The relationship of waterpipe use with cigarette smoking susceptibility and nicotine dependence: A cross-sectional study among Hong Kong adolescents

Association between waterpipe use and susceptibility to cigarette smoking among adolescents and young adults who never smoked: A systematic review and meta-analysis

INTRODUCTION

Several factors associated with susceptibility to cigarette smoking have been identified, yet there is little evidence on the possible effects of waterpipe use. With this systematic review and meta-analysis, we aimed to investigate the relationship between waterpipe use and cigarette smoking susceptibility among adolescents and young adults who never smoked.

METHODS

Eligible studies were searched in PubMed, Springer Link, ScienceDirect and Cochrane Library up to August 2022. The pooled odds ratio (OR) and 95% confidence intervals (CI) of cigarette smoking susceptibility with waterpipe use were estimated using a random-effects model. Publication bias was assessed by Egger's regression asymmetry test and Begg's rank correlation test with Begg's funnel plot.

RESULTS

A total of 59710 participants, including 3559 waterpipe users from six studies, were identified in this analysis. Results showed that the odds of susceptibility to cigarette smoking were nearly two times (OR=1.90; 95% CI: 1.59-2.26) greater for never smoker adolescents and young adults who used waterpipe tobacco, compared to those who were never users. In subgroup analyses, the pooled OR was 2.19 (95% CI: 1.52-3.14) and 1.70 (95% CI: 1.51-1.92) for current and ever use of waterpipe, while the pooled OR was 1.99 (95% CI: 1.35-2.95) and 1.87 (95% CI: 1.45-2.39) in Arab and non-Arab nations, respectively.

CONCLUSIONS

Our findings suggest that waterpipe use was associated with greater odds of susceptibility to cigarette smoking among adolescents and young adults who never smoked. Tailored public health policies and regulations on waterpipe smoking may help to protect youth never smokers from initiation of cigarette smoking.

The effect of exposure to tobacco smoking-related media messages on youths' smoking behavior in Jordan: A longitudinal, school-based study

Only a few studies investigated the link between tobacco smoking-related media and youth smoking in the Eastern Mediterranean Region (EMR). This study aimed to assess the influence of both promotional and control messages on cigarette smoking behavior among young Jordanian students. Generalized Linear Mixed Models were analyzed using data from the Irbid Longitudinal Smoking Study that followed a random sample of 2174 students (2008-2011). We examined the associations of media messaging with smoking behavior, as well as intention-to-quit smoking, and intention-to-start smoking, among young adolescents. At baseline, 12.2% and 43.7% of students were exposed to only pro-smoking or only anti-smoking messages, while 41.8% were equally exposed to both. Exposure to anti-smoking messages was associated with lower odds of ever smoking at baseline among girls (AOR = 0.4; 95% CI: 0.2, 0.8). Boys who were exposed to anti-smoking messages were more likely to report an intention to quit, with borderline significance (AOR = 2.0; 95% CI: 0.9, 4.1). The cumulative exposure to anti-smoking messages over time was associated with lower odds of intention to smoke among girls (AOR = 0.5; 95% CI: 0.3, 0.9) but with higher odds among boys (AOR = 1.8; 95% CI: 1.0, 3.1). In both sexes, media messaging was not associated with progression of the smoking habit. In conclusion, this comprehensive analysis of both pro- and anti-smoking messages advances our understanding of their role in influencing youths' smoking behaviors, and could guide the development of evidence-based interventions to address adolescent tobacco smoking in Jordan and the EMR.

E8-LWDS: Factorial Structure and Psychometric Properties of the Lebanese Waterpipe Dependence Scale-11 in 1490 Egyptian Waterpipe Tobacco Smokers-A Critical Approach

INTRODUCTION

There is no universal scale for assessing waterpipe tobacco (WT) dependence. We examined the factorial structure and psychometric properties of the Waterpipe Dependence Scale-11 (LWDS-11) among Egyptian WT smokers.

