using longitudinal data from waves 1-4 of the Population Assessment of Tobacco and Health Study. The outcomes of interest were new use of menthol-flavored products, and subsequent past 30-day and past 12-month cigarette and cigar smoking, irrespective of flavors, after initiation. The percentages of new users of menthol-flavored cigarettes and cigars at waves 2-4 were disproportionately higher in non-Hispanic black and Hispanic than in non-Hispanic white people. Adjusting for age and sex, black people who first used any menthol cigars had higher risk of past 30-day use of the same cigar category at the subsequent wave (adjusted risk ratio, aRR 1.48; 95% confidence interval [CI] 1.11 to 1.96) and past 12 months (aRR 1.74; 95% CI 1.55 to 2.63) compared to non-Hispanic white smokers. Black people who first used menthol-flavored cigarettes had marginally higher risk of subsequent past 30-day cigarette use (aRR 1.44; 95% CI 0.99 to 2.10) compared with their non-Hispanic white counterparts. This study shows that racial and ethnic differences exist in both initiation of menthol-flavored tobacco products and product-specific subsequent use after first using menthol-flavored products; black and Hispanic people have higher rates of initiation; black people also have higher rates of subsequent use. Use of menthol flavors in tobacco products is confirmed to be a contributor to large disparities in tobacco use; black and Hispanic people are more likely to maintain smoking through use of mentholated products than non-Hispanic white people. The findings suggest educational and regulatory actions on menthol-flavored tobacco products including restricting the selective marketing to vulnerable communities and banning characterizing flavors in cigarettes and cigars may reduce tobacco-related disparities and inform the Food And Drug Administration's evidence-based rulemaking process.

Adolescent use and co-use of tobacco and cannabis in California: The roles of local policy and density of tobacco, vape, and cannabis retailers around schools

Adolescent tobacco use (particularly vaping) andco-use of cannabis and tobacco have increased, leading some jurisdictions to implement policies intended to reduce youth access to these products; however, their impacts remainunclear. We examine associations between local policy, density of tobacco, vape, and cannabis retailers around schools, and adolescent use and co-use of tobacco/vape and cannabis.We combined 2018 statewide California(US) data on: (a) jurisdiction-level policies related to tobacco and cannabis retail environments, (b) jurisdiction-level sociodemographic composition, (c) retailer locations (tobacco, vape, and cannabis shops), and (d) survey data on 534,176 middle and high school students (California Healthy Kids Survey). Structural equation models examined how local policies and retailer density near schools are associated with frequency of past 30-day cigarette smoking or vaping, cannabis use, and co-use of tobacco/vape and cannabis, controlling for jurisdiction-, school-, and individual-level confounders.Stricter retail environment policies were associated with lower odds of past-month use of tobacco/vape, cannabis, and co-use of tobacco/vape and cannabis. Stronger tobacco/vape policies were associated with higher tobacco/vape retailer density near schools, while stronger cannabis policies and overall policy strength (tobacco/vape and cannabis combined) were associated with lower cannabis and combined retailer densities (summed tobacco/vape and cannabis), respectively. Tobacco/vape shop density near schools was positively associated with tobacco/vape use odds, as was summed retailer density near schools and co-use of tobacco, cannabis.Considering jurisdiction-level tobacco and cannabis control policies are associated with adolescent use of these substances, policymakers may proactively leverage such policies to curb youth tobacco and cannabis use.

Impact of the e-cigarette era on cigarette smoking among youth in the United States: A population-level study

To examine and compare trends in past 30-day cigarette smoking among adolescents in the US from 2002 to 2019, before and after the onset of the "e-cigarette era" in 2014. Using National Youth Tobacco Survey (NYTS) data from 2002 to 2019, we modeled the prevalence of past 30-day cigarette smoking over time. A total of n=274,551 (weighted N=340,403,754) middle and high school students were included in this study. Interrupted time series analyses were used to examine changes in cigarette smoking over time and compare trends in cigarette smoking pre- and post-2014. Models were applied to the full sample and stratified by middle (6th-8th grade) and high school (9th-12th grade). The observed number of current adolescent cigarette smokers post-2014 was compared to the predicted number, given trends in cigarette smoking prevalence observed pre-2014. Among all students, past 30-day cigarette smoking declined by approximately 0.75% per year from 2002 to 2013 (p<0.001). Following a significant drop in prevalence from 2013 to 2014 (1.64%; p<0.001), the decline in past 30-day cigarette smoking slowed significantly to approximately 0.37% per year (p<0.001), from 2015 to 2019. We estimate that the onset of the "e-cigarette era" in 2014 corresponded to over 1.66 million (95% CI: 1.57m - 1.75m) more past 30-day cigarette smokers from 2015 to 2019, cumulatively. The rate of decline in past 30-day cigarette smoking prevalence among adolescents observed since 2002 slowed with the onset of the "e-cigarette era" in 2014, providing evidence at a population-level for the "gateway effect."

