Abstract: Cardiorespiratory fitness can be assessed by direct, indirect, maximal, and moderate effort, running, cycling, or walking methods. Objective: To predict maximum oxygen consumption (V O2max) from the six-minute walk test in schoolchildren. Patients and Method: 459 students were included, 215 were male and 244 were female, aged 11.9 ± 1.3 years. Basic anthropometry and cardiorespiratory fitness were measured using field tests. Multivariate equations were developed to predict the V O2max using the R® Commander v. 4.2.2 software (p < 0.05). Results: The best model predicting V O2max include distance walked in the six-minute walk test, heart rate recovery, age, height, body weight (V O2max [L-min-1] = - 0.0902 + (- 0.0464 x age) + (0.0002 x distance) + (- 0.0019 x HR) + (0.5843 x height) + (0.0353 x weight), R2 = 0.76; error = 0.25 L-min-1)), and also body mass index (V O2max [L-min-1] = - 0.6152 + (0.0399 x age) + (0.0933 x BMI) + (0.0005 x distance) + (- 0.0022 x HR), R2 = 0.57; error = 0.34 L-min-1)), both with p < 0.001. Conclusions: Cardiorespiratory fitness can be estimated based on basic anthropometry and performance on the six-minute walk test.

Resumen: La aptitud cardiorrespiratoria se puede evaluar con métodos directos, indirectos, de esfuerzo máximo, moderado, por medio de la carrera, bicicleta o caminata. Objetivo: predecir el consumo máximo de oxígeno (V O2máx) a partir de la prueba de caminata de seis minutos en escolares. Pacientes y Método: Participaron 459 estudiantes, 215 hombres y 244 mujeres, edades 11,9 ± 1,3 años, a quienes se les midió antropometría básica y aptitud cardiorrespiratoria con test de campo. Se elaboraron ecuaciones multivariadas para predecir el V O2máx. con el programa R® Commander v. 4.2.2 (p < 0,05). Resultados: Los mejores modelos que predijeron el V O2máx. incorporaron la distancia recorrida en la prueba de caminata de seis minutos, la frecuencia cardíaca de recuperación, edad, estatura, peso corporal (V O2máx. [L-min-1] = - 0,0902 + (-0,0464 x edad) + (0,0002 x distancia) + (-0,0019 x FC) + (0,5843 x estatura) + (0,0353 x peso), R2 = 0,76; error = 0,25 L-min-1)), y también el índice de masa corporal (V O2máx. [L-min-1] = - 0,6152 + (0,0399 x edad) + (0,0933 x IMC) + (0,0005 x distancia) + (- 0,0022 x FC), R2 = 0,57; error = 0,34 L-min-1)) ambos con p < 0,001. Conclusiones: La aptitud cardiorrespiratoria puede ser estimada en base a la antropometría básica y desempeño en la prueba de caminata de seis minutos.

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.

RESUMEN 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.

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.

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.

Resumen Antecedentes: la fragilidad se caracteriza por la pérdida de reservas biológicas y la vulnerabilidad a resultados adversos. Una intervención con efectos beneficiosos sobre la prevención y el manejo de la fragilidad es la práctica regular de actividad física (AF). Objetivo: caracterizar los niveles de AF y tiempo sedente en personas mayores con fragilidad. Metodología: se incluyó a 232 personas mayores de 60 años de la región metropolitana, participantes en la Encuesta Nacional de Salud 2016-2017. La fragilidad se evaluó en base a los criterios de la escala de fenotipos de Fried y el nivel de AF y tiempo sedentario con el cuestionario Global Physical Activity Questionnaire (GPAQ v2). Los niveles de AF según el fenotipo de fragilidad se determinaron con análisis de regresión lineal. Resultados y conclusiones: las personas mayores con fragilidad realizan menos AF total (β = -292,6 min/día [IC 95 %: 399,5; -185,7], p = 0,001), laboral (β = -5821,8 min/día [IC 95 %: 8680,8; -2962,8], p = 0,001), de transporte (β = -68,0 min/día [IC 95 %: -105,4; -30,62], p = 0,001). También se observó menor cantidad de AF moderada (β = -137,7 min/día [IC 95 %: -202,0; -73,5], p = 0,001); vigorosa (β = -43,4 min/día [IC 95 %: -81,6; -5,20], p = 0,026) y mayor tiempo sedente (β = 3,55 hora/día [IC 95 %: -1,97; 5,14 ], p = 0,001). Las personas mayores frágiles presentan niveles más bajos de AF en comparación con sus pares sin fragilidad. Considerando que la población chilena experimentará un aumento en el número de personas mayores, es imprescindible implementar medidas preventivas que permitan retrasar la aparición de la fragilidad, como fomentar la práctica de AF en todos sus niveles.

