Abstract

INTRODUCTION:

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.

DISCUSSION:

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.
