Hookah use patterns, social influence and associated other substance use among a sample of New York City public university students

BackgroundMost hookah use studies have not included racial and ethnic minorities which limits our understanding of its use among these growing populations. This study aimed to investigate the individual characteristics of hookah use patterns and associated risk behaviors among an ethnically diverse sample of college students.MethodsA cross-sectional survey of 2460 students (aged 18–25) was conducted in 2015, and data was analyzed in 2017. Descriptive statistics were used to present the sociodemographic characteristics, hookah use-related behavior, and binge drinking and marijuana use according to the current hookah use group, including never, exclusive, dual/poly hookah use. Multivariate logistic regression was conducted to examine how hookah related behavior and other risk behaviors varied by sociodemographics and hookah use patterns.ResultsAmong current hookah users (n = 312), 70% were exclusive hookah users and 30% were dual/poly hookah users. There were no statistically significant differences in sociodemographic characteristics except for race/ethnicity (p < 0.05). Almost half (44%) of the exclusive hookah users reported having at least five friends who also used hookah, compared to 30% in the dual/poly use group. Exclusive users were less likely to report past year binge drinking (17%) and past year marijuana use (25%) compared to those in the dual/poly use group (44 and 48% respectively); p < 0.001.ConclusionsThe socialization aspects of hookah smoking seem to be associated with its use patterns. Our study calls for multicomponent interventions designed to target poly tobacco use as well as other substance use that appears to be relatively common among hookah users.

Patterns of electronic cigarette, conventional cigarette, and hookah use and related passive exposure among adolescents in Kuwait: A cross-sectional study.

INTRODUCTIONUse of tobacco products among adolescents is a major global public health concern. Given the changing landscape of tobacco product use and the lack of epidemiologic data to inform tobacco prevention and control strategies in Kuwait, this study sought to estimate the prevalence and patterns of electronic cigarette (e-cigarette), conventional cigarette, and hookah use among adolescents in Kuwait. Moreover, exposure to secondhand smoke (SHS) and secondhand aerosol (SHA) from e-cigarettes was assessed.METHODSThis cross-sectional study enrolled high school students (n=1565; 16–19 years) across Kuwait. Current (past 30-day) use of e-cigarettes, conventional cigarettes, and hookah were assessed through self-reported data. Additionally, current (past 7-day) exposure to SHS and SHA in households and public places were ascertained. Associations were evaluated using Poisson regression, and adjusted prevalence ratios (APRs) and 95% confidence intervals (CIs) were estimated.RESULTSOverall, 26.4% (402/1525), 25.1% (383/1525), and 20.9% (318/1525) of the study participants were current e-cigarette users, conventional cigarette smokers, and hookah smokers, respectively. Current use of any tobacco product was reported by 35.1% (535/1525) of the total study participants. The prevalence of concurrent triple use of ‘e-cigarettes, conventional cigarettes, and hookah’ was estimated to be 12.8% (195/1525). Also, among the study participants, 41.9% (619/1479) were exposed to household SHS, 32.0% (469/1465) were exposed to household SHA, and 62.2% (916/1472) were exposed to SHS and/or SHA in public places. Male adolescents were more likely than females to be current e-cigarette users (APR=5.19; 95% CI: 4.09–6.57), conventional cigarette smokers (APR=5.42; 95% CI: 4.26–6.90), and hookah smokers (APR=3.43; 95% CI: 2.72– 4.32).CONCLUSIONSA substantial proportion of adolescents in Kuwait are currently using tobacco products and being exposed to SHS/SHA. The findings emphasize the need to continue monitoring all forms of tobacco product use among adolescents and to strengthen tobacco prevention and control programs.

Developmental patterns of tobacco product and cannabis use initiation in high school.

