title: Movie smoking and urge to smoke among adult smokers.
abstract: BACKGROUND
  Few studies have assessed the association between exposure to movie smoking and urge to smoke under real-world conditions.
  
  
  METHODS
  We conducted exit interviews with 4,073 movie patrons, of whom 2,817 were aged 18 years or older. Some 536 were smokers and had complete data. Subjects had exited 26 movies, of which 12 contained smoking. We used least squares regression to assess the association between exposure to movie smoking and urge to smoke (scale range 0-10), controlling for movie rating, age, sex, heaviness of smoking index (HSI, range 0-6), and time since last cigarette smoked.
  
  
  RESULTS
  Median age was 27 years and 52% were female. Median urge to smoke level at movie exit was 7. The dose-response between higher categories of movie smoking and median urge to smoke was one point for two lower categories (1-11 and 11-54 s) and two for the highest category (>or=55 s), but these differences were not statistically significant. In the multivariate analysis, attendance of a movie with smoking was associated with a 0.81-point increase (95% CI = 0.46-1.16) in urge to smoke. For comparison, an HSI score of 3 (vs. 0) was associated with a 2-point increase in urge to smoke.
  
  
  CONCLUSIONS
  In this sample of adult smokers, exposure to movie smoking was associated with higher urge to smoke after the movie, independent of movie rating. The effect size was consistent with responses seen in cue reactivity experiments. Exposure to movie smoking may affect urge to smoke among adult smokers.