Abstract Background: fragility is characterized by loss of biological reserves and vulnerability to adverse outcomes. An intervention with beneficial effects on the prevention and management of frailty is the regular practice of physical activity (PA). Objective: to determine the association between levels of PA, sedentary time and frailty in older Chileans by sex. Methodology: 232 people over 60 years of age from the metropolitan region participating in the National Health Survey 2016-2017 were included. Frailty was assessed based on the Fried Phenotype Scale criteria and PA level and sedentary time with the Global Physical Activity Questionnaire (GPAQ v2). The association between levels of PA with the different states of frailty was investigated with linear regression analysis. Results and conclusion: elderly people with frailty have less total PA (β = -292.6 min/day [95 % CI: 399.5; -185.7], p = 0.001), occupational PA (β = -5821.8 min/day [95 % CI: 8680.8, -2962.8], p = 0.001), transportation (β = -68.0 min/day [95 % CI: -105.4, -30.62], p = 0.001). A lower amount of moderate AF was also found (β = -137.7 min/day [95 % CI: -202.0, -73.5], p = 0.001); vigorous (β = -43.4 min/day [95 % CI: -81.6; -5.20], p = 0.026) and longer time seated (β = 3.55 hours/day [95 % CI: - 1.97, 5.14], p = 0.001). Frail older people have lower PA levels compared to their peers without frailty. Considering that the Chilean population will experience an increase in the number of older people, it is essential to implement preventive measures to delay the onset of frailty, such as promoting the practice of PA at all levels

ABSTRACT Motivation is a fundamental element for the practice of physical activity and the feeling of satisfaction with life. However, little is known about the role of such psychological variables in the lifestyle of Chilean university students. This study aimed to analyse the relationship between life satisfaction and the regulations of motivation and to compare such variables by physical activity level and sedentary behaviour of university students. The sample comprised 95 Chilean university students (63.2% female), with a mean age of 20.92 ± 1.98 years. The instruments were the IPAQ, the Satisfaction with Life Scale, and the Behavioural Regulation in Exercise Questionnaire. Descriptive measures, Pearson’s correlation coefficient, and Student’s t-tests were used to analyse the data. The results revealed positive and significant correlations between life satisfaction and intrinsic (r = 0,44), integrated (r = 0,38), and identified (r = 0,41) regulation. Students with high levels of physical activity scored higher for intrinsic, integrated, and identified regulation. Those who reported low sedentary behaviour showed higher identified regulation. Therefore, it is suggested that students’ motivational regulation may differ on some dimensions as those with higher levels of physical activity show more adaptive motivational regulation. Identified regulation also seems to play an important role in decreasing sedentary behaviour.

