Water pipe smoking among public versus private university students in Ankara, Turkey: an online survey.

BACKGROUND: Water pipe smoking has become a global public health problem as its popularity increased over time, especially among youth. The objective of our study was to estimate water pipe tobacco smoking prevalence and to assess socioeconomic factors associated with ever water pipe smoking by public and private university students in Ankara, Turkey. METHODS: This descriptive study was based on a survey conducted among public (n=2685) and private (n=2485) university students via an online questionnaire on demographics and water pipe consumption patterns. For every student in the sample, a socioeconomic status index was calculated using principal component analysis. Binary logistic regressions for the outcome variable of ever-using water pipe yielded estimates of adjusted odds ratios (aORs) for the associated factors such as the respondent's age, gender, university type, and socioeconomic status. RESULTS: The prevalence of ever use of water pipe was 69.1% (95% CI: 67.2-70.9%) among private and 59.1% (95% CI: 57.2-60.9%) among public university students. A substantial share of ever users were current users (25.5% in private versus 21.6% in public, p=0.008). On average, private university students had higher socioeconomic status than public university students (for example, access to a car (51.7% versus 35.8%, p=0.008), financial support from family (71.5% versus 65.1%, p<0.001)), also demonstrated by a higher socioeconomic status index. Being a private university student (aOR 1.57, 95% CI: 1.38-1.79), older (aORs 1.50 to 2.39, p<0.001), male (aOR 2.36, 95% CI:2.06-2.70), as well as having greater financial resources, such as having access to a car (aOR 1.24, 95% CI:1.07-1.42), or having income support from family (aOR 1.32, 95% CI:1.13-1.54), were associated with ever-using water pipe. A higher SES index was significantly associated with higher odds of ever using water pipe among both private (aOR 1.13, 95% CI:1.06,1.20) and public university (aOR 1.12, 95% CI:1.06,1.19) students. CONCLUSIONS: Water pipe smoking was common in both public and private universities; however, private university students had higher odds of ever using water pipe. There is an urgent need to implement evidence-based interventions, taking into account the socioeconomic status of young adults, to prevent them from water pipe smoking.

Prevalence and Predictors of Waterpipe Smoking Initiation and Progression Among Adolescents and Young Adults in Waves 1-4 (2013-2018) of the Population Assessment of Tobacco and Health (PATH) Study.

INTRODUCTION: Waterpipe tobacco (WPT) smoking has increased among the young population in the United States. This study assessed the extent and predictors of WPT smoking initiation and progression among US adolescents (12-17 years) and young adults (18-24 years) longitudinally. AIMS AND METHODS: We analyzed data from 4 waves (2013-2018) of the Population Assessment of Tobacco and Health (PATH) study comprising 10 692 respondents (adolescents = 5428 and young adults = 5264). Kaplan-Meier survival method estimated probabilities of WPT initiation and progression. Cox proportional hazards regression models delineated predictors of the outcomes. RESULTS: Between 2013 and 2018, 4.8% of adolescents initiated and 10.6% progressed WPT smoking. Among young adults, 18.5% initiated and 14.1% progressed WPT smoking during the same time interval. Predictors among adolescents included, WPT initiation: Hispanic ethnicity (adjusted odds ratio (aHR) = 1.75, 95% confidence interval (CI) = 1.23-2.49), lower harm perception (aHR = 2.89, 95% CI = 2.10-3.98), and other tobacco products use (aHR = 3.97, 95% CI = 2.73-5.78); WPT progression: illicit drug use (aHR = 4.60, 95% CI = 1.99-10.67). Predictors among young adults included, WPT initiation: non-Hispanic Black (aHR = 2.31, 95% CI = 1.78-3.00), Hispanic (aHR = 1.77, 95% CI = 1.34-2.33), lower harm perception (aHR = 2.77, 95% CI = 2.19-3.50), and other tobacco products use (aHR = 3.14, 95% CI = 2.25-4.38); WPT progression: non-Hispanic Black (aHR = 1.51 95% CI = 1.09-2.10), lower harm perception (aHR = 1.80, 95% CI = 1.41-2.30), and alcohol use (aHR = 1.61, 95% CI = 1.13-2.30). CONCLUSIONS: Results indicate a high prevalence of WPT initiation and progression among adolescents and young adults over time, with minority racial/ethnic groups being at greater risk for both. WPT-specific risk communication interventions (eg, educational campaigns and health warning labels) are warranted to limit WPT smoking among young people.

