The purpose of this paper is to study alcohol consumption among Norweg
ian adolescents at their most recent experience of sexual intercourse.
The material comprises a stratified sample of 920 adolescents aged 16
-20 years in a Norwegian county (52.3% of the girls and 41.4% of the b
oys had coital experience). Data were collected by means of questionna
ires; 21.0% of the adolescents reported sex under influence of alcohol
A logistic regression analysis showed that the best predictors of sex
under influence of alcohol were intercourse location, sexual enjoymen
t and sexual intercourse motivated by ''Don't know, it just turned out
that way''. Adolescents who had their most recent experience of inter
course away from home, who had problems enjoying sex and/or who said i
t just turned out that way, were move likely than others to have had s
ex under influence of alcohol. A multivariate logistic regression anal
ysis showed that among adolescents who reported that the intercourse t
ook place away from their homes, the odds ratio (OR) for sex under inf
luence of alcohol increased by 8.7. Those who had consumed alcohol bef
ore sex, more often than non-drinkers, tended to enter into sexual int
ercourse motivated by factors external to their own person. This tende
ncy was more pronounced among boys than girls.