Differences between adult sexual minority females and heterosexual females on menthol smoking and other smoking behaviors: Findings from Wave 4 (2016–2018) of the population assessment of tobacco and health study

BackgroundSexual minority females have higher rates of cigarette smoking than heterosexual females. Additionally, menthol cigarette use disproportionately impacts minority smokers, including sexual minority individuals. This study examined differences between sexual minority and heterosexual females on several smoking variables, including initiation with a menthol cigarette, and past 30-day cigarette and menthol cigarette use. MethodsParticipants were female ever smokers (N = 11,576; n = 1,474, 12.7% sexual minority) who completed Wave 4 of the Population Assessment of Tobacco and Health Survey. Participants reported on the age they began smoking regularly (≤18 years old, 18–24, >25), whether they initiated with a menthol cigarette, past 30-day cigarette smoking and menthol cigarette use, cigarettes smoked per day (≤10, 11–20, >20), cigarette dependence (smoke ≤ 5 min of waking or > 5 min of waking), and whether they were a current (someday/every day) or former (no past year/current use) established smoker (≥100 lifetime cigarettes), or an experimental smoker (<100 lifetime cigarettes). Chi-square and multivariable logistic regression analyses examined differences between sexual minority females and heterosexual females on smoking variables. ResultsSexual minority female smokers began smoking regularly at an earlier age and smoked fewer cigarettes per day than heterosexual females. Sexual minority females were more likely to initiate smoking with a menthol cigarette (aOR = 1.27), report past 30-day smoking (aOR = 1.36) and menthol cigarette use (aOR = 1.24) compared to heterosexual females. There were no differences on cigarette dependence. ConclusionsGiven the high rates of initiation and current menthol smoking, policies to regulate menthol may decrease smoking disparities for sexual minority females.

Integrating Financial Coaching and Referrals into a Smoking Cessation Program for Low-income Smokers: a Randomized Waitlist Control Trial.

Financial distress is a barrier to cessation among low-income smokers. To evaluate an intervention that integrated financial coaching and benefits referrals into a smoking cessation program for low-income smokers. Randomized waitlist control trial conducted from 2017 to 2019. Adult New York City residents were eligible if they reported past 30-day cigarette smoking, had income below 200% of the federal poverty level, spoke English or Spanish, and managed their own funds. Pregnant or breastfeeding people were excluded. Participants were recruited from two medical centers and from the community. The intervention (n = 208) offered smoking cessation coaching, nicotine replacement therapy, money management coaching, and referral to financial benefits and empowerment services. The waitlist control (n=202) was usual care during a 6-month waiting period. Treatment engagement, self-reported 7-day abstinence, and financial stress at 6 months. At 6 months, intervention participants reported higher abstinence (17% vs. 9%, P=0.03), lower stress about finances (β, -0.8 [SE, 0.4], P=0.02), and reduced frequency of being unable to afford activities (β, -0.8 [SE, 0.4], P=0.04). Outcomes were stronger among participants recruited from the medical centers (versus from the community). Among medical center participants, the intervention was associated with higher abstinence (20% vs. 8%, P=0.01), higher satisfaction with present financial situation (β, 1.0 [SE, 0.4], P=0.01), reduced frequency of being unable to afford activities (β, -1.0 [SE, 0.5], P=0.04), reduced frequency in getting by paycheck-to-paycheck (β, -1.0 [SE, 0.4], P=0.03), and lower stress about finances in general (β, -1.0 [SE, 0.4], P = 0.02). There were no group differences in outcomes among people recruited from the community (P>0.05). Among low-income smokers recruited from medical centers, the intervention produced higher abstinence rates and reductions in some markers of financial distress than usual care. The intervention was not efficacious with people recruited from the community. ClinicalTrials.gov Identifier: NCT03187730.

