"Super-Spreaders" and Person-to-Person Transmission of Andes Virus in Argentina.

BACKGROUND: From November 2018 through February 2019, person-to-person transmission of Andes virus (ANDV) hantavirus pulmonary syndrome occurred in Chubut Province, Argentina, and resulted in 34 confirmed infections and 11 deaths. Understanding the genomic, epidemiologic, and clinical characteristics of person-to-person transmission of ANDV is crucial to designing effective interventions. METHODS: Clinical and epidemiologic information was obtained by means of patient report and from public health centers. Serologic testing, contact-tracing, and next-generation sequencing were used to identify ANDV infection as the cause of this outbreak of hantavirus pulmonary syndrome and to reconstruct person-to-person transmission events. RESULTS: After a single introduction of ANDV from a rodent reservoir into the human population, transmission was driven by 3 symptomatic persons who attended crowded social events. After 18 cases were confirmed, public health officials enforced isolation of persons with confirmed cases and self-quarantine of possible contacts; these measures most likely curtailed further spread. The median reproductive number (the number of secondary cases caused by an infected person during the infectious period) was 2.12 before the control measures were enforced and decreased to 0.96 after the measures were implemented. Full genome sequencing of the ANDV strain involved in this outbreak was performed with specimens from 27 patients and showed that the strain that was present (Epuyén/18-19) was similar to the causative strain (Epilink/96) in the first known person-to-person transmission of hantavirus pulmonary syndrome caused by ANDV, which occurred in El Bolsón, Argentina, in 1996. Clinical investigations involving patients with ANDV hantavirus pulmonary syndrome in this outbreak revealed that patients with a high viral load and liver injury were more likely than other patients to spread infection. Disease severity, genomic diversity, age, and time spent in the hospital had no clear association with secondary transmission. CONCLUSIONS: Among patients with ANDV hantavirus pulmonary syndrome, high viral titers in combination with attendance at massive social gatherings or extensive contact among persons were associated with a higher likelihood of transmission.

Cost-effectiveness of COVID-19 vaccination in Latin America and the Caribbean: an analysis in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, and Peru.

OBJECTIVE: Our study analyzes the cost-effectiveness of the COVID-19 vaccination campaigns in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, and Peru. METHODS: Using a previously published SVEIR model, we analyzed the impact of a vaccination campaign (2021) from a national healthcare perspective. The primary outcomes were quality adjusted life years (QALYs) lost and total costs. Other outcomes included COVID-19 cases, hospitalizations, deaths, and life years. We applied a discount rate of 3% for health outcomes. We modeled a realistic vaccination campaign in each country (the realistic country-specific campaign). Additionally, we assessed a standard campaign (similar, "typical" for all countries), and an optimized campaign (similar in all countries with higher but plausible population coverage). One-way deterministic sensitivity analyses were performed. FINDINGS: Vaccination was health improving as well as cost-saving in almost all countries and scenarios. Our analysis shows that vaccination in this group of countries prevented 573,141 deaths (508,826 standard; 685,442 optimized) and gained 5.07 million QALYs (4.53 standard; 6.03 optimized). Despite the incremental costs of vaccination campaigns, they had a total net cost saving to the health system of US$16.29 billion (US$16.47 standard; US$18.58 optimized). The realistic (base case) vaccination campaign in Chile was the only scenario, which was not cost saving, but it was still highly cost-effective with an ICER of US$22 per QALY gained. Main findings were robust in the sensitivity analyses. INTERPRETATION: The COVID-19 vaccination campaign in seven Latin American and Caribbean countries -that comprise nearly 80% of the region- was beneficial for population health and was also cost-saving or highly cost-effective.

Previous tuberculosis disease as a risk factor for chronic obstructive pulmonary disease: a cross-sectional analysis of multicountry, population-based studies.

