ABSTRACT

Objective: Explore the association between compliance with recommended consumption (5-a-day) of fruits and vegetables (F&V) with sociodemographic factors of university students of Latin America. Subjects: We conducted an analytical cross-sectional study in which 4,880 university students from 10 Latin American countries completed a self-administered online survey. Methods: F&V consumption and other sociodemographic variables were measured according to a validated survey. Body mass index was self-reported. Ordinal logistic regression models were applied. Results: Regarding the consumption of F&V, 4.7% of men complied with the recommendation, while in women this value reached 7.7%. In the adjusted model, having a normal weight (OR= 0.59; 95% CI 0.44-0.7; p=<0.001), being female (OR= 0.67; 95% CI 0.49-0.89; p=<0.01), being enrolled in a health-related degree program (OR= 0,60; IC95% 0,45-0,78; p<0.001), having professional parents (OR= 0.75; 95% CI 0.60-0.95; p=<0.05) and practicing physical activity (OR= 0.34; 95% CI 0.27-0.42; p=<0.001) were associated with compliance to F&V consumption recommendations. In the analysis by country, physical activity was the variable most associated with F&V consumption. Conclusion: We observed a low consumption of F&V in university students. The variables associated with compliance to the F&V recommendation were being normal weight, female, being enrolled in a health-related degree program, having professional parents, and practicing physical activity, the latter being the most important variable.


Objetivo: Explorar la asociación de la frecuencia de cumplimiento de las recomendaciones de consumo (5 al día) de frutas y verduras (F&V) con factores sociodemográficos de estudiantes universitarios de América Latina. Metodología: Se realizó un estudio transversal analítico con 4.880 estudiantes universitarios de 10 países de América Latina, quienes completaron una encuesta en línea autoadministrada. Se midió el consumo de F&V y otras variables sociodemográficas según una encuesta previamente validada. El índice de masa corporal fue autoinformado. Se aplicaron modelos de regresión logística ordinal. Resultados: En cuanto al consumo de F&V, en los hombres el 4,7% cumple con la recomendación, mientras que en las mujeres este valor alcanza el 7,7%. En el modelo más ajustado, presentar normopeso (OR= 0,59; IC 95% 0,44-0,7; p=<0,001), ser mujer (OR= 0,67; IC 95% 0,49-0,89; p=<0,01), estar matriculado en carrera relacionada con la salud (OR= 0,60; IC95% 0,45-0,78; p<0,001), tener padres profesionales (OR= 0,75; IC 95% 0,60-0,95; p=<0,05) y realizar actividad física (OR= 0,34; IC 95% 0,27-0,42; p=<0,001) fueron las variables asociadas al cumplimiento del consumo de F&V. En el análisis por país, la actividad física fue la variable más asociada al consumo de F&V. Conclusión: Se observa un bajo consumo de F&V en estudiantes universitarios, y entre las variables asociadas al cumplimiento de la recomendación de F&V se encuentran estar normopeso, sexo femenino, estar cursando una carrera relacionada con la salud, tener los padres y la práctica de actividad física, siendo esta última la variable más importante.

