Hookahs have been rising in popularity in the United States (U.S.) especially among the youth yet not much research has been carried out to understand the various predictors of hookah use among youth. We have thus conducted a cross-sectional study with a mixed-methods triangulation design to identify the hookah use determinants at different levels of the Social Ecological Model among youth. Participants between the ages of 18-24 years were sampled purposively, between April to November 2023, following a snowballing technique from various communities in Virginia and California, United States. Data were collected via a survey, one-on-one interviews, and focus groups. The study had a total sample size of 20. We found that participants smoked for a median of 5 times in the past 30 days. The main determinants of hookah smoking included the limited knowledge of health effects and addiction, positive attitude, family and peer influence, use as a means to socially connect with others, culture, social acceptability, lack of education at school and work place, access to hookah bars and smoke shops, and lack of strict enforcement of laws to ban smoking of youth. Educational interventions should be implemented by public health authorities to target the youth, their social and communities to provide education on hookah harm and addictiveness and to restrict access to- and the production, distribution, marketing and sales of hookahs., (© 2024.

Introduction: The research regarding the effect of hookah smoking on health is still deficient, even though it has been proven to jeopardize human health by raising the hazard of different types of cancers, infections, and cardiovascular disease. We aimed to study the effect of dual tobacco smoking (hookah and cigarettes) on semen parameters of infertile men., Methods: In this cross-sectional study, we studied the effect of different types of smoking patterns on human semen parameters among men who visited IVF laboratories to do a seminal fluid analysis (SFA). A total number of 761 participants were included, divided into the following: 108 dual smokers, 219 hookah smokers, 222 cigarette smokers, and 212 non-smokers. To analyze the effect of dual smoking on normal morphology, an interaction term between the cigarette index and hookah index was used., Results: Multivariable regression analysis after adjustment for age, BMI, education level, children, chronic diseases, varicocele, testicular surgery history, infertility duration, and cause revealed no significant difference in the sperm concentration and the percentage of progressive motility between non-smokers, cigarette smokers, or hookah smokers. However, there was a significant difference in the log of normal morphology percentage between the three groups. Cigarette and hookah smoking were significantly associated with having lower percentages of normal morphology. There was a significant difference in the log-normal morphology %, where light and heavy dual smokers had the least exponential beta of log-normal morphology %, 0.43 (95% CI: 0.33-0.55) and 0.36 (95% CI: 0.24-0.53), respectively., Conclusions: Dual tobacco smoking can adversely affect sperm morphology., Competing Interests: The authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest and none was reported., (© 2024 Albeitawi S. et al.)

Background: Hookah smoking has pointedly increased worldwide and could have different harmful health effects. However, long term hookah smoking effects on chronic diseases has not been well studied. This study was aimed to investigate the relationship between hookah smoking with metabolic syndrome and diabetes., Methods: In this prospective study, the baseline data from 3695 participant (35-70 years old) of Bandar-e-Kong cohort study in Hormozgan province, Iran were used. In this study, data were collected through the questionnaires designed in the Kong cohort study and 25 mm of blood sample. All analyses were performed using SPSS version 27.0 and the ggplot2 package in RStudio version 2023.06.1 + 524. p  < 0.05 was considered a significant difference., Results: The prevalence of hookah smoking was 17.3% in total. Also, the prevalence of metabolic syndrome, diabetes, hypertension, and dyslipidemia were 35.6, 15.2, 31.2, and 78.0%, respectively. Our results showed that there were statistically significant relationship between hookah smoking and metabolic syndrome, hypertension and diabetes ( p  < 0.05). In the case of dyslipidemia, hookah smoking was also associated with increase in dyslipidemia ( p  < 0.05)., Conclusions: More evidence is needed to understand the mechanism of hookah smoking and these health effects. As well as, health education and increasing public awareness about the health effects of hookah smoking and implementation of smoking prohibition policies are highly recommended., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.

Introduction: The purpose of this survey was to assess the prevalence of hookah smokers among children and adolescents aged 12-16 years in Belarus., Methods: This survey involved 3485 people, including 1737 girls and 1726 boys, and included 6 questions from the main questionnaire of the GYTS aimed at hookah consumption. The statistical processing was performed using the SUDAAN software package; a 95% confidence interval was calculated to calculate weighted prevalence estimates and standard errors., Results: According to the GYTS carried out in the Republic of Belarus in 2021, hookah smoking is becoming increasingly popular. The number of adolescents who have ever smoked a hookah is 9.3%. The prevalence of regular hookah smokers is quite low (0.9%). But there are justified fears that teens who have never smoked cigarettes but have tried hookah are more likely to start smoking cigarettes and become regular cigarette smokers two years later.The frequency of hookah use naturally increases with age. The number of adolescents who have ever smoked a hookah among those aged 14, 15 and 16 years (10.7%, 11.7% and 18.2%, respectively), was higher than among students aged 12 years (5.5%) or 13 years (5.6%) (p<0.001); hookah smoking was higher among students in the 9th and 10th grades (13.0% and 14.2%, respectively), then among students in the 7th grade (5.1%) (p<0.001)., Conclusions: This national survey provides the first data of prevalence of hookah smoking among children and adolescents in Belarus and allows us to conclude that the growing popularity of waterpipe tobacco smoking dictates the need for timely recommendations on waterpipe smoking policy., Competing Interests: The authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest and none was reported., (© 2023 Pronina T. and Sychik S.)

Background The overall frequency and incidence of different cancers across the globe, including lung cancer, are marked by ethnic and geographical variations. Lung cancer is the most commonly diagnosed cancer worldwide that inflicts most of the cancer deaths. Non-small cell lung cancer (NSCLC) constitutes most lung cancer cases. The aim of this study was to find the frequency and clinicopathological characteristics of NSCLC in high incidence zone of Kashmir, an ethnically and geographically distinct area in Northern India. Material and methods The study was conducted to evaluate the clinicopathological profile of NSCLC at a tertiary care cancer center, Sher-I-Kashmir Institute of Medical Sciences (SKIMS). The patients and case records were analyzed for clinical presentation and demographic features, smoking status, radiological features, histopathological type, and stage of their disease at presentation. Results The study included 1557 NSCLC patients registered over a period of seven years, i.e., 2008-2014. Most of the patients belonged to rural areas (70%). The median age of the whole cohort was 58.0 years (ranges 22-95 years), and the male-to-female ratio was 3.7:1 (male = 1231 and female = 326). Smokers comprised 77.39% of cases, and Hookah was the most common form of smoking (65.06%). The ratio of squamous cell carcinoma and adenocarcinoma was 3.7:1 (67.5% vs. 24.9%). Stage III and IV disease accounted for 93% of cases (30.6% and 62.7%, respectively). Squamous cell carcinoma histopathology was dominant in smokers (74.3%) compared to adenocarcinoma (19%), while squamous cell carcinoma and adenocarcinoma histopathology ran parallel in nonsmokers (45.1% and 44%, respectively). Most of the patients had an Eastern Cooperative Oncology Group (ECOG) performance status between 1 and 2 (79%).  Conclusion We conclude Kashmir region is a very high-risk area for lung cancer, with NSCLC showing a high incidence. Most of our patients present in advanced stages, and the frequency of adenocarcinoma is showing an increasing trend over the years from 2008-2014., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Mir et al.)

