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.

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.

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.

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.

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.

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.

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).

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.

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.

Cancer is a chronic non-communicable disease associated with a high mortality burden. The prevalence of cancer is increasing rapidly worldwide. However, this scenario will be worse in low and middle-income countries such as Chile, where 70% of cancer deaths occur. The aim of this review was to assess the epidemiological scenario of cancer and its projection for the Chilean population. In Chile, 53,365 new cases of cancer were diagnosed in 2018, led by prostate, colorectal, breast, stomach, lung and gallbladder cancer. From 1986 to 2016, cancer increased by 109%. When we reviewed mortality by sex, stomach and prostate cancer were responsible for more than 30% of cancer deaths among men. However, for women the first three places were occupied by breast, colorectal and lung cancer, as in the rest of the world. Considering that 40% of cancers are related to unhealthy lifestyles, working on the prevention of modifiable risk factors represents an opportunity for the creation of public health policies that allow changes at the environmental and individual level.

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.

BACKGROUND: The assessment of frailty among older people could help to reduce its social and health burden. AIM: To determine and characterize the prevalence of frailty in Chilean older adults. MATERIAL AND METHODS: We studied 233 participants, aged > 60 years, participating in the Chilean National Health Survey 2016-2017. Frailty was assessed using modified Fried criteria. Thus, people classified as frail should meet at least 3 out of the 5 criteria (low strength, low physical activity, low body mass index, slow walking pace and tiredness). RESULTS: The prevalence of frailty was 10.9% (7.7% for men and 14.1% for women). The prevalence of pre-frailty was 59.0% whereas 30.1% of participants were classified as robust. At the age of 80 years 58 and 62% of men and women were frail, respectively. These figures increased to 90 and 87% at the age of 90 years. The prevalence of pre-frailty increased from 43 to 92.1% among men and from 76% and 78% among women from the ages of 60 to 90 years, respectively. CONCLUSIONS: The prevalence of frailty increased markedly with age. It is important to implement prevention strategies to allow an early identification of high-risk individuals.

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.

BACKGROUND: It is unknown if nutritional status could influence the accuracy of self-reported physical activity (PA) levels. AIM: To compare PA measured using the international physical activity questionnaire (IPAQ) and by accelerometry (ActiGraph) according to nutritional status in Chilean adults. MATERIAL AND METHODS: This is an observational cross-sectional study that used information from the GENADIO project carried out in Chile between 2009-2011. The sample consisted of 322 people. PA levels and sitting time were determined through the IPAQ self-report questionnaire and ActiGraph accelerometers (GTM1). The nutritional status was determined according to body mass index (BMI). RESULTS: Compared with the measurement made with accelerometry, the IPAQ self-report questionnaire underestimated the levels of light PA, total PA and sedentary time in -171.5, -54.8 and -40.6 min / day, respectively. However, IPAQ overestimated the levels of moderate PA and vigorous PA in 91.0 and 47.3 min/day respectively, compared with accelerometry. Compared with normal weight, obese subjects reported higher levels of moderate PA (105.5 and 48.9 min/day, respectively) and vigorous PA (54.1 and 38.3 min/day respectively). Total PA had a greater delta of underestimation between IPAQ and accelerometer measurements in normal weight than in obese subjects (-122.1 vs -16.5 min/day, respectively). CONCLUSIONS: The measurement of PA by means of a self-report questionnaire was discrepant with its objective measurement with an accelerometer. The discrepancy is even higher in obese people.

BACKGROUND: One of the side effects of cancer treatment is a low level of physical activity (PA) due to fatigue and pain. AIM: To quantify PA levels in Chilean people with cancer. MATERIAL AND METHODS: Analysis of the National Health Survey 2016-2017 including 6,233 participants, comparing those with and without a self-report of cancer was conducted. Levels of PA and sitting time were assessed using the Global Physical Activity Questionnaire. RESULTS: 3% of participants [confidence intervals (CI): 2.6; 3.9] reported having cancer and 34% [95% CI: 22.7; 46.7] of these reported being physically inactive, compared to 25% [95% CI: 22.5; 27,3] of those without cancer. Participants with cancer performed 56 and 77 minutes/day lower vigorous and total PA than participants without cancer. No differences between groups were observed for commuting PA, moderate PA and sedentary time. Lower level of PA was independent of the years elapsed since the diagnosis of cancer. CONCLUSIONS: People with cancer are less physically active than their counterparts without the disease.

