Prevalence of and associations with waterpipe tobacco smoking among U.S. university students

Comparisons between young adult waterpipe smokers and nonsmokers' reactions to pictorial health warning labels in Lebanon: a randomized crossover experimental study

This study compares the impact of pictorial health warning labels (HWLs) and their placements on waterpipe parts (device, tobacco and charcoal packages) on health communication outcomes between waterpipe smokers and nonsmokers in Lebanon. An online randomized crossover experimental study was conducted among young adults (n = 403, August 2021) who observed three conditions of HWLs: pictorial HWLs on the tobacco package, pictorial HWLs on all waterpipe's parts and text-only HWL on the tobacco package in random order. Participants completed post-exposure assessments of health communication outcomes after each image. Using linear mixed models, we examined the differences in the effect of HWL conditions on several outcomes (i.e. warning reactions) between waterpipe smokers and nonsmokers, controlling for confounders (i.e. age, sex). Nonsmokers reported greater attention (β = 0.54 [95% confidence interval: 0.25-0.82]), cognitive elaboration (0.31 [0.05-0.58]) and social interaction (0.41 [0.18-0.65]) for pictorial HWLs on the tobacco packages than text-only compared with smokers. Pictorial HWLs on three parts versus one part elicited higher cognitive reactions and perceived message effectiveness in nonsmokers compared with waterpipe smokers. These findings provide valuable information for policymakers about the potential of implementing HWLs specific to waterpipes to prevent their use among young adults and limit tobacco-related morbidity and mortality in Lebanon.

Correlates of motivation to quit waterpipe tobacco smoking among US young adults: implications for cessation interventions

Waterpipe tobacco smoking is a public health concern that poses many of the same health risks as cigarette smoking, especially among young adults-a subpopulation characterized by the highest prevalence of waterpipe tobacco smoking. Nevertheless, it remains understudied relative to other forms of tobacco use. We examined sociodemographic, behavioral and cognitive factors associated with young adults' motivation to quit waterpipe smoking using a theory-informed approach. We completed a secondary analysis of baseline data on waterpipe tobacco smoking beliefs and behavior collected from 349 US young adults aged 18-30 years. We analyzed sociodemographics, tobacco use and cessation behaviors and perceptions, and theory-related constructs associated with motivation to quit waterpipe tobacco smoking using linear regression. Overall, participants reported low motivation (mean = 2.68, SD = 1.56, scale range 1-7) and high self-efficacy (mean = 5.12, SD = 1.79) to quit waterpipe tobacco smoking. In multivariable analysis, prior quit attempts (β = 1.10, P < 0.01), greater perceived risks of waterpipe tobacco smoking (β = 0.42, P < 0.01) and increasingly negative attitudes toward waterpipe tobacco smoking (β = 0.29, P < 0.01) were associated with higher motivation to quit. These findings highlight the importance of those factors as potential cessation determinants. These findings can help guide the development and refinement of interventions targeting young adult waterpipe tobacco smoking.

Estimating the prevalence of high-risk behaviors using network scale-up method in medical university students

BACKGROUND

There is not much information about high-risk behaviors in young groups, especially students. This study was conducted to estimate the prevalence of high-risk behaviors in students of universities of medical sciences in West Azerbaijan Province, Iran, by network scale-up (NSU) method.

MATERIALS AND METHODS

This cross-sectional study was performed on 450 students from the universities of medical sciences. A researcher-developed checklist was used to collect the data. We considered number 16 for the social network size of students according to a previous study. Based on the response of individuals to each of the high-risk behaviors (including cigarette smoking, hookah use, opium consumption, alcohol drinking, tramadol/ecstasy taking, and extramarital sex) in their social network, the prevalence of these behaviors was estimated. The required calculations were performed using the NSU method. Furthermore, 95% uncertainty interval (UI) was calculated using the bootstrap method.

RESULTS

Totally, 196 (44%) participants were male. The mean age (standard deviation) of the participants was 22 ± 2 years. Results showed that hookah use (20% 95% UI [18.9-21.1]) and opium consumption (0.4% 95% UI [0.24-0.6]) had the highest and lowest frequencies, respectively. Cigarette smoking (17% 95% UI [15.8-18]), alcohol use (8.3% 95% UI [7.5-9.1]), extramarital sex (8.2% 95% UI [7.4-9]), and tramadol/ecstasy taking (4% 95% UI [6.4-4.6]) were the next most common high-risk behaviors, respectively.

CONCLUSIONS

Given that hookah use and cigarette smoking are the most common high-risk behaviors in students, especially males, appropriate cultural activities and educational programs should be employed by relevant authorities to reduce these behaviors.

Effects of mental simulation of future waterpipe tobacco smoking on attitudes, perceived harms and intended use among young adults

The desire to engage in waterpipe tobacco smoking (WTS) may occur when smokers and nonsmokers conjure positive mental simulations of WTS. However, effects of these simulations on desire to smoke waterpipe tobacco and potential mediators are unexplored. This research addressed these effects among young adult waterpipe tobacco smokers and nonsmokers. Two online studies were conducted with adults ages 18-30. In Study 1, 200 smokers, 190 susceptible nonsmokers, and 182 nonsusceptible nonsmokers were randomized to mentally simulate or not WTS in the future. In Study 2, 234 smokers and 241 susceptible nonsmokers were randomized to four arms: no simulation or simulations that varied valence of experience (positive, negative or no valence provided). Main outcomes were immediate desire to smoke waterpipe tobacco, cognitive and affective attitudes, and perceived harms. In Study 1, mental simulations increased the desire to smoke waterpipe tobacco among smokers. In Study 2, asking participants to simulate WTS positively or with no valence instruction increased desire to smoke relative to negative valence instruction or no simulation. Negative simulations reduced perceived probability of smoking within a month compared to positive simulations. Effects on desire to engage in WTS were mediated by cognitive and affective attitudes among susceptible nonsmokers and by cognitive attitudes among smokers. These findings suggest that exploring when and how often mental simulations about WTS are evoked and their potency for promoting prevention and cessation of WTS merit further attention.

Psychophysiological responses to hookah tobacco public education messages among young adults

OBJECTIVE

Hookah tobacco use among young adults may be driven by misperceptions of health harms and addictiveness, appealing flavors, and social use. This study examined the effects of hookah prevention messages on participants' cognitive and emotional processing in a lab setting.

METHOD

One hundred twenty participants (61 susceptible never-users, 59 current users) were exposed to messages representing six categories: health risks only, health risks of social use, health risks of flavors, addiction risks only, addiction risks of social use, and addiction risks of flavors. Guided by the Limited Capacity Model of Motivated Mediated Message Processing, participants' psychophysiological responses (heart rate, skin conductance, facial action coding) were recorded while participants viewed the messages. Recognition memory and counterarguing were measured postexposure.

RESULTS

The combination of heart rate, skin conductance, both positive and negative facial action coding, and recognition memory indicated that social themed messages were more defensively processed than the other message types. Addiction-social messages, in particular, were least likely to be encoded. Further, defensive processing indicated by the psychophysiological and recognition data did not vary according to user status. Counterarguing was higher for users than for never-users across all message themes and risks.

DISCUSSION

Messages about health risks and addiction, whether or not they included information on flavors, evoked relatively similar responses. But social themed messages stand out as potentially problematic, especially addiction-social messages. Using psychophysiological and self-report measures extend opportunities to identify optimal hookah tobacco public education message features.

Substance use among adolescents and young adults with chronic kidney disease or kidney failure

Substance use, a significant public health issue, is well described in the adult chronic kidney disease (CKD) population. Knowledge about substance use in the adolescent and young adult (AYA) CKD population such as prevalence, impact on kidney function, medication adherence, and psychosocial well-being remain largely unknown. Awareness of and inquiring about substance use is paramount to providing evidence-based care and preparation to transition to adult-focused health services. The authors in this review identify commonly used substances (alcohol, tobacco, marijuana, etc.) and how they impact kidney function and care of the AYA with CKD or kidney failure. Recommendations for screening and intervention strategies are provided.

