ABSTRACT
Antecedentes: La velocidad de la marcha podría considerarse un marcador temprano de riesgo de deterioro cognitivo en personas mayores. 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.
ABSTRACT
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.

RESUMEN Chile es uno de los países de Latinoamérica que exhibe un mayor envejecimiento poblacional, por lo que es necesario visualizar distintas herramientas que direccionen estilos de vida saludables en esta etapa de la trayectoria vital. Las Guías Alimentarias Basadas en Alimentos (GABA) entregan recomendaciones que permiten mejorar la calidad de vida de personas mayores. Por lo anterior, el objetivo del estudio fue determinar el nivel de cumplimiento de recomendaciones de las GABA y su asociación con variables antropométricas, metabólicas y de estilos de vida en 1.789 personas mayores de 60 años que participaron en la Encuesta Nacional de Salud 2016-2017. Se realizó un estudio descriptivo de corte transversal, en donde los participantes se subdividieron en cuatro grupos según cumplimiento de las GABA: no cumple, cumple con 1, 2 o a lo menos 3 recomendaciones de consumo de legumbres, frutas y verduras, lácteos, agua y pescado. Como resultado, el 43,8% de las personas mayores que participaron no cumplieron ninguna de las recomendaciones GABA evaluadas; estos últimos, realizaban menos actividad física y presentaban, además, una mayor probabilidad de pasar más tiempo sentados (p-tendencia: <0,001). Como conclusión, se destaca que cerca del 50% de las personas mayores en Chile no adhieren a las recomendaciones de las GABA, lo que podría repercutir en implicaciones en la salud y bienestar de la población mayor.
ABSTRACT Chile is one of the Latin American countries that exhibits the greatest increase in the aging population, thus it is necessary to visualize different tools that guide healthy lifestyles at this stage of life. Food-Based Dietary Guidelines (abbreviated as GABA, for initials in Spanish) provide recommendations that allow improving the quality of life in older people. This study aimed to determine the level of compliance with GABA recommendations and their association with anthropometric, metabolic and lifestyles factors in 1,789 people over 60 years who participated in the 2016-2017 National Health Survey. A descriptive cross-sectional study was carried out, in which participants were subdivided into four groups according to compliance with GABA: does not comply, complies with 1, 2 or at least 3 recommendations for consumption of legumes, fruits, vegetables, dairy, water and fish. As a result, 43.8% of older participants did not meet any of the GABA recommendations evaluated. These participants also performed less physical activity and had a longer sitting time (P-trend: <0.001). In conclusion, we highlight that close to 50% of elderly Chileans do not adhere to GABA recommendations, which could have implications for the health and well-being.
ABSTRACT
RESUMEN Introducción: La lactancia materna (LM) es un factor protector contra la obesidad infantil; sin embargo, los mecanismos a través de los cuales ejerce este efecto aún no están claros. El objetivo fue describir los mecanismos asociados al efecto protector que ejerce la lactancia materna contra la obesidad infantil. Métodos: Se utilizaron los buscadores PUBMED, SCOPUS, Cochrane Library y Scielo para desarrollar una revisión descriptiva de la evidencia científica. Las palabras clave fueron: lactancia materna, obesidad, mecanismo y dieta. Se revisaron artículos en español e inglés, desde 1977 hasta el 2020. Resultados: El efecto protector de la LM contra la obesidad infantil está dado por una combinación de varios mecanismos, se destaca su composición nutricional y el aporte de sustancias bioactivas, algunas de ellas reguladoras de la ingesta energética. Los lactantes que reciben LM por más tiempo seleccionan alimentos más saludables en etapa preescolar, independiente de factores sociodemográficos. También han sido descritos efectos en la adiposidad, el control del peso corporal y la ingesta energética mediante regulación de la programación epigenética y de la microbiota intestinal. Conclusión: La LM es un proceso único, que interacciona de forma compleja con factores del crecimiento y desarrollo de los lactantes y preescolares. Su rol protector contra la obesidad ha sido asociado a diversos mecanismos. Sin embargo, se requiere de nuevas investigaciones para comprender los alcances que puede presentar la LM en la etapa pediátrica y su rol en la prevención de la obesidad.
