Associations of diabesity with all-cause and cardiovascular disease mortality: Findings from the Mexico City Prospective Study.

AIM: To investigate the joint associations of diabetes and obesity with all-cause and cardiovascular disease (CVD) mortality in the Mexico City Prospective Study. MATERIALS AND METHODS: In total, 154 128 participants (67.2% women) were included in this prospective analysis. Diabetes was self-reported, while body mass index was used to calculate obesity. Using diabetes and obesity classifications, six groups were created: (a) normal (no diabetes and normal weight); (b) normal weight and diabetes; (c) overweight but not diabetes (overweight); (d) overweight and diabetes (prediabesity); (e) obesity but not diabetes (obesity); and (f) obesity and diabetes (diabesity). Associations between these categories and outcomes were investigated using Cox proportional hazard models adjusted for confounder factors. RESULTS: During 18.3 years of follow-up, 27 197 (17.6%) participants died (28.5% because of CV causes). In the maximally adjusted model, participants those with the highest risk {hazard ratio (HR): 2.37 [95% confidence interval (CI): 2.24-2.51]}, followed by those with diabesity [HR: 2.04 (95% CI: 1.94-2.15)]. Similar trends of associations were observed for CVD mortality. The highest CV mortality risk was observed in individuals with diabesity [HR: 1.80 (95% CI: 1.63-1.99)], followed by normal weight and diabetic individuals [HR: 1.78 (95% CI: 1.60-1.98)]. CONCLUSION: This large prospective study identified that diabetes was the main driver of all-cause and CVD mortality in all the categories studied, with diabesity being the riskiest. Given the high prevalence of both conditions in Mexico, our results reinforce the importance of initiating prevention strategies from an early age.

Association between a lifestyle score and all-cause mortality: a prospective analysis of the Chilean National Health Survey 2009-2010.

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.

A scoping review of food and nutrition literacy programs.

The impact of food literacy (FL) and nutrition literacy (NL) programs on lifestyles and health is recognized in the literature, yet few studies systematize it. This study aims to deepen the understanding of FL/NL from the characterization of programs in terms of (i) theoretical foundations, conceptualization and measuring instruments; (ii) characterization of the FL/NL programs and results and (iii) limitations and future directions declared. A scoping review of original articles addressing FL/NL programs from the Web of Science, Scopus and PubMed databases published between 2015 and 2023. There was a somewhat restricted view of the construct and the absence of a clear boundary between FL and NL. Half of the studies reported theoretical foundations. The most used model was Social Cognitive Learning Theory. More significant development of programs was observed in Australia, using quasi-experimental designs. Most of the studies informed positive results. Limitations of the studies related to the sampling process, absence of a control group and lack of follow-up. It is suggested that long-term interventions consider economic, social and cultural factors. Despite that theoretical and empirical aspects should be revised, FL/NL programs are a suitable strategy to mitigate the social and health effects of inadequate nutrition.

Multimorbidity and 11-year mortality in adults: a prospective analysis using the Chilean National Health Survey.

Research on morbidity and mortality often emphasizes individual diseases over the cumulative effects of multimorbidity, especially in low- and middle-income countries. This study aimed to analyze the association between multimorbidity and all-cause mortality in a representative sample of the Chilean population. This longitudinal study used data from 3701 subjects aged ≥15 years who participated in the Chilean National Health Survey conducted between 2009 and 2010. We included 16 self-reported highly prevalent morbidities. All-cause mortality data from an 11-year follow-up were collected from the Chilean Civil Registry. The Cox proportional hazard model, adjusted for confounders, determined the association between multimorbidity categories and all-cause mortality. Of the total sample, 24.3% reported no morbidity, while 50.4% two or more. After adjustment, participants with four or more morbidities had a 1.66 times higher mortality risk [95% confidence interval (CI): 1.03-2.67] than those without morbidities. The mortality risk increased by 10% for each additional morbidity [HR: 1.09 (CI: 1.04-1.16)]. Multimorbidity was common in the Chilean population and increased the mortality risk, which greatly challenges the health system to provide an integral and coordinated approach to healthcare.