RESUMO A motivação é elemento fundamental para a prática de atividade física e o sentimento de satisfação com a vida. Contudo, pouco se sabe sobre o papel de tais variáveis psicológicas no estilo de vida de estudantes universitários chilenos. Este estudo teve como objetivos analisar as relações entre a satisfação com a vida e as regulações da motivação, e comparar tais variáveis em função do nível de atividade física e do comportamento sedentário de estudantes universitários. A amostra foi composta por 95 estudantes universitários chilenos (63,2% do gênero feminino), com idade média de 20,92 ± 1,98 anos. Os instrumentos avaliados foram o IPAQ, a Escala de Satisfação com a Vida e o Questionário de Regulação do Comportamento do Exercício. Medidas descritivas, coeficientes de correlação de Pearson e testes t de Student foram utilizados para analisar os dados. Os resultados revelaram correlações positivas e significativas entre satisfação com a vida e regulação intrínseca (r = 0,44), integrada (r = 0,38) e identificada (r = 0,41). Os estudantes com alto nível de atividade física obtiveram maiores pontuações para regulação intrínseca, integrada e identificada. Os indivíduos que reportaram menor comportamento sedentário possuíam maior regulação identificada. Desse modo, sugere-se que a regulação motivacional dos estudantes pode ser diferente em algumas dimensões, sendo que os indivíduos com maior nível de atividade física semanal demonstram regulações motivacionais mais adaptativas. A regulação identificada também parece desempenhar um papel importante para a redução do comportamento sedentário.

Materiales y método: se empleó la sistematización de experiencias y los participantes fueron los mismos investigadores. Se inició con la organización de los materiales, los diarios de campo de los círculos de investigación temática y relatorías de las reuniones del equipo de investigación y de los actores comunitarios. Se siguió con la elaboración de una matriz con la recuperación histórica. Y, finalmente, de las reflexiones grupales, surgieron categorías y relaciones para la construcción teórica de visión de conjunto. Resultados: se presenta la propuesta teórica de la sistematización y los procedimientos para implementarla, orientada por cinco momentos: vivir la experiencia, formular un plan de sistematización, recuperar el proceso vivido, las reflexiones de fondo y los puntos de llegada. Se destacan cuatro rasgos de la sistematización: una investigación creativa; basada en un proceso de construcción colectiva; para aprender de la práctica y construir conocimiento; y como escenario transformador de esta y de quienes la realizaron. Conclusión: la “sistematización de la sistematización” permitió hacer conciencia sobre la propia praxis investigativa. Muestra la comprensión del grupo acerca de la conceptualización y metodología de esta perspectiva investigativa. Trasciende la recopilación y organización de la información del proceso vivido en la medida en que la reconstrucción de la experiencia es una comprensión más amplia que transforma la práctica de los sujetos involucrados.

Abstract Objective: to present the learning of a systematization as a method, for the construction of knowledge based on the experience lived by the researchers of several projects on parenting education in the field of public health carried out in the rural settlement of Granizal, Antioquia, during the period 2013-2019. Materials and method: the systematization of experiences was used and the participants were the researchers. It began with the organization of the materials, the field diaries of the thematic research circles and reports of the meetings of the research team and community actors. It was continued with the elaboration of a matrix with the historical recovery. And, finally, reflections, categories and relationships emerged from the group for the theoretical construction of the overall vision. Results: the theoretical proposal of the systematization and the procedures to implement it are presented, guided by five moments: living the experience, formulating a systematization plan, recovering the lived process, the background reflections and the arrival points. Four features of systematization stand out: creative research; research based on a process of collective construction; learning from practice and building knowledge; and as a transforming scenario of this research and of those who carried it out. Conclusion: the “systematization of the systematization” allowed raising awareness of the research praxis itself. It shows the understanding of the group on conceptualization and methodology of this research perspective. It transcends the collection and organization of the information of the process lived to the extent that the reconstruction of the experience is a broader understanding that transforms the practice of the subjects involved.

