Discussion of waterpipe tobacco smoking on reddit

Objectives

This study aimed to examine public discussions of waterpipe tobacco smoking, as well as the potential associations of different waterpipe flavors with health symptoms, using Reddit data.

Study design

This is an observational infodemiology study.

Methods

Using keywords such as “waterpipe”, “hookah”, and “shisha”, Reddit posts were extracted from Reddit Archive (pushshift.io) between February 1, 2016, and December 31, 2020. Temporal analysis was used to understand the longitudinal trend of the discussions about waterpipe tobacco smoking. Topic modeling using the Latent Dirichlet Allocation (LDA) model was performed to examine the topics on waterpipe tobacco. We estimated the conditional probability of having each health problem for each given waterpipe flavor.

Results

The discussion of waterpipe on Reddit was slowly decreasing from 2016 to 2018 and surged until May 2020. The fruit was the most popular waterpipe flavor and the neurological symptom was the most mentioned health category in waterpipe-related Reddit posts. The most popular topics included “Friends spending time together at night with waterpipe smoking”, “Playing games and smoking waterpipe at a hookah bar”, and “Discussing waterpipe flavors and related products”. Some waterpipe flavors were more associated with certain health problems than others. For example, mint/menthol flavor had a high probability to be associated with symptoms related to throat and mouth.

Conclusion

This study provided longitudinal surveillance of waterpipe tobacco smoking discussed on Reddit. We showed the potential relationship between waterpipe flavors and health symptoms, which provides preliminary evidence about the potential health effects of waterpipe tobacco smoking.

Motivators of impulsivity to smoke waterpipe tobacco among Nigerian youth who smoke waterpipe tobacco: the moderating role of social media normalisation of waterpipe tobacco

Background

Impulsivity is a formidable cause of waterpipe tobacco smoking among youth, however, it is understudied among African youth. Using PRIME behavioural theory, this study aimed to develop a model that examines the motivators of impulsivity to smoke waterpipe tobacco in linkage to the moderating role of social media normalisation of waterpipe tobacco, specifically among youth in Nigeria who smoke waterpipe tobacco.

Methods

Data were drawn from 695 respondents who smoke waterpipe tobacco across six Nigerian universities in the South-West zone using the chain-referral sampling procedure. Descriptive analyses of the obtained data were carried out using the Statistical Package for Social Sciences (SPSS) version 25. The constructs in the developed model were validated through Partial Least Squares Structural Equation Modelling (PLS-SEM) in SmartPLS version 3.

Results

Among Nigerian youth who smoke waterpipe tobacco, intention (β = 0.442, P < 0.001) was the strongest motivator of impulsivity to smoke waterpipe tobacco as compared to positive evaluations (β = 0.302, P < 0.001). In addition, social media normalisation of waterpipe tobacco acted as a moderator that strengthened the relationship between intention and impulsivity (β = 0.287, P < 0.01), as well as, between positive evaluations and impulsivity (β = 0.186, P < 0.01) among youth.

Conclusion

Intention greatly instigates Nigerian youth’s impulsivity to smoke waterpipe tobacco, and social media normalisation of waterpipe tobacco also considerably increases their impulsivity to smoke waterpipe tobacco. Youth-focused educational waterpipe tobacco cessation-oriented programmes that utilise diverse constructive-based learning approaches like illustrative learning and counselling, can help to enlighten and encourage Nigerian youth on the importance of shunning the desirability to smoke waterpipe tobacco.