Trends of maternal waterpipe, cigarettes, and dual tobacco smoking in Jordan. A decade of lost opportunities.

BACKGROUND: Maternal tobacco use is a global public health problem. In the literature, the focus was mainly on cigarette smoking, minimally on waterpipe use, and totally ignored dual use among pregnant women. We estimated the prevalence of current maternal tobacco use by tobacco product (cigarette, waterpipe, and dual use) over a period of ten years (2007 to 2017), and examined the socio-demographic patterning of maternal tobacco use. METHODS: A secondary analysis of Jordan DHS four data waves was conducted for women who reported to be pregnant at the time of the survey. Current cigarette and waterpipe tobacco use were investigated. Prevalence estimates for cigarette-only, waterpipe-only, and dual use, as well as for cigarette, regardless of waterpipe, and waterpipe, regardless of cigarette, were reported. The effect of independent variables on cigarette smoking, waterpipe use, and dual use was assessed. Logistic regression models assessed the adjusted effects of socio-demographic variables on cigarette smoking, waterpipe use, and on dual use. For each outcome variable, a time-adjusted and a time-unadjusted logistic models were conducted. RESULTS: Over the last decade, the prevalence estimates of current cigarette-only smoking slightly decreased. The prevalence estimates of current waterpipe-only use exceeded those for cigarette-only after 2007 and showed a steady overall increase. Current dual use showed a continuous rise especially after 2009. Gradual increase in cigarette smoking (4.1%, in 2007, and 5.7% in 2017) and in waterpipe use (2.5% to 6.4%) were detected. Education showed an inverse relationship with cigarette and waterpipe smoking. Household wealth demonstrated a positive association with cigarette and waterpipe smoking. CONCLUSIONS: Tobacco use epidemic is expanding its roots among pregnant women in Jordan through not only waterpipe use but also dual cigarette-waterpipe smoking. Maternal and child services should consider tobacco counseling and cessation.

Transitions in hookah (Waterpipe) smoking by U.S. sexual minority adults between 2013 and 2015: the population assessment of tobacco and health study wave 1 and wave 2.

BACKGROUND: Tobacco smoking using a hookah (i.e., waterpipe) is a global epidemic. While evidence suggests that sexual minorities (SM) have higher odds of hookah use compared to heterosexuals, little is known about their hookah use patterns and transitions. We sought to examine transitions between hookah smoking and use of other tobacco and electronic (e-) products among SM adults aged 18 years of age and older versus their heterosexual counterparts. METHODS: We analyzed nationally representative data of ever and current hookah smokers from Wave 1 (2013-2014; ever use n = 1014 SM and n = 9462 heterosexuals; current use n = 144 SM and n = 910 heterosexuals) and Wave 2 (2014-2015; ever use n = 901 SM and n = 8049 heterosexuals; current use n = 117 SM and n = 602 heterosexuals) of the Population Assessment of Tobacco and Health Study. Comparisons between groups and gender subgroups within SM identity groups were determined with Rao-Scott chi-square tests and multivariable survey-weighted multinomial logistic regression models were estimated for transition patterns and initiation of electronic product use in Wave 2. RESULTS: Ever and current hookah smoking among SM adults (ever use Wave 1: 29% and Wave 2: 31%; current use Wave 1: 4% and Wave 2: 3%) was higher than heterosexuals (ever use Wave 1: 16% and Wave 2: 16%; current use Wave 1: 1% and Wave 2: 1%; both p < 0.0001). Among SM adults who reported hookah use at Wave 1, 46% quit hookah use at Wave 2; 39% continued hookah use and did not transition to other products while 36% of heterosexual adults quit hookah use at Wave 2 and 36% continued hookah use and did not transition to other products. Compared with heterosexuals, SM adults reported higher use of hookah plus e-products (Wave 2 usage increased by 65 and 83%, respectively). CONCLUSIONS: Compared to heterosexuals, in addition to higher rates of hookah smoking, higher percentages of SM adults transitioned to hookah plus e-product use between 2013 and 2015. Results have implications for stronger efforts to increase awareness of the harmful effects of hookah as well as vaping, specifically tailored among SM communities.

