Ítem Alarming low physical activity levels in Chilean adults with disabilities during COVID-19 pandemic: a representative national survey analysis(Frontiers Media S.A., 2023-06) Henríquez, Matías; Ramirez-Campillo, Rodrigo; Cristi-Montero, Carlos; Reina, Raul; Alvarez, Cristián; Ferrari, Gerson; Aguilar-Farias, Nicolas; Sadarangani, Kabir P.Background: People with disabilities usually face barriers to regularly engaging in physical activities. Estimating physical activity patterns are necessary to elaborate policies and strategies to facilitate active lifestyles, considering the particular access difficulties experienced by this population. Purpose: This study aimed (i) to describe the prevalence of physical activity levels and (ii) to examine the associations of physical activity levels with socio-demographic variables and type of disability in the 2020 Chilean National Physical Activity and Sports Habits in Populations with Disabilities (CNPASHPwD) survey during the coronavirus disease 19 (COVID-19) pandemic. Methods: Cross-sectional data from 3,150 adults (18–99 years old), 59.8% female, were analyzed from November to December 2020. Self-reported age, gender, type of disability (i.e., physical, visual, hearing, intellectual, or mixed), socio-economic status, area and zone of residence, and physical activity levels (0 min/week, < 150 min/week, ≥ 150 min/week) were obtained. Results: 11.9% of the participants were classified as active (≥ 150 min/week), and 62.6% declared no involvement in physical activity. A larger proportion of females (61.7%) did not meet the current guidelines (≥ 150 min/week of physical activity) in comparison with males (p < 0.001). Participants with visual and hearing disabilities were more likely to be active than those with other types of disabilities. Those living in the central and southern regions of Chile were more likely to be physically active than those from the northern region. Also, older participants, women, and those from lower socio-economic statuses were less likely to meet the physical activity guidelines. Conclusion: Alarmingly, nine out of ten participants were categorized as physically inactive, particularly women, older adults, and those with a low socioeconomic status. If the pandemic context moderated, the considerable prevalence of reduced physical activity levels deserves future exploration. Health promotion initiatives should consider these aspects, emphasizing inclusive environments and increasing opportunities to favor healthy behaviors, countering the COVID-19 effects.

The cogni-action project(MDPI, 2021-09) Cristi-Montero, Carlos; Ibarra-Mora, Jessica; Gaya, Anelise; Castro-Piñero, Jose; Solis-Urra, Patricio; Aguilar-Farias, Nicolas; Ferrari, Gerson; Rodriguez-Rodriguez, Fernando; Sadarangani, Kabir P.The first aim was to compare differences between school vulnerability groups, fitness levels, and their combination in adolescent cognitive performance. The second aim was to determine the mediation role of fitness in the association between school vulnerability and cognitive performance. A total of 912 Chilean adolescents aged 10–14 years participated in this study. The school vulnerability index (SVI) assigned by the Chilean Government was categorized into high-, mid-, or low-SVI. Adolescents were classified as fit or unfit according to their global fitness z-score computed from their cardiorespiratory (CRF), muscular (MF), and speed/agility fitness (SAF) adjusted for age and sex. A global cognitive score was estimated through eight tasks based on a neurocognitive battery. Covariance and mediation analyses were performed, adjusted for sex, schools, body mass index, and peak high velocity. Independent analyses showed that the higher SVI, the lower the cognitive performance (F(6,905) = 18.5; p < 0.001). Conversely, fit adolescents presented a higher cognitive performance than their unfit peers (F(5,906) = 8.93; p < 0.001). The combined analysis found cognitive differences between fit and unfit adolescents in both the high-and mid-SVI levels (Cohen’s d = 0.32). No differences were found between fit participants belonging to higher SVI groups and unfit participants belonging to lower SVI groups. Mediation percentages of 9.0%, 5.6%, 7.1%, and 2.8% were observed for the global fitness score, CRF, MF, and SAF, respectively. The mediation effect was significant between low-with mid-high-SVI levels but not between mid-and high-SVI levels. These findings suggest that an adequate physical fitness level should be deemed a protective social factor associated with bridging the cognitive gap linked to school vulnerability in adolescents. This favourable influence seems to be most significant in adolescents belonging to a more adverse social background. © 2021 by the authors.

Methods: A Research Work Group reviewed available evidence from publications, surveys, government documents and datasets to assign a grade for 11 indicators for PA behavior based on the percentage of compliance for defined benchmarks. Grades were defined as follows: A, 81% to 100% of children accomplishing a given benchmark; B, 61% to 80%; C, 41% to 60%; D, 21% to 40%; F, 0% to 20%; INC, incomplete data available to assign score. Results: Grades assigned were for i) ‘Behaviors that contribute to overall PA levels’: Overall PA, F; Organized Sport Participation, D; Active Play, INC; and Active Transportation, C-; ii) ‘Factors associated with cardiometabolic risk’: Sedentary Behavior, D; Overweight and Obesity, F; Fitness, F; and iii) ‘Factors that influence PA’: Family and Peers, D; School, D; Community and Built Environment, C; Government Strategies and Investments, C. Conclusions: Chile faces a major challenge as most PA indicators scored low. There were clear research and information gaps that need to be filled with the implementation of consistent and regular data collection methods.