METHODS

We administered the LWDS-11 during face-interview questionnaires in two cross-sectional surveys among 1490 current WT smokers recruited via purposive quota sampling. Exploratory factor analysis was performed on half of the sample. Confirmatory factor analysis of the resulting model was done using structural equation modelling on the other half. Scale reliability was examined. We assessed convergent construct validity using regression models to examine the association between the adapted dependence scale and factors conceptually expected to be associated with WT dependence.

RESULTS

Exploratory factor analysis of the scale yielded eight items (E8-LWDS) supporting a three-factor structure: physical dependence (three items); psychological dependence (three items); and psychological craving (two items). Cronbach's α were 0.635 for the total scale and 0.823, 0.654, and 0.785 for the three subscales. E8-LWDS was confirmed to have good model fit (comparative fit index = 0.995; root mean squared error of approximation = 0.027). E8-LWDS was independently associated with daily WT smoking, rural residence, being a skilled worker, non-exclusive WTS, smoking ≥ eight WT hagars/day, and measures of perceived behavioral control (self-reported addiction to WT, perceived ability to quit, and previous quit attempts).

CONCLUSION

E8-LWDS showed adequate psychometric properties among this sample of Egyptian current WT smokers, which makes it appropriate for use by researchers and practitioners. Adding items related to perceived behavioral control might enhance the scale robustness.

Polytobacco product use among current cigarette smokers in Hong Kong, China: results from population surveys (2015-17)

BACKGROUND

Polytobacco product use is increasingly popular, but little is known about the prevalence, trend, and factors of such use particularly in non-western countries.

METHOD

A representative sample of 1139 current cigarette smokers aged 15+ (84.1% male) were telephone interviewed in Tobacco Control Policy-related Surveys in 2015-2017. Information collected included poly-tobacco use (PTU), smoking and socio-demographic characteristics. Associations of current PTU with related factors were analyzed using logistic regression with adjustment for confounders. Prevalence was weighted by age and sex of current cigarette users in the general population.

RESULTS

Eighty-four point one percent (95% CI 81.4-86.6%) were exclusive cigarette smokers. Fifteen point nine percent (13.4-18.6%) were current polytobacco product users, 12.3% (10.2-14.8%) used one tobacco product and 2.52% (1.59-3.97%) used two tobacco products in addition to cigarette. Cigarette use with cigar was more common (6.28%, 4.75-8.27%), and the least used product with cigarette was e-cigarette (1.05%, 0.44-2.50%). The changes in overall prevalence of PTU by number of products use varied in 3 years. Current PTU was associated with being male (AOR 2.01, 95% CI 1.12-3.61), younger age (AORs range from 1.34-4.65, P for trend < .001) and less ready to quit (2.08, 1.09-3.97).

CONCLUSIONS

Prevalence of PTU increased slowly by year, one tobacco product use with cigarette was more common. The most used tobacco product with cigarette was cigar. Being male, younger and less ready to quit were associated with current PTU.

Waterpipe smoking among university students in Hong Kong: a cross-sectional study

BACKGROUND

Waterpipe smoking has gained global popularity in recent years, especially among young people. However, there is a lack of empirical investigation into waterpipe smoking in East Asia. This study aimed to investigate the demographical and psycho-social characteristics and patterns of waterpipe smoking (WPS) among university students in Hong Kong.

METHODS

A cross-sectional survey was conducted via online questionnaires administered to 1288 Hong Kong university students (mean age: 22.4 [SD = 3.8]). Logistic regressions were used to compute adjusted odd ratios (aOR) for waterpipe ever-smoking in relation to respondents' characteristics. Moreover, multinomial logistic regression yielded adjusted RR (aRR) for four different smoking status (i.e., never, waterpipe-only, cigarette-only, and dual smoking) regarding the characteristics.

RESULTS

23.8% of participants reported having ever smoked a waterpipe (vs. cigarette ever-smoking: 21.1%). Factors including being female (aOR:1.57; 95% CI: 1.22-2.02), older age (≥24 years: 4.17; 1.35-12.93), frequent alcohol consumption (>monthly: 26.02; 10.91-62.09), and higher sensation-seeking behaviours (high level: 2.98;1.46-6.08) were associated with waterpipe ever-smokers. The study also identified that demographical and psycho-social characteristics were variably associated with students' smoking status. Particularly, more frequent alcohol consumption was most significantly associated with waterpipe-only smoking (aRR:45.73; 95% CI:11.44-182.73) (vs. cigarette-only smoking: 3.01; 1.76-5.14).

