College students' perceptions and knowledge of hookah use

Factors associated with transitions in tobacco product use states among young adults aged 18-29 years

BACKGROUND AND OBJECTIVES

This study examined young adults' tobacco use transitions based on their past 30-day use states, and identified factors associated with their transitions.

METHODS

Participants (N = 12377) were young adults aged 18-29 years at Wave 1 of the Population Assessment of Tobacco and Health (PATH) study. Self-reported tobacco use states were categorized by the number of past-month use days (0, 1-4, 5-8, 9-12, 13-30 days) for cigarettes, electronic cigarettes [e-cigarettes], traditional cigars, filtered cigars, cigarillos, smokeless tobacco (SLT), and hookah. Multistate Markov models examined transitions between use states across Waves 1-5 of unweighted PATH data and multinomial logistic regressions examined predictors of transitions.

RESULTS

Most young adults remained nonusers across adjacent waves for all products (88%-99%). Collapsed across waves, transitioning from use at any level to nonuse (average 46%-67%) was more common than transitioning from nonuse to use at any level (average 4%-10%). Several factors that predicted riskier patterns of use (i.e., transitioning to use and/or remaining a user across adjacent waves) were similar across most products: male, Black, Hispanic, lower education levels, and lower harm perceptions. In contrast, other factors predicted riskier patterns for only select products (e.g., e-cigarette and SLT use among Whites).

DISCUSSION AND CONCLUSIONS

Few sampled young adults escalated their tobacco use over time, and escalations for many products were predicted by similar factors.

SCIENTIFIC SIGNIFICANCE

Prevention and regulatory efforts targeted towards adolescents should continue, but also be expanded into young adulthood. These same efforts should consider both shared and unique factors that influence use transitions.

College students' knowledge about opioids and implications for the opioid crisis

OBJECTIVE

This study assessed undergraduate unhealthy substance use, levels of knowledge about opioid pharmacology, unhealthy use and safety, and students' perceptions about their level of knowledge.

PARTICIPANTS

Participants were undergraduate students at a large, private university in the Northeast.

METHODS

This study employed a cross-sectional study design using an online survey. A convenience sample of undergraduate students (N = 317) described their actual and perceived levels of opioid knowledge and their self-reported substance use.

RESULTS

Objective answers to quiz-style questions about opioids showed knowledge deficits. Participants rated themselves as slightly less knowledgeable than the "average student." Ten percent of students surveyed had used opioids unhealthily at some point in their lifetime. Those reporting unhealthy opioid use had higher subjective and objective opioid knowledge scores.

CONCLUSIONS

University students' subjective and objective knowledge of opioids warrants more effective and engaging substance use education on college campuses.

Spatial Clustering of Hookah Lounges, Vape Shops, and All Tobacco Retailers Near Colleges

INTRODUCTION

US college students smoke hookah and vape nicotine at higher rates than other young adults. Density and/or proximity of hookah lounges and vape shops near colleges has been described, but this study is the first to test whether tobacco retailers spatially cluster near college campuses.

AIMS AND METHODS

We created and linked spatial shapefiles for community colleges and 4-year colleges in California with lists of hookah lounges, vape shops, and licensed tobacco retailers. We simulated 100 datasets, placing hookah lounges, vape shops, and tobacco retailers randomly in census tracts in proportion to population density. A modified version of Ripley's K-function was computed using the radius (r) from each retailer within retail category.

RESULTS

In 2018-2019, 50.5% of hookah lounges (n = 479), 42.5% of vape shops (n = 2467), and 42.0% of all tobacco retailers (n = 31 100) were located within 3 miles of a community college. Spatial clustering was significant (p < .05) from at least 0.4 miles for hookah lounges, 0.1 mile for vape shops, and 0.3 miles for all tobacco retailers. For 4-year colleges, approximately 46.8% of hookah lounges, 31.3% of vape shops, and 31.6% of all tobacco retailers were located within 3 miles. Clustering was significant from 0.2 miles for hookah lounges and 1.3 miles for all tobacco retailers but was not significant for vape shops.

CONCLUSIONS

Evidence that some types of tobacco retailers cluster near community colleges and 4-year colleges implies greater accessibility and exposure to advertising for students. It is also concerning because a higher probability of underage tobacco sales presumably exists near colleges.

