    (2022) Ferrari, Gerson; Herrera-Cuenca, Marianella; Zalcman Zimberg, Iona; Guajardo, Viviana; Gomez, Georgina; Quesada, Dayana; Rigotti, Attilio; Yadira Cortes, Lilia; Yepez Garcia, Martha; Pareja, Rossina G.; Peralta, Miguel; Marques, Adilson; Leme, Ana Carolina B.; Kovalskys, Irina; Rollo, Scott; Fisberg, Mauro
    The purpose of this study was to examine the associations between self-reported and device-based measures of sedentary behavior (SB) with obesity markers in adults from Latin American countries. Sitting time and total time spent in different SBs were self-reported using two different questionnaires. Accelerometers were used to assess total sedentary time. Body mass index, waist, and neck circumferences were assessed. The highest self-reported sitting time was in Argentina, the highest total time spent in different SBs was in Brazil and Costa Rica, and the highest device-based sedentary time was observed in Peru. Neither self-reported sitting time, total time spent in different SBs or device-based sedentary time were associated with body mass index. Device-based sedentary time was positively associated with waist circumference and self-reported sitting time was positively associated with neck circumference. Caution is warranted when comparing the associations of self-reported and device-based assessments of SB with anthropometric variables.

    Meeting 24-h movement guidelines and markers of adiposity in adults from eight Latin America countries: the ELANS study
    (2022) Ferrari, Gerson; Cristi-Montero, Carlos; Drenowatz, Clemens; Kovalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Cortes, Lilia Yadira; Yepez Garcia, Martha; Liria-Dominguez, Maria Reyna; Herrera-Cuenca, Marianella; Peralta, Miguel; Marques, Adilson; Marconcin, Priscila; da Costa, Roberto Fernandes; Leme, Ana Carolina B.; Farias-Valenzuela, Claudio; Ferrero-Hernandez, Paloma; Fisberg, Mauro
    This study aimed to compare compliance with 24-h movement guidelines across countries and examine the associations with markers of adiposity in adults from eight Latin American countries. The sample consisted of 2338 adults aged 18-65 years. Moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) data were objectively measured using accelerometers. Sleep duration was self-reported using a daily log. Body mass index and waist circumference were assessed as markers of adiposity. Meeting the 24-h movement guidelines was defined as >= 150 min/week of MVPA; <= 8 h/day of SB; and between 7 and 9 h/day of sleep. The number of guidelines being met was 0.90 (95% CI 0.86, 0.93) with higher value in men than women. We found differences between countries. Meeting two and three movement guidelines was associated with overweight/obesity (OR: 0.75, 95% CI 0.58, 0.97 and OR: 0.69, 95% CI 0.51, 0.85, respectively) and high waist circumference (OR: 0.74, 95% CI 0.56, 0.97 and OR: 0.77, 95% CI 0.62, 0.96). Meeting MVPA and SB recommendations were related to reduced adiposity markers but only in men. Future research is needed to gain insights into the directionality of the associations between 24-h movement guidelines compliance and markers of adiposity but also the mechanisms underlying explaining differences between men and women.

    Perceived urban environment attributes and obesity indices in adults: an 8-Nation study from Latin America
    (2022) Ferrari, Gerson; Alberico, Claudia; Marques, Adilson; Kovalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Yadira Cortes, Lilia; Yepez Garcia, Martha; Pareja, Rossina G.; Herrera-Cuenca, Marianella; Drenowatz, Clemens; Leme, Ana Carolina B.; Cristi-Montero, Carlos; Fernandes da Costa, Roberto; Farias-Valenzuela, Claudio; Fisberg, Mauro
    This study examines the associations between perceived urban environment attributes and obesity indices by country using data from an eight-nation study from Latin America. The data were collected from 8185 adults. The Neighbourhood Environment Walkability-abbreviated scale was used to assess perceived urban environment attributes. Obesity indices considered were body mass index, waist circumference, neck circumference, a body shape index and waist-to-height ratio. The perception of a more and better land use mix-diversity (beta - 0.44; 95% CI - 0.59, - 0.28), traffic safety (- 0.39; - 0.66, - 0.12), and safety from crime (- 0.36; - 0.57, - 0.15) was associated with lower body mass index across the entire sample. Land use mix-diversity (- 1.21; - 1.60, - 0.82), street connectivity (- 0.26; - 0.37, - 0.15), and traffic safety (- 0.79; - 1.47, - 0.12) were negatively associated with waist circumference. Land use mix-diversity (- 0.11; - 0.20, - 0.03), land use mix-access (- 0.23; - 0.34, 0.12), walking/cycling facilities (- 0.22; - 0.37, - 0.08), and safety from crime (- 0.27; - 0.42, - 0.12) were negatively associated with neck circumference. No associations between perceived urban environment attributes and a body shape index were found. Land use mix-diversity (- 0.01; - 0.02, - 0.01), aesthetics (- 0.02; - 0.03, - 0.01), and safety from crime (- 0.02; - 0.04, - 0.01) were associated with waist-to-height ratio. Environmental interventions involving urban environment attributes are associated with obesity indices and, therefore, may help decrease the prevalence of overweight and obesity.

    Total and whole grain intake in Latin America: findings from the multicenter cross-sectional Latin American Study of Health and Nutrition (ELANS)
    (2022) Fisberg, Regina Mara; Fontanelli, Mariane Mello; Kowalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Yadira Cortes, Lilia; Yepez Garcia, Martha; Pareja, Rossina G.; Herrera-Cuenca, Marianella; Fisberg, Mauro
    Purpose Understanding whole-grain intake and its associated factors is essential to tackle the double burden of malnutrition faced by Latin American countries. This study aimed to characterize total and whole grain intake in Latin American countries and to investigate foods contributing to these intake in the region. Methods Data were obtained from the multicenter cross-sectional survey Latin American Study of Nutrition and Health (ELANS), including 9128 participants residing in urban areas of eight Latin American countries. Data collection was performed via two household visits using a standardized questionnaire and two 24 h dietary recalls. Usual dietary intake of total grain foods and foods containing whole grains was estimated. The association between the intake of grain food groups and sociodemographic variables was investigated using multiple linear regression models with random intercepts. Results Mean intake of total grain foods and foods containing whole grains was 318.6 g/d and 14.7 g/d, respectively. Total grain foods were less consumed by participants at older ages (-9.8 g/d), and females (-9.9 g/d), and more consumed by those in the lowest socioeconomic category (24.8 g/d). Foods containing whole grains were more consumed by participants at older ages (3.3 g/d), and females (4.0 g/d), while those in the lowest socioeconomic category consumed 2.9 g/d less. Major contributors to energy provided from foods containing whole grains were oatmeal, masa harina, whole-wheat bread, corn chips, and wheat crackers. Conclusion The intake of grain foods represented a substantial part of the Latin American population's diet, but the intake of foods containing whole grains was extremely low in all assessed countries.