Association of Sitting Time With All-Cause and Cardiovascular Mortality: How Does Frailty Modify This Association?

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.

[Association between low vitamin D levels and cognitive impairment in Chilean older adults: findings of the National Health Survey 2016-2017]. / Asociación entre bajos niveles de vitamina D y deterioro cognitivo en personas mayores chilenas: Resultados de la Encuesta Nacional de Salud 2016-2017.

INTRODUCTION: Recent studies have shown that low vitamin D levels constitute a potential risk factor for the development of cognitive impairment. The present study aimed to investigate the association between vitamin D levels and the suspicion of cognitive impairment in Chilean older adults. MATERIAL AND METHOD: We performed a cross-sectional study, including 1,287 participants ≥ 65 years (56.8% were women, age range 65 to 97 years) from the Chilean National Health Survey. Cognitive impairment was assessed using the Mini Mental State Examination (MMSE). Participants were classified into three groups according to their vitamin D levels (> 29 ng/ml sufficient, 12-29 ng/ml deficit, and < 12 ng/ml severe deficit). The association between vitamin D levels and cognitive impairment was explored using logistic regression analysis, adjusted for confounding factors. RESULTS: The prevalence of vitamin D deficit and vitamin D severe deficit was 37.7% and 21.0%, respectively. Compared to older adults with sufficient levels of vitamin D, those with severe deficits had a 94% (OR: 1.94 [95% IC: 1.27; 1.66], p = 0.002) higher odds of cognitive impairment (unadjusted model). Adjusting according to sociodemographic factors, lifestyle, adiposity, sunlight exposure, and multimorbidity slightly attenuated the association to 61% (OR: 1.61 [95%IC: 1.03; 2.19], p = 0.046), but remain significant. CONCLUSION: A severe deficit of vitamin D was associated with higher odds of cognitive impairment in Chilean older adults independent of major confounding factors. Future studies are needed to provide causal evidence between vitamin D and the suspicion of cognitive impairment.

[ABSI obesity index and its association with type 2 diabetes mellitus in Chilean adults: a cross-sectional study of the ENS 2016-2017]. / Índice de obesidad ABSI y su asociación con diabetes mellitus tipo 2 en adultos chilenos: un estudio transversal de la ENS 2016-2017.

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.

[Association between educational level and suspicion of cognitive imparirment in Chilean older people]. / Asociación entre nivel educacional y sospecha de deterioro cognitivo en personas mayores chilenas: resultados de la Encuesta Nacional de Salud 2016-2017.

BACKGROUND: A low education level has been associated with cognitive impairment in older adults. AIM: To determine the association between educational attainment and suspicion of cognitive imparirment in older Chilean population. MATERIAL AND METHODS: Data from 2,005 adults aged ≥ 60 years assessed during 2016-2017 Chilean National Health Survey were included. Education was self-reported and categorized as primary: ≤ 8 years; secondary: 9 to 12 years and beyond secondary: > 12 years. suspicion of cognitive imparirment was assessed with the Mini-Mental questionnaire. RESULTS: Men and women with low education attainment had a higher prevalence of cognitive impairment (33% [95% confidence intervals (CI): 24; 41] and 27% [95% CI: 21; 33], respectively). Men who reported less schooling (≤ 8 years) were more likely to be at risk of suspicion of cognitive imparirment (Odds ratio (OR): 4.53 [95% CI: 1.10, 18.62]) compared to their peers. Women showed a substantially higher magnitude of association than men. The probability of suspicion of cognitive imparirment increased 9-times (OR: 9.96 [95% CI: 1.24; 79.6]) for 9-12 years and 18-times for ≤ 8 years of education (OR: 18.8 [95% CI: 2.42; 146.1]) compared to women with higher education. CONCLUSIONS: Older adults with low education attainment had an increased likelihood of developing suspicion of cognitive imparirment. However, the risk differs by sex, being higher in women than men.

