RESUMEN

Positional cranial deformities are associated with prematurity evolving during the first 2 years of life due to the malleable characteristics of the skull, the first year being the main/primary therapeutic window for intervention. The objectives were (a) to describe health characteristics, peri- and postnatal pathologies, and positional cranial deformities in infants enrolled in an early intervention program and (b) to analyze the effects of a parent education-based intervention program on positional cranial deformity in premature infants. A quantitative, analytical, longitudinal study was conducted. It included 103 premature infants enrolled in an early intervention program (EIP) during the year 2017, all under 4 months of corrected age, to whom a parent education-based intervention program was applied. Cranial circumference, cranial width, diagonals, and anteroposterior diameter were measured, and the cranial asymmetry index (CAI) and cephalic index (CI) were calculated at baseline and during two subsequent evaluations separated by a 3-month period. The main results showed that 75.7% of the infants belonged to a very premature gestational age category, and 57.3% had an adequate weight for gestational age. The most frequent pathologies were premature jaundice, premature anemia, and hyaline membrane disease. The most frequent positional cranial deformity was plagiocephaly. The parent education-based intervention program resulted in (1) a significant decrease in the CAI and a significant increase in the IC, (2) plagiocephalies: an increase in the mild category and a decrease in the moderate + severe categories, (3) brachycephalies: a decrease in the absence category and an increase in the moderate + severe category, and (4) dolichocephalies: an increase in the absence category and a decrease in the mild category. In conclusion, the recommended first line of intervention was not enough for this population, and future studies should support the development of national clinical guidelines, where education is complemented with other therapeutic measures.

RESUMEN

INTRODUCTION: Physical inactivity is associated with a higher risk of chronic diseases. Regular stair use can contribute to increasing physical activity in the population. This study aimed to investigate the association between flights of stairs used daily at home and all-cause mortality and cause-specific incidence and mortality. METHODS: Of the 502,628 UK Biobank participants recruited between 2007 and 2010, 442,027 (mean age, 56±8 years) had available data and were included in the analyses conducted in 2023. Participants were categorized on the basis of flights of stairs climbed daily (1-5, 6-10, 11-15, >15). The disease-specific outcomes were cardiovascular disease, respiratory disease, cancer, type 2 diabetes, and all-cause dementia. Cox proportional hazard models, adjusted for sociodemographic, lifestyle, and health-related confounding factors, were used to analyze the associations between stair use frequency and health outcomes. RESULTS: Participants were followed up for a median of 10.9 years. Climbing stairs >15 times per day was associated with a lower risk of 8 of the 9 outcomes analyzed than not using stairs. The magnitude of association ranged from 3% (95% CI=0.94, 0.99) lower risk for all-cause cancer to 51% (95% CI=0.39, 0.60) lower risk of chronic obstructive pulmonary disease. Findings were similar for mortality outcomes, with the hazard ratios ranging from 0.82 (95% CI=0.77, 0.87) for all-cause cancer to 0.46 (95% CI=0.23, 0.92) for chronic obstructive pulmonary disease mortality. CONCLUSIONS: Stair use was associated with a lower risk of all-cause mortality and cause-specific incidence and mortality independent of confounding factors, including adiposity and multimorbidity.

RESUMEN

OBJECTIVE: To investigate the association between a lifestyle score and all-cause mortality in the Chilean population. DESIGN: Prospective study. SETTINGS: The score was based on seven modifiable behaviours: salt intake, fruit and vegetable intake, alcohol consumption, sleep duration, smoking, physical activity and sedentary behaviours. 1-point was assigned for each healthy recommendation. Points were summed to create an unweighted score from 0 (less healthy) to 7 (healthiest). According to their score, participants were then classified into: less healthy (0-2 points), moderately healthy (3-4 points) and the healthiest (5-7 points). Associations between the categories of lifestyle score and all-cause mortality were investigated using Cox proportional hazard models adjusted for confounders. Nonlinear associations were also investigated. PARTICIPANTS: 2706 participants from the Chilean National Health Survey 2009-2010. RESULTS: After a median follow-up of 10·9 years, 286 (10·6 %) participants died. In the maximally adjusted model, and compared with the healthiest participants, those less healthy had 2·55 (95 % CI 1·75, 3·71) times higher mortality risk due to any cause. Similar trends were identified for the moderately healthy group. Moreover, there was a significant trend towards increasing the mortality risk when increasing unhealthy behaviours (hazard ratio model 3: 1·61 (95 % CI 1·34, 1·94)). There was no evidence of nonlinearity between the lifestyle score and all-cause mortality. CONCLUSION: Individuals in the less healthy lifestyle category had higher mortality risk than the healthiest group. Therefore, public health strategies should be implemented to promote adherence to a healthy lifestyle across the Chilean population.

