RESUMEN
The measurement of isometric muscle torque with hand-held dynamometry is a technique little studied in the pediatric setting for the evaluation of maximal isometric muscle strength. OBJECTIVE: to determine the reliability of hand-held dynamometry to obtain the maximal isometric torque of upper and lower limb muscle groups in Chilean children and adolescents. PATIENTS AND METHODS: Crosssectional study. Seventy-two participants aged between 7 and 15 years were selected from a school in Talca. Maximal isometric torque was recorded in 15 muscle groups of upper and lower limbs through hand-held dynamometry. Intra- and inter-rater evaluation was used, applying the intraclass correlation coefficient (ICC) to determine the reliability of the tests and Bland-Altman plots to evaluate concordance. RESULTS: The results demonstrated good to excellent inter-rater reliability (ICC = 0.850.98) and intra-rater reliability (ICC = 0.87-0.98). Only two groups, hip extensors and abductors, showed good inter-rater reliability (ICC = 0.85 and ICC = 0.88, respectively); and one group, the ankle dorsiflexors, showed good intra-rater reliability (ICC = 0.87). 100% of the tests presented at least 95.8% inter- and intra-rater agreement on the Bland-Altman plots. CONCLUSION: The evaluation of isometric muscle torque using hand-held dynamometry is a reliable procedure for use in different growth periods.

Background and Objectives: Patients at high altitudes with COVID-19 may experience a decrease in their partial oxygen saturation (PO2S) levels. The objective was to assess the association between PO2S and intensive care unit (ICU) stay in patients at high altitudes with COVID-19. Materials and Methods: Clinical records of 69 COVID-19 patients (36% women) admitted to the ICU were analyzed. Median values were considered for intra-group categories ("≤11 days" and ">11 days" in the ICU) and for PO2S height categories ("<90%" and "≥90%"). Logistic regression and linear regression models adjusted for confounding variables were used. Results: Patients with >11 days in the ICU had 84% lower odds of having a PO2S ≥ 90% (OR: 0.16 [CI: 0.02, 0.69], p = 0.005) compared to those with ≤11 days in the ICU. An increase in PO2S by 1% reduced ICU stay by 0.22 days (ß: -0.22 [CI: -0.33, -0.11], p < 0.001), potentially leading to a reduction of up to 1.44 days. Conclusions: PO2S is a crucial factor in estimating ICU stays for COVID-19 patients at high altitudes and serves as an accessible and cost-effective measure. It should be used in infected patients to complement the prognosis of post-pandemic ICU stay.

Objetivos: Describir el nivel de actividad física (AF) de una población privada de libertad masculina a través del Cuestionario Internacional de Actividad Física (IPAQ, International Physical Activity Questionnaire), correlacionando años de condena y rango etario. Material y método: Estudio no experimental transversal y de corte descriptivo en el que se recogieron datos de nivel de AF a través de la versión breve del cuestionario IPAQ. La información se analizó a través de datos estadísticos descriptivos, como media y desviación estándar, además se realizó un análisis inferencial, con p ≥0,05. Resultados: se aplica el cuestionario a una muestra de 100 hombres privados de libertad de la ciudad de Talca, en Chile, agrupados, en una primera instancia, por años de condena y, en una segunda instancia, por rango de edad, donde se obtiene que las personas estudiadas presentan, a pesar del contexto de limitación de movimiento por encarcelamiento, un nivel de AF moderada, siendo la caminata la actividad que genera más unidades de medida del índice metabólico (MET) entre la muestra. No existen diferencias significativas entre los grupos de la muestra estudiados. Discusión: Los evaluados presentan un nivel de AF menor en comparación con personas de la misma condición en otros países, si muestran un mejor nivel al compararse con la población chilena no recluida. La caminata, que a diario realizan los privados de libertad en los patios de cada módulo y los espacios compartidos en el interior del penal, se observa como factor protector ante enfermedades crónicas no transmisibles (ECNT).