Predictors of waterpipe smoking among university students in the Qassim region, Saudi Arabia

INTRODUCTION

Waterpipe smoking has gained global popularity among adolescents and young adults. This study aimed to identify the predictors of waterpipe smoking among university students in the Qassim region of Saudi Arabia.

METHODS

A cross-sectional study was conducted using a pre-tested, validated, and self-administered questionnaire to identify the predictors of waterpipe smoking among university students aged >18 years in the Qassim region.

RESULTS

Of the 1158 questionnaires distributed, 928 were returned with complete responses. Of these 928 participants, 820 were men (88.7%) and the majority were unmarried (95.6%). The risk of waterpipe smoking was significantly higher in students aged >26 years (OR=3.39; 95% CI: 1.30– 8.80), those who had a brother who smoked (OR=1.78; 95% CI: 1.13–2.79), and those who were married (OR=3.21; 95% CI: 1.36–7.59). Furthermore, participants who had smoked cigarettes (OR=3.18; 95% CI: 1.89–5.34) or other tobacco products (OR=6.39; 95% CI: 3.69–11.07) within the past 30 days, and students who believed that waterpipe smoking was less harmful than cigarette smoking (OR=2.61; 95% CI: 1.54–4.41) had a higher risk of engaging in waterpipe smoking. However, the risk was lower among students receiving a monthly financial aid of more than US$264 (OR=0.34; 95% CI: 0.13–0.89).

CONCLUSIONS

This study revealed that higher age, being male, being married, low student financial aid, waterpipe smoker sibling, cigarette and other types of tobacco smoking in the past 30 days, and believing waterpipe smoking to be less harmful than cigarette smoking, were significant predictors of waterpipe smoking. Educational programs targeted at improving awareness of the adverse effects of waterpipe smoking should be considered for early prevention in young adults.

Aspects associated with waterpipe smoking in Iranian youths: a qualitative study

BACKGROUND

Waterpipe is one of the oldest methods of tobacco smoking, which has become the public health challenge, especially in the Eastern Mediterranean countries such as Iran. This study aimed to investigate the waterpipe smoking (WPS) in the young people of Kermanshah in 2020, using a qualitative method.

METHODS

This was a qualitative study conducted with the approach of content analysis. Participants were young waterpipe user aged 17 to 25 years selected by purposeful sampling method in Kermanshah city, located in the west of Iran. Data were collected through semi-structured interviews in face-to-face and audio-recorded methods based on an interview guideline during June to August 2020. Then researchers transcribed verbatim and analyzed the content of the interviews thematically.

RESULTS

In this study, 23 young people who were waterpipe users at the time of the study participated. The results showed that social aspects in three sub-categories were involved in WPS including "socio-cultural aspects", "socio-environmental aspects", and "social relations". Individual aspects of waterpipe use as second category also consisted of two sub-categories including "motivational aspects" and "lack of psycho-protective aspects".

CONCLUSIONS

It seems that the implementation of the policy of reducing access to waterpipe in public environments is effective in reducing waterpipe consumption. It is suggested that educational and interventions, based on targeted models and theories be implemented in order to increase young people's belief and perception on dangers of WPS, and to improve their self-efficacy to smoking cessation.

Cigarette, waterpipe, and electronic cigarette use among college fraternity and sorority members and athletes in the United States

To examine the association between fraternity/sorority membership and athlete status with tobacco use by tobacco product type. Participants: Undergraduate college students who participated in the Spring 2017 National College Health Assessment-II Survey (n = 47,821). Methods: Prevalence of current (past-30 day) cigarette smoking, waterpipe tobacco smoking (WTS), and e-cigarette (ECIG) use was examined. Logistic regressions examined associations between fraternity/sorority membership and participation in collegiate athletics with tobacco use. Results: Fraternity/sorority members had the highest current use rates for cigarettes, waterpipe tobacco, and ECIGs and were nearly twice as likely to report cigarette smoking, WTS, and ECIG use relative to non-fraternity/sorority members. Relative to non-varsity athletes, varsity athletes were less likely to report cigarette smoking and WTS, but not ECIG use. Conclusions: Fraternity/sorority members appear to be at risk for use of multiple tobacco products. Varsity athlete status may be protective for some tobacco products, but does not appear no for ECIG use. ECIGs may appeal to groups typically at low risk for other tobacco products.

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.

Changes in Attitude to Waterpipe Tobacco Smoking among Youngsters in Eastern Province, Saudi Arabia: A Cross-Sectional Study

BACKGROUND

A growing number of epidemiological evidence suggests a significant increase in waterpipe tobacco smoking, and its potential to become a major public health concern in most Arabic countries, including Saudi Arabia.

METHODS

A cross-sectional study was carried out to assess the prevalence of intention to quit among ever users of waterpipe and intention to start among the never users. The study also investigated the barriers that may prevent users from quitting or trigger the nonusers to start waterpipe smoking. The study consisted of 464 university students from Eastern Province, Saudi Arabia.

RESULTS

One hundred and sixty-eight (36.2%) participants were responded that they had WTS at least one time in the past. Among the ever users of WTS, 120 (71.4%) participants had made an attempt or more to quit WTS in the past, 64 (38.1%) had made more than one attempt, and nearly two-third expressed the intention to quit WTS in the future. Forty (13.5%) out of 296 never-users expressed their intention to start WTS in the future. The study further showed that peer influence, social acceptance, and risk perception were significant predictors of intention to start or stop WTS among students.

CONCLUSION

It is promising that substantial users have the intention to discontinue WTS, though a fraction of never users wish to try WTS in the future.<br />.

"It's beyond the pale to smoke hookah": perceptions of Iranian adolescents on social unacceptability of hookah smoking

Introduction

Globally, the popularity of hookah smoking, as a social and entertaining behavior, is increasing among adolescents and youths. The present study aimed to explore the perceptions of high school students on Social Unacceptability (Arabic/Persian term = Qabahat) of Hookah Smoking (SUoHS) in an Iranian context.

Methods

In this qualitative study, 31 student adolescents in Tabriz, Iran, were invited to participate in semi-structured individual interviews and focus group discussions (FGDs). Data were analyzed using interpretative thematic analysis.

Results

The unacceptability of hookah smoking was viewed at the “disreputability of hookah smoking and hookah smokers”. The students also explained SUoHS in the “incivility of hookah smoking and smokers in the society”, “disrespectfulness of hookah smokers and their families”, and “the consequences of hookah smoking”.

Conclusions

The SUoHS is rooted in the social values and norms within communities. To decrease hookah smoking levels among adolescents, school health nursing interventions should be tailored to bridge the gap between their recognition of SUoHS and subsequent behavior change through creating group dynamics highlighting the domains of social unacceptability of the behavior.

Waterpipe Warning Placement and Risk Perceptions: An Eye Tracking Study

Objectives: The purpose of this study was to select a health warning message location on a waterpipe (WP) that both attracted visual attention and conveyed the risks associated with WP smoking. Methods: During June through November 2019, we conducted a within-subjects randomized experiment (N = 74) using eye tracking equipment to examine visual attention to 3 placements of a health warning on the WP (stem, water bowl, hose). We asked young adult ever WP users 3 questions about WP harm perceptions. We used generalized linear mixed models to examine the amount of fixation time spent on the placement locations; we used repeated measures ANOVA to model changes in harm perceptions. Results: There were statistically significant differences across all 3 placement locations; regardless of place, all HWLs attracted a comparable amount of visual attention. Absolute WP harm perceptions significantly increased following the experiment and remained significantly higher at the one-week follow-up, compared to baseline. Conclusions: Warnings on WPs attracted visual attention and increased harm perceptions, and those harm perceptions remained high one week after the experiment. Findings indicate the value of including a warning on the WP device, and underscore the necessity and effectiveness of those health warnings to combat WP harm misperceptions.