Exercise Training Attenuates Cardiac Vulnerability and Promotes Cardiac Resistance to Isoproterenol-Induced Injury Following Hookah Smoke Inhalation in Male Rats: Role of Klotho and Sirtuins

Hookah smoking is on the rise around the world. Present study investigated the heart resistance to harmful stress following long-term waterpipe tobacco smoking (WTS) and moderate-intensity exercise training intervention in male Wistar rats. Animals were randomly divided into a non-ischemic heart control group and four ischemic heart groups including ISO (isoproterenol-treated), Ex + ISO (subjected to exercise plus ISO), S + ISO (exposed to hookah smoke plus ISO), and Ex + S + ISO (subjected to exercise along with hookah smoke plus ISO). After eight weeks of training and WTS, heart ischemia induced by isoproterenol injections. Then, cardiac functional indices and some biochemical and histopathological parameters were assessed. WTS + ISO reduced systolic pressure, ± dP/dt max, and contractility indices (P < 0.001 vs. ISO group) and increased end diastolic pressure and Tau index (P < 0.001 vs. ISO) of the left ventricle. Also, WTS + ISO was associated with an increase in Bax protein level and Bax/Bcl-2 ratio (P < 0.05 and P < 001, respectively, vs. ISO group) as apoptotic markers of heart tissue. Hookah smoke significantly decreased SIRT1 (P < 0.05 and P < 0.001, respectively, vs. ISO) and klotho (P < 0.01 and P < 0.001, respectively, vs. ISO) in serum and heart, and SIRT3 and pS9-GSK-3β (P < 001 and P < 0.05, respectively, vs. ISO) in heart tissue. Combination of exercise with WTS prevented the hookah smoke-induced alterations in apoptotic markers, cardiac functional indices, and SIRT1, SIRT3, klotho, and pS9-GSK-3β proteins. The findings demonstrated that hookah smoke inhalation intensifies ventricular dysfunction and decreases heart resistance to harmful stresses. Moderate-intensity exercise training attenuated these complications partly through recovering the klotho and sirtuins levels and apoptosis-survival balancing.

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.

Sociocultural factors contributing to waterpipe tobacco smoking among adolescents and young adult women: a qualitative study in Iran

Purpose: Waterpipe tobacco smoking (WTS) is currently a serious and growing public health threat in the world, especially in adolescents and young women. The aim of the study was to explore sociocultural factors contributing to WTS among adolescents and young adult women in Iran.

Methods: This qualitative study was conducted from August 2017 to January 2019 in Isfahan and Hamadan cities, Iran; it included 13–30-year-old females with experience of WTS. For data collection, in-depth semi-structured personal interviews were conducted at participants’ preferred time and place. Concurrent with data collection, data were analysed through conventional content analysis.

Results: The study participants described the various sociocultural factors contributing to WTS. These factors were categorized into four following main categories: waterpipe glamorization by its producers and sellers, media advertisement or silence, common sociocultural traditions, and governmental policies and regulations.

Conclusion: A wide range of sociocultural factors affects WTS among Iranian adolescents and young adult women. Therefore, interdisciplinary multidimensional strategies are needed for WTS management and prevention among these at-risk groups. Public education, strict supervision of tobacco import, export, and selling, ample employment opportunities for young people and effective leisure time management are essential to reduce WTS.Abbreviation WTS: Waterpipe Tobacco Smoking; MPOWER: Monitor tobacco use and prevention policies, Protect people from tobacco smoke, Offer help to quit tobacco use, Warn about the dangers of tobacco, Enforce bans on tobacco advertising, promotion and sponsorship, Raise taxes on tobacco

Knowledge of health professional students on waterpipe tobacco smoking: curricula implications

BACKGROUND

Tobacco prevention research traditionally focuses upon cigarette smoking, but there is also a need to implement and evaluate the usefulness of waterpipe tobacco smoking (WTS) interventions since it is considered less harmful than cigarettes. This study aimed to assess the impact of an educational intervention on WTS knowledge of health professional students in three academic health institutions in Bahrain.

METHODS

A quasi-experimental design was used to include medical students from the Arabian Gulf University, medical and nursing students from the Royal College of Surgeons in Ireland-Bahrain and nursing students from the University of Bahrain. Two hundred fifty students participated in the three phases of the study during October 2015-June 2016 from an original sample of 335. The participants answered knowledge questions on WTS before and after an intervention, which included a lecture by an expert and a video on the awareness about the health hazards of WTS.