BACKGROUND: Risk factors for COPD in high-income settings are well understood; however, less attention has been paid to contributors of COPD in low-income and middle-income countries (LMICs) such as pulmonary tuberculosis. We sought to study the association between previous tuberculosis disease and COPD by using pooled population-based cross-sectional data in 13 geographically diverse, low-resource settings. METHODS: We pooled six cohorts in 13 different LMIC settings, 6 countries and 3 continents to study the relationship between self-reported previous tuberculosis disease and lung function outcomes including COPD (defined as a postbronchodilator forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) below the lower limit of normal). Multivariable regressions with random effects were used to examine the association between previous tuberculosis disease and lung function outcomes. RESULTS: We analysed data for 12 396 participants (median age 54.0 years, 51.5% male); 332 (2.7%) of the participants had previous tuberculosis disease. Overall prevalence of COPD was 8.8% (range 1.7%-15.5% across sites). COPD was four times more common among those with previous tuberculosis disease (25.7% vs 8.3% without previous tuberculosis disease, p<0.001). The adjusted odds of having COPD was 3.78 times higher (95% CI 2.87 to 4.98) for participants with previous tuberculosis disease than those without a history of tuberculosis disease. The attributable fraction of COPD due to previous tuberculosis disease in the study sample was 6.9% (95% CI 4.8% to 9.6%). Participants with previous tuberculosis disease also had lower prebronchodilator Z-scores for FEV1 (-0.70, 95% CI -0.84 to -0.55), FVC (-0.44, 95% CI -0.59 to -0.29) and the FEV1:FVC ratio (-0.63, 95% CI -0.76 to -0.51) when compared with those without previous tuberculosis disease. CONCLUSIONS: Previous tuberculosis disease is a significant and under-recognised risk factor for COPD and poor lung function in LMICs. Better tuberculosis control will also likely reduce the global burden of COPD.

Health care access and health-related quality of life among people with diabetes in the Southern Cone of Latin America-a cross-sectional analysis of data of the CESCAS I study.

PURPOSE: Little is known on the association of health care access and health-related quality of life (HRQoL) in people with diabetes in the Southern Cone of Latin America (SCLA). METHODS: We analyzed data of 1025 participants of CESCAS I. To determine HRQoL, we used the SF-12 physical (PCS-12) and mental component summary (MCS-12). We compared four groups regarding HRQoL: (a) insured people without self-reported barriers to health care, (b) uninsured people without self-reported barriers to health care, (c) insured people with self-reported barriers to health care, and (d) uninsured people with self-reported barriers to health care. We conducted linear regressions with PCS-12 and MCS-12 as outcome. We adjusted for sociodemographic and disease-related factors and having access to a primary physician. RESULTS: In the first group, there were 407, in the second 471, in the third 44, and in the fourth group 103 participants. Compared to the first group, PCS-12 was 1.9 points lower (95% Confidence Interval, CI: - 3.5, - 0.3) in the second, 4.5 points (95% CI: - 8.1, - 1) lower in the third, and 6.1 points lower (95% CI: - 8.7, - 3.6) in the fourth group. Compared to the first group, MCS-12 was 0.6 points lower (95% CI: - 2.7, 1.4) in the second, 4.8 points lower (95% CI: - 9.3, - 0.3) in the third, and 5.8 points lower (95% CI: - 9.1, - 2.5) in the fourth group. CONCLUSION: In the SCLA, impeded access to care is common in people with diabetes. Self-reported barriers to care may be more important than insurance status in determining HRQoL.

Dietary patterns and blood pressure in Southern Cone of Latin America.

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.

Development of physical activity and food built environment quality indicators for chronic diseases in Argentina.

