Kaplan-Meier estimates were used to study age at first intercourse among Norwegian adolescents. The data stemmed from a nation-wide study of 3,000 Norwegian adolescents aged 17-19 years. The response rate was 61.8%. Median age at first intercourse was 17.3 years for girls and 18.0 years for boys. The results indicate that median age at first intercourse has not become lower in Norway since 1975. Age at first intercourse was significantly associated with educational aspirations and frequency of visits to church by respondents and parents. Furthermore, age at first intercourse was significantly associated with smoking behaviour, alcohol consumption, peer affiliation and frequency of visiting a discotheque. These inter-relationships confirm that age at first intercourse is an important indicator of the lifestyle of an individual. Thus, in order to influence the sexual behaviour of adolescents it thus seem appropriate, as a supplement to traditional methods of sex education, to employ health promotion activities which focus on environmental and structural factors.
采用Kaplan-Meier估计法研究挪威青少年首次性交的年龄。数据来源于一项对3000名17至19岁挪威青少年的全国性研究。应答率为61.8%。女孩首次性交的中位年龄为17.3岁，男孩为18.0岁。结果表明，自1975年以来，挪威首次性交的中位年龄并未降低。首次性交的年龄与受访者及其父母的教育期望和去教堂的频率显著相关。此外，首次性交的年龄与吸烟行为、饮酒、同伴关系以及去迪斯科舞厅的频率显著相关。这些相互关系证实，首次性交的年龄是个人生活方式的一个重要指标。因此，为了影响青少年的性行为，作为传统性教育方法的补充，开展关注环境和结构因素的健康促进活动似乎是合适的。
