Autoconcepto físico, motivación de logro y actitudes hacia la Educación Física

El propósito de este estudio fue analizar la influencia del autoconcepto físico en relación con la motivación de logro y las actitudes de estudiantes de enseñanza media en la asignatura de Educación Física y Salud. Además, se buscó explorar las disparidades en las percepciones entre hombres y mujeres, así como entre aquellos que participan en actividades físico-deportivas. Para llevar a cabo la investigación, se empleó un enfoque cuantitativo con un alcance descriptivo-correlacional, utilizando un cuestionario aplicado a una muestra de 279 estudiantes de la región del Biobío, Chile. Este instrumento evaluó diversas dimensiones del autoconcepto físico, la motivación de logro y las actitudes hacia la asignatura. Los principales resultados indican que la actividad física constante se vincula con una mejor evaluación en estas dimensiones. Los hombres muestran una percepción corporal más positiva y mayor disposición para la participación activa, mientras que las mujeres experimentan niveles elevados de ansiedad y percepción de dificultad. La actividad física constante se asocia con percepciones más favorables en diversas dimensiones. Estos resultados resaltan la importancia de considerar género y nivel de actividad física al diseñar estrategias educativas en Educación Física y Salud en la enseñanza media.

The purpose of this study was to analyze the influence of physical self-concept in relation to achievement motivation and attitudes of high school students in the subject of Physical Education and Health. In addition, we sought to explore the disparities in perceptions between men and women, as well as between those who participate in physical-sports activities. To carry out the research, a quantitative approach with a descriptive-correlational scope was used, using a questionnaire applied to a sample of 279 students from the Biobío region, Chile. This instrument evaluated various dimensions of physical self-concept, achievement motivation, and attitudes toward the subject. The main results indicate that constant physical activity is linked to a better evaluation in these dimensions. Men show a more positive body perception and greater willingness to actively participate, while women experience high levels of anxiety and perceived difficulty. Constant physical activity is associated with more favorable perceptions in various dimensions. These results highlight the importance of considering gender and level of physical activity when designing educational strategies in Physical Education and Health in secondary education.

Asociación entre cáncer y fitness cardiorrespiratorio en población chilena: Resultados de la Encuesta Nacional de Salud 2016-2017

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.

Aproximación a la calidad percibida de un servicio deportivo universitario. Un estudio de caso

La población joven y adulta de Chile presenta altos niveles de inactividad física y sedentarismo, lo que coincide con los rangos etarios de los estudiantes universitarios. En este sentido, es escasa la evidencia científica que ha estudiado la calidad de los servicios deportivos que entregan las instituciones de educación superior, tanto a nivel latinoamericano, como chileno. Por lo tanto, este estudio tuvo como objetivo evaluar la calidad del servicio de la Unidad de Deportes y Recreación de la Universidad Católica de la Santísima Concepción de Chile, mediante la percepción que manifiestan los estudiantes que asisten a los talleres deportivos y de actividad física. Se aplicó el cuestionario SERVPERF que mide cinco dimensiones: elementos tangibles, fiabilidad, capacidad de respuesta, seguridad y empatía, según el grado de satisfacción de los usuarios. La investigación tuvo un enfoque cuantitativo y de tipo descriptivo. La muestra fue de 70 participantes (55 mujeres y 15 hombres). En general, los resultados mostraron una buena percepción y evaluación de todas las dimensiones del cuestionario. La dimensión seguridad fue la mejor valorada y la dimensión Elementos tangibles fue la que mostró una más baja evaluación.

A população jovem e adulta do Chile apresenta altos níveis de inatividade física e estilos de vida sedentários, o que coincide com as faixas etárias dos estudantes universitários. Nesse sentido, há poucas evidências científicas que tenham estudado a qualidade dos serviços esportivos prestados pelas instituições de ensino superior, tanto na América Latina quanto no Chile. Portanto, o objetivo deste estudo foi avaliar a qualidade do serviço prestado pela Unidade de Esportes e Recreação da Universidad Católica de la Santísima Concepción, no Chile, por meio da percepção dos alunos que participam das oficinas de esportes e atividades físicas. Foi aplicado o questionário SERVPERF, que mede cinco dimensões: elementos tangíveis, confiabilidade, capacidade de resposta, segurança e empatia, de acordo com o grau de satisfação do usuário. A pesquisa teve uma abordagem quantitativa e descritiva. A amostra foi composta por 70 participantes (55 mulheres e 15 homens). Em geral, os resultados mostraram uma boa percepção e avaliação de todas as dimensões do questionário. A dimensão Segurança foi a mais bem avaliada e a dimensão Elementos tangíveis apresentou a avaliação mais baixa.

