RESUMEN
Introducción: La alimentación se construye a partir de experiencias y significados adquiridos en el curso de la vida. Las personas mayores tienen un acervo importante que informa de valores y prácticas culturales aplicadas a la alimentación. El objetivo del estudio fue interpretar los significados que entregan personas mayores a la construcción de su alimentación en trayectorias del curso de vida. Métodos: La investigación utilizó un enfoque cualitativo de alcance exploratorio, utilizando el método de teoría fundamentada de Strauss y Corbin. Para la recolección de datos se aplicó una entrevista semiestructurada entre julio de 2021 y junio de 2022. El tipo de muestreo fue teórico y el análisis de los datos cualitativos respondió al proceso de codificación abierta, axial y selectiva. Resultados: Participaron 54 personas mayores (72% mujeres) con edad promedio de 68,6 años (6,9 años). Las personas mayores construyeron su alimentación con un alto significado a las comidas caseras, con influencia de género femenino durante la niñez y adolescencia. En la adultez, se reconstruye la alimentación al ingresar al mundo laboral. En la actualidad, cimentan la alimentación con un enfoque de cuidados para su salud. Reconocen transiciones y puntos de inflexión en la alimentación provocados por terremotos, pandemia por COVID-19, situación política en el país, embarazos o el diagnóstico de alguna enfermedad crónica. Discusión: Las personas mayores reconocen diversas vivencias en trayectorias vitales que han marcado sus patrones alimentarios. Estas experiencias de vida pueden ser la base de estrategias o acciones en la práctica clínica que aporten a su bienestar.
Introduction: Food is intricately woven into the fabric of our experiences and the meanings accumulated throughout life. Older people possess a rich cultural heritage that shapes the values and practices surrounding food.The aim of the study was to interpret the meanings attributed to older people to the construction of their feeding in life course trajectories. Methods: The research employed a qualitative exploratory approach, utilizing the Grounded Theory method developed by Strauss and Corbin. Data collection took place through semi-structured interviews conducted between July 2021 and June 2022. The sampling method employed was theoretical, and the analysis of qualitative data followed the open, axial, and selective coding process. Results: A total of 54 older individuals (72% women), with an average age of 68.6 years (6,9 years), participated in the study. These individuals constructed their relationship with food, assigning significant value to homemade meals, influenced by gender roles during childhood and adolescence. In adulthood, the relationship with food transformed with entry into the workforce. Currently, their feeding are guided by a health-centric approach. They recognize transitions and turning pointsin food provoked by earthquakes, pandemic by COVID-19, political situation in the country, pregnancies or the diagnosis of a chronic disease. Discussion: Older people recognize a multitude of life experiences that have left imprints on their eating patterns. These life experiences can be the basis for strategies or actions in clinical practice that contribute to their well-being.
RESUMEN
Introducción. Las masculinidades representan roles sociales diversos y un estereotipo masculino que limita el desarrollo de tareas domésticas, entre otras, el estar a cargo de la alimentación familiar. Objetivo. Interpretar los relatos de personas mayores sobre el rol de las masculinidades en la transmisión alimentaria familiar. Materiales y Métodos. Estudio exploratorio con enfoque cualitativo utilizando la metodología de la Teoría Fundamentada de Strauss y Corbin. Participaron personas mayores de género masculino, a los que se les aplicó entrevista semiestructurada. Los datos fueron analizados a través de codificación abierta, axial y selectiva, lo que permitió identificar las categorías centrales que fueron la base del levantamiento de teoría que responde al objeto de estudio. La investigación fue avalada por comité de ética científica. Resultados. Se reconoce una cesión social de hábitos, patrones y costumbres alimentarias familiares en este grupo de personas, en especial, en etapas nóveles de su trayectoria vital. Como personas mayores, las masculinidades se adaptan a los cuidados y necesidades de sus respectivos hogares, ayudando en las compras de alimentos, elaborando preparaciones culinarias o reconociendo miembros masculinos de sus familias en el traspaso intergeneracional de saberes alimentarios. Conclusión. Desde los relatos de personas mayores participantes, las masculinidades presentan una dinámica familiar que comienza a desmitificar el rol de género femenino en el traspaso cultural de la alimentación.
Introduction. masculinities represent diverse social roles and a male stereotype that limits the development of domestic tasks, among others, be in charge of family feeding. Objective. to interpret the stories of older people about the role of masculinities in the family food transmission. Material and methods. exploratory study with qualitative approach using the methodology of the Grounded Theory of Strauss and Corbin. Elderly male participants participated, to whom a semi-structured interview was applied. The data were analyzed through open, axial and selective coding, which allowed identifying the central categories that were the basis of the theory survey that responds to the object of study. The research was endorsed by the scientific ethics committee. Results. a social transfer of family eating habits, patterns and customs is recognized in this group of people, especially in the new stages of their life trajectory. As older people, masculinities adapt to the care and needs of their respective homes, in particular, in new stages of their life trajectory. As older people, masculinities adapt to the care and needs of their respective homes, assisting in food purchases, preparing culinary preparations or recognizing male members of their families in the intergenerational transfer of food knowledge. Conclusion. From the stories of elderly participants, masculinities present a family dynamic that begins to demystify the female gender role in the cultural transfer of food.
