    This report examines the challenges of conducting a multicenter, cross-sectional study of countries with diverse cultures, and shares the lessons learned. The Latin American Study of Nutrition and Health (ELANS) was used as a feasibility study involving the most populous cities of eight countries in Latin America (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela) in 2014-2015, about 40% of the population of the Americas. The target sample included 9 000 individuals, 15-65 years of age, and was stratified by geographic location (only urban areas), gender, age, and socioeconomic status.

    (2020) de Moraes Ferrari, Gerson Luis; Kovalskys, Irina; Fisberg, Mauro; Gomez, Georgina; Rigotti, Attilio; Cortes Sanabria, Lilia Yadira; Yepez Garcia, Martha Cecilia; Pareja Torres, Rossina Gabriella; Herrera-Cuenca, Marianella; Zimberg, Iona Zalcman; Guajardo, Viviana; Pratt, Michael; Scholes, Shaun; Goncalves, Priscila Bezerra; Sole, Dirceu
    Worldwide studies of physical activity and sedentary time have historically under-represented low- and middle-income countries due to the lack of surveillance data. The purpose of this paper is to describe the methods and procedures used for the assessment of physical activity and sedentary time in the Latin American Study of Nutrition and Health (Estudio Latinoamericano de NutriciOn y Salud; ELANS). ELANS is a multicentre, cross-sectional and surveillance study of a nationally representative sample from eight Latin American countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela. Two instruments were used to evaluate different domains and intensities of physical activity and sedentary time: self-reported data and a triaxial accelerometer (model GT3X+). ELANS will generate important self-reported and objective information for the Latin American populations, namely:
