Background and Aims: in the Southern Cone of Latin America, previous studies have shown that blood hypertension is one of the most significant risk factor for cardiovascular disease, and diet plays a fundamental role. We analyzed the cross-sectional relationship between dietary patterns (DP) and blood pressure values in people involved in the CESCAS I Study.Methods and Results: the participants (n = 4626) were derived from randomly selected samples in 4 cities (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay). To define DP, a food-frequency questionnaire was applied and principal component analysis was performed. Blood pressure was determined according to standardized guidelines. A multivariate regression model was developed to determine the association between each DP and blood pressure values, according to the quartile (Q) of adherence to DP. Two predominant DP were detected, Prudent (PDP, higher consumption of fruits, vegetables, legumes, whole grains, fish, seafood and nuts) and Western (WDP, higher consumption of red and processed meats, dressings, sweets, snacks and refined grains). A significant inverse association was found between adherence to PDP and systolic and diastolic blood pressure (-1.85 and -1.29 mmHg for Q4 vs Q1, respectively). Adherence to WDP was positively associated with systolic blood pressure (2.09 mmHg for Q4 vs Q1).Conclusion: the WDP detected in the studied population is positively associated with higher levels of blood pressure, while greater adherence to healthy DP has a positive impact on blood pressure.

Introduction: Alcohol consumption is a risk factor for morbidity and mortality globally. Consumption levels in Southern Latin America are among the highest in the world. Objectives: To describe consumption patterns and adherence to guidelines in the general adult population of Southern Latin America, as well as exploration of reasons for alcohol cessation and the advising role of the health worker in this decision. Methods: In 7,520 participants from the Centro de Excelencia en Salud Cardiovascular para el America del Sur (CESCAS) cohort, consumption patterns were described and the proportion excessive drinkers (i.e. >7 units/week for women and >14 for men or binge drinking: >4 (women) or >5 (men) units at a single occasion) was calculated. Former drinkers were asked if they had quit alcohol consumption on the advice of a health worker and/or because of health reasons. Furthermore, among former drinkers, multivariable logistic regression analysis was performed to assess which participant characteristics were independently associated with the chance of quitting consumption on a health worker's advice. Results: Mean age was 54.8 years (SD = 10.8), 42% was male. Current drinking was reported by 44.6%, excessive drinking by 8.5% of the population. In former drinkers, 23% had quit alcohol consumption because of health reasons, half of them had additionally quit on the advice of a health worker. The majority of former drinkers however had other, unknown, reasons. When alcohol cessation was based on a health worker's advice, sex, country of residence, educational status and frequency of visiting a physician were independent predictors. Conclusion: In this Southern American population-based sample, most participants adhered to the alcohol consumption guidelines. The advising role of the health worker in quitting alcohol consumption was only modest and the motivation for the majority of former drinkers remains unknown. A more detailed assessment of actual advice rates and exploration of additional reasons for alcohol cessation might be valuable for alcohol policy making. [ABSTRACT FROM AUTHOR]

Background Using data from general adult population, this study aims to describe epidemiology of alcohol consumption patterns and their association with cardiovascular risk. Methods CESCAS I is a population-based study from four mid-sized cities in Argentina, Chile and Uruguay. Associations between diabetes, hypertension, dyslipidemia, cardiovascular disease (CVD) risk and history of CVD and drinking patterns were assessed using crude prevalence odds ratios (ORs) and adjusted OR. Results A total of 37.2% of the studied population never drank and 18.3% reported to be former drinkers. Among current drinkers, moderate drinking was the most frequent pattern (24.2%). For women with light and moderate consumption, the odds of having >20% CVD risk was ~40% lower than that of never drinkers. The odds of having a history of CVD was 50% lower in those with moderate consumption. For men with heavy consumption, the odds of having >20% CVD risk was about twice as high as for never drinkers. Conclusions A harmful association was observed between heavy drinking and having >20% CVD risk for men. However, for women, an apparently protective association was observed between light and moderate drinking and having >20% CVD risk and between moderate drinking and having a history of CVD.

