Age at first intercourse among Norwegian adolescents was studied by means of survival analysis. The data stemmed from a nation-wide survey of 3000 Norwegian adolescents aged 17-19, yielding a response rate of 61.8%. Median age at first intercourse was 17.3 years among girls and 18.0 years among boys. By means of Cox regression analysis associations between age at onset of intercourse and some correlates were estimated. Age at first intercourse was significantly associated with educational aspirations, smoking behaviour, alcohol consumption, peer affiliation, and frequency of visiting a discotheque. These inter-relationships confirm that age at onset of intercourse comprise an important indicator of the lifestyle of an individual. In order to influence sexual behaviour of adolescents it may thus be appropriate to employ health promotion activities focusing upon environmental and structural factors, as a supplement to traditional methods of sex education.
通过生存分析研究了挪威青少年首次性交的年龄。数据来源于对3000名17 - 19岁挪威青少年的全国性调查，回复率为61.8%。女孩首次性交的中位年龄为17.3岁，男孩为18.0岁。通过Cox回归分析估计了性交开始年龄与一些相关因素之间的关联。首次性交年龄与教育期望、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，性交开始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，除了传统的性教育方法外，采用关注环境和结构因素的健康促进活动可能是合适的。