Background: Smoking is a public health problem that affects the adolescent population's health. This study aimed to investigate the relationship between extroversion (compared with introversion) and transition in cigarette and hookah smoking stages in high-school students to use the results in smoking prevention programs., Methods: A sample of 2312 students aged 15-16 years in Tabriz were included in the study. Demographic characteristics, cigarette, hookah smoking status, and Eysenck's extroversion questionnaires were completed by all students in the selected schools. Eight months later, cigarette and hookah smoking status were assessed again to determine transition in smoking stages. The marginal homogeneity (MH) test was used to compare the smoking status at the beginning and 8 months later. The generalized estimating equation (GEE) method with the ordinal link was applied to estimate the effect of extroversion on transition in smoking stages., Results: The mean (standard deviation) age of the students participating in the study was 15.5 (0.5) years. MH test results showed that, in general, transmission in the stages of both cigarette and hookah smoking in 8 months was significant in students ( P -value < 0.0001). Extrovert personality had a significant positive effect on the transition from lower stages to higher cigarette and hookah smoking stages according to the GEE with ordinal link ( P = 0.01). In cigarette and hookah smoking, extrovert persons transited to higher stages 1.64 and 1.55 times more than introvert persons., Conclusions: Being an extrovert person had a significant effect on the transitioning to higher stages of smoking cigarettes and hookah. In designing cognitive programs to prevent people from smoking or encourage them to quit smoking, considering this dimension of personality trait can be useful in the efficacy of the program., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 International Journal of Preventive Medicine.)

Hookah smoking is one of the major indoor sources of benzene, toluene, ethylbenzene, and xylenes (BTEX). This study aimed to investigate the potential exposure to BTEX among primary school children, particularly those exposed to hookah smoke. This cross-sectional study was conducted in Khesht, one of the southwestern cities in Iran, in mid-June 2020. Totally, 50 primary school children exposed to hookah smoke were chosen as the case group and 50 primary school children were selected as the control group. Urinary un-metabolized BTEX was measured by a headspace gas chromatography mass spectrometry (GC-MS). Additionally, a detailed questionnaire was used to gather data and information from the students' parents. The mean levels of urinary benzene, toluene, ethylbenzene, m,p-xylene, and o-xylene were 1.44, 5.87, 2.49, 6.93, and 7.17 μg/L, respectively in the exposed children. Urinary BTEX was 3.93-folds higher in the case group than in the controls (p<0.05). Household cleaning products, the floor on which the house was located, children's sleeping place, and playing outdoors were found to be important factors in predicting urinary BTEX levels. Overall, it was found necessary to avoid indoor smoking to prevent the emission of BTEX compounds via exhaled mainstream smoke and to protect vulnerable non-smokers, especially children, from exposure to second-hand and third-hand smoke., (© 2022.

Background: This study assesses the long-term effectiveness of a lifestyle intervention on cigarette, passive, and hookah smoking in adolescent boys and girls., Methods: One thousand one hundred and fifty-nine adolescent participants of Tehran Lipid and Glucose Study (TLGS) (2001-2004) were followed for 12 years. Participants in the intervention area received lifestyle interventions in family, schools, and community settings, with the largest part implemented in schools. After excluding those with missing baseline parental data (n = 66), complete parental data of 1093 adolescents was used for cluster analysis. Families were classified as low- and high-risk. Two hundred and ninety-six individuals who did not complete intervention/follow-ups were excluded, GEE was performed on 797 adolescents (369 boys, 192 intervention) to assess the intervention effect on tobacco-related habits., Results: Adolescents' mean baseline age was 15.21 ± 1.95. Those living in high-risk families were more at risk of cigarette, passive, and hookah smoking. Intervention decreased odds of cigarette and passive smoking by 38% and 57%, respectively. Intervention did not reduce hookah smoking in adolescents. After sex-specific analysis, the intervention reduced current cigarette smoking by 40% only in boys and passive smoking in both sexes., Conclusions: Targeting lifestyle behaviors in school-aged adolescents and their families reduces cigarette smoking in boys and protects both sexes from secondhand smoke., (© 2022, American School Health Association.)

Background: The present study aimed to evaluate the results of a theory-based and systematic intervention on Hookah Tobacco Smoking (HTS) cessation in women local to Bandar Abbas, Iran., Methods: In the present quasi-experimental research, we used an intervention mapping approach to develop, implement, and evaluate an education and training course as our intervention. Applying the results of a systematic review and two prior local qualitative studies, we identified six HTS determinants and set goals for the intervention. We selected 212 eligible women through systematic stratified random sampling and enrolled them in control and intervention groups. The course was presented to the intervention group in 17 sessions for four months. The educational material was developed to address the goals of the intervention, improve HTS determinants, and change the HTS behavior. We used a questionnaire to collect data on participants' characteristics, HTS behavior, and detailed determinants of HTS in the control and intervention groups at the beginning of the study, at the end of the intervention, and at three- and six- months follow-up. All work done in the study was guided by ethical considerations., Results: The results showed no significant difference between women enrolled in control and intervention groups regarding participants' characteristics and HTS behavior. At baseline, there were no differences between groups for six determinants of HTS (knowledge, attitude, social norms, self-efficacy, habit, and intention). At the end of the intervention and at three and six months follow-up, the women in the intervention group had significantly better results in all six domains, compared with those in the control group. The rate of HTS abstinence at the end of the intervention and at the three- and six-month follow-ups was 61.3%, 48.5%, and 45.5% for the intervention and 16%, 14.4%, and 10% for the control groups, respectively., Conclusions: HTS is a complicated behavior, and its cessation is hard. However, Intervention Mapping (IM) can be a powerful integrative, purposeful, theory-based, and participation-based method to reduce or cease HTS. This method should be tested in other settings., Trial Registration: IRCT20190126042494N1, Registered 3.3.2019. https://en.irct.ir/trial/37129., (© 2022. The Author(s).)

