Chile tiene una de las tasas de obesidad más altas del mundo. Se estima que para el año 2030 las muertes atribuidas a esta enfermedad alcanzarían a 204 mil personas, incrementándose además los costos económicos asociados a esta patología. Las causas y los factores de riesgo asociados al desarrollo de obesidad son diversos. Sin embargo, existe consenso que una de las maneras más eficaces de prevenir y/o disminuir su prevalencia es abordando los factores de riesgo modificables, a través del fomento de hábitos de vida saludable con un enfoque integral, centrados en la alimentación saludable, práctica de actividad física, prevención del tabaquismo y consumo de alcohol, como también en el cuidado de la salud mental del individuo. No obstante, el desafío es cómo hacer realidad estos buenos propósitos. En este contexto, el objetivo de esta revisión, parte 2, fue investigar los principales factores modificables, con énfasis en los factores individuales, que han repercutido en el desarrollo de obesidad: desde una mirada global hasta el caso particular de Chile.
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.

RESUMEN La obesidad es una enfermedad inflamatoria, crónica, recurrente, progresiva y de etiología multifactorial, que afecta a más 650 millones de personas en el mundo. La carga física, emocional y económica que genera la obesidad no solo guarda relación con sus manifestaciones clínicas, sino también por su impacto a nivel sistémico y a largo plazo. En Chile, el crecimiento económico, la urbanización y la globalización han modificado profundamente el modo de vivir de la población lo que ha favorecido un ambiente obesogénico. Sin embargo, ¿qué factores han repercutido en el desarrollo de obesidad en Chile? ¿cuál ha sido el rol de cada uno de estos factores en el aumento de la prevalencia de esta patología? En la parte 1 de esta revisión discutiremos los principales factores no modificables que han repercutido en su desarrollo, desde la transición epidemiológica que vivió el país en la década de los 70, hasta las patologías endocrinas relacionadas.
Certain countries have the privilege of diverse ecosystems that allow access to wide food availability. This fact carries an intrinsic diversity in bioactive compounds such as phytochemicals, especially polyphenols.The aim of this review is to summarize the advances in polyphenols research which have been conducted in Chile, with a focus on polyphenol-rich foods and health-related outcomes. In the first part, several studies that have analyzed food sources rich in polyphenols are presented. This is followed by a description of in vitro and in vivo studies from Chile that have evaluated the polyphenol compounds of Chilean foods or their extracts along with their biological activity or health effects. Most polyphenol studies in our search have an in vitro experimental design where mainly protective activities are tested. The antioxidant effect is remarkable in all studies. As well as discussing the future direction of dietary assessment and the approach to biomarkers in this field, currently, additional emphasis and research investment are necessary to explore more native foods with an added value.

Aim: To investigate the association between asthma and adiposity markers in Chilean adults. Material and Methods: Data from 5,499 adults older than 15-years-old from the Chilean National Health Survey 2016-2017 were analyzed. Quintiles of body-mass index (BMI) and waist circumference (WC) were used as a proxy of adiposity. The association between asthma and quintiles of BMI and WC was determined by logistic regression. Results: A higher BMI and WC was associated with a higher odds for asthma. This trend remained significant even after adjusting the models for socio-demographic factors, physical activity and smoking (Odds Ratio [OR] BMI: 1.13 [95% confidence intervals (CI): 1.04; 1.22], p < 0.01 and OR WC: 1.15 [95% IC: 1.06; 1.25], p < 0.01). Conclusions: A higher BMI and WC were positively associated with asthma. (Rev Med Chile 2019; 147: 733-740)
