Multimorbidity patterns can lead to differential risks for all-cause mortality. Within the Chilean context, research on morbidity and mortality predominantly emphasizes individual diseases or combinations thereof, rather than specific disease clusters. This study aimed to identify multimorbidity patterns, along with their associations with mortality, within a representative sample of the Chilean population. 3,701 participants aged ≥18 from the Chilean National Health Survey 2009-2010 were included in this prospective study. Multimorbidity patterns were identified from 16 chronic conditions and then classified using latent class analyses. All-cause mortality data were extracted from the Chilean Civil Registry. The association of classes with all-cause mortality was carried out using Cox proportional regression models, adjusting by sociodemographic and lifestyle variables. Three classes were identified: a) Class 1, the healthiest (72.1%); b) Class 2, the depression/cardiovascular disease/cancer class (17.5%); and c) Class 3, hypertension/chronic kidney disease class (10.4%). Classes 2 and 3 showed higher mortality risk than the healthiest class. After adjusting, Class 2 showed 45% higher mortality risk, and Class 3 98% higher mortality risk, compared with the healthiest class. Hypertension appeared to be a critical underlying factor of all-cause morbidity. Particular combinations of chronic diseases have a higher excess risk of mortality than others., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Nazar et al.

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.

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., (© The Author(s) 2023.

The World Health Organization has defined collective violence as the instrumental use of violence by people who identify themselves as members of a group against other individuals and have political, economic, or social objectives. In Chile, the "Social Outbreak" was used to describe an episode of collective violence, which began on October 18, 2019, triggered by a multitude of socioeconomic and political factors, with protests and mobilizations in the country's large and small cities; in central, commercial, and residential areas, that lasted for several months, affecting a large part of the population. The objective of the present study was to associate the social outbreak in Chile with its biological, psychological, and social effects on people's health and quality of life, as well as its characteristics in terms of exposure, proximity, type, and frequency. This was a cross-sectional study with non-probabilistic national-level sampling, conducted from 28 November 2019, to 3 March 2020. The instrument had four sections. A total of 2651 participants answered the survey; 70.8% were female, and the mean age was 35.2. The main disturbances perceived were protests (70.9%), alarm sounds (68.1%), shooting sounds (59.0%), and tear gas bombs (56.9%). When quantifying the magnitude of these associations, people who had a medium exposure have a higher probability (OR: 1.99, CI: 1.58; 2.50) of suffering three or more biological effects than people that have a low exposure, while people with higher exposition have a 4.09 times higher probability (CI: 3.11; 5.38). A similar pattern was observed regarding psychological effects, although social effects were primarily experienced by those with high exposure. Social networks, TV, and radio were the most used media among people who perceived a greater effect. People who lived, worked, or shopped near the disturbance's areas show a higher proportion negative effect.

Frailty is an increasingly frequent geriatric syndrome in the population; however, its regional prevalence in Chile has not been quantified., Aim: To determine the prevalence of frailty according to Chile's regions, using the Frailty Index (IF)., Material and Methods: In this cross-sectional study, data from 3,036 participants with 40 or more years of the National Health Survey 2016-17 were used. For the measurement of frailty, we created a 49-item IF, and everyone was given a score from 0 to 1. Based on the score obtained, we categorized the participants as: «robust», «pre-frail», and «frail». The prevalence was calculated and divided according to geographical areas (North, Center, and South), considering the 15 regions of Chile in force as of 2016., Results: At the national level, the prevalence of robust, pre-frail, and frail individuals was 47,6%, 40,6%, and 11,8%, respectively. 15,9% were women and 7,4% men; 18,9% of the sample had less than eight years of education. The Libertador General Bernardo OHiggins Region showed a higher prevalence of frailty (18,3%), followed by the Maule Region (16,7%), which also had a higher prevalence of pre-frailty (49,6%). The Tarapacá Region presented a higher prevalence of robust people (64,6%)., Conclusions: The prevalence off rail individuals was higher in the central zone of Chile, it increased as age increased, and it was higher in women with a lower educational level.

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.

