Item Differences in the association of cardiovascular risk factors with education: a comparison of Costa Rica (CRELES) and the USA (NHANES)(J Epidemiol Community Health 2010: 64, 2009) Rehkopf, David H.; Dow, William H.; Rosero Bixby, LuisBackground Despite different levels of economic development, Costa Rica and the USA have similar mortalities among adults. However, in the USA there are substantial differences in mortality by educational attainment, and in Costa Rica there are only minor differences. This contrast motivates an examination of behavioural and biological correlates underlying this difference. Methods The authors used data on adults aged 60 and above from the Costa Rican Longevity and Healthy Ageing Study (CRELES) (n¼2827) and from the US National Health and Nutrition Examination Survey (NHANES) (n¼5607) to analyse the cross-sectional association between educational level and the following risk factors for cardiovascular disease (CVD): ever smoked, current smoker, sedentary, high saturated fat, high carbohydrates, high calorie diet, obesity, severe obesity, large waist circumference, HDL cholesterol, LDL cholesterol, triglycerides, hemoglobin A1c, fasting glucose, C-reactive protein, systolic blood pressure and BMI. Results There were significantly fewer hazardous levels of risk biomarkers at higher levels of education for more than half (10 out of 17) of the risk factors in the USA, but for less than a third of the outcomes in Costa Rica (five out of 17). Conclusions These results are consistent with the context-specific nature of educational differences in risk factors for CVD and with a non-uniform nature of association of CVD risk factors with education within countries. Our results also demonstrate that social equity in mortality is achieved without uniform equity in all risk factors.Item 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.