CONCLUSIONS

WPS is the most common form of tobacco smoking among university students in Hong Kong, and characteristics unique to the population were identified. There is no legislation of relevant policies on WPS despite its concerning significance in public health among young people, therefore immediate action to monitor and control WPS is needed in Hong Kong.

Effect of waterpipe dependence on risk motives, attitudes and other health-related risky behaviors in Lebanese university students

Explore whether waterpipe dependence in young Lebanese adults would have any effect on modifying the association between risk conception, attitude, and other risky behaviors. A cross-sectional study was carried out using a proportionate cluster sample of Lebanese university students (3384 students). Waterpipe dependence was associated with higher association of alcohol dependence and cigarette dependence by 76.7% and higher excitement for dangerous behaviors by 7.1%. It was significantly associated with increased association of cigarette dependence and alcohol dependence by 66.8%, with the thinking of a behavior of being not dangerous by 239%, with having motives for risky behaviors by 74.1%, with ever having unsafe sex by 111.74%, and between having motives for risky behaviors and ever having unsafe sex by 61.95%. Waterpipe dependence was associated with higher motives, excitement, and perception of risk and risky behaviors, namely cigarette dependence, alcohol dependence, and unsafe sex. Moreover, it was associated with higher risky behavior interdependence.

Adolescent Smoking in Hong Kong: Prevalence, Psychosocial Correlates, and Prevention

Preventing adolescent smoking is important as smoking is typically initiated by young people. This article reviews the prevalence, psychosocial correlates, and prevention of smoking in Hong Kong adolescents. The past 30-day smoking prevalence in adolescents decreased from 9.6% in 2003 to 2.5% in 2017. Tobacco advertisements, parental and best friends smoking, nonintact families, poor family relationships, lower socioeconomic status, being a new immigrant, poor knowledge of smoking-related harm, positive attitudes toward smoking, overestimation of peer smoking, and depressive symptoms were positively associated with smoking outcomes, whereas positive youth development, authoritative mother and permissive father, family functioning, school competence, and stronger tobacco industry denormalization beliefs were protective against smoking. Along with tobacco tax increase, ban on tobacco advertisements, smoke-free law and pictorial warnings, educational efforts through theater performances, social norms campaigns, and positive adolescent training programs have been conducted to prevent adolescent smoking. To achieve the ultimate goal of tobacco endgame, further tax increase, plain packaging, banning point-of-sale display of tobacco products, smoke-free area extension, and raising minimum age of purchase should be implemented. The government proposed law to ban e-cigarettes, and heated tobacco products should be passed soon to protect children and adolescents from using these products.

Epidemiology and Adverse Consequences of Hookah/Waterpipe Use: A Systematic Review

Hookah smoking is becoming a popular trend globally. Waterpipe smoking is the second most prevalent form of alternate tobacco products. The rapid increase in hookah use is because of the misconception prevalent in society that hookah smoking is less harmful than cigarette smoking. Smoking ban policies had given impetus of switching from cigarette smoking to alternate tobacco products like waterpipe. Hookah users regard hookah to be more socially acceptable, less stigmatizing with flavors and to alleviate cigarette craving symptoms. Newer basic science research on animal models and human cells has shown consistently mutagenic, oxidative, and inflammatory changes that could cause possible health effects of premalignant oral lesion and chronic diseases like atherosclerosis and chronic obstructive pulmonary disease. Studies on the chemistry of waterpipe smoke had shown alarming results with the smoke containing seven carcinogens, 39 central nervous system depressants, and 31 respiratory irritants. Enormous data exist showing waterpipe smoking causing various health effects. Hookah smoking effects on cardiovascular disease is additive with hookah containing a significant amount of nicotine, tar, and heavy metals causing both acute and chronic effects on the cardiovascular system. These effects include increased heart rate, blood pressure, prevalence of coronary heart disease, heart failure, ST-segment elevation myocardial ischemia, recurrent ischemia, and worse outcomes including mortality related to these diseases. The objectives of the review are to assess the factor associated with the increasing use of hookah, its health effects, options for hookah smoking cessation, and public health policy initiatives to mitigate waterpipe use.

