Prevalence and predictors of alcohol and tobacco consumption in adolescence. [Preval y factores de predic. de los comport. de riesgo en la adolesc.: el papel de la condición de peso, condic. clínica y dimensiones psicosoc.

Abstract

The aim of this study was to examine the prevalence of alco- hol/tobacco consumption among adolescents (N = 370) aged 14 to 19 years in three groups: 205 adolescents with normal weight, 82 adolescents from the community with overweight or obesity, and 83 adolescents with overweight or obesity and in outpatient treatment for weight control. We also examined the roles of age, gender, weight, treatment condition, and psychosocial variables (psychopathological symptoms, social support, and emotional skills) in the presence of those risk behaviors. Our major find- ings were that the clinical group of overweight adolescents had fewer risk behaviors, than the overweight community group and the normal weight controls, particularly for risk behaviors related to alcohol use. The increase of age and lower satisfaction with family predicted tobacco consumption. The increase of age, not being integrated in a treatment for weight control and higher satisfaction with intimate relationships predicted alcohol con- sumption. Weight status was not a predictor of alcohol and cigarette use. This study discusses the theoretical and practical implications of these find- ings.