Cancer in Lebanon: A Review of Incidence Rates from 2008 to 2015 and Projections Till 2025

Background and Objectives  Cancer carries one of the heaviest burdens globally in terms of mortality. Lebanon is a middle-income Middle East country also plagued with cancer, as such a study and analysis of cancer trends and projections would serve a great benefit in the fight against the disease. Materials and Methods  All data pertaining to cancers in Lebanon were extracted from the National Cancer Registry of Lebanon Web site. Data were analyzed to produce trends over the years of our study (2008-2015). Ten-year projections were further calculated for the top cancers by the primary site using logarithmic models. Results  The top cancers in Lebanon are the breast, lung, colorectal, bladder, and prostate. The top cancers affecting females are the breast, lung, and colorectal. The top cancers affecting males are the prostate, lung, and bladder. Cancer cases are projected to increase in Lebanon over the next 10 years. Conclusion  Lebanon had a steady incidence rate of cancer cases during the time of our study. A more complete understanding of cancer trends and their ultimate reduction will require further research into the origins of specific cancers and the means of prevention and control.

Perceptions of Waterpipe Smoking among Young Adults: A Phenomenological Study

BACKGROUND

Waterpipe tobacco smoking is becoming increasingly popular in the West among young people. Given the associated health risks of this behaviour, we aimed to investigate why young adults take up waterpipe tobacco smoking and their attitudes to the associated risks.

METHODS

This was a qualitative study, with a phenomenological perspective. Focus groups and face-to-face semi-structured interviews were conducted among waterpipe smokers aged 20-30 years living in London, UK. Transcripts were analysed using constant comparison and cycling between the data and analysis. Data collection continued until thematic saturation was achieved.

RESULTS

Sixteen smokers attended focus groups and face-to-face interviews. Seven main themes emerged encompassing four main dimensions relating to: lack of knowledge, perceived risk, affordability, and social addiction. Waterpipe was perceived to be safer than cigarette smoking due to the pleasant odour, fruity flavours, and belief that water filtered the toxins. The waterpipe had become a "social addiction" enhancing group atmosphere, was cheap and did not have the dangers of violence or hallucinations associated with other addictions like alcohol and drugs. Because of their intermittent smoking patterns and the lack of statutory warnings, none felt they were not at risk of any adverse side effects.

CONCLUSIONS

Waterpipe smoking is a growing public health problem; the social environment associated with its use is perceived to be a positive outlet by smokers who do not consider it harmful to their health. These perceptions need to be addressed urgently by anti-smoking policies.

Health-risk behaviors among Iranian university students, 2019: a web-based survey

BACKGROUND

High-risk behaviors are among the most serious threats for the physical and mental health of adolescents and young adults. Our aims in this study were to investigate the subgroups of students based on risky behaviors and to identify the prevalence rate of these subgroups.

METHODS

This cross-sectional web-based survey was conducted from July to August 2019 in Tabriz, Iran. We performed proportional sampling in all nine universities of the city, according to the number of students in each university. Applying an online survey questionnaire, the data were collected from 3649 students and analyzed using Latent Class Analysis.

RESULTS

For total sample, standardized prevalence rates of cigarette smoking, hookah use, alcohol consumption, substance abuse and unsafe sex were 18.5 (Confidence Interval (CI) 95%: 17.3-19.8), 9.1 (CI 95%: 8.2-10.1), 9.2 (CI 95%: 8.3-10.2), 8.3 (CI 95%: 7.4-9.3) and 14.5 (CI 95%: 13.3-15.7), respectively. Three latent classes of risky behaviors were determined among students: a) low risk b) smoking and c) high risk. About 18% of boys and 1.5% of girls were in the high risk class. Cigarette smoking (18.5%, CI 95%: 17.3-19.8) and substance abuse (8.3%, CI 95%: 7.4-9.3) were the most and the least common risky behaviors among the students.

CONCLUSION

In this we-based survey, a considerable number of students, particularly boys (18%), was at high-risk class, stressing the need for preventive interventions for this group of youth. Our findings are beneficial for planning and development of risky-behavior preventive strategies to prevent high-risk behaviors among college students.

Development and Pretesting of Hookah Tobacco Public Education Messages for Young Adults

Young adults’ hookah tobacco use is fueled by misperceptions about risks, appealing flavors, and social use. We developed and pretested public education messages to prevent and reduce hookah tobacco smoking among young adults. We used a two (user status: current hookah user, susceptible never user) by two (risk content: health harms or addiction) by three (message theme: harms/addiction risk alone, harms/addiction risk flavors, or harms/addiction risk social use) design with two messages/condition (n = 12 total messages). Young adults aged 18–30 (N = 713) were randomized to 1 of 12 messages and completed measures assessing message receptivity, attitudes, and negative emotional response. Harms messages were associated with greater receptivity (p < 0.001), positive attitudes (p < 0.001), and negative emotional response (p < 0.001) than addiction messages. Messages with harm or addiction content alone were associated with greater receptivity than social use-themed messages (p = 0.058). Flavor-themed messages did not differ in receptivity from harm or addiction content alone or social use-themed messages. Messages about the health harms of hookah tobacco use resonate more with young adults than addiction risk messages. Social use-themed messages produce the lowest receptivity. These findings can guide population-based approaches to communicate hookah tobacco risks to young adults.

Prevalence and determinants of hookah use among college-going women of Delhi

Background

As governments across the world implement tobacco-control measures, the tobacco industry responds by coming up with new products such as hookah, which are more appealing and affordable for young people-especially women-their primary target group. We assessed the prevalence and determinants of tobacco use among undergraduate women students of the University of Delhi with special emphasis on hookah use.

Methods

Using an anonymous self-administered questionnaire, we conducted a survey among the undergraduate women students of four colleges of the University of Delhi during March 2016. The tool was adapted from standard global surveys and had specific sections on tobacco use and patterns-use of shisha (hookah), smokeless tobacco as well as cessation and exposure to media and awareness about the harmful health effects of tobacco use. Point estimates along with 95% confidence intervals were estimated. Multivariate logistic regression was done to identify the determinants of current tobacco use and hookah use.

Results

Of the 780 respondents (mean [SD] age 19.3 [1.08] years), 22.9% (20.1-26.0) used tobacco in any form, with hookah being the most prevalent form (20.3%). One-third of the respondents believed that hookah smoking was less harmful than cigarette smoking. The major determinants of hookah use were-attending a private school (1.84; 1.11-3.01) or all-women college (2.79; 1.80-4.33); tobacco use by friends (2.47; 1.61-3.77); belief that smoking is a sign of women empowerment (2.09; 1.05-4.1 7) and the belief that hookah smoking is less harmful than cigarette smoking (2.81; 1.92-4.13).

Conclusions

High prevalence of hookah use among young girls and women calls for a comprehensive approach including legislative options as well as increasing awareness about tobacco-cessation programmes among them.

Knowledge and attitude toward waterpipe smoking: scale validation and correlates in the Lebanese adult population

The World Health Organization declared waterpipe smoking as a growing public health concern. Our study aimed to assess waterpipe smoking knowledge and attitude among current waterpipe smokers in comparison with nonsmokers and to evaluate its association with current and cumulative waterpipe smoking. A cross-sectional study was carried between May and December 2018 using a multistage cluster sample across Lebanon. Nonsmokers or exclusive current waterpipe smokers were eligible to participate. A total of 4046 adult individuals participated in the study, 38.3% (n = 1550) being current waterpipe smokers. Current waterpipe smoking was positively associated with female gender [adjusted odds ratio (aOR) 1.79, 95%CI 1.40-2.28] and having a mother who is a regular smoker (aOR 1.47, 95%CI 1.15-1.88) while it was negatively associated with better knowledge about waterpipe smoking harm (aOR 0.95, 95%CI 0.93-0.97) and positive attitude toward waterpipe smoking ban (aOR 0.98, 95%CI 0.96-0.99). Cumulative waterpipe smoking was negatively associated with female gender (β = - 0.012), higher education level (β = - 0.28), and positive attitude toward WPS ban (β = - 0.06). Waterpipe smoking is largely present among the Lebanese population, with waterpipe smokers showing lower knowledge about harm and more intolerant attitude about banning. Health awareness supported by media campaigns and governmental initiatives should be conducted to educate people and change their perceptions regarding waterpipe smoking.

