The influence of parental separation on smoking initiation in adolescents.

Most adult smokers start smoking when they are adolescents and, the prevalence of smoking declines less than other unhealthy behaviors as people mature. Understanding why adolescents start smoking is, therefore, key to developing effective policy aimed at lowering the prevalence of smoking in both children and adults. In this study, I suggest that parental separation is one possible risk factor for smoking initiation. I use a nationally representative sample of American adolescents interviewed at two points in time to examine the influence of parental separation on smoking initiation. Two questions are addressed. First, is there a relationship between parental separation and the likelihood that an adolescent will initiate smoking? Second, if there is a relationship, through what factors does parental separation operate to influence the initiation of smoking in adolescents? My findings suggest that parental separation increases the likelihood that adolescents will start smoking. It does so in part by raising depressive symptoms and rebelliousness in adolescents. Despite the significance of these indirect effects, however, the bulk of the effect of parental separation on smoking initiation is direct.