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.

Transitions in frequency of hookah smoking among youth and adults: findings from waves 1 and 2 of the Population Assessment of Tobacco and Health (PATH) study, 2013-15.

BACKGROUND AND AIMS: The prevalence of hookah smoking has increased in the United States since at least 2010, especially among youth and young adults. This study assessed self-reported reasons for hookah smoking cessation and transition to or maintenance of high-frequency hookah smoking among current hookah smokers. DESIGN: Separately analyzed data from the Population Assessment of Tobacco and Health (PATH) study, a longitudinal cohort study. Frequency of and reasons for hookah smoking were ascertained at wave 1 (2013-14); frequency of hookah smoking and past-year cessation were ascertained at wave 2 (2014-15). Weighted multivariable logistic and ordinal logistic regression models were fitted to predict hookah smoking cessation and frequency of hookah smoking at wave 2, respectively, accounting for demographic and behavioral risk factors, reasons for hookah smoking and frequency of hookah smoking at wave 1. SETTING: United States. PARTICIPANTS: A total of 693 youth and 4400 adult past-year hookah smokers. MEASUREMENTS: Self-reported tobacco-use patterns and associated health behaviors were measured via audio computer-assisted self-interviews (ACASI). FINDINGS: At wave 1, 5.9% of youth and 7.5% of adults were past-year hookah smokers. Among all age groups, the leading reasons for hookah smoking were enjoyment of socializing while smoking, the availability of appealing flavors and believing that it was less harmful than cigarette smoking. The odds of cessation were lower for adults who liked hookah flavors [adjusted odds ratio (aOR) = 0.40; 95% confidence interval (CI) = 0.26-0.62] compared with adults who did not like hookah flavors. The odds of transitioning to, or maintaining, monthly or more frequent hookah smoking at wave 2, compared with cessation or less than monthly smoking, were higher for adults who liked hookah flavors [adjusted proportional odds ratio (aPOR) = 2.10; 95% CI = 1.48-2.99 and enjoyed socializing while smoking hookah (aPOR = 1.82; 95% CI =1.13-2.94) compared with adults who did not like hookah flavors or socializing. CONCLUSION: The availability of appealing flavors, affordability and socialization while smoking hookah in the United States are associated with reduced likelihood of cessation and increased likelihood of high-frequency hookah smoking.

Factors affecting hookah tobacco smoking among females in the Islamic Republic of Iran: a qualitative study.

BACKGROUND: The prevalence of hookah smoking in the Islamic Republic of Iran is increasing among females, especially in the southern cities. AIMS: The aim of this study was to investigate the factors influencing hookah tobacco smoking among females in the Islamic Republic of Iran. METHODS: In this qualitative study, 52 females who use hookah were selected (25-71 years old) from the cities of Evaz and Gerash and were interviewed. The participants were selected using purposive sampling and the data were gathered using semi-structured interviews. Data analysis was performed using the conventional approach of qualitative content analysis. RESULTS: Most participants were aged between 25 and 35 years old and 55.8% were married. Three main themes were identified from the qualitative data including: personal factors, family factors and social factors. CONCLUSIONS: The findings of this study indicate that the reasons for hookah smoking were based on complex interactions between individual, family, and social factors. In order to successfully reduce hookah smoking in females it is necessary to consider an approach that uses these social factors.

