36. Growing U.S. Prevalence 200-300 new waterpipe cafés opened in the U.S. between 1999 and 2004
Particularly in college towns
Convenience sample surveys suggest high current use (past 30 days)
411 first-year college students: 15.3%
744 introductory psychology students: 20%
37. Holes in Literature Random sample
Associations between waterpipe smoking and
Demographics
Beliefs (e.g., harm, addiction, popularity)
Populations outside college
38. STUDY 1: COLLEGE
39. Purpose Determine the 30-day, annual, and lifetime prevalence of waterpipe smoking in a random sample of college students
Determine associations between outcome variables and sociodemographic and predictors
40. Design Cross-sectional survey
Random sample of students at the University of Pittsburgh
Collect data via web-based version of the American College Health Association’s (ACHA) National College Health Assessment (NCHA)
Added items related to waterpipe use
41. Approvals University of Pittsburgh Institutional Review Board
University Vice Provost
42. Procedure April 2007 during a three-week period
Avoided the 30-day period following Spring Break
Email invitation sent to 3600 randomly selected Pitt students
Incentive: lottery to win cash prizes ranging from $25 to $100
Three reminder e-mails sent to students during the three-week period
43. Demographic Measures Age
Gender
Race
Residence (on-vs. off-campus)
Undergraduate vs. graduate
Membership in a fraternity or sorority
Self-reported academic achievement
44. Theory of Reasoned Action
45. Behavior Measures Have you ever smoked tobacco from a waterpipe (hookah, shisha, narghile), even one or two puffs? (Yes/No)
During the past year, have you smoked tobacco from a waterpipe (hookah, shisha, narghile), even one or two puffs? (Yes/No)
During the past 30 days, have you smoked tobacco from a waterpipe (hookah, shisha, narghile), even one or two puffs? (Yes/No)
46. 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”)
47. 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)?” (0-100%, collapsed into tertiles
48. Analysis Multivariate logistic regression models
Dependent variables
30-day waterpipe smoking
One year waterpipe smoking
Independent variables
Perception of harm
Perception of addictiveness
Acceptability
Popularity
Covariates
Sensitivity analyses with stepwise regression
49. Response Rate 61 emails undeliverable
Response rate 660/3539 = 18.6%
647/660 (98.0%) had outcome data
Compared with non-respondents, respondents were:
Younger (20.9 vs. 21.4, p<0.001)
Female (65.6% vs. 50.5%, p<0.001)
Caucasian (85.4% vs. 80.7%, p=0.004)
50. Sample
51. Smoking Data
52. Past-Year Waterpipe Tobacco Smoking
53. Harm, Addictiveness
54. Acceptability, Popularity
59. Other Factors Associated with1-Year WPTS Younger age
Off campus
Fraternity membership
60. 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
61. Cigarettes vs. Waterpipe Many waterpipe smokers had never smoked cigarettes
In non-cigarette smokers
Problematic
Introducing nicotine to previously naďve population
In cigarette smokers
Substitution?
Augmentation?
62. 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.
63. Limitations Response rate: 18.6%
Demographic differences between respondents and non-respondents
May have inflated our results since younger population more likely to smoke waterpipe
Cross-sectional design
64. Conclusion First random sample
Ever use common in this sample
Further research
Longitudinal designs
National samples (NCHA)
Educational/interventional efforts
Major educational gaps
Worthwhile to start now
Focus on addictiveness, acceptability, popularity