To identify prototypical developmental patterns of tobacco product and cannabis use and co-use initiation during adolescence, and determine risk factors for and consequences of these initiation patterns. Prospective repeated-measures cohort with eight semi-annual assessments during high school. Multiple-event process survival mixture modeling identified latent initiation classes with distinct patterns of variation in timing of use initiation of tobacco products and cannabis. We then estimated: (1) associations of baseline risk factors with membership in initiation classes and (2) differences between initiation classes in frequency of cannabis and tobacco product use at the final assessment. Ten high schools in the Los Angeles, CA, USA metropolitan area, 2013-17. Students [1031 (45.4%) males; mean (standard deviation) age at baseline=14.6 (0.39) years] who had never used any tobacco products or cannabis at baseline 9th grade assessment (n=2272). Self-report measures of electronic cigarette (e-cigarette), combustible cigarette, hookah, cigar/cigarillos and cannabis use were collected at each assessment. Four distinct tobacco and cannabis use initiation classes were identified: (1) early and high-risk cannabis and polytobacco initiators (n=116; 5.1%); (2) early cannabis and polytobacco initiators (n=172; 7.6%); (3) late cannabis and e-cigarette initiators (n=431; 19.0%); and (4) abstainers (n=1553; 68.4%). At baseline, older age for the early and high-risk cannabis and polytobacco initiators [odds ratio (OR)=1.22, 95% confidence interval (CI)=1.10, 1.35, P<0.001], peer cannabis use (OR=1.60, 95% CI=1.23, 2.08, P<0.001) and delinquent behavior (OR=1.30, 95% CI=1.08, 1.55, P=0.004) were associated with membership in the three initiation classes (versus abstainers). Membership in the early and high-risk cannabis and polytobacco initiators class (versus three other classes) was significantly associated with increased past 30-day frequency and daily intensity of use at the final assessment (P-values <0.001). Older age, peer cannabis use and delinquent behavior appear to be risk factors for the initiation of tobacco/cannabis product use among high school students in the Los Angeles metropolitan region. Early and higher-risk polyproduct use initiation appears to be associated with greater escalation of past 30-day and daily tobacco and cannabis use at the end of the high school.

Opium and risk of gastrointestinal cancer: a case-control study

Background/aimGastrointestinal (GI) cancers are among the most common cancers in the world. Many risk factors may increase the chance of developing GI cancers. In recent years, a number of epidemiological studies have reported evidence of carcinogenic effects of opium in humans. This study aimed to investigate the relationship between opium use and GI cancer.Materials and methodsThis case-control study was performed on 95 patients with GI cancer and 190 healthy individuals (matched for age, sex, place of residence, and smoking) in Rafsanjan, Iran, in 2018. Diet information, as well as history of smoking, the use of hookah, opium, and its derivatives was collected using a checklist in interview sessions. Conditional logistic regression was performed to investigate the proposed relationship and to estimate odds ratios (OR).Results After adjusting the confounding variables, the use of opium was significantly associated with an increased risk of GI cancer development (OR = 5.95, 95% CI: 2.4–14.9). Also, a dose-response association was found between the cumulative use of opium and the risk of GI cancers. Consumption of fruit and vegetables reduced the risk of developing GI cancers in opium users (OR = 4.9 and 4.7, respectively).Conclusion Opium, in the form used among drug users in this area, can lead to an increased risk of GI cancers. Fruit and vegetables have a protective and modifying effect on the risk of GI cancer development caused by opium consumption.

Exposure and engagement with tobacco-related social media and associations with subsequent tobacco use among young adults: A longitudinal analysis

BackgroundThis study examines whether self-reported exposure to cigarette, e-cigarette, cigar, and hookah advertising, and engagement with pro-tobacco and anti-tobacco social media, are associated with past 30-day tobacco use one-year later, among young adults. MethodsData were from two waves of the Marketing and Promotions Across Colleges in Texas study, a multi-wave study of two- and four-year Texas college students (N = 3947; M age = 23.3, SD = 2.3; 64% female; 35% white, 31% Hispanic, 19% Asian, 8% African-American/black, 7% multi-racial/other) from 24 urban-area schools. Multiple logistic regression examined longitudinal associations between recall of exposure and engagement at baseline (wave 6, spring 2017) and tobacco use at one-year follow-up (wave 7, spring 2018), accounting for baseline demographic characteristics and tobacco use. ResultsSelf-reported exposure to and engagement with tobacco-related social media were significantly associated with past 30-day use of e-cigarettes, cigars, and hookah at one-year follow up; engagement was also associated with cigarette use. Controlling for other social media, exposure to any product advertising via Reddit increased risk for e-cigarette use (AOR = 1.92 [95% CI: 1.17–3.14]). Pinterest exposure increased risk for cigar use (2.92 [1.24–6.85]). Snapchat exposure increased risk for hookah use (2.94 [1.70–5.11]). Pro-tobacco engagement increased risk for future use of all products (1.77 [1.29–2.42]). Anti-tobacco engagement increased risk for use of cigars (1.59 [1.12–2.27]) and hookah (1.69 [1.27–2.25]). ConclusionsFindings demonstrate that encountering tobacco-related social media is an important risk factor for future tobacco use among young people. Social media should be a focus of federal regulation, counter-marketing and health communication campaigns, and intervention.