Introduction: The epidemic tobacco use is a public health concern worldwide. This study aimed to evaluate the prevalence of tobacco use and its socioeconomic determinants in the city of Shiraz, Iran., Methods: In total, 5873 adults aged 20 and older were included in this study from the city of Shiraz, Iran, from June to October 2015. The sampling was conducted using the stratified random sampling method. Active cigarette, hookah, and second-hand smokers were labeled as tobacco users in this study. Past smokers and non-smokers were labeled as non-tobacco users. The participants' socioeconomic status (SES) was determined based on their self-reported level of education, occupation, income, and residence., Results: In this study, 35.4% of the participants were tobacco users. The prevalence of active cigarette, active hookah, dual-users, and secondhand smokers was 13.3%, 8.3%, 0.4%, and 13.4%, respectively. The prevalence of tobacco use was highest among individuals with primary education level (40.9%), manual jobs (46.4%), lowest income level (38.1%), and those living in the suburban areas (36.4%). In multivariate analysis, the most socioeconomic factors related to tobacco usage were lack of academic education, manual job, and low-income level., Conclusions: Tobacco control efforts should be more focused on vulnerable groups of cigarette and hookah users in the southwest of Iran. Moreover, SES and reduction of health-related disparities and inequality should be considered a crucial concern in this regard., (© 2022 The Authors.

Background: Traditional hookah smoking has grown quickly to become a global tobacco epidemic. More recently, electronic hookahs (e-hookahs)-vaped through traditional water pipes-were introduced as healthier alternatives to combustible hookah. With combustible tobacco smoking, oxidative stress, inflammation, and vascular stiffness are key components in the development and progression of atherosclerosis. The comparable effects of hookah are unknown., Research Question: What is the differential acute effect of e-hookah vaping vs combustible hookah smoking on oxidation, inflammation, and arterial stiffness?, Study Design and Methods: In a randomized crossover design study, among a cohort of 17 healthy young adult chronic hookah smokers, we investigated the effect of e-hookah vaping and hookah smoking on measures of conduit arterial stiffness, including carotid-femoral pulse wave velocity (PWV), augmentation index-corrected for heart rate before and after a 30-min exposure session. We assessed a panel of circulating biomarkers indicative of inflammation and oxidants and measured plasma nicotine and exhaled carbon monoxide (CO) levels before and after the sessions., Results: e-Hookah vaping tended to lead to a larger acute increase in PWV than hookah smoking (mean ± SE: e-hookah, +0.74 ± 0.12 m/s; combustible hookah, +0.57 ± 0.14 m/s [P < .05 for both]), indicative of large artery stiffening. Compared with baseline, only e-hookah vaping induced an acute increase in augmentation index (e-hookah, +5.58 ± 1.54% [P = .004]; combustible hookah, +2.87 ± 2.12% [P = not significant]). These vascular changes were accompanied by elevation of the proinflammatory biomarkers high-sensitivity C-reactive protein, fibrinogen, and tumor necrosis factor α after vaping (all P < .05). No changes in biomarkers of inflammation and oxidants were observed after smoking. Compared with baseline, exhaled CO levels were higher after smoking than after vaping (+36.81 ± 6.70 parts per million vs -0.38 ± 0.22 parts per million; P < .001), whereas plasma nicotine concentrations were comparable (+6.14 ± 1.03 ng/mL vs +5.24 ± 0.96 ng/mL; P = .478)., Interpretation: Although advertised to be "safe," flavored e-hookah vaping exerts injurious effects on the vasculature that are, at least in part, mediated by inflammation., Trial Registry: ClinicalTrials.gov; No.: NCT03690427; URL: www.clinicaltrials.gov., (Copyright © 2021 The Author(s).

Background: The aim of this study was to investigate the association of denture stomatitis prevalence with cigarette, hookah and opium consumption and also dose-response relationship between the cigarette smoking duration and odds of denture stomatitis in population of Rafsanjan cohort center., Methods: This cross-sectional study based on data of Rafsanjan Cohort Study (RCS) with 10,000 participants. After applying inclusion and exclusion criteria, 1619 participants were included in the analysis. Data were collected by oral examination and completion of pre-designed questionnaires to assess denture hygiene, smoking behavior, opium use and some other exposure variables. Multivariable logistic regression models were fitted to investigate possible association of cigarette, hookah and opium consumption and denture stomatitis., Results: Prevalence of denture stomatitis among all 1619 denture wearers was 21.6%. Cigarette smoking was associated with a higher odds of denture stomatitis, with the adjusted odds ratio (95% CI) of 2.29 (1.53-3.41). Also, dose-response increases were observed with the highest odds ratio in the 4th quartile for denture stomatitis (p-value < 0.001). Opium consumption was associated with a decreased odds of denture stomatitis (adjusted OR; 0.81, 95% CI 0.58-1.13) which was not statistically significant. Also interaction between opium consumption and cigarette smoking was not associated with higher odds of denture stomatitis (adjusted OR: 1.65, 95% CI 0.85-3.22)., Conclusions: Based on the findings of the present study, while cigarette smoking had a dose-response relationship with the increased odds of denture stomatitis; this association was not found with opium consumption., (© 2021.

Hookah smoke is one of the major indoor sources of Volatile Organic Compounds (VOCs), including Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX). The present study aimed to investigate potential exposure to BTEX compounds among primary school children whose parents smoked hookah at home. BTEX concentrations in indoor air were measured in 60 residential buildings of Khesht, southwestern Iran (case = 30 and control = 30). Target compounds were sampled by charcoal tubes, and the samples were then analyzed by GC-FID. Monte Carlo simulation was used to assess the carcinogenic and non-carcinogenic risks of BTX exposure for the children aged 7-13 years. The concentrations of benzene (7.19 ± 3.09 vs. 0.82 ± 0.5 μg/m 3 ), toluene (1.62 ± 0.69 vs. 0.3 ± 0.22 μg/m 3 ), and xylenes (2.9 ± 1.66 vs. 0.31 ± 0.22 μg/m 3 ) were considerably higher in the indoor air of the case houses compared with the control houses (p < 0.05). The Incremental Lifetime Cancer Risk (ILCR) of benzene for non-smoking and smoking houses were estimated 1.8 × 10 -6 and 15 × 10 -6 , respectively, exceeding the recommendations of the World Health Organization (WHO) and the Environmental Protection Agency (EPA) (1 × 10 -6 ). Moreover, Hazard Quotients (HQs) of all BTX compounds were < 1. The indoor benzene concentration was significantly influenced by the floor at which families lived and type of the kitchen. In order to prevent children's exposure to BTX emitted by hookah, banning indoor smoking is the only way to eliminate these compounds in the indoor air., Competing Interests: Conflict of interestThe authors declare that they have no competing interests., (© Springer Nature Switzerland AG 2021.)