Objectives: To describe the level of physical activity of a male prison population measured with the International Physical Activity Questionnaire (IPAQ), correlating years of sentence and age range. Material and method: Non-experimental cross-sectional and descriptive study. The data was collected through the short version IPAQ questionnaire. The data was analyzed through descriptive statistics such as mean and standard deviation, and an inferential analysis was carried out, with a P ≥ 0.05. Results: The questionnaire was applied to a sample of 100 male prisoners from the city of Talca, Chile. They were grouped firstly into years of sentence and then by age range, obtaining a result from the evaluated population that shows moderate level of physical activity despite the context of confinement, in which walking is the activity that generates more METs among the sample. There are no significant differences between the evaluated groups. Discussion: The evaluated population shows a lower level of physical activity than a similar group in other countries, although they show better levels of physical activity when they are compared to the Chilean general public. Walking, which prisoners do every day in the modules and shared spaces in prison, is found to be a protective factor against chronic noncommunicable diseases. (AU)

INTRODUCTION: Cardiopulmonary function is compromised in people with Parkinson's Disease (PD) and might be related with mortality in advanced stages of the disease. Therefore, estimating the peak oxygen uptake (VO2peak) to monitor its progression overtime and to prescribe exercise is important in clinical context. This study aimed at developing a VO2peak prediction model for older adults' patients with PD based on functional tests used in the physiotherapy clinical settings. MATERIAL AND METHODS: Eighteen patients with PD (63.8 ± 6.6 years old) took part in the study. All participants underwent a basic anthropometry, functional tests, fulfilled a physical activity questionnaire (IPAQ-S) and cardiopulmonary exercise testing on a cycle ergometer. Linear regression and distributional assumptions were performed to develop the prediction model. The Bland-Altman plots were applied for the agreement analysis. RESULTS: The best prediction model included gender, age, waist circumference, BMI, IPAQ-S score, and SPPB functional test score (R2 = 0.87; estimation error: 2.19 ml·kg·min-1; p < 0.001). The distribution assumptions showed validity of the model (p > 0.05), the estimation bias showed a mean of 0.0056 and no pair of data were outside the limits of agreement according to the Bland-Altman diagram. CONCLUSIONS: Accessible, simple, and low-cost variables were useful for validly predicting VO2peak in patients with PD.

Fundamentos: la composición corporal, como elemento predictor de posible aparición de enfermedades crónicas no transmisibles (ECNT), brinda información importante para evaluar el riesgo de salud de las personas. En la población privada de libertad, existen distintos factores de riesgo de podrían afectar su condición de salud, entre ellos, la composición corporal. Por lo que este trabajo busca determinar el perfil antropométrico de una población de individuos masculinos privados de libertad. Métodos: estudio no experimental de tipo transversal, de corte descriptivo que pretende caracterizar el perfil antropométrico de 100 individuos privados de libertad de la ciudad de Talca, Chile. La selección de la muestra fue de tipo no probabilística por conveniencia, ya que se escogieron a los evaluados de acuerdo a la accesibilidad que se tenía a ellos. Se utilizó estadística descriptiva e inferencial. Resultados: la población evaluada presentó un IMC catalogado como sobrepeso con valor 25,69 kg/m2. Los individuos evaluados presentaban un peso corporal promedio de 73,2 kilos y un porcentaje de masa grasa de 24,2%; en cuanto al índice cintura-cadera (ICC), todos los grupos evaluados presentaban un valor menor de 1 o de normalidad. Finalmente, el somatotipo observado correspondía a mesomorfo-endomórfico. Conclusiones: Los individuos privados de libertad evaluados presentan variables antropométricas levemente alteradas, pero con valores cercanos a normalidad (IMC; Masa Grasa), con un ICC menor a 1, clasificándose como normal y con un somatotipo que da cuenta de un relativo desarrollo musculo esquelético, de diámetros óseos y articulaciones grandes, con moderada adiposidad relativa.