ABSTRACT

Introducción: La actividad física y el fitness cardiorrespiratorio (FCR) son factores protectores en el desarrollo de cáncer. Sin embargo, se desconoce el FCR en población chilena diagnosticada con cáncer. Objetivo: Evaluar la asociación que tuvo el FCR entre las personas con y sin diagnóstico de cáncer, y secundariamente comparar la tendencia del FCR según años de diagnóstico de cáncer en población chilena. Método: Se analizaron datos de 5.483 personas de la Encuesta Nacional de Salud 2016-2017 entre 15 y 98 años. El diagnóstico de cáncer (todos los disponibles) se determinó con preguntas estandarizadas, y el FCR se calculó con método abreviado (demografía, antropometría, estilos de vida). Se realizó análisis de regresión lineal ajustado por variables de confusión con el módulo de análisis de muestras complejas del programa STATA v.16 (95% IC, p < 0,05). Resultados: Las personas con algún tipo de diagnóstico de cáncer, versus aquellas sin cáncer, presentaron un menor nivel de FCR (fi: -1,23 [95% IC: -1,52; -0,94]). Al comparar los niveles de FCR según tipo de cáncer, se observaron resultados similares para cáncer colorrectal, de mama y útero (p < 0,001), pero no para cáncer de tiroides (p = 0,253). Hubo menor FCR desde el primer año de diagnóstico de todo tipo de cáncer hasta sobre diez años, aunque no significativo (p = 0,109). Conclusión: Los diagnosticados con cáncer presentaron menor FCR comparado a los no diagnosticados. Además, en las personas con cáncer el FCR disminuye al incrementar los años desde el primer diagnóstico. Sería importante evaluar e incrementar el FCR en pacientes oncológicos.


Introduction: Physical activity and cardiorespiratory fitness (CRF) are protective factors in cancer development. However, the CRF in the Chilean population diagnosed with cancer is unknown. This study aimed to evaluate the association that the CRF had between people with and without a cancer diagnosis and, secondarily, to compare the trend of the CRF according to years of cancer diagnosis in the Chilean population. Methods: Data from 5,483 people from the 2016-2017 National Health Survey between 15 and 98 years old were analyzed. Cancer diagnosis (all available) was determined with standardized questions, and CRF was calculated with an abbreviated method (demographics, anthropometry, lifestyles). Linear regression analysis adjusted for confounding variables was performed with the complex sample analysis module of the STATA v.16 program (95% CI, p < 0.05). Results: People with some cancer diagnosis versus those without cancer had a lower FCR level (ft: -1.23 [95% CI: -1.52; -0.94]). When comparing CRF levels according to cancer type, similar results were observed for colorectal, breast, and uterine cancer (p < 0.001) but not for thyroid cancer (p = 0.253). There was lower CRF from the first year of diagnosis of all types of cancer to over ten years, although not significant (p = 0.109). Conclusions: Those diagnosed with cancer presented lower CRF compared to those not diagnosed. In addition, in people with cancer, the CRF decreased with increasing years since the first diagnosis. It would be essential to evaluate and increase CRF in cancer patients.

ABSTRACT

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.

ABSTRACT

Antecedentes: La velocidad de marcha es un marcador funcional, utilizado como predictor de enfermedades crónicas. Sin embargo, existe escasa evidencia de la asociación entre la velocidad de marcha y obesidad. Objetivo: Investigar la asociación entre la velocidad de marcha auto-reportada y obesidad en población chilena. Métodos: 6.183 participantes entre 15 a 98 años de la Encuesta Nacional de Salud 2016-2017 de Chile fueron incluidos en este estudio transversal. Peso corporal, talla, perímetro de cintura (PC), índice de masa corporal (IMC) e índice cintura/altura (ICA) fueron determinados. Auto-reporte de velocidad de la marcha (normal, lenta, rápida) fue la variable de exposición. La relación entre velocidad de marcha y marcadores de obesidad fue determinada mediante regresión lineal y regresión de Poisson y todos los análisis fueron ajustados en Modelos según factores sociodemográficos y estilos de vida. Resultados: En el modelo más ajustado, quienes reportaron una velocidad de marcha normal y rápida presentaron un menor IMC (p: -1,03, p = 0,017y -1,56p = 0,001, respectivamente), menor PC (p: -2,98, p = 0,004 y -3,64, p = 0,001) e ICA (3: -0,19, p = 0,004 y -0,26 p < 0,0001) respecto a quienes reportaron una marcha lenta. La velocidad de marcha rápida se asoció a una menor probabilidad de tener obesidad y obesidad central. Conclusión: La velocidad de marcha normal y rápida fueron asociadas con menor peso corporal, IMC, PC e ICA. La velocidad de marcha rápida se asoció a una menor probabilidad de obesidad y obesidad central, independiente de factores sociodemográficos y estilos de vida.