Although obesity and non-communicable disease (NCD) prevention efforts to-date have focused mainly on individual level factors, the social and physical environments in which people live are now widely recognized as important social determinants of health. Obesogenic environments promote higher dietary energy intakes and sedentary behaviors, thus contributing to the obesity/NCD burden. To develop quality indicators (QIs) for measuring food and physical activity (PA)-built environments in municipalities. A literature review was conducted. Based on the best practices identified from this review, a draft set of candidate QI was retrieved. The initial 67 QIs were then evaluated by a modified Delphi panel of multidisciplinary health professionals (n = 40) to determine their relevance, validity, and feasibility in 3 rounds of voting and threaded discussion using a modified RAND/University of California, Los Angeles Appropriateness Methodology. Response rate for the panel was 89.4%. All final 42 QIs were rated as highly relevant, valid, and feasible (median rating ≥ 7 on a 1-9 scale), with no significant disagreement. The final QI set addresses for the PA domain: (i) promotion of PA; and (ii) improvements in the environment to strengthen the practice of PA; and for Food environment domain: (i) promotion of healthy eating; (ii) access to healthy foods; and (iii) promotion of responsible advertising. We generated a set of indicators to evaluate the PA and food built environment, which can be adapted for use in Latin American and other low- and middle-income countries.

The built environment has a considerable effect on health indicators such as physical activity, eating behavior, and community. There is considerable research evidence demonstrating a direct relationship between our built environments and our health. In Argentina, the Healthy Municipalities and Communities Program focuses in health promotion interventions. It was developed to seek collaboration among community members, local government authorities and other stakeholders in order to improve quality of life. However, up to date, there has not been a homogenous measure to evaluate how well a particular locality or a whole municipality supports the health and wellbeing its residents. The proposed study aims to develop a set of local valid and common measures in order to evaluate what is happening within a particular municipality. A designated group of local experts will select a set of final measures trough out an iterative multistage process in order to combine opinion into group consensus. We will ask the panel to rate, discuss and re-rate the proposed measures (based on the existing evidence). This will study provide an evaluative tool to inform policy making and program implementation, and to guide programs and initiatives aimed at combating obesogenic environments in municipalities and communities.

Association between drinking patterns and cardiovascular risk: a population-based study in the Southern Cone of Latin America.

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.

A review of assessment indicators used by Healthy Municipalities and Communities Program in Latin America and the Caribbean region.

The Healthy Municipalities and Communities Strategy (HMCS) was developed by the Pan American Health Organization in 1990. Evaluation and monitoring are fundamental components of health promotion policies. The aim of this study is to explore the indicators used in Latin America and the Caribbean (LAC) countries to assess the performance of HMCS. We searched MEDLINE, EMBASE, LILACS, BVSDE and Google Advanced Search for documents published between January 2000 and April 2016. We included only documents with assessment indicators of the strategy. All articles were independently assessed for eligibility by pairs of reviewers. We classified the indicators with a supporting framework proposed by O'Neill and Simard (Choosing indicators to evaluate Healthy Cities projects: a political task? Health Promot Int 2006, 21, 145-152.). Local level indicators figured far more prominently among countries and were distributed both in projects and specific activities. Regarding the evolution of the HMCS, indicators were reported in the five levels of analysis (local projects and activities, provincial, national and international networks). Empowerment was represented through the presence of active community organizations and different methods of community participation (forums, open hearing and participation maps). Public policies (such as for tobacco cessation) and bylaws adherence and changes in school's curricula regarding healthy eating were frequently mentioned. However, this review demonstrated that impact indicators related to lifestyle changes or built environment are not clearly defined and there is a lack of indicators to measure progress in achieving change in long-term outcomes in LAC. We highlight the importance of designing validated indicators for measuring the impact of health promotion policies in partnership with each country involved.

Epidemiology and risk factors of asthma-chronic obstructive pulmonary disease overlap in low- and middle-income countries.