Background: Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide. The study aimed to determine and compare the prevalence of COPD in the general population aged 45-74 years old according to fixed ratio and lower limit of normal (LLN) thresholds in four cities in the Southern Cone of Latin America.Methods: The Pulmonary Risk in South America (PRISA) study used a 4-stage stratified sampling method to select 5814 participants from 4 cities in the Southern Cone of Latin America (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay). Data on demographic information, medical history, risk factors, pre-bronchodilator and post-bronchodilator spirometry were obtained using a standard protocol. According to GOLD, COPD was defined as a post-bronchodilator ratio of forced expiratory volume in one second (FEV1) over forced vital capacity (FVC) less than 70%. The LLN threshold was defined as the lower fifth percentile for predicted FEV1/FVC, and was evaluated as an alternative COPD definition.Results: Overall COPD prevalence was 9.3% (95% CI 8.4, 10.2%), and men had a higher prevalence [11.8% (95% CI 10.3, 13.3%)] than women [7.3% (95% CI 6.2, 8.3%)] with the fixed ratio. Overall COPD prevalence using LLN was 4.7% (95% CI 4.1, 5.3%), higher in men: 5.8% (95% CI 4.7, 6.8%) than women: 3.9% (95% CI 3.1, 4.7%). COPD prevalence was significantly higher among those who were older, had Conclusions: First, COPD and its risk factors are highly prevalent in the general population of Argentina, Chile, and Uruguay. Second, the prevalence of COPD by LLN criterion was significantly lower with lesser degrees of severity compared to fixed ratio of FEV1/FVC. Implementing LLN criterion instead of fixed ratio of FEV1/FVC may reduce the risk of over-diagnosis of COPD, although further prognostic studies of COPD adverse outcomes should be conducted using both definitions. Third, these data suggest that national efforts on the prevention, treatment, and control of COPD should be a public health priority in the Southern Cone of Latin America. [ABSTRACT FROM AUTHOR]

Aims: To determine the prevalence, treatment and control of diabetes mellitus (DM) and impaired fasting glucose (IFG) as well as associated factors in the adult population of four cities of the Southern Cone of Latin America (SCLA). Methods: This is a cross-sectional population-based study that included 7407 adults between 35 and 74 years old in four cities of the SCLA: Temuco (Chile), Marcos Paz and Bariloche (Argentina), and Pando-Barros Blancos (Uruguay). DM was defined as fasting plasma glucose ≥126 mg/dL or self-reported history of diabetes. Awareness, treatment, and control of DM were defined as subjects self-reporting a DM previous diagnosis, the use of a prescription medication or nonpharmacological intervention for DM, and fasting plasma glucose <126 mg/dl, respectively. Results: Prevalence of DM varied among cities, between 8.4% in Bariloche and 14.3% in Temuco. Prevalence of IFG varied at different sites, from 3.5% in Barros Blancos to 6.8% in Marcos Paz. Of the total number of people with diabetes, 20% were newly diagnosed at the time of the study. Overall, 79.8% of patients with diabetes were aware of their condition. The treatment and control rate were 58.8% and 46.2%, respectively. Older age, family history of diabetes, lower educational attainment, overweight, obesity, central obesity, low physical activity, hypertension, hypercholesterolemia and hypertriglyceridemia were all significantly associated with an increased risk of diabetes. Conclusions: The prevalence of DM and IFG in the adult population of the SCLA is high and varies among cities. These conditions represent a public health challenge since the rates of awareness, treatment, and control are still low. [ABSTRACT FROM AUTHOR]

The maximum content of sodium in selected processed foods (PF) in Argentina was limited by a law enacted in 2013. Data about intake of these and other foods are necessary for policy planning, implementation, evaluation, and monitoring. We examined data from the CESCAS I population-based cohort study to assess the main dietary sources among PF and frequency of discretionary salt use by sex, age, and education attainment, before full implementation of the regulations in 2015. We used a validated 34-item FFQ (Food Frequency Questionnaire) to assess PF intake and discretional salt use. Among 2127 adults in two Argentinean cities, aged 35-76 years, mean salt intake from selected PFs was 4.7 g/day, higher among male and low education subgroups. Categories of foods with regulated maximum limits provided near half of the sodium intake from PFs. Use of salt (always/often) at the table and during cooking was reported by 9% and 73% of the population, respectively, with higher proportions among young people. Reducing salt consumption to the target of 5 g/day may require adjustments to the current regulation (reducing targets, including other food categories), as well as reinforcing strategies such as education campaigns, labeling, and voluntary agreement with bakeries.