IMPLICATIONS

Prior studies infer that hookah lounges and vape shops cluster near colleges from the density and closer proximity to campuses. This study modified a traditional test of spatial clustering and considered community colleges separately from 4-year universities. Spatial clustering of hookah lounges and all licensed tobacco retailers was evident near both types of campuses, but vape shops clustered only near community colleges. Place-based strategies to limit tobacco retail density could expand state and local laws that prohibit tobacco sales near schools to include retailers near college campuses. In addition, college environments should be a target for reducing hookah smoking and nicotine vaping.

Health Information on Waterpipe Lounge Menus to Educate Young Adults: Pilot Study Findings

BACKGROUND

For years, tobacco risk communication has largely focused on cigarette smoking. New strategies must be developed to adapt to emerging tobacco products, such as waterpipe tobacco smoking (WTS).

AIMS

The purpose of this pilot study was to determine the preliminary effects of health information on waterpipe lounge menus on the perceptions of harm and risk from WTS and inform future efficacy interventions for health communication (i.e., educating populations on the risks, harms, and health consequences of WTS).

METHOD

Participants aged 18 to 24 years (n = 213) who smoked waterpipe at least monthly were randomized to one of four waterpipe lounge menu groups using a two-by-two experimental design with "warning message" and "nicotine content" as factors.

RESULTS

Those who viewed waterpipe lounge menus that included a warning message had greater perceived relative harm to health and perceived risk of decreased lung function from WTS. Those who viewed waterpipe lounge menus that included nicotine content had greater perceived risk of heart attack from WTS.

DISCUSSION

Participants who were exposed to health warnings of WTS and information on the nicotine content of waterpipe tobacco increased on measures of perceived relative harm and risk of health consequences.

CONCLUSION

The pilot test results indicate promise for providing health information on waterpipe lounge menus to educate young adults on the harms and risks of WTS.

A Naturalistic Study of Carbon Monoxide, Heart Rate, Oxygen Saturation, and Perfusion Index in Hookah Lounge Patrons

BACKGROUND

Waterpipe (also known as hookah) smokers are exposed to several toxicants, heavy metals, and carcinogens. This study assessed physiologic data from hookah bar participants in an urban area in Florida. We hypothesized that hookah lounge patrons would have a decreased [Formula: see text] and perfusion index, as well as an increased heart rate and exhaled carbon monoxide (CO) levels upon exiting the bars.

METHODS

Exhaled CO levels, heart rate, pulse oximetry for carboxyhemoglobin, and perfusion index were obtained immediately before entering the hookah lounges and after exiting hookah lounges on a sample size of 200 patrons attending hookah lounges. Averages were then used for Wilcoxon signed-rank tests to assess differences across means.

RESULTS

Combining data from both hookah smokers and concurrent smokers, the mean CO measurements went from 5.7 ppm prior to lounge entry to 66.5 ppm after the lounge visit (P < .001). Conversion to carboxyhemoglobin for all hookah smokers represents an increase from 1.5% to 10.6% (P < .001). Carboxyhemoglobin mean values as measured with pulse oximetry increased from 1.4% prior to the lounge visit to 7.2% after the lounge visit (P < .001). The mean heart rate for the subjects also increased from 90.3 beats/min to 94.2 beats/min (P < .001). [Formula: see text] levels decreased from 98.4% to 97.8% (P < .001). Similarly, the mean perfusion index decreased from 3.1% to 2.7% (P = .002).

CONCLUSIONS

Hookah lounge smokers in the United States are exposed to high levels of CO that have the potential for detrimental health effects, as evidenced by rapid negative changes in physiological parameters. Respiratory therapists should be aware of potential cardiovascular changes in hookah lounge patrons who enter emergency rooms and health facilities due to recent exposures.

Predictors of Vaping Behavior Change in Young Adults Using the Transtheoretical Model: A Multi-Country Study

Electronic nicotine products remain popular among college students. These products contain heavy metals, carcinogens and the addictive substance nicotine. By understanding where students are in their behavior change can help to determine and focus messages and campaigns. The aim of this study was to assess predictors of the Transtheoretical model in college-aged vaping. This study consisted of an online/Ipad delivery of a voluntary survey to 1249 young adults/college students at 5 universities (International and within the U.S.). Data was analyzed using Stata. Regression analysis was performed to assess predictors of the stages in the Transtheoretical Model of behavior change. Our study found that women tended to be further along in the stages of change as compared to their male counterparts. Additionally, the older students were more likely to be in maintenance stage as compared to the younger students. The students who vaped longer tended to not have advance into any of the stages of change besides precontemplation. Understanding where students are in the stages of change can help to inform behavioral message campaigns enabling more focused targeting of messages and efforts to reduce consumption. Electronic nicotine products are highly prevalent on college campuses, both nationally and internationally. The nicotine is addictive and may result in less of a desire or ability to quit as young adults age.