RESUMEN

To investigate how frailty modifies the association of sitting time with all-cause and cardiovascular mortality in Chilean adults. This prospective study included 2,604 participants aged ≥35 from the Chilean National Health Survey 2009-2010. Sitting time was self-reported, while frailty was assessed using a 36-item Frailty Index. Sitting time was categorized as low, medium, and high. Cox proportional hazard models were used to estimate the risk of mortality stratified for the sitting time categories. Over a median follow-up of 8.9 years, 311 participants died, 28% of them due to cardiovascular events. Frail people with prolonged sitting time were at higher risk of all-cause and cardiovascular mortality (hazard ratio 3.13; 95% confidence interval [2.06, 4.71] and hazard ratio 2.41; 95% confidence interval [1.50, 3.64], respectively). The observed risk was higher in women than men. Public health and individual strategies should be implemented to decrease sitting time across the population, with special attention on frail people.

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.

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

ANTECEDENTES: Tanto el gen FTO (Fat-mass and obesity-associated-gene) y el tiempo sedente se asocian a obesidad, sin embargo, se desconoce si el tiempo sedente puede modificar la predisposición genética a la obesidad. Por ende, el objetivo de este estudio fue investigar si la asociación entre el polimorfismo rs9939609 del gen FTO y marcadores de adiposidad podrían ser modificados por el tiempo sedente. MÉTODOS: Este estudio de corte transversal incluye a 409 participantes del estudio GENADIO. Los marcadores de adiposidad estudiados fueron peso corporal, índice de masa corporal (IMC), perímetro de cintura (PC) y porcentaje masa grasa. El tiempo sedente se determinó mediante acelerometría de movimiento. La interacción entre el gen FTO (rs9939609) y el tiempo sedente sobre los marcadores de adiposidad se determinó mediante análisis de regresión múltiple. RESULTADOS: Tanto la variante de riesgo del gen FTO como el tiempo sedente se asociaron a mayor peso corporal, IMC, PC y masa grasa. Sin embargo, la asociación entre tiempo sedente y marcadores de adiposidad fue mayor en personas portadoras del alelo de riesgo del gen FTO. Por cada 1 hora de incremento en tiempo sedente, el peso corporal incrementa en 1,36 kg ([95% IC: 0,27; 2,46], p = 0,015) y 2,95 kg ([95% IC: 1,24; 4,65], p = 0,001) en personas con la variante protectora (TT) versus aquellos con la variante de riesgo (AA), respectivamente. Resultados similares se encontraron para (PC). CONCLUSIÓN: La asociación entre la variante de riesgo de FTO y mayor nivel de adiposidad es más acentuada en individuos que presentan mayores niveles de sedentarismo.

BACKGROUND: The Fat-mass and obesity-associated-gene (FTO gene) and sedentary behavior time are associated with obesity. However, whether sedentary behavior time can modify the genetic predisposition to obesity in the Chilean population is unknown. Therefore, this study investigated the association between sedentary behavior, adiposity markers, and the FTO gene. METHODS: This cross-sectional study included 409 participants from the Genes, Environment, Diabetes, and Obesity (GENADIO) study. Adiposity markers studied included body weight, body mass index (BMI), waist circumference (WC), and fat mass. Sedentary behaviors were measured using accelerometers. Using multiple regression, we evaluated the interaction between sedentary behaviors and the FTO gene (rs9939609) on adiposity markers. RESULTS: Sedentary behaviors and the FTO genotype were positively associated with higher body weight, BMI, WC, and fat mass. However, the association between time of sedentary behavior and adiposity markers was higher in carriers of the risk variant for the FTO gene. For each hour of increment in sedentary behaviors, body weight increases by 1.36 kg ([95% CI: 0.27; 2.46], p = 0.015) and 2.95 kg ([95%CI: 1.24; 4.65], p = 0.001) in non-risk carriers (TT) versus risk carriers (AA), respectively. We observed similar results for WC, BMI, and body fat, but the interaction was significant only for WC. CONCLUSION: The association between sedentary behaviors and adiposity markers, especially body weight and WC, is higher in individuals who carry the risk variant of the FTO gene.

