Background. In 1985, The Minnesota Legislature initiated a long-term a
nd broad-based program to deter adolescent tobacco use. The initiative
was funded by higher taxes on tobacco products and combined school-ba
sed programming, mass-media campaigns, and local community grants. The
Minnesota-Wisconsin Adolescent Tobacco-Use Research Project was desig
ned to evaluate this effort by monitoring adolescent tobacco use and r
elated factors in Minnesota and Wisconsin from 1986 to 1990. The resul
ts presented in this paper indicate that the Minnesota initiative dram
atically increased Minnesota schoolchildren's reported exposure to the
anti-smoking messages in the mass media but had little effect on smok
ing-related beliefs or smoking behaviors. Conclusions. These results,
together with the findings from other recent studies, suggest that eve
n dramatic increases in exposure to anti-tobacco messages in the mass-
media, in the absence of a substantial and sustained school-based toba
cco prevention measures, may be insufficient to generate reductions in
adolescent tobacco use. (C) 1994 Academic Press, Inc.