High Prevalence of Tobacco Product and E-Cigarette Use among Electronic Dance Music Party Attendees

Background: Electronic dance music (EDM) party attendees are at high risk for use of various illegal drugs; however, little is known about their tobacco use. Understanding tobacco use patterns in this population at high risk for illegal drug use can inform multi-product interventions. Objectives: 954 EDM party attendees (ages 18–40) were surveyed in New York City in 2017. We estimated prevalence of use of cigarettes, hookah, cigars, other tobacco, and e-cigarettes and delineated correlates of current (past-month) use using bivariable and multivariable models. Results: Past-month use of cigarettes (36.2%), e-cigarettes (15.6%), cigars (12.5%), and hookah (11.7%) in particular was prevalent. In multivariable models, females were less likely to use e-cigarettes than males (adjusted prevalence ratio [aPR] = 0.63, p = .030), and those who attended graduate school were less likely to use cigarettes (aPR = 0.55, p = .003) and/or e-cigarettes (aPR = 0.33, p = .026). Past-year ecstasy/MDMA/Molly use was a risk factor for past-month use of cigarettes (aPR = 1.38, p = .013) and/or cigars (aPR = 1.61, p = .032), and past-year cocaine use was a risk factor for past-month use of cigarettes (aPR = 1.80, p < .001), cigars (aPR = 1.80, p = .013), other tobacco products (aPR = 3.05, p = .003), and/or e-cigarettes (aPR = 2.39, p = .003). 55.4% of ecstasy users and 60.3% of cocaine users were current cigarette smokers, but use of other products among users of these drugs was less prevalent (9.8–27.9%). Conclusions: Results suggest that current tobacco use is prevalent in this population who is also at high risk for use of drugs such as ecstasy and cocaine. Prevention and cessation efforts need to target tobacco users in this scene while incorporating components addressing illegal drug use.

Smoking Water-Pipe, Opium Use and Prevalence of Heart Disease: A Cross-sectional Analysis of Baseline Data from the Pars Cohort Study, Southern Iran.

Associations between hookah and opium use and an increased risk of ischemic heart disease (IHD) have been suggested in a few studies, but more research is needed on the nature of these associations. We aimed to investigate the association between hookah and opium use and the prevalence of IHD in a population with relatively high prevalence of these exposures in Iran. Using baseline data from the Pars Cohort Study (PCS), a prospective study of individuals aged 40-75 years in Fars province, southern Iran, we calculated adjusted and crude odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the independent association of hookah and opium use with prevalence of IHD. Of 9248 participants, 10.2% (95% CI: 9.5, 10.9) had self-reported IHD. Prevalence of ever use of hookah and opium was 48.9% (95% CI: 44.6, 53.6) and 10.2% (95% CI: 8.3, 12.5) among those with IHD, and 37.0% (95% CI: 35.7, 38.3) and 8.1% (95% CI: 7.5, 8.7) among those without IHD, respectively. Adjusted OR for the association with prevalence of IHD was 1.26 (95% CI: 1.08, 1.46) for hookah use and 1.71 (95% CI: 1.30, 2.24) for opium abuse. No dose-response association was found between hookah and prevalence of IHD. Hookah and opium abuse were associated with prevalent IHD in this study. Although more research is needed on these associations, particularly in prospective settings, reducing hookah and opium use could potentially reduce IHD risk.

Patterns of Tobacco Use and Related Protective Factors Among Somali Youth in the United States.

Anti-smoking norms and educational aspirations are established tobacco prevention targets for general United States (U.S.) adolescent populations but protective factors remain poorly characterized for Somali-American youth. Here we describe patterns of past 30-day tobacco use and associated protective factors among eighth, ninth, and eleventh grade Somali adolescent respondents (n = 2009) to the 2016 Minnesota Student Survey using multivariate logistic regressions. E-cigarette (5.7%) and hookah (5.0%) use were most prevalent. Male youth reported higher levels of tobacco use across products. Adjusted odds ratios showed that internal developmental assets (e.g., e-cigarettes aOR 0.37, 95% CI 0.37, 0.79) and parental anti-smoking norms (e.g., e-cigarettes aOR 0.19, 95% CI 0.09, 0.38) protected against use of all tobacco products. E-cigarettes and hookah are prevalent among U.S. Somali youth, highlighting the need for prevention efforts that address emerging tobacco products and leverage protective factors such as internal assets and parental anti-smoking norms.