Hookah use patterns, social influence and associated other substance use among a sample of New York City public university students.

BACKGROUND: Most hookah use studies have not included racial and ethnic minorities which limits our understanding of its use among these growing populations. This study aimed to investigate the individual characteristics of hookah use patterns and associated risk behaviors among an ethnically diverse sample of college students. METHODS: A cross-sectional survey of 2460 students (aged 18-25) was conducted in 2015, and data was analyzed in 2017. Descriptive statistics were used to present the sociodemographic characteristics, hookah use-related behavior, and binge drinking and marijuana use according to the current hookah use group, including never, exclusive, dual/poly hookah use. Multivariate logistic regression was conducted to examine how hookah related behavior and other risk behaviors varied by sociodemographics and hookah use patterns. RESULTS: Among current hookah users (n = 312), 70% were exclusive hookah users and 30% were dual/poly hookah users. There were no statistically significant differences in sociodemographic characteristics except for race/ethnicity (p < 0.05). Almost half (44%) of the exclusive hookah users reported having at least five friends who also used hookah, compared to 30% in the dual/poly use group. Exclusive users were less likely to report past year binge drinking (17%) and past year marijuana use (25%) compared to those in the dual/poly use group (44 and 48% respectively); p < 0.001. CONCLUSIONS: The socialization aspects of hookah smoking seem to be associated with its use patterns. Our study calls for multicomponent interventions designed to target poly tobacco use as well as other substance use that appears to be relatively common among hookah users.

Determinants of hookah smoking among men in the coffee houses: an application of socio-ecological approach.

BACKGROUND: Tobacco smoking is the second leading cause of death and is closely linked to fatal diseases. Hookah Smoking (HS) is a traditional way to smoke tobacco, especially in the Eastern Mediterranean region that is constantly rising around the world. This study aimed to evaluate the different levels of personal, interpersonal and social HS in Iranian urban men and determine the most important predictors of the levels through applying the socio-ecological approach (SEA). METHODS: This study was conducted in the coffee houses of Hashtrud and Qarah Aghaj counties in East Azerbaijan, Iran. Data collection was conducted from the entire coffee house (n = 18) from April to June 2017. Systematic sampling was employed to recruit 266 men in the coffee house. A valid and reliable instrument was used to investigate the frequency of HS and its determinants based on SEA. The SEA consists of three levels: personal (age, education, employment, income, and perceived severity and sensitivity), interpersonal (perceived reward), and social level (social support) intended to assess HS determinants. Hierarchical regression was used to determine the predictive value of SEA levels and frequency of HS. RESULTS: The mean age of daily hookah smokers (once per day and more than once per day) were (26.8) significantly lower than those (30.4) smokes weekly (once a week or more than once a week). The hierarchical logistic regression model showed that in the first step individual variables significantly predict 25.1% HS. In the second and third level interpersonal and social levels of SEA explained HS 30.1 and 30.8%, respectively. CONCLUSION: This study found that age, income, education, and perceived reward were all important factors influencing HS among men youth. Application of SEA to determine the factors associated with HS could contribute in the development of a holistic prevention program.

Prevalence of drug use, alcohol consumption, cigarette smoking and measure of socioeconomic-related inequalities of drug use among Iranian people: findings from a national survey.