ABSTRACT Background and aim: Breastfeeding (BF) is a protective factor against childhood obesity; however, the mechanisms associated with this effect have not yet been elucidated. This study aimed to describe the mechanisms related to the protective effect of breastfeeding against childhood obesity. Methods: A search on PUBMED, SCOPUS, Cochrane Library and SCIELO databases was carried out to develop a descriptive review of the scientific evidence. The key words were breastfeeding; obesity; mechanism and diet. Articles were reviewed in Spanish and English from 1977 to 2020. Results: The protective effect of BF against childhood obesity is given by a combination of several mechanism. Its nutritional composition and the contribution of bioactive substances stand out, some of them regulated by the energy intake. Infants who are breastfed choose healthier foods in preschool, regardless of sociodemographic factors. Effects on adiposity, control of body weight and energy intake have also been described by epigenetic regulation programming and the intestinal microbiota. Conclusion: BF is a unique process that interacts in a complex way with infants and preschoolers' growth and developmental factors Its protective role against childhood obesity has been associated with various mechanisms. New research is still required to understand the implications of BF in pediatric age and its role in preventing obesity.
ABSTRACT
Las ciencias morfológicas incluyen el estudio de tres disciplinas que analizan el cuerpo humano: la anatomía macroscópica, la histología y la embriología, las cuales forman parte central del ciclo básico en todas las carreras de la salud. El aprendizaje morfológico ocurre en el laboratorio y se basa en el estudio de disecciones cadavéricas, preparaciones histológicas o muestras del desarrollo embrionario, con el propósito de lograr una adecuada compresión de las características morfoestructurales del cuerpo humano. Sin embargo, la pandemia por SARS-CoV-2 significó un cambio profundo en la forma de enseñar, incorporando métodos de enseñanza-aprendizaje utilizados du-rante la pandemia que incluyen estrategias como los microscopios virtuales, atlas interactivos o videos de disecciones, lo que ha llevado a algunos a cuestionar la necesidad de utilizar los laboratorios de morfología. La educación virtual ha aparecido como una alternativa factible de mantener post-pandemia, sin embargo, el paso por el laboratorio es irreemplazable en la formación de profesionales de la salud, permitiendo el desarrollo de otras competencias más allá de la aplicación del conocimiento. La morfología seguirá siendo la piedra angular en la formación de profesionales de la salud. El desafío es como a través de la innovación y la creatividad incorporamos las nuevas tecnologías digitales, agregando un nuevo valor al estudio de esta disciplina.
Morphological sciences include the study of three disciplines that analyze the human body: macroscopic anatomy, histology, and embr-yology, which are a central part of the basic cycle in all health careers. Morphological learning occurs in the laboratory, it is based on the study of cadaveric dissections, histological preparations, or samples of embryonic development to achieve an adequate compression of the morphological structure of the human body. The SARS-CoV-2 pandemic meant a profound change in the way of teaching. These, teaching-learning methods that have been implemented during the pandemic include virtual microscopes, interactive atlases, or videos of dissections, which has led some teachers to question the usefulness of morphology laboratories. Virtual education has appeared as a feasible alternative to maintaining in post-pandemic; however, going through the laboratory is irreplaceable in the training of health professionals, allowing the development of other skills beyond the application of knowledge. The morphology will continue to be the cornerstone in the education of health professionals. The challenge is how through innovation and creativity, we incorporate new digital technologies, adding a new value to the study of this discipline

RESUMEN Antecedentes: Las caídas limitan las actividades de la vida diaria. Actualmente se desconoce cómo los niveles de actividad física (AF) varían luego de sufrir una caída. Objetivo: investigar los niveles de práctica de actividad física de personas mayores que han reportado caídas en los últimos 12 meses. Métodos: Se incluyeron 1.254 participantes ≥ 60 años de Encuesta Nacional de Salud (ENS) 2009-2010. La prevalencia de caídas en los últimos 12 meses se determinó mediante auto reporte. Los niveles de AF y el tiempo sedente se determinaron a través del cuestionario Global Physical Activity Questionnaire (GPAQ). La asociación entre caídas y AF fue investigada mediante regresión lineal. Resultados: El 70,5% [95% IC: 68,0; 72,8] de las personas mayores no reportaron caídas, mientras que un 19,4% [95% IC: 17,4; 21,5] reportó haber sufrido entre 1-2 caídas y un 10% [95% IC: 8,4; 11,8] ≥3 caídas en los últimos 12 meses. En comparación al grupo que reportó no sufrir caídas, aquellos que sufrieron ≥3 caídas realizaban 79,2 minutos menos de AF total/día. Resultados similares fueron observados para AF de transporte y AF moderada. No se encontraron diferencias para tiempo sedente o AF vigorosa. Conclusión: Personas mayores que sufrieron caídas en los últimos 12 meses reportaron realizar menos actividad física que sus contrapartes que no experimentaron caídas. A mediano y largo plazo, estos cambios en la actividad física podrían contribuir a resultados de salud adversos en una población.
