    (2021) Ferrari, Gerson; Werneck, Andre O.; Silva, Danilo R.; Kovalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Cortes, Lilia Yadira; Garcia, Martha Yepez; Liria, Maria; Herrera-Cuenca, Marianella; Zimberg, Iona Zalcman; Guajardo, Viviana; Pratt, Michael; Cristi-Montero, Carlos; Marques, Adilson; Peralta, Miguel; Bolados, Cristian Cofre; Leme, Ana Carolina B.; Rollo, Scott; Fisberg, Mauro
    The purpose of this study was to analyze the agreement between self-reported and device-based sedentary time among eight countries in Latin America. As part of the Latin American Study of Nutrition and Health (ELANS), data were collected from 2524 participants (18-65 years) across eight countries. Participants reported time spent sedentary in different activities (computer use at home, videogame use, reading, sitting down to chat with friends/relatives or listening to music, speaking on the phone, watching TV, and riding in a car). Overall sitting time was assessed using a single item from the International Physical Activity Questionnaire (IPAQ). Device-based sedentary time was assessed using Actigraph GT3X accelerometers. Self-reported overall sitting time (227.1 min/day) produced the lowest values of the three assessment methods, followed by self-reported sum of different types of sedentary behavior (364.1 min/day) and device-based sedentary time (568.6 min/day). Overall, correlation coefficients and ICC varied from weak to moderate (rho: 0.25-0.39; ICC: 0.21:0.39) between self-reported sum of different types of sedentary behavior, self-reported overall sitting time, and device-based sedentary time. The Bland-Altman plots indicated low to moderate agreement between self-reported overall sitting time and device-based sedentary time by sex. Self-report measures underestimate sedentary behavior and overall sitting time when compared with device-based measures. The weak and moderate level of agreement between methods indicates that caution is required when comparing associations between different self-report and device-based measures of sedentary behavior with health outcomes.

    (2021) Herrera-Cuenca, Marianella; Kovalskys, Irina; Gerardi, Alejandro; Hernandez, Pablo; Sifontes, Yaritza; Gomez, Georgina; Yepez Garcia, Martha Cecilia; Mendez-Perez, Betty; Landaeta-Jimenez, Maritza; Pareja, Rossina; Cortes, Lilia Yadira; Rigotti, Attilio; Fisberg, Mauro; Zimberg, Iona Zalcman
    Background: Latin America has experienced changes in lifestyle since 1960.Aim: The aim was to determine the prevalence of obesity and stunting among eight countries of Latin American and to identify the determinant risk factors for obesity.Subjects and Methods: Data were obtained from 9,218 participants of the Latin American Study of Nutrition and Health (ELANS), a multicenter cross-sectional study of the representative samples in eight Latin American countries. All the participants completed a standard protocol to investigate the nutrient intake and anthropometric variables (weight, height, and circumferences) analyzed by country, gender, age, and socioeconomic status.Results: The prevalence of obesity was higher in Costa Rica and Venezuela (29%) and lower in Colombia (16%), stunting was reported higher in Peru (47%) and lower in Argentina (17%), and waist and neck circumferences showed the higher values in Costa Rica (43%) and Chile (52%) and lower values in Colombia (23 and 26%).Conclusion: This study indicates an increasing trend toward overweight and obesity that are associated with lower socioeconomic status, being a woman, and concurs with inadequate intakes of calcium, which may be related to poor quality diet and in the long term could constitute risk factors for the chronic diseases and a health burden to the region.

    Methodological design for the assessment of physical activity and sedentary time in eight Latin American countries - The ELANS study
    (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:

    Socio-demographic patterning of objectively measured physical activity and sedentary behaviours in eight Latin American countries: Findings from the ELANS study
    (2020) Ferrari, Gerson Luis de Moraes; Kovalskys, Irina; Fisberg, Mauro; Gomez, Georgina; Rigotti, Attilio; Sanabria, Lilia Yadira Cortes; Garcia, Martha Cecilia Yepez; Torres, Rossina Gabriella Pareja; Herrera-Cuenca, Marianella; Zimberg, Iona Zalcman; Guajardo, Viviana; Pratt, Michael; Cristi-Montero, Carlos; Rodriguez-Rodriguez, Fernando; Scholes, Shaun; Celis-Morales, Carlos A.; Chaput, Jean-Philippe; Sole, Dirceu
    Physical activity (PA) and sedentary behaviours (SB) are two independent risk factors for non-communicable diseases. However, there is a lack of objectively measured information on PA and SB in low- and middle-income countries. The aim of this study was to use objective data to characterise socio-demographic patterns of PA and SB in eight Latin American countries. 2732 participants (aged 15-65 years) from the Latin American Study of Nutrition and Health (ELANS) were included. PA and SB data were collected using accelerometers. Overall and country-specific average levels of time spent in PA and SB were compared by sex, age, socioeconomic and education level. Overall, the mean time spent in SB was 571.6 min/day, ranging from 553.8 min/day in Chile to 596.7 min/day in Peru. Average levels of light, moderate-to-vigorous physical activity (MVPA) and total PA were 311.1 min/day (95% CI: 307.7; 314.5), 34.9 min/day (95% CI: 34.0; 35.9) and 7531.2 MET-min/week (95% CI: 7450.4; 7611.9), respectively. MVPA and total PA were higher in men than women. The prevalence of physical inactivity was 40.6%, ranging from 26.9% (Chile) to 47% (Costa Rica and Venezuela). Women were more physically inactive than men (47.7% versus 33.0%). SB levels were highest among those with higher education; PA graded positively with socioeconomic level. Our findings can inform the planning of health policies and programmes designed to reduce levels of physical inactivity, as well as inform the local and cultural adaptation of these policies and programmes for implementation in Latin America. Highlights Worldwide studies of physical activity (PA) and sedentary behaviours (SB) have historically under-represented Latin American countries due to the lack of surveillance data. Across eight Latin American countries, the ELANS study collected data on PA and SB using an objective method (accelerometers) which we have analysed to quantify and characterise socio-demographic patterns. Over four-in-ten participants were physically inactive (40.6%); with a gender gap (47.7% women; 33.0% men); and striking differences between countries (47% Costa Rica and Venezuela; 26.9% Chile). In all countries, levels of moderate-to-vigorous physical activity (MVPA) were lowest, and levels of SB were highest, among participants in the higher education groups. Our findings on the unequal distribution of PA and SB increases the evidence base and can help to inform future intervention strategies in Latin America.