RESUMEN

INTRODUCCIÓN: El nuevo índice de obesidad basado en el volumen corporal (ABSI) ha sido asociado con enfermedades crónicas no transmisibles y mortalidad, independientemente de los valores del índice de masa corporal (IMC); sin embargo, se desconoce su asociación con diabetes mellitus tipo 2 (DMT2) en población chilena. OBJETIVO: determinar la asociación entre ABSI con glicemia, hemoglobina glicosilada (HbAc1) y DMT2 en población adulta chilena. MATERIALES Y MÉTODOS: Estudio transversal, incluyó a 4.874 participantes (edad media 43,3 años, 50,9% mujeres) de la Encuesta Nacional de Salud 2016-2017. ABSI fue calculado según la fórmula propuesta (basado en circunferencia de cintura, IMC y estatura. La Regresión de Poisson fue utilizada para investigar la asociación entre ABSI con DMT2 y regresión lineal para glicemia y HbAc1. Los análisis se ajustaron según factores sociodemográficos, de estilos de vida e IMC. RESULTADOS: ABSI fue positivamente asociado con glicemia (p < 0,001), HbA1c (p < 0,001) y DMT2 (p < 0,001). En el modelo más ajustado, por cada 0.025 unidad de aumento de ABSI, la glicemia aumentó en 1,78 mg/dL (95% IC: 1,21; 2,35) y la HbAc1en un 0,92% (95% IC: 0,49; 1,35). En cuanto a DMT2, la razón de prevalencia fue de 1,14 (95% IC: 1,09; 1,20), independiente de factores sociodemográficos, estilos de vida e IMC. CONCLUSIONES: ABSI se asoció de forma lineal con una mayor probabilidad de padecer DMT2, mayores niveles de glicemia y HbA1c en adultos chilenos. En este contexto, ABSI podría ser un índice complementario, independiente del IMC, para evaluar el riesgo de alteraciones metabólicas asociadas a obesidad.

INTRODUCTION: A Body Shape Index (ABSI) is a new obesity index based on body volume; this has been associated with chronic non-communicable diseases and mortality, independent of the values of the body mass index (BMI); however, its association with type 2 diabetes mellitus (T2DM) in the Chilean adult population is unknown. OBJECTIVE: To determine the association between ABSI, glycemia, glycosylated hemoglobin (HbAc1), and self-reported T2DM in the Chilean adult population. MATERIALS AND METHODS: In a cross-sectional study, 4,874 participants were included (mean age 43.3 years, 50.9% women) from the 2016-2017 National Health Survey. ABSI was calculated according to the proposed formula (based on waist circumference, BMI, and height). The Poisson regression was used to investigate the association between ABSI and T2DM, and linear regression was used to investigate the association between ABSI, glycemia, and HbAc1. Sociodemographic factors, lifestyle, and BMI adjusted the analyses. RESULTS: ABSI was positively associated with glycemia (p < 0.001), HbA1c (p < 0.001), and DMT2 (p < 0.001). In the most adjusted model, for every 0.025 unit increase in ABSI, glycemia increased by 1.78 mg/dL (95% CI: 1.21, 2.35) and HbAc1 by 0.92% (95% CI: 0.49, 1.35). Regarding T2DM, the prevalence ratio was 1.14 (95% CI: 1.09, 1.20), independent of sociodemographic factors, lifestyles, and BMI. CONCLUSIONS: ABSI was linearly associated with a higher probability of suffering from T2DM and higher levels of glycemia and HbA1c in Chilean adults. In this context, ABSI could be a complementary index, independent of BMI, to assess the risk of metabolic disorders associated with obesity.