Factors associated with tobacco smoking among Saudi college students: A systematic review

INTRODUCTION

There has been an increase in tobacco smoking among Saudi college students in recent years. However, no study has examined, with a systematic approach, the extent to which specific factors are associated with tobacco smoking among this population.

METHODS

PubMed, ProQuest, CINAHL, and Web of Science were utilized to retrieve studies addressing risk factors associated with tobacco smoking among Saudi college students between 2010 and 2019. After confirming their eligibility criteria, studies were imported to the NVivo software for data collection and synthesis. All included articles were critically appraised, based on a modified STROBE.

RESULTS

Twenty-one out of 300 studies met the eligibility requirements for inclusion. Riyadh was the location, health-related science was the field of study, and male the gender of the population of most of the included studies. Only one study used a longitudinal design based on a theoretical framework, the rest were cross-sectional and lacked theoretical utilization. Four individual and two social factors were established to have a significant relationship with tobacco smoking behavior among college students in four or more studies. Environmental factors were found to be associated with a change in smoking behavior among Saudi college students based on two studies.

CONCLUSIONS

There is a dearth of research in utilizing theoretical frameworks to guide the research in order to propose an intervention program among Saudi college students. Future research should aim to recruit participants from different institutions in the Kingdom of Saudi Arabia (KSA), apply other methodological approaches, test other measurements of tobacco smoking, and utilize a theoretical framework.

Research on Youth and Young Adult Tobacco Use, 2013-2018, From the Food and Drug Administration-National Institutes of Health Tobacco Centers of Regulatory Science

The Tobacco Regulatory Science Program is a collaborative research effort between the National Institutes of Health (NIH) and the Food and Drug Administration (FDA). In 2013, the NIH funded 14 Tobacco Centers of Regulatory Science (TCORS), which serve as partners in establishing research, training, and professional development programs to guide FDA. Each of the fourteen TCORS, and two other NIH-funded research programs, the Center for the Evaluation of Nicotine in Cigarettes (CENIC) and the Consortium on Methods Evaluating Tobacco (COMET), pursued specific research themes relevant to FDA's priorities. A key mandate for FDA is to reduce tobacco use among young people. This article is a review of the peer-reviewed research, including published and in-press manuscripts, from the TCORS, CENIC, and COMET, which provides specific data or other findings on youth (ages 10-18 years) and/or young adults (ages 18-34 years), from 2013 to 2018. Citations of all TCORS, CENIC, and COMET articles from September 2013 to December 2017 were collected by the TCORS coordinating center, the Center for Evaluation and Coordination of Training and Research. Additional citations up to April 30, 2018 were requested from the principal investigators. A scoring rubric was developed and implemented to assess study type, primary theme, and FDA priority area addressed by each article. The major subareas and findings from each priority area are presented. There were 766 articles in total, with 258 (34%) focusing on youth and/or young adults. Findings relevant to FDA from this review concern impact analysis, toxicity, health effects, addiction, marketing influences, communications, and behavior.

IMPLICATIONS

The Tobacco Centers of Regulatory Science, CENIC, and COMET have had a high output of scientific articles since 2013. These Centers are unique in that the FDA supports science specifically to guide future regulatory actions. The 258 articles that have focused on youth and/or young adults are providing data for regulatory actions by the FDA related to the key priority areas such as the addictiveness of non-cigarette products, the effects of exposure to electronic cigarette marketing on initiation and cessation, and the impact of flavored products on youth and young adult tobacco use. Future regulations to reduce tobacco use will be guided by the cumulative evidence. These Centers are one innovative mechanism to promote important outcomes to advance tobacco regulatory science.

Hookah Susceptibility and Transitions Over the First Year of College

OBJECTIVE

There has been a growth in popularity of hookah (or waterpipes) among American college students, despite the health risks. This study investigated factors that predict hookah susceptibility and whether hookah susceptibility predicts hookah initiation and continued use.