Background: Walking Pace is a functional marker, used as a predictor of chronic diseases. However, there is a lack of evidence on the association between walking pace and obesity. Aim: To investigate the association between-self-reported walking pace with obesity in the Chilean adult population. Methods: 6,183 Chilean participants (aged 15 to 98 years) from the Chilean National Health Survey 2016-2017 were included in this cross-sectional study. Weight, height, waist circumference (WC), body mass index (BMI) and waist to height ratio (WHtR) were the outcomes of interest. Self-reported walking pace (slow, average and brisk) was the exposure. The association between walking pace and obesity was determined by linear regression and Poisson regression and all analyses were adjusted in models according to sociodemographic and lifestyle factors. Results: In the most adjusted model, those who reported an average and brisk walking pace had a lower BMI (¡3: -1.03, p = 0.017 and-1.56 p = 0.001), lower WC (3: -2.98, p = 0.004 and -3.64, p = 0.001) and waist to height ratio (3: -0.19, p = 0.004 and -0.26 p < 0.0001) compared to people who reported a slow walking pace. A brisk walkingpace was associated with a lower probability of obesity and central obesity. Conclusion: the average and brisk walkingpace was associated with lower body weight, BMI, waist circumference and waist to height ratio and a brisk walking pace was associated with a lower probability of obesity and central obesity, independently of sociodemographic and lifestyle factors.

ABSTRACT

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.

ABSTRACT

Introducción: El sobrepeso y la obesidad son problemas de salud pública de nivel mundial. Si bien existe información respecto al consumo de alcohol en estudiantes universitarios durante la pandemia, pocos autores han señalado la asociación entre este hábito y el exceso de peso en esta población. El objetivo fue determinar la asociación entre el consumo de alcohol y el exceso de peso en estudiantes universitarios de 10 países de Latinoamérica durante la pandemia por COVID-19. Metodología: Se realizó un estudio transversal y multicéntrico con 4.539 estudiantes universitarios matriculados en diez países de América Latina. Para la valoración del consumo de alcohol se utilizó la pregunta ¿Consumes bebidas alcohólicas? (1 porción 1 vaso de 200 ml). El índice de masa corporal (IMC) se determinó a partir del peso y la altura auto informado. Para determinar si el exceso de peso (IMC ≥25 kg/m2) estaba asociado con el consumo de alcohol, se utilizó un análisis de regresión logística, ajustado por edad, sexo, año de estudio, nivel socioeconómico, actividad física y tabaquismo. Resultados: Entre los estudiantes con estado nutricional normal, un 59,6% no consumía alcohol, mientras entre los que presentaban un exceso de peso era un 55,1%. Los estudiantes que consumían 2 o más porciones de alcohol al día tenían 2,18 veces más riesgo de tener exceso de peso (OR: 2.18 [95% IC: 1,26 a 3,77]), comparado con aquellos que no consumían alcohol. Conclusión: Se observó que aquellos estudiantes que consumieron más alcohol tuvieron más probabilidades de tener exceso de peso.


Introduction: Overweight and obesity are public health problems worldwide. Alcoholic beverages could increase total energy intake causing an increase in body weight. However, few authors have pointed out the association between this habit and excess weight in this population. The objective of this study was to determine the association between alcohol consumption and excess weight in university students from 10 Latin American countries during the COVID-19 pandemic. Methodology: A cross-sectional and multicenter study was carried out with 4,539 university students enrolled in ten Latin American countries. To assess alcohol consumption, the question Do you consume alcoholic beverages? (1 portion 1 glass of 200 ml). Body mass index (BMI) kg/m2 was determined from self-reported weight and height. To determine if excess weight was associated with alcohol consumption, a logistic regression analysis was used, adjusted for age, sex, year of study, socioeconomic level, physical activity, and smoking. Results: Among students with normal nutritional status, 59.6% did not consume alcohol, while among those with a BMI ≥25 kg/m2 it was 55.1%. Students who consumed 2 or more servings of alcohol per day had a 2.18 times greater risk of being overweight (OR: 2.18 [95% CI: 1.26 to 3.77]), compared with those who did not consume alcohol. Conclusion: It was observed that those students who consumed more alcohol were more likely to be overweight.