Purpose: The aim of this study is to explore the clinical relationship between the varicocele-associated male infertility with hookah smoking practice in the Saudi community in the al Jouf region., Materials and Methods: A total of 192 patients were categorized into two groups; varicocele with (Varicocele-Associated Hooka (VH) group; n = 100) and without smoking (NHV group; n = 92). Laboratory investigations such as hormonal (follicle-stimulating hormone, and luteinizing hormone [LH]), semen analysis were performed. Ultrasonography-based varicocele screening was performed. Data were analyzed with SPSS version 21.0. P < 0.05 was considered statistically significant., Results: Increased prevalence of varicocele Grade 2 (57%) and Grade 3 (52.5%) in HV groups. In contrast, Grade 1 was increased in NHV group (55.6%). A significant ( P = 0.05) decrease in testosterone levels in the HV group (2.83 ± 0.21) as compared to NHV group (2.33 ± 0.07) observed. Decreased levels of sperm count (21.96 ± 6.31) and sperm morphology (14.09 ± 0.45) were observed in HV groups as compared to NHV group (22.5 ± 5.49, 14.51 ± 5.02, respectively). HV groups showed the increased diameter of the testicular vein (3.52 ± 0.71) as compared to NHV group (3.42 ± 0.72). Chronic smoking revealed a statistically significant effect on testosterone ( P = 0.015) and LH levels ( P < 0.041) in the HV group. In addition, hookah smoking sessions per week affect sperm motility ( P = 0.02) in the HV group. A significant correlation was observed in sperm count ( r = 0.24, P < 0.016) and motility ( r = 0.25, P = 0.010) in HV group., Conclusion: Chronic hookah smoking significantly affects the reproductive hormonal and semen parameters in varicocele patients as compared to people with varicocele without smoking. This implies that hookah has an adverse effect on male reproductive and infertility., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Urology Annals.)

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., Competing Interests: Conflicts of interest statement The authors declare no conflict of interest., (©2021 Pacini Editore SRL, Pisa, Italy.)

This Study was designed to answer the question: what are the intervention goals of women for ceasing to smoke. The present research was part of a larger study and was a pioneering systematic research conducted between September 23, 2018 and September 26, 2019 through an intervention mapping in southern Iran among professional hookah Smoking (HS) women. In order to know more about the HS among women, the behavioral and environmental correlates of HS/cessation and the determiners or fundamental causes of these factors were extracted via a systematic review and a local qualitative study. As the results revealed, the expected outcomes of the educational program concerning hookah cessation were achieved. As the realization of these outcomes requires certain changes to the behavioral and environmental dimensions, in the next step, the intervention goals of hookah cessation were identified. As the results showed, four behavioral factors involved in the unhealthy HS behavior were individual HS, Being in the Company of hookah smokers, Visiting tempting and contaminated places and Physical and mental dependence on HS (habit), In addition, four effective environmental factors were found at different interpersonal, organizational, community and policy levels. These include, respectively: recommendation and motivation for cessation by influential figures, care providers' poor inadequate knowledge and skill, Easy acceptance of hookah in society, and the lack of effective rules. Knowledge, awareness, social norms, Motivation to comply, skill and self-efficacy, habit, were among the determining factors of hookah cessation. Employment of a systematic is based on evidence and cooperation and is guided by a assessing the needs of the target population. Such a method can suggest more purposive and relevant intervention goals so as to cease HS. The aim would be to intervene in the purposes of the above-mentioned change, as compared in predetermined interventions, and increase the chances of HS cessation among women.

The prevalence of hookah smoking has grown over the past decades in Iran especially in the south of the country. This study aimed to determine the behavioral and socio-demographic predictors of the hookah smoking frequency among women in southern Iran. This research was conducted on 400 women hookah smokers selected through multi-stage sampling method. Data were collected from October 2018 to September 2019 using a questionnaire guided by literature. Ordinal logistic regression analysis was run to determine the influential behavioral and socio-demographic predictors involved in the frequency of hookah smoking. Variables with a P-value of less than 0.05 in the final fitting model were associated with the outcome variable (frequency of hookah smoking per day1 = once a day, 2 = twice a day, 3 = three times a day, 4 = more than three times a day). We found that the longer duration of hookah smoking, family usage of hookah smoking, beginning to smoke hookah with peers, absence of either parent in family (single-parent families and a lack of prior intention to cease smoking), ever-married women and low socio-economic status (SES) predicted the frequency of hookah smoking. To prevent the behavior and make effective interventions to reduce hookah smoking, policy-makers should stay focused on factors other than internal motivations. Focus on the companies surrounding women smokers, quitting the habit of hookah smoking and effective interventions to decrease one's intention to smoke hookah can help reduce such unhealthy behaviors.

Background: Associations between hookah and opium use and an increased risk of ischemic heart disease (IHD) have been suggested in a few studies, but more research is needed on the nature of these associations. We aimed to investigate the association between hookah and opium use and the prevalence of IHD in a population with relatively high prevalence of these exposures in Iran., Methods: Using baseline data from the Pars Cohort Study (PCS), a prospective study of individuals aged 40-75 years in Fars province, southern Iran, we calculated adjusted and crude odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the independent association of hookah and opium use with prevalence of IHD., Results: Of 9248 participants, 10.2% (95% CI: 9.5, 10.9) had self-reported IHD. Prevalence of ever use of hookah and opium was 48.9% (95% CI: 44.6, 53.6) and 10.2% (95% CI: 8.3, 12.5) among those with IHD, and 37.0% (95% CI: 35.7, 38.3) and 8.1% (95% CI: 7.5, 8.7) among those without IHD, respectively. Adjusted OR for the association with prevalence of IHD was 1.26 (95% CI: 1.08, 1.46) for hookah use and 1.71 (95% CI: 1.30, 2.24) for opium abuse. No dose-response association was found between hookah and prevalence of IHD., Conclusion: Hookah and opium abuse were associated with prevalent IHD in this study. Although more research is needed on these associations, particularly in prospective settings, reducing hookah and opium use could potentially reduce IHD risk., (© 2020 The Author(s).