METHOD

The study established a cohort of 529 incoming college freshmen (51.6% female) who completed an online survey approximately 1 week before their arrival to a large U.S. university. Students were sent four follow-up surveys throughout the 2016-2017 academic year; 90.5% completed at least one follow-up survey.

RESULTS

A total of 13.2% of the sample had used hookah at baseline and 9.9% initiated hookah use over the course of their freshman year. Among the nonusers who had no hookah susceptibility at baseline, 30.0% came to indicate some susceptibility. Multivariable logistic regression indicated that the personality construct conscientiousness was protective against becoming susceptible, whereas coming from a rural part of the state was a risk factor. Susceptibility predicted both continued use among the baseline ever-users and initiation among the baseline never-users.

CONCLUSIONS

These findings highlight the role of susceptibility in the trajectory of hookah use among U.S. college students.

Perceived Harms of Waterpipe Tobacco Heating Sources Among Young Adult Waterpipe Tobacco Smokers

Background. Waterpipe tobacco smoking is associated with many negative health outcomes due to toxicants produced by heating the tobacco using charcoal or electrical heaters. Little is known about how young adult waterpipe tobacco smokers perceive harms of these heating sources. Aims. To examine young adult waterpipe tobacco smokers' perceived harms of electrical heaters and charcoal to heat waterpipe tobacco. Method. This online cross-sectional study enrolled 18- to 32-year-olds who smoked waterpipe tobacco within the past 30 days. Participants completed measures assessing, for each heating source, amount and knowledge of toxicants released (e.g., carbon monoxide, cancer-causing chemicals), perceived safety, worry about inhaling toxicants, perceived health risk, desire to quit, and intention to smoke in the next month. Question order for knowledge of and perceived harms was counterbalanced for each heating source. Results. Analyses were based on responses from 199 participants. Perceived harms for both heating sources were average to low. Despite some question order effects, participants viewed charcoal as more harmful than electrical heaters. Participants knew more about chemicals released from charcoal than electrical heaters. Greater knowledge of chemicals released by both heating sources correlated positively with perceived harms. Perceived harms were associated with a stronger desire to quit, yet unrelated with likelihood of smoking waterpipe during the next month. Discussion. Many young adult waterpipe tobacco smokers view charcoal as more harmful than electrical heaters, although knowledge about harms for each heating source is poor. Conclusion. Interventions are needed to inform the public about harms of waterpipe heating sources in order to curb use.

Predictors of Hookah Smoking among Women in Bandar Abbas, Southern Iran: A Cross-Sectional Study Based on the Intervention Mapping Protocol

Background: The purpose of this study was to determine the predictors of hookah smoking (HS) among professional HS women in Bandar Abbas, southern Iran using intervention mapping protocol. Methods: The present cross-sectional study is part of a larger study, which was conducted on 332 HS women using a multistage (clustered and randomized) process. Data were collected from October 2018 to August 2019 using a researcher-made questionnaire. Results: Mean age of the participants was 36.1 ± 13.3 years. Ordinal regression model, after the control of confounding variables, showed that attitudes, self-efficacy, habits, and intention were the most important predictors of HS behavior in women (OR = 1.14). The prevalence of HS was 1.76 times higher in women who did not want to quit hookah. Knowledge and Social norms were not associated with the HS behavior. Conclusions: According to the present findings, changing or eliminating women's positive attitude toward HS is deemed possible through reducing the social acceptance of HS in enculturating the negative attitude in society, enhancing women's self-efficacy via purposeful and specific education on resisting hookah temptation, unraveling all factors involved in habit formation and adjusting these factors through long-term interventions and timely interventions to affect intention to consumption before the actual occurrence of behavior (HS).

Evidence of compensation among waterpipe smokers using harm reduction components

OBJECTIVES

We examined two waterpipe tobacco smoking components advertised to reduce harm to determine if they result in lower levels of biomarkers of acute exposure.

METHODS

We conducted a crossover study of 34 experienced waterpipe smokers smoking a research-grade waterpipe in three configurations ad libitum in a controlled chamber: control (quick-light charcoal), electric (electric heating) and bubble diffuser (quick-light charcoal and bubble diffuser). We collected data on smoking topography, environmental carbon monoxide (CO), subjective effects, heart rate, plasma nicotine and exhaled CO and benzene.