ABSTRACT

Introducción: La etapa universitaria es un período de modificación en los estilos de vida. Los estudiantes de carreras de pedagogía y de la salud, adicionalmente, asumirán un rol de guías y modelos respecto a conductas saludables hacia sus estudiantes y pacientes respectivamente. Objetivo: Evaluar la relación entre las características antropométricas, la autopercepción del índice de masa corporal (IMC), la condición física y los hábitos alimentarios en estudiantes universitarios de carreras de pedagogía y de la salud. Materiales y método: Estudio descriptivo y correlacional. La muestra fue conformada por 158 estudiantes universitarios (edad, 22,5±2,5 años). Se evaluó las características antropométricas, autopercepción del IMC, condición física y hábitos alimentarios. Resultados: El IMC se correlacionó positivamente con el IMC percibido (r= 0.46, p= 0.012). El perímetro de cintura se correlacionó positivamente con el IMC percibido y la fuerza de prensión manual. El porcentaje de grasa corporal se correlacionó positivamente con el IMC percibido y negativamente con la condición física (potencia, prensión manual y flexibilidad). El área muscular del brazo se correlacionó con el IMC percibido, puntaje de IMC percibido y condición física. Los hábitos alimentarios presentaron una correlación negativa con el IMC percibido, pero no así con las características antropométricas. Conclusión: Los estudiantes universitarios de las carreras de salud y educación con mejor características antropométricas (menor IMC, perímetro de cintura y porcentaje de grasa y mayor área muscular del brazo), presentan una autopercepción mayor del IMC y un mejor rendimiento en las pruebas de condición física.


Introduction: The university stage is a period of modification in lifestyles. Pedagogy and health career students, additionally, will assume the role of guides and models regarding healthy behaviours towards their students and patients, respectively. Objective: To evaluate the relationship between anthropometric characteristics, self-perception of body mass index (BMI), physical condition and eating habits among pedagogy and health career university students. Materials and method: Descriptive and correlational study. The sample consisted of 158 university students (age 22.5 ± 2.5 years). Anthropometric characteristics, self-perception of BMI, physical condition and eating habits were evaluated. Results: BMI was positively correlated with perceived BMI (r= 0.46, p= 0.012). Waist circumference was positively correlated with perceived BMI and handgrip strength. The percentage of body fat was positively correlated with the perceived BMI and negatively with the physical condition (power, handgrip and flexibility). Arm muscle area was correlated with perceived BMI, perceived BMI score, and physical condition. Eating habits were negatively correlated with perceived BMI but not with anthropometric characteristics. Conclusion: University students from health and education careers with better anthropometric characteristics (lower BMI, waist circumference and fat percentage, and greater muscle area of the arm), have a higher self-perception of BMI and better performance in fitness tests physical.

ABSTRACT

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.

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: Cardiorespiratory fitness (CRF) is inversely associated with metabolic diseases and adiposity markers. Aim: To assess the association of CRF with body mass index (BMI), waist circumference (WC) and obesity in a representative sample of the Chilean population. MATERIAL AND METHODS: Data from 5,958 participants in the Chilean National Health Survey 2016-1027 aged 15 years or above were analyzed. CRF was estimated by an equation that included sociodemographic, anthropometric and health-related data and expressed in metabolic equivalent units (METs). The association between CRF and adiposity was assessed using linear and Poisson regression models and the results were presented as Prevalence Ratio (PR). RESULTS: One MET increment in CRF was associated with a 3.27 kg/m2 (95% confidence intervals (CI): -3.35; -3.2) and 4.56 kg/m2 (95% CI: -4.67; -4.46) lower BMI in men and women, respectively. Waist circumference was 6.7 cm [95% CI: -6.98; -6.42] and 9 cm [95% CI: -9.33; -8.67] lower per 1-MET increment in CRF. With one MET increment, the probability of being obese was 34% (PR = 0.66 [95%CI: 0.63; 0.69]) and 36% (PR = 0.64 [95%CI: 0.61; 0.67]) lower in men and women, respectively. The probability of having a central obesity was 26% (PR = 0.74 [95%CI: 0.71; 0.77]) and 30% (PR = 0.70 [95%CI: 0.68; 0.73]) lower in men and women, respectively. Conclusions: A higher estimated CRF was associated with lower adiposity levels and a lower risk of being obese in both men and women. Public health policies aiming to increase physical activity are needed to increase the CRF of the Chilean population.