Evaluating the Effects of a Brief Tobacco Intervention in the US Air Force

INTRODUCTION

Military personnel have among the highest rates of tobacco use in the United States. Unfortunately, there are few interventions aimed at reducing tobacco use among this vulnerable population. The current study addresses this need by evaluating the short-term effectiveness of a Brief Tobacco Intervention (BTI), a 40-min group-based intervention designed to reduce contemporary patterns of tobacco use among a sample of US military enlistees during an 11-week period of involuntary tobacco abstinence.

AIMS AND METHODS

Participants were 2999 US Air Force Technical Trainees at Joint Base San Antonio-Lackland Air Force Base in San Antonio, Texas from April 2017 through January 2018. Participants were cluster randomized to three conditions: (1) BTI + Airman's Guide to Remaining Tobacco Free (AG), (2) AG intervention, or (3) standard smoking cessation intervention. The primary analysis was a comparison of the interventions' efficacies in preventing tobacco use during Technical Training, conducted using a generalized estimating equations logistic regression model controlling for covariates. Multiple imputation was used to account for loss to follow-up.

RESULTS

There was not a significant difference by condition in the use of tobacco products at follow-up (p = .454). The BTI + AG condition did produce short-term changes in perceived harm, intentions to use tobacco, knowledge about tobacco products, and normative beliefs.

CONCLUSIONS

These findings suggest that while the intervention was effective in the short term, it was not potent enough over a 12-week period to prevent Airmen from initiating tobacco use. Future studies should examine whether adding a booster session or media campaign enhances the effectiveness of the intervention.

IMPLICATIONS

Despite the fact that most Airmen believe they will remain tobacco free following the ban in Technical Training, a large percentage of these Airmen resume and initiate tobacco use during this high-risk period. As a result, there is a need for interventions targeting the range of tobacco available to military trainees during a teachable moment when they report intentions to remain tobacco free. The current study shows that a BTI has promise in reducing long-term tobacco use, when coupled with additional interventions, such as a booster session or a media campaign.

Agent-based Modeling in Tobacco Regulatory Science: Exploring 'What if' in Waterpipe Smoking

Objectives

Waterpipe tobacco smoking (WTS) is an emerging public health crisis, particularly among youth and young adults. Different from the use of other tobacco products and e-cigarettes, WTS tends to be a social activity occurring among friends or persons associated with social networks. In this paper, we review a potential strategy for WTS-related research.

Methods

As a bottom-up computational model, agent-based modeling (ABM) can simulate the actions and interactions of agents, as well as the dynamic interactions between agents and their environments, to gain an understanding of the functioning of a system. ABM is particularly useful for incorporating the influence of social networks in WTS, and capturing people's space-time activity and the spatial distribution of WTS venues.

Results

Comprehensive knowledge of WTS-related behaviors at the individual level is needed to take advantage of ABM and use it to examine policies such as the interaction between WTS and cigarette smoking and the effect of flavors used in waterpipe tobacco. Longitudinal and WTS-specific surveys and laboratory experiments are particularly helpful to understand WTS basic mechanisms and elicit individual preferences, respectively.

Conclusions

We argue that the uniqueness of WTS makes ABM a promising tool to be used in WTS-related research, as well as understanding use of other tobacco products.

Popular water pipe smoking, medical sciences students' awareness, perceptions, and motivations

Objectives This study was done to investigate popularity, awareness, perceptions, and motivations regarding water pipe smoking (WPS) among medical sciences students in 2017. Methods This cross sectional study was done among 385 medical sciences student in 2017.The systematic random sampling was used to recruit subjects. Multidimensional questionnaire (demographic characteristics, awareness, perceptions, action, and water pipe motivators) was used. t-test, ANOVA, X2, and logistic regression was used to analyze the data by SPSS. Results The mean ages of participants were 22 ± 2.64 and 89% were male. The majority of the study sample was from health school. Most participants reported having smoked before. Family entertainment was found to be the most common motivator for WPS. The second one was to be fun. WPS use was significantly associated with age (odds ratio [OR], 0.17; 95% Confidence Interval [CI], 0.04-0.61); awareness (OR, 1.55; 95% CI, 1.35-1.78); and perception (OR, 0.71; 95% CI, 0.65-0.78). Conclusions Results show that WPS is very popular among Iranian youth. In designing public health programs, policy makers should consider the motivators for inclination to WPS. Intervention should focus on addressing students' perception and awareness regarding WPS.

Waterpipe use among the youth in Ghana: Lessons from the Global Youth Tobacco Survey (GYTS) 2017

INTRODUCTION

The Global Youth Tobacco Survey’s findings have been used to support Ghana’s tobacco control legislation, monitor tobacco use among the youth and also used in meeting various Articles of the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC). These Articles include: Article 8 (Protection for exposure to tobacco smoke); Article 12 (Education, communication, training and public awareness); Article 13 (Tobacco advertising, promotion, and sponsorship); Article 14 (Demand reduction measures concerning tobacco dependence and cessation); and Article 16 (Sales to and by minors). Among the four waves of GYTS in Ghana, the 2017 GYTS was the first to assess waterpipe smoking, through optional questions included in the GYTS questionnaire. We assessed sex, age and regional differentials in waterpipe smoking among the youth in Ghana, and also explored the association between the use of other tobacco products and waterpipe use.

METHODS

The GYTS employs a standardized methodology with self-administered questionnaires, consisting of core, optional, and country specific questions. Fourteen questions, out of the seventy-four (74) questions administered for the entire GYTS, assessed waterpipe tobacco smoking (WTS). Chi-squared test was used to assess sex, age, grade/form and regional differentials in waterpipe use. Furthermore, the association between smoking cigarettes, smokeless tobacco, electronic cigarettes and waterpipe smoking, was explored by employing a chi-squared test with a 5% significance level.

RESULTS

Of a total of 5664 students who participated in the study, 90.9% were aged 13–15 years. The respondents were almost equally distributed among males and females. Overall, 3.1% of the respondents had ever smoked waterpipe. The overall prevalence of current waterpipe use was 1.7%; with 2.1% in girls (95% CI: 0.9–4.7%) and 0.9% in boys (95% CI: 0.5–1.6%), p=0.033. Additionally, more than half (55.0%) of the current waterpipe users smoked three or more sessions per day. Surprisingly, close to half (46.9%) of the current waterpipe users smoked at home.

CONCLUSIONS

Waterpipe use, particularly among the female student population, represents an emerging tobacco epidemic and hence deserves immediate attention from authorities. This study revealed that waterpipe is being used among Junior High students in Ghana. Education on the health implications of waterpipe use should be intensified among the youth, to help minimize its use and to prevent its associated health harms.