RESUMEN
OBJECTIVE: To investigate the association between a lifestyle score and all-cause mortality in the Chilean population. DESIGN: Prospective study. SETTINGS: The score was based on seven modifiable behaviours: salt intake, fruit and vegetable intake, alcohol consumption, sleep duration, smoking, physical activity and sedentary behaviours. 1-point was assigned for each healthy recommendation. Points were summed to create an unweighted score from 0 (less healthy) to 7 (healthiest). According to their score, participants were then classified into: less healthy (0-2 points), moderately healthy (3-4 points) and the healthiest (5-7 points). Associations between the categories of lifestyle score and all-cause mortality were investigated using Cox proportional hazard models adjusted for confounders. Nonlinear associations were also investigated. PARTICIPANTS: 2706 participants from the Chilean National Health Survey 2009-2010. RESULTS: After a median follow-up of 10·9 years, 286 (10·6 %) participants died. In the maximally adjusted model, and compared with the healthiest participants, those less healthy had 2·55 (95 % CI 1·75, 3·71) times higher mortality risk due to any cause. Similar trends were identified for the moderately healthy group. Moreover, there was a significant trend towards increasing the mortality risk when increasing unhealthy behaviours (hazard ratio model 3: 1·61 (95 % CI 1·34, 1·94)). There was no evidence of nonlinearity between the lifestyle score and all-cause mortality. CONCLUSION: Individuals in the less healthy lifestyle category had higher mortality risk than the healthiest group. Therefore, public health strategies should be implemented to promote adherence to a healthy lifestyle across the Chilean population.

Multimorbidity patterns can lead to differential risks for all-cause mortality. Within the Chilean context, research on morbidity and mortality predominantly emphasizes individual diseases or combinations thereof, rather than specific disease clusters. This study aimed to identify multimorbidity patterns, along with their associations with mortality, within a representative sample of the Chilean population. 3,701 participants aged ≥18 from the Chilean National Health Survey 2009-2010 were included in this prospective study. Multimorbidity patterns were identified from 16 chronic conditions and then classified using latent class analyses. All-cause mortality data were extracted from the Chilean Civil Registry. The association of classes with all-cause mortality was carried out using Cox proportional regression models, adjusting by sociodemographic and lifestyle variables. Three classes were identified: a) Class 1, the healthiest (72.1%); b) Class 2, the depression/cardiovascular disease/cancer class (17.5%); and c) Class 3, hypertension/chronic kidney disease class (10.4%). Classes 2 and 3 showed higher mortality risk than the healthiest class. After adjusting, Class 2 showed 45% higher mortality risk, and Class 3 98% higher mortality risk, compared with the healthiest class. Hypertension appeared to be a critical underlying factor of all-cause morbidity. Particular combinations of chronic diseases have a higher excess risk of mortality than others.

Objetivo: Elaborar un modelo de co-construcción de cápsulas comunicacionales intergeneracionales para difundir preparaciones culinarias significativas de personas mayores. Material y métodos: El estudio se enmarca en la investigación aplicada del tipo tecnológico. Se realizó una búsqueda teórica de aspectos relevantes en el uso de cápsulas comunicacionales (videos), así como el uso de TICs en personas mayores, siguiendo los lineamentos del diseño cualitativo a través de un análisis de contenido temático. Luego se construye un modelo, que es validado por profesionales del área gerontológica, para ser aplicado en un proyecto piloto que incluyó a una diada constituida por una persona mayor y un descendiente, los que guiaron y grabaron una entrevista en profundidad focalizada. Resultados: Se co-construyeron 6 videos con preparaciones culinarias tradicionales en el que participaron 5 mujeres y 1 hombre, de las Regiones del Biobío y Metropolitana. Se siguió modelo teórico que incorporó 7 pasos para su elaboración: identificación de diada intergeneracional, capacitación, realización del video, primera edición del video, presentación del video a la diada, edición final y difusión del video en redes sociales. Conclusiones: Como estrategia para un envejecimiento saludable, la realización de un video intergeneracional con una receta preferida se visualiza como una oportunidad para entrelazar cultura, patrimonio y emociones entre los participantes y la comunidad.
