RESUMEN
Objetivo. Evaluar la asociación entre el recuento de micronúcleos en células de epitelio bucal y tabaquismo en estudiantes de pregrado de una universidad privada en Ica. Materiales y métodos. Estudio transversal realizado en estudiantes de quienes se obtuvieron células de epitelio bucal y las cuales fueron teñidas con Giemsa para realizar el conteo de micronúcleos en 2000 células por cada muestra, utilizando microscopia de luz visible a un aumento de 100 X. El tabaquismo se valoró por auto reporte y en escala nominal dicotómica (si o no), recolectándose datos sobre la frecuencia y tiempo de consumo de cigarrillos. Resultados. Se evaluaron 129 estudiantes, en los que el 58.1% fueron mujeres y un promedio de edad de 24.9 ± 5.4 años. El 25.6% eran fumadores activos, cuyo recuento promedio de micronúcleos fue de 3.9 ± 2.4, mientras que en los no fumadores de 0.5 ± 1.2. Se encontró una relación directamente proporcional entre presentar tabaquismo y el recuento de micronúcleos (p<0.001). La edad, sexo, número de cigarrillos consumidos y tiempo como fumador no generaron diferencias significativas en el recuento de micronúcleos. Se observó que los estudiantes con tabaquismo presentaron 9.7 veces el riesgo (IC 95%: 4.4 - 21.6) de tener más de 2 micronúcleos/2000 células, ajustado por edad y sexo. Conclusión. El tabaquismo está asociado al recuento de micronúcleos en células de epitelio bucal de estudiantes de una universidad privada en Ica, Perú.
ABSTRACT
Objective. To assess the relationship between micronuclei count in buccal epithelium cells and tobacco use in students from a private college in Ica. Materials and Methods. This is a cross-sectional study that was performed in college students. Samples from their buccal epithelium were obtained, and they were stained with Giemsa aiming to perform micronuclei count in 2000 cells per sample, using light microscopy at 100 X. Tobacco use was obtained by self-reporting and using a nominal dichotomic scale (yes/no), and data were collected with respect to frequency and time consuming cigarettes. Results: One hundred and twenty nine students participated, 58.1% were female and their average age was 24.9 ± 5.4 years. One quarter of all participants (25.6%) were active smokers, and their average micronuclei count was 3.9 ± 2.4, while the count in non-smokers was 0.5 ± 1.2. A directly proportional relationship was found between tobacco use and micronuclei count (p<0.001). Age, sex, number of cigarettes per day and time being a smoker did not generate significant differences in micronuclei counts. It was found that students with marked tobacco use had a 9.7 times (95% CI: 4.4-21.6) higher risk for having more than 2 micronuclei/2000 cells, being this adjusted for age and sex. Conclusion. Tobacco use is associated to micronuclei count in buccal epithelial cells from students in a private college in Ica.
