Adolescentes Argentina – Uso de redes sociales, sueño y somnolencia: base recodificada (12–18 años)

This dataset is a recoded version of the publicly available data from Pérez-Chada et al. ("Screen use, sleep duration, daytime somnolence, and academic performance in school-aged adolescents", Mendeley Data / PLOS ONE). It includes 1,257 adolescents aged 12–18 years from urban and suburban schools in Argentina, with variables on age, sex, daily social media and screen use, school-night sleep duration, and daytime sleepiness (Pediatric Daytime Sleepiness Scale). Age groups (12–13, 14–15, 16–18) and categories of social media use (0–1, 1–3, 3–5, >5 h/day) were derived to facilitate age-stratified analyses of the association between social media exposure and sleep outcomes. No simulated values were added; all data come from the original observational study, only recoded and anonymized for secondary analysis. Variables included: id, edad, grupo_edad, sexo, horas_redes_dia, categoria_uso_redes, duracion_sueno_horas, sueno_corto, somnolencia_diurna.
