| Abstract (English): | High blood pressure in school-aged children is an emerging public health problem associated with preventable factors such as physical inactivity, poor diet, and low levels of self-care. However, evidence on comprehensive interventions that simultaneously address these factors in schoolchildren is still scarce, especially in Latin American contexts. The objective of this study was to evaluate the effectiveness of a comprehensive educational intervention in cardiovascular health, based on high-intensity interval training (HIIT) and self-care practices, in students in the city of Osorno, Chile. A quasi-experimental design without a control group was used, developed between March and June 2024. Forty-six students between the ages of 9 and 12 participated, belonging to four public schools selected through proportional stratified sampling. The intervention included twelve HIIT sessions led by a physical education professional, along with recreational and educational activities on self-care, facilitated by nurses and nutritionists addressing topics such as hygiene, healthy eating, hydration, and sleep. Blood pressure and bilateral grip strength were measured before and after the intervention. The results showed a statistically significant decrease in systolic and diastolic blood pressure (p < 0.001), with moderate effect sizes. An increase in bilateral grip strength was also observed. These findings suggest that the implementation of integrated educational strategies in schools can effectively contribute to the improvement of cardiometabolic indicators and the promotion of healthy lifestyles from an early age, favoring overall well-being and the prevention of chronic diseases.

| Abstract (Spanish): | Introducción: La hipertensión arterial en edad escolar constituye un problema emergente de salud pública, asociado a factores prevenibles como el sedentarismo, la alimentación inadecuada y el bajo nivel de autocuidado. Sin embargo, la evidencia sobre intervenciones integrales que aborden simultáneamente estos factores en escolares es aún escasa, especialmente en contextos latinoamericanos. Objetivo: Evaluar la efectividad de una intervención educativa integral en salud cardiovascular, basada en entrenamiento físico de alta intensidad intermitente (HIIT) y prácticas de autocuidado, en estudiantes de la ciudad de Osorno, Chile. Metodología: Se empleó un diseño cuasiexperimental sin grupo control, desarrollado entre marzo y junio del 2024. Participaron 46 estudiantes entre 9 y 12 años, pertenecientes a cuatro escuelas públicas seleccionadas mediante muestreo estratificado proporcional. La intervención incluyó doce sesiones de HIIT dirigidas por un profesional de Educación Física, junto a actividades lúdico-educativas sobre autocuidado, facilitadas por enfermeras y nutricionista abordando temáticas como higiene, alimentación saludable, hidratación y sueño. Se midieron la presión arterial y la fuerza prensil bilateral antes y después de la intervención. Resultados: Los resultados mostraron una disminución estadísticamente significativa en la presión arterial sistólica y diastólica (p < 0.001), con tamaños de efecto moderado. También se observó un aumento en la fuerza prensil bilateral. Conclusión: Estos hallazgos sugieren que la implementación de estrategias educativas integradas en el ámbito escolar puede contribuir efectivamente a la mejora de indicadores cardiometabólicos y a la promoción de estilos de vida saludables desde edades tempranas, favoreciendo el bienestar integral y la prevención de enfermedades crónicas.

Foram realizadas medições de pressão arterial e força de preensão manual bilateral antes e após a intervenção. Os resultados mostraram uma redução estatisticamente significativa na pressão arterial sistólica e diastólica (p < 0,001), com tamanhos de efeito moderados. Também foi observado um aumento na força de preensão bilateral. Esses achados sugerem que a implementação de estratégias educativas integradas no ambiente escolar pode contribuir de forma eficaz para a melhoria de indicadores cardiometabólicos e para a promoção de estilos de vida saudáveis desde a infância, favorecendo o bem-estar integral e a prevenção de doenças crônicas.