ABSTRACT Background: Falls among older adults are associated with important changes in lifestyle. However, there is no evidence about the physical activity levels of older adults who have experienced falls. The aim of this study, therefore, was to describe physical activity levels in older adults who have experienced falls in the last 12 months. Methods: 1,254 older adults (aged ≥60 years) from the National Health Survey 2009-2010 were included in this study. Number of falls during the last 12 months was self-reported and physical activity was measured using the Global Physical Activity Questionnaire (GPAQ). The association between falls and physical activity was investigated using regression analyses. Results: 70.5% [95% CI: 68.0; 72.8] of the older adults included in this study did not report any falls during the last 12 months. However, 19.4% [95% CI: 17.4; 21.5] reported 1-2 falls and 10% [95% CI: 8.4; 11.8] reported ≥3 falls in the last 12 months. In comparison to those who reported no falls, those who experienced ≥3 falls in the last 12 months did 79.2 fewer minutes/day of physical activity. Similar results were found for moderate and transport-related physical activity, but no associations were found for vigorous or sedentary behaviours. Conclusion: Older adults who suffered falls in the last 12 months reported doing less physical activity than their counterparts who did not experience any falls. In the middle and long term, these changes in physical activity could contribute to adverse health outcomes in an already frail population.
ABSTRACT
RESUMEN Fundamento: una intervención basada en ejercicio multicomponente favorecería la funcionalidad. Sin embargo, son escasos los estudios locales, en Chile, que los han utilizado. Objetivo determinar los efectos del ejercicio multicomponente en la disminución del riesgo de caída y riesgo de deterioro cognitivo, la mejora del equilibrio, fuerza muscular, capacidad funcional y calidad de vida en personas mayores que viven en comunidad. Métodos: estudio preexperimental pre-post sin grupo control. La muestra fue intencionada (n=17; 47,1 % mujeres; 70 años de mediana). Se aplicó un plan de ejercicio multicomponente durante nueve semanas. Pre y post ejercicio se evaluó equilibrio dinámico con el test Timed Up and Go, equilibrio estático con un oscilógrafo postural y la prueba de Estación Unipodal, fuerza muscular con el test de Sentarse y Levantarse, capacidad funcional con el test de Marcha 6 Minutos, calidad de vida con el Cuestionario SF-36 y sospecha de deterioro cognitivo con el Mini Mental State. Para determinar diferencias pre-post ejercicio se aplicó la prueba de Wilcoxon. Resultados: después de los ejercicios se observó un mejor rendimiento en las pruebas: Timed Up and Go (p=0,004), Estación Unipodal (p=0,023 pierna derecha, p=0,005 pierna izquierda), Sentarse y Levantarse (p=0,014), Marcha de 6 Minutos (p=0,006) y en el Cuestionario SF-36: dolor corporal (p=0,003), salud mental (p=0,000) y puntaje total (p=0,002). Conclusiones: un programa de ejercicio multicomponente de nueve semanas logró disminuir el riesgo de caídas, mejorar equilibrio, fuerza muscular, capacidad funcional y calidad de vida de personas mayores que viven en comunidad.