RESULTS

The mean age of starting cigarette and WTS was 16.8 ± 2.8 and 17.5 ± 1.7 years, respectively. The prevalence of ever smoking any type of tobacco among students was 22.4% (medical 25.8% and nursing 37.5%) and that of WTS, 17.7% (medical 20.0%, nursing 13.6%). The prevalence of current cigarette smoking was 9.6% among medical and nursing students combined with 10.3 and 8.5% for medical and nursing students, respectively. WTS was prevalent at a proportion of 6.8% among medical and nursing students combined with 6.5% in medical and 14.8% in nursing students. The university curriculum as the main source of knowledge on WTS increased from 14.2 to 33.3% after the intervention (p < 0.005). Knowledge about the hazards of WTS increased in 16 of the 20 statements. The difference in overall knowledge score was significant (p < 0.05) for nursing (77. 5 ± 1.5 vs 85.8 ± 2.2) compared to medical students (85.3 ± 1.0 vs 87.3 ± 0.9) after the intervention.

CONCLUSIONS

Our educational intervention with health professional students improved their knowledge about the health effects of WTS. Medical and nursing institutions may consider using various methods such as informative videos and expert lectures to include in their teaching curricula as part of WTS prevention strategies.

The effects of waterpipe tobacco smoking on health outcomes: an updated systematic review and meta-analysis

Background and aims

A systematic review conducted in 2008 found significant associations between waterpipe tobacco smoking and lung cancer, respiratory disease, periodontal disease and low birthweight. Since then, a number of relevant studies have been published. The objective of this study was to update the systematic review on the effects of waterpipe tobacco smoking on health outcomes.

Methods

In May 2015 we electronically searched the following databases with no date restrictions: MEDLINE, EMBASE and the ISI Web of Science using a detailed search strategy with no language restrictions. We also screened the references' lists of the included studies. We included cohort, case-control and cross-sectional studies, and excluded case reports, conference abstracts, editorials and reviews. We excluded studies not conducted in humans, assessing physiological outcomes, not distinguishing waterpipe tobacco smoking from other forms of smoking or not reporting association measures. We assessed risk of bias for each included study and conducted meta-analyses for each of the outcomes of interest.

Results

We identified 50 eligible studies. We found that waterpipe tobacco smoking was significantly associated with: respiratory diseases [COPD; odds ratio (OR) = 3.18, 95% confidence interval CI = 1.25, 8.08; bronchitis OR = 2.37, 95% CI = 1.49, 3.77; passive waterpipe smoking and wheeze OR) = 1.97, 95% CI = 1.28, 3.04]; oral cancer OR = 4.17, 95% CI = 2.53, 6.89; lung cancer OR = 2.12, 95% CI = 1.32, 3.42; low birthweight (OR = 2.39, 95% CI = 1.32, 4.32); metabolic syndrome (OR 1.63-1.95, 95% CI = 1.25, 2.45); cardiovascular disease (OR = 1.67, 95% CI = 1.25, 2.24); and mental health (OR 1.30-2.4, 95% CI = 1.20, 2.80). Waterpipe tobacco smoking was not significantly associated with: oesophageal cancer (OR = 4.14, 95% CI = 0.93, 18.46); worse quality of life scores [standardized mean difference (SMD) = -0.16, 95% CI = -0.66, 0.34]; gastric carcinoma (OR = 2.16, 95% CI = 0.72, 6.47); bladder cancer (OR = 1.25, 95% CI = 0.99, 1.57); prostate cancer (OR = 7.00, 95% CI = 0.90, 56.90); hepatitis C infection (OR = 0.98, 95%0.80, 1.21); periodontal disease (OR = 3.00, 5.00); gastro-oesophageal reflux disease (OR = 1.25, 95% CI = 1.01, 1.56); nasopharyngeal carcinoma (OR = 0.49, 95% CI = 0.20, 1.23); bladder cancer (OR = 1.25, 95% CI = 0.99, 1.57); infertility (OR = 2.50, 95% CI = 1.00, 6.30); and mortality (OR = 1.15, 95% CI = 0.93, 1.43).

