Objective: The aim of this study was to analyze those factors associated with cigarette smoking in adolescent school children, in order to plan future school interventions for promoting good health strategies developed by the schools and Primary Health Care professionals.
Design: Cross-sectional study with a two-stage cluster sampling.
Setting: The study included 97 schools, and was carried out in 2005-06 in Catalonia (Spain).
Participants: 14-16 year-old secondary school children.
Main measures: The survey was based on a self-administered paper-based questionnaire that collected sociodemographic variables, academic level, health status, family variables, sexual relations, addictive substances, mood state, and variables related to opinions on cigarette smoking The association between these variables and smoker/non-smoker variable was analyzed, as well as factors that could increase the probability of becoming a smoker using multilevel models.
Results: A total of 9340 completed questionnaires, including 4653 from males, were received from the pupils, with a mean age of 15.2 years. The results showed that 71.1% of pupils were non-smokers, 75% of whom were males and 67.3% of females. The following factors increased the probability of becoming a smoker (OR and 95%CI): being a female 0.60 (0.53-0.68), being in the 4(th) year 1.27 (1.12-1.43), low academic performance 3.38 (2.74-4.17), self-reported regular/poor health status 2.81 (2.21-3.58), smoking parents 1.68 (1.45-1.95), alcohol consumption 5.05 (4.35-5.86), having 3 or more problems of mood state 1.22 (1.05-1.41), living without parents 1.59 (1.07-2.38), agreeing with tobacco industry advertising 1.64 (1.45-1.85) and believing that tobacco acts as a relaxant 3.57 (3.23-4.17).

Emplazamiento: Se incluyeron 97 centros escolares de Cataluña, 2005-2006.

Mediciones principales: Encuesta autoadministrada que recogía variables sociodemográficas, académicas, estado de salud, familiares, relaciones sexuales, sustancias adictivas, estados de ánimo y variables de opinión sobre el consumo.

Resultados: Se incluyeron 4.653 chicos y 4.687 chicas, con una edad media de 15,2 años. El 71,1% de los estudiantes eran no fumadores, el 75% de los chicos y el 67,3% de las chicas. Aumentaban la probabilidad de ser fumador (OR e IC 95%): ser chica 0,60 (0,53-0,68), cursar 4.o ESO 1,27 (1,12-1,43), tener un rendimiento escolar bajo 3,38 (2,74-4,17), tener una autopercepción de salud regular/mala 2,81 (2,21-3,58), tener padres fumadores 1,68 (1,45-1,95), consumir alcohol 5,05 (4,35-5,86), tener 3 o más problemas de estado de ánimo 1,22 (1,05-1,41), vivir sin ningún progenitor 1,59 (1,07-2,38), estar de acuerdo en que exista publicidad sobre tabaco 1,64 (1,45-1,85), y opinar que el tabaco ayuda a relajarse 3,57 (3,23-4,17).
