Variabilidad en la experimentación tabáquica y en sus factores de riesgo en 4 centros educativos de la Región de Murcia

Objective. To identify patterns of tobacco experimentation and consumption in 4 geographically close groups of students in the first year of secondary education, as well as attitudes and consumption in their social environments. To identify the factors associated with tobacco experimentation and consumption in each of the student groups. Material and method. An observational, descriptive, cross-sectional, multicenter study was conducted in 4 secondary schools in the region of Murcia (Spain). The study population consisted of first graders in secondary education, recruited in January 2005. The study variables were collected using a modified version of the FRISC questionnaire. Results. The study population was composed of 377 students (190 boys) with a mean age of 12.6 years (standard deviation [SD] = 0.6). Between 15.3% and 42.1% of the students had smoked at some time. Between 2% and 6.9% smoked regularly. These differences were related to socioeconomic characteristics ("living with the mother", p = 0.049; "living with the father", p = 0.015) and consumption in the environment ("mother", p = 0.013; "friends", p < 0.001; "teachers", p < 0.001). Multivariate analysis revealed an association between experimentation and receiving more than 6R per week pocket money, consumption among friends, experimenting with alcohol and not living in one of the towns studied. Conclusions. Significant differences were found among the towns studied. Application of standard preventive programs may prove ineffective unless they are adapted to the characteristics of the specific school.