A healthy eating score is inversely associated with depression in older adults: results from the Chilean National Health Survey 2016-2017.

OBJECTIVE: To investigate the relationship of a healthy eating score with depression in Chilean older adults. DESIGN: Cross-sectional study. SETTING: Older adults from the Chilean National Health Survey 2016-2017. Associations were analysed using complex samples multivariable logistic regressions adjusted for age, sex, socio-demographic, lifestyles (physical activity, smoking, alcohol consumption and sleep duration), BMI and clinical conditions (hypertension, diabetes, hypercholesterolaemia and cardiovascular diseases). PARTICIPANTS: The number of participants was 2031 (≥ 60 years). The Composite International Diagnostic Interview-Short Form was applied to establish the diagnosis of major depressive episode. Six healthy eating habits were considered to produce the healthy eating score (range: 0-12): consumption of seafood, whole grain, dairy, fruits, vegetables and legumes. Participants were categorised according to their final scores as healthy (≥ 9), average (5-8) and unhealthy (≤ 4). RESULTS: Participants with a healthy score had a higher educational level, physical activity and regular sleep hours than participants with an average and unhealthiest healthy eating score. Participants classified in the healthiest healthy eating score had an inverse association with depression (OR: 0·28, (95 % CI 0·10, 0·74)). Food items that contributed the most to this association were legumes (15·2 %) and seafood (12·7 %). CONCLUSION: Older adults classified in the healthiest healthy eating score, characterised by a high consumption of legumes and seafood, showed a lower risk for depression in a representative sample of Chilean population.

[Water intake in the Chilean population: Findings from the 2016-17 National Health Survey]. / Caracterización del consumo de agua en población chilena: resultados de la Encuesta Nacional de Salud 2016-2017.

BACKGROUND: Water is an essential nutrient for cellular homeostasis and life. Drinking ≥ 6 glasses (1.5 L/day) is the recommendation of daily water intake (RIAD). AIM: To characterize water intake, according to sociodemographic, anthropometric and lifestyles variables, in the Chilean adult population. MATERIAL AND METHODS: Analysis of data from 5,520 participants of the 2016-17 National Health Survey. Compliance with RIAD by population groups according to sociodemographic, anthropometric and lifestyle characteristics was studied through logistic regression analyses. RESULTS: Only 27.8% of the national population met the RIAD. Women, people over than 56 years of age, housewives, retired people, widowers, and non-smokers were less likely to meet the RIAD. The likelihood of not complying with RIAD in these segments of the population ranged from 28% to 62%. Conversely, participants who presented a higher likelihood of meeting RIAD were those who co-habiting, had a medium and higher educational level, followed a diet plan, and those who reported a good health and well-being. The likelihood of meeting with the RIAD for these population groups ranged from 47% to 116%. CONCLUSIONS: The likelihood of meeting the RIAD varied according to different sociodemographic, anthropometric, and lifestyle variables. Therefore, public policies for promoting water consumption should be focused on all age groups, but especially in those groups with the highest risk of underconsumption.

[Factors associated with depression in Chilean adults. Results of the 2016-2017 National Health Survey]. / Factores asociados a depresión en población chilena. Resultados Encuesta Nacional de Salud 2016-2017.