The young and adult population of Chile presents high levels of physical inactivity and sedentary lifestyle, which coincides with the age ranges of university students. In this sense, there is little scientific evidence that has studied the quality of sports services provided by higher education institutions, both at the Latin American and Chilean levels. Therefore, this study aimed to evaluate the quality of the service of the Sports and Recreation Unit of the Universidad Católica de la Santísima Concepción de Chile, through the perception expressed by students who attend sports and physical activity workshops. The SERVPERF questionnaire was applied, which measures five dimensions: tangible elements, reliability, response capacity, security and empathy, according to the degree of user satisfaction. The research had a quantitative and descriptive approach. The sample consisted of 70 participants (55 women and 15 men). In general, the results showed a good perception and evaluation of all the dimensions of the questionnaire. The security dimension was the best valued and the tangible elements dimension was the one that showed the lowest evaluation.

Relación entre características antropométricas, autopercepción del índice de masa corporal, condición física y hábitos alimentarios en estudiantes universitarios de salud y educación

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.

Niveles de actividad física y tiempo sedente en personas mayores con fragilidad: resultados de la Encuesta Nacional de Salud 2016-2017 / Levels of physical activity and sitting time in elderly people with fragility: results of the 2016-2017 National Health Survey

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.

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.

[Cardiorespiratory fitness in Chilean cancer patients: A comparative Analysis]. / Asociación entre cáncer y fitness cardiorrespiratorio en población chilena: Resultados de la Encuesta Nacional de Salud 2016-2017.

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.

Anxiety, Low Self-Esteem and a Low Happiness Index Are Associated with Poor School Performance in Chilean Adolescents: A Cross-Sectional Analysis.

OBJECTIVE: To analyze the relationship between anxiety, self-esteem, happiness index and primary school students' academic performance in Chilean adolescents from the Biobío province. METHODOLOGY: 733 (46.1% girls; 12 (1.3 years)) public primary school students that completed the 2018 Health and School Performance Survey carried out in the Biobío province were included in this cross-sectional analysis. The BECK Anxiety Inventory (BAI) was used to measure anxiety while happiness index and self-esteem were measured using the subjective happiness scale and the Rosenberg self-esteem scale, respectively. School performance was measured by grade point average (GPA) of language, math, physical education and cumulative GPA, and behavior associated with cognition in the school context was also considered. The relationship between mental health indicators and school performance was investigated using a one-way ANOVA and Pearson correlation. RESULTS: In comparison to students with low anxiety levels and high self-esteem and happiness levels, students with higher anxiety levels, lower self-esteem and happiness levels perceived themselves as having memory problems. They were also slower to solve math problems, had a shorter attention span in class and presented more difficulties in solving complex tasks, as well as being more nervous during testing. These students also got the lowest grade point average in math, language and physical education. CONCLUSIONS: High anxiety levels, low self-esteem and low happiness levels were associated with lower school performance and weaker behavior associated with cognition in Chilean adolescents. Implementing plans of emotional education and mental health could improve academic achievement.

The Practice of Vigorous Physical Activity Is Related to a Higher Educational Level and Income in Older Women.

Few studies have shown evidence about the factors that can determine physical practice in women over 60 years of age due to educational, economic, social, or health inequalities. Its knowledge could help to understand the determinants that encourage the practice of physical activity and the improvement of health in women over 60. Therefore, the aim of this research was to evaluate the level of studies, income, and the usefulness of social and health services in physically active older women according to the level of activity they practice. The IPAQ (International Physical Activity Questionnaire) and CUBRECAVI (subjective health scale) scales have been applied to a sample of 257 women between 61 and 93 years old (M = 69.44, SD = 4.61). The results have shown that those with vigorous physical activity are related to higher levels of education (p < 0.001) and income (p = 0.004). Furthermore, being dissatisfied with social and health services is associated with low levels of physical activity (p = 0.005). Older women who perform physical activity regularly are associated with high levels in some of the socio-environmental aspects of quality of life. High physical activity is related to a higher educational level and income. Socio-environmental factors generate social inequalities and modulate the lifestyles of older women.