RESULTS

Smokers' mean plasma nicotine, heart rate, and exhaled benzene and CO boost were all significantly lower for electric compared with control. However, smokers puffed more intensely and took significantly more and larger volume puffs for a larger total puffing volume (2.0 times larger, p<0.0001) when smoking electric; machine yields indicate this was likely due to lower mainstream nicotine. Smokers rated electric smoking experience less satisfying and less pleasant. For charcoal heating, the mean mass of CO emitted into the chamber was ~1 g when participants smoked for a mean of 32 minutes at a typical residential ventilation rate (2.3 hr-1).

CONCLUSION

Waterpipe smokers engaged in compensation (i.e., increased and more intense puffing) to make up for decreased mainstream nicotine delivery from the same tobacco heated two ways. Waterpipe components can affect human puffing behaviours, exposures and subjective effects. Evidence reported here supports regulation of waterpipe components, smoking bans in multifamily housing and the use of human studies to evaluate modified or reduced risk claims.

Youth perception of harm and addictiveness of tobacco products: Findings from the Population Assessment of Tobacco and Health Study (Wave 1)

PURPOSE

We provide a US national assessment of youth perceptions of the harm and addictiveness of six separate tobacco products, identifying a continuum of perceived harm associated with a range of products in relation to patterns of current use, former use, and susceptibility to use tobacco products.

METHODS

We evaluated youth respondents (N = 13,651) ages 12-17 from Wave 1 (2013-2014) of the Population Assessment of Tobacco and Health (PATH) Study. Analyses (2015-2016) focused on refining measures of perceived harm for each product and delineating youth characteristics (demographic, tobacco use status) associated with beliefs about the harmfulness and addictiveness of tobacco products.

RESULTS

Cigars, hookah and e-cigarettes were each perceived as having significantly lower harm (p's < 0.05) than smokeless products, with the lowest ratings of harmfulness and addictiveness observed for hookah and e-cigarettes (p's < 0.001). Incrementally lower levels of harm and addictiveness perceptions were observed among youth at increasing risk for tobacco use (p's < 0.05).

CONCLUSIONS

Among U.S. youth, lower perceptions of harm and addictiveness of tobacco products were associated with susceptibility to use tobacco and patterns of tobacco product use. Future longitudinal assessments from the PATH Study can provide key information on youth development of perceptions of harm and addictiveness and influences on patterns of tobacco use.

Knowledge, attitudes, and perceptions towards waterpipe tobacco smoking amongst college or university students: a systematic review

BACKGROUND

Despite evidence for the harms of waterpipe tobacco smoking (WTS), its use is increasing amongst college and university students worldwide. This systematic review aims to assess the knowledge of, attitudes towards and perceptions of WTS among college or university students.

METHODS

We electronically searched MEDLINE, EMBASE, CINAHL, PSYCHINFO and ISI the Web of Science in October 2018, restricting our search to studies published since January 1990. We included studies among university or college students that used qualitative or quantitative methods, and addressed either knowledge, attitudes, or perceptions towards WTS. We excluded studies where WTS could not be distinguished from other forms of tobacco use and studies reported as abstracts where the full text could not be identified. Data were synthesised qualitatively and analysed data by region (global north/ south), and by reasons for use, knowledge of health hazards, how knowledge influences use, perceptions towards dependence, and policy knowledge.

RESULTS

Eighty-six studies were included; 45 from the global north and 41 from the global south. Socio-cultural and peer influences were major contributing factors that encouraged students to initiate WTS. Furthermore, WTS dependence had two components: psychological and social. This was compounded by the general perception that WTS is a less harmful, less addictive and more sociable alternative to cigarette smoking. Knowledge of WTS harms failed to correlate with a reduced risk of WTS use, and some students reported symptoms of WTS addiction. A large proportion of students believed that quitting WTS was easy, yet few were able to do so successfully. Finally, students believed current public health campaigns to educate on WTS harms were inadequate and, particularly in the global north, were not required.

CONCLUSION

Reasons for WTS amongst university students are multi-faceted. Overall, interventions at both the individual and community level, but also policy measures to portray a message of increased harm amongst students, are required. Additional studies are necessitated to understand temporal changes in students' beliefs, thus allowing for better targeted interventions.