Waterpipe Tobacco Smoking and Associated Risk Factors among Bangladeshi University Students: An Exploratory Pilot Study

Over the past two decades, there has been a global rise in the prevalence of waterpipe tobacco smoking. Waterpipe tobacco smoking involves the inhalation of heated tobacco smoke after passing through water, and it has been associated with an identified dependence effect similar to that found with cigarette smoking. Despite the popularity of waterpipe tobacco among youth (and in particular, university students) in many countries, detailed data of its usage are lacking in Bangladesh. Therefore, the present study was conducted to explore waterpipe tobacco smoking behavior and normative beliefs among university students in Bangladesh and to assess the factors associated with waterpipe tobacco use. A quantitative cross-sectional survey was carried out among 340 Bangladeshi university students (64.4% male; mean age 21.6 years). Among participants, 13.5% reported they had ever smoked tobacco from a waterpipe and 9.4% had it in past 30 days. Among past 30-day users, 72% were categorized as having waterpipe smoking dependence (n = 23). No females in the sample had ever smoked using a waterpipe. Maternal occupation, monthly expenditure, and regular smoking status were major predominant factors associated with waterpipe smoking behavior of the students. The study is of existential value given that there are no prior studies ever carried out in Bangladesh previously. Recommendations are provided based on the study’s findings, particularly in relation to what action is needed from universities in Bangladesh.

Development and psychometric properties of the Hookah Smoking Initiation for Women Questionnaire (HIWQ)

The aims of this study were to design the Hookah Smoking Initiation for Women Questionnaire (HIWQ) and determine its psychometric properties. This was a sequential exploratory mixed-methods design consisting of qualitative and quantitative phases. This study was conducted from August 2012 to July 2013 in Tehran. In the qualitative phase, semi-structured interviews were held with 36 Iranian women for developing a preliminary item pool. Consequently, during the quantitative phase, the psychometric properties of the questionnaire were determined with the collaboration of 323 women living in various geographical locations in Tehran, Iran. Content validity of the questionnaire was examined by a panel of experts. The questionnaire's construct validity was assessed using exploratory factor analysis and confirmatory factor analyses. The Cronbach's alpha coefficient was calculated to check the questionnaire's internal consistency reliability. Moreover, its stability was tested using the test-retest method. Exploratory factor analysis indicated that the HIQW could best be explained by a six-factor solution: 'drawing the attention of other people', the need to having fun and being relaxed, 'hookah smoking in the family', 'availability of hookah', 'curiosity' and 'having a positive attitude toward hookah'. It also was found that the construct and content validity, and the reliability of the questionnaire were satisfactory (α = 0.83, ICC = 0.94). The HIQW was valid and reliable. Therefore, healthcare professionals can use it for evaluating the hookah smoking initiation in women. Future studies are required to refine this questionnaire and assess its applicability in different cultures and contexts.

Harm Perceptions of Menthol and Nonmenthol Cigarettes Differ by Brand, Race/Ethnicity, and Gender in US Adult Smokers: Results from PATH Wave 1

INTRODUCTION

Harm perceptions of menthol cigarettes may contribute to their appeal and use. African-Americans, women, and younger smokers disproportionately use menthol cigarettes, and may misperceive harm of menthol cigarettes.

METHODS

Data were from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study. Weighted analyses of current adult smokers (18 and older) were used to estimate the correlates of menthol smoking among all cigarette brands and separately for the top three cigarette brands (Newport, Camel, and Marlboro). Adjusted models examined the main effect of menthol smoking on harm perceptions of one's own brand of cigarette and interactions with race/ethnicity, age, and gender.

RESULTS

Menthol cigarettes were used by nearly 40% of current smokers, although the prevalence of menthol smoking differed across the top three brands (94% Newport, 46% Camel, and 18% Marlboro). Among menthol smokers, 80% perceived their cigarette as equally harmful, 14% perceived their brand as more harmful, and 7% perceived their brand as less harmful. In adjusted models, menthol smokers were more likely than nonmenthol smokers to misperceive their own brand as more harmful than other brands (compared to no difference in harm). Race and gender emerged as moderators of the association between menthol brand preference and harm perceptions.

CONCLUSIONS

In adjusted analyses, menthol smokers were more likely than nonmenthol smokers to perceive their brand as more harmful than other brands, with differences by sub-groups who disproportionately use menthol.

IMPLICATIONS

Menthol cigarettes have been historically marketed with messages conveying lower harm than other cigarettes. Little is known about how contemporary adult menthol smokers perceive the harm of their usual brand, and potential differences by race, gender, and young adult versus older adult age group. After adjusting for other factors, menthol smokers were more likely than nonmenthol smokers to perceive their cigarette brand as more harmful than other brands. Further, the association between menthol smoking and harm perceptions differed by race and gender, but not by age group (young adult vs. older adult). This type of large-scale study identifies critical links between menthol smoking and harm perceptions among vulnerable smokers that will inform regulatory actions designed to decrease smoking-related harm.

Prevalence of Hookah Smoking among University Students in Iran: A Meta-Analysis of Observational Studies

BACKGROUND

The rise in popularity of waterpipe smoking among younger people cause increase its deleterious effects on health in recent years. The aim of this study was to estimate the pooled prevalence of water-pipe smoking in university students in Iran.

METHODS

We performed the literature search from 1946 to January 21, 2019, in several international and national databases such as Medline/PubMed, Web of Science, Scopus, Google Scholar, Magiran, Iranmedex, and IranPsych. To investigate the between-study heterogeneity we used the chi-squared test and I² index. We used a random-effects model to estimate the pooled prevalence of water-pipe smoking. The potential source of heterogeneity was assessed by subgroup analysis and meta-regression.

RESULTS

According to the eligibility criteria, we included 37 relevant studies in our meta-analysis. The pooled prevalence of lifetime water-pipe smoking was 25% (95% CI: 22-29) and in male and female subgroups was 37% (95%CI: 30-45), 17% (95%CI: 15-19) respectively. The pooled prevalence of water-pipe smoking in last year was 21% (95%CI: 16-25) and in last month was 8% (95%CI: 5-11). Results of meta-regression analysis showed that there was not any significant association between suspected variables and the prevalence of water-pipe smoking.

CONCLUSION

The higher prevalence rate of water pipe smoking among university students indicates the emergency need for planning preventive program.

A Call for Effective Interventions to Curb Shisha Tobacco Smoking among University Students in Eastern Province, Saudi Arabia: Findings from a Cross-Sectional Study

BACKGROUND

Although the number of cigarettes smoked has been declining due to major public health initiatives, shisha tobacco smoking is gaining popularity around the world, particularly among youth and university students.

METHODS

A cross-sectional study was conducted among 464 university students in Eastern Province of Saudi Arabia using a structured questionnaire (i) to assess the prevalence of shisha smoking; (ii) to evaluate risk-perception, knowledge and normative belief about shisha smoking, and to compare these among users and non-users of shisha.

RESULTS

The study reported a high prevalence (22.8%) of the current use of shisha among the university students with a narrow gender gap and found that STS is getting more popular than other forms of tobacco. A quarter of participants had low risk perception and 30.2% had low knowledge of shisha smoking harm. Importantly, more than two-fifth of them were current users of shisha. Low risk-perception about shisha and social acceptability were significantly contributed to the high prevalence of shisha smoking among the youth.

CONCLUSION

It is important to provide exposure to education related to shisha hazards and increase the awareness of students and the public about the health effects of shisha smoking.

The effects of hookah/waterpipe smoking on general health and the cardiovascular system

Hookah or waterpipe smoking or use is an emerging trend in the US population, especially among the youth. The misperception of hookah being less harmful than cigarettes and the availability of different but "appealing" flavors are considered among the main reasons for this trend. Hookah users however are exposed to many of the same toxic compounds/by-products as cigarette users, but at dramatically higher levels, which might lead to more severe negative health effects. In fact, hookah users are at risks of infections, cancers, lung disease, and other medical conditions. Moreover, because of the overlapping toxicant/chemical profile to conventional cigarettes, hookah smoke effects on the cardiovascular system are thought to be comparable to those of conventional cigarettes. A major source of tobacco addiction is nicotine, whose levels in hookah are extremely variable as they depend on the type of tobacco used. Taken together, in this review of literature, we will provide insights on the negative health effects of hookah in general, with a focus on what is known regarding its impact on the cardiovascular system.

