Objetivo: Determinar la autoestima y los trastornos alimenticios en estudiantes de bachillerato de Ciencias del Colegio “Técnico Salesiano” Cuenca, 2025 – 2026. Metodología: Se utilizó el método observacional, con enfoque cuantitativo, analítico y de corte transversal, se identificó a 224 estudiantes de bachillerato de Ciencias del Colegio “Técnico Salesiano”. Se aplicó dos instrumentos: Escala de autoestima de Rosenberg y Cuestionario EAT-26, usando los programas IBM SPSS 27. Para la asociación se utilizó chi-cuadrado (𝑋2), y valor p <0.05. Los resultados son presentados en tabla simple de doble entrada. Resultados: De 224 estudiantes de bachillerato de Ciencias que participaron, el 20,98% posee riesgo de presentar TCA y el 3,1% presentan autoestima media, el 96,88% autoestima baja; además, se identificó que no existe una relación estadísticamente significativa entre la autoestima y los TCA ya que presenta un valor p 0,658.

Objective: To determine self-esteem and eating disorders in high school students of Science at the “Salesian Technical” School Cuenca, 2025 – 2026. Methodology: The observational method was used, with a quantitative, analytical and cross-sectional approach, 224 high school students of Sciences of the “Salesian Technical” School were identified. Two instruments were applied: Rosenberg Self-Esteem Scale and EAT-26 Questionnaire, using IBM SPSS 27 programs. Chi-square (𝑋2), and a P-value <0.05 were used for the association. The results are presented in a single, double-entry table. Results: Of 224 school science students who participated, 20.98% were at risk of presenting EDs and 3.1% had medium selfesteem, 96.88% had low self-esteem; in addition, it was identified that there is no statistically significant relationship between self-esteem and EDs since it has a p-value of 0.658.