Resumen Antecedentes: El consumo máximo de oxígeno es un indicador de la aptitud cardiorrespiratoria. Objetivo: El objetivo fue relacionar y comparar el V̇O2máx. como variable dependiente con la distancia estimada en la prueba de caminata de seis minutos (PC6M) como variable independiente en estudiantes universitarios, a la vez relacionar la distancia (dependiente) con variables demográficas y antropométricas (independientes). Metodología: Estudio cuantitativo, no experimental, transversal, y descriptivo-correlacional en el que participaron 110 estudiantes universitarios. Se midió antropometría básica y signos vitales, y se aplicó un método directo de V̇O2máx. (Test de Bruce) en cinta rodante, luego se estimó la distancia recorrida en PC6M con dos ecuaciones disponibles en la literatura. Diferencias entre hombres y mujeres en las pruebas aplicadas, correlación entre las distancias estimadas con el V̇O2máx. y variables antropométricas, y la prueba de ANOVA de medidas repetidas entre el V̇O2máx. y las distancias estimadas fueron utilizadas con el programa SPSS v.22 (p<0,05). Resultados: Se encontró correlaciones significativas entre el V̇O2máx. y distancias estimadas (p<0,05) en la muestra, en hombres y mujeres, y en algunos casos la distancia se correlacionó con el sexo, la edad, el peso, la estatura y el IMC (p<0,05). Sin embargo, hubo diferencias entre el V̇O2máx. y las distancias estimadas en la PC6M (p<0,001). Conclusiones: El método directo de V̇O2máx. es distinto de las ecuaciones de predicción de distancia, aunque tienen relación significativa.

Resultados: Foram encontradas correlações significativas entre V̇O2 máx. e distâncias estimadas (p<0,05) na amostra, em homens e mulheres, e em alguns casos a distância correlacionada com sexo, idade, peso, altura e IMC (p<0,05). Entretanto, houve diferenças entre V̇O2 máx. e distâncias estimadas em TC6M (p<0,001). Conclusões: O método direto de V̇O2 máx. é diferente das equações de previsão de distância, embora elas tenham relações significativas.

Abstract Background: Maximum oxygen consumption is an indicator of cardiorespiratory fitness. Aim: The purpose was, first, to relate and compare the V̇O2max as the dependent variable with the estimated distance in the six-minute walk test (SMWT) as the independent variable in university students and, secondly, to relate the distance (dependent) with demographic and anthropometric variables (independents). Methodology: A correlational, descriptive, and quantitative study with a non-experimental design was conducted on 110 university students. In the study, basic anthropometry and vital signs were measured. A direct method of V̇O2max (Bruce test) on a treadmill was applied. Then, the distance covered in the SMWT was evaluated with two equations available in the scientific literature. Differences between men and women were measured in the tests, the correlation between the distances estimated with V̇O2max and anthropometric variables, and repeated ANOVA measurement tests between V̇O2max and estimated distance were analyzed with the SPSS v.22 program (p<0.05). Results: Significant correlations were found between V̇O2max and estimated distances (p<0.05) in the total sample, men and women, and in some cases, the distance correlated with gender, age, weight, height, and BMI (p<0.05). However, there were differences between V̇O2max and distances estimated in the SMWT (p<0.001). Conclusions: The V̇O2max measurement method is different from the distance prediction equations, although they have a significant relationship.

Background: Physical activity (PA) practice reduces the adverse effects of COVID-19. PA counseling promotes healthy lifestyles and prevents cardiometabolic diseases. Aim: To assess the trend in cases of PA counseling and the cardiometabolic disease between 2012 and 2019 (before COVID-19) in a southern Chilean region. Material and Methods: Records of Maule Region Health Service for 731.163 men, and 829.097 women aged < 10 to ≥ 65 years were analyzed. The average annual percentage change (AAPC) during the study period and the annual percentage change (APC) during intermediate periods, were calculated. Results: There was a significant decrease in PA counseling in women in the study period (AAPC: −13.6%). In the 2012-2017 period a significant decrease in counseling for total, men and women were observed (APC: −18.1, −16.5 and −19.1%, respectively). Obesity increased significantly in total, men and women in the 2012-2019 period (AAPC: 10.1, 8.5 and 10.7%, respectively). The same trend was observed for hypertension (AAPC: 8.1, 8.5 and 7.6% respectively) and elevated blood glucose (AAPC: 10, 11.5 and 9.6%, respectively). Conclusions: In the study period PA counseling decreased along with an increase in obesity, hypertension and high blood glucose. Increasing PA counseling is a mainstay in the prevention of cardiometabolic diseases and probably to prevent contagion and complement the treatment of COVID-19.