Introduction: The appreciation of traditional foods is essential in the maintenance of gastronomic heritage; however, its dissemination is limited, which is why communication strategies are required to promote the dissemination of intangible cultures. Objective: To develop a model for the co-construction of intergenerational communication capsules that allow the dissemination of significant culinary preparations for the elderly. Material and methods: The study is part of an applied technological research. In order to consolidate knowledge and use it for educational purposes, a theoretical search of relevant aspects in the use of communication capsules (videos) was carried out, following the guidelines of qualitative design through thematic content analysis. Then, a model is constructed and validated by professionals from the gerontological area to be applied to a pilot project that included a dyad made up of an elderly person and a descendant, who guided and recorded an in-depth focused interview. Results: A total of 6 videos about traditional culinary preparations made by 5 women and 1 man from the Biobío and Metropolitana Regions were co-constructed. A theoretical model that incorporated 7 steps for its elaboration was followed: identification of intergenerational dyad, training, making of the video, first edition of the video, presentation of the video to the dyad, final edition, and dissemination of the video on social networks. Conclusions: As a strategy for healthy aging, making an intergenerational video with a favorite recipe is seen as an opportunity to intertwine culture, heritage and emotions between participants and the community.
RESUMEN
ANTECEDENTES: Tanto el gen FTO (Fat-mass and obesity-associated-gene) y el tiempo sedente se asocian a obesidad, sin embargo, se desconoce si el tiempo sedente puede modificar la predisposición genética a la obesidad. Por ende, el objetivo de este estudio fue investigar si la asociación entre el polimorfismo rs9939609 del gen FTO y marcadores de adiposidad podrían ser modificados por el tiempo sedente. MÉTODOS: Este estudio de corte transversal incluye a 409 participantes del estudio GENADIO. Los marcadores de adiposidad estudiados fueron peso corporal, índice de masa corporal (IMC), perímetro de cintura (PC) y porcentaje masa grasa. El tiempo sedente se determinó mediante acelerometría de movimiento. La interacción entre el gen FTO (rs9939609) y el tiempo sedente sobre los marcadores de adiposidad se determinó mediante análisis de regresión múltiple. RESULTADOS: Tanto la variante de riesgo del gen FTO como el tiempo sedente se asociaron a mayor peso corporal, IMC, PC y masa grasa. Sin embargo, la asociación entre tiempo sedente y marcadores de adiposidad fue mayor en personas portadoras del alelo de riesgo del gen FTO. Por cada 1 hora de incremento en tiempo sedente, el peso corporal incrementa en 1,36 kg ([95% IC: 0,27; 2,46], p = 0,015) y 2,95 kg ([95% IC: 1,24; 4,65], p = 0,001) en personas con la variante protectora (TT) versus aquellos con la variante de riesgo (AA), respectivamente. Resultados similares se encontraron para (PC). CONCLUSIÓN: La asociación entre la variante de riesgo de FTO y mayor nivel de adiposidad es más acentuada en individuos que presentan mayores niveles de sedentarismo.
BACKGROUND: The Fat-mass and obesity-associated-gene (FTO gene) and sedentary behavior time are associated with obesity. However, whether sedentary behavior time can modify the genetic predisposition to obesity in the Chilean population is unknown. Therefore, this study investigated the association between sedentary behavior, adiposity markers, and the FTO gene. METHODS: This cross-sectional study included 409 participants from the Genes, Environment, Diabetes, and Obesity (GENADIO) study. Adiposity markers studied included body weight, body mass index (BMI), waist circumference (WC), and fat mass. Sedentary behaviors were measured using accelerometers. Using multiple regression, we evaluated the interaction between sedentary behaviors and the FTO gene (rs9939609) on adiposity markers. RESULTS: Sedentary behaviors and the FTO genotype were positively associated with higher body weight, BMI, WC, and fat mass. However, the association between time of sedentary behavior and adiposity markers was higher in carriers of the risk variant for the FTO gene. For each hour of increment in sedentary behaviors, body weight increases by 1.36 kg ([95% CI: 0.27; 2.46], p = 0.015) and 2.95 kg ([95%CI: 1.24; 4.65], p = 0.001) in non-risk carriers (TT) versus risk carriers (AA), respectively. We observed similar results for WC, BMI, and body fat, but the interaction was significant only for WC. CONCLUSION: The association between sedentary behaviors and adiposity markers, especially body weight and WC, is higher in individuals who carry the risk variant of the FTO gene.