Longitudinal pathways of exclusive and polytobacco hookah use among youth, young adults and adults in the USA: findings from the PATH Study Waves 1–3 (2013–2016)

Development of a Hookah Smoking Obscenity Measurement Scale for Adolescents.

BackgroundThe worldwide trend of hookah use among adolescents is increasing, and literature shows a relationship between obscenity and adolescents’ tendency toward hookah smoking. As there is a lack of appropriate instruments to measure the obscenity of hookah smoking, in the present study, we aimed to develop an instrument to measure hookah smoking obscenity among adolescents.MethodsIn this methodological study, a sequential exploratory design was used to conduct the study from February 2017 to July 2018 on adolescents in Tabriz, Iran. In the qualitative phase, we conducted semi-structured individual interviews (with 18 students) and a focus group discussion (FGD) (with 13 students) to explain the concept of obscenity and develop the items of hookah smoking obscenity scale (HSOS). We then examined the psychometric properties of the HSOS based on face, content, construct and predictive validities as well as internal consistency and repeatability.FindingsThe HSOS was developed with 21 items based on the results of qualitative data analysis. Applying confirmatory factor analysis (CFA), the χ2/degree of freedom (df) ratio was found to be 3.792 for the four-factor structure of the questionnaire and the fit indices of this structural model were satisfactory. The values of Cronbach’s alpha and the intraclass correlation coefficient (ICC) for the constructs in the HSOS ranged 0.81-0.93 and 0.79-0.92, respectively.ConclusionWe found the HSOS with a good level of fit indices, validity, and reliability. The HSOS may be applied by school healthcare providers and health practitioners to find valid and reliable data on the obscenity of hookah smoking when developing hookah smoking prevention/cessation interventions among adolescents.

Data Visualization Tools of Tobacco Product Use Patterns, Transitions and Sex Differences in the PATH Youth Data.

Evaluations of multiple tobacco product use and temporal changes in patterns of use are complicated by a large number of combinations and transitions. Visualization tools could easily identify most common patterns and transitions. Set intersection bar plots describe ever use of five tobacco products among 12-17 years old youth in wave 1 of the Population Assessment of Tobacco and Health (PATH) study (N = 11 497). Heat maps visualize unweighted frequencies of transitions from ever use at wave 1 (2013-2014) to past 12-month use at wave 2 (2014-2015). Weighted calibrated heat maps assess differences in relative frequencies of transitions by pattern at wave 1 and identify differences in transitions by sex. The most common tobacco product ever use patterns in wave 1 were of cigarettes only, e-cigarettes only or hookah only, followed by ever use of both cigarettes and e-cigarettes. Initiation of use between waves was uncommon. The most frequent transition among those who reported use at wave 2 but not at wave 1 (N = 971) was to e-cigarette use (N = 301). However, among e-cigarette-only ever users at wave 1 (N = 260), about half did not report any product use at wave 2. Use of three or more products remained stable. Adolescent girls compared to boys appeared more likely to report hookah use at both waves. Set intersection bar plots and heat maps are useful for visualizing tobacco product use patterns and transitions, especially for multiple products. Both techniques could identify common problematic tobacco use patterns across and within populations. Given the growing complexity of the youth tobacco use landscape, approaches to efficiently communicate patterns of multiple tobacco product use should be used more often. This study introduces set intersection bar plots and modified versions of heat maps to the tobacco product literature and illustrates their use in the PATH youth sample. These techniques are useful for visualizing absolute and relative frequencies of multiple possible patterns and transitions. They also suggest targets for subsequent statistical inference such as sex differences in hookah use. The methods can be applied more generally for data visualization wherever large number of combinations occurs.

Initial use of tobacco or marijuana and later use profiles in young adults.