Imitating waterpipe: Another tobacco industry attempt to create a cigarette that seems safer

INTRODUCTION

The use of waterpipe (also known as hookah) increased between 2011 and 2016 in the US and globally, especially among youth and young adults. The aim of this study is to examine the tobacco industry's interest, involvement and role in proliferating waterpipe-like products and its technology.

METHODS

We searched the University of California San Francisco Truth Tobacco Industry Documents beginning with the search terms "hookah', 'waterpipe', 'narghile', 'shisha', 'hooka', 'e-hookah', 'electronic hookah', 'water filtration', and 'hubble-bubble' and then expanded the search using snowball sampling. Over 1500 documents were reviewed, and 39 were included in this analysis.

RESULTS

This review focuses on several companies' addition of water to the filter of one cigarette holder and to two cigarettes in an attempt to make these products seem safer. In 1954, the Aquafilter Corporation created and patented a filtered cigarette holder named Aquafilter, which the documents reveal was closely monitored by multiple tobacco companies. In 1965, the American Tobacco Company developed the Waterford cigarette. In 1987, Japan Tobacco patented the Rivage cigarette. Waterford and Rivage were very similar products that contained crushable water capsules designed to "wet" the cigarettes' filter.

CONCLUSION

Companies have been attempting to incorporate the water filtrating aspect of waterpipe into cigarette products. Ultimately, several tobacco companies adapted the technology from these devices to create cigarettes with crushable flavor capsules. Given the tobacco industry's history of resurrecting products, the industry may attempt to incorporate water filtration and other aspects of waterpipe into future products to attempt to make them appear safer.

Waterpipe tobacco use in college and non-college young adults in the USA

BACKGROUND

Waterpipe tobacco smoking (WTS or 'hookah') is common among adolescents and college students in the USA. However, there has not yet been a large-scale, nationally representative study independently examining WTS among young adults who are not in college.

OBJECTIVE

This study sought to examine associations between attitudes, normative beliefs, certain socio-demographic factors and current WTS among young adults not in college and compare them to young adults in college.

METHODS

A total of 3131 US adults ages 18-30 completed an online survey about WTS behaviour, attitudes, normative beliefs and relevant socio-demographic factors. Multivariable logistic regression was used to examine independent associations between these variables and current WTS stratified by student status.

RESULTS

Ever WTS was reported by 29% of young adults not in college and by 35% of those in college, and current use rates were 3 and 7%, respectively. Multivariable models demonstrated that positive attitudes and perceived peer acceptability of WTS were significantly associated with increased current WTS for both young adults not in college [adjusted odds ratio (AOR) = 2.72; 95% CI: 2.00-3.71 and AOR = 2.02; 95% CI: 1.50-2.71, respectively] and young adults in college (AOR = 3.37; 95% CI: 2.48-4.58 and AOR = 2.05; 95% CI: 1.49-2.83, respectively). The magnitude of these associations was not significantly different when comparing individuals in college and not in college.

CONCLUSIONS

Among young adults, WTS is common in non-college-based populations as well as in college-based populations. Therefore, prevention programming should extend to all young adults, not only to those in college.

Hookah use as a predictor of other tobacco product use: A longitudinal analysis of Texas college students

INTRODUCTION

Hookah use is particularly prevalent among U.S. college students; however, few studies have investigated whether hookah use is a risk factor for the initiation of other tobacco products. This study examined whether hookah use predicted subsequent initiation of other combustible tobacco products (conventional cigarettes and cigar products) and Electronic Nicotine Delivery Systems (ENDS) among Texas college students during a 2.5-year study period.

METHODS

This study involved a longitudinal analysis of data from Waves 1-6, with 6 months between each wave, of the Marketing and Promotions Across Colleges in Texas Project (Project M-PACT). Two separate multilevel discrete-time survival analyses were used to model the associations between past 30-day hookah use and subsequent initiation of 1) other combustible tobacco products, and 2) ENDS during the 2.5 year study period, after controlling for demographic, other tobacco use, and risk-taking personality characteristics (i.e. sensation seeking and impulsivity).

RESULTS

After controlling for covariates, past 30-day hookah use was associated with significantly higher odds of subsequent initiation of other combustible tobacco products. Past 30-day hookah use also predicted subsequent initiation of ENDS after controlling for covariates.