Background: Obesity is a major determinant of cardiovascular disease in South America. However, population-based data are limited. Methods: A total of 7,524 women and men, aged 35 to 74 years old, were randomly selected from 4 cities in the Southern Cone of Latin America between February 2010 and December 2011. Obesity clinical measurements and cardiovascular risk factors were measured using standard methodology. Results: The prevalence of obesity and central obesity were 35.7% and 52.9%, respectively. The prevalence of obesity and central obesity were higher in women, and even higher in women with lower education compared with women with higher education. In men and women obesity was associated with a higher prevalence of diabetes, odds ratio (OR) 2.38 (95% Confidence Interval [CI]: 1.86 to 3.05) and 3.01 (95%CI 2.42 to 3.74) respectively, hypertension (OR 2.79 (95%CI 2.32 to 3.36) and 2.40 (95%CI 2.05 to 2.80) respectively, dyslipidemia (OR 1.83 (95%CI 1.50 to 2.24) and 1.69 (95%CI 1.45 to 1.98), respectively, low physical activity (OR 1.38(95%CI 1.14 to 1.68) and 1.38 (95%CI 1.18 to 1.62) respectively and a lower prevalence of smoking (OR, 0.65 (95%CI 0.53 to 0.80) and 0.58(95%CI 0.48 to 0.70) respectively. Conclusions: Obesity and central obesity are highly prevalent in the general population in the Southern Cone of Latin America and are strongly associated with cardiovascular risk factor prevalence. These data suggest that efforts toward prevention, treatment, and control of obesity should be a public health priority in the Southern Cone of Latin America. [ABSTRACT FROM AUTHOR]

To examine the relationship between suicidal ideation (SI) and cardiovascular disease (CVD) in the general adult population of four cities in the Southern Cone of Latin America (Argentina, Uruguay, Chile) and the role that depression, stressful life events (SLEs) and physical functional impairment may play in this association. A population-based cross-sectional study was conducted among 7524 adults between 35 and 74 years old, randomly selected. History of CVD included acute myocardial infarction, stroke and central or peripheral revascularization. SI in the past two weeks was measured using the last item of the Patient Health Questionnaire (PHQ-9), quality of life was assessed with the 12-item Short Form Survey (SF-12), and having experience of a SLE was determined by asking participants whether they had experienced at least one of a list of events in the past year. Multiple logistic regression was used to examine the association between SI and CVD overall and by sex. The prevalence of SI was 8.3% (95% CI = 7.5, 9.0) and twice as high among women than men (11.1% vs. 5.1%). History of CVD was associated with almost twice the odds of SI (OR = 1.9, 95% CI = 1.5, 2.4). This association remained strong and significant after adjusting for potential confounders (OR = 1.8, 95% CI = 1.2, 2.7). Three additional models were tested to further adjust for depression severity, functional impairment, and SLEs separately. Adjustment for depression severity yielded no association between CVD and SI (OR = 1.1, 95% CI = 0.6, 1.7), adjustment for functional impairment yielded a marginal statistically significant association (OR = 1.5; 95% CI = 1.0, 2.4) and adjustment for SLE didn't modify either the magnitude or the statistical significance of the association. There is a significant association between SI and CVD, particularly among women, which may be driven, at least in part, by depression and physical functional impairment. [ABSTRACT FROM AUTHOR]

