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.

Riesgo común e indicadores de Enfermedades no transmisibles y salud bucal

Las enfermedades no transmisibles (ENT) comparten factores de riesgo para su desarrollo con las patologías bucales, estas pueden ser abordadas en forma conjunta desde el enfoque de riesgo común. El objetivo de este trabajo fue comparar como se definen los factores de riesgo y qué indicadores se usan para medir la salud bucal y enfermedades no transmisibles en seis trabajos epidemiológicos uruguayos seleccionados. Se sistematizaron los factores de riesgo relevados, la forma en que se recogieron los datos y las definiciones de riesgo para cada uno. Se constató que el objetivo de cada estudio fue diferente, existiendo discrepancia en las variables y en los indicadores escogidos, así como en su definición, operacionalización y forma de recolectar los datos. Sería importante contar con criterios unificados e información sistematizada e integrada para tomar decisiones sanitarias con respecto al abordaje individual y colectivo de las ENT, así como también incluir la salud bucal a la hora de abordar las ENT.

As doenças não transmissíveis (DNTs) compartilham fatores de risco para sua ocorrência com as patologias bucais, que podem ser tratadas em conjunto por meio da abordagem de risco comum. O objetivo desse trabalho foi comparar como os fatores de risco são definidos e quais indicadores são usados para medir a saúde bucal e as doenças não transmissíveis em seis estudos epidemiológicos selecionados no Uruguai. Os fatores de risco pesquisados, a forma como os dados foram coletados e as definições de risco para cada um deles foram sistematizados. Verificou-se que o objetivo de cada estudo era diferente, com discrepâncias nas variáveis e nos indicadores escolhidos, bem como em sua definição, operacionalização e na forma como os dados foram coletados. Seria importante ter critérios unificados e informações sistematizadas e integradas para tomar decisões de saúde em relação à abordagem individual e coletiva das DNTs, bem como incluir a saúde bucal na abordagem das DNTs.

Non-communicable diseases (NCDs) share risk factors for their development with oral pathologies and can be addressed jointly through the common risk approach. The aim of this work was to compare the definitions and indicators of oral health risk factors and NCDs in six selected Uruguayan epidemiological studies. The risk factors surveyed, the way in which data were collected and the risk definitions for each one were systematized. It was found that the objective of each study was different, with discrepancies in the variables and indicators chosen as well as in their definition, operationalization and way of collecting data. It would be important to have unified criteria and systematized and integrated information to make health decisions regarding the individual and collective approach to NCDs, as well as to include oral health when addressing NCDs.

Suicidal ideation is associated with cardiovascular disease in a large, urban cohort of adults in the Southern Cone of Latin America.

INTRODUCTION: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

External Validation of Cardiovascular Risk Scores in the Southern Cone of Latin America: Which Predicts Better? / Validación externa de ecuaciones de riesgo cardiovascular en el Cono Sur de Latinoamérica: ¿cuál predice mejor?

ABSTRACT: Background: Inaccurate estimates of demographic cardiovascular risk may lead to an inadequate management of preventive medical interventions such as the use of statins. Objectives: The aim of this study was to evaluate the external validity of cardiovascular risk equations in the general population of the Southern Cone of Latin America. Methods: Equations including variables evaluated in the CESCAS cohort study and that estimate overall cardiovascular mortality (CUORE, Framingham, Globorisk and Pooled Cohort Studies) were assessed. For each equation, an independent analysis was per-formed taking into account the cardiovascular events originally considered. Discrimination of each equation was evaluated through C-statistic and Harrell's C-index. To assess calibration, a graph was built for each equation with the proportion of observed events vs. the proportion of estimated events by risk quintiles and the β slope of the resulting linear regression was calculated. Sensitivity and specificity were determined for the detection of people at high cardiovascular risk. results: The median follow-up time of the cohort at the time of the analysis was 2.2 years, with an interquartile range of 1.9 to 2.8 years. Sixty cardiovascular events were incorporated into the analysis. All C-statistic and Harrell's-C index values were greater than 0.7. The value of the β slope farthest from 1 was that of the Pooled Cohort Studies score. Conclusions: Although the external validation parameters evaluated were similar, CUORE, Globorisk and the Framingham equa-tions showed the best global performance for cardiovascular risk estimation in our population.

RESUMEN: introducción: La estimación inexacta del riesgo cardiovascular poblacional puede llevar a un manejo inadecuado de las intervenciones médicas preventivas, como, por ejemplo, el uso de estatinas. Objetivo: Evaluar la validez externa de ecuaciones de predicción de riesgo cardiovascular en población general del Cono Sur de Latinoamérica. Material y métodos: Se evaluaron ecuaciones que incluyen variables evaluadas en el estudio CESCAS y que predicen tanto morbilidad como mortalidad cardiovascular global (CUORE, Framingham, Globorisk y Pooled Cohort Studies Equations). Para cada ecuación se realizó un análisis independiente en el que se tuvieron en cuenta los eventos cardiovasculares relevados. Se evaluó la discriminación de cada ecuación a través del cálculo del estadístico-C y el índice Harrell C. Para evaluar la calibración se graficó la proporción de riesgos observados vs. estimados por quintilos de riesgo para cada ecuación y se calculó la pendiente β de regresión lineal para las estimaciones. Se calculó sensibilidad y especificidad para la detección de personas con elevado riesgo cardiovascular. resultados: La mediana del tiempo de seguimiento de la cohorte al momento del análisis es de 2,2 años, con un rango intercuartilo de 1,9 a 2,8 años. Se incorporaron a los análisis 60 eventos cardiovasculares. Todos los valores de estadístico-C y del índice de Harrell fueron superiores a 0,7. El valor de la pendiente β más alejado de 1 fue el de Pooled Cohort Studies Euations. Conclusiones: Si bien los parámetros de validación externa evaluados fueron similares, CUORE, Globorisk y el índice de Framing-ham fueron las ecuaciones con mejores indicadores globales de predicción de riesgo cardiovascular.
