Objective: We describe the prevalence of bush party (an outdoor gather
ing of youth) attendance and examine predictors of attendance and of d
riving after drinking at bush parties. Method: The 1995 Ontario Studen
t Drug Use Survey (OSDUS) data on students (n = 1,853) in schools acro
ss the province in grades 7, 9, 11 and 13 are employed to estimate pre
valence of bush party attendance within the previous 12 months. The 19
94 Graduated Licensing Study (GLS), a multicommunity survey of drivers
(n = 1,157, 53.6% male) in grades 11 and 12 in Ontario, data are empl
oyed to study predictors of attendance and of drinking-driving. Result
s: Based on the OSDUS, the prevalence of bush party attendance is 37.6
%. Based on the GLS, 38.4% attended bush parties, and among attenders
71.5% drank at bush parties, 63.5% observed drinking-driving, 16.1% ro
de with a drinking-driver and 16.6% drove after drinking at bush parti
es. Logistic regression reveals that attendance at bush parties is pos
itively associated with number of other places alcohol was consumed, t
obacco use, number of alcohol-related problems, number of kilometers e
ver driven, sensation seeking and northern residents. Among attenders
who drank at bush parties, males were three and a half times more like
ly to drive after drinking at a bush party, and the probability of dri
nking and driving increased with the number of other drugs used. Concl
usions: Despite important differences in the design and purpose of the
two surveys, both indicate that bush party attendance is prevalent am
ong adolescents. Driving after drinking at these events is common and
warrants community action.
