    Cystic fibrosis (CF) is an inherited, progressive, multisystem disease. Better physical capacity may slow disease progression, thus improving prognosis and survival. The objective of this research was to evaluate the physical capacity of children admitted to the National CF Program of the Metropolitan Region, Chile. Patients and Method: A multicenter, cross-sectional study design was used. The inclusion criteria were children aged 6 to 12 years enrolled in the National CF Program; Tanner sexual maturity stage I, no respiratory exacerbations in the last 30 days, and no musculoskeletal pathologies. The maximum aerobic capacity was assessed through the peak oxygen uptake (VO2 peak) and determined with an incremental protocol in a magnetic cycle ergometer connected to an ergo-spirometer with which, at the same time, respiratory gases, oxygen consumption and carbon dioxide production values every 30 seconds, anaerobic threshold, and maximum workload were analyzed. The values of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, and forced expiratory flows between 25% and 75% of vital capacity were assessed through ergo-spirometry. At the beginning of the ergo-spirometry, arterial oxygen saturation, respiratory rate, heart rate, blood pressure, tidal volume and the perception of lower extremity fatigue and dyspnea were recorded using the modified Borg scale. The test lasted approximately 10 minutes. Results: The clinical records of 43 children collected from six health centers were reviewed. Out of these, 29 children met inclusion criteria, and 23 were recruited. Two children were unable to participate, reducing the final subject group to 21 (13 males, 8 females). The mean age was 8.8 ± 2 years; weight 30.5 ± 10.9 kg; height 1.32 ± 0.11 m; and body mass index 17.1 ± 3.5 (z-score 0.01 ± 1.34). More than half of the children (61%) had normal weight. The obtained VO2 peak was 43.7 ± 6.5 ml/min/kg (106.7 ± 19.8% of the predictive values). Only 10% of the children had values lower than those predicted by sex and age. No correlations were found between VO2 peak and anthropometric and pulmonary function variables. Conclusion: Most of the evaluated children (90%) had physical capacity similar to healthy subjects by sex and age. © 2018, Sociedad Chilena de Pediatria. All rights reserved.

    Exchanging screen for non-screen sitting time or physical activity might attenuate depression and anxiety: A cross-sectional isotemporal analysis during early pandemics in South America
    (Elsevier Ltd, 2023-06) Sadarangani, Kabir P.; Barreto Schuch, Felipe; De Roia, Gabriela; Martínez-Gomez, David; Chávez, Róbinson; Lobo, Pablo; Cristi-Montero, Carlos; Werneck, André O.; Alzahrani, Hosam; Ferrari, Gerson; Ibanez, Agustin; Silva, Danilo R.; Von Oetinger, Astrid; Matias, Thiago S.; Grabovac, Igor; Meyer, Jacob
    Objectives: To examine the theoretical substitutions of screen exposure, non-screen sitting time, moderate and vigorous physical activity with depressive and anxiety symptoms in South American adults during the COVID 19 pandemic. Design: A cross-sectional study during the first months of the COVID-19 pandemic with data from 1981 adults from Chile, Argentina, and Brazil. Methods: Depressive and anxiety symptoms were assessed using the Beck Depression and Anxiety Inventories. Participants also reported physical activity, sitting time, screen exposure, sociodemographic, and tobacco use data. Isotemporal substitution models were created using multivariable linear regression methods. Results: Vigorous physical activity, moderate physical activity, and screen exposure were independently associated with depression and anxiety symptoms. In adjusted isotemporal substitution models, replacing 10 min/day of either screen exposure or non-screen sitting time with any intensity of physical activity was associated with lower levels of depressive symptoms. Improvements in anxiety symptoms were found when reallocating either screen exposure or non-screen sitting time to moderate physical activity. Furthermore, replacing 10 min/day of screen exposure with non-screen sitting time was beneficially associated with anxiety (B = −0.033; 95 % CI = −0.059, −0.006) and de pression (B = −0.026; 95 % CI = −0.050, −0.002). Conclusions: Replacement of screen exposure with any intensity of physical activity or non-screen sitting time could improve mental health symptoms. Strategies aiming to reduce depressive and anxiety symptoms highlight physical activity promotion. However, future interventions should explore specific sedentary behaviors as some will relate positively while others negatively. © 2023 The Authors.

    Results from Chile's 2016 report card on physical activity for children and youth
    (Human Kinetics Publishers Inc., 2016-11) Aguilar-Farias, Nicolas; Cortinez-O'Ryan, Andrea; Sadarangani, Kabir P.; Von Oetinger, Astrid; Leppe, Jaime; Valladares, Macarena; Balboa-Castillo, Teresa; Cobos, Carolina; Lemus, Nicolas; Walbaum, Magdalena; Cristi-Montero, Carlos
    Background: The 2016 Chilean Report Card on Physical Activity for Children and Youth is a review of the evidence across indicators of behaviors, settings, and sources of influence associated with physical activity (PA) of Chilean children and youth. 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.