CONCLUSIONS

This study is one of the first to demonstrate that hookah use is a predictor of subsequent initiation of other combustible tobacco products and ENDS among college students. These findings suggest that hookah may prime individuals to use other tobacco products, which has important implications for prevention programs and future research.

Hookah Use Among College Students: Recent Use, Knowledge of Health Risks, Attitude and Reasons for Use

Notwithstanding the efforts of health educators and other health professionals regarding tobacco and smoking cessation, research indicates that hookah smoking among college students remains a health concern. Research shows an upward trend in college students' hookah use. The purpose of this study was to identify and describe potential patterns/differences in college students' hookah use, and the relations among attitudes toward and knowledge about hookah use and use of this drug. A four-page, 20-item survey was used to collect data from participants (N = 403) and to measure participants 'recent use, knowledge of health risks, attitudes and reasons for hookah use among college students. Results indicated increased prevalence rates (53.8%) among participants of this study. Participants' recent hookah use was consistent with that of current research. Study findings supports current research, which found that college students have low negative perceptions of the health risks (addictive and detrimental properties) of hookah use. Analyses also determined that college students' attitudes toward hookah was associated with use of this drug. Regarding reasons why students may use hookah, data analysis indicated statistical significance in lifetime hookah use based on reasons for use. Study provide information for health educators creating hookah risk awareness educational programs aimed at reducing rates of hookah smoking among college students.

Comparing harm beliefs and risk perceptions among young adult waterpipe tobacco smokers and nonsmokers: Implications for cessation and prevention

Introduction

Very little is known about how waterpipe tobacco smokers and nonsmokers compare on harm beliefs about waterpipe tobacco smoking (WTS) and how these beliefs are related to risk appraisals and intentions to engage in WTS. We investigated these issues among young adult waterpipe tobacco smokers, susceptible nonsmokers, and non-susceptible nonsmokers.

Methods

Young adults ages 18 to 30 who smoked waterpipe tobacco during the last 30 days or never used waterpipe tobacco were recruited online through Turkprime. Nonsmokers were grouped as susceptible or not. Participants completed measures of harm beliefs, risk appraisals (i.e., perceived risks and worry), and desire to quit among smokers or willingness/curiosity to try waterpipe among nonsmokers.

Results

Analyses were based on 247 smokers and 418 nonsmokers. Smokers endorsed most strongly harm beliefs that portrayed WTS as safe, followed by susceptible and then non-susceptible nonsmokers. Most harm beliefs were significantly related to risk appraisals, yet weakly associated with desire to quit or willingness/curiosity to try waterpipe tobacco, except among susceptible nonsmokers.

Conclusions

Greater efforts are needed to correct maladaptive beliefs about WTS harms, especially among smokers. Among susceptible nonsmokers, harm beliefs may be more influential in predicting willingness to try WTS than risk appraisals.

•

Waterpipe tobacco smokers view waterpipe tobacco smoking as safer than nonsmokers.

•

Perceived risk correlates with many harm beliefs about waterpipe tobacco smoking.

•

Among smokers, desire to quit is related more with perceived risk than harm beliefs.

•

Among susceptible nonsmokers, intent to try waterpipe relates to many harm beliefs.

University students' perceived risk of and intention to use waterpipe tobacco

Emerging tobacco product use is increasing. We evaluated factors associated with perceived risk of and intention to use waterpipe tobacco by surveying students at a large university in the southeastern U.S. (N = 667). Proportional odds modeling assessed whether demographic characteristics and social acceptability are associated with perceived risk of waterpipe tobacco use; and if these factors and perceived risk are related to intention to use waterpipe tobacco. Participants who perceived waterpipe tobacco to be more socially acceptable had lower odds of perceiving it as risky (95% confidence interval [CI] 0.50-0.68). Compared with never users, former tobacco users and current users had lower odds of perceiving waterpipe tobacco use as risky (95% CI 0.38-0.80 and 0.28-0.63, respectively). Similarly, students with greater perceived social acceptability scores had higher odds of intending to use waterpipe tobacco (95% CI 1.41-2.63), while those who perceived greater risk had lower odds of intending to use it (95% CI 0.34-0.64). Compared with never users, former users had higher odds of intending to use waterpipe tobacco (95% CI 1.42-7.21). Among those who had ever used waterpipe tobacco, 90% reported 'to socialize' as the most frequent reason for deciding to do so. Findings underscore the need for future prevention efforts.
