Have you ever smoked tobacco from a waterpipe (hookah, shisha, narghile), even one or two puffs? (Yes/No) 2. During the past year, have you smoked tobacco from a waterpipe (hookah, shisha, narghile), even one or two puffs? (Yes/No) 3. During the past 30 days, have you smoked tobacco from a waterpipe (hookah, shisha, narghile), even one or two puffs? (Yes/No) Attitudes • “Would you say that smoking from a waterpipe (hookah, shisha, narghile) is more harmful or less harmful than smoking regular cigarettes?” (“waterpipe more harmful” / “waterpipe same harm” / “waterpipe less harmful”) • “Would you say that smoking from a waterpipe (hookah, shisha, narghile) is more addictive or less addictive than smoking regular cigarettes?” (“waterpipe more addictive” / “waterpipe same addictiveness” / “waterpipe less addictive”) Normative Beliefs • “Among your peers, how socially acceptable is it to smoke tobacco from a waterpipe (hookah, shisha, narghile)?” (“not acceptable” / “somewhat/moderately acceptable” / “very acceptable”) • “What percentage of college students do you think has ever smoked tobacco from a waterpipe (hookah, shisha, narghile)?” (0100%, collapsed into tertiles Response Rate • 61 emails undeliverable • Response rate 660/3539 = 18.6% • 647/660 (98.0%) had outcome data Sample Age (mean, SD) 20.9 (2.0) Female (%) 65.6 White (%) 84.5 On Campus (%) 39.9 Undergraduate (%) 77.2 Fraternity/Sorority (%) 8.5 Smoking Data Percentage 45 40 35 30 25 20 15 Cigarettes Waterpipe 10 5 0 Ever Past 30 Days Past-Year Waterpipe Tobacco Smoking Percentage 70 60 50 40 30 20 10 0 Among All Respondents Among Cigarette Smokers Among NonSmokers Percent Harm, Addictiveness 90 80 70 60 50 40 30 20 10 0 Non-Users WP Users WP Less Harmful WP Less Addictive Acceptability, Popularity 70 60 Percent 50 40 Non-Users WP Users 30 20 10 0 WP Very Acceptable WP Very Popular Other Factors Associated with 1-Year WPTS • Younger age • Off campus • Fraternity membership Major Findings • Lifetime use >40%, similar to cigarette lifetime use • Current use 9.5% • One year use 30.5% • Associated with lack of concern for addictiveness (and harm, less so) • Associated with sense of acceptability and popularity Cigarettes vs. Waterpipe • Many waterpipe smokers had never smoked cigarettes • In non-cigarette smokers – Problematic – Introducing nicotine to previously naïve population • In cigarette smokers – Substitution? – Augmentation? Rate Differences • 30-day rate (9.5%) much lower than annual (30.6%) and ever (40.5%) rates • Sampling period: we avoided Spring Break, fraternity rush, etc. Limitations • Response rate: 18.6% • Cross-sectional design STUDY 2: HIGH SCHOOL Purpose • Determine prevalence in statewide sample of high school students • Association with waterpipe use in high school No High School National Data • Monitoring the Future • Youth Risk Behavior Surveillance Survey • Others Arizona 2005 • Youth tobacco survey • Added 2 items dealing with waterpipe tobacco smoking – Ever – Past 30 days Participants • Statewide representative sample • Grades 6-12 • All students enrolled in public and/or charter schools Procedure • Schools chose to use active or passive consent forms (89% used passive) • Spring semester 2005 • 45 minute class period Measures • Tobacco – 30-day waterpipe smoking – Ever waterpipe smoking – Other tobacco smoking • Sociodemographic data – Age – Gender – Race – Type of school (charter vs. regular) – Plan to attend college Waterpipe Tobacco Smoking in Arizona Youth Percent 16 14 Ever 12 Past 30 Days 10 8 6 4 2 0 6th 7th 8th 9th Grade Level 10th 