ABSTRACT

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

BACKGROUND: The Chilean population reports high levels of physical inactivity. The relationship between income level, physical activity (PA) and sedentary behaviors is not well known. AIM: To describe the levels of PA and sedentary time, according to income levels in the Chilean population. MATERIAL AND METHODS: Analysis of data from the Chilean National Health Survey 2016-2017, which included 5,130 participants (52.9% women). The levels of PA and sedentary time were measured by the Global Physical Activity Questionnaire. Income levels were established according to the self-reported income per capita of the households and presented as quintiles. PA levels according to income levels were estimated by linear regression analyses. RESULTS: Transport-related PA was higher in the lowest income quintiles (p = 0.039). There were no trends for income levels and PA domains including moderate, vigorous, total, occupational and leisure PA. The prevalence of leisure and occupational physical inactivities were higher in the lowest quintiles of income. Sitting time was higher in the higher income levels (p < 0.01). CONCLUSIONS: People in the lowest quintile for income spent more time in transport-related PA and less time sitting. However, physical inactivity prevalence during leisure and work time were higher in people with lower income.

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.

ABSTRACT

RESUMEN La práctica regular de actividad física (AF) ha sido asociada a importantes beneficios metabólicos, como también a la disminución del riesgo de desarrollar algunos tipos de cáncer. El objetivo de esta revisión especial es sintetizar la evidencia científica existente sobre la asociación de los niveles de AF y el riesgo de desarrollar cáncer. Esto permitirá una mejor orientación a futuras políticas públicas destinada a aumentar los niveles de AF en la población chilena. Se buscaron los últimos reportes mundiales y nacionales sobre AF y cáncer en conjunto con una búsqueda de artículos científicos en las bases de datos de Pubmed, Web of Sciences, Scopus, Medline, Scielo y Google Scholar utilizando las siguientes palabras claves: "Exercise», «Neoplasms», "Cancer", "Colorectal", "Breast", "Endometrium", "Physical activity", "Exercise", "Sedentary" and "Sports". Esta revisión entrega evidencia sobre la asociación de la AF con un menor riesgo de múltiples tipos de cáncer, incluyendo cáncer colorrectal, mama y endometrio, pero aún se necesita más investigación con relación a la asociación entre AF y otros tipos de cáncer.


ABSTRACT Regular physical activity (PA) has been associated with important metabolic benefits, as well as a decreased risk of developing some types of cancer. The objective of this scoping review is to synthesize the existing scientific evidence on the association of PA levels and the risk of developing cancer. This will allow a better orientation to future public policies aimed at increasing PA levels in the Chilean population. We searched for the latest global and national reports on PA and cancer as well as scientific databases (Pubmed, Web of Sciences, Scopus, Medline, Scielo and Google Scholar) using the following keywords: "exercise", "neoplasms", "cancer", "colorectal", "breast", "endometrium", "physical activity", "exercise", "sedentary lifestyle" and "sports". Our review supports the protective association between PA and a lower risk of several cancers including colorectal, breast and endometrial cancer. However, more research is still needed to elucidate the role of PA on the risk for other common cancers.

ABSTRACT

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.
