Introduction: The present study analyzed the association between bullying and cyberbullying victimization and aggression, and the light and deep sleep-in adolescents. Recent literature, exposes that bullying can negatively affect sleep quality, interfering with physiological processes essential for recovery and emotional well-being. Method: A cross-sectional study was conducted with 985 Andalusian adolescents (10-16 years old), who wore Xiaomi Mi Band 4 bracelets for seven days to record the duration of sleep phases. Validated questionnaires were applied to measure bullying and cyberbullying, and data were collected on age, sex, BMI and moderate-vigorous physical activity level. Multiple linear regressions were used to analyze covariate-adjusted associations. Results: Bullying victimization was significantly associated with worse sleep, both light (β = -7.267; p = .049) and deep (β = -1.479; p = .048). Likewise, greater cyberbullying victimization showed worse deep sleep (β = -5.278; p = .018). No significant associations were found between aggression behaviors in both bullying and cyberbullying and sleep phases. Conclusions: The results indicate that young people who suffer bullying/cyberbullying show significant sleep disturbances. These findings underscore the need for preventive interventions focused on mitigating the consequences of bullying at a young age. Introducción: El presente estudio analizó la asociación entre la victimización y agresión de bullying y cyberbullying, y el de sueño ligero y profundo en adolescentes. La literatura reciente, expone que el acoso puede afectar negativamente la calidad del sueño, interfiriendo en procesos fisiológicos esenciales para la recuperación y el bienestar emocional. Método: Se realizó un estudio transversal con 985 adolescentes andaluces (10-16 años), quienes portaron pulseras Xiaomi Mi Band 4 durante siete días para registrar la duración de las fases de sueño. Se aplicaron cuestionarios validados para medir bullying y cyberbullying, y se recogieron datos sobre edad, sexo, IMC y nivel de actividad física moderada-vigorosa. Se emplearon regresiones lineales múltiples para analizar asociaciones ajustadas por dichas covariables. Resultados: La victimización por bullying se asoció significativamente con peor sueño, tanto ligero (β = −7.267; p = .049) como profundo (β = −1.479; p = .048). Asimismo, una mayor victimización por cyberbullying mostró un peor sueño profundo (β = −5.278; p = .018). No se hallaron asociaciones significativas entre las conductas de agresión, tanto en bullying como en cyberbullying, y las fases del sueño. Conclusiones: Los resultados indican que los jóvenes que sufren bullying/cyberbullying, muestran alteraciones significativas en el sueño. Estos hallazgos subrayan la necesidad de intervenciones preventivas centradas en mitigar las consecuencias del acoso desde la juventud. 2025-09-17T11:35:23Z 2025-09-17T11:35:23Z 2025-07-31 journal article Rusillo-Magdaleno, A., Solas-Martínez, J.