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.

Objectives: Electronic cigarettes (e-cigarettes) and waterpipes are gaining in popularity among adolescents in tandem with the increasing popularity of social networking sites (SNSs). The objective of this study was to examine the associations between the use of SNSs and e-cigarette and waterpipe use among adolescents, and to test whether these associations are independent of tobacco cigarette smoking., Study Design: A province-wide school-based cross-sectional study., Methods: Data were derived from the 2013 Ontario Student Drug Use and Health Survey. Our analyses included representative data from 2841 high school students across Ontario, Canada, who completed the questionnaire that included measures of lifetime use of e-cigarette and past-year use of waterpipe., Results: Nearly 14.6% of students reported having smoked an e-cigarette in their lifetime and 12.2% reported having smoked a waterpipe in the past year. After adjusting for various covariates, daily use of SNSs of at least 1 h/day was associated with greater odds of e-cigarette use (odds ratios ranged from 3.31 for SNS use of 1 h/day to 3.43 for ≥3 h/day), while daily use of SNSs of at least 2 h was associated with waterpipe use (odds ratios of 3.28 for SNS use of 2 h/day and 2.83 for use of ≥3 h/day). The observed associations remained significant after further adjusting for tobacco cigarette smoking., Conclusions: The use of SNSs was positively associated with e-cigarette and waterpipe use, independent of tobacco cigarette smoking. These findings highlight the need for including SNSs in ongoing prevention and intervention efforts., (Copyright © 2018 The Royal Society for Public Health. Published by Elsevier Ltd.

Background: Tobacco smoking is one of the most important public health problems that may be prevented. There is limited information about its relationship with communication skills. Findings on the relationships between self-esteem and cigarette/hookah smoking are inconsistent. The aim of this study was to investigate the relationships between cigarette and hookah smoking,self-esteem and communication skills among a representative sample of high school students. Methods: In this cross-sectional study, a sample of 1321 tenth-grade students (14-17 years) was selected through multi-stage proportionally cluster sampling in Tabriz, 2017. The participants completed a self-administered multiple choice questionnaire including questions about cigarette smoking, hookah smoking, self-esteem, and communication skills. Results: After controlling for potential confounders, the results demonstrated that higher score of self-esteem protects students against being in advanced stages of cigarette smoking (odds ratio [OR] = 0.95, 95% CI: 0.92-0.99, P=0.012). However, there was no significant association between self-esteem score and the hookah smoking. Also, there was no significant association between communication skills score and cigarette and hookah smoking. Conclusion: According to our findings, self-esteem was associated with cigarette smoking, but not with hookah smoking. Furthermore, there was no statistically significant association between communication skills score and cigarette and hookah smoking.

Introduction: Hookah smoking is becoming increasingly popular among the youth. Evidence shows that exposure to marketing of the unhealthy products through social media platforms may impact adolescent health behaviors. The aim of the study was to perform a content analysis of online portals selling hookah products., Materials and Methods: A content analysis of online retail market was conducted on Google India using three keywords hookah, hookah products, and shisha. Retail websites popular in India that were selling hookah products were randomly selected and explored. A total of 15 themes were developed and used to describe various promotional strategies for hookah products., Results: In all, 41 (19.2%) products claimed to be tobacco/nicotine-free and only 14 products (6.5%) displayed age/health-specific warnings. About 86% of products were available at discounted rates; glamorizing words for describing products in form of superior, premium, and legendary were found on 189 (88.3%) products. Phrases such as "ultimate way to celebrate," "perfect excuse to chill with your friends," and "now enjoy the world of smoking without any doubt of harm" are commonly used to promote hookah products., Conclusion: Easy availability of newer forms of smoking at online markets could play a role in promoting the use of hookah among the youth. Most products are being sold without any warnings and there is no means to control the selling of the products to minors. There is a need to raise the issue of hookah products in the same tune as done for other forms of tobacco., Competing Interests: None

Setting: During a period of regulatory uncertainty, a local public health unit in Ontario was notified of an exhibition for electronic nicotine delivery systems (ENDS) and novel tobacco delivery products (NTDs), specifically e-cigarettes and waterpipes, which have seen increasing use particularly among youth. Relevant statutes creating regulatory uncertainty included a new provincial Electronic Cigarettes Act (ECA) with certain sections awaiting proclamation, and a local waterpipe bylaw awaiting approval, which would have prohibited the use of these products in public spaces if they entered into force ahead of the exhibition date. Public health staff had concerns the event would normalize use of ENDS/NTDs, particularly among youth, and also planned to enforce already proclaimed ECA sections, as well as the existing Smoke-Free Ontario Act (SFOA) with regulations applicable to use of tobacco shisha in waterpipes., Intervention: Public health staff contacted event organizers and proprietors to communicate obligations under the SFOA and ECA, as well as share hypothetical implications from pending regulatory changes, including risk of charges for regulatory non-compliance if regulations came into force ahead of the planned event., Outcomes: Following discussion with health unit staff and legal consultation, the exhibition was cancelled., Implications: By directly communicating regulatory uncertainty, a public health unit was able to achieve local health goals. In this situation, public health advised exhibition proprietors of potential event disruption implicated by forthcoming regulatory changes. Subsequent cancellation of the event prevented potential adverse health impacts for at-risk groups. A similar communications approach could be used to achieve public health goals during a period of regulatory uncertainty.

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. Hookah smoking is growing worldwide and particularly in Iran. The aim of this study was to determine the prevalence of obstructive pulmonary dysfunction in hookah smokers. We conducted a population-based study in Bushehr Province, Iran. A total of 245 subjects aged 35 years or older who were taking hookah for at least 15 years and 245 healthy controls were enrolled in the study and spirometry was done. Statistical analyses were performed using SPSS for windows software version 19. The prevalence of COPD among the exposed group of hookah smoke was 10.2%, with the rate being significantly higher in the patients with older age ( p < 0.001), duration of hookah smoking ( p < 0.001), men ( p = 0.026), ≥3 hookahs/day ( p = 0.006), history of cough for ≥2 years ( p = 0.002), in patients with a history of sputum for ≥2 years ( p = 0.031), and in patients with a history of dyspnea for ≥2 years ( p = 0.001). The results of the logistic regression analysis demonstrated that older age, male gender, smoking, and occupational exposure were independent predictive factors for COPD. The results of our study suggest that hookah smoking significantly increases the risk of COPD. Given the importance of COPD in the global burden of diseases, it is necessary to carry out further studies on the relationship between hookah use and COPD.