INTRODUCCIÓN: El nuevo índice de obesidad basado en el volumen corporal (ABSI) ha sido asociado con enfermedades crónicas no transmisibles y mortalidad, independientemente de los valores del índice de masa corporal (IMC); sin embargo, se desconoce su asociación con diabetes mellitus tipo 2 (DMT2) en población chilena. OBJETIVO: determinar la asociación entre ABSI con glicemia, hemoglobina glicosilada (HbAc1) y DMT2 en población adulta chilena. MATERIALES Y MÉTODOS: Estudio transversal, incluyó a 4.874 participantes (edad media 43,3 años, 50,9% mujeres) de la Encuesta Nacional de Salud 2016-2017. ABSI fue calculado según la fórmula propuesta (basado en circunferencia de cintura, IMC y estatura. La Regresión de Poisson fue utilizada para investigar la asociación entre ABSI con DMT2 y regresión lineal para glicemia y HbAc1. Los análisis se ajustaron según factores sociodemográficos, de estilos de vida e IMC. RESULTADOS: ABSI fue positivamente asociado con glicemia (p < 0,001), HbA1c (p < 0,001) y DMT2 (p < 0,001). En el modelo más ajustado, por cada 0.025 unidad de aumento de ABSI, la glicemia aumentó en 1,78 mg/dL (95% IC: 1,21; 2,35) y la HbAc1en un 0,92% (95% IC: 0,49; 1,35). En cuanto a DMT2, la razón de prevalencia fue de 1,14 (95% IC: 1,09; 1,20), independiente de factores sociodemográficos, estilos de vida e IMC. CONCLUSIONES: ABSI se asoció de forma lineal con una mayor probabilidad de padecer DMT2, mayores niveles de glicemia y HbA1c en adultos chilenos. En este contexto, ABSI podría ser un índice complementario, independiente del IMC, para evaluar el riesgo de alteraciones metabólicas asociadas a obesidad.
INTRODUCTION: A Body Shape Index (ABSI) is a new obesity index based on body volume; this has been associated with chronic non-communicable diseases and mortality, independent of the values of the body mass index (BMI); however, its association with type 2 diabetes mellitus (T2DM) in the Chilean adult population is unknown. OBJECTIVE: To determine the association between ABSI, glycemia, glycosylated hemoglobin (HbAc1), and self-reported T2DM in the Chilean adult population. MATERIALS AND METHODS: In a cross-sectional study, 4,874 participants were included (mean age 43.3 years, 50.9% women) from the 2016-2017 National Health Survey. ABSI was calculated according to the proposed formula (based on waist circumference, BMI, and height). The Poisson regression was used to investigate the association between ABSI and T2DM, and linear regression was used to investigate the association between ABSI, glycemia, and HbAc1. Sociodemographic factors, lifestyle, and BMI adjusted the analyses. RESULTS: ABSI was positively associated with glycemia (p < 0.001), HbA1c (p < 0.001), and DMT2 (p < 0.001). In the most adjusted model, for every 0.025 unit increase in ABSI, glycemia increased by 1.78 mg/dL (95% CI: 1.21, 2.35) and HbAc1 by 0.92% (95% CI: 0.49, 1.35). Regarding T2DM, the prevalence ratio was 1.14 (95% CI: 1.09, 1.20), independent of sociodemographic factors, lifestyles, and BMI. CONCLUSIONS: ABSI was linearly associated with a higher probability of suffering from T2DM and higher levels of glycemia and HbA1c in Chilean adults. In this context, ABSI could be a complementary index, independent of BMI, to assess the risk of metabolic disorders associated with obesity.

OBJECTIVE: To identify the association between oral health and suspected cognitive impairment in older adults in Chile. METHOD: Cross-sectional study including 1826 people ≥60 years who participated in the National Health Survey of Chile, 2016-2017. Oral health was evaluated by the number of teeth, presence of caries, use of dental prostheses, self-reported oral health, and pain and/or discomfort in the oral cavity. Cognitive impairment was assessed using the Mini-Mental State Examination (MMSE). The association was evaluated by logistic and linear regression, adjusted for sociodemographic and lifestyle variables. RESULTS: Compared with people without suspicion of cognitive impairment, people with suspected impairment had five fewer teeth (13.4 vs. 8.5 teeth), a much higher difference in women than in men, and a higher frequency of oral pain. Edentulism and fewer teeth were associated with a higher likelihood of suspected cognitive impairment, associations that were not maintained in adjusted models. Oral pain was associated with a higher likelihood of suspected impairment even in the most adjusted model (odds ratio: 1.99; 95% confidence interval [95%CI]: 1.09-3.63). In linear models, an increase of 2% (95%CI: 0.01-0.05) in the MMSE score was observed for each additional tooth. CONCLUSIONS: Poor oral health, particularly tooth loss and the presence of pain, was associated with cognitive impairment in older adults in Chile.

