Increased adolescent drunkenness in Finland has called for research to expl
ore the background of this development. This study seeks to find out to wha
t extent the societal level changes have contributed to the increased drunk
enness among 14 year olds in Finland from 1981 to 1997, The data set is dra
wn from a nationally representative hi-annual mail study, the Adolescent He
alth and Lifestyle Survey, conducted since 1981 (N = 792-2533, response rat
e 77-90% per year). Logistic regression analysis was used to study the effe
ct of several background factors on the drunkenness prevalence trend. Famil
y structure, parental education, residence urbanization, weekly allowance a
nd timing of biological maturation were associated with drunkenness. Change
s within the distribution of these factors, especially in increased weekly
allowance and earlier timing of biological maturation, appeared to account
for a considerable part of the increased drunkenness from 1981 to 1997. The
findings suggest that increased adolescent drunkenness is significantly as
sociated with societal changes outside the scope of health and alcohol poli
cies.