BACKGROUND: Depression is a highly prevalent disease in Chilean adults. AIM: To identify sociodemographic, biomedical, and psychosocial factors related with depression in a representative sample of the Chilean adult population. MATERIAL AND METHODS: Analysis of data from the National Health Survey 2016-2017 which included 5,291 participants aged > 15 years. Depression was assessed using the Composite International Diagnostic Interview (CIDI-SF). Association between sociodemographic data, health and psychosocial variables and depression was analyzed using Poisson regression with robust error. RESULTS: The probability of depression was higher in women than in men (prevalence ratio (PR) = 2.13 [95% confidence intervals (CI): 1.65, 2.75]). In both genders, the probability was higher in people with frailty (women: PR = 10.0 [95% CI: 1.86, 18.1] and men: PR = 3.38 [95% CI: 2.72; 4.20]), severe chronic pain (women: PR = 2.84 [95% CI: 1.93, 4.18 and men: PR = 6.41 [95% CI: 3.59, 9.40]), presence of two or more diseases (women: PR = 4.15 [95% CI: 2.78, 6.20 and men: PR = 2.60 [95% CI: 1.39, 3.81]), perception of permanent stress (women: PR = 11.0 [95% CI: 6.13, 16.0], men: PR = 21.0 [95% CI: 10.2, 31.7]), financial stress (women: PR = 2.57 [95% CI: 1.87, 3.27] men: PR = 4.27 [95% CI: 2.48, 6.06] and poor or very poor perception of health (women: PR = 5.02 [95% CI: 1.92, 8.12], men: 2.09 [95% CI: 0.49, 3.69]). In men, the probability of depression was higher for widowers than married man (PR = 5.58 [95% CI: 2.5, 8.25]), presence of goiter (PR = 4.03 [95% CI: 1.99, 6.07]) and low social support (PR = 1.95 [95% CI: 1.18; 2.72]). CONCLUSIONS: The factors associated with a higher probability of depression are diverse in nature. Among these being women, frailty, chronic pain, multimorbidity and high perception of stress are important factors.

[Legume consumption in chileans: findings from the 2016-2017 national health survey]. / Caracterización del consumo de legumbres en población chilena: resultados de la Encuesta Nacional de Salud 2016-2017.

BACKGROUND: Legumes are low cost and high-quality nutritional foods. In Chile, a twice per week legume consumption is recommended to promote health and prevent disease. AIM: To characterize the consumption of legumes according to sociodemographic and anthropometric variables in the Chilean adult population. MATERIAL AND METHOD: Analysis of data from 5,473 participants of the 2016-2017 National Health Survey. The compliance with legume consumption was studied in population groups, according to sociodemographic and anthropometric characteristics, through logistic regression analyses. RESULTS: Only 24% of all participants (51.4% of women) fulfilled legume intake recommendations. After adjusting for sociodemographic variables, the participants who were less likely to comply with the recommendation were widowers (Odds Ratio (OR): 0.58 [95% confidence intervals (CI): (0.40; 0.85]). On the contrary, people between 70-80 years (OR: 1.78 [95% CI: 1.11; 2.88]), those who resided in rural areas (OR: 1.62 [95% CI: 1.25; 2.10]) and those who resided in the Maule region (OR: 2.11 [95% CI: 1.37, 3.25]) had a higher likelihood of compliance. CONCLUSIONS: One out of four Chileans complied with the recommendations of legume consumption. Even though the results differed when stratified by sex, it is highlighted that living in rural areas increased the probabilities of an adequate legume consumption.

[Older people in Chile: the new social, economic and health challenge for the 21st century]. / Personas mayores en Chile: el nuevo desafío social, económico y sanitario del Siglo XXI.

Ageing will be one of the most significant social transformations of the 21st century worldwide. In the last 40 years, Chile has tripled its older adult population. As a result, by 2050 the country will have the highest proportion of older adults in Latin America. This remarkable growth reinforces the need to identify their current situation and to revise what is the society doing to maintain older people as active members. In this context, this narrative revision aimed to describe the sociodemographic, epidemiologic and sociocultural profile of the older Chilean adults. Besides, programs and public policies focused on the improvement of their quality of life were identified.

[Association of menopause with cardiovascular risk. Analysis of data from the 2016-17 Chilean national health survey]. / Menopausia y factores de riesgo cardiovascular en mujeres chilenas.