RESUMEN

BACKGROUND: Physical fitness assessment of older adults is essential because it is a key component of functional independence and healthy aging. AIM: To establish physical fitness reference values for physically active older Chilean adults of both sexes and identify the variables associated with the deterioration of their physical condition. MATERIAL AND METHODS: Cross-sectional study that included 342 older adults aged 60 and over. Their physical fitness was assessed with the Senior Fitness Test (SFT). The timed up and go (TUG), chair stand (CS), arm curl (AC), and aerobic resistance (2 min) tests were evaluated. RESULTS: Performance in the physical fitness tests by age group decreased in all tests as older adults advanced in age. Scores for men were more evenly distributed across the different age groups. The main risk factors for the deterioration of physical fitness were age, sex, and body mass index (BMI) (p-value < 0.05). The primary risk factor for men was age and for women age and BMI. CONCLUSIONS: Performance of both men and women in the different SFT tests decreased as older adults aged. Age, sex, and BMI were the main risk factors for the deterioration of the physical fitness of physically active older adults.

RESUMEN

We aimed to investigate the association between frailty status and all-cause mortality in middle-aged and older people. We included 2661 individuals aged ≥ 35 from the Chilean National Health Survey 2009−2010. Mortality was determined through linkage with the Chilean Civil Registry and Identification. A 36-item frailty index (FI) was used to assess the frailty status. Associations between frailty status and all-cause mortality were assessed using Kaplan−Meier and Cox proportional hazard models adjusted for sociodemographic and lifestyle factors. A non-linear association was investigated using penalized cubic splines fitted in the Cox models. During an 8.9 median follow-up (interquartile range of 8.6−9.0), 308 individuals died (11.5%). Lower survival rates were observed in frail individuals compared to pre-frail and robust people (log-rank < 0.001). Compared with robust individuals, frail people had a higher mortality risk (HR: 2.35 [95% CI: 1.57 to 3.51]). Frail middle-aged individuals had a higher risk of dying independently of major risk factors.

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

Antecedentes: La velocidad de la marcha podría considerarse un marcador temprano de riesgo de deterioro cognitivo en personas mayores. Objetivo: Determinar la asociación entre velocidad de la marcha y sospecha de deterioro cognitivo en población mayor chilena. Métodos: Se incluyeron 1788 personas mayores de la Encuesta Nacional de Salud (ENS) 2016-2017 que tenían información sobre velocidad de marcha y sospecha de deterioro cognitivo. La velocidad de la marcha fue autorreportada y categorizada como marca lenta, normal y rápida. Sospecha de deterioro cognitivo fue evaluado a través del cuestionario Mini Mental abreviado. La asociación entre marcha y deterioro cognitivo fue investigada mediante análisis de regresión logística. Resultados: En comparación a las personas mayores que reportaron una velocidad de marcha rápida, aquellas que reportaron una marcha lenta presentaron 2,67 veces mayor probabilidad de tener deterioro cognitivo (OR: 2,67 [95% IC:1,62; 4,42], p<0,001). Al ajustar los modelos por variables de confusión sociodemográficas, estilos de vida y salud, la asociación disminuyó, pero, permaneció significativa (OR: 1,78 [95% IC:1,15; 3,17], p=0,047). Mientras que las personas mayores que reportaron tener una velocidad de marcha normal no presentaron asociación con deterioro cognitivo. Conclusión: Personas mayores que reportan una velocidad de marcha lenta presentaron una mayor probabilidad de sospecha de deterioro cognitivo. Considerando que el deterioro cognitivo es un síndrome geriátrico con alta prevalencia en población mayor, existe la necesidad de enfatizar en estrategias para un diagnóstico temprano, por lo cual la velocidad de marcha podría ser un instrumento útil.

Background: Walking pace could be considered an early risk marker of cognitive impairment in older people. Objective: To determine the association between walking pace and cognitive impairment in older Chilean adults. Methods: 1,788 adults older than 60 years from the 2016-2017 Chilean National Health Survey with data available in the exposure and outcome were included in this cross-sectional study. Walking pace was self-reported and categorised as slow, average and brisk. Cognitive impairment was assessed using the Abbreviated Mini-Mental questionnaire. Logistic regression analyses were performed to investigate the association between walking pace and cognitive impairment, logistic regression analyses - adjusted for sociodemographic, lifestyle and health-related covariates. Results: In the minimally adjusted model and compared to older adults who self-reported a brisk walking pace, those in the slow walking pace category were 2.67 times more likely to have cognitive impairment (OR: 2.67 [95% CI: 1.62, 4.42]). When the analyses were adjusted, the association was attenuated but remained significant (OR: 1.78 [95% CI: 1.15 3.17]). No associations were found between average pace walkers and cognitive impairment. Conclusion: Older adults who self-reported a slow walking pace having a higher likelihood of cognitive impairment than their counterparts who had a brisk walking pace. Considering that cognitive impairment is a geriatric syndrome with a high prevalence in the elderly, there is a need to emphasise strategies for an early diagnosis. Therefore, walking pace may be a useful marker to identify individuals at high risk of cognitive impairment.