Background: Triatomines are blood-sucking insects capable of transmitting Trypanosoma cruzi, the parasite that causes Chagas disease in humans. Vectorial transmission entails an infected triatomine feeding on a vertebrate host, release of triatomine infective dejections, and host infection by the entry of parasites through mucous membranes, skin abrasions, or the biting site; therefore, transmission to humans is related to the triatomine-human contact. In this cross-sectional study, we evaluated whether humans were detected in the diet of three sylvatic triatomine species (Mepraia parapatrica, Mepraia spinolai, and Triatoma infestans) present in the semiarid-Mediterranean ecosystem of Chile., Methods: We used triatomines collected from 32 sites across 1100 km, with an overall T. cruzi infection frequency of 47.1% (N = 4287 total specimens) by conventional PCR or qPCR. First, we amplified the vertebrate cytochrome b gene (cytb) from all DNA samples obtained from triatomine intestinal contents. Then, we sequenced cytb-positive PCR products in pools of 10-20 triatomines each, grouped by site. The filtered sequences were grouped into amplicon sequence variants (ASVs) with a minimum abundance of 100 reads. ASVs were identified by selecting the best BLASTn match against the NCBI nucleotide database., Results: Overall, 16 mammal (including human), 14 bird, and seven reptile species were identified in the diet of sylvatic triatomines. Humans were part of the diet of all analyzed triatomine species, and it was detected in 19 sites representing 12.19% of the sequences., Conclusions: Sylvatic triatomine species from Chile feed on a variety of vertebrate species; many of them are detected here for the first time in their diet. Our results highlight that the sylvatic triatomine-human contact is noteworthy. Education must be enforced for local inhabitants, workers, and tourists arriving in endemic areas to avoid or minimize the risk of exposure to Chagas disease vectors., (© 2023. The Author(s).)

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.

Objective: To identify the association between oral health and suspected cognitive impairment in older adults in Chile., Method: Cross-sectional study including 1826 people ≥60 years who participated in the National Health Survey of Chile, 2016-2017. Oral health was evaluated by the number of teeth, presence of caries, use of dental prostheses, self-reported oral health, and pain and/or discomfort in the oral cavity. Cognitive impairment was assessed using the Mini-Mental State Examination (MMSE). The association was evaluated by logistic and linear regression, adjusted for sociodemographic and lifestyle variables., Results: Compared with people without suspicion of cognitive impairment, people with suspected impairment had five fewer teeth (13.4 vs. 8.5 teeth), a much higher difference in women than in men, and a higher frequency of oral pain. Edentulism and fewer teeth were associated with a higher likelihood of suspected cognitive impairment, associations that were not maintained in adjusted models. Oral pain was associated with a higher likelihood of suspected impairment even in the most adjusted model (odds ratio: 1.99; 95% confidence interval [95%CI]: 1.09-3.63). In linear models, an increase of 2% (95%CI: 0.01-0.05) in the MMSE score was observed for each additional tooth., Conclusions: Poor oral health, particularly tooth loss and the presence of pain, was associated with cognitive impairment in older adults in Chile., (Copyright © 2023 SESPAS.

Background: Although the importance of walking for promoting a better cardiometabolic health is widely known (this includes both cardiovascular and metabolic/endocrine systems), there is little knowledge regarding its appropriate pace to provide adults with more cardiometabolic benefits., Aim: To analyze the associations between different walking pace categories and cardiometabolic health markers in the adult Chilean population., Methods: Cross-sectional study. A total of 5520 participants aged 15 to 90 years old from the Chilean National Health Survey (CNHS) 2016-2017 were included. Walking pace categories (slow, average, and brisk) were collected through self-reported methods. Glycaemia, glycosylated hemoglobin (HbA1c), gamma glutamyl transferase (GGT), vitamin D2, vitamin D3, systolic and diastolic blood pressure, and lipid profile (Total, HDL, LDL, VLDL, No HDL cholesterol and triglycerides) were determined using blood sample tests and measured with the standardized methods described in the CNHS 2016-2017., Results: People who had a brisk walking pace were associated with lower levels of glycaemia, HbA1c, GGT, systolic and diastolic blood pressure, and higher vitamin D3 levels compared with those with a slow walking pace. Moreover, people with a brisk walking pace had lower levels of VLDL cholesterol compared with those with a slow walking pace. However, after adjusting the model to include sociodemographic background, nutritional status, and lifestyle variables, the differences remained only for glycaemia, HbA1c and systolic blood pressure levels., Conclusions: A brisk walking pace was associated with better cardiometabolic health markers and lipid profile compared with a slow walking pace.

