Association between adiposity levels and cognitive impairment in the Chilean older adult population
Although both obesity and ageing are risk factors for cognitive impairment, there is no evidence in Chile on how obesity levels are associated with cognitive function. Therefore, the aim of the present study was to investigate the association between adiposity levels and cognitive impairment in older Chilean adults. This cross-sectional study includes 1384 participants, over 60 years of age, from the Chilean National Health Survey 2009–2010. Cognitive impairment was evaluated using the Mini-Mental State Examination. BMI and waist circumference (WC) were used as measures of adiposity. Compared with people with a normal BMI, the odds of cognitive impairment were higher in participants who were underweight (OR 4·44; 95 % CI 2·43, 6·45; P < 0·0001), overweight (OR 1·86; 95 % CI 1·06, 2·66; P = 0·031) and obese (OR 2·26; 95 % CI 1·31, 3·21; P = 0·003). The associations were robust after adjustment for confounding variables. Similar results were observed for WC. Low and high levels of adiposity are associated with an increased likelihood of cognitive impairment in older adults in Chile
Estilos de vida y cumplimiento de las Guías Alimentarias Chilenas: resultados de la ENS 2016-2017
[spa] Cumplir las recomendaciones incluidas en las Guías Alimentarias permite un acercamiento hacia un estilo de vida saludable. El objetivo de este estudio fue caracterizar los estilos de vida de la población chilena y su asociación al cumplimiento de 5 recomendaciones de las Guías Alimentarias Basadas en Alimentos (GABA) chilenas. Se utilizaron datos de la Encuesta Nacional de Salud 2016-2017. Los participantes fueron divi- didos en 4 grupos: aquellos que no cumplieron con ninguna recomendación, los que cumplían una, los que cumplían con 2 y los que cumplían con 3 o más recomendaciones saludables, estableciendo a este último como grupo de referencia. El 43,3% de la muestra no cumplió ninguna de las recomendaciones incorporados en esta investigación. De los que cumplían a lo menos 3, el 35,9% presentó un estado nutricional normal, el 38,9% reportó nunca haber fumado y el 82% se auto percibía como saludable. Además, los que cumplían las recomendacio- nes, presentaron niveles más altos de actividad física. Personas que incorporan y aplican las recomendaciones de las GABA, tienden a presentar conductas de vida más saludable. Estrategias comunicacionales efectivas y formativas en educación alimen- taria sobre estas recomendaciones son claves para prevenir el acelerado y temprano crecimiento de las patologías crónicas.

Advances in polyphenol research from Chile: a literature review
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