Background: Transtheoretical model (TTM) has been recognized as a common theoretical model in researches in terms of addictive behaviors. The aim of this study was to examine the psychometric properties of the Persian brief version of the TTM for hookah tobacco smoking cessation in a sample of Iranian rural adults who were in the preparation stage for hookah cessation., Methods: This was a validation study on Iranian rural adult hookah smokers by the TTM instrument. First, to translate the questionnaire items from English to Persian, backward-forward procedure was used. Face and content validity of the instrument items were assessed. Confirmatory factor analysis (CFA) was performed to determine the construct validity of the instrument. For this aim, 300 participants completed the instrument. Cronbach's alpha coefficient and intraclass correlation coefficient (ICC) were calculated to examine the internal consistency and reliability of the subscales of the instrument., Findings: The content validity index (CVI) and content validity ratio (CVR) of the items were ≥ 0.80 and ≥ 0.60, respectively. Based on CFA, the data fitted the TTM model. root mean square error of approximation (RMSEA), the goodness of fit index (GFI), adjusted GFI, and comparative fit index (CFI) were 0.037, 0.960, 0.910, and 0.950, respectively. At this stage, 6 items were deleted. The ICC and Cronbach's alpha of the subscales ranged between 0.60-0.74 and 0.71-0.86, respectively. The final instrument with 29 items was confirmed., Conclusion: The findings suggest that translating Persian brief version of the TTM instrument was a reliable and valid tool to identify the determinants of hookah smoking cessation among Iranian rural adults.

Objectives: Recent research has described negative relationship between happiness and habitual smoking among adolescents. No study of this relationship has been conducted among Iranian adolescents. The aim of the present study was to characterize the relationship between happiness and cigarette or hookah smoking among a sample of high school students., Methods: A sample of 1,161 10th-grade students in Tabriz (northwest Iran) was selected by multi-stage proportional cluster sampling. Participants completed a self-administered multiple-choice questionnaire including information on cigarette smoking, hookah smoking, happiness score, substance abuse, self-injury, general risk-taking behavior, attitudes towards smoking, socioeconomic information, and demographic characteristics. An ordinal logistic regression model was used for data analysis., Results: It was found that 5.9 and 5.0% of students were regular cigarette smokers and regular hookah smokers, respectively. After controlling for potential confounders, higher happiness scores were found to protect students against more advanced stages of cigarette smoking (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97 to 0.99; p=0.013). However, no significant relationship was found between happiness scores and hookah smoking status (OR, 1.01; 95% CI, 0.97 to 1.02; p=0.523)., Conclusions: Happiness scores were associated with less advanced stages of habitual cigarette smoking among high school students. Our findings underscore the necessity of conducting longitudinal or interventional studies aiming to determine the effects of enhancing happiness on preventing the transition through the stages of cigarette and hookah smoking.

Background: Nicotine, an addictive drug, is present in all forms of tobacco products, including hookah tobacco, which is not yet regulated in the United States., Objectives: This study aimed to investigate the uptake of nicotine in hookah smokers and non-smokers exposed to secondhand smoke (SHS) at indoor hookah social events in natural settings where hookah tobacco was smoked exclusively., Patients and Methods: We quantified cotinine, a metabolite of nicotine, in the urine of 105 hookah smokers and 103 non-smokers. Participants provided spot urine samples the morning of and the morning after attending an indoor hookah-only smoking social event at a hookah lounge or in a private home., Results: Following a social event where exclusively hookah tobacco was smoked, urinary cotinine levels increased significantly 8.5 times (geometric mean (GM): 16.0 ng/mg to 136.1 ng/mg) among hookah smokers, and 2.5 times (GM: 0.4 ng/mg to 1.0 ng/mg) among non-smokers exposed exclusively to hookah tobacco SHS. Among hookah smokers, the highest increase in urinary cotinine levels post a hookah event was found in occasional hookah smokers in which GM levels increased significantly 31.2 times post smoking (from 2.0 ng/mg to 62.3 ng/mg). Reported reasons for preference to smoke hookah at home by hookah smokers who attended a hookah social event in a private home included recreational purposes, socializing with friends and family, 'Me' time and relaxing at home, more comfortable to smoke hookah at home, owning a hookah and hookah tobacco, eating and drinking while smoking hookah, and saving money by smoking at home and not going to hookah lounges., Conclusions: Hookah tobacco smoke is a source of substantial nicotine exposure. Our results call for protecting hookah smokers' and non-smokers' health by requiring accurate hookah tobacco labels, raising taxes on hookah tobacco, reducing the spread of hookah lounges, and encouraging voluntary bans on smoking hookah tobacco in private homes., Competing Interests: Declaration of Interests: The authors declare no competing interests associated with this study.

Background: This study explores the differences among smokers of waterpipe tobacco in a college population to better inform campaigns to curb waterpipe use., Methods: Participants included undergraduate and graduate students attending a liberal arts university in Florida. E-mail-based, cross-sectional surveys were collected in 2 sequential years., Results: The majority of respondents (64%) reported having ever smoked a hookah, even if just 1-2 puffs. Of those who had ever smoked a hookah, 34% reported smoking a hookah within the previous 30 d. Constructs from the theory of reasoned action were all correlated with smoking behavior. The range of beliefs endorsed by smokers were more strongly associated with hookah-related attitudes compared with subjective norms. Concerns about health were stronger among never-smokers., Conclusions: Young adult college students continue to engage in waterpipe tobacco smoking at high rates. Campaigns need to focus on subsets of smokers and nonsmokers, independently., (Copyright © 2017 by Daedalus Enterprises.)

Background: These days, hookah smoking has gained popularity among people in many communities, especially among youths and students, and more attention to this issue seems necessary. The purpose of this study was to determine the factors affecting hookah smoking among Sabzevar Azad University students., Methods: This cross-sectional study was conducted on university students in Sabzevar, Iran in 2014. The questionnaire was developed and its validity and reliability were assessed. Three hundred six male students of Sabzevar Azad University were selected by simple random sampling and questionnaires were filled out by them. The collected data were analyzed by SPSS software and the Chi-Square and Independent-samples t-test., Results: The results showed that 47.7% of the participants had a history of smoking hookah. The main factors affecting hookah smoking from participants' point of view were: filling leisure time, availability of hookah, positive social appearance, friends' invitation and relief from anxieties. Chi-Square tests showed that there was no significant relationship between fathers' level of education (p=0.41), mothers' level of education (p=0.46), fathers' job (p=0.18), mothers' job (p=0.53) and students' current grade (p=0.41) with hookah smoking. The study showed significant relationship between present hookah smoking and awareness about complications of the hookah (p=0.01)., Conclusion: Interventions to reduce and quit hookah smoking among students should include several items, such as teaching problem-solving skills to fill leisure time properly and to deal with the temptation of hookah smoking, as well as teaching refusal skills at the invitation of friends for hookah., Competing Interests: There is no conflict of interest to be declared.