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.

Introduction: 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.

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.

In Chile, compliance with the Food-Based Dietary Guidelines (GABA) ensures an adequate and ba lanced diet., Objective: To determine compliance with five GABA recommendations and their asso ciations with anthropometric, lifestyle, and metabolic variables, in adolescents aged between 15 and 19 years who participated in the Chilean National Health Survey 2016-2017., Subjects and Method: Cross-sectional study including 355 adolescents. Participants were divided into four groups (fulfilled 0, 1, 2, or ≥ 3 recommendations) using five messages from the GABA (consumption of legumes, fish, dairy products, water, and fruits and vegetables). Associations between GABA and outcome variables (weight, body mass index, waist circumference, physical activity, sleep, and metabolic variables) were investigated using linear regression analyses adjusted by sociodemographic confounders., Results: 5.6% of the adolescents met three or more GABA recommendations. Of the recommendations mea sured, the consumption of water (85%) and legumes (78.7%) presented greater compliance, showing differences between women and men regarding the consumption of legumes (58.6% vs. 86.4%), wa ter (69.6% vs. 91%), and dairy products (92.9% vs. 39.1%). Adolescents with higher compliance with GABA had a better concentration of lower glycemia (p = 0.025). There were no other significant asso ciations between lifestyle and anthropometric measurements., Conclusions: Adolescents who partici pated in this study presented difficulties in adhering to GABA recommendations, thus compromising the maintenance of healthy lifestyles.

Obesity is a worry because it is associated with a greater burden of disease, and it has been shown to be related to the health habits and physical condition of children and adolescents., Objective: To associate physical fitness, screen time, and sleep habits with the different categories of obesity in schoolchildren from the extreme south of Chile., Methods: 583 schoolchildren were included in this cross-sectional analysis. The screen time and sleep habits were measured with the Sleep Self-Report questionnaire, while the physical fitness was assessed with the Alpha Fitness test battery. The Body Mass Index/age (BMI/age) and the Waist-to-Height ratio (WtHr) were used to define adiposity using the following categories: healthy weight/low-risk waist-to-height ratio (H/LR), healthy weight/high-risk waist-to-height ratio (H/HR), overweight/low-risk waist to height ratio (O/LR), and overweight/high-risk waist to height ratio (O/HR)., Results: A considerable number of schoolchildren (23.2%) presented sleep problems, while the mean screen time was 9.3 (95% CI: 8.4; 10.1) hours/day. Schoolchildren classified as H/HR showed better physical fitness than the O/HR group but worse physical fitness than the H/LR group., Conclusions: Significant differences were evidenced in the physical fitness between the adiposity categories, which could open future lines of research concerning the characterization of the healthy weight-obese adiposity categories in children.

Introduction: The melanocortin receptor 4 (MC4R) participates in the control of appetite at the level of the central nervous system, through the leptin-melanocortin pathway. An association between different polymorphisms of the MC4R gene and obesity has been reported. However, there are few studies of the rs483145 single nucleotide polymorphism (SNP) of this gene., Objective: To investigate its prevalence and association with adiposity markers in Chilean adults., Methods: The prevalence of SNP rs483145, of the MC4R gene, was determined in 259 participants of the GENADIO study (genes, environment, diabetes and obesity) by means of real-time polymerase chain reaction (PCR). The association between the risk allele of MC4R (A) and adiposity markers (body weight, body mass index, fat mass percentage, hip circumference, waist circumference, waist-to-hip ratio) was performed by linear regression analysis and adjusted for confusion variables (socio-demographic and physic activity) using three statistical models., Results: It was determined that the prevalence of the risk allele (A) of the SNP rs483145 of the MC4R gene is 24.5% in the Chilean adult population included in this study, without finding an association with any of the adiposity markers studied, both in adjusted and unadjusted models., Conclusion: The presence of the risk allele of SNP rs483145 of the MC4R gene is not associated with adiposity markers in the Chilean adult population studied. New studies with a bigger sample size will be necessary to confirm these results., (Copyright © 2022. Published by Elsevier España, S.L.U.)

