Ítem Derivation, internal validation, and recalibration of a cardiovascular risk score for Latin America and the Caribbean (Globorisk-LAC): A pooled analysis of cohort studies(The Lancet Regional Health - Americas, 9, 2022) Stern, Dalia; Hambleton, Ian R.; Lotufo, Paulo Andrade; Di Cesare, Mariachiara; Hennis, Anselm; Ferreccio, Catterina; Irazola, Vilma; Perel, Pablo; Gregg, Edward W.; Aguilar Salinas, Carlos Alberto; Álvarez Vaz, Ramón; Amadio, Marselle Bevilacqua; Baccino, Cecilia; Bambs S., Claudia; Bastos, João Luiz Dornelles; Beckles, Gloria; Bernabé Ortiz, Antonio; Bernardo, Carla; Bloch, Katia Vergetti; Blümel, Juan Enrique; Boggia, José G.; Borges, Pollyana Kássia de Oliveira; Bravo, Miguel; Brenes Camacho, Gilbert; Carbajal, Horacio A.; Casas Vásquez, Paola; Castillo Rascón, María Susana; Ceballos, Blanca H.; Colpani, Verônica; Cooper, Jackie A.; Cortés, Sandra; Cortés Valencia, Adrián; de Sá Cunha, Roberto; d'Orsi, Eleonora; Dow, William H.; Espeche, Walter G.; Fuchs, Flavio Danni; Pereira Costa Fuchs, Sandra Cristina; Godoy Agostinho Gimeno, Suely; Gómez Velasco, Donaji Verónica; González Chica, David Alejandro; González Villalpando, Clicerio; González Villalpando, María Elena; Grazioli, Gonzalo; Guerra, Ricardo Oliveira; Gutierrez, Laura E.; Herkenhoff Vieira, Fernando Luiz; Horimoto, Andrea Roseli Vancan Russo; Huidobro Muñoz, Laura Andrea; Koch, Elard S.; Lajous Loaeza, Martin; Furtado de Lima e Costa, Maria Fernanda; López Ridaura, Ruy; Campos Cavalcanti Maciel, Álvaro; Maestre, Gladys Elena; Manrique Espinoza, Betty Soledad; Marques, Larissa Pruner; Melgarejo Arias, Jesus David; Mena Camaré, Luis Javier; Mill, Jose Gerardo; Moreira, Leila Beltrami; Muñoz Velandia, Oscar Mauricio; Ono, Lariane Mortean; Oppermann, Karen; Ortiz Saavedra, Pedro José; de Paiva, Karina Mary; Viana Peixoto, Sérgio William; da Costa Pereira, Alexandre; Peres, Karen G.; de Anselmo Peres, Marco Aurelio; Ramírez Palacios, Paula; Rech, Cassiano Ricardo; Rivera Paredez, Berenice; Rodríguez Guerrero, Nohora Inés; Rojas Martínez, Maria Rosalba; Rosero Bixby, Luis; Rubinstein, Adolfo; Ruiz Morales, Álvaro de Jesus; Salazar, Martin R.; Salinas Rodríguez, Aarón; Nájera Salmerón, Jorge Alberto; Sánchez, Ramón Augusto; de Souza e Silva, Nelson Albuquerque; Nogueira da Silva, Thiago Luiz; Smeeth, Liam; Spritzer, Poli Mara; Tartaglione, Fiorella; Tartaglione, Jorge; Tello Rodríguez, Tania; Velázquez Cruz, Rafael; Cohorts Consortium of Latin America and the Caribbean (CC-LAC); Carrillo Larco, Rodrigo Martín; Miranda Montero, Juan J.; Ezzati, Majid; Danaei, GoodarzBackground: Risk stratification is a cornerstone of cardiovascular disease (CVD) prevention and a main strategy proposed to achieve global goals of reducing premature CVD deaths. There are no cardiovascular risk scores based on data from Latin America and the Caribbean (LAC) and it is unknown how well risk scores based on European and North American cohorts represent true risk among LAC populations. Methods: We developed a CVD (including coronary heart disease and stroke) risk score for fatal/non-fatal events using pooled data from 9 prospective cohorts with 21,378 participants and 1,202 events. We developed laboratory based (systolic blood pressure, total cholesterol, diabetes, and smoking), and office-based (body mass index replaced total cholesterol and diabetes) models. We used Cox proportional hazards and held back a subset of participants to internally validate our models by estimating Harrell’s C-statistic and calibration slopes. Findings: The C-statistic for the laboratory-based model was 72% (70−74%), the calibration slope was 0.994 (0.934−1.055) among men and 0.852 (0.761−0.942) among women; for the office-based model the C-statistic was 71% (69−72%) and the calibration slope was 1.028 (0.980−1.076) among men and 0.811 (0.663−0.958) among women. In the pooled sample, using a 20% risk threshold, the laboratory-based model had sensitivity of 21.9% and specificity of 94.2%. Lowering the threshold to 10% increased sensitivity to 52.3% and reduced specificity to 78.7%. Interpretation: The cardiovascular risk score herein developed had adequate discrimination and calibration. The Globorisk-LAC would be more appropriate for LAC than the current global or regional risk scores. This work provides a tool to strengthen risk-based cardiovascular prevention in LAC.