    (2020) Aguilar-Farias, Nicolas; Miranda-Marquez, Sebastian; Martino-Fuentealba, Pia; Sadarangani, Kabir P.; Chandia-Poblete, Damian; Mella-Garcia, Camila; Carcamo-Oyarzun, Jaime; Cristi-Montero, Carlos; Rodriguez-Rodriguez, Fernando; Delgado-Floody, Pedro; Von Oetinger, Astrid; Balboa-Castillo, Teresa; Pena, Sebastian; Cuadrado, Cristobal; Bedregal, Paula; Celis-Morales, Carlos; Garcia-Hermoso, Antonio; Cortinez-O'Ryan, Andrea
    Background: The study summarizes the findings of the 2018 Chilean Report Card (RC) on Physical Activity (PA) for Children and Adolescents and compares the results with the first Chilean RC and with other countries from the Global Matrix 3.0. Methods: A Research Work Group using a standardized methodology from the Global Matrix 3.0 awarded grades for 13 PA-related indicators based on the percentage of compliance for defined benchmarks. Different public data sets, government reports, and papers informed the indicators. Results: The grades assigned were for (1) "behaviors that contribute to overall PA levels": overall PA, D-; organized sport participation, D-; active play. INC; and active transportation, F; (2) "factors associated with cardiometabolic risk": sedentary behavior, C-; overweight and obesity, F; fitness, D; sleep, INC; and (3) "factors that influence PA": family and peers, F; school, D; inclusion, INC; community and built environment, B; government strategies and investments, B-. Conclusions: Chile's grades remained low compared with the first RC. On the positive side, Chile is advancing in environmental and policy aspects. Our findings indicate that the implementation of new strategies should be developed through collaboration between different sectors to maximize effective investments for increasing PA and decreasing sedentary time among children and adolescents in Chile.

    Bikesharing and ordinary cyclists from Chile: Comparing trips, attitudes, and health-behaviours
    (2024) Mora, Rodrigo; Miranda Marquez, Sebastián; Truffello Robledo, Ricardo; Sadarangani, Kabir P.; CEDEUS (Chile)
    Bikesharing helps citizens solve “the last mile” problem actively and healthily. However, these schemes tend to be located in the affluent and central areas of cities and often demand users to pay by credit or debit cards that are typically out of reach for poor groups, especially in developing countries. Consequently, bikesharing tends to reproduce existing inequalities in cities, leaving vulnerable groups and those living in poor areas with no option to ride bicycles. This study compares bikesharing users and ordinary cyclists from Santiago de Chile in terms of their sociodemographic characteristics, health status, transport-modal patterns, attitudes, and perceptions toward cycling and bikesharing infrastructure. In all, 1272 adult participants (569 bikesharing users and 703 ordinary cyclists, 63% males) responded to a 12-min survey in Santiago de Chile. The main findings show that bikesharing users reported higher educational levels and car ownership than ordinary cyclists, made shorter trips, and cycled less often than ordinary cyclists. However, using shared bikes permits them to comply with nearly 53% of their weekly physical activity recommendations, as nearly 40% of bikesharing trips would be otherwise made by car. Bikesharing users also tend to visit central areas of Santiago and rarely visit less central and affluent zones.

    Physical activity and daily steps cut offs points for overweight/obesity prevention among eight Latin American countries
    (2022) Ferrero-Hernandez, Paloma; Farias-Valenzuela, Claudio; Jofre-Saldia, Emilio; Marques, Adilson; Kovalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Cortes, Lilia Yadira; Garcia, Martha Yepez; Pareja, Rossina G.; Herrera-Cuenca, Marianella; Fisberg, Mauro; Silva, Danilo R.; Sadarangani, Kabir P.; Ferrari, Gerson
    This study aims to establish cut-off points for the number of minutes of physical activity intensity and the number of daily steps that identify overweight/obesity in adolescents, adults, and older adults. This study examined data from 2737 participants. Physical activity intensity and the number of daily steps were assessed using GT3X+ ActiGraph model accelerometers. Body mass index, waist-to-height ratio, and waist-to-hip ratio were used as indicators of overweight/obesity. The cut-off points for moderate-to-vigorous physical activity for the prevention of overweight/obesity according to body mass index in women ranged from 15.1 to 30.2 min/day; in men, the values were from 15.4 to 33.8 min/day. The lowest cut-off point for daily steps was established in the adolescent group for women and men (7304 and 5162). The highest value in women was 11,412 (51-65 years) and 13,234 in men (18-30 years). Results from measurements different from BMI, show average cut-off points for moderate-to-vigorous physical activity and daily steps of 29.1/8348 and 43.5/10,456 according to waist-to-height ratio; and results of 29.3/11,900 and 44.3/11,056 according to the waist-to-hip ratio; in women and men respectively. A more specific recommendation of physical activity and daily steps adjusted by sex and age range is suggested to prevent overweight/obesity.

    Walking and cycling, as active transportation, and obesity factors in adolescents from eight countries
    (2022) Ferrari, Gerson; Drenowatz, Clemens; Kovalskys, Irina; Gómez, Georgina; Rigotti Rivera, Attilio; Cortés, Lilia Y.; García, Martha Y.; Pareja, Rossina G.; Herrera-Cuenca, Marianella; Del’Arco, Ana P.; Peralta, Miguel; Marques, Adilson; Leme, Ana C. B.; Sadarangani, Kabir P.; Guzmán-Habinger, Juan; Chaves, Javiera L.; Fisberg, Mauro
    Background: Evidence has shown that active transportation decreases obesity rates, but considering walking or cycling as separate modes could provide additional information on the health benefits in adolescents. This study aimed to examine the associations between walking and cycling as form active transportation and obesity indicators in Latin American adolescents. Methods: Population-based study with 671 adolescents (mean age: 15.9 [standard deviation: 0.8] years) from eight countries participating in the Latin American Study of Nutrition and Health/Estudio Latino Americano Nutrition y Salud (ELANS). Walking and cycling for active transportation were measured using the International Physical Activity Questionnaire long version. Body mass index, waist circumference, neck circumference, and relative fat mass were used as obesity indicators. Associations were estimated using logistic regression models for the pooled data adjusted for country, sex, age, socio-economic levels, race/ethnicity, leisure-time physical activity and energy intake. Results: Mean time spent walking and cycling was 22.6 (SD: 33.1) and 5.1 (SD: 24.1) min/day, respectively. The median values were 12.8 (IQR: 4.2; 25.7) and 0 (IQR: 0; 6.2) for walking and cycling. Participants reporting ≥ 10 min/week of walking or cycling for active transportation were 84.2% and 15.5%, respectively. Costa Rica (94.3% and 28.6%) showed the highest prevalence for walking and cycling, respectively, while Venezuela (68.3% and 2.4%) showed the lowest prevalence. There was no significant association between walking for active transportation and any obesity indicator. In the overall sample, cycling for ≥ 10 min/week was significantly associated with a lower likelihood of overweight/obesity based on BMI (OR: 0.86; 95%CI: 0.88; 0.94) and waist circumference (OR: 0.90; 95%CI: 0.83; 0.97) adjusted for country, sex, age, socio-economic level, race/ethnicity, leisure-time physical activity and energy intake compared to cycling for < 10 min/week. There were no significant associations between cycling for active transportation and neck circumference as well as relative fat mass. Conclusions: Cycling for active transportation was negatively associated with obesity indicators, especially body mass index and waist circumference. Programs for promoting cycling for active transportation could be a feasible strategy to tackle the high obesity rates in adolescents in Latin America.