BACKGROUND: Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) represents the confluence of bronchial airway hyperreactivity and chronic airflow limitation and has been described as leading to worse lung function and quality of life than found with either singular disease process. OBJECTIVE: We aimed to describe the prevalence and risk factors for ACO among adults across 6 low- and middle-income countries (LMICs). METHODS: We compiled cross-sectional data for 11,923 participants aged 35 to 92 years from 4 population-based studies in 12 settings. We defined COPD as postbronchodilator FEV1/forced vital capacity ratio below the lower limit of normal, asthma as wheeze or medication use in 12 months or self-reported physician diagnosis, and ACO as having both. RESULTS: The prevalence of ACO was 3.8% (0% in rural Puno, Peru, to 7.8% in Matlab, Bangladesh). The odds of having ACO were higher with household exposure to biomass fuel smoke (odds ratio [OR], 1.48; 95% CI, 0.98-2.23), smoking tobacco (OR, 1.28 per 10 pack-years; 95% CI, 1.22-1.34), and having primary or less education (OR, 1.35; 95% CI, 1.07-1.70) as compared to nonobstructed nonasthma individuals. ACO was associated with severe obstruction (FEV1 %, <50; 31.6% of ACO vs 10.9% of COPD alone) and severe spirometric deficits compared with participants with asthma (-1.61 z scores FEV1; 95% CI, -1.48 to -1.75) or COPD alone (-0.94 z scores; 95% CI, -0.78 to -1.10). CONCLUSIONS: ACO may be as prevalent and more severe in LMICs than has been reported in high-income settings. Exposure to biomass fuel smoke may be an overlooked risk factor, and we favor diagnostic criteria for ACO that include environmental exposures common to LMICs.

Validation and calibration of the patient health questionnaire (PHQ-9) in Argentina.

BACKGROUND: The Patient Health Questionnaire-9 (PHQ-9) is a brief tool to assess the presence and severity of depressive symptoms. This study aimed to validate and calibrate the PHQ-9 to determine appropriate cut-off points for different degrees of severity of depression in Argentina. METHODS: We conducted a cross-sectional study on an intentional sample of adult ambulatory care patients with different degrees of severity of depression. All patients who completed the PHQ-9 were further interviewed by a trained clinician with the Mini International Neuropsychiatric Interview (MINI) and the Beck Depression Inventory-II (BDI-II). Reliability and validity tests, including receiver operating curve analysis, were performed. RESULTS: One hundred sixty-nine patients were recruited with a mean age of 47.4 years (SD = 14.8), of whom 102 were females (60.4%). The local PHQ-9 had high internal consistency (Cronbach's alpha = 0.87) and satisfactory convergent validity with the BDI-II scale [Pearson's correlation = 0.88 (p < 0.01)]. For the diagnosis of Major Depressive Episode (MDE) according to the MINI, a PHQ-9 ≥ 8 was the optimal cut-off point found (sensitivity 88.2%, specificity 86.6%, PPV 90.91%). The local version of PHQ-9 showed good ability to discriminate among depression severity categories according to the BDI-II scale. The best cut off points were 6-8 for mild cases, 9-14 for moderate and 15 or more for severe depressive symptoms respectively. CONCLUSIONS: The Argentine version of the PHQ-9 questionnaire has shown acceptable validity and reliability for both screening and severity assessment of depressive symptoms.

Lack of an Association Between Household Air Pollution Exposure and Previous Pulmonary Tuberculosis.

CONTEXT: Observational studies investigating household air pollution (HAP) exposure to biomass fuel smoke as a risk factor for pulmonary tuberculosis have reported inconsistent results. OBJECTIVE: To evaluate the association between HAP exposure and the prevalence of self-reported previous pulmonary tuberculosis. DESIGN: We analyzed pooled data including 12,592 individuals from five population-based studies conducted in Latin America, East Africa, and Southeast Asia from 2010 to 2015. We used multivariable logistic regression to model the association between HAP exposure and self-reported previous pulmonary tuberculosis adjusted for age, sex, tobacco smoking, body mass index, secondary education, site and country of residence. RESULTS: Mean age was 54.6 years (range of mean age across settings 43.8-59.6 years) and 48.6% were women (range of % women 38.3-54.5%). The proportion of participants reporting HAP exposure was 38.8% (range in % HAP exposure 0.48-99.4%). Prevalence of previous pulmonary tuberculosis was 2.7% (range of prevalence 0.6-6.9%). While participants with previous pulmonary tuberculosis had a lower pre-bronchodilator FEV1 (mean - 0.7 SDs, 95% CI - 0.92 to - 0.57), FVC (- 0.52 SDs, 95% CI - 0.69 to - 0.33) and FEV1/FVC (- 0.59 SDs, 95% CI - 0.76 to - 0.43) as compared to those who did not, we did not find an association between HAP exposure and previous pulmonary tuberculosis (adjusted odds ratio = 0.86; 95% CI 0.56-1.32). CONCLUSIONS: There was no association between HAP exposure and self-reported previous pulmonary tuberculosis in five population-based studies conducted worldwide.