Recent, national trends in US adolescent use of menthol and non-menthol cigarettes

ObjectiveIn light of the current U.S. Food and Drug Administration (FDA) proposal to ban menthol cigarettes, this study updates trends in menthol cigarette use among adolescents age 13–18 years up...

Cigarette Pack Price and Its Within-Person Association With Smoking Initiation, Smoking Progression, and Disparities among Young Adults.

There is a dearth of research on within-person relationships between tobacco price and cigarette smoking initiation and progression in young adulthood. This project examines the within-person association between cigarette pack price and smoking initiation and progression between age 18 and 21/22, focusing on differences across subgroups. Data came from the longitudinal Monitoring the Future (MTF) project. MTF examines drug use behaviors with nationally representative samples of 12th graders annually. Subsamples of 12th graders are annually selected and followed longitudinally. Among 12th graders from baseline years 2000-2014, we examined past 30-day cigarette smoking initiation among baseline never smokers (N = 15 280) and progression to daily smoking among youth who were not daily smokers at baseline (N = 26 998). We used hierarchical logistic regression and interaction terms to assess differences across sex, race/ethnicity, and parental education. The within-person relationship between pack price and smoking indicated that a one-dollar increase in pack price corresponded with a 72% decrease in the odds of initiation (AOR = 0.28, 95% CI = 0.18, 0.44) and 70% decrease in the odds of progression to daily smoking (AOR = 0.30, 95% CI = 0.21, 0.44). There was a linear age trend for both smoking initiation and progression. There were no statistically significant interactions between price and demographics, making it difficult to disentangle differences across subgroups. Exposure to increased cigarette prices during young adulthood was associated with lower odds of cigarette smoking initiation and progression. Additional policies and programs beyond cigarettes prices could help reduce tobacco-related disparities in smoking initiation and progression among young adults. There is a strong, within-person relationship between cigarette prices and smoking initiation and progression during the transition to young adulthood: higher prices are associated with decreased odds of both initiation and progression. Cigarette taxation can help to prevent smoking initiation and progression among youth, but it is less clear how taxes are associated with disparities in smoking experienced by certain subgroups. We could not draw definitive conclusions about the impact of cigarette prices on tobacco-related disparities. Tobacco taxes should be increased on a regular basis to ensure young adults experience within-person increases in prices, and complementary programs geared toward reducing tobacco-related disparities among young adults should be promoted.

Further Consideration of the Impact of Tobacco Control Policies on Young Adult Smoking in Light of the Liberalization of Cannabis Policies

Changing patterns of cannabis consumption related to the liberalization of cannabis policies may have a countervailing effect on tobacco use. We analyzed whether cannabis policies have tempered the effects of tobacco control policies as well as the extent to which they were associated with young adult cigarette smoking. Combining data on tobacco and cannabis policies at the state, county, and city levels with the nationally-representative geocoded National Longitudinal Survey of Youth 1997 and Census data, we use multilevel regression and fixed effect analyses to examine the impact of cannabis policies on any past 30-day cigarette smoking, frequency of smoking, and past 30-day near-daily smoking among young adults while accounting for community and individual covariates. Tobacco control policies, including significant effects of comprehensive smoking bans, total vending machine restrictions, single cigarette sale restrictions, and advertising restrictions, remain robust in reducing young adult smoking, net of cannabis policy liberalization, including the legal status of possession, penalties for sale, and medical cannabis. Cannabis policies do not directly affect young adult smoking patterns in an adverse way. This paper provides evidence that the liberalization of cannabis laws has not adversely affected the efficacy of tobacco control efforts. While the effects of tobacco control policies on smoking are well-established, little research has considered how the liberalization of cannabis policies may affect these relationships, which is important given the co-use of these substances. This paper provides evidence that the liberalization of cannabis laws has not adversely affected tobacco control efforts.