Characteristics of Hookah Tobacco Smoking Sessions and Correlates of Use Frequency Among US Adults: Findings From Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study

Introduction

Hookah tobacco smoking has increased in the United States. However, information on hookah use frequency and other characteristics of hookah use is limited.

Methods

Investigators analyzed data from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative, longitudinal cohort study of US youth and adults. Our analysis draws on baseline data from adult (ages ≥18 years) ever (N = 10 624) and past year (n = 3947) hookah users. Bivariate and regression analyses were conducted to identify associations between demographics, use characteristics, and hookah use frequency.

Results

Overall, 16.4% of adults reported ever smoking tobacco from a hookah. Of those, 31.9% reported smoking hookah within the past year. Among 3947 past-year hookah tobacco smokers, 10.7% were daily/weekly users, 13.7% were monthly users, 42.1% smoked every couple of months, and 33.5% smoked about once a year. Among daily/weekly hookah users, 66% were young adults (ages 18-24 years). When comparing daily/weekly hookah users to those who smoked every couple of months, more frequent hookah use was associated with younger age, male gender, a greater number of times the hookah is refilled during a session, fewer people sharing, and hookah ownership.

Conclusion

Although there were few demographic differences between daily/weekly users and less frequent hookah tobacco smokers, some notable differences in use behaviors exist among use frequency groups. Unlike other tobacco products, hookah is often smoked communally, over an extended time period. A detailed understanding of hookah user characteristics and experiences could inform hookah-specific measures, messaging, and regulations.

Implications

To our knowledge, this is one of the first studies to characterize hookah use frequency, session length, and other hookah use experiences using a nationally representative sample of US adult hookah smokers. Understanding characteristics of hookah tobacco smokers, their use experiences, and patterns of hookah use frequency would be useful in assessing risks for hookah tobacco dependence at the population level. Additionally, identifying variation in use behaviors of hookah tobacco smokers could be used to inform the development of strategies to reduce and prevent hookah tobacco use, such as tobacco regulations or public education efforts, particularly among young adults.

Waterpipe or Hookah-Related Poisoning Events Among U.S. Adolescents and Young Adults

PURPOSE

Waterpipe or hookah use is associated with carbon monoxide poisoning and effects such as nausea and vomiting. We examined the public health burden of poisoning events involving hookah tobacco in the U.S., especially among adolescents and young adults.

METHODS

We analyzed events involving hookah tobacco that were reported to U.S. poison control centers between 2001 and 2017 by age and over time as well as by medical outcome, health care level, and clinical effects.

RESULTS

A total of 276 relevant poisoning events involving hookah were reported. Among the 248 individuals with a specific age reported, 35 (14.1%) were aged between 10 and 17 years and 136 (54.8%) were aged between 18 and 24 years. Common clinical effects included dizziness/vertigo, nausea, headache, and vomiting.

CONCLUSIONS

Hookah tobacco use is associated with poisoning events consistent with exposure to high levels of carbon monoxide.

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.

Prevalence, knowledge and practices of shisha smoking among youth in Kampala City, Uganda

INTRODUCTION

globally tobacco use kills more than seven million people annually, a figure expected to rise to 8 million deaths every year by 2030. Though perceived as safe, shisha smoking is reported to have the same or worse health effects as cigarette smoking yet, this practice has gained popularity especially among youths globally. We assessed shisha smoking and factors associated with shisha smoking to support public health interventions.

METHODS

a cross-sectional study was conducted among 663 systematically selected youths aged between 18-30 years attending bars in two divisions of Kampala city Uganda. Data was analyzed using Stata version 12 and logistic regression model run to establish factors independently associated with shisha smoking.

RESULTS

we found that 458 (86.4%) youths had low knowledge of the health effects of shisha and 193 (36.4%) smoked shisha. Majority of the respondents, 184 (97.4%) smoked flavoured and sweetened tobacco, 69 (36.5%) smoked on a weekly basis, 163 (86.2%) smoked in the company of friends, 162 (85.7%) shared shisha pipes. Factors associated with shisha smoking include smoking cigarettes adjusted odds ratio [aOR]: 5.91, 95% Confidence Interval (CI): 3.86-9.05); positive attitude (aOR: 3.89, 95% CI: 2.50-6.05); urban residence (aOR: 3.98, 95% CI: 1.99-8.00) and older age [25-30 years] (aOR: 2.13, 95% CI: 1.37-3.22).

CONCLUSION

the prevalence of shisha smoking is high with three in ten youths smoking shisha yet their knowledge about the health effects associated with shisha smoking was low. Shisha smoking ban should be implemented in all bars in Kampala as stated by the newly enacted tobacco law.

Sexual risk behavior and substance use among young, diverse women seeking care at a reproductive health clinic

BACKGROUND

To describe sexual risk behavior, alcohol (and other substance) use, and perceived health promotion needs among young adult women seeking care from an urban reproductive health care clinic in the Northeastern United States, and to examine if these needs differ by race and ethnicity.

METHODS

Women 18-29 years old presenting for a routine medical visit were invited to participate. Of 486 eligible women, 466 (96%) agreed to participate and completed a brief survey on a tablet computer. Most of the sample (53%) identified as non-Hispanic White. One-quarter (25%) identified as Hispanic/Latina. A smaller proportion of women identified as African American (19%).

RESULTS

One-third (31%) of women reported a history of sexually transmitted infection (STI), and women reported infrequent condom use with recent sexual partners. Regarding behavioral health needs, nearly three-quarters of women (72%) reported regular alcohol use, approximately one-third had used marijuana (37%) or tobacco (33%) in the last month, and 19% reported clinically significant depressive symptoms in the last two weeks. Women reported moderate-to-strong interest in receiving information about relationships and sexual health; however, the majority were not interested in information about their substance use. Hispanic and African-American women were more likely to report STI history despite reporting fewer sexual partners than non-Hispanic White women. Minority women also reported significantly less alcohol and cigarette use, but more water pipe tobacco use, and reported significantly greater interest in interventions to promote sexual health. Hispanic women also evidenced significantly elevated rates of depressive symptoms, with 26% of Hispanic women reporting a clinically significant level of depressive symptoms.

CONCLUSIONS

Reproductive health centers are opportune settings to address a broad range of healthcare needs, including sexual health, substance use, and mental health. These centers engage a diverse group of women, which is important given observed disparities in health outcomes based on race/ethnicity. Young women, particularly racial and ethnic minority women, report the most interest in services addressing sexual and relationship health.

Curiosity About and Susceptibility Toward Hookah Smoking Among Middle and High School Students

Introduction

Hookah smoking has increased among young people. Curiosity and susceptibility may be associated with experimentation or established use. Because tobacco use behaviors are established primarily during adolescence, our objective was to examine factors that may increase the risk of future tobacco product use among youth.

Methods

We analyzed data from the 2016 National Youth Tobacco Survey, a nationally representative survey of US students. Analyses were restricted to youth who had never smoked a hookah and stratified by their ever having used other tobacco products. The prevalence of hookah curiosity and susceptibility was assessed by sociodemographic characteristics, perceptions of harmfulness and addictiveness of hookahs, and peer use of hookahs. Associations between covariates and curiosity and susceptibility were assessed by using multivariable-adjusted regression.

Results

Overall, 29.1% of students reported any hookah curiosity or susceptibility. Curiosity was reported by 14.6% of those who never used tobacco products and by 45.9% of those who ever used tobacco products. Hookah susceptibility was reported by 15.6% of never-users and 52.5% of ever-users. Regardless of ever having used other tobacco products, odds of curiosity and susceptibility were higher among students with perceptions of reduced hookah harmfulness and addictiveness and among those who perceived high levels of hookah use among peers.