ABSTRACT For the researchers, physical literacy (AFi) is the objective to be achieved in Physical Education, for seeking competent subjects, capable of adhering to physical activity throughout their lives, with continuous personal, social, affective, and physical development. Quantitative, descriptive-correlational research was carried out, with a non-experimental design and a non-probabilistic sample of 322 subjects, students from 12 to 18 years old from private, public, and subsidized schools in Talca, Chile. The aim was to relate the level of AFi, engagement and perceived emotionality. Data were collected by the Perceived Physical Literacy Instrument (PPLI), Behavioral Engagement Questionnaire (BEQ) and Scale for Mood Assessment (EVEA). A positive relationship was identified with a higher level of physical literacy, higher levels of happiness (r=0.37) and emotional engagement (r=0.54), decreasing the indexes of hostility (r=-0.25) and the private establishments reach the highest levels of anxiety (X̅=3.2). It is concluded that the higher the level of AFi, the greater the commitment and the greater the regulation of emotional factors.
RESUMO A alfabetização física (AFi) é o objetivo para os pesquisadores na Educação Física, buscando sujeitos competentes e capazes de aderir à atividade física ao longo de suas vidas, com desenvolvimento contínuo pessoal, social, afetivo e físico. Esta pesquisa é de natureza quantitativa, descritiva-correlacional, com um desenho não experimental e uma amostra não probabilística de 322 sujeitos, estudantes de 12 a 18 anos de escolas particulares, municipais e subsidiadas na cidade de Talca, Chile. O objetivo foi relacionar o nível de AFi, comprometimento e emocionalidade percebida. Os dados foram coletados por meio do Perceived Physical Literacy Instrument (PPLI), Behavioral Engagement Questionnaire (BEQ) e Escala de Avaliação do Estado de Ânimo (EVEA). Identificou-se uma relação positiva com um maior nível de alfabetização física, maior nível de alegria (r=0,37) e comprometimento emocional (r=0,54), diminuindo os índices de hostilidade (r=-0,25). As escolas particulares atingem os níveis mais altos de ansiedade (X̅=3,2). Conclui-se que um maior nível de AFi está associado a um maior comprometimento e maior regulação dos fatores emocionais.
RESUMEN
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.
RESUMEN
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.
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.

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.

COVID-19 causes cardiovascular and lung problems that can be aggravated by confinement, but the practice of physical activity (PA) could lessen these effects. The objective of this study was to evaluate the association of maximum oxygen consumption (VËO2max) with vaccination and PCR tests in apparently healthy Chilean adults. An observational and cross-sectional study was performed, in which 557 people from south-central Chile participated, who answered an online questionnaire on the control of COVID-19, demographic data, lifestyles, and diagnosis of non-communicable diseases. VËO2max was estimated with an abbreviated method. With respect to the unvaccinated, those who received the first (OR:0.52 [CI:0.29;0.95], p = 0.019) and second vaccine (OR:0.33 [CI:0.18;0.59], p = 0.0001) were less likely to have an increased VËO2max. The first vaccine was inversely associated with VËO2max (mL/kg/min) (ß:−1.68 [CI:−3.06; −0.3], p = 0.017), adjusted for BMI (ß:−1.37 [CI:−2.71; −0.03], p = 0.044) and by demographic variables (ß:−1.82 [CI:−3.18; −0.46], p = 0.009); similarly occur for the second vaccine (ß: between −2.54 and −3.44, p < 0.001) on models with and without adjustment. Having taken a PCR test was not significantly associated with VËO2max (mL/kg/min). It is concluded that vaccination significantly decreased VËO2max, although it did not indicate cause and effect. There is little evidence of this interaction, although the results suggest an association, since VË O2max could prevent and attenuate the contagion symptoms and effects.