BACKGROUND: Menopause exposes women to an increased cardiovascular risk. AIM: To determine the association between menopause and cardiovascular risk factors in Chilean adult women using data from the National Health Survey (NHS) 2016-2017. MATERIAL AND METHODS: Data from 2,139 women over 40 years of age participating in the NHS 2016-2017, with information about menopause and cardiovascular risk factors was used. Expansion factors were applied to this sample, obtaining an expanded sample of 3,733,191 participants. Laboratory values (blood glucose, triglycerides, HDL and total cholesterol) and anthropometric measurements (body weight, height and waist circumference) were analyzed. The presence of hypertension, diabetes, and metabolic syndrome (MetS) were also recorded. RESULTS: Sixty seven percent of surveyed women were menopausal and had higher systolic blood pressure than non-menopausal participants. Menopause was significantly associated with hypertension (Odds ratio (OR): 2.43 [95% confidence intervals (CI): 1.71; 3.45], p < 0.01) and diabetes (OR: 2.05 [95% CI: 1.32; 3.19], p < 0.01). However, no association was observed with obesity, abdominal obesity or MetS. CONCLUSIONS: In these women, a positive association was identified between menopause and hypertension as well as diabetes.

[Prevalence of frailty among Chilean older people]. / Prevalencia de fragilidad en personas mayores de Chile: resultados de la Encuesta Nacional de Salud 2016-2017.

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.

[Association between cognitive impairment and depression in Chilean older adults]. / Diagnóstico médico de depresión se asocia a sospecha de deterioro cognitivo en adultos mayores.

BACKGROUND: Depression has been previously associated with cognitive impairment in high income country populations. However, its association in the Chilean population has not been investigated. AIM: To investigate the association between depression and cognitive impairment. MATERIAL AND METHODS: Data from 1384 Chilean adults aged > 60 years, participating in the National Health Survey 2009-2010 was analyzed. Cognitive impairment was assessed using the Mini Mental Examination score. The medical diagnosis of depression was self-reported. The association between depression and cognitive impairment was assessed using a logistic regression. RESULTS: Depression was positively associated with cognitive impairment. However, the magnitude of the association was higher in men (Odds ratio (OR) = 4.02 [95% confidence intervals (CI): 1.44; 6.61], p < 0.01]) than in women (OR = 2.23 [95%CI: 1.03; 3.43], p = 0.04). Older adults who were diagnosed for the first time with depression after 65 years of age, showed a stronger association with cognitive impairment (OR = 6.65 [95% CI: 2.39; 10.9], p < 0.01) than those diagnosed before 55 years. CONCLUSIONS: Our study confirms the association between depression and cognitive impairment. Further research is needed to elucidate the nature and potential mechanisms that link depression with cognitive impairment.

[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.

[Association between sleep duration and cognitive impairment in older people]. / ¿Cuál es la asociación entre el tiempo destinado a dormir y el desarrollo de deterioro cognitivo en adultos mayores chilenos?

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.

[Physical activity and sedentary behaviours are associated with cognitive impairment in Chilean older adults]. / Actividad física y tiempo sedente se asocian a sospecha de deterioro cognitivo en población adulta mayor chilena.

BACKGROUND: Lifestyle factors could promote healthy ageing. AIM: To investigate the association between physical activity (PA), sedentary behavior and cognitive impairment in Chilean older adults. MATERIAL AND METHODS: We included 1,390 participants from the National Health Survey (2009-2010). The Mini-Mental State Examination was used to diagnose cognitive impairment. Physical activity and sedentary behavior were assessed with the Global Physical Activity Questionnaire (GPAQ). Logistic regression was performed to investigate the associations. RESULTS: Compared with older adults with lower levels of PA (< 48 min/day), those with middle (48-248 min/day) and higher (>248 min/day) levels of PA had lower odds for cognitive impairment (Odds ratio (OR): 0.57 [95% confidence intervals (CI): 0.33; 0.82], p < 0.01 and 0.58 [95% CI: 0.32; 0.83], p < 0.01, respectively). Participants who reported spending more than 8 hours/day sitting had a high odds for cognitive impairment compared to those who spent < 4 hours/day (OR: 3.70 [95% CI: 1.37; 6.03], p = 0.01). CONCLUSIONS: Both PA and sedentary behavior were independently associated with cognitive decline independent of major confounding factors in Chilean older adults.