Conclusions

There is accumulating evidence about the association of waterpipe tobacco smoking with a growing number of health outcomes.

Smoking behavior of males attending the quit tobacco clinics in Bahrain and their knowledge on tobacco smoking health hazards

Background

One third of Bahraini adult (20–64 years) males and 7.0% of females use some form of tobacco. The corresponding rates for cigarette and waterpipe tobacco smoking (WTS) are 11.0% and 6.0%, respectively. The objective of the study was to determine the knowledge on tobacco smoking and past smoking related behavior of male patients attending the Quit Tobacco Clinics (QTC) in Bahrain.

Methods

A sample of 339 male clinic attendees was taken proportional to the population distribution in the three QTC at Al Hoora Health Center, Hamad Kanoo Health Center, and Bank of Bahrain and Kuwait Health Center. Data collection was performed until the sample size was completed (September 2015 to December 2016). Knowledge on the health effects of cigarette and WTS was examined based on 10 statements on cigarette and similar ones on WTS. Respondents “agreeing” with the statements were considered knowledgeable and those “disagreeing” or responding “don’t know”, not knowledgeable. All the “agree” responses for cigarette/WTS were summed across the 10 health effects and average health knowledge scores for cigarette/WTS were computed.

Results

Most of the study participants were Bahraini nationals, ever married and educated with at least secondary level. The majority (65.8%) of participants smoked a single type of tobacco product, and the rest, two (28.0%) or three or more (6.2%). Age of starting cigarette and WTS was 16.2 ± 4.0 and 19.3 ± 6.7 years, respectively. The majority (81%) smoked in the presence of other family members and 26.3% in the presence of a child. 76.2% smoked in the presence of others in their cars. 18.9% of the attendees had quit smoking at the time of interview. 81% of the participants knew about the hazards of both cigarette and WTS with a significantly higher (p = 0.0001) mean knowledge score for cigarette (93.3 ± 3.0%) than WTS (85.2 ± 2.1%).

Conclusion

The relative lack of knowledge on the hazards of WTS in a sample of Arab country population with an increasing trend of WTS warrants the attention of health policy makers in the country and region.

Waterpipe and cigarette tobacco smoking among Palestinian university students: a cross-sectional study

BACKGROUND

During the last two decades, waterpipe tobacco smoking (WTS), also known as hookah, witnessed a global increase in use, especially among youth. Little information is known about the burden of WTS among Palestinian youth. A cross-sectional study was conducted to estimate the prevalence of WTS and cigarette smoking and explore the associated factors among a sample of Palestinian university students.

METHODS

1891 students, from five Palestinian universities in the West Bank and Gaza Strip, completed a self-administered, web-based survey in 2014-2015. The questionnaire, which was based on the Global Adults Tobacco Survey (GATS), had questions on WTS and cigarette smoking patterns and socio-demographic and university-related characteristics. Binary logistic regression analyses were computed to investigate associated factors with WTS and cigarette smoking.

RESULTS

50.9% of the sample was women. The mean age was 20.1 ± 2.0. Overall, 30.0% of participants were current tobacco smokers and 33.4% reported ever smoking tobacco through a waterpipe. The prevalence of current WTS (24.4%) surpassed the prevalence of current cigarette smoking (18.0%), with a significantly higher prevalence among men compared to women. The gender gap for WTS (36.4% vs. 12.9%) was smaller than that for cigarette smoking (32.8% vs. 3.6%). Binary logistic regression models for the total sample (men and women) revealed that men were more likely to be current waterpipe and cigarette tobacco smokers compared to women (AOR = 4.20, 95% CI = 3.22-5.48, and AOR = 10.91, 95% CI = 7.25-16.42, respectively). Geographic area of residence, faculty of study and self-reported academic achievement were also associated with the likelihood of being current waterpipe and cigarette tobacco smokers.