RESUMEN

There has not been much study of risk profiles in older people according to different levels of practice in physical activity. For this reason, the aim of this research was to evaluate whether the elements that influence the quality of life and factors such as gender and education can predict the level of physical activity in the physically active elderly population. The Fernández−Ballesteros quality of life questionnaire and the WHO International Physical Activity Questionnaire were applied to a sample of 397 people with a mean age of 69.65 years (SD = 4.71). The results revealed the following predictive factors of practicing a low level of physical activity (p < 0.05): being a woman; having a low educational level; and low scores in activity and leisure and in functional skills. In conclusion, gender, education, functional skills, activity and leisure, and health are elements of quality of life that predict the level of physical activity performed by the elderly, where it is necessary to use leisure activities (visiting friends, playing games, running errands) as an indirect way to increase participation in physical activity.

RESUMEN

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.

RESUMEN

BACKGROUND: Telehealth is a novel therapeutic alternative. AIM: To determine the effects of a remote therapeutic physical exercise program (TPEP), based on telehealth, on functional physical capacity in people with knee or hip osteoarthritis. PATIENTS AND METHODS: An eight-week TPEP was undertaken by 36 participants with a mean age of 68 years. The control group received printed exercise instructions, while the experimental group received the same instructions plus TPEP using tutorial videos and voice messaging via WhatsApp. Both groups were evaluated at baseline and the end of the intervention with the Lower Extremity Functional Scale (LEFS), Barthel index (BI), Short Physical Performance Battery (SPPB), senior fitness test and with the Visual Analog Scale for pain (VAS). RESULTS: The experimental group decreased the VAS score and improved tandem balance, three-meter walk, sit and stand 5 times, sit and stand in 30 seconds, push-ups in 30 seconds, two minutes' walk, join the right hand behind the back and SPPB general score. The control group increased the BI score and improved the three meters walking test, sitting, and standing 5 times, sit and stand 30 seconds chair test, 2 minutes walking test and the SPPB general score. No differences between groups were observed for the LEFS scale, BI, VAS and functional capacity. CONCLUSIONS: A TPEP based on telehealth has similar effectiveness than a TPEP based on traditional paper-based intervention to improve functional physical capacity in patients with OA. (Rev Med Chile 2022; 150: 33-45).

Aim: To determine the effects of a remote therapeutic physical exercise program (TPEP), based on telehealth, on functional physical capacity in people with knee or hip osteoarthritis. PATIENTS AND METHODS: An eight-week TPEP was undertaken by 36 participants with a mean age of 68 years. The control group received printed exercise instructions, while the experimental group received the same instructions plus TPEP using tutorial videos and voice messaging via WhatsApp. Both groups were evaluated at baseline and the end of the intervention with the Lower Extremity Functional Scale (LEFS), Barthel index (BI), Short Physical Performance Battery (SPPB), senior fitness test and with the Visual Analog Scale for pain (VAS). RESULTS: The experimental group decreased the VAS score and improved tandem balance, three-meter walk, sit and stand 5 times, sit and stand in 30 seconds, push-ups in 30 seconds, two minutes' walk, join the right hand behind the back and SPPB general score. The control group increased the BI score and improved the three meters walking test, sitting, and standing 5 times, sit and stand 30 seconds chair test, 2 minutes walking test and the SPPB general score. No differences between groups were observed for the LEFS scale, BI, VAS and functional capacity. CONCLUSIONS: A TPEP based on telehealth has similar effectiveness than a TPEP based on traditional paper-based intervention to improve functional physical capacity in patients with OA.

RESUMEN

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.

RESUMEN

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.