Background: The rise in popularity of electronic cigarettes (e-cigarettes) and hookah over recent years has been accompanied by some confusion and uncertainty regarding the development of an appropriate regulatory response towards these emerging products. Mining online discussion content can lead to insights into people's experiences, which can in turn further our knowledge of how to address potential health implications. In this work, we take a novel approach to understanding the use and appeal of these emerging products by applying text mining techniques to compare consumer experiences across discussion forums., Objective: This study examined content from the websites Vapor Talk, Hookah Forum, and Reddit to understand people's experiences with different tobacco products. Our investigation involves three parts. First, we identified contextual factors that inform our understanding of tobacco use behaviors, such as setting, time, social relationships, and sensory experience, and compared the forums to identify the ones where content on these factors is most common. Second, we compared how the tobacco use experience differs with combustible cigarettes and e-cigarettes. Third, we investigated differences between e-cigarette and hookah use., Methods: In the first part of our study, we employed a lexicon-based extraction approach to estimate prevalence of contextual factors, and then we generated a heat map based on these estimates to compare the forums. In the second and third parts of the study, we employed a text mining technique called topic modeling to identify important topics and then developed a visualization, Topic Bars, to compare topic coverage across forums., Results: In the first part of the study, we identified two forums, Vapor Talk Health & Safety and the Stopsmoking subreddit, where discussion concerning contextual factors was particularly common. The second part showed that the discussion in Vapor Talk Health & Safety focused on symptoms and comparisons of combustible cigarettes and e-cigarettes, and the Stopsmoking subreddit focused on psychological aspects of quitting. Last, we examined the discussion content on Vapor Talk and Hookah Forum. Prominent topics included equipment, technique, experiential elements of use, and the buying and selling of equipment., Conclusions: This study has three main contributions. Discussion forums differ in the extent to which their content may help us understand behaviors with potential health implications. Identifying dimensions of interest and using a heat map visualization to compare across forums can be helpful for identifying forums with the greatest density of health information. Additionally, our work has shown that the quitting experience can potentially be very different depending on whether or not e-cigarettes are used. Finally, e-cigarette and hookah forums are similar in that members represent a "hobbyist culture" that actively engages in information exchange. These differences have important implications for both tobacco regulation and smoking cessation intervention design.

Background: Given the increasing evidence of its negative health effects, including contributions to both infectious and chronic diseases, waterpipe tobacco smoking raises public health concerns beyond even those presented by traditional smoking., Methods: Identification of Clean Indoor Air Acts (CIAAs) from each of the 50 United States and District of Columbia were retrieved and examined for inclusion of regulatory measures where waterpipe tobacco smoking is concerned. Several instances of exemption to current CIAAs policies were identified. The cumulative policy lens is presented in this study., Results: States vary in their inclusion of explicit wording regarding CIAAs to the point where waterpipe tobacco smoking, unlike traditional smoking products, is excluded from some legislation, thereby limiting authorities' ability to carry out enforcement., Conclusion: Consistent, comprehensive, and unambiguous legislative language is necessary to prevent establishments where waterpipe tobacco smoking occurs from skirting legislation and other forms of regulatory control. Stricter laws are needed due to the increasing negative health impact on both the smoker and the bystander. Actions at both the federal and state levels may be needed to control health risks, particularly among youth and young adult populations.

Objective: To examine baseline characteristics and biochemically verified 1-, 4-, and 6-month tobacco quit rates among college students enrolled in a Quit and Win cessation trial, comparing those who concurrently smoke both hookah and cigarettes with those who deny hookah use., Methods: Analyses were conducted on data from 1217 college students enrolled in a Quit and Win tobacco cessation randomized clinical trial from 2010-2012. Multivariable logistic regression (MLR) analyses examined group differences in baseline characteristics and cotinine verified 30-day abstinence at 1, 4, and 6-month follow-up, adjusting for baseline covariates., Results: Participants smoked 11.5(±8.1) cigarettes per day on 28.5(±3.8) days/month, and 22% smoked hookah in the past 30days. Hookah smokers (n=270) were more likely to be male (p<0.0001), younger (p<0.0001), report more binge drinking (p<0.0001) and score higher on impulsivity (p<0.001). MLR results indicate that hookah users, when compared to non-users, had a 36% decrease in odds of self-reported 30-day abstinence at 4-months (OR=0.64, 95% CI=0.45-0.93, p=0.02) and a 63% decrease in odds in biochemically verified continuous abstinence at 6-months (OR=0.37, CI=0.14-0.99, p=0.05)., Conclusion: College cigarette smokers who concurrently use hookah display several health risk factors and demonstrate lower short and long-term tobacco abstinence rates., (Copyright © 2015.

Objectives: Waterpipe tobacco smoking (WTS) is a growing public health concern worldwide yet little is known about the epidemiology of use among young people. The objectives of this study were to examine the prevalence, patterns and correlates of WTS among students across Lebanon., Study Design: The study design was a cross sectional survey., Methods: 126-item tobacco questionnaire was conducted among 1128 sixth and seventh grade students across Lebanon. Current patterns of use were descriptively analysed, and logistic regression models examined correlates of WTS., Results: Ever WTS prevalence was 44.3%, current WTS prevalence was triple that of cigarettes (22.1% vs 7.4%), and 40.0% of current users were at least weekly or daily smokers. Initiation and patterns of use, as well as addiction and cessation attitudes have been reported. Significant correlates of current WTS included older age, reduced religiosity, peer and parent tobacco use, recent waterpipe advertisement exposure, increased pluralistic ignorance and current cigarette use. Significant correlates of ever WTS were similar to current WTS, but included second hand waterpipe tobacco smoke exposure at home and did not include recent waterpipe advertisement exposure. Neither gender nor socio-economic status were significant correlates of current or ever WTS., Conclusions: Waterpipe is the most common form of tobacco smoking, and is used regularly, among sixth and seventh grade Lebanese students. It should be considered a public health priority with increased tobacco surveillance and legislation. Widespread educational and policy interventions might help denormalize the social acceptability of WTS. Meanwhile, more research is needed to understand the changing paradigm of WTS epidemiology and the health outcomes among young smokers., (Copyright © 2015 The Royal Society for Public Health.