Niveles de actividad física y tiempo sedente según ingreso económico en Chile: resultados de la Encuesta Nacional de Salud 2016-2017 / Association between physical activity and income levels in chilean adults

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.

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.

Fitness cardiorrespiratorio estimado mediante ecuación y su caracterización sociodemográfica en población chilena: Resultados de la Encuesta Nacional de Salud 2016-2017

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.

[Association of physical inactivity with low levels of education]. / Nivel educativo y su asociación con niveles de actividad física en Chile.

BACKGROUND: A higher educational level is associated with healthier lifestyles. AIM: To assess the association between the level of compliance with physical activity recommendations and years of formal education in Chilean adults. MATERIAL AND METHODS: Analysis include 6,174 participants from the National Health Survey 2016-2017. Physical activity levels were assessed through the Global Physical Questionnaire (GPAQ v2). Physical inactivity was defined as < 600 MET/minute/week. RESULTS: Among subjects without education, 44% and 27% of women and men respectively, were physically inactive. Among women and men with the highest number of years of education (> 16) the figures for physical inactivity were 27% and 15% respectively. The odds for not meeting the physical activity recommendations was 2.3 [95% confidence intervals (CI): 1.57; 3.38] and 3.9 [95% CI: 2.27; 6.95] in women and men without any formal education respectively, as compared with those who reported 12 years of education. Women and men who reported a high level of education ≥ (16 years) did not show significant differences compared to the reference group. CONCLUSIONS: People with low levels of education are were likely to be physically inactive.

Auto reporte de la velocidad de marcha y su asociación con marcadores de adiposidad y riesgo cardiovascular en Chile / Association of self-reported walking speed with markers of adiposity and cardiovascular risk in Chile

Background Walking speed is a strong predictor of non-communicable diseases and mortality. Aim To investigate the association of self-reported walking pace with adiposity, metabolic and cardiovascular markers in the Chilean population. Material and Methods Analysis of data from 5,077 participants of the 2009-2010 National Health Survey (ENS 2009-2010). Walking speed was self-reported as average or slow pace. Body mass index (BMI), waist circumference (WC), blood pressure, blood glucose, glycosylated hemoglobin and lipid profile were the outcome. Results In Chile, 11% (95% confidence intervals [CI]: 10.0; 12.7) of the population reported a slow walking pace. Compared with average walking people, those reporting a slow pace had a higher body weight (difference (∆) 5.65 kg [95% CI: 3.22; 8.09], p < 0.01), BMI (D 2.48 kg/m 2 [95% CI: 1.53; 3.44], p < 0.01), WC (D 6.23 cm [95% CI: 4.12; 8.34], p < 0.01), serum triglycerides (D 30,9 mg/dl [95% CI: 5,31; 57,5], p = 0.018), and lower HDL cholesterol (D -2.32 mg/dl [95% CI: -4,24; -0,34], p = 0.022). Those reporting a slow pace had also a higher odd of being obese (odds ratio (OR): 2.46 [95% CI: 1.82; 3.33], p < 0.01), being diabetic (OR: 1.54 [95% CI: 1.02; 2.40], p = 0.018) and having metabolic syndrome (OR: 2.03 [95% CI: 1.30; 3.18], p = 0.002). Conclusions In Chilean adults, slow walking pace is associated with and unfavorable adiposity and lipid profile, including a higher probability of being obese, diabetic and having metabolic syndrome.

Nivel educativo y su asociación con niveles de actividad física en Chile / Association of physical inactivity with low levels of education

Background: A higher educational level is associated with healthier lifestyles. Aim: To assess the association between the level of compliance with physical activity recommendations and years of formal education in Chilean adults. Material and Methods: Analysis include 6,174 participants from the National Health Survey 2016-2017. Physical activity levels were assessed through the Global Physical Questionnaire (GPAQ v2). Physical inactivity was defined as < 600 MET/minute/week. Results: Among subjects without education, 44% and 27% of women and men respectively, were physically inactive. Among women and men with the highest number of years of education (> 16) the figures for physical inactivity were 27% and 15% respectively. The odds for not meeting the physical activity recommendations was 2.3 [95% confidence intervals (CI): 1.57; 3.38] and 3.9 [95% CI: 2.27; 6.95] in women and men without any formal education respectively, as compared with those who reported 12 years of education. Women and men who reported a high level of education ≥ (16 years) did not show significant differences compared to the reference group. Conclusions: People with low levels of education are were likely to be physically inactive.