Chronic Chagas disease affects humans and animals, involving rural and urban inhabitants. Dogs participate in the maintenance and transmission of Trypanosoma cruzi. The objective of this study was to evaluate the presence of T. cruzi in dogs and their ticks and fleas, in a rural area of Central Chile. Trypanosoma cruzi was detected by PCR both in dogs and ectoparasites. From the blood samples obtained, 57% were infected by T. cruzi, 5.4% of the ticks detected were positive, and all fleas were negative. Additionally, we performed electrocardiograms and found supraventricular arrhythmia in 44% of T. cruzi-positive dogs. Nevertheless, their risk for supraventricular arrhythmias was not higher in infected versus noninfected dogs. Considering the detected infection levels, dogs act as T. cruzi hosts in Central Chile, and ticks could be used as an indicator of infection when blood samples are not available. However, at this point, there is no indication that these ticks could pass on the parasite to another host. Periodic ectoparasitic treatment of pets should reduce the chance of vectorial transmission of T. cruzi and improve canine health; however, this is an uncommon practice among rural communities, so governmental programs are encouraged to tackle this problem., (© 2021 Royal Entomological Society.)

The protozoan Trypanosoma cruzi, the causative agent of Chagas disease, is transmitted by infected feces or consumption of blood-sucking triatomine insects to several mammalian orders including Chiroptera. In Chile, the distribution of several insectivorous and one hematophagous bat species overlaps with those of triatomine vectors, but the T. cruzi infection status of local chiropterans is unknown. In 2018, we live-captured bats from two protected areas in Chile to collect plagiopatagium tissue, feces and perianal swab samples, in search for T. cruzi-DNA by real time PCR assays using species-specific primers. In Pan de Azúcar island (∼26°S), we examined a roost of Desmodus rotundus (common vampire bat) and sampled tissue from 17 individuals, detecting T. cruzi-DNA in five of them. In Las Chinchillas National Reserve (∼31°S), we examined two roosts of Histiotus montanus (small big-eared brown bat), collecting feces or perianal swab samples from eight individuals, detecting T. cruzi-DNA in four of them. This is the first report of T. cruzi-DNA evidence in bat species from Chile. Both vector-borne and oral transmission are potential infection routes that can explain our results. Further investigation is needed for a better understanding of the role of bats in the T. cruzi transmission cycle., (Copyright © 2021. Published by Elsevier B.V.)

Objective: To study the association of SLC16A11 gene variants with obesity and metabolic markers in nondiabetic Chilean adults., Methods: This cross-sectional study included 263 non-diabetic adults. The genotype of the rs75493593 polymorphism of SLC16A11 gene was performed by real-time PCR. It's association with adiposity markers (body weight, BMI, waist circumference and fat mass percentage), metabolic markers (glucose, insulin, HOMA IR , leptin, total cholesterol, LDLc, HDLc, triglycerides, ALT, GGT and hsCRP) and blood pressure was analyzed by linear regression., Results: The minor allele (T) of the SLC16A11 gene (rs75493593) has a frequency of 29.7% among Chileans. Risk genotypes (GT and TT) were associated with a significant 1.49 mU/l increase in plasmatic insulin for each copy of the minor allele (95% CI: 0.12, 2.87, p < 0.05). This association remained significant after adjusting for socio-demographic variables, physical activity and smoking (1.36 mU/l, 95% CI: 0.16, 2.58 p < 0.05), but was lost when BMI was included as a confounding factor. Higher BMI was also significantly associated with polymorphic genotypes in SLC16A11 , independent of socio-demographic variables., Conclusion: The minor allele of the SLC16A11 gene (T) is highly prevalent among Chileans and is associated with increased insulin and BMI in nondiabetic individuals. These findings suggest that the genetic variant in SLC16A11 is not only associated with type 2 diabetes as previously shown in Mexicans, but is also related to early metabolic alterations in healthy subjects that may lead to type 2 diabetes.

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.

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.

