[Adolescent daily smoking, negative mood-states and the role of family communication].

Objective: To determine whether negative mood states constitute a risk factor for daily smoking during adolescence, and to specify the role of familial factors in the association between the two variables.

Methods: Cross-sectional study of a representative sample (second wave, Panel of Families and Childhood) of Catalan adolescents between 14 and 18 years of age. Six logistic regression models were used for girls (n = 1,442) and six for boys (n =1,100) in order to determine whether negative mood states constitute a risk factor for daily cigarette consumption, and to what extent this effect is attributable to familial factors.

Results: The prevalence of daily smoking at ages 17-18 is 3.8% for girls and 3.6 for boys. Feelings of sadness constitute a risk factor for daily cigarette consumption (odds ratio [OR] = 1.633), and communication with the father cancels out this effect. Parental pressure is a risk factor for daily smoking in both sexes (girls, OR = 2.064; boys, OR = 1.784). When parental communication is controlled for, this effect is reduced but not canceled out. Living in a reconstituted family is a risk factor for daily cigarette consumption among boys (OR = 2.988).

Conclusions: Intergenerational communication decreases the risk of daily tobacco use among adolescents independently of their mood state. Anti-smoking interventions designed in accordance with these findings may be more effective.