[Sociodemographic Patterning of Cardiorespiratory Fitness Derived by Equation in the Chilean Population: Findings from the Chilean Health Survey 2016-2017]. / Fitness cardiorrespiratorio estimado mediante ecuación y su caracterización sociodemográfica en población chilena: Resultados de la Encuesta Nacional de Salud 2016-2017.

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.

[Factors associated with cognitive impairment in older adults in Chile]. / Factores asociados al deterioro cognitivo en personas mayores en Chile.

BACKGROUND: The risk factors for the development of cognitive impairment are not well known. AIM: To identify socio-demographic, lifestyle and health-related factors associated with cognitive impairment in older Chilean adults. MATERIAL AND METHODS: Data analysis of 1,384 participants ≥ 60 years who participated in the National Health Survey of Chile 2009-2010. Sociodemographic, lifestyle and health-related factors were used as exposure variables of interest. Cognitive impairment was assessed using an abbreviated version of the Mini Mental test and defined as a score < 13 points of a maximum of 19. A logistic regression was used to identify factors associated with cognitive impairment. RESULTS: In this sample, the prevalence of cognitive impairment was 11.6 [95% confidence intervals (CI): 8.8; 15.2]. The factors associated with cognitive impairment were age (Odds ratio (OR) for > 76 years: 4.89, p < 0.01), male sex (OR: 2.42, p = 0.02), lower education (OR: 21.6, p < 0.01), physical inactivity (OR: 2.07, p = 0.02), sedentary behavior (OR: 2.23, p = 0.01), sleeping > 9/hours/day (OR: 2.98, p = 0.01), consumption of < 5 portions/day of fruit and vegetables (OR: 2.02, p = 0.05), having an unhealthy lifestyle (OR: 6.10, p = 0.0001), being underweight (OR: 3.67, p < 0.01), obesity (OR: 3.32, p = 0.03), having hearing impairment (OR: 2.26, p = 0.02), having a visual impairment (OR: 3.89, p < 0.01), a history of depression (OR: 3.03, p = 0.01) and having a physical disability (OR: 5.63, p < 0.01). CONCLUSIONS: We identified 14 factors associated with cognitive impairment. Although some of these factors were non-modifiable such as age and sex, most of them could be modified by implementing prevention programs aiming to improve lifestyle behaviors in older adults in Chile.

[Factors associated with falls in older adults in chile. Analysis of the National Health Survey 2009-2010]. / Factores asociados a caídas en adultos mayores chilenos: evidencia de la Encuesta Nacional de Salud 2009-2010.

BACKGROUND: A decrease in functional capacity due to ageing is one of the main risk factors for falls in older people. AIM: To investigate factors associated with falls in Chilean older adults. MATERIAL AND METHODS: We analyzed the self-reports of falls of 1,334 people aged ≥ 60 years who answered the National Health Survey 2009-2010. Falls during the last 12 months were recorded. Lifestyle, socio-demographic and health status were analyzed. A Poisson regression with robust variance estimates was performed to identify factors associated with falls. RESULTS: Falls during the preceding year were reported by 37% of respondents (95% confidence intervals (CI): 32-42]. Fall frequency was higher in women (Prevalence ratio (PR):1.30 [95% CI:1.11; 1.53], p < 0.01) and those aged ≥ 75 years (PR:1.29 [95% CI:1.04; 1.61], p = 0.02). Hearing impairment (PR: 1.31 [95% CI: 1.07; 1.61], p < 0.01), impaired vision (PR:1.46 [95% CI:1.20; 1.77], p < 0.01), low self-reported wellbeing (PR: 1.41 [95% CI: 1.03; 1.94], p = 0.03) and disability (PR: 1.54 [95% CI:1.32; 1.79], p < 0.01) were associated with falls. However, multimorbidity (having ≥ 3 diseases) was negatively associated with falls (PR: 0.79 [95% CI: 0.63; 0.99], p = 0.04). CONCLUSIONS: Among older people, female sex, being aged > 75 years and having disability, hearing or vision impairment are risk factors for falls.