BACKGROUND: Drug use can lead to several psychological, medical and social complications. The current study aimed to measure and decomposes socioeconomic-related inequalities in drug use among adults in Iran. METHODS: This was a cross-sectional study The PERSIAN Cohort is the largest and most important cohort among 18 distinct areas of Iran. This study was conducted on 130,570 adults 35 years and older. A structured questionnaire was applied to collect data. The concentration index (C) was used to quantify and decompose socioeconomic inequalities in drug use. RESULTS: The prevalence experience of drug use was 11.9%. The estimated C for drug use was - 0.021. The corresponding value of the C for women and men were - 0.171 and - 0.134, respectively. The negative values of the C suggest that drug use is more concentrated among the population with low socioeconomic status in Iran (p < 0.001). For women, socioeconomic status (SES) (26.37%), province residence (- 22.38%) and age (9.76%) had the most significant contribution to socioeconomic inequality in drug use, respectively. For men, SES (80.04%), smoking (32.04%) and alcohol consumption (- 12.37%) were the main contributors to socioeconomic inequality in drug use. CONCLUSIONS: Our study indicated that drug use prevention programs in Iran should focus on socioeconomically disadvantaged population. Our finding could be useful for health policy maker to design and implement effective preventative programs to protect Iranian population against the drug use.

Factors related to the use of hookah among medical students. / Fatores relacionados ao consumo do narguilé entre estudantes de medicina.

OBJECTIVE: This study evaluated the factors related to the use of hookah among medical students, the level of knowledge about the involved harms, and their relationship with the use and intention to stop using it. METHODS: Students of the 1st and 6th year of medical school were evaluated. A multivariate logistic regression model was used to evaluate the association between the outcome (use of hookah in the last 30 days) and demographic, subjective psychosocial data and level of knowledge about the harms of hookah use. RESULTS: The experimentation rate of hookah and current use was high (59.6% and 27.7%, respectively), with no difference between the 1st and 6th year groups (p=0.70). The 6th grade students were more knowledgeable about the harm of using hookah when compared to the 1st year students (p <0.0001), and there was no association between the use of hookah in the last 30 days and the knowledge about its harms. Cigarette smoking and the use of alcoholic beverages were associated with the use of hookah in the last 30 days, with unadjusted Odds Ratio (OR) of 11.3; 95% CI 4.62-27.7; p <0.0001 and OR 8.74; 95% CI 3.78-20.2; p <0.0001; respectively. CONCLUSION: There is a high experimentation, current use of hookah and cigarettes among medical students. Sixth year students are more knowledgeable about the harms involved. There was no association between the use of hookah in the last 30 days and the knowledge about its harms. Smoking and the use of alcoholic beverages are independent predictors of use of hookah.

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.

Waterpipe Tobacco Smoking among University Students in Three Eastern Mediterranean Countries: Patterns, Place, and Price.

Background: The objective of this study was to examine waterpipe tobacco smoking patterns, places of smoking, and prices paid among university students in the Eastern Mediterranean Region. Methods: A cross-sectional online survey was administered to a convenience sample of university students in three countries. Participants were young adults (18-29 years) who were ever waterpipe smokers, from Egypt (n = 728), Jordan (n = 790), and Palestine (n = 722). Measures included past-30-day waterpipe smoking, frequency, intensity, place of smoking, and prices paid per waterpipe smoking session and for packaged waterpipe tobacco. Logistic regression models evaluated the factors associated with past-30-day waterpipe smoking. Results: Past-30-day waterpipe smoking (prevalence) was observed among 60.7%, 67.7% and 63.1% of students from Egypt, Jordan, and Palestine, respectively. Among past-30-day smokers, past-5-day waterpipe smoking (frequency) was observed among 28.9%, 51.5%, and 48.6% of participants, respectively. Smoking in a café was highest among participants from Egypt (74.0%), followed by those from Palestine (44.8%), and Jordan (43.0%). Mean price paid per session was USD 0.99 (Egypt), USD 8.07 (Jordan), USD 6.05 (Palestine). The corresponding mean prices per packet were USD 0.86, USD 4.96, and USD 5.55, respectively. Predictors of past-30-day waterpipe smoking included younger age of initiation, male gender, employment, and smoking waterpipe alone. Conclusions: This study contributes to our understanding of waterpipe smoking patterns, places of smoking, and prices paid among young adults in a region with alarmingly high smoking rates. Understanding waterpipe smoking behaviors can inform the design of policy and educational interventions to curb its rising threat.

