Sex under the influence of alcohol among Norwegian adolescents.

The purpose of this paper is to study alcohol consumption among Norwegian 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 boys had coital experience). Data were collected by means of questionnaires; 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 enjoyment and sexual intercourse motivated by "Don't know, it just turned out that way". Adolescents who had their most recent experience of intercourse away from home, who had problems enjoying sex and/or who said it just turned out that way, were more likely than others to have had sex under influence of alcohol. A multivariate logistic regression analysis showed that among adolescents who reported that the intercourse took place away from their homes, the odds ratio (OR) for sex under influence of alcohol increased by 8.7. Those who had consumed alcohol before sex, more often than non-drinkers, tended to enter into sexual intercourse motivated by factors external to their own person. This tendency was more pronounced among boys than girls.