OBJECTIVE: To describe baseline characteristics of outpatients with a positive RT-PCR for SARS-CoV-2 and to define whether "red flags" (new-onset fever, dyspnea, and chest pain) can predict clinical worsening during the isolation period. METHODS: This was an epidemiological, observational, descriptive study. Between March and September of 2020, all outpatients who tested positive for SARS-CoV-2 at a tertiary medical center located in Santiago de Chile were included. Demographic variables, comorbidities, red flags, and other symptoms were compiled using follow-up surveys at specific time points. The risk of clinical worsening (hospitalization) and adjusted hazard ratios (HRs) were calculated. RESULTS: A total of 7,108 patients were included. The median age was 38 years (range, 0-101), and 52% were men. At baseline, 77% of the patients reported having characteristic symptoms of SARS-CoV-2 infection. The most prevalent onset symptoms were headache (53%), myalgia (47%), and fever (33%). According to the follow-up surveys, the incidence of symptoms decreased during the isolation period; however, 28% of the patients still presented with symptoms on day 14. The risk of hospitalization for patients with new-onset fever and dyspnea during the follow-up period was HR = 7.43 (95% CI, 3.85-14.3, p<0.01) and HR = 5.27 (95% CI, 1.52-18.30; p < 0.01 for both), respectively. New-onset chest pain showed no association with clinical worsening. CONCLUSIONS: In this sample of outpatients with a recent diagnosis of SARS-CoV-2 infection, a survey-based monitoring of symptoms was useful to identify those at risk of clinical worsening. New-onset fever and dyspnea during the isolation period were considered as red flags associated with clinical worsening and warrants prompt medical evaluation.

Introducción: La cuarentena y el aislamiento social son las medidas más recomendadas por las autoridades de salud con el objetivo de reducir la interacción social entre las personas y disminuir el riesgo de contagio por la COVID-19 en la comunidad. Sin embargo, estas restricciones y limitaciones pueden traer consecuencias en la calidad de vida relacionada con la salud de adultos jóvenes. Objetivo: Comparar la calidad de vida autorreportada entre un entorno sin pandemia vs. un contexto bajo alerta sanitaria por la COVID-19, en adultos jóvenes. Métodos: Estudio retrospectivo; 157 adultos jóvenes (63 mujeres y 94 hombres), de entre 18 y 28 años, respondieron el cuestionario de salud SF-36 en 2 situaciones: contexto sin pandemia (septiembre de 2019) y contexto de pandemia (abril de 2020). El SF-36 incluye 36 preguntas agrupadas en 8 ítems: función física, rol físico, dolor corporal, salud general, vitalidad, función social, rol emocional y salud mental. Resultados: Al comparar las evaluaciones entre los contextos con y sin pandemia, se observó una disminución de la calidad de vida en las dimensiones vitalidad (p = 0,004), función social (p = 0,001), rol emocional (p = 0,001), salud mental (p = 0,003) y salud general (p = 0,001). Las dimensiones más alteradas fueron el rol emocional y la salud general, las cuales disminuyeron un 39,5 por ciento y 21,0 por ciento, respectivamente. Conclusión: La calidad de vida relacionada con la salud de adultos jóvenes se ve disminuida en un contexto de cuarentena por la COVID-19, principalmente, en las dimensiones psicológicas y sociales(AU)
Introduction: Quarantine and social isolation are the actions most recommended by health authorities with the aim of reducing social interaction between people and reducing the risk of COVID-19 infection in the community. However, these restrictions and limitations can have consequences on the health-related quality of life of young adults. Objective: To compare the self-reported quality of life between a pandemic-free environment versus a context of COVID-19 pandemic in young adults. Methods: Retrospective study; 157 young adults (63 women and 94 men) between 18 and 28 years old answered the SF-36 health questionnaire in 2 situations: context without pandemic (September 2019) and context of pandemic (April 2020). The SF-36 includes 36 questions grouped into 8 items: physical function, physical role, body pain, general health, vitality, social function, emotional role, and mental health. Results: When comparing the evaluations between the contexts with and without a pandemic, a decrease in the quality of life was observed in the vitality dimensions (p = 0,004), social function (p = 0,001), emotional role (p = 0,001), health mental (p = 0,003) and general health (p = 0,001). The most altered dimensions were emotional role and general health, which decreased by 39,5 percent and 21,0 percent, respectively. Conclusions: This study determined that the health-related quality of life of young adults is diminished in context of quarantine by COVID-19, mainly in the psychological and social dimensions(AU)