Minority stress, depression, and cigarette smoking among Chinese gay versus bisexual men: a two-group structural equation model analyses

BackgroundLiterature in the West suggested that bisexual men have a higher smoking rate compared to gay men. Data on patterns of smoking among gay and bisexual men are limited in Eastern Asian countries like China. This study examined the cigarette smoking prevalence for gay versus bisexual men in China and their unique minority stress - smoking pathways.MethodsBetween September 2017 and November 2018, we surveyed a convenience sample of 538 gay men and 138 bisexual men recruited from local sexual minority organizations in four metropolitan cities in China (i.e., Beijing, Wuhan, Nanchang, and Changsha). Measures included sexual orientation, sociodemographics, theory-based minority stressors, depressive symptoms, and past 30-day cigarette smoking. Two-group (gay men vs. bisexual men) structural equation modeling (SEM) was used to test possible distinct mechanisms between theory-based stressors, depressive symptoms, and cigarette smoking among gay men and bisexual men, respectively.ResultsThe mean age of participants was 26.51 (SD = 8.41) years old and 76.3% of them had at least a college degree. Bisexual men reported a higher rate of cigarette smoking compared to gay men (39.9% vs. 27.3%). Two-group SEM indicated that the pathways for cigarette smoking were not different between gay and bisexual men. Higher rejection anticipation was associated with greater depressive symptoms (standardized β = 0.32, p < .001), and depressive symptoms were not associated with cigarette smoking.ConclusionsMinority stress, specifically rejection anticipation, may be critical considerations in addressing depressive symptoms, but not smoking, among both gay and bisexual men in China.

Self-reported history of intensity of smoking is associated with risk factors for suicide among high school students.

ObjectiveTo examine the relationship between current cigarette smoking patterns and three established risk factors for suicide using nationally representative data of high school students in the United States.MethodsWe analyzed cross-sectional data from the national Youth Risk Behavior Surveillance Survey (YRBSS)–United States, 2017. Multivariable, logistic regressions examined the association between 3 cigarette smoking behaviors [i.e., past 30-day cigarette (n = 13,731), frequent (n = 1,093) and heavy (n = 880) smoking] and 3 risk factors for suicidal outcomes [feeling sad or hopeless, suicidal ideation, suicide plan] assessed over the previous year.ResultsAmong high school cigarette smokers, smoking 11 or more cigarettes per day (i.e., heavy smoking) was associated with 3.43 (95% CI: 1.69, 6.94) greater odds of reporting feeling sad or hopeless, 2.97 (95% CI: 1.60, 5.51) greater odds of reporting suicidal ideations, and 2.11 (95% CI: 1.34, 3.32) greater odds of reporting having ever planned a suicide attempt, controlling for covariates.ConclusionsOur study shows that it is not simply cigarette smoking, but heavy cigarette smoking that is a risk factor for suicidal outcomes among adolescents.Public health implicationsA comprehensive plan is needed to accommodate heavy adolescent smokers who are at increased suicidal risk.

Trends and Patterns of Tobacco and Nicotine Product Use Among Youth in Canada, England, and the United States From 2017 to 2019

PurposeThe tobacco and nicotine market is diversifying. Implications for public health will depend on trends in use, including overall use, and who is using these products. This study examined differences over time (2017–2019), across countries (Canada, England, the United States (US)), and by smoking and vaping, in use of other tobacco/nicotine products and overall use. MethodsThe study includes online repeat cross-sectional surveys of youth aged 16–19 years in Canada (N = 11,714), England (N = 11,170), US (N = 11,838) in 2017, 2018, and 2019. Past 30-day use of tobacco/nicotine products (any, cigarette, e-cigarette, other combusted [cigars/cigarillos/waterpipe], other non-combusted [smokeless tobacco/nicotine replacement therapies) were examined by country, year, and, for other combusted and non-combusted products, past 30-day cigarette smoking and vaping. Use of emerging products (IQOS, nicotine pouches) was explored in 2018–2019. ResultsFrom 2017 to 2019, use of any product increased in Canada (17.1%–23.2%, AOR = 1.07 [95% CI = 1.04–1.09]) and the US (18.0%–24.0%, AOR = 1.06 [1.04–1.09]) but not England (20.8%–21.7%, AOR = 1.01 [.99–1.03]). Use of other combusted products (cigars/cigarillos/waterpipe) showed little change (Canada: 8.1%–7.8%; England: 6.3%–7.3%; US: 8.6%–8.5%; p ≥ .151). Use of other non-combusted products (smokeless/nicotine replacement therapies) increased in all countries (Canada: 1.5%–3.2%, AOR = 1.02 [1.01–1.02]; England: 1.4%–2.6%, AOR = 1.02 [1.01–1.03]; US: 3.3%–4.9%, AOR = 1.02 [1.01–1.02]). Vaping increased in all countries (Canada: 8.4%–17.8%; England: 8.7%–12.6%; United States: 11.1%–18.5%; all p < .001). Smokers and vapers reported greater use of other combusted and non-combusted products than those who neither smoked/vaped (p < .001). Emerging product use was rare (≤1.5%). ConclusionsYouth past 30-day tobacco and nicotine product use increased from 2017 to 2019 in Canada and the United States, largely due to increases in vaping and other non-combusted products. “Other” tobacco/nicotine products were used predominantly by youth who smoked cigarettes and/or vaped.