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

BACKGROUND: Waterpipe tobacco smoking (WTS or 'hookah') is common among adolescents and college students in the USA. However, there has not yet been a large-scale, nationally representative study independently examining WTS among young adults who are not in college. OBJECTIVE: This study sought to examine associations between attitudes, normative beliefs, certain socio-demographic factors and current WTS among young adults not in college and compare them to young adults in college. METHODS: A total of 3131 US adults ages 18-30 completed an online survey about WTS behaviour, attitudes, normative beliefs and relevant socio-demographic factors. Multivariable logistic regression was used to examine independent associations between these variables and current WTS stratified by student status. RESULTS: Ever WTS was reported by 29% of young adults not in college and by 35% of those in college, and current use rates were 3 and 7%, respectively. Multivariable models demonstrated that positive attitudes and perceived peer acceptability of WTS were significantly associated with increased current WTS for both young adults not in college [adjusted odds ratio (AOR) = 2.72; 95% CI: 2.00-3.71 and AOR = 2.02; 95% CI: 1.50-2.71, respectively] and young adults in college (AOR = 3.37; 95% CI: 2.48-4.58 and AOR = 2.05; 95% CI: 1.49-2.83, respectively). The magnitude of these associations was not significantly different when comparing individuals in college and not in college. CONCLUSIONS: Among young adults, WTS is common in non-college-based populations as well as in college-based populations. Therefore, prevention programming should extend to all young adults, not only to those in college.

Factors associated with the use of waterpipe and other tobacco products among students, Brazil, 2015. / Fatores associados ao uso de narguilé e outros produtos do tabaco entre escolares, Brasil, 2015.

OBJECTIVE: To identify the frequency and factors associated with the use of waterpipe and other tobacco products among Brazilian students. METHODS: This is a cross-sectional study based on data from the National Adolescent Student Health Survey. The sample consisted of 9th-grade students from elementary school. We conducted a descriptive analysis of the use of tobacco products in 2012 and 2015. To explore the relationship between the use of other tobacco products and factors such as sociodemographic characteristics, family, mental health, and life habits, we calculated the adjusted odds ratio. RESULTS: The use of other tobacco products increased from 4.8% (95%CI 4.6 - 5.0) in 2012 to 6.1% (95%CI 5.7 - 6.4) in 2015, with a higher proportion among boys. Waterpipe was the most commonly used product in 2015 (71.6%; 95%CI 68.8 - 74.2), especially among girls. Factors positively associated with the use of other tobacco products were: attending private school, living with father/mother, working, not having friends, suffering domestic violence, skipping classes, consuming cigarettes and alcohol, experimenting drug, having had sex, having smoker parents or guardians, and seeing people smoking. The protective factors were: female gender, increasing age, multiracial or indigenous people, having meals with a guardian, family supervision, and practicing physical activity. CONCLUSION: The use of other tobacco products was high and has been increasing in recent years, particularly waterpipe. It is important to raise awareness of the risks and monitor the use of these products, as well as improve public policies of tobacco control in the country.