INTRODUCTIONGiven the relatively limited literature regarding risk factors for progression of alternative tobacco and marijuana use, this study examined initially-used tobacco or marijuana products and psychosocial risk factors such as adverse childhood events (ACEs), mental health (depression, ADHD), and parental substance use, in relation to young adult lifetime and current (past 30-day) tobacco and marijuana use.METHODSUsing cross-sectional data from a 2014–2016 study of 3418 young adult college students in Georgia, we analyzed lifetime and current use of various tobacco products (cigarettes, cigar products, smokeless tobacco, e-cigarettes, hookah) and marijuana among lifetime tobacco or marijuana users (N=1451) in relation to initially-used product as well as sociodemographic characteristics and psychosocial risk factors.RESULTSMultivariable analyses indicated that more products ever used correlated with cigarettes being first used (vs cigars, B=-0.66; e-cigarettes, OR=-1.33; hookah, B=-0.99; and marijuana, B=-1.05; p<0.001), as well as being older (B=0.06), male (B=-0.72) and White (vs Black, B=-0.30; or Asian, B=-0.60), more adverse childhood events (ACEs, B=0.07), and parental marijuana use (B=0.47; p<0.05). Currently-used products correlated with cigarettes being first used (vs cigars, B=-0.18; e-cigarettes, B=-0.37; and hookah, B=-0.18; p<0.05), being younger (B=-0.04), male (B=-0.15), more depressive symptoms (B=0.01), and parental marijuana use (B=0.40; p<0.05). Current cigarette, smokeless tobacco, hookah and marijuana use demonstrated specificity to initially-used products.CONCLUSIONSInitially-used products, specifically cigarettes, with well-documented and communicated risks, correlated with using more products subsequently among young adults, underscoring needed research on such risks and risk communication, and early intervention strategies.

Transitions across tobacco use profiles among adolescents: results from the Population Assessment of Tobacco and Health (PATH) study waves 1 and 2.

To estimate progression to polytobacco use (PTU) over 1year among a sample of US youth. Prospective survey with two waves 1year apart: wave 1 (2013-14) and wave 2 (2014-15). We conducted latent transition analysis (LTA) to identify latent class transitions and examine socio-demographic predictors of transition types. United States. A total of 11, 996 people who were aged 12-17 years at wave 1. Publicly available data were used from the Population Assessment of Tobacco and Health (PATH) study, a nationally representative sample of US civilian, non-institutionalized population aged 12 years and older. Tobacco use status was assessed and classified in terms of: never use, non-current (not in the past 30 days) and current (past 30-day) use of cigarettes, cigars, e-cigarettes, hookah and smokeless tobacco. Other nicotine products were excluded because rates of use were either too low to model (e.g. pipe) or the product was not assessed in the PATH youth sample (e.g. nicotine replacement products). We identified three distinct patterns: class 1, non-use (wave 1 prevalence=86%; wave 2 prevalence=78%); class 2, ever use of cigarettes and e-cigarettes (wave 1 prevalence=11%; wave 2 prevalence =14%); and class 3, current PTU (wave 1 prevalence=4%; wave 2 prevalence=7%). Probability of progression from non-use to ever use of cigarettes and e-cigarettes was 0.06 and ever use of cigarettes and e-cigarettes to current PTU was 0.32. Non-users were more likely to transition to ever use of cigarettes and e-cigarettes if they were older (versus younger), white (versus non-white) or if their parental education level was high school or less (versus more than high school); and ever users of cigarettes and e-cigarettes to current PTU if they were older, male or white. US youth who had previously tried e-cigarettes and cigarettes at wave 1 (2013-14) had a 32% chance of transitioning to current use of two or more tobacco products within 1year.

Who Uses Tobacco Products? Using Peer Crowd Segmentation to Identify Youth at Risk for Cigarettes, Cigar Products, Hookah, and E-Cigarettes