Association between Household Air Pollution Exposure and Chronic Obstructive Pulmonary Disease Outcomes in 13 Low- and Middle-Income Country Settings.

RATIONALE: Forty percent of households worldwide burn biomass fuels for energy, which may be the most important contributor to household air pollution. OBJECTIVES: To examine the association between household air pollution exposure and chronic obstructive pulmonary disease (COPD) outcomes in 13 resource-poor settings. METHODS: We analyzed data from 12,396 adult participants living in 13 resource-poor, population-based settings. Household air pollution exposure was defined as using biomass materials as the primary fuel source in the home. We used multivariable regressions to assess the relationship between household air pollution exposure and COPD outcomes, evaluated for interactions, and conducted sensitivity analyses to test the robustness of our findings. MEASUREMENTS AND MAIN RESULTS: Average age was 54.9 years (44.2-59.6 yr across settings), 48.5% were women (38.3-54.5%), prevalence of household air pollution exposure was 38% (0.5-99.6%), and 8.8% (1.7-15.5%) had COPD. Participants with household air pollution exposure were 41% more likely to have COPD (adjusted odds ratio, 1.41; 95% confidence interval, 1.18-1.68) than those without the exposure, and 13.5% (6.4-20.6%) of COPD prevalence may be caused by household air pollution exposure, compared with 12.4% caused by cigarette smoking. The association between household air pollution exposure and COPD was stronger in women (1.70; 1.24-2.32) than in men (1.21; 0.92-1.58). CONCLUSIONS: Household air pollution exposure was associated with a higher prevalence of COPD, particularly among women, and it is likely a leading population-attributable risk factor for COPD in resource-poor settings.

Low Body Mass Index Is Associated with Higher Odds of COPD and Lower Lung Function in Low- and Middle-Income Countries.

The relationship of body mass index (BMI) with lung function and COPD has been previously described in several high-income settings. However, few studies have examined this relationship in resource-limited settings where being underweight is more common. We evaluated the association between BMI and lung function outcomes across 14 diverse low- and middle-income countries. We included data from 12,396 participants aged 35-95 years and used multivariable regressions to assess the relationship between BMI with either COPD and lung function while adjusting for known risk factors. An inflection point was observed at a BMI of 19.8 kg/m2. Participants with BMI < 19.8 kg/m2 had a 2.28 greater odds (95% CI 1.83-2.86) of having COPD and had a 0.21 (0.13-0.30) lower FEV1 and 0.34 (0.27-0.41) lower FEV1/FVC z-score compared to those with BMI ≥ 19.8 kg/m2. The association with lung function remained even after excluding participants with COPD. Individuals with lower BMI were more likely to have COPD and had lower lung function compared to those in higher BMI. The association with lung function remained positive even after excluding participants with COPD, suggesting that being underweight may also play a role in having worse lung function.

Cost-Effectiveness of a Comprehensive Approach for Hypertension Control in Low-Income Settings in Argentina: Trial-Based Analysis of the Hypertension Control Program in Argentina.