Cardiorespiratory fitness (CRF) provides oxygen to the exercising muscles and is related to body adiposity, with cardiometabolic variables. The aim was to develop reference values and a predictive model of CRF in Chilean adolescents. A total of 741 adolescents of both genders (15.7 years old) participated in a basic anthropometry, performance in the six-minute walk test (SMWT), and in Course Navette was measured. Percentiles were determined for the SMWT, for the VÌO2max, and an equation was developed to estimate it. The validity of the equation was checked using distribution assumptions and the Bland-Altman diagram. The STATA v.14 program was used (p < 0.05). The 50th percentile values for males and females in the SMWT and in the VÌO2max of Course Navette were, respectively, from 607 to 690 and from 630 to 641 m, and from 43.9 to 45 and from 37.5 to 31.5 mlO2·kg·min-1, for the range of 13 to 17 years. For its part, the model to predict VÌO2max incorporated gender, heart rate, height, waist-to-height ratio (WHR), and distance in the SMWT (R2 = 0.62; estimation error = 0.38 LO2·min-1; p <0.001). Reference values can guide physical fitness in Chilean adolescents, and VÌO2max was possible to predict from morphofunctional variables.

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.
RESUMEN
RESUMEN. El objetivo del presente estudio fue analizar la modificación de la conducta de los participantes del Programa Vida Sana, dirigido por el Ministerio de Salud de Chile (MINSAL) en relación a cuatro aspectos asociados al nivel de Actividad Física. Participaron 43 mujeres (entre 15 a 59 años) que ingresaron al programa que se realiza en un Centro de Salud Familiar (CESFAM) de la comuna de Chiguayante. Para el desarrollo del estudio se aplicó el Cuestionario Internacional del Actividad Física (IPAQ) en un pre y post test. El Grupo fue divido en cuatro subgrupos por rango etarios: Adolescentes 14 a 19 años, Jóvenes 20 a 29 años, Adulto-Joven 30 a 39 años y Adultos sobre 40 años. En base a los resultados obtenidos, estos arrojan un aumento significativo de los METS en los diferentes Dominios estudiados de cada categoría. Es decir, la conducta de los participantes, comparándolo con el pre y post test, manifestó un cambio conductual positivo en ellos al finalizar el programa.
ABSTRACT. The aim of this study is to analyze behavior modification of the Healthy Life Program participants, implemented by the Ministry of Health of Chile (MINSAL) related to four aspects associated with Physical Activity. Forty-three women participated (between 15 and 59 years old) who entered the program held in Family Health Center in Chiguayante County.To develop the study, the International Physical Activity Questionnaire (IPAQ) was applied in a pre and post-test. The Group was divided into four subgroups by age range: Adolescents 14 to 19 years, Youth 20 to 29 years, Adult-Youth 30 to 39 years, and Adults over 40 years. Based on the results obtained, these show a significant increase in METS in the different domains studied for each category. In other words, the participants' behavior, compared with the pre and post-test, showed a positive behavioral change.

