Waterpipe is also increasingly becoming the first tobacco product that young people try. Given the limited access to and limited portability of waterpipes, waterpipe smokers who become more nicotine dependent over time may be more likely to turn to cigarettes. This study examined the relationship between waterpipe tobacco smoking and susceptibility to cigarette smoking among young adults in the United States. METHODS: Using data from the 2012-2013 National Adult Tobacco Survey, a nationally representative sample of US adults, we reported rates of current waterpipe smoking and susceptibility to cigarette smoking by demographic characteristics and by use of other tobacco products among survey participants aged 18 to 24 years. Multivariable logistic regression was used to examine the relationship between current waterpipe smoking and susceptibility to cigarette smoking, defined as the lack of a firm intention not to smoke soon or within the next year. RESULTS: Of 2,528 young adults who had never established cigarette smoking, 15.7% (n = 398) reported being waterpipe smokers (every day or some days [n = 97; 3.8%] or rarely [n = 301; 11.9%]); 44.2% (176/398) of waterpipe smokers reported being susceptible to cigarette smoking. Those who smoked waterpipe rarely were 2.3 times as susceptible to cigarette smoking as those who were not current waterpipe smokers (OR = 2.3; 95% CI, 1.6-3.4). CONCLUSION: Current waterpipe smoking is associated with susceptibility to cigarette smoking among young adults in the United States. Longitudinal studies are needed to demonstrate causality between waterpipe smoking and initiation of cigarette smoking.

Hookah tobacco smoking may be viewed differently by males and females. For example, females have been drawn to types of tobacco that are flavored, milder, and marketed as more social and exotic. Individuals often use the growing segment of anonymous social networking sites, such as Tumblr, to learn about potentially dangerous or harmful behaviors. We used a systematic process involving stratification by time of day, day of week, and search term to gather a sample of 140 Tumblr posts related to hookah tobacco smoking. After a structured codebook development process, 2 coders independently assessed all posts in their entirety, and all disagreements were easily adjudicated. When data on poster sex and age were available, we found that 77% of posts were posted by females and 35% were posted by individuals younger than 18. The most prominent features displayed in all posts were references to or images of hookahs themselves, sexuality, socializing, alcohol, hookah smoke, and tricks performed with hookah smoke. Compared with females, males more frequently posted images of hookahs and alcohol-related images or references. This information may help guide future research in this area and the development of targeted interventions to curb this behavior.

Our analysis was conducted to compare the national baseline prevalence rate estimates of WTS among Arab boys and girls. DESIGN SETTING AND PARTICIPANTS: The Global Youth Tobacco Survey (GYTS) is a school-based survey using standardized self-administered questionnaires; it employs a two-stage cluster sampling technique to obtain a representative sample of youth (13-15 years of age). We conducted a secondary data analysis of nationally representative GYTSs available from 16 Arab countries. MAIN MEASURES: Youth who self-reported smoking waterpipe at least once in the past 30 days were considered to be current waterpipe tobacco smokers. National weighted WTS prevalence rate estimates along with respective 95% confidence intervals were reported for boys and girls. RESULTS: Pooled GYTS data from 16 Arab countries yielded a total of 31,359 youth. Overall, 10.6% of the respondents were current waterpipe tobacco smokers, with boys (13.7%) having significantly higher estimates than girls (7.2%). Overall, current WTS prevalence rate estimates ranged from .9% in Oman to 34.2%, in Lebanon. The WTS epidemic was more predominant among boys and girls, respectively, in the West Bank (42.8% and 24.2%), Lebanon (38.6% and 30.5%) and Jordan (25.7% and 14.5%). CONCLUSION: Among Arab boys and girls, WTS represents a growing strain of the tobacco epidemic that requires immediate attention.

PARTICIPANTS: AA college students (N = 1,402; mean age = 20, range = 18-24 years; 75% female) who completed the Fall 2012 American College Health Association-National College Health Assessment II. METHODS: Respondents were stratified into 4 mutually exclusive groups by last-30-day smoking status: cigarette-only use (5.1%), hookah-only use (5.9%), dual use (2.4%), and nonuse (86.6%). Multinomial logistic regression models identified the relative odds of exclusive and dual hookah and cigarette smoking. RESULTS: Current hookah and cigarette smoking rates were comparably low. Age, gender identity, current substance use, interest in tobacco use information, and student population prevailed as risks and protections for hookah and cigarette smoking. CONCLUSIONS: Campus health promotion campaigns may need to tailor messages to AA students, particularly those who use substances, to underscore the health risks of hookah and cigarette smoking.

We sought to address this by calculating the prevalence of waterpipe smoking among secondary school students in southeast London. METHODS: We conducted a pooled secondary analysis of routine health surveillance surveys among 11-17 year olds in convenience-sampled secondary schools from three ethnically-diverse areas of southeast London. We calculated ever (lifetime) waterpipe use, and compared its sociodemographic correlates to ever (lifetime) cigarette use. In one area we collected data on patterns of waterpipe use. RESULTS: Of 2,098 respondents (mean age 14.1 +/- 1.7 years, 55.7 % male, 46.6 % of black ethnicity), ever waterpipe use was 39.6 % (95 % CI 37.6-41.7 %) and was higher than that for ever cigarette use (32.4 %; 95 % CI 30.5-34.4). While waterpipe users were significantly and independently more likely to be male and of non-white ethnicities, at least 30 % of all age, gender and ethnic sub-groups had tried waterpipe smoking. In contrast, cigarette users were more likely to be older and of white ethnicity. In one of the three areas, over a quarter of waterpipe users were occasional or regular waterpipe smokers, and most were introduced to and currently used waterpipe in waterpipe-serving premises or friends' homes. CONCLUSIONS: Waterpipe smoking prevalence was high in southeast London, and users exhibited a different sociodemographic profile to cigarette users. Waterpipe should be included in national health surveys of young people. National surveillance is warranted to help develop suitable interventions to prevent uptake and promote cessation.

