RESUMO
Resumen Antecedentes: se observa un aumento creciente en la prevalencia de sobrepeso y obesidad en la población infantil y se multiplican iniciativas para su prevención y control. Objetivo: caracterizar las intervenciones en obesidad infantil publicadas en literatura científica reciente. Materiales y Métodos: se realizó una revisión sistemática de investigaciones empíricas cuantitativas sobre intervenciones en obesidad infantil, en las bases de datos Web of Science, Scopus y Scielo entre los años 2013 y 2019. Se seleccionaron 30 artículos que describían 30 intervenciones distintas. Resultados: las intervenciones se centraron en promover una alimentación saludable y ejercicio físico, con énfasis en la reducción del peso corporal y medidas antropométricas como principales variables de resultado. La duración se concentró entre los 4 y 6 meses y se desarrollaron mayoritariamente en contextos escolares. Conclusiones: los estudios coinciden en la importancia de abordar la problemática a un nivel individual, grupal y comunitario, y cautelar la pertinencia de las intervenciones en función de la especificidad social y cultural del grupo objetivo. Persisten desafíos en relación con el diseño de intervenciones fundamentadas teóricamente, promover la adherencia a los programas y extender periodos de seguimiento para conocer su efectividad en el largo plazo.
Abstract Background: There is a growing increase in the prevalence of overweight and obesity in the child population and initiatives for their prevention and control are multiplying. Objective: To characterize the interventions in child obesity published in recent scientific literature. Materials and Methods: A systematic review of quantitative empirical research on interventions in child obesity was carried out in the Web of Science, Scopus and Scielo databases between the years 2013 and 2019. A total of 30 articles describing 30 different interventions were selected. Results: The interventions were mainly focused on promoting a healthy diet and physical exercise, with an emphasis on reducing body weight and anthropometric measures as the main outcome variables. The duration was concentrated between 4 and 6 months and they were developed mainly in school contexts. Conclusions: The studies agree on the importance of addressing the problem at an individual, group and community level and ensuring the relevance of the interventions based on the social and cultural specificity of the target group. Challenges persist in relation to the design of theoretically-based interventions, promoting adherence to programs, and extending follow-up periods to determine their long-term effectiveness.

RESUMO
OBJECTIVE: To analyze the relationship between anxiety, self-esteem, happiness index and primary school students' academic performance in Chilean adolescents from the Biobío province. METHODOLOGY: 733 (46.1% girls; 12 (1.3 years)) public primary school students that completed the 2018 Health and School Performance Survey carried out in the Biobío province were included in this cross-sectional analysis. The BECK Anxiety Inventory (BAI) was used to measure anxiety while happiness index and self-esteem were measured using the subjective happiness scale and the Rosenberg self-esteem scale, respectively. School performance was measured by grade point average (GPA) of language, math, physical education and cumulative GPA, and behavior associated with cognition in the school context was also considered. The relationship between mental health indicators and school performance was investigated using a one-way ANOVA and Pearson correlation. RESULTS: In comparison to students with low anxiety levels and high self-esteem and happiness levels, students with higher anxiety levels, lower self-esteem and happiness levels perceived themselves as having memory problems. They were also slower to solve math problems, had a shorter attention span in class and presented more difficulties in solving complex tasks, as well as being more nervous during testing. These students also got the lowest grade point average in math, language and physical education. CONCLUSIONS: High anxiety levels, low self-esteem and low happiness levels were associated with lower school performance and weaker behavior associated with cognition in Chilean adolescents. Implementing plans of emotional education and mental health could improve academic achievement.