INTRODUCTION: Recent studies have shown that low vitamin D levels constitute a potential risk factor for the development of cognitive impairment. The present study aimed to investigate the association between vitamin D levels and the suspicion of cognitive impairment in Chilean older adults. MATERIAL AND METHOD: We performed a cross-sectional study, including 1,287 participants ≥ 65 years (56.8% were women, age range 65 to 97 years) from the Chilean National Health Survey. Cognitive impairment was assessed using the Mini Mental State Examination (MMSE). Participants were classified into three groups according to their vitamin D levels (> 29 ng/ml sufficient, 12-29 ng/ml deficit, and < 12 ng/ml severe deficit). The association between vitamin D levels and cognitive impairment was explored using logistic regression analysis, adjusted for confounding factors. RESULTS: The prevalence of vitamin D deficit and vitamin D severe deficit was 37.7% and 21.0%, respectively. Compared to older adults with sufficient levels of vitamin D, those with severe deficits had a 94% (OR: 1.94 [95% IC: 1.27; 1.66], p = 0.002) higher odds of cognitive impairment (unadjusted model). Adjusting according to sociodemographic factors, lifestyle, adiposity, sunlight exposure, and multimorbidity slightly attenuated the association to 61% (OR: 1.61 [95%IC: 1.03; 2.19], p = 0.046), but remain significant. CONCLUSION: A severe deficit of vitamin D was associated with higher odds of cognitive impairment in Chilean older adults independent of major confounding factors. Future studies are needed to provide causal evidence between vitamin D and the suspicion of cognitive impairment.

La adopción de formas de consumo y producción sostenibles de alimentos es una necesidad imperiosa, debido a las consecuencias adversas que los sistemas alimentarios actuales tienen para la salud y el planeta. A pesar de que estudios muestran que las personas valoran un menor efecto de la dieta en el ambiente, desconocen cómo evaluar su impacto en este sentido. Esta revisión cualitativa buscó la existencia de indicadores o herramientas que permitan evaluar la sustentabilidad de preparaciones culinarias como parte de una dieta sostenible. Se incluyen definiciones, abordajes y formas de medir y evaluar tanto la dieta como la gastronomía sustentable a nivel mundial y nacional. La búsqueda de artículos científicos se realizó en las bases de datos Medline/PubMed, Scopus, Web of Science y SciELO utilizando como palabras claves "dietas sustentables", "dietas sostenibles", "ecogastronomía", "sustainability assessment", "out of home meals", "sustainable gastronomy", "sustainable diet", "sustainable healthy diets", "sustainability indicators", "sustainable indicators", "sustainability index", "sustainable diets index", "dietas sustentáveis". Toda dieta tiene un impacto en el medio ambiente, sin embargo, factores como su composición y formas de producción determinan la magnitud de dicho impacto. Un tema central gira en torno a las metodologías para medir, analizar y evaluar los diferentes aspectos que componen la sostenibilidad de las dietas, existiendo escasa evidencia respecto de herramientas que permitan calificar las preparaciones culinarias según su nivel de sustentabilidad. Por esto, se requiere mayor investigación en la materia con el propósito de contribuir en la adopción de dietas saludables y sostenibles por parte de la población.
The adoption of sustainable forms of consumption and production is an imminent need due to the adverse consequences that current food systems have on health and the planet. Although studies show that people value a lesser effect of diet on the environment, they do not know how to evaluate its impact in this sense. This qualitative literature review investigated the existence of indicators or tools to assess the sustainability of culinary preparations as part of a sustainable diet. Definitions, approaches, and ways of measuring and evaluating sustainable diets and sustainable gastronomy at the global and national levels were included. The search for scientific articles was carried out in the Medline/PubMed, Scopus, Web of Science and SciELO databases using as keywords "sustainable diets", "sustainable diets", "ecogastronomy", "sustainability assessment", "out of home meals", "sustainable gastronomy", "sustainable diet", "sustainable healthy diets", "sustainability indicators", "sustainable indicators", "sustainability index", "sustainable diets index", "dietas sustentáveis". Every diet has an impact on the environment, however, factors such as its composition and forms of production determine the magnitude of this impact. A central issue revolves around the methodologies to measure, analyze and evaluate the different aspects that make up the sustainability of diets, and there is little evidence regarding tools to qualify culinary preparations according to their level of sustainability. Therefore, further research is required in this area in order to contribute to the adoption of healthy and sustainable diets by the population.