Ítem Major cardiovascular risk factors in Latin America: a comparison with the United States. The Latin American consortium of studies in obesity (LASO)(PLOS ONE, vol.8(1), 2013) Miranda Montero, Jaime J.; Herrera Galindo, Víctor Mauricio; Chirinos Medina, Julio A.; Gómez Gutiérrez, Luis Fernando; Perel, Pablo; Pichardo Estevez, Rafael; González Medina, Angel; Sánchez Abanro, José Ramón; Ferreccio, Catterina; Aguilera Sanhueza, Ximena; Silva, Eglé; Oróstegui, Myriam; Medina Lezama, Josefina; Pérez, Cynthia M.; Suárez, Erick; Ortiz Martínez, Ana Patricia; Rosero Bixby, Luis; Schapochnik, Noberto; Ortiz, Zulma; Ferrante, Daniel; Casas, Juan P.; Bautista Lorenzo, Leonelo EnriqueLimited knowledge on the prevalence and distribution of risk factors impairs the planning and implementation of cardiovascular prevention programs in the Latin American and Caribbean (LAC) region. For the last two decades cardiovascular diseases have been the main cause of death in Latin America and the Caribbean (LAC). [1] Cardiovascular mortality rates continue to increase in most LAC countries, and in those countries where rates have declined the blunting of the trend has been considerably lower than in the United Sates (US). [2]. Data on the distribution of cardiovascular risk factors in LAC region are limited, and the few studies available show significant variation in the levels of prevalence. For instance, the CARMELA study, [3] conducted in seven major urban cities from LAC, reprted markedly different hypertension levels. For instance, hypertension prevalence in Santiago (Chile), Buenos Aires (Argentina), and Barquisimeto (Venezuela), ranged from 24% to 29%, whereas in Quito (Ecuador), Bogotá (Colombia), Mexico City (Mexico), and Lima (Peru) varied from 9% to 13%. Yet, diabetes prevalence in these cities was similar to world’s estimates, around 7%. [3] Differences in rural-urban residence, socioeconomic development, and internal migration patterns could partly explain the contrasting profiles of cardiovascular risk factors, but knowledge on this regard is also very limited. This scarcity of data on the distribution of risk factors and, in turn, on their impact on incidence and mortality hampers efforts to curtail the growing epidemic of cardiovascular disease in LAC. In fact, national and regional health policies have been customarily based on estimates of the burden of risk factors and disease that rely heavily on demographic profiles. [4]. Here we reprt the distribution of cardiovascular risk factors using data from population-based studies from eight LAC countries. We also compare the distribution of cardiovascular risk factors in LAC and the US, as a way to illustrate the current stage of LAC in the process of the epidemiological transition. Insight into the specific differences in the distribution of risk factors in the LAC and US populations is important to foresee future trends in cardiovascular morbidity and mortality in the region.Ítem The Latin American Consortium of Studies in Obesity (LASO)(Obesity Reviews, vol.10(3), 2009) Bautista Lorenzo, Leonelo Enrique; Casas, Juan P.; Herrera Galindo, Víctor Mauricio; Miranda Montero, Jaime J.; Perel, Pablo; Pichardo Estevez, Rafael; González, Angel; Sánchez, José R.; Ferreccio, Catterina; Aguilera Sanhueza, Ximena; Silva, Eglé; Oróstegui, Myriam; Gómez Gutiérrez, Luis Fernando; Chirinos Medina, Julio A.; Medina Lezama, Josefina; Pérez, Cynthia M.; Suárez, Erick; Ortiz Martínez, Ana Patricia; Rosero Bixby, Luis; Schapochnik, Noberto; Ortiz, Zulma; Ferrante, DanielCurrent, high-quality data are needed to evaluate the health impact of the epidemic of obesity in Latin America. The Latin American Consortium of Studies of Obesity (LASO) has been established, with the objectives of (i) Accurately estimating the prevalence of obesity and its distribution by sociodemographic characteristics; (ii) Identifying ethnic, socioeconomic and behavioural determinants of obesity; (iii) Estimating the association between various anthropometric indicators or obesity and major cardiovascular risk factors and (iv) Quantifying the validity of standard definitions of the various indexes of obesity in Latin American population. To achieve these objectives, LASO makes use of individual data from existing studies. To date, the LASO consortium includes data from 11 studies from eight countries (Argentina, Chile, Colombia, Costa Rica, Dominican Republic, Peru, Puerto Rico and Venezuela), including a total of 32 462 subjects. This article describes the overall organization of LASO, the individual studies involved and the overall strategy for data analysis. LASO will foster the development of collaborative obesity research among Latin American investigators. More important, results from LASO will be instrumental to inform health policies aiming to curtail the epidemic of obesity in the region.