Those who believe they can, do: The relationship between smoking avoidance beliefs, perceived risks of smoking, and behavior in a sexual and gender minority young adult sample

An individual’s beliefs in their perceived risk and ability to resist smoking have been found to be associated with smoking behavior. The current study explores the effects of confidence in one’s ability to avoid smoking, measured by avoidance beliefs, on the relationship between perceived risks of smoking and behavior. This analysis was done using 2016 baseline data collected among 4057 participants aged 18–24 for the evaluation of a large-scale public education campaign in the U.S. aimed at reducing tobacco use among sexual and gender minority young adults. The analytic sample included roughly 3493 participants per analysis. Analyses used the following measures: (1) perceived risks of smoking (e.g., smoking cigarettes will shorten my life); (2) confidence to avoid smoking in various situations (i.e., avoidance beliefs), and (3) past 30-day cigarette smoking. Binary logistic regression models with interaction analyses assessed the relationship between perceived risks of smoking and past 30-day smoking behavior using the interaction term of avoidance beliefs. An interaction between perceived risks of smoking and avoidance behaviors interaction emerged, such that the negative relationship between perceived risks of smoking and smoking behavior was stronger for those who believed that they could avoid smoking in various situations. This suggests that the relationship between perceived risk and smoking behavior can be bolstered if one’s beliefs about their ability to avoid smoking are strong. Campaigns that build smoking avoidance confidence may enhance the effects of tobacco outcome expectations-related messaging on smoking.

Does having one or more smoking friends mediate the transition from e-cigarette use to cigarette smoking: a longitudinal study of Canadian youth.

Studies have shown consistent associations between youth e-cigarette use and subsequent smoking uptake. However, it remains unclear why, as limited evidence exists regarding the mechanisms underlying these associations. Our study investigated whether having one or more smoking friends mediated the association between e-cigarette use and cigarette smoking onset among a longitudinal sample of Canadian youth who were never smokers at baseline. A longitudinal sample of youth that participated in three waves of the COMPASS study (2015-2016 to 2017-2018) was identified (N = 5,535). The product of coefficients method was used to assess whether having one or more smoking friends mediated the association between: (1) past 30-day e-cigarette use and cigarette smoking onset and (2) past 30-day e-cigarette use and subsequent dual use of e-cigarettes and cigarettes. Having one or more smoking friends did not mediate the association between (1) past 30-day e-cigarette use and cigarette smoking onset (β = 0.38, 95% CI -0.12, 0.89) or (2) past 30-day e-cigarette use and subsequent dual use (β = 0.46, 95% CI -0.16, 1.07). Post hoc tests indicated that smoking friends significantly predicted past 30-day e-cigarette use and cigarette smoking at wave 3 (aOR 1.68 and 2.29, respectively). Having smoking friends did not explain the association between e-cigarette use and smoking uptake despite being a common risk factor for both e-cigarette use and cigarette smoking. Prevention efforts should consider how best to incorporate effective programming to address these social influences.

Tobacco Taxation and Its Prospective Impact on Disparities in Smoking Initiation and Progression Among Young Adults

PurposeLimited research exists on tobacco taxes and cigarette smoking initiation and progression, particularly across different sociodemographic groups in young adulthood. This project examines how cigarette pack price in late adolescence prospectively relates to smoking initiation and progression by 21 years of age, focusing on differences across demographics. MethodsData are from the longitudinal Monitoring the Future project (2001–2017). Monitoring the Future examines drug use behaviors with nationally representative samples of 12th graders annually. Subsamples of 12th graders are followed up longitudinally. We examined past 30-day cigarette smoking among baseline never smokers (N = 9,232) and daily smoking among youths who were not daily cigarette smokers at baseline (N = 15,141). Using logistic regression, we examined state-level cigarette pack price at a modal age of 18 years and smoking at follow-up ages 19–20 years; we used interaction terms to assess differences across sociodemographic groups (by gender, race/ethnicity, and parental education). ResultsFor each dollar increase in price at baseline, the odds of initiation by age 19–20 years were reduced by 12% (adjusted odds ratio = .88; 95% confidence interval = .78, .99) and the odds of progression to daily smoking were reduced by 16% (adjusted odds ratio = .84; 95% confidence interval = .76, .92). After adjusting for multiple testing, for both outcomes there were no statistically significant interactions between price and demographics. ConclusionsCigarette prices in late adolescence were associated with a prospective reduction in cigarette smoking initiation and progression among young adults, with limited differences across sociodemographic characteristics. Higher cigarette prices can prevent smoking initiation and progression; however, complementary interventions are needed to reduce initiation and progression among subgroups disproportionately affected by tobacco.