Introduction: Current recommendations for cardiovascular disease (CVD) prevention are guided CVD risk classification. This study aims to analyze the level of compliance with pharmacological and non-pharmacological recommendations outlined in the World Health Organization (WHO) CVD prevention clinical practice guideline within the general population of two cities in Argentina., Methods: We analyzed the compliance with preventive recommendations from the WHO 2007 Guidelines for Management of Cardiovascular Risk in two cities of Argentina participating in the CESCAS population-based study in the Southern Cone of Latin America., Results: 3990 participants were included. Considering the WHO recommendations, the use of antiplatelet medication was 5.6% (95% CI 3.5, 8.9) in primary prevention and 20.5% (95%= CI 16.0, 25.9) in secondary prevention. Regarding lipid-lowering medication, it was 6.7% (CI 95%= 4.4, 10.1) and 15.4% (CI 95%= 11.6, 20.1), respectively. As per non-pharmacological recommendations in the general population: low intake of fruit and vegetables was 78.4% (CI 95%= 76.8, 79.9); low physical activity was 26.9% (CI 95%= 25.3, 28.5), current cigarette smoking was 28.3% (CI 95%= 26.6, 30.0), overweight/obesity was 73.9% (CI 95%= 72.3, 75.6), and excessive alcohol intake was 2.6% (CI 95%= 2.1, 3.4)., Conclusions: It was observed a significantly low compliance with pharmacological and non-pharmacological recommendations for CVD prevention in the general population of two cities in Argentina. Urgent efforts are needed to improve compliance to cardiovascular preventive recommendations promoted by CPG, especially in Low- and Middle- Income Countries., (Universidad Nacional de Córdoba)

Background: Elevated Lipoprotein(a) [Lp(a)] is independently associated with increased cardiovascular disease (CVD) risk. There are discrepancies regarding its epidemiology due to great variability in different populations. This study aimed to evaluate the prevalence of elevated Lp(a) in people with moderate CVD risk and increased LDL-c and to determine the association between family history of premature CVD and elevated Lp(a)., Methods: Random subjects from the CESCAS population-based study of people with moderate CVD risk (Framingham score 10-20 %) and LDL-c ≥ 130 mg/dL, were selected to evaluate Lp(a) by immunoturbidimetry independent of the Isoforms variability. The association between family history of premature CVD and elevated Lp(a) was evaluated using multivariate logistic regression models. Elevated Lp(a) was defined as Lp(a) ​​≥ 125 nmol/L., Results: Lp(a) was evaluated in 484 samples; men = 39.5 %, median age = 57 years (Q1-Q3: 50-63), mean CVD risk = 14.4 % (SE: 0.2), family history of premature CVD = 11.2 %, Lp(a) median of 21 nmol/L (Q1-Q3: 9-42 nmol/L), high Lp(a) = 6.1 % (95 % CI = 3.8-9.6). Association between family history of premature CVD and elevated Lp(a) in total population: OR 1.31 (95 % CI = 0.4, 4.2) p = 0.642; in subgroup of people with LDL-c ≥ 160 mg%, OR 4.24 (95 % CI = 1.2, 15.1) p = 0.026., Conclusions: In general population with moderate CVD risk and elevated LDL-c from the Southern Cone of Latin America, less than one over ten people had elevated Lp(a). Family history of premature CVD was significantly associated with the presence of elevated Lp(a) in people with LDL-c ≥ 160 mg/dL., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Authors.)

Background: Hypertension is the leading global preventable risk factor for premature death. While hypertension prevalence has been declining in high-income countries, it has increased continuously in low- and middle-income countries., Methods: We conducted a cross-sectional survey in 7,524 women and men aged 35-74 years from randomly selected samples in 4 cities (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay) in 2010-2011. Three blood pressure (BP) measurements were obtained by trained observers using a standard mercury sphygmomanometer. Hypertension was defined as a mean systolic BP ≥140mm Hg and/or diastolic BP ≥90mm Hg and/or use of antihypertensive medications., Results: An estimated 42.5% of the study population (46.6% of men and 38.7% of women) had hypertension and an estimated 32.5% (36.0% of men and 29.4% of women) had prehypertension. Approximately 63.0% of adults with hypertension (52.5% of men and 74.3% of women) were aware of their disease condition, 48.7% (36.1% of men and 62.1% of women) were taking prescribed medications to lower their BP, and only 21.1% of all hypertensive patients (13.8% of men and 28.9% of women) and 43.3% of treated hypertensive patients (38.1% of men and 46.5% of women) achieved BP control., Conclusions: This study indicates that the prevalence of hypertension is high while awareness, treatment, and control are low in the general population in the Southern Cone of Latin America. These data call for bold actions at regional and national levels to implement effective, practical, and sustainable intervention programs aimed to improve hypertension prevention, detection, and control., (© American Journal of Hypertension, Ltd 2016.