INTRODUCTION: A Body Shape Index (ABSI) is a new obesity index based on body volume; this has been associated with chronic non-communicable diseases and mortality, independent of the values of the body mass index (BMI); however, its association with type 2 diabetes mellitus (T2DM) in the Chilean adult population is unknown. OBJECTIVE: To determine the association between ABSI, glycemia, glycosylated hemoglobin (HbAc1), and self-reported T2DM in the Chilean adult population. MATERIALS AND METHODS: In a cross-sectional study, 4,874 participants were included (mean age 43.3 years, 50.9% women) from the 2016-2017 National Health Survey. ABSI was calculated according to the proposed formula (based on waist circumference, BMI, and height). The Poisson regression was used to investigate the association between ABSI and T2DM, and linear regression was used to investigate the association between ABSI, glycemia, and HbAc1. Sociodemographic factors, lifestyle, and BMI adjusted the analyses. RESULTS: ABSI was positively associated with glycemia (p < 0.001), HbA1c (p < 0.001), and DMT2 (p < 0.001). In the most adjusted model, for every 0.025 unit increase in ABSI, glycemia increased by 1.78 mg/dL (95% CI: 1.21, 2.35) and HbAc1 by 0.92% (95% CI: 0.49, 1.35). Regarding T2DM, the prevalence ratio was 1.14 (95% CI: 1.09, 1.20), independent of sociodemographic factors, lifestyles, and BMI. CONCLUSIONS: ABSI was linearly associated with a higher probability of suffering from T2DM and higher levels of glycemia and HbA1c in Chilean adults. In this context, ABSI could be a complementary index, independent of BMI, to assess the risk of metabolic disorders associated with obesity.

Objetivo: Determinar la asociación entre velocidad de la marcha y sospecha de deterioro cognitivo en población mayor chilena. Métodos: Se incluyeron 1788 personas mayores de la Encuesta Nacional de Salud (ENS) 2016-2017 que tenían información sobre velocidad de marcha y sospecha de deterioro cognitivo. La velocidad de la marcha fue autorreportada y categorizada como marca lenta, normal y rápida. Sospecha de deterioro cognitivo fue evaluado a través del cuestionario Mini Mental abreviado. La asociación entre marcha y deterioro cognitivo fue investigada mediante análisis de regresión logística. Resultados: En comparación a las personas mayores que reportaron una velocidad de marcha rápida, aquellas que reportaron una marcha lenta presentaron 2,67 veces mayor probabilidad de tener deterioro cognitivo (OR: 2,67 [95% IC:1,62; 4,42], p<0,001). Al ajustar los modelos por variables de confusión sociodemográficas, estilos de vida y salud, la asociación disminuyó, pero, permaneció significativa (OR: 1,78 [95% IC:1,15; 3,17], p=0,047). Mientras que las personas mayores que reportaron tener una velocidad de marcha normal no presentaron asociación con deterioro cognitivo. Conclusión: Personas mayores que reportan una velocidad de marcha lenta presentaron una mayor probabilidad de sospecha de deterioro cognitivo. Considerando que el deterioro cognitivo es un síndrome geriátrico con alta prevalencia en población mayor, existe la necesidad de enfatizar en estrategias para un diagnóstico temprano, por lo cual la velocidad de marcha podría ser un instrumento útil.
Background: Walking pace could be considered an early risk marker of cognitive impairment in older people. Objective: To determine the association between walking pace and cognitive impairment in older Chilean adults. Methods: 1,788 adults older than 60 years from the 2016-2017 Chilean National Health Survey with data available in the exposure and outcome were included in this cross-sectional study. Walking pace was self-reported and categorised as slow, average and brisk. Cognitive impairment was assessed using the Abbreviated Mini-Mental questionnaire. Logistic regression analyses were performed to investigate the association between walking pace and cognitive impairment, logistic regression analyses - adjusted for sociodemographic, lifestyle and health-related covariates. Results: In the minimally adjusted model and compared to older adults who self-reported a brisk walking pace, those in the slow walking pace category were 2.67 times more likely to have cognitive impairment (OR: 2.67 [95% CI: 1.62, 4.42]). When the analyses were adjusted, the association was attenuated but remained significant (OR: 1.78 [95% CI: 1.15 3.17]). No associations were found between average pace walkers and cognitive impairment. Conclusion: Older adults who self-reported a slow walking pace having a higher likelihood of cognitive impairment than their counterparts who had a brisk walking pace. Considering that cognitive impairment is a geriatric syndrome with a high prevalence in the elderly, there is a need to emphasise strategies for an early diagnosis. Therefore, walking pace may be a useful marker to identify individuals at high risk of cognitive impairment.
RESUMEN
BACKGROUND: A low education level has been associated with cognitive impairment in older adults. AIM: To determine the association between educational attainment and suspicion of cognitive imparirment in older Chilean population. MATERIAL AND METHODS: Data from 2,005 adults aged ≥ 60 years assessed during 2016-2017 Chilean National Health Survey were included. Education was self-reported and categorized as primary: ≤ 8 years; secondary: 9 to 12 years and beyond secondary: > 12 years. suspicion of cognitive imparirment was assessed with the Mini-Mental questionnaire. RESULTS: Men and women with low education attainment had a higher prevalence of cognitive impairment (33% [95% confidence intervals (CI): 24; 41] and 27% [95% CI: 21; 33], respectively). Men who reported less schooling (≤ 8 years) were more likely to be at risk of suspicion of cognitive imparirment (Odds ratio (OR): 4.53 [95% CI: 1.10, 18.62]) compared to their peers. Women showed a substantially higher magnitude of association than men. The probability of suspicion of cognitive imparirment increased 9-times (OR: 9.96 [95% CI: 1.24; 79.6]) for 9-12 years and 18-times for ≤ 8 years of education (OR: 18.8 [95% CI: 2.42; 146.1]) compared to women with higher education. CONCLUSIONS: Older adults with low education attainment had an increased likelihood of developing suspicion of cognitive imparirment. However, the risk differs by sex, being higher in women than men.