OBJETIVO: Identificar a frequência e os fatores associados ao uso de narguilé e outros produtos do tabaco entre os escolares brasileiros. MÉTODOS: Estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar. A amostra foi composta por alunos do 9º ano do Ensino Fundamental. Foi realizada análise descritiva do uso de produtos do tabaco em 2012 e 2015. Para explorar a relação de fatores como características sociodemográficas, familiares, saúde mental e hábitos de vida com o uso de outros produtos do tabaco, foram calculados odds ratio ajustados. RESULTADOS: O uso de outros produtos do tabaco aumentou de 4,8% (IC95% 4,6 - 5,0), em 2012, para 6,1% (IC95% 5,7 - 6,4), em 2015, com maior proporção em meninos. O narguilé foi o produto mais usado em 2015 (71,6%; IC95% 68,8 - 74,2), sendo mais frequente em meninas. Foram positivamente associados ao uso de outros produtos do tabaco: escola privada, morar com pai/mãe, trabalhar, não ter amigos, sofrer violência familiar, faltar às aulas, fazer uso de cigarros e álcool, ter experimentado drogas, já ter tido relação sexual, ter pais ou responsáveis fumantes e presenciar pessoas fumando. Os fatores de proteção foram: sexo feminino, incremento da idade, cor da pele parda ou indígena, fazer refeições com responsável, ter supervisão familiar e praticar atividade física. CONCLUSÃO: Conclui-se que o uso de outros produtos do tabaco foi elevado, com aumento nos últimos anos, destacando-se o narguilé. Torna-se importante a conscientização dos riscos e a vigilância do uso desses produtos, bem como o avanço das políticas públicas de controle do tabagismo no país.

The Gap of Cigarette and Hookah Smoking Between Socioeconomic Groups in Iran: Effect of Inequalities on Socioeconomic Position.

BACKGROUND: Hookah and cigarette smoking have adverse effects on individuals' health and therefore place a great burden on public health. The aim of this study was to measure inequalities in socioeconomic position to determine contributing factors on cigarette and hookah smoking in Iran. METHODS: In this study, secondary analysis of the Iran's sixth national Surveillance of Risk Factors of Non-Communicable Diseases (SuRFNCD-2011) was conducted for 10,572 individuals aged 15 to 70 years old. Subjects were categorized into three groups according to their socioeconomic status (low, middle and high) in order to assess their inequalities using principal component analysis. At the end, the gap between the low and high socioeconomic groups was decomposed using Blinder-Oaxaca decomposition technique. RESULTS: The prevalence of cigarette and hookah smoking in high, middle, and low socioeconomic groups was 11.8%, 13.2%, and 13.1% (P=0.158), and 2.6%, 3.3% and 4.3%, (P<0.001), respectively. Blinder-Oaxaca decomposition technique showed a lower prevalence of hookah smoking in high socioeconomic group compared to low socioeconomic group (P<0.001). The gap between the two mentioned groups was measured to be 1.7%. However, this gap for cigarette smoking (1.5%) was not significant (P=0.093). CONCLUSION: The finding indicates the importance of socioeconomic status in hookah smoking. After decomposition of the gap between the 2 socioeconomic groups, age, gender and education level were reported to be the major contributors to the differences observed between the 2 groups.

Multiple tobacco use among young adult waterpipe smokers in Egypt.

BACKGROUND: The use of multiple tobacco products is an emerging trend. Studies on multiple use among waterpipe smokers are limited. OBJECTIVES: We aimed to estimate the proportion of other tobacco products used by current adult waterpipe smokers in Egypt and identify the determinants of multiple tobacco product use. METHODS: Population-based surveys were conducted using interview questionnaires during 2015-2017 in urban Cairo and rural Menoufia. Participants aged 18 years and older were selected using purposive quota non-random sampling. The total sample included 2 014 participants. We analysed the data on 1 490 current waterpipe smokers. Variables recorded included: tobacco use, health beliefs, waterpipe smoking behaviour, sociodemographic characteristics, and perceived effectiveness of pictorial health warnings on waterpipe tobacco packs. Current waterpipe smokers were classified as waterpipe-only users and multiple tobacco product users. RESULTS: Almost half (47.9%) of the current waterpipe smokers used multiple tobacco products; 93.4% were dual users and 6.6% poly-users. The other tobacco products used were cigarettes (86.4%), electronic nicotine delivery systems (ENDS) (7.0%) or both (6.6%). Multiple users were more likely to be younger than waterpipe-only users. Young adult female waterpipe smokers used ENDS 12 times more than young adult males (48.8% versus 4.1% respectively). Non-daily waterpipe smoking, usually smoking at cafes, higher education and knowledge of pictorial health warnings were independent predictors of multiple tobacco product use. CONCLUSION: Multiple tobacco product use was common among current waterpipe smokers in our study. Interventions to tackle non-cigarette and multiple tobacco use, especially in young adults, are urgently needed.