ABSTRACT Background: a multicomponent exercise-based intervention would favor functionality. However, there are few local studies, in Chile, that have used them. Objective to determine the effects of multicomponent exercise in reducing the falling and cognitive deterioration risks, improving balance, muscle strength, functional capacity and life quality in elderly people living in the community. Methods: pre-post experimental study without control group. The sample was intentional (n = 17; 47.1% women; median 70 years old). A multicomponent exercise plan was applied for nine weeks. Pre and post exercise, dynamic balance was evaluated with the Timed Up and Go test, static balance with a postural oscillograph and the Unipodal Station test, muscle strength with the Sit and Stand test, functional capacity with the 6 Minute Walk test, quality life with the SF-36 Questionnaire and suspected cognitive impairment with the Mini Mental State. To determine pre-post exercise differences, the Wilcoxon test was applied. Results: after the exercises, a better performance was observed in the tests: Timed Up and Go (p = 0.004), Unipodal Station (p = 0.023 right leg, p = 0.005 left leg), Sitting and Getting up (p = 0.014), 6-Minute Walk (p = 0.006) and in the SF-36 Questionnaire: body pain (p = 0.003), mental health (p = 0.000) and total score (p = 0.002). Conclusions: a nine-week multicomponent exercise program was able to reduce the risk of falls, improve balance, muscle strength, functional capacity and quality of life in older people living in the community.
ABSTRACT
Background: Adiposity and education are two independent risk factors for type 2 diabetes (T2D). However, there is limited evidence whether both education and adiposity are associated with T2D in an additive manner in the Chilean population. Aim: To investigate the joint association between adiposity and education with T2D in the Chilean adult population. Material and Methods: Analysis of data of the Chilean National Health Survey 2016-2017, which included 5,033 participants with a mean age of 43 years, (51% women). Poisson regression analyses with robust standard error were used to investigate the joint association of the education level and general and central adiposity with T2D. The results were reported as Prevalence Ratio and their 95% confidence intervals (PR, 95% CI). Results: Obesity was associated with a higher probability of having T2D in men than in women, however central adiposity was associated with a higher probability of having T2D in women than in men. Compared with men who had higher education (> 12 years) and had normal body weight, those with the same educational level and who were obese had 2.3-times higher probability of having T2D (PR: 2.35 [95% CI: 1.02; 5.39]). For women, having a low education and being obese was associated with 4.4-times higher probability of having T2D compared to those with higher education and normal body mass index (BMI) (PR: 4.47 [95% IC: 2.12; 9.24]). Similar results were observed when waist circumference was used as a marker of obesity rather than BMI. Conclusions: Women and men with higher BMI and low education had a higher risk of T2D. However, this risk was higher in women than in men.

A pesar de que son muchos los suplementos deportivos que se etiquetan como ergogénicos, pocos son los que realmente demuestran su efectividad. Si bien estos suplementos están destinados principalmente para deportistas de élite, su uso se ha masificado en la po-blación general, esto debido a la falta de regulación en uso y venta, así como por los potenciales beneficios que podrían otorgar. Frente a estas limitantes ¿cuál es la efectividad de estos productos más allá de la moda? En esta comunicación breve se revisa la evidencia respecto al efecto y la efectividad de 11 suplementos y plantas utilizados como ayuda ergogénica. A pesar de los múltiples beneficios en los suplementos ergogénicos identificados, es necesario tener precaución al momento de generalizar los resultados obtenidos por algunos ergogénicos, ya que su efecto podría ser secundario y/o estar condicionado por otros factores. Es necesario mayores estudios clínicos que permitan asociar una relación causa-efecto en el rendimiento deportivo y la población general.
Although many sports supplements have been identified as ergogenic, few have demonstrated their effectiveness. They were originally created for high-performance athletes, but their consumption has incremented in the general population. Lack of regulation to sell and use these products is one of the main problems in our society. In this context, what is the effectiveness of ergogenic supplements beyond the trends? In this short communication, 11 ergogenic supplements and plants will be discussed regarding their effect and efficacy. However, considering that their effect could be a side effect of other factors, findings should be analyzed with caution. Further clinical trials are needed to estimate the causal effect in sports performance and the general population.