El incremento de la malnutrición por exceso fundamenta la necesidad de revalorar el rol de los ambientes alimentarios en el bienestar y la seguridad alimentaria de la población. La presente revisión bibliográfica tiene como objetivo realizar una búsqueda descriptiva de los ambientes alimentarios y de cómo estos condicionan los estados de malnutrición por exceso y la seguridad alimentaria de la población. A través de una indagación narrativa en motores de búsqueda y bases de datos (Medline, Scielo, Scopus, Biblioteca Virtual de Salud, Medes y Google Académico), se identificaron artículos originales o revisiones en castellano e inglés publicadas entre los años 2017 al 2021 que respondieron a los propósitos del estudio. Se incluyeron 56 artículos, los cuales permitieron profundizar en las cinco categorías teóricas: ambiente alimentario institucional y organizacional, de restauración, vía pública, abastecimiento y domiciliario; así como en el modo en que estos entornos potencian la malnutrición por exceso y tensionan la seguridad alimentaria de la población. Los distintos ambientes o entornos alimentarios direccionan los estilos de vida y el bienestar de las personas y comunidades, además de influir en la etiología y mantención de la malnutrición por exceso y la seguridad alimentaria de la población.
The increase in malnutrition due to excess supports the need to reassess the role of food environments in the well-being and food security of the population. The objective of this bibliographic review is to carry out a descriptive search of food environments and how these condition states of malnutrition due to excess and the food security of the population. Through a narrative investigation in search engines and databases (Medline, Scielo, Scopus, Virtual Health Library, Medes and Google Scholar), original articles or reviews in Spanish and English published between 2017 and 2021 were identified, served the purposes of the study. 56 articles were included, which allowed to study in more detail the five theoretical categories: institutional and organizational food environment, restoration, public thoroughfare, supply and home; as well as in the way in which these environments enhance malnutrition due to excess and put pressure on the food security of the population. The different environments or food environments direct the lifestyles and well-being of people and communities, in addition to influencing the etiology and maintenance of malnutrition due to excess and the food security of the population.
RESUMEN
This research aimed (1) to examine the agreement between body mass index (BMI)-based nutritional status and perceived nutritional status overall and by socio-demographic factors and (2) to state the association between the accuracy of weight perception and weight control practices in the Chilean adult population. A population-based cross-sectional study was carried out with 5,192 Chilean adult participants from the Chilean National Health Survey 2016-2017. Agreement between BMI-based weight status and body weight perception for the total sample and across subgroups was determined using the weighted kappa coefficient. The agreement between BMI-based and perceived nutritional status of the total sample was fair (kappa = 0.38). A higher rate of weight perception accuracy was identified in women, younger respondents, and participants with higher education, a higher income, and from urban areas than their counterparts. Respondents with overweight or obesity tended to underestimate their nutritional status. Actions to lose weight were higher in those who had the right perception of their overweight/obesity condition and those who overestimated their body weight, regardless of their nutritional status. In all groups, weight loss behaviors were more related to the perceived than the BMI-based nutritional status. The consequences of accurate perception of the nutritional status are discussed including its effects on body weight and mental health.
RESUMEN
BACKGROUND: The adaptation of older people to nursing homes may be problematic. Scales to assess the degree of adaptation are required. AIM: To adapt and evaluate the psychometric characteristics of the Scale of Adaptation of the Older Adults to their Residence (EAPAR) in the Chilean population. MATERIAL AND METHODS: EAPAR and self-esteem scales were applied to 106 people aged 79 ± 7 years (57% women) living in nursing homes. Reliability was measured using Cronbach's alpha. RESULTS: The instrument was adequately understood by the Chilean participants. In the content validity, the structure of the scale appears homogeneous and with an acceptable statistical significance. CONCLUSIONS: EAPAR is a reliable and valid instrument to be used by health professionals.