We estimated the proportion and number of deaths from non-communicable diseases (NCD) attributable to high body mass index (BMI) in Chile in 2018. We used data from 5927 adults from a 2016-2017 Chilean National Health Survey to describe the distribution of BMI. We obtained the number of deaths from NCD from the Ministry of Health. Relative risks (RR) and 95% confidence intervals per 5 units higher BMI for cardiovascular disease, cancer, and respiratory disease were retrieved from the Global BMI Mortality Collaboration meta-analyses. The prevalences of overweight and obesity were 38.9% and 39.1%, respectively. We estimated that reducing population-wide BMI to a theoretical minimum risk exposure level (mean BMI: 22.0 kg/m 2 ; standard deviation: 1) could prevent approximately 21,977 deaths per year (95%CI 13,981-29,928). These deaths represented about 31.6% of major NCD deaths (20.1-43.1) and 20.4% of all deaths (12.9-27.7) that occurred in 2018. Most of these preventable deaths were from cardiovascular diseases (11,474 deaths; 95% CI 7302-15,621), followed by cancer (5597 deaths; 95% CI 3560-7622) and respiratory disease (4906 deaths; 95% CI 3119-6684). A substantial burden of NCD deaths was attributable to high BMI in Chile. Policies and population-wide interventions are needed to reduce the burden of NCD due to high BMI in Chile., (© 2021.

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.

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.

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.

Objective: The aim of this study was to identify which anthropometric measurement (body mass index [BMI], waist circumference [WC], or waist-to-height ratio [WHtR]) is a better predictor of type 2 diabetes and hypertension in the Chilean population., Methods: The study included 13 044 participants (59.7% women) from the Chilean National Health Surveys conducted in 2003, 2009-2010, and 2016-2017. BMI, WC, and WHtR were the anthropometric measurements evaluated. Hypertension was defined as systolic blood pressure ≥140 mm Hg and diastolic blood pressure ≥90 mm Hg or on medication for hypertension. Diabetes was defined as fasting glucose ≥7 mmol/L or on medication for diabetes. The receiver operating characteristics (ROC) curve and the area under curve (AUC) were computed to derive the specificity and sensitivity using a bootstrapping approach., Results: Compared with BMI and WC, WHtR was the anthropometric measurement with the highest AUC curve in both sexes for hypertension (AUC for women: 0.70; 95% confidence interval [CI], 0.67-0.73; AUC for men: 0.71; 95% CI, 0.69-0.74) and diabetes (AUC for women: 0.71; 95% CI, 0.66-0.77; AUC for men: 0.71; 95% CI, 0.67-0.76). The sex-specific cutoff points of WHtR to predict hypertension were 0.59 and 0.55 for women and men, respectively. Those used to predict diabetes were 0.60 and 0.58 for women and men, respectively., Conclusion: WHtR was a better predictor of hypertension and diabetes than BMI and WC in Chile. The definition of cutoff points specific for the Chilean population could be implemented in future screening programs aiming to identify high-risk individuals., (Copyright © 2020 Elsevier Inc.

Background: Handgrip strength is an indicator of frailty in older people., Aim: To determine the prevalence of low handgrip strength in older Chilean adults., Material and Methods: A cross-sectional analysis of 244 individuals aged 60 years or more, participating in the 2016-2017 Chilean National Health Survey, was carried out. Handgrip strength was evaluated by a hand dynamometer and low grip strength was determined as a grip strength ≤ 15 kg and ≤ 27 kg for women and men, respectively., Results: Twenty nine percent of participants had low grip strength. The average grip strength among 60-year-old men and women was 34.7 and 22.1 kg, respectively. These figures decreased to 28.8 kg and 17.2 kg among 90-year-old men and women, respectively. The prevalence of low grip strength in men and women aged 60 years was 18%. In 90-year-old men and women, these figures increased to 79% and 56.3%, respectively., Conclusions: The prevalence of low grip strength increased substantially with age.