Objective: To examine waterpipe use and its association with demographic factors, tobacco cigarette smoking, ever use of electronic cigarettes (e-cigarettes) and alcohol use among high school students., Methods: Data were derived from the 2013 Ontario Student Drug Use and Health Survey, a school-based survey of 7th to 12th grade students. This province-wide survey was based on a stratified two-stage cluster design. Analyses were based on a subsample of 2,873 high school students and included adjustments for the complex sample design., Results: Overall, 12.5% of high school students (grades 9-12) had used a waterpipe in the previous year. Awareness of waterpipes was high - 68.4% of students reported that they were aware of waterpipes but had not used one in the past year; 19.1% had never heard of waterpipes or hookah. The percentage of high school students reporting waterpipe use in the past year was similar to reports of tobacco cigarette use (12.5% and 11% respectively). Waterpipe use was highly associated with past-year tobacco cigarette and regular alcohol use as well as ever use of e-cigarettes. In multivariate analyses, males and females had similar odds of waterpipe use, and non-White students and those in higher grades had greater odds of use after controlling for other substance use., Conclusion: These findings suggest that waterpipe use among high school students should be of some concern and suggest the need for policy measures to address potential risks associated with use.

Background: The aim of the study was to determine predictors of refraining from hookah smoking among high-school students in Bandar Abbas, southern Iran based on Prototype/Willingness model., Methods: This cross- sectional with analytic approach was performed on 240 high-school students selected by a cluster random sampling. The data of demographic and Prototype-Willingness Model constructs were acquired via a self-administrated questionnaire. Data were analyzed by mean, frequency, correlation, liner and logistic regression statistical tests., Results: Statistically significant determinants of the intention to refrain from hookah smoking were subjective norms, willingness, and attitude. Regression model indicated that the three items together explained 46.9% of the non-smoking hookah intention variance. Attitude and subjective norms predicted 36.0% of the non-smoking hookah intention variance. There was a significant relationship between the participants' negative prototype about the hookah smokers and the willingness to avoid from hookah smoking (P=0.002). Also willingness predicted non-smoking hookah better than the intention (P<0.001)., Conclusion: Deigning intervention to increase negative prototype about the hookah smokers and reducing situations and conditions which facilitate hookah smoking, such as easy access to tobacco products in the cafés, beaches can be useful results among adolescents to hookah smoking prevention.

Objectives: To investigate the acute cardiovascular effects of smoking shisha., Design: A cross-sectional study was carried out in six shisha cafes. Participants smoked shisha for a period between 45 min (minimum) and 90 min (maximum). The same brand of tobacco and coal was used., Setting: London, UK., Participants: Participants were those who had ordered a shisha to smoke and consented to have their blood pressure, heart rate and carbon monoxide levels measured. Excluded subjects were those who had smoked shisha in the previous 24 h, who smoke cigarettes or who suffered from cardiorespiratory problems., Main Outcome Measures: Blood pressure was measured using a sphygmomanometer. Pulse was measured by palpation of the radial artery. Carbon monoxide levels were obtained via a carbon monoxide monitor. These indices were measured before the participants began to smoke shisha and after they finished or when the maximum 90 min time period was reached., Results: Mean arterial blood pressure increased from 96 mmHg to 108 mmHg (p < 0.001). Heart rate increased from 77 to 91 bpm (p < 0.001). Carbon monoxide increased from an average of 3 to 35 ppm (p < 0.001). A correlation analysis showed no relationship between carbon monoxide and the other indices measured., Conclusion: The acute heart rate, blood pressure and carbon monoxide levels were seen to rise significantly after smoking shisha. The weak correlation between carbon monoxide levels and the other variables suggests that carbon monoxide levels had not contributed to their significant increase.

Objective: Noncigarette tobacco products are increasingly popular. Researchers need to understand multiple tobacco product use to assess the effects of these products on population health. We estimate national prevalence and examine risk factors for multiple product use., Method: We calculated prevalence estimates of current use patterns involving cigarettes, cigars, electronic cigarettes, hookah, smokeless tobacco, and snus using data from the 2012 RTI National Adult Tobacco Survey (N=3627), a random-digit-dial telephone survey of adults aged 18 and over. Associations between use patterns (exclusive single product and multiple products) and demographic characteristics were examined using Pearson chi-square tests and logistic regression., Results: 32.1% of adults currently use 1 or more tobacco products; 14.9% use cigarettes exclusively, and 6.6% use one noncigarette product exclusively, 6.9% use cigarettes with another product (dual use), 1.3% use two noncigarette products, and 2.4% use three or more products (polytobacco use). Smokers who are young adult, male, never married, reside in the West, and made prior quit attempts were at risk for multiple product use., Conclusions: Over 10% of U.S. adults use multiple tobacco products. A better understanding of multiple product use involving combustible products, like cigars and hookah, is needed. Multiple product use may be associated with past quit attempts., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Background: Waterpipe tobacco smoking (WTS) popularity is increasing world-wide, and health effects are emerging in the light of evidence that WTS is perceived by users as less harmful than cigarette smoking. However, there remains a paucity of available evidence from which to draw firm conclusions about its public health significance., Aims: This narrative review aims to summarize WTS literature to date to inform tobacco control specialists and health-care professionals about this phenomenon and help them to assess whether or not WTS should become a public health priority., Methods: Standard electronic databases as well as conference proceedings and personal libraries were searched in English, French and Arabic with inclusive terminology for the variety of names given to WTS., Findings: Waterpipe smoke contains significant levels of toxins, some of which are known to be carcinogenic to humans. Recent epidemiological trends have established an increasing prevalence of WTS in the Middle East and the United States, particularly among adolescents. It is used commonly across multiple ethnicities and both genders with less of a social gradient than cigarette smoking. Attitudes and beliefs have been researched widely and several reasons for believing it is less harmful than cigarette smoking include water filtration and social acceptability. A wide range of diseases have been associated with WTS, but research in this area is relatively underdeveloped and a better evidence base is needed. Worryingly, the waterpipe industry, including waterpipe cafes, operates in an almost completely unregulated market and employs deceptive marketing techniques to attract new users., Conclusions: Waterpipe tobacco smoking (WTS) appears to be on the increase, especially among younger users, and therefore represents a potential public health concern. While legislators should consider enforcing and extending existing tobacco laws to a growing WTS industry, further research is required to fill gaps in the literature and provide evidence-based interventions for tobacco control specialists and health-care professionals., (© 2013 Society for the Study of Addiction.)