ABSTRACT Objective: To describe baseline characteristics of outpatients with a positive RT-PCR for SARS-CoV-2 and to define whether "red flags" (new-onset fever, dyspnea, and chest pain) can predict clinical worsening during the isolation period. Methods: This was an epidemiological, observational, descriptive study. Between March and September of 2020, all outpatients who tested positive for SARS-CoV-2 at a tertiary medical center located in Santiago de Chile were included. Demographic variables, comorbidities, red flags, and other symptoms were compiled using follow-up surveys at specific time points. The risk of clinical worsening (hospitalization) and adjusted hazard ratios (HRs) were calculated. Results: A total of 7,108 patients were included. The median age was 38 years (range, 0-101), and 52% were men. At baseline, 77% of the patients reported having characteristic symptoms of SARS-CoV-2 infection. The most prevalent onset symptoms were headache (53%), myalgia (47%), and fever (33%). According to the follow-up surveys, the incidence of symptoms decreased during the isolation period; however, 28% of the patients still presented with symptoms on day 14. The risk of hospitalization for patients with new-onset fever and dyspnea during the follow-up period was HR = 7.43 (95% CI, 3.85-14.3, p<0.01) and HR = 5.27 (95% CI, 1.52-18.30; p < 0.01 for both), respectively. New-onset chest pain showed no association with clinical worsening. Conclusions: In this sample of outpatients with a recent diagnosis of SARS-CoV-2 infection, a survey-based monitoring of symptoms was useful to identify those at risk of clinical worsening. New-onset fever and dyspnea during the isolation period were considered as red flags associated with clinical worsening and warrants prompt medical evaluation.
RESUMO Objetivo: Descrever as características basais de pacientes ambulatoriais com RT-PCR positivo para SARS-CoV-2 e definir se os sintomas de alerta para gravidade (febre, dispneia e dor torácica de início recente) podem prever piora clínica durante o período de isolamento. Métodos: Trata-se de um estudo epidemiológico, observacional e descritivo. Entre março e setembro de 2020, foram incluídos todos os pacientes ambulatoriais com teste positivo para SARS-CoV-2 em um centro médico terciário localizado em Santiago do Chile. Variáveis demográficas, comorbidades, sintomas de alerta para gravidade e outros sintomas foram compilados usando pesquisas de seguimento em intervalos específicos. Também foram calculados o risco de piora clínica (hospitalização) e as razões de risco (RR) ajustadas. Resultados: Foi incluído um total de 7.108 pacientes. A mediana de idade foi de 38 anos (variação: 0-101), e 52% eram homens. No início do estudo, 77% dos pacientes relataram sintomas característicos de infecção por SARS-CoV-2. Os sintomas recentes mais prevalentes foram cefaleia (53%), mialgia (47%) e febre (33%). De acordo com as pesquisas de seguimento, a incidência de sintomas diminuiu durante o período de isolamento; no entanto, 28% dos pacientes ainda apresentavam sintomas no dia 14. O risco de hospitalização para pacientes com febre e dispneia de início recente durante o período de seguimento foi RR = 7,43 (IC95%: 3,85-14,3; p < 0,01) e RR = 5,27 (IC95%: 1,52-18,30; p < 0,01 para ambos), respectivamente. A dor torácica de início recente não mostrou associação com a piora clínica. Conclusões: Nesta amostra de pacientes ambulatoriais com um diagnóstico recente de infecção por SARS-CoV-2, um monitoramento dos sintomas baseado em pesquisa foi útil para identificar aqueles com risco de piora clínica. Febre e dispneia de início recente durante o período de isolamento foram consideradas sintomas de alerta associados ao agravamento clínico e justificam avaliação médica imediata.

Background: The quarantine and social distancing implemented during COVID 19 pandemic may hamper the quality of life of the population. Aim: To determine the factors associated with a low quality of life during COVID 19 quarantine in Chilean adults. Material and Methods: The SF-36 survey about quality of life was answered by 1,082 Chilean adults aged between 18 and 60 years, who were quarantined by the COVID-19 health alert. Other variables studied were sociodemographic background, nutritional status, lifestyles, level of physical activity, sedentary behavior and sleep hours. Risk factors associated with low quality of life were identified by logistic regression analysis for each of the 8 dimensions evaluated in the SF-36 questionnaire. Results: The factors that increased the probability of having a lower general health perception were being female (Odds ratio (OR) = 1.29; p = 0.05), being physically inactive (OR = 2.76 p < 0.01), unhealthy hours of sleep (OR = 1.58, p < 0.01), smoking (OR = 1.59, p < 0.01) and eating junk food (OR = 2.26; p < 0.01). For the other dimensions of quality of life, the most frequently repeated factors were being female, junk food consumption, and being physically inactive and sedentary. Conclusions: There are factors associated with a low quality of life during the quarantine of the COVID-19 pandemic in the Chilean population. Their identification could reinforce remedial actions at the government level to benefit the health of the population during this health emergency.