BACKGROUND: A recent cluster randomized trial evaluating a multicomponent intervention showed significant reductions in blood pressure in low-income hypertensive subjects in Argentina. OBJECTIVES: To assess the cost-effectiveness of this intervention. METHODS: A total of 1432 hypertensive participants were recruited from 18 primary health care centers. The intervention included home visits led by community health workers, physician education, and text messaging. Resource use and quality of life data using the three-level EuroQol five-dimensional questionnaire were prospectively collected. The study perspective was that of the public health care system, and the time horizon was 18 months. Intention-to-treat analysis was used to analyze cost and health outcomes (systolic blood pressure [SBP] change and quality-adjusted life-years [QALYs]). A 1 time gross domestic product per capita per QALY was used as the cost-effectiveness threshold (US $14,062). RESULTS: Baseline characteristics were similar in the two arms. QALYs significantly increased by 0.06 (95% confidence interval [CI] 0.04-0.09) in the intervention group, and SBP net difference favored the intervention group: 5.3 mm Hg (95% CI 0.27-10.34). Mean total costs per participant were higher in the intervention arm: US $304 in the intervention group and US $154 in the control group (adjusted difference of US $140.18; 95% CI US $75.41-US $204.94). The incremental cost-effectiveness ratio was $3299 per QALY (95% credible interval 1635-6099) and US $26 per mm Hg of SBP (95% credible interval 13-46). Subgroup analysis showed that the intervention was cost-effective in all prespecified subgroups (age, sex, cardiovascular risk, and body mass index). CONCLUSIONS: The multicomponent intervention was cost-effective for blood pressure control among low-income hypertensive patients.

Community-based cardiovascular health promotion in Argentina. A systematic review.

In Argentina, cardiovascular disease (CVD) accounts for 30% of deaths and more than 600 000 disability-adjusted life years. However, no reviews describing local studies on interventions to address CVD risk factors have been identified. The purpose of this study is to characterize those population-based interventions and public policies implemented in Argentina to reduce the burden of cardiovascular disease with an adequate evaluation of their impact on population health. We conducted a systematic review of studies that assessed interventions in health promotion and/or primary prevention conducted in adult populations of Argentina, addressing specific CVD factors, from 1999 to 2016. We searched major bibliographic databases, grey literature, ministries and secretariats of health, and academic national libraries. Key informants, non-governmental organizations, universities, hospitals and experts were also contacted. We applied specific inclusion criteria. We assessed the methodological quality of the studies and reported the effectiveness and impact of population interventions and policies, as well as process evaluations' characteristics. After removing duplicates we identified 1686 references from databases. After reviewing title and abstracts 18 studies were selected, five of them corresponded to evaluations of public policies-all addressing tobacco smoking. We presented a structured review of each experience. Most of the studies were deemed to entail moderate or high risk of bias. We summarized the findings and characteristics of these studies, including implementation strategies, process and impact evaluation. This is the first systematic review of interventions focused on primary prevention and health promotion to counter CVD and diabetes in Argentina.

[Health impact assessment of the Program Healthy Centers in the Autonomous City of Buenos Aires, ArgentinaAvaliação do impacto na saúde do Programa Estações Saudáveis na Cidade Autônoma de Buenos Aires, Argentina]. / Evaluación del impacto sanitario del Programa Estaciones Saludables en la Ciudad Autónoma de Buenos Aires, Argentina.

OBJECTIVE: To explore the motivations and expectations of the users of the Program for Healthy Centers in the Autonomous City of Buenos Aires and to evaluate its potential health impact. METHODS: In-depth interviews were conducted (n = 34) and a self-administered survey was sent to users of the program (n = 605). An epidemiological model was developed to estimate the impact of the program on cardiovascular events (CVE) and disability-adjusted life years (DALYs). RESULTS: The main motivating factors for using the healthy centers were geographic and economic accessibility (free services) and satisfaction with the care received. 14.4% (95% CI, 10.3-18.5%) of hypertensive users and 24.8% (95% CI, 17.6-32.0%) of diabetic users reported having learned of their altered values in the healthy center. More than half of the respondents reported some improvement in their knowledge about the benefits of physical activity and healthy eating; this was more frequent among those who were younger, of lower educational level, users of the public health system, users of a healthy center in the South zone and those who had a cardiometabolic risk factor (p<0.05). It was estimated that the healthy centers would prevent 12.5 cardiovascular and cerebrovascular events per year in the assisted population (4.75 events/100 000) and 47.75 DALYs due to these causes. CONCLUSIONS: The healthy centers are a favorable space for the implementation of health promotion and prevention actions, contributing to the detection of and facilitating the monitoring of risk factors, with a potential to prevent cardiovascular events and its consequences.