Background: Understanding which adolescents are at greatest risk for cigarettes and other tobacco products is critical to inform tailored and targeted interventions. Objectives: We used peer crowds (macro-level subcultures) to identify subgroups of adolescents at-risk for using and being open to using cigarettes; cigars, cigarillos, and little cigars (cigar products); hookah; e-cigarettes; any tobacco product; and multiple products. Methods: In 2017, youth ages 12-17 in five U.S. states completed cross-sectional surveys (n = 1,167). Participants provided data on cigarette use (experimentation) and openness to use (susceptibility); cigar product, hookah, and e-cigarette use (ever use) and openness to use (curiosity); and identification with five peer crowds (Alternative, Country, Hip Hop, Mainstream, Popular). We used chi-square tests to compare rates by peer crowd, and multivariate logistic regressions to assess odds of use and openness for each crowd (reference: Mainstream). Results: Risk differed by peer crowd. Hip Hop youth reported high rates of use, ranging from 12.8% (cigarettes) to 33.4% (e-cigarettes). Regressions revealed increased odds of use for Hip Hop compared to Mainstream for all products, especially cigar products and multi-product use. Popular (cigar products, e-cigarettes) and Alternative (cigarettes) demonstrated increased odds of use compared to Mainstream. We also observed elevated odds of cigarette openness among Alternative, Country, and Hip Hop youth, and of hookah openness among Hip Hop and Popular youth compared to Mainstream. Conclusions/Importance: Peer crowd-tailored cigarette education campaigns can be extended to address other tobacco product risk, especially for higher-risk peer crowds such as Hip Hop.

Androgenetic Alopecia: Relationship to Anthropometric Indices, Blood Pressure and Life-Style Habits.

PurposeThe association of androgenetic alopecia (AGA) with cardiovascular risk factors including hypertension, smoking and high body mass index (BMI) has been investigated in several studies. However, the results are discrepant. The aim of the present study was to evaluate the association of AGA with anthropometrics, blood pressure and lifestyle habits.Patients and MethodsIn this case-control study, 256 men with AGA and 256 age-matched healthy controls were evaluated. Systolic and diastolic blood pressures, as well as anthropometric indices were measured. Data on lifestyle habits including smoking, hookah use and alcohol consumption were also collected.ResultsPatients with AGA had significantly lower BMI and lower waist to hip ratio as compared to controls (p = 0.012 and p = 0.002, respectively). Other anthropometrics as well as mean systolic and diastolic blood pressures were not significantly different between the two groups. There was no significant difference between patients and controls in terms of lifestyle habits. Patients with severe AGA (Norwood-Hamilton classification type IV-VII) had significantly higher systolic and diastolic blood pressures as compared to those with mild to moderate AGA (Norwood-Hamilton classification type II, III), but the mean age of the former group was also significantly higher (p < 0.001).ConclusionIn contrast to some previous studies, our findings did not show a significant association between certain cardiovascular risk factors (such as hypertension and smoking) and AGA. Although lower BMI and lower waist to hip ratio were observed in the patient group, these values were within normal limits and therefore not biologically significant.

The effect of college attendance on young adult cigarette, e-cigarette, cigarillo, hookah and smokeless tobacco use and its potential for addressing tobacco-related health disparities

The goal of this study was to assess the effect of college attendance on tobacco use among young adults and across subpopulations with disparities in tobacco use. Using a cohort of US youth (<18 years) who aged into young adulthood (18–24 years) in the Population Assessment of Tobacco and Health (2013–14, 2015–16, n = 3619) and propensity score matching we estimated the effect of college attendance on past 30-day use of cigarettes, e-cigarettes, cigarillos, hookah and smokeless tobacco. In unmatched analysis, college attenders (vs. nonattenders) had lower risk of using any form of tobacco (Risk Difference (RD): −10.0; 95% CI: −13.2, −7.0), cigarettes (RD: −13.0; 95% CI: −15.4, −10.5), e-cigarettes (RD: −4.1; 95% CI: −6.8, −1.7), cigarillos (RD: −5.7; 95% CI: −7.6, −3.8), and smokeless tobacco (RD: −2.0; 95% CI: −3.4, −0.6), but not hookah (RD: −0.2; 95% CI: −2.1, 1.6). In matched analysis, these associations were all near-null, with the exception of cigarettes (matched RD: −7.1; 95% CI: −10.3, −3.9). The effect of college attendance on cigarette smoking was stable for all subpopulations we assessed including among those identifying as non-Hispanic Black or Lesbian, Gay or Bisexual as well as among those living in the South, Midwest or whose parents did not attend college. The results suggest that college attendance may reduce young adults' risk of cigarette smoking but may not reduce the risk of using other tobacco products.