Young adult e-cigarette use: A latent class analysis of device and flavor use, 2018-2019

ObjectiveThe myriad of e-cigarette devices and flavors used by young adults (YAs) complicates identification of the particular e-cigarette products that are associated with more frequent tobacco use and merit consideration for regulation. The current study used latent class analysis to identify distinct patterns of e-cigarette device and flavor use and evaluate their association with vaping and smoking frequency. MethodsCross-sectional survey data (2018–2019) from a Southern California cohort were analyzed. YAs reporting past 30-day nicotine vaping (N = 550; M age = 19.2 years) self-reported e-cigarette device type/brand and flavor. Six device (e-cig/vape pen, mech mod, box mod, JUUL, non-JUUL pod, disposable) and three flavor (tobacco, mint/menthol, sweet/fruit) indicators were included in a latent class analysis. Past 30-day nicotine vaping and cigarette smoking frequency were assessed as correlates of device and flavor class membership. ResultsThree classes were identified: Any Pod–Mint/Menthol or Sweet/Fruit Flavor Users (prevalance:47%); Non-JUUL–Sweet/Fruit Flavor Users (28%); and Poly-Device–Poly-Flavor Users (25%). Greater frequency of vaping and smoking were associated with higher odds of belonging to the Poly-Device–Poly-Flavor Users class vs. the Any Pod–Mint/Menthol or Sweet/Fruit Flavor Users (vaping: aOR[95%CI] = 1.36[1.16, 1.59], p < .001; smoking: aOR[95%CI] = 1.25[1.02, 1.54], p = .03) and Non-JUUL–Sweet/Fruit Flavor Users (vaping: aOR[95%CI] = 1.30[1.10, 1.53], p < .01; smoking: aOR[95%CI] = 1.42[1.07, 1.88], p = .02) classes. ConclusionsAlthough YAs that predominately used pod devices alongside non-tobacco flavors were most common, YAs characterized by a proclivity toward using many different devices and flavors were appreciably prevalent and smoked and vaped more frequently. Regulations targeting a wide spectrum of vaping products may be optimal in protecting YA health.

Protective Effects of Parental Education Against Youth Cigarette Smoking: Diminished Returns of Blacks and Hispanics.

BackgroundHigh parental educational attainment is protective against youth health risk behaviors such as tobacco use. According to the Marginalization-related Diminished Returns (MDRs) theory, however, higher parental education is less protective for marginalized groups relative to non-Hispanic Whites.ObjectiveTo explore race/ethnic differences in the effects of parental educational attainment on cigarette smoking in a national sample of American adolescents.MethodsIn a cross-sectional study, we used baseline data of 10,878 American youth who had participated in the Population Assessment of Tobacco and Health (PATH 2013). The independent variable was parental educational attainment. The dependent variables were lifetime cigarette smoking, current (past 30-day) cigarette moking, and daily cigarette smoking. Youth age, youth gender, and parental marital status were the covariates. Race/ethnicity was the moderating variable. Logistic regression model was used for data analysis.ResultsOverall, a higher parental educational attainment was associated with a lower lifetime cigarette smoking, current (past 30-day) cigarette smoking, and daily cigarette smoking. Parental educational attainment showed significant interaction with race/ethnicity suggesting smaller protective effects of parental educational attainment on youth tobacco outcomes for Black and Hispanic than for non-Hispanic White youth.ConclusionFor American youth, race/ethnicity limits the health gains that are expected to follow parental educational attainment. While high parental educational attainment is protective against smoking overall, non-Hispanic Whites (the most socially privileged group) gain most and Blacks and Hispanics (the least socially privileged groups) gain least from such resource. In addition to addressing low SES, researchers and policymakers should identify and address mechanisms by which high SES minority youth remain at risk of tobacco use.