11th 12th High School Seniors' Use of Tobacco Products in Arizona 60 50 Ever Past 30 Days 30 20 10 et ek s Kr Bi di s Pi pe ok el es s Sm ill o s ig ar C W at er pi pe s ig ar C ig ar et te s 0 C Percent 40 Waterpipe Smoking by Race 12.0 10.0 Percent 8.0 Ever Past 30 Days 6.0 4.0 2.0 0.0 AI/AN Black Hispanic Asian White H/PI Multivariate Analysis: Ever Use OR Ever Use (95% CI) Grade Level 1.6 (1.4, 1.7) Female 0.8 (0.6, 1.1) Asian 3.2 (1.2, 8.4) Black 1.3 (0.5, 3.5) Hispanic 1.4 (0.7, 2.9) Hawaiian/PI 2.5 (0.7, 9.4) White 3.2 (1.6, 6.4) Charter School 1.5 (1.2, 1.8) Plans to Attend College 0.5 (0.4, 0.6) Multivariate Analysis: 30-Day Use OR 30-Day Use (95% CI) Grade Level 1.4 (1.2, 1.5) Female 0.6 (0.4, 0.9) Asian 2.0 (0.6, 7.0) Black 1.0 (0.3, 3.4) Hispanic 1.4 (0.6, 3.4) Hawaiian/PI 2.5 (0.5, 12.1) White 2.1 (0.9, 5.0) Charter School 1.4 (1.1, 1.9) Plans to Attend College 0.7 (0.5, 0.98) Major Findings • History of waterpipe tobacco smoking – 6% of all 6th-12th graders – 15% of 12th graders • More common than 5 other methods of tobacco smoking • Associated with age, gender, race, SES Age • High school: older • College: younger • Surrogate for alcohol use? Experimentation vs. Addiction • May lead to increased uptake of various types of nicotine • Gateway to cigarette smoking? Surveillance • National studies (MTF, YRBS) should track this form of tobacco use • Likely to increase – Less harsh – Flavored – Educational gaps – Policy issues STUDY 3: NATIONAL PILOT DATA National College Health Assessment • Annual • American College Health Association • Instrument under revision since 2006 (NCHA II) • Addition of waterpipe items • Pilot Spring 2008 • N = 8745 (8 schools) Waterpipe vs. Cigarette 40 35 30 25 Waterpipe Cigarette 20 15 10 5 0 Ever Past 30 Days Waterpipe tobacco smoking 100 90 80 70 60 50 40 30 20 10 0 Reality Perception Ever Past 30 Days Other Tobacco Types 40 35 30 25 Ever Used Past 30 Days 20 15 10 5 0 Cigarettes Waterpipe * Includes little cigars, cigarillos Cigars* Smokeless By Age 40 35 30 25 Ever Used Past 30 Days 20 15 10 5 0 18 19 20 21 22-25 26-30 31+ By School 40 35 30 25 Ever Used Past 30 Days 20 15 10 5 0 200 201 202 203 204 205 206 207 By Living Arrangement 60 50 40 Ever Used Past 30 Days 30 20 10 ll A er O th re nt Pa s am pu Fr at O ffC C am pu s 0 Question—You Be the Judge! • Athletes – Varsity – Club – Intramural • Tobacco use – Waterpipe – Cigarette Adjusted Odds Ratio (95 % CI) for Ever Use 1.4 1.3 Waterpipe 1.2 Cigarettes 1.1 1 0.9 0.8 0.7 0.6 0.5 0.4 Varsity Club Sports Intramurals Adjusted Odds Ratio (95 % CI) for 30-Day Use 1.6 Waterpipe 1.4 Cigarettes 1.2 1 0.8 0.6 0.4 0.2 Varsity Club Sports Intramurals Implications • College athletes (and others) who would have otherwise been nicotine naïve may be vulnerable to developing lifelong nicotine dependence via waterpipe tobacco smoking • Waterpipe perceived as “different” Athlete Types • Varsity – Less social time? – Less risk tolerance due to sport commitment? • Intramural/Club – Campus leaders – More likely to engage in “trendy” behaviors – Perception as similar to alcohol? Different Tobacco Outcomes • Ever waterpipe smoking: 29.5% • Current waterpipe smoking: 7.2% – Lower power? – Try once or twice but not at risk for continued use? Limitations • Not nationally representative • Response rate 28% • No biochemical verification Conclusion • Waterpipe tobacco smoking represents a major potential threat to public health • Threatens to undermine successes from cigarette smoking • Surveillance and further research are necessary Thanks! bprimack@pitt.edu