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 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.

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: Melanoma causes 75% of deaths from skin cancer. In 2018, according to GLOBOCAN, 287,723 new melanoma cases were registered, with a mortality of 60,712 cases, which is equivalent to 20% of all incident cases. Alternatives for the treatment of melanoma are based on disease staging and the molecular characteristics of the disease. Objective: To establish a consensus by common agreement of experts and construct suggestions for the diagnosis and management of early-stage melanoma based on evidence and adjusted to the Colombian context. Methods: A multidisciplinary expert consensus was established, wth the participation of 19 clinical oncologists, 2 soft tissue surgeons, 2 dermatologists, 2 pathologists, and 2 radiotherapists, active members of the Colombian Association of Hemato-Oncology (ACHO). This consensus was carried out in four stages: 1) Structuring of 29 questions, which were scored from 1 to 9; 2) Resubmission of non-consensual questions; 3) Analysis and discussion of responses; and 4) Validation of non-consensual responses by nominal consensus. Results: Twenty-nine questions related to the diagnosis and treatment of early-stage melanoma were discussed in order to construct suggestions based on evidence proven by experts, as well as on internationally recognized oncology management guidelines adapted to the Colombian context and reality. Conclusions: Multidisciplinary suggestions are offered for the diagnosis and treatment of early-stage melanoma, which should be considered in order to guide decision-making and homogenize clinical practice according to the Colombian context and the characteristics of the Colombian health care system. This is an academic and non-regulatory document.

Resumen Introducción: El melanoma ocasiona el 75% de las muertes por cáncer de piel. Según GLOBOCAN, en 2018 se presentaron 287.723 casos nuevos de melanoma, con una mortalidad de 60.712 casos, que equivale al 20% del total de los casos incidentes. Las alternativas para el tratamiento del melanoma se fundamentan en la estatificación de la enfermedad, y en las características moleculares de la enfermedad. Objetivo: Consensuar, por común acuerdo de expertos, sugerencias para el diagnóstico y manejo de melanoma temprano basadas en la evidencia y ajustadas al contexto colombiano. Métodos: Se llevó a cabo un consenso de expertos multidisciplinario, constituido por 19 oncólogos clínicos, 2 cirujanos de mama y tejidos blandos, 2 dermatólogos, 2 patólogos y 2 radioterapeutas, miembros activos de la Asociación Colombiana de Hemato Oncología (ACHO). Este consenso se realizó en 4 etapas: 1. Estructuración de 29 preguntas, que se calificaron de 1 a 9. 2. Reenvío de las preguntas no consensuadas. 3. Análisis y discusión de las respuestas. 4. Las respuestas no consensuadas se llevaron a un consenso nominal. Resultados: Se discutieron 29 preguntas relacionadas con el diagnóstico y tratamiento de melanoma temprano, se construyeron sugerencias basadas en evidencia utilizada por los expertos y en guías de manejo de oncología reconocidas internacionalmente, adaptadas al contexto y realidad colombianos. Conclusiones: Se presentan sugerencias multidisciplinarias para el diagnóstico y tratamiento de melanoma temprano, las cuales debe considerarse para orientar la toma de decisiones y homogenizar la práctica clínica de acuerdo al contexto colombiano y a las características propias del sistema de salud del país. Este es un documento académico y no regulatorio.

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 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.

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.

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.