Objective: To identify sex-specific cut-off points for waist circumference (WC) in the definition of metabolic syndrome (MetS) for the Chilean adult population., Design: MetS was defined as the presence of at least two out of four of the following criteria: TAG ≥1·7 mmol/l; HDL-cholesterol: <1·3 mmol/l in women and <1·0 mmol/l in men; systolic blood pressure ≥130 mmHg and/or diastolic blood pressure ≥85 mmHg; and fasting glucose ≥ 5·6 mmol/l or current treatment for diabetes. The receiver operating characteristics curve and the AUC were computed to derive the specificity and sensitivity using bootstrapping (10 000 iterations restricted to have at least between 40 and 60 % of the original population). The optimal cut-off point for the Chilean population was computed by sex., Setting: A representative sample of the Chilean population aged ≥15 years., Participants: 8182 participants (60 % women) from the three available Chilean National Health Surveys conducted in 2003, 2009-2010 and 2016-2017., Results: WC had a good predictive ability for MetS (AUC for men 0·74 (95 % CI 0·72, 0·76); AUC for women 0·71 (95 % CI 0·68, 0·73)). The optimal cut-off points for WC, in the definition of MetS, were 92·3 cm (95 % CI 90·5, 94·4) and 87·6 cm (95 % CI 85·8, 92·1) for men and women, respectively., Conclusions: The mentioned cut-off points should be used for WC in the definition of MetS in Chile. As a result, the current recommendation (WHO/International Diabetes Federation) for WC, in the identification of MetS, is not supported by these findings in a representative sample of the Chilean adult population.

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.

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: To identify modifiable risk factors that contribute to cancer holds important public health relevance for setting up prevention strategies. Therefore, the aim of this study was to estimate the proportion of cancer cases and deaths attributable to alcohol consumption, high body mass index (BMI), low fruits and vegetables consumption, lack of physical activity, tobacco smoking, and passive smoking in Chile in 2018., Methods: We retrieved data from a national representative survey to describe the distribution of six lifestyle risk factors. Relative risks of each risk factor-cancer pair were obtained from published meta-analysis and pooled cohort studies. Cancer cases and deaths were obtained from the GLOBOCAN 2018., Results: Nearly 30% of all cancer cases (15,097 out of 50,320 cases) and 36% of all cancer deaths (10,155 out of 28,010 deaths) in Chile in 2018 were attributable to lifestyle risk factors. Smoking and high BMI accounted for most of the cancer cases (9232 and 4394, respectively) and deaths (6868 and 2572). The cancer burden of other lifestyle risk factors varied by sex. In men, the proportion of all cancer cases attributed to alcohol were 3.7% compare to 2.0% for women. Cancers cases and deaths of the larynx, lung, oral/cavity, esophagus and bladder could be at least halved if lifestyle risk factors were eliminated., Conclusion: Smoking and high BMI were the leading causes of preventable cancer cases and deaths within the six lifestyles factors considered. Cancer prevention strategies should consider evidence-based interventions and public policies to encourage the adoption of a healthier lifestyle.

Background: Walking pace is a well-known indicator of physical capability, but it is also a strong predictor of type 2 diabetes (T2D). However, there is a lack of evidence on the association between walking pace and T2D, specifically, within developing countries such as Chile., Aim: To investigate the association between self-reported walking pace and T2D in the Chilean adult population., Methods: 5520 Chilean participants (aged 15 to 90 years, 52.1% women) from the Chilean National Health Survey 2016-2017 were included in this cross-sectional study. Both walking pace (slow, average, and brisk) and diabetes data were collected through self-reported methods. Fasting blood glucose (reported in mg/dl) and glycosylated haemoglobin A (HbA1c) scores were determined via blood exams., Results: In the unadjusted model, and compared to people who reported a slow walking pace, those with average and brisk walking pace had lower blood glucose levels (β = -7.74 mg/dL (95% CI: -11.08 to -4.40) and β = -11.05 mg/dL (95% CI: -14.36 to -7.75), respectively) and lower HbA1c (β = -0.34% (95% CI: -0.57 to -0.11) and β= -0.72% (95% CI: -0.94 to -0.49)), respectively. After adjusting for sociodemographic, Body Mass Index and lifestyle factors, the association between glycaemia and HbA1c remained only for brisk walkers. Both the average and brisk walker categories had lower odds of T2D (OR: 0.59 (95% CI: 0.41 to 0.84) and (OR 0.48 (95% CI: 0.30 to 0.79), respectively)., Conclusion: Brisk walkers were associated with lower blood glucose and HbA1c levels. Moreover, average to brisk walking pace also showed a lower risk for T2D.