Conclusion

Nearly 3 in 10 youth who never smoked a hookah (6.9 million) reported hookah curiosity or susceptibility, and prevalence was highest among those who had ever used other tobacco products. These findings reinforce the importance of educating youth about the dangers of all tobacco products and dispel misperceptions about the harmfulness and addictiveness of hookah smoking. Continued surveillance of youth curiosity, susceptibility, and use of hookahs can inform public health policy and practice.

Adolescent Beliefs About Hookah and Hookah Tobacco Use and Implications for Preventing Use

Introduction

Hookah tobacco use is popular among youths and there is evidence that perceived risks and normative beliefs are associated with hookah use. The aim of this study was to further examine associations between perceived risks of hookah use, normative beliefs, and lifetime hookah use among youths.

Methods

Participants were adolescents aged 12 to 17 years (n = 257, mean [standard deviation] age, 14.9 [1.6] years, 40% nonwhite, 66% female) attending well-visit checkups at an urban pediatric clinic. Participants completed a survey of measures of cigarette smoking, risk factors for smoking, hookah use, perceived risks, and normative beliefs. Analyses examined associations among lifetime hookah use, beliefs about hookah use, and other smoking risk factors.

Results

Overall, 15% of the sample had ever tried hookah smoking and 60% had ever tried cigarette smoking or were susceptible to cigarette smoking. Of those who had tried hookah smoking, 84% had also tried cigarettes or were susceptible to trying cigarettes (P < .001). One-third (33%) indicated that hookah smoking was less harmful than cigarettes, 38% indicated hookah smoking is less addictive than cigarettes, and 48% perceived that hookah smoking is somewhat or very socially acceptable among friends. In multivariable analyses adjusting for demographic and cigarette smoking–related factors, perceiving hookah use to be somewhat or very socially acceptable was associated with a significantly higher odds of ever having tried hookah smoking.

Conclusion

The study findings indicate that stronger perceived social acceptability of hookah use is associated with a higher likelihood of trying hookah smoking among youths. These normative beliefs may be important targets of interventions aimed at preventing hookah use among youths.

Chemical Characterization of Nanoparticles and Volatiles Present in Mainstream Hookah Smoke

Waterpipe smoking is becoming more popular worldwide and there is a pressing need to better characterize the exposure of smokers to chemical compounds present in the mainstream smoke. We report real-time measurements of mainstream smoke for carbon monoxide, volatile organic compounds and nanoparticle size distribution and chemical composition using a custom dilution flow tube. A conventional tobacco mixture, a dark leaf unwashed tobacco and a nicotine-free herbal tobacco were studied. Results show that carbon monoxide is present in the mainstream smoke and originates primarily from the charcoal used to heat the tobacco. Online measurements of volatile organic compounds in mainstream smoke showed an overwhelming contribution from glycerol. Gas phase analysis also showed that very little filtration of the gas phase products is provided by the percolation of mainstream smoke through water. Waterpipe smoking generated high concentrations of 4-100 nm nanoparticles, which were mainly composed of sugar derivatives and especially abundant in the first 10 min of the smoking session. These measured emissions of volatiles and particles are compared with those from a reference cigarette (3R4F) and represent the equivalent of the emission of one or more entire cigarettes for a single puff of hookah smoke. Considerations related to the health impacts of waterpipe smoking are discussed.

The association between perceived e-cigarette and nicotine addictiveness, information-seeking, and e-cigarette trial among U.S. adults

Perceptions of harm and addictiveness are associated with smoking combusted cigarettes, but these factors have not been fully explored for e-cigarettes. Specifically, little is known about the perceived harm and addictiveness of e-cigarettes, or whether information-seeking about e-cigarettes is related to trying e-cigarettes. We aimed to determine the relationship between (1) perceived e-cigarette harm and addictiveness and trying e-cigarettes; (2) nicotine perceptions and trying e-cigarettes; and (3) e-cigarette information-seeking, Internet use, and trying e-cigarettes. We used data from the nationally representative 2015 Health Information National Trends Survey-FDA (HINTS-FDA 2015). Weighted multivariable logistic regression models assessed independent associations between perceived e-cigarette harm, perceived e-cigarette addictiveness, nicotine perceptions, e-cigarette information-seeking, personal Internet use, and trying e-cigarettes, among 3195 adults. Compared to people who believed e-cigarettes were equally or more addictive than combusted cigarettes, those who believed e-cigarettes were less addictive had 2.49 times the odds of trying e-cigarettes (95% confidence interval [CI]: 1.30, 4.74). Perceived e-cigarette harm and nicotine perceptions were not associated with trying e-cigarettes. The positive association between e-cigarette addictiveness and trying e-cigarettes coupled with the lack of an association between nicotine perceptions and trying e-cigarettes suggests people do not fully understand that e-cigarettes contain nicotine and therefore could be addictive. People most frequently reported searching for information about potential health effects of e-cigarettes (37.9%), indicating that people are interested in learning about the potential impact of e-cigarette use on their health. People who searched for information about e-cigarettes had 10.23 higher odds of trying e-cigarettes (CI: 5.41, 19.33).

Waterpipe Tobacco Smoking: A Mini-review

The waterpipe tobacco smoking is an ancient form of smoking that is present in the society since centuries. The majority of consumers of this exotic activity are still unaware of the serious consequences that this type of smoking has on the health of the smoker. The paucity of data related to the prevalence and extent of this habit in the society is still not available. In this present short review, the authors try to highlight this serious health issue and suggest preventive measures.

Reasons for Young Adult Waterpipe Use in Wave 1 (2013-2014) of the Population Assessment of Tobacco and Health Study

INTRODUCTION

Waterpipe use is common among U.S. young adults (aged 18-24 years), with estimates considerably higher than other age groups. Although studies have examined attitudes and beliefs associated with waterpipe use, no study has examined reasons for use in a nationally representative sample.

METHODS

Using latent class analyses, this study examined subgroups based on self-reported reasons for use of past 30-day young adult (aged 18-24 years) waterpipe users (n=1,198) from Wave 1 (2013-2014) of the Population Assessment of Tobacco and Health Study. Data analyses were conducted in 2017. Covariates included sociodemographic characteristics, substance use, and internalizing and externalizing problems.

RESULTS

A three-class model was identified: Class 1 (socializing and flavors, 57%), Class 2 (many reasons [flavors, socializing, less harmful than cigarettes, and affordability], 20%), and Class 3 (socializing, 23%). Class 3 was considered the referent group. Compared with non-Hispanic whites, non-Hispanic blacks were less likely to belong to Class 1, whereas Hispanics were more likely to belong to Class 2. Compared with less than high school education, greater than high school education was associated with membership in Class 1; however, high school graduation was associated with membership in Class 2. Past-year alcohol users compared with non-users were less likely to belong to Class 2. Past 30-day poly-tobacco users compared with non-users were more likely to belong to Class 2.

CONCLUSIONS

This study revealed distinct classes of waterpipe users based on self-reported reasons for use. Findings inform targeted policies for waterpipe tobacco control as part of public health efforts to mitigate harms associated with tobacco use.

Stress, stressors, and substance use: Differential risk for hookah use among African American college students

Using differential, multivariable risk models, we assessed the contribution of substance use and stress/traumatic events to hookah use among African American college students (n = 1,402) using data from the Fall 2012 American College Health Association-National College Health Assessment (ACHA-NCHA) II. Lifetime hookah use was 24.8%, with 34.2% of lifetime users having done so in the past 30 days. Compared to nonusers, hookah users had significantly higher use rates of alcohol, marijuana, other tobacco, and other drugs. Furthermore, hookah use was more likely among those with cumulative stress, yet less likely among older students. An implication is that prevention messages may need to be tailored for African American college students and particularly target younger students, substance users, and those with cumulative stress. These findings also inform policy discussions regarding hookah use on college campuses.

Reasons for use, potential use, or discontinued use of hookah among US young adult college students

INTRODUCTION

Given the increase in hookah use among young adults, characteristics of hookah use/users, as well as reasons for its use or discontinuation among young adults, are critical to understand.