The effect of chlorination was partial as a residual biofilm persisted and was time-limited as repopulation occurred immediately after water resupply. The total number of bacteria reached the same levels on both the bare and chlorinated biofilm-fouled HDPE after a seven-day exposure to drinking water. Due to the presence of a residual biofilm, the hydrophobicity of chlorinated biofilm-fouled surface exhibited much lower adhesion forces (2.1 nN) compared to bare surfaces (8.9 nN). This could explain the rapid repopulation after chlorination, with a twofold faster bacterial accumulation rate on the bare HDPE surface. gamma-Proteobacteria dominated the early stages of repopulation of both surfaces and a shift in the dominance occurred over the colonization time. Such observations define a timescale for cleaning frequency in industrial environments and guidelines for a rinsing procedure using drinking water.

Hookah use is associated with other forms of substance use, but most research has been cross-sectional, thus limiting our understanding of temporal patterns of use. The goals of this longitudinal study were to assess the prevalence of hookah use and initiation, as well as other forms of substance use among hookah users, and identify which forms of substance use predicted hookah initiation during the first 30 days of college. METHODS: Incoming students (N = 936, 50% female) reported on past 30-day substance use prior to the start of the Fall 2011 semester and again 30 days later (n = 817). Substances included hookah, cigarettes, other forms of tobacco, alcohol, marijuana, and other illegal drugs. RESULTS: Current prevalence of hookah use increased from 9.0% before college to 13.1% during the first month of college. At baseline and follow-up, current hookah users were more likely than nonusers to report current use of cigarettes, cigars/little cigars/clove cigarettes, smokeless tobacco, marijuana, and alcohol. Among pre-college hookah never users, 13.8% initiated hookah use in the first month of college. Alcohol (adjusted odds ratio [AOR] 1.11, 95% confidence interval [CI] 1.05, 1.17) and marijuana (AOR 1.30, 95% CI 1.03, 1.65) were the only substances predictive of hookah initiation. CONCLUSIONS: Findings indicate that hookah prevention and intervention is needed during the transition to college, and interventions may need to address comorbid alcohol, marijuana, and hookah use. IMPLICATIONS: To our knowledge this is the first longitudinal study examining predictors of hookah initiation among male and female incoming first-year college students. While hookah users were more likely than nonusers to use all other substances before and during the first month of college, pre-college marijuana and alcohol use were the only two predictors of hookah initiation during the first 30 days of college. Collectively, these findings provide additional support for the need for efficacious hookah prevention and intervention programs. The transition to college appears to be an ideal time to deliver prevention programs given the increased prevalence of hookah use during the first 30 days of college. In addition to prevention, former users may benefit from targeted relapse prevention as one-fifth of former hookah smokers resumed use during the first 30 days of college.

DESIGN AND METHODS: This anonymous online survey was conducted with all students enrolled in a college of nursing. The survey utilized measures from several national tobacco studies to assess knowledge and beliefs about ATPs (hookahs, cigars or cigarillos, bidis, kreteks, smokeless tobacco, electronic cigarettes) compared to cigarettes, health effects of ATPs, personal use of ATPs, and social norms. Data were analyzed in SPSS 22.0 (SPSS Inc., Chicago, IL, USA). Descriptive statistics and frequencies were performed for basic sociodemographic data. Paired samples t tests were performed to determine differences for scaled measures. FINDINGS: Nursing students demonstrated very low levels of knowledge about ATPs and their health consequences, despite high rates of ATP personal use. About 76% of participants reported use of one or more ATPs once or more in their lifetimes. A greater proportion of students had used hookahs or waterpipes (39.6%) compared to cigarettes (32.7%). CONCLUSIONS: Nurses' lack of knowledge about the emerging use and health threats associated with ATPs may undermine their ability to provide appropriate tobacco cessation counseling. Research is needed to identify gaps in nurses' education regarding tobacco cessation counseling and to develop new counseling approaches specific to use of ATPs. CLINICAL RELEVANCE: Nurses play critical roles in counseling their patients for tobacco cessation. Further research and education about the risks presented by ATPs are critical to reducing excess tobacco-related mortality.

Our paper presents the development process for these guidelines. A group of national and international experts was formed and a national situation analysis for tobacco dependence treatment practices and a detailed review of international evidence were conducted. The guidelines were then drafted and reviewed by national, regional and international experts and were official endorsed by the Jordanian Ministry of Health before being launched. The guidelines comprise concise descriptions and practical supplementary flowcharts covering the major elements of general tobacco dependence treatment. These are the first comprehensive Arabic-language guidelines, including a section focusing on waterpipe use, and we believe they are a reliable and useful resource for neighbouring countries seeking to develop similar guidelines.; Publisher: Abstract available from the publisher.; Publisher: Abstract available from the publisher.