Resumen: Objetivo: El aislamiento social originado por el COVID-19 ha potenciado modificaciones en los estilos de vida, afectando el bienestar de las personas mayores. Es por esto que el objetivo del estudio es el interpretar las influencias de factores emocionales y socioeconómicos en las preferencias alimentarias de personas mayores en Gran Concepción, Chile, en tiempos de pandemia. Materiales y Métodos: Para el logro de los propósitos, se realizó una investigación que responde al paradigma cualitativo con enfoque fenomenológico interpretativo de Heidegger. Los participantes existieron seleccionados mediante un muestreo intencional en base a los criterios de selección y considerando como tamaño muestras el resultante del punto de saturación. El estudio incluyó a un total de 12 personas mayores, las que fueron entrevistadas de manera virtual; los datos resultantes, se codificaron, reagruparon y analizaron mediante técnica de análisis de contenido. Resultados: Los platillos preferidos responden a los propios de la cultura local; por otra parte, aspectos emocionales y económicos no son reconocidos en la selección de alimentos y preferencias alimentarias. La comunicación lograda por el uso de redes sociales con sus familias es identificada como positiva y no influye en sus conductas alimentarias. Conclusiones: Para este grupo de personas mayores, la vivencia de aislamiento social por COVID-19, no fue suficiente para modificar las preferencias alimentarias.
Abstract: Objective: The social isolation caused by COVID-19 has promoted changes in lifestyles, affecting the well-being of the elderly. Therefore, the objective of the study is to interpret the influence of emotional and socioeconomic factors in food preferences of older people of the Gran Concepcion, Chile, in times of pandemic. Materials and methods: For the achievement of its purposes, an investigation was carried out that responds to the qualitative paradigm with the interpretive phenomenological approach of Heidegger. Participants were selected by intentional sampling based on the selection criteria and considering the sample size resulting from the saturation point. The study included a total of 12 elderly, who were interviewed virtually; the resulting data was coded, regrouped and analyzed using a content analysis technique. Results: The favorite dishes respond to those of the local culture; on the other hand, emotional and economic aspects are not recognized in the selection of food and food preferences. The communication achieved using social networks with their families is identified as positive and does not influence their eating behaviors. Conclusions: For this group of older people, the experience of social isolation due to COVID-19 was not enough to modify food preferences.
RESUMEN
RESUMEN Introducción: La fuerza de prensión manual permite evaluar debilidad muscular en personas mayores y presenta correlación con la fuerza general y masa muscular, por lo que podría ayudar en la detección precoz del deterioro de la función física y riesgo de caídas. Objetivo: Relacionar la fuerza de prensión manual con la función física y riesgo de caídas en personas mayores. Métodos: Estudio descriptivo, correlacional. Evaluó 87 personas mayores (24 hombres y 63 mujeres) entre 65 y 75 años, de 4 organizaciones sociales de Talca, Chile, seleccionados por un muestreo no probabilístico por conveniencia. Para medir la fuerza de prensión manual se utilizó́ un dinamómetro de mano, para valorar la función física se usó la prueba Short Physical Performance Battery; con las pruebas de estación unipodal y time up and go se evaluó riesgo de caídas. Resultados: Se observaron relaciones significativas moderadas entre la fuerza de prensión manual y el test Short Physical Performance Battery (p= 0,001; r= 0,473) y con todas las pruebas que componen esta batería. Se evidenció una relación entre la fuerza de prensión y la prueba de estación unipodal (p= 0,001; r= 0,472), mientras que la relación con la prueba time up and go fue inversa débil (p= 0,002; r= -0,398). Conclusión: Existe relación entre la fuerza de prensión manual con la función física y el riesgo de caídas personas mayores. Este hallazgo sugiere que la fuerza de prensión manual podría usarse en la práctica clínica como instrumento de detección precoz de la pérdida de la función física y riesgo de caídas.
ABSTRACT Introduction: Handgrip strength is a way to evaluate muscle weakness in older people and it has been seen to show a high correlation with general strength and body muscle mass, which is why it could help in the early detection of deterioration in physical function. loss of lower limb strength and risk of falls. Objective: To relate handgrip strength with physical function and risk of falls in older people. Methods: Descriptive, correlational study. It evaluated 87 older people (24 men and 63 women) between 65 and 75 years old, from 4 social organizations in the city of Talca, Chile, selected through a non-probabilistic convenience sampling. To measure the handgrip strength, a hand dynamometer was used, to assess physical function the Short Physical Performance Battery test was used, and the unipodal station and time up and go tests were used to evaluate balance static and dynamic respectively. Results: Moderately significant relationships were observed between the handgrip strength in the Short Physical Performance Battery test (p = 0.001; r = 0.473) and with all the tests that make up this battery. A moderate one was also evidenced between the grip strength and the unipodal station test (p = 0.001; r= 0.472), while the relationship with the time up and go test was weak inverse (p = 0.002; r = -0.398). Conclusion: There is a relationship between handgrip strength with physical function and the risk of falls in older people. This finding is important because it suggests that handgrip strength could be used in clinical practice as an indirect indicator or as an early detection tool for loss of general strength capacity, physical fitness, and risk of falls.
