This paper examined changes in the influence of parents' and close friends' smoking on smoking transitions occurring over the course of adolescence, using a large (N=6,006) longitudinal study. The three grade periods were 5th to 7th (ages 10-12), 7th to 9th (ages 12-14), and 9th to 12th grade (ages 14-17). Smoking transitions examined were: (1) never to trying, (2) trying to monthly, and (3) monthly to daily. Results showed that the influence of parents' smoking was substantial for all three transitions during most of the grade periods and, for the transition from monthly to daily smoking, increased (p=.006) during adolescence. In contrast, the influence of close friends' smoking was strongest for the transition to trying smoking and did not significantly change (all p>.05) for any of the smoking transitions as the adolescent became older. In conclusion, the influence of close friends' smoking on smoking transitions might be stable during adolescence whereas the influence of parents' smoking on the transition to daily smoking might markedly increase across adolescence.
本文利用一项大型纵向研究（N = 6,006），考察了父母吸烟和密友吸烟对青少年时期吸烟转变的影响变化。三个年级阶段分别为五年级至七年级（10 - 12岁）、七年级至九年级（12 - 14岁）以及九年级至十二年级（14 - 17岁）。所考察的吸烟转变情况包括：（1）从不吸烟到尝试吸烟，（2）尝试吸烟到每月吸烟，以及（3）每月吸烟到每日吸烟。结果显示，在大多数年级阶段，父母吸烟对所有这三种转变都有显著影响，并且对于从每月吸烟到每日吸烟的转变，在青少年时期影响有所增加（p = 0.006）。相比之下，密友吸烟对开始尝试吸烟的转变影响最强，并且随着青少年年龄增长，对于任何吸烟转变而言其影响均无显著变化（所有p > 0.05）。总之，密友吸烟对吸烟转变的影响在青少年时期可能较为稳定，而父母吸烟对转变为每日吸烟的影响在整个青少年时期可能会显著增加。
