Conocer la prevalencia de tabaquismo en estu-diantes universitarios que practican ejercicio físico.

Estudio descriptivo transversal con encuesta autoadministrada a la población universitaria que realiza ejercicio físico en el Servicio de Actividades Deportivas de la Universidad. Las variables de estudio son: edad, sexo, consumo de tabaco, cigarrillos/día, práctica de ejercicio físico previo, conocimiento de la legislación vigente en la Universidad sobre tabaco, opinión sobre la relación en-tre fumar y disminución del rendimiento físico y deseo de cesación tabáquica.

Se recogieron 406 cuestionarios (el 41,2% de la población diana), un 71,7% respondidos por mujeres, y un 28,3% por varones. La media de edad – desviación estándar de la muestra era de 22 ± 3,6 años, y la prevalencia de fumadores, del 30,3%. La media de cigarrillos/día del total de la muestra era de 10,5 ± 6,7; en mujeres, de 9,3 ± 6,1, y en varones, de 14,7 ± 7,4, existiendo diferencias estadísticamente significativas. No se encontraron diferencias signifi-cativas al relacionar la práctica de ejercicio con el consumo de tabaco. El 98,8% opina que el consumo de tabaco dismi-nuye el rendimiento físico y el 46,3% quiere dejar de fumar.

La práctica de ejercicio físico durante la adolescencia, incluida dentro de los programas de prevención, podría interferir con los factores de inicio en el consumo de tabaco y contribuir a disminuir la prevalencia de ta-baquismo en la población.

To determine the prevalence of tobacco use among university students who participate in sports activities.

This was a descriptive, cross-sectional study based on a self-administered questionnaire completed by students who participated in activities at a university sports center. The variables studied were age, sex, tobacco use, cigarettes/day, prior history of physical exercise, awareness of the regulations concerning tobacco use in force on the university campus, opinion on the relationship between smoking and reduced physical performance, and desire to quit smoking.

A total of 406 completed questionnaires were received (41.2% of the target population); 71.7% were from women and 28.3% from men. The mean (SD) age of the sample was 22 (3.6) years, and the prevalence of smoking was 30.3%. The mean number of cigarettes smoked per day was 10.5 (6.7) for the sample as a whole, 9.3 (6.1) for women, and 14.7 (7.4) for men; the differences were statistically significant. No significant differences were found with respect to the relationship between exercise and tobacco use. A total of 98.8% of the subjects were of the opinion that smoking reduced physical performance, and 46.3% expressed a desire to quit.

The practice of physical exercise during adolescence as part of a prevention program might interfere with the factors that lead young people to start smoking and thereby contribute to a reduction in the prevalence of tobacco use in the population as a whole.