Trends and Associations of Menthol Cigarette Smoking Among US Middle and High School Students-National Youth Tobacco Survey, 2011-2018.

Youth cigarette smoking decreased significantly over the last two decades in the United States. This study provides estimates and trends from 2011 to 2018 and factors associated with youth menthol and non-menthol smoking from 2016 to 2018. Using data from the 2011-2018 National Youth Tobacco Surveys, past 30-day (current) menthol and non-menthol cigarette smoking were estimated for all youth (prevalence) and youth smokers (proportions). Trends were examined using Joinpoint regression, calculating the annual percent change (APC). Multivariate logistic regression analyses identified factors associated with menthol smoking. From 2011 to 2018, menthol cigarette smoking among current youth cigarette smokers significantly decreased from 57.3% to 45.7% (APC: -3.0%), while non-menthol (38.2% to 47.3% [APC: 2.9%]) and unknown menthol status (not sure\missing) (4.5% to 7.0% [APC: 7.1%]) significantly increased. Menthol cigarette smoking among high school, male, female, and non-Hispanic white current cigarette smokers decreased, but remained unchanged among middle school, non-Hispanic black, and Hispanic smokers. Significantly higher proportions of menthol cigarette smokers smoked on ≥20 days, ≥2 cigarettes per day, and ≥100 cigarettes in their lifetime compared to non-menthol smokers. Among current cigarette smokers, non-Hispanic blacks, Hispanics, flavored non-cigarette tobacco users, frequent smokers (≥20 days), those smoking 2-5 cigarettes per day, and those living with someone who uses tobacco had higher odds of menthol cigarette smoking. In 2018, nearly half of current youth cigarette smokers smoked menthol cigarettes. While menthol cigarette smoking declined from 2011 to 2018 among all youth and among youth smokers, there was no change in menthol cigarette smoking among non-Hispanic black, Hispanic, and middle school cigarette smokers. This study finds that overall cigarette and menthol cigarette smoking declined in youth from 2011 to 2018. However, menthol cigarette smoking among non-Hispanic black, Hispanic, and middle school youth cigarette smokers did not change. Information from this study can help inform efforts to reduce menthol cigarette smoking among US youth, particularly racial/ethnic minority populations.

PMH52 FACTORS ASSOCIATED WITH REGULAR NICOTINE SALT POD SYSTEM USE AMONG SMOKERS ABSTAINING FROM COMBUSTIBLE CIGARETTES

Previous studies have found a positive association between regular use of Nicotine Salt Pod Systems (NSPS) and abstinence from combustible cigarette use among smokers. This study assessed factors associated with daily use of NSPS among smokers who abstained from cigarette smoking 6 months after initiating NSPS use and those who continued smoking. Adult current smokers (age≥21) who bought an NSPS starter kit and completed baseline and 180-day follow-up assessments (N=18,834) reported demographic characteristics, smoking history and motivations for NSPS purchase at baseline and past 30-day cigarette smoking and NSPS use at 180-day assessment. The sample was stratified by switching (past 30-day abstinence from smoking) status at 180 days; differences in baseline characteristics among daily/non-daily NSPS users in each subgroup were assessed. The sample was divided into independent training and validation sets, and logistic regression models examined associations between baseline characteristics and daily/non-daily NSPS use at 180-days. Among switchers, daily NSPS users (vs. non-daily users) were more likely to be daily smokers, have a smoking history of >10 years, and cite quitting smoking as reasons for purchase. Smoking for >20 years (aOR = 2.7, CI = 1.5-4.9), smoking for 10-20 years (aOR = 1.6, CI = 1.0-2.6), believing NSPS to be less harmful than cigarettes (aOR = 1.4. CI = 1.1-1.8) and daily smoking at baseline (aOR = 1.8, CI = 1.5-2.4) were associated with daily NSPS use at 180-days in the switching subgroup. Logistic models from training samples performed well in validation samples (accuracy scores ranging from 0.68 – 0.73). This study provides new longitudinal data on attributes associated with regular NSPS use among smokers who switch from combustible cigarettes. Identifying factors associated with NSPS use and switching behavior may inform likelihood of behavior change or support development of techniques to aid switching away from cigarettes.