Background: Water is an essential nutrient for cellular homeostasis and life. Drinking ≥ 6 glasses (1.5 L/day) is the recommendation of daily water intake (RIAD). Aim: To characterize water intake, according to sociodemographic, anthropometric and lifestyles variables, in the Chilean adult population. Material and Methods: Analysis of data from 5,520 participants of the 2016-17 National Health Survey. Compliance with RIAD by population groups according to sociodemographic, anthropometric and lifestyle characteristics was studied through logistic regression analyses. Results: Only 27.8% of the national population met the RIAD. Women, people over than 56 years of age, housewives, retired people, widowers, and non-smokers were less likely to meet the RIAD. The likelihood of not complying with RIAD in these segments of the population ranged from 28% to 62%. Conversely, participants who presented a higher likelihood of meeting RIAD were those who co-habiting, had a medium and higher educational level, followed a diet plan, and those who reported a good health and well-being. The likelihood of meeting with the RIAD for these population groups ranged from 47% to 116%. Conclusions: The likelihood of meeting the RIAD varied according to different sociodemographic, anthropometric, and lifestyle variables. Therefore, public policies for promoting water consumption should be focused on all age groups, but especially in those groups with the highest risk of underconsumption.

Background: Cardiorespiratory fitness is a strong predictor of mortality and chronic diseases. However, its estimation is costly and time consuming which may limit it broad use in population-based studies. Aim: To estimate the cardiorespiratory fitness of the Chilean population by using equations and to characterize fitness levels of the Chilean population by sociodemographic factors. Material and Methods: This cross-sectional study included 5,958 adults from the Chilean Health Survey conducted between 2016 and 2017. Cardiorespiratory fitness was estimated from sex-specific equations for men and women and expressed as METs (Energy Metabolic Equivalent). Fitness levels were characterized by sociodemographics factors (age, sex, education, income and area of residency). Results: Fitness levels were higher in men (9.01 METs) than in women (6.76 METs) and in average decrease by 0.59 and 0.34 METs per each year increment in age for men and women, respectively. Fitness levels were 12.7 METs and 7.8 METs for 20-year-old men and women, respectively. However, fitness levels decreased to 7.8 METs and 4.3 METs in 90-year-old men and women, respectively. Fitness levels were also higher in individuals living in urban setting, those with higher education or income levels and lean individuals. Conclusions: This study reports fitness levels in a nationally representative sample of Chile. Fitness levels were higher in men than women however, its decline with age was more pronounce in men than women.

Background: Handgrip strength is an indicator of frailty in older people. Aim: To determine the prevalence of low handgrip strength in older Chilean adults. Material and Methods: A cross-sectional analysis of 244 individuals aged 60 years or more, participating in the 2016-2017 Chilean National Health Survey, was carried out. Handgrip strength was evaluated by a hand dynamometer and low grip strength was determined as a grip strength ≤ 15 kg and ≤ 27 kg for women and men, respectively. Results: Twenty nine percent of participants had low grip strength. The average grip strength among 60-year-old men and women was 34.7 and 22.1 kg, respectively. These figures decreased to 28.8 kg and 17.2 kg among 90-year-old men and women, respectively. The prevalence of low grip strength in men and women aged 60 years was 18%. In 90-year-old men and women, these figures increased to 79% and 56.3%, respectively. Conclusions: The prevalence of low grip strength increased substantially with age.

Background: The assessment of frailty among older people could help to reduce its social and health burden. Aim: To determine and characterize the prevalence of frailty in Chilean older adults. Material and Methods: We studied 233 participants, aged > 60 years, participating in the Chilean National Health Survey 2016-2017. Frailty was assessed using modified Fried criteria. Thus, people classified as frail should meet at least 3 out of the 5 criteria (low strength, low physical activity, low body mass index, slow walking pace and tiredness). Results: The prevalence of frailty was 10.9% (7.7% for men and 14.1% for women). The prevalence of pre-frailty was 59.0% whereas 30.1% of participants were classified as robust. At the age of 80 years 58 and 62% of men and women were frail, respectively. These figures increased to 90 and 87% at the age of 90 years. The prevalence of pre-frailty increased from 43 to 92.1% among men and from 76% and 78% among women from the ages of 60 to 90 years, respectively. Conclusions: The prevalence of frailty increased markedly with age. It is important to implement prevention strategies to allow an early identification of high-risk individuals.
