我国青少年吸烟行为的代际传递研究

Parental Smoking and Adolescent Smoking:the Intergenerational Transmission of Heath-risk Behaviors

目的了解我国12～18岁青少年吸烟情况，探讨父母吸烟行为对青少年吸烟行为的代际传递影响。方法利用1991~2009年中国健康与营养调查（CHNS）数据，采用logistic回归模型和Tobit回归模型分析父母吸烟对青少年吸烟行为的代际传递影响。结果全国12～18岁的青少年吸烟率达2．35％，父母吸烟是影响青少年吸烟的重要危险因素，父亲吸烟行为还可影响青少年的每日吸烟量。结论我国青少年吸烟现象较严重，父母吸烟对青少年吸烟行为具有代际传递影响，控制父母吸烟可以有效降低青少年吸烟以及每日吸烟数量。

Objective To determine the impact of parental smoking on adolescent smoking. Methods Data were retrieved from the China Health and Nutrition Surveys. Both Logistic regression and Tobit regression analyses were performed to estimate the intergenerational effects. Results The prevalence of adolescent smoking was 2. 35%. The Logistic regression results showed that parental smoking was a risk factor for adolescent smoking. Estimations from Tobit regression showed that father smoking was also correlated with the numbers of cigarettes adolescent smoked. Conclusion An intergenerational effect was observed between parental smoking and adolescent smoking. In order to reduce adolescent smoking, parental smoking control should be targeted.