Effect of risk messages on risk appraisals, attitudes, ambivalence, and willingness to smoke hookah in young adults

ABSTRACT Objective: We examined effects of hookah tobacco risk messages on risk appraisals, attitudes towards hookah, ambivalence about hookah use, and willingness to smoke in young adults aged 18–30 years (n = 234). Design: In an online experiment, participants completed pre-exposure measures and were randomized to hookah tobacco risk messages or to a no message control condition. Main Outcome Measures: Risk appraisals, attitudes, ambivalence, and willingness to smoke hookah. Results: Those who viewed risk messages reported greater risk appraisals (M 4.50, SD 1.17 vs. M 3.87, SD 1.16, p < .001), less positive attitudes (M −0.56, SD 1.24, vs. M 0.39, SD 1.35, p < .001), greater ambivalence (M 3.86, SD 1.26, vs. M 3.08, SD 1.32, p < .001), and less willingness to smoke than controls (M 4.48, SD 1.27, vs. M 4.85, SD 1.37, p = .034). Structural equation modeling demonstrated messages reduced willingness to smoke by evoking less positive attitudes (b = −0.15, 95% CI −0.32, −0.05) and by the effect of heightened risk appraisals on less positive attitudes (b = −0.14, 95% CI −0.30, −0.07). Conclusions: Honing messages and understanding their mechanisms of action are necessary to produce more effective interventions to address hookah and other tobacco use in young adults.

Results of a Single Arm Pilot Study of a Mobile Messaging Intervention for Hookah Tobacco Cessation in Young Adults.

Background:Hookah tobacco use is common among young adults. Unlike cigarette smoking, there is limited evidence on mobile (ie, mHealth) interventions to promote cessation.Objectives:This pilot study tested the preliminary effects of mobile messaging for cessation in young adult hookah smokers.Methods:Young adults (N = 20) aged 18 to 30 years who smoke hookah at least monthly and have done so at least once in the past 30 days received a 6-week mHealth multimedia messaging (text and images) intervention. Message scheduling (2 days/week × 6 weeks) was based on the literature. Content was developed iteratively by the study team and focused on health harms and addictiveness of hookah. Content was individually tailored by baseline hookah use frequency, risk beliefs, and responses to interactive text messages assessing participants’ hookah tobacco use behavior and beliefs to maximize impact. Engagement was assessed during the intervention, and we examined effects on risk perceptions, risk beliefs, and risk appraisals, motivation to quit, and behavior change immediately post-intervention.Results:Participants responded to 11.5 (SD = 0.69) of 12 text message prompts on average, endorsed high message receptivity (M = 6.1, SD = 0.93, range = 1-7), and reported the messages were helpful (M = 8.5, SD = 1.5, range = 1-10). There were significant (P < .05) increases in risk perceptions (d’s = 0.22-0.88), risk appraisals (d = 0.49), risk beliefs (d = 1.11), and motivation to quit (d = 0.97) post-intervention. Half of participants reported reducing frequency of hookah use (20%) or quitting completely (30%) by end of treatment.Conclusions:These pilot results provide preliminary support for an mHealth messaging intervention about risks of hookah tobacco for promoting cessation. Rigorously examining the efficacy of this promising intervention is warranted.

Knowledge and risk perception of e-cigarettes and hookah amongst youths in Lagos State, Nigeria: An exploratory study.

Limited research exists describing young people's knowledge and risk perception of e-cigarettes and hookah in Nigeria. This qualitative study explored the knowledge and risk perception of e-cigarettes and hookah amongst young people in Lagos, Nigeria. Participants (n = 20), aged 15-24 years who had used e-cigarettes or hookah at least once in the past 12 months, participated in three focus group (FG) discussions in January 2020. Each FG session consisted of 6-7 participants, was facilitated by a trained moderator and lasted approximately 60 min. Sessions were recorded, and notes were taken after informed consent. Recordings were transcribed verbatim and analysed using NVIVO 10 software. An essential element of our findings was that the majority of the participants seemed to be more aware of hookah and used hookah compared to e-cigarettes. The participants mentioned they used these tobacco products mainly to reduce stress, for pleasure and for social acceptance. Most of the study participants reported that they were aware of some adverse health effects associated with e-cigarette or hookah use. Although some participants felt that the use of e-cigarettes or hookah could transform to cigarette smoking, many felt that e-cigarette was a harm reduction tool. Young users of e-cigarettes and hookah continue to use these products though they are aware of some associated adverse health effects. These products are used primarily for relieving stress and for social reasons. Raising awareness of the risks associated with the use of these tobacco products may help to reduce the acceptability of these products amongst youths.