OBJECTIVE: The aim of the study was to determine the main factors (sociodemographic, anthropometric, lifestyle and health status) associated with high Na excretion in a representative population of Chile. DESIGN: Na excretion (g/d), a valid marker of Na intake, was determined by urine analysis and Tanaka's formulas. Blood pressure was measured by trained staff and derived from the mean of three readings recorded after 15 min rest. The associations of Na excretion with blood pressure and the primary correlates of high Na excretion were determined using logistic regression. SETTING: Chileans aged ≥15 years.ParticipantsParticipants (n 2913) from the Chilean National Health Survey 2009-2010. RESULTS: Individuals aged 25 years or over, those who were obese and those who had hypertension, diabetes or metabolic syndrome were more likely to have higher Na excretion. The odds for hypertension increased by 10·2 % per 0·4 g/d increment in Na excretion (OR=1·10; 95 % CI 1·06, 1·14; P < 0·0001). These findings were independent of major confounding factors. CONCLUSIONS: Age, sex, adiposity, sitting behaviours and existing co-morbidities such as diabetes were associated with higher Na excretion levels in the Chilean population. These findings could help policy makers to implement public health strategies tailored towards individuals who are more likely to consume high levels of dietary salt.

The aim of this study was to investigate the association between physical activity (PA), both occupational (OPA) and during leisure time (LTPA), with obesity and cardiovascular risk factors in Chilean adults. 5,157 participants from the Chilean National Health Survey 2009-2010 were included in this study. OPA and LTPA levels were assessed using the Global Physical Activity Questionnaire. The association between both PA with obesity and cardiovascular risk factors was determined using logistic regression. Our findings showed a significant trend between higher LTPA and lower odds for obesity (OR 0.64 [95% CI: 0.53; 0.76], central obesity 0.52 [0.44; 0.61]) and other cardiovascular risk factors including diabetes (OR: 0.72 [0.55; 0.94]), hypertension (OR: 0.59 [0.50; 0.71]) and metabolic syndrome (OR: 0.62 [0.50; 0.78]). In contrast, OPA was only associated with lower odds of diabetes (OR: 0.79 [0.65; 0.98]) and hypertension (0.85 [0.74; 0.98]). In conclusion, LTPA was associated with a lower risk of all major cardiovascular risk factors, whereas OPA was only associated with a lower risk of diabetes and hypertension.

OBJECTIVE: .To use a new methodology to classify the level of physical activity (PA) by combining the levels of PA and sedentary time (SED) in order to establish its association with metabolic syndrome (MS). MATERIALS AND METHODS: A representative sample of Chilean adults (≥18 years old) who participated in the National Health Survey (ENS 2009-2010) was included in this study (n=5 040). Four categories were created using a combination of PA and SED levels through the GPAQ questionnaire. MS was defined accord- ing to the norms established by NCEP ATP-III. RESULTS: A lower probability of MS was observed only in the categories that comply with the international recommendations of PA, "active and low-SED" (OR=0.72 [0.57 to 0.91]) and "active and high-SED" (OR=0.63 [0.49 to 0.81]).While the level of SED (high/low) was not associated with a significant reduction of MS in any of the groups. CONCLUSIONS: This type of classification demonstrates that the main strategy to reduce the risk of MS should be associated with compliance with the recommendations of PA.
OBJETIVO: Asociar una nueva e integradora clasificación de actividad física (AF) y sedentarismo con riesgo de síndrome metabólico (SM) en una muestra representativa de adultos chilenos. MATERIAL Y MÉTODOS: Se incluyeron 5 040 parti- cipantes de la Encuesta Nacional de Salud de Chile 2009-2010. Fueron creadas cuatro categorías mediante una combinación entre niveles deAF y sedentarismo (SED) usando el cuestio- nario GPAQ. El SM fue definido según las normas del NCEP ATP-III. RESULTADOS: Se observa una menor probabilidad de presentar SM sólo en las categorías que cumplen con las recomendaciones internacionales de AF (p<0.05), "activo y bajo-SED" (RM=0.72 [0.57 a 0.91]) y "activo y alto-SED" (RM=0.63 [0.49 a 0.81]). El nivel de sedentarismo (alto/bajo) no se asoció con una reducción significativa de SM en ninguno de los grupos. CONCLUSIONES: Este tipo de clasificación demuestra que la principal estrategia para reducir elriesgo de SM debiera estar asociada con cumplir las recomendaciones de AF.

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.

Background Sleep duration may be a risk factor for cognitive impairment. Aim To investigate the association between sleep duration and cognitive function in Chilean older adults. Material and Methods We analyzed information from 1,384 participants aged > 60 years participating in the National Health Survey 2009-2010 who were assessed with the Mini Mental State Examination (MMSE) and self-reported their average daily sleep hours. Logistic regression analysis was performed to investigate the association between MMSE and sleep duration. Results Compared to those participants who reported sleeping 7 hours per day, those that reported sleeping < 5 hours had a higher odd for cognitive impairment (Odds ratio (OR): 3.66 [95% confidence intervals (CI: 1.69; 7.95], p < 0.01). Similarly, those who reported sleeping > 8 hours per day also showed a higher odd for cognitive impairment (OR: 2.56 [95% CI: 1.32; 4.95], p < 0.01). This association was even stronger for people who reported more than 10 hours of sleep per day (OR: 4.46 [95% CI: 1.32; 4.95], p < 0.01). Conclusions Long and short sleep duration is associated with cognitive impairment in older adults in Chile independent of major confounding factors.