METHODS

Data from a study of 18–25 year olds from seven Georgia colleges/universities (n=2865) were analyzed to examined: 1) differences in socio-demographics and other substance use among current (past 4 months), never, and former hookah users; 2) use characteristics among current users (e.g. device types/flavors used, quit intentions); and 3) reasons for use, potential use, and discontinued use among current, never, and former users.

RESULTS

Of the students, 56.3% were never users, 12.4% were current, and 31.3% former users. Correlates of being a current (vs never) user included being ‘other race’ (vs White), attending a historically black college/university (HBCU vs technical college), and use of other substances. Correlates of being a former (vs never) hookah user included being older (vs younger), being ‘other race’ (vs White), attending an HBCU (vs technical college), and use of other tobacco products, marijuana, or alcohol. Among current users, 73.7% reported no intention to quit; 26.2% attempted to quit in the past year. Two factors were identified regarding reasons for current use (flavors, social reasons): one factor regarding potential use among never users (related to flavors and social factors), and three factors regarding discontinued use (inconvenience, anti-tobacco attitude, social reasons).

CONCLUSIONS

Findings indicate the risk factors for hookah use and the importance of particular factors (e.g. flavors, social influences) relevant to regulation/policy.

Prevalence and factors associated with use of hookah tobacco among young adults in the U.S

INTRODUCTION

Among young adults, use of hookah tobacco (HT) is an emerging health-risk behavior. The goals were to demonstrate that (1) the prevalence of ever-use and current use of HT increased among U.S. young adults (18-30 years old) in the period from 2010 to 2015 and (2) the patterns of HT use differed across diverse demographic subpopulations of young adults.

METHODS

We merged and analyzed data from the 2010-2011 and 2014-2015 Tobacco Use Supplement to the Current Population Survey. The sample (n = 55,352) was representative of the young adult population in the U.S. Two binary measures were the ever and current use of HT. The significance level was 5%.

RESULTS

The rate of current use of HT increased from 1% in 2010-11 to 2% in 2014-15 (CI = 0.6%:1.1%). The rate of ever-use increased from 7% to 12% (CI = 4.2%:5.6%). The over-time increase was not uniform: the increase was most rapid among 26-30 year-old adults, non-Hispanic Black and African American adults, and in Northeastern and Midwestern U.S. regions. HT ever-use, overall, was associated (all p's < 0.001) with many sociodemographic factors and current tobacco-use behaviors. The rate of HT ever-use was 16% for daily and 23% for occasional cigarette smokers, 23% for users of smokeless tobacco products, 37% for cigar smokers, and 55% for smokers of regular pipe (filled with tobacco).

DISCUSSION/CONCLUSION

HT use is becoming increasingly more popular among young adults in the U.S. Methods should target not only cessation of cigarette smoking but use of all tobacco products.

Differences in puff topography, toxicant exposure, and subjective response between waterpipe tobacco smoking men and women

Waterpipe tobacco smoking (WTS) exposes users to toxicants in much greater amounts than a cigarette. Little is known about how gender affects WTS toxicant exposure and subjective response. Data from three WTS clinical laboratory studies were combined for analysis. Participants (N = 99; 38 women) completed a 45-min WTS session where they smoked a waterpipe ad libitum. Puff topography was measured throughout, and plasma nicotine concentration, expired air carbon monoxide (CO), and subjective responses were measured pre- and post-WTS. There was a gender effect for total puff volume with men inhaling a greater smoke volume, on average (M = 59.9 L, SD = 40.7), compared with women (M = 38.8 L, SD = 27.8; p < .01). Men had greater post-WTS mean plasma nicotine concentrations (M = 10.0 ng/ml, SD = 7.1) compared with women (M = 6.9 ng/ml, SD = 5.2; p < .05). Post-WTS expired air CO was not associated with gender (men M = 27.6 ppm, SD = 18.9; women M = 22.7 ppm, SD = 17.0, ns). Relative to men, women had higher post-WTS scores for subjective measures of "nauseous," "dizzy," "nervous," "headache," and "heart pounding." Men and women are exposed to toxicants during WTS, and men may achieve higher nicotine exposure than women, likely resulting from differences in smoke inhaled. However, similar post-WTS expired air CO between men and women and higher ratings of negative subjective responses among women may indicate that factors beyond puff topography may impact toxicant exposure and subjective response to WTS.

Social Norms and Self-Efficacy to Quit Waterpipe Use: Findings from a Tobacco Study among Male Smokers in Rural Viet Nam

Introduction: Waterpipe use is a significant health concern in low- and middle-income countries like Viet Nam, yet there is a lack of research on factors that may influence use and self-efficacy to quit among adults.

Aims: This study examined the relationship between social norms related to waterpipe use and self-efficacy to quit among male waterpipe smokers in Viet Nam.

Methods: A cross-sectional survey was conducted with 214 adult male waterpipe smokers enrolled in a large cluster–randomised controlled trial conducted in a rural province in Viet Nam. Associations between social norms related to waterpipe smoking and the participants’ confidence to quit waterpipes were assessed using hierarchical regression models to account for differences among study sites and other covariates.

Results: Self-efficacy to quit smoking was positively associated with immediate family members’ not minding participants smoking and with extended family's encouragement to quit smoking.

Conclusions: The findings suggest the need for a more comprehensive understanding of the functions and characteristics of the social context of waterpipe smoking, including the social networks of waterpipe smokers, to inform effective cessation interventions for waterpipe smokers.

Urban college student self-report of hookah use with health care providers

OBJECTIVE

This study's purpose was to describe urban college students' communication about hookah with health care providers.

PARTICIPANTS

Participants included a random sample of undergraduate urban college students and health care providers.

METHODS

Students surveyed determined the epidemiology of hookah use in this population, how many health care providers asked about hookah, and how many students admitted hookah use to a physician.

RESULTS

Of 375 students surveyed, 78 (20.8%) had never tried it, 284 (75.7%) had smoked hookah at least once, and 64 students (22.6%) were classified as frequent hookah smokers. Only 15 (4.7%) reported a health care provider asking about hookah during visits, whereas 36 (12.7%) admitted their hookah use to a health care provider.

CONCLUSION

Hookah use was found to be highly prevalent among students in one urban university. This study supports the hypothesis that few health care providers broach the topic with patients. Additional research on health consequences of hookah use, education, and improved screening is warranted.

Comparison of toxicant load from waterpipe and cigarette tobacco smoking among young adults in the USA

OBJECTIVES

To form population-level comparisons of total smoke volume, tar, carbon monoxide and nicotine consumed from waterpipe tobacco smoking (WTS) and cigarette smoking using data from a nationally representative sample of smokers and non-smokers aged 18-30 years.

METHODS

In March and April 2013, we surveyed a nationally representative sample of 3254 US young adults to assess the frequency and volume of WTS and cigarette smoking. We used Monte Carlo analyses with 5000 repetitions to estimate the proportions of toxicants originating from WTS and cigarette smoking. Analyses incorporated survey weights and used recent meta-analytic data to estimate toxicant exposures associated with WTS and cigarette smoking.

RESULTS

Compared with the additive estimates of WTS and cigarette smoking combined, 54.9% (95% CI 37.5% to 72.2%) of smoke volume was attributed to WTS. The proportions of tar attributable to WTS was 20.8% (95% CI 6.5% to 35.2%), carbon monoxide 10.3% (95% CI 3.3% to 17.3%) and nicotine 2.4% (95% CI 0.9% to 3.8%).

CONCLUSIONS

WTS accounted for over half of the tobacco smoke volume consumed among young US adult waterpipe and cigarette smokers. Toxicant exposures to tar, carbon monoxide and nicotine were lower, but still substantial, for WTS alone compared with WTS and cigarette smoking. Public health and policy interventions to reduce harm from tobacco smoking in young US adults should explicitly address WTS toxicant exposures.
