Newer studies indicate that the decline in adolescent smoking observed in Norway in recent years has levelled off and that, in some groups, smoking seems to be increasing. The number of adolescents who experiment with tobacco has remained fairly constant. In this article we present findings from a prospective cohort study on the development of regular smoking among adolescents 13 to 16 years of age. The study started in 1990 with a representative sample of 13 year old adolescents (N = 1,195) in the county of Hordaland, Norway. Data from follow-up studies conducted in 1991, 1992 and 1993 are included. The results indicate that more than 60% of the adolescents had tried to smoke by the age of 15. For about half of those who tried, the experimentation marks the beginning of a smoking career that develops from occasional to regular smoking. By the age of 16, 28% of the girls and 16% of the boys had become daily smokers. Smoking status at age 13 is a strong predictor of regular smoking three years later. For this reason, early adolescence is a period of primary importance with respect to prevention of smoking.
最新研究表明，挪威近年来青少年吸烟率的下降趋势已趋于平稳，而且在一些群体中，吸烟率似乎还在上升。尝试吸烟的青少年人数一直相当稳定。在本文中，我们展示了一项针对13至16岁青少年定期吸烟发展情况的前瞻性队列研究的结果。该研究始于1990年，以挪威霍达兰郡具有代表性的13岁青少年样本（N = 1195）为对象。研究纳入了1991年、1992年和1993年随访研究的数据。结果表明，超过60%的青少年在15岁时就已尝试吸烟。对于约半数尝试吸烟的青少年来说，这种尝试标志着吸烟生涯的开始，从偶尔吸烟发展为经常吸烟。到16岁时，28%的女孩和16%的男孩成为了每日吸烟者。13岁时的吸烟状况是三年后经常吸烟的有力预测指标。因此，青春期早期对于预防吸烟至关重要。