OBJETIVO: Explorar as motivações e expectativas dos usuários do Programa Estações Saudáveis na Cidade Autônoma de Buenos Aires e avaliar seu impacto potencial na saúde. MÉTODOS: Foram realizadas entrevistas em profundidade (n = 34) e uma pesquisa auto-administrada (n = 605) a usuários do programa. Um modelo epidemiológico foi desenvolvido para estimar o impacto do programa em eventos cardiovasculares e anos de vida ajustados por incapacidade (DALY). RESULTADOS: Os principais fatores motivadores para o uso do estações saudáveis foram a acessibilidade geográfica, econômica (serviços gratuitos) e a satisfação com o atendimento recebido. 14,4% (intervalo de confiança de 95% [IC95%] 10,3-18,5%) de usuários hipertensos e 24,8% (IC95% 17,6-32,0%) dos diabéticos relataram ter aprendido sobre seus valores alterados na estação saudável. Mais da metade dos entrevistados relataram alguma melhora no conhecimento sobre os benefícios da atividade física e da alimentação saudável, com maior freqüência entre os mais jovens, de menor escolaridade, usuários do sistema público de saúde, usuários de estações saudáveis na zona sul e aqueles que apresentaram algum fator de risco cardiometabólico (p<0,05). Estimou-se que, devido à existência de estações saudáveis, 12,5 eventos cardiovasculares e cerebrovasculares por ano seriam evitados na população atendida (4,75 eventos/100 000) e 47,75 DALY por essas causas. CONCLUSÕES: As estações saudáveis são um espaço propício para a implementação de ações de promoção e prevenção da saúde, contribuindo para a detecção e facilitação do monitoramento dos fatores de risco, com potencial para prevenir os eventos cardiovasculares e suas consequências.

Associations between dietary patterns and serum lipids, apo and C-reactive protein in an adult population: evidence from a multi-city cohort in South America.

Several previous epidemiological studies from developed countries have shown that an unhealthy dietary pattern affects plasma lipid levels and inflammation biomarkers. We assessed the cross-sectional associations between dietary patterns and cardiovascular risk factors among 961 adults from a multi-city cohort in South America. We conducted a principal component analysis to derive dietary patterns. As outcomes, we examined plasma levels of apo A-I, apo B, high-sensitivity C-reactive protein (hs-CRP), LDL-, HDL- and serum total cholesterol and TAG. The crude and adjusted changes in each outcome were estimated for quartiles of dietary patterns using multivariable linear regression models. The prudent pattern (PP) characterised by higher intake of fruits, vegetables, fish, seafood, whole cereal and low-fat dairy products was associated with reduced plasma concentrations of apo B (-8·5 mg/l), total cholesterol (-18·8 mg/dl) and LDL-cholesterol (-16·5 mg/dl) and hs-CRP (-1·6 mg/l) in men. In women also reduced plasma concentrations of apo B (-6·6 mg/l), total (-12·0 mg/dl) and LDL (-9·3 mg/dl). The 'Western-like' pattern characterised by higher intake of eggs, pastry and cakes, pizza, snacks, refined grains, red meat, vegetable oils and poultry was not significantly associated with any of the selected serum lipid or inflammatory biomarkers. The explained variances were 10·3 and 7·4 %, respectively. The PP was associated with better lipid profile, mainly lower atherogenic particles (apo B) and LDL-cholesterol and serum total cholesterol. This study provides possible evidence of a prudent diet in South American populations to help reduce the burden of CVD.