Assessment of matrix metalloproteinase-8 and -9 levels in the peri-implant sulcular fluid among waterpipe (narghile) smokers and never-smokers with peri-implantitis.

OBJECTIVES: It is hypothesized that levels of matrix metalloproteinase (MMP)-8 and MMP-9 are significantly higher in the peri-implant sulcular fluid (PISF) of waterpipe-smokers (WS) compared with never-smokers with peri-implantitis. The aim of the present convenience sample case-control study was to compare the levels of MMP-8 and MMP-9 in the PISF of WS and never-smokers with peri-implantitis. MATERIAL AND METHODS: Individuals smoking waterpipe (Group 1) and never-smokers (Group 2) were included. Demographic data was collected using a questionnaire. Peri-implant probing depth (PPD) was measured and crestal bone loss (CBL) was measured on digital bitewing radiographs. PISF samples were collected using paper strips and the collected PISF volume was determined. Levels of MMP-8 and MMP-9 were measured using enzyme-linked immunosorbent assay. Study sample-size was estimated and statistical analysis was performed. p values < .05 were considered statistically significant. RESULTS: Sixty-six individuals (33 individuals in Group 1 and 33 in Group 2) were included. In Groups 1 and 2, 41 and 44 implants, respectively were placed. The mean total PPD (p < .001) and peri-implant CBL (p < .001) was statistically significantly higher around implants affected by peri-implantitis in Group 1 compared with Group 2. The PISF volume (p < .05) collected and levels of MMP-8 (p < .01) and MMP-9 (p < .01) were statistically significantly higher among individuals in Group 1 compared with Group 2. CONCLUSION: PISF levels of MMP-8 and MMP-9 are significantly higher among WS compared with never-smokers with peri-implantitis.

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

Introduction: Hookah tobacco smoking has increased in the United States. However, information on hookah use frequency and other characteristics of hookah use is limited. Methods: Investigators analyzed data from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative, longitudinal cohort study of US youth and adults. Our analysis draws on baseline data from adult (ages ≥18 years) ever (N = 10 624) and past year (n = 3947) hookah users. Bivariate and regression analyses were conducted to identify associations between demographics, use characteristics, and hookah use frequency. Results: Overall, 16.4% of adults reported ever smoking tobacco from a hookah. Of those, 31.9% reported smoking hookah within the past year. Among 3947 past-year hookah tobacco smokers, 10.7% were daily/weekly users, 13.7% were monthly users, 42.1% smoked every couple of months, and 33.5% smoked about once a year. Among daily/weekly hookah users, 66% were young adults (ages 18-24 years). When comparing daily/weekly hookah users to those who smoked every couple of months, more frequent hookah use was associated with younger age, male gender, a greater number of times the hookah is refilled during a session, fewer people sharing, and hookah ownership. Conclusion: Although there were few demographic differences between daily/weekly users and less frequent hookah tobacco smokers, some notable differences in use behaviors exist among use frequency groups. Unlike other tobacco products, hookah is often smoked communally, over an extended time period. A detailed understanding of hookah user characteristics and experiences could inform hookah-specific measures, messaging, and regulations. Implications: To our knowledge, this is one of the first studies to characterize hookah use frequency, session length, and other hookah use experiences using a nationally representative sample of US adult hookah smokers. Understanding characteristics of hookah tobacco smokers, their use experiences, and patterns of hookah use frequency would be useful in assessing risks for hookah tobacco dependence at the population level. Additionally, identifying variation in use behaviors of hookah tobacco smokers could be used to inform the development of strategies to reduce and prevent hookah tobacco use, such as tobacco regulations or public education efforts, particularly among young adults.