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.

Background: Sugar intake is a risk factor for the development of obesity., Aim: To investigate the association between total sugar intake and obesity markers in Chilean adults., Material and Methods: This cross-sectional study included 396 participants of the GENADIO study. Anthropometric measurements (body weight, body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio, and % body fat) were measured through standardized protocols. Total sugar intake was determined from a 7-days weighted food daily. Sugar intake expressed in g/day was categorized into quartiles., Results: Higher sugar intake was associated with a higher BMI, WC and HC but not with body fat %. One quartile increment in sugar intake was associated with 1.50 kg [95% confidence interval (CI): 0.49; 2.50] higher body weight, 0.34 kg/m2 [95% CI: 0.01; 0.69] higher BMI, 1.23 cm [95% CI: 0.11; 2.34] higher WC, 1.39 cm [95% CI: 0.28; 2.50] higher HC and 0.02 the waist-to-hip ratio [95% C: 0.01; 0.02]., Conclusions: Total sugar intake was associated with higher adiposity levels in these Chilean adults.

Introduction: Obesity is considered a chronic inflammatory disease with an important genetic component. Although several studies have reported an association between the FTO (fat-mass associated gene) and adiposity in children, there is limited evidence in the Chilean population., Objective: To deter mine the association between the polymorphism rs9939609 of the FTO gene and markers of adipo sity in Chilean children., Patients and Method: Cross-sectional study which included 361 children aged between 6 and 11 years (50% were girls). Between March and June 2008, clinical data and blood sample collection was carried out. The rs9939609 single-nucleotide polymorphism (SNP) of the FTO gene, was determined using the genomic DNA extracted from leukocytes, using the QIAamp DNA Blood Mini Kit (Qiagen GmbH, Hilden, Germany).The adiposity markers included were body mass index (BMI), waist circumference (WC), body fat, and WC/H index; which were later compared adjusted by sex, age, and Tanner stage. Linear regression analyses were conducted to detect the association between the polymorphism and obesity markers., Results: After adjusting the models by age, sex, and Tanner stage, we found a significant association between the polymorphism and markers of adiposity. For each extra copy of the risk allele, we found an increase of 2.47 kg body weight (95% CI: 1.39-3.55); 1.06 kg/m2 BMI (95% CI: 0.56-1.54); 2.55 cm WC, (95% CI: 1.26-3.85); and 1.98% body fat (95% CI: 0.78-3.19). When converting adiposity markers to z-score, we found that WC/height index shows the strongest association with the risk allele FTO., Conclusion: This study supports the association between the rs9939609 SNP of the FTO gene and overall and central adiposity markers in Chilean children.

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.

Background: Active travel has been suggested as a feasible way of increasing physical activity levels. Although international studies have demonstrated its effect over different health outcomes and adiposity, there is still limited evidence on this topic in developing countries, such as Chile., Aim: To investigate the associations between different types of travelling and markers of obesity in the Chilean adult population., Methods: 5411 participants from the Chilean National Health Survey 2016-2017 (CNHS) were included in this study. Active travel was assessed using a questionnaire. Car commuters, public transport (PT), walking and cycling were the four forms of travelling assessed. Bodyweight, body mass index and waist circumference were used as markers of adiposity., Results: Compared to car travellers, body weight, WC and BMI levels were lower for PT walking and cycling travellers. The odds for obesity (Odds ratio (OR): 0.41 (95% CI: 0.28; 0.61 p ≤ 0.001) were lower for walking and the odds (OR: 0.56 (95%CI: 0.35; 0.89 p = 0.014) for central obesity were significantly lower for cyclist in comparison to car travellers. Additionally, participation in any form of active travel (walking or cycling) was low, with only 20.9% of the population reporting being active travellers., Conclusion: Active travel, such as walking and cycling, was associated with lower adiposity levels in the Chilean adult population. Promoting active travel could be a feasible strategy to tackle the high prevalence of obesity and physical inactivity in the Chilean population., Competing Interests: The authors declare that they have no conflict of interest.

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: 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.

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.