CONCLUSION

A high prevalence of WTS was reported among our study sample, and it surpassed the prevalence of cigarette smoking. Interventions to curb the practice of tobacco smoking among Palestinian youth should be tailored differently to WTS and cigarette smoking, be gender-sensitive and specific and target the regional variation in the smoking behavior.

Shisha (waterpipe) smoking initiation among youth in Malaysia and global perspective: a scoping review (2006-2015)

OBJECTIVE

To explore the initiating factors of waterpipe tobacco smoking (WTS) among youth.

STUDY DESIGN

The analytic framework for this scoping review was performed using the methodology outlined by Arksey and O'Malley, which includes identification of the research question, study selection, charting the data, collating, summarizing and reporting the results that were primarily guided by the research question; 'what is known about the initiation of shisha smoking among youth?'

METHODS

Electronic databases such as Cochrane, MEDLINE and PsycINFO were used to search for relevant articles. Articles included were all in English and published within the year of 2006 to 2015. Inclusion criteria; i) age range of 10 to 29 years; ii) examined the reasons why youth started or tried WTS; iii) in full text. Therefore, 26 articles were included in this scoping review.

RESULTS

This review has identified and classified the initiating factors of WTS among youth in four subtopics: individual factors, interpersonal influences, cigarettes and alcohol use, and media influences. Individual factors and interpersonal influences played an important role in initiation factors of WTS among youth.

CONCLUSION

This study concludes that public health professionals within the Southeast Asia region need to promote innovative preventive measures through peer-to-peer led interventions that are also easily assessable on social media platforms. The public health messages need to address the misconceptions of risk associated to WTS use.

Conclusions

There is accumulating evidence about the association of waterpipe tobacco smoking with a growing number of health outcomes.

Waterpipe tobacco smoking and its human health impacts

Waterpipe tobacco smoking (WTS, also known as hookah, shisha, narghile, and many other names) involves passing tobacco smoke through water prior to inhalation by the consumer. As the number of waterpipe smokers is rising rapidly, there is growing concern over the use of WTS, particularly as there has been a widely held misconception that WTS is free from health hazards. In reality, it is associated with a variety of adverse health outcomes on both a short- and long-term basis. Hence, it is desirable to develop advanced techniques for surveillance, intervention, and regulatory/policy frameworks specific to the production and use of waterpipe tobacco. This review is written to survey the types and extent of pollutants released from its use and their potential health risks. A review of the present regulation guidelines is also included.

Waterpipe tobacco smoking: A new smoking epidemic among the young?

Waterpipe (hookah, narghile) tobacco smoking (WTS) is becoming prevalent worldwide and is one of the most popular forms of tobacco use among youth. WTS prevalence has increased dramatically among youth in the United States within the past decade. Misperceived as less harmful than cigarette smoking, WTS is associated with many of the same chronic health effects such as lung cancer, chronic obstructive pulmonary disease, cardiovascular disease, bronchitis, and asthma. Much of this risk is due to the fact that a single WTS session exposes users to large volumes of smoke that contain toxic chemicals such as carbon monoxide, cancer-causing polycyclic aromatic hydrocarbons, and volatile aldehydes. Unlike cigarette smoking, WTS poses unique risks of acute negative health outcomes including carbon monoxide poisoning and the spread of communicable diseases such as herpes and tuberculosis. Because waterpipe tobacco smoke contains the addictive chemical nicotine, youth who smoke tobacco from a waterpipe may be at risk for dependence. As a result, many youth may initiate WTS and continue to use despite negative health effects. Considering many of the potential negative health effects associated with WTS affect the pulmonary system, pulmonologists and primary care providers may treat patients who are waterpipe tobacco smokers and should be aware of the risk associated with WTS. The purpose of this review is to describe a waterpipe, the prevalence and correlates of WTS, the toxicants found in waterpipe tobacco smoke, the health effects of WTS, and implications for pulmonologists and other clinicians.