Bidirectional associations of e-cigarette, conventional cigarette and waterpipe experimentation among adolescents: A cross-lagged model

PURPOSE

With an increasingly diverse tobacco product market, it is imperative to understand the trajectories of product experimentation in order to design effective prevention programs. This study aims to explore the bidirectional associations of conventional cigarette, e-cigarette and waterpipe experimentation in a large adolescent sample.

METHODS

Longitudinal assessment of conventional cigarette, e-cigarette and waterpipe use initiation was conducted in a school-based cohort of 1369 9th graders (mean age=14.88 SD=0.48 at baseline) during fall 2014 and reassessed 6-months later using online self-reported questionnaires. Autoregressive cross-lagged analysis within structural equation modeling framework was performed to simultaneously estimate the initiation of these products over a six-month period, controlling for age, gender, and participation in an intervention program to reduce conventional cigarette initiation.

RESULTS

Tobacco product lifetime use was prevalent at baseline in the sample: conventional cigarettes (48.4%), e-cigarettes (35.8%), and waterpipe (20.8%). At six-month follow-up, trying conventional cigarettes predicted trying e-cigarette (adjusted odds ratio (AOR)=3.78, CI95%: 2.66-5.37) and trying waterpipe (AOR=2.82, CI95%: 2.00-3.97). Trying e-cigarette predicted trying conventional cigarette (AOR=3.57, CI95%: 1.96-6.49) and trying waterpipe (AOR=1.51, CI95%: 1.07-2.14). Although trying waterpipe predicted trying e-cigarette at follow-up (AOR=2.10, CI95%: 1.30-3.40), its use did not predict trying conventional cigarette (AOR=0.55, CI95%: 0.24-1.30).

CONCLUSIONS

The high rates of poly-tobacco use and the bidirectionality of tobacco product experimentation demands comprehensive tobacco control and prevention programs that address the increasingly diverse tobacco product market targeting adolescents.

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

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

Susceptibility to tobacco product use among youth in wave 1 of the population Assessment of tobacco and health (PATH) study

The purpose of this study was to investigate susceptibility and ever use of tobacco products among adolescents and young adults in the US. Cross-sectional analysis of Wave 1(2013-2014) adolescent (12-17year-olds; n=13,651) and young adult (18-24year-olds; n=9112) data from the nationally-representative Population Assessment of Tobacco and Health (PATH) Study was conducted. At 12years, 5% were ever tobacco users and 36% were susceptible to use. Seventy percent were susceptible at age 17years, and the same proportion were ever users at age 22years. Susceptibility levels were comparable for cigarettes and e-cigarette (28.6% and 27.4%, respectively), followed by hookah (22.0%), pipes (17.5%), cigars (15.2%), and smokeless tobacco (9.7%). Non-Hispanic (NH) Black (Adjusted Odds Ratio [ORadj]=1.36; 95% Confidence Limit [CL], 1.18-1.56) and Hispanic (ORadj=1.34: 95% CL,1.19-1.49) adolescent never- users were more likely to be susceptible to future use of a tobacco product than NH Whites. Susceptibility was higher with age (15-17yrs. vs 12-14yrs.: ORadj=1.69; 95% CL, 1.55-1.85) and parental education (college graduates vs less than HS education: ORadj=1.22, 95% CL, 1.08-1.39). Compared to exclusive users of hookah, cigars, or smokeless products, larger proportions of exclusive e-cigarette ever users were also susceptible to cigarette use. Among adolescents, lower levels of ever use of tobacco products are often counterbalanced by higher levels of susceptibility for future use, which may suggest delayed initiation in some groups. Ever users of a given tobacco product were more susceptible to use other tobacco products, putting them at risk for future multiple tobacco product use.
