    Argentina´s global matrix 4.0 report card results on physical activity for children and adolescents
    (Society for Physical Activity and Health, 2024-11-12) Lobo, Pablo; Holgado, Micaela; López, Laura; Baigún, Valeria; De Roia, Gabriela
    The objective of the Argentine Global Matrix 4.0 Report Card was to synthesize the available national evidence on topics related to physical activity and health of children and adolescents and, based on that evidence, to assign a grade to some related indicators. Methods: The Report Card working group reviewed and compiled the best available evidence on the indicators developed by Active Healthy Kids Global Alliance. Each of the 12 grades (for 10 core and 2 optional indicators) were based on the percentage of children and adolescents meeting a benchmark established in the Global Matrix grading rubric: These grades could range from A+ (best) to F (worst), or an incomplete was assigned when evidence was insufficient or inadequate for grading. The grades were subsequently reviewed and harmonized by 2 independent Active Healthy Kids Global Alliance reviewers. Results: Overall Physical Activity, Sedentary Behavior, and Government, all received a grade of D+. Organized Sport and Physical Activity and Community and Environment each received a grade of C−. Obesity received a grade of C+. Active Play, Active Transportation, Physical Fitness, Family and Peers, School, and Sleep were graded as incomplete. Conclusions: Only half of the indicators were able to be graded, as the other half were inconclusive due to lack of evidence. This leaves a gap and thus a challenge at the national level to improve research, surveillance systems, and policies to promote physical activity during childhood and adolescence.

    Changes in sitting time, screen exposure and physical activity during COVID-19 lockdown in South American adults : a cross-sectional study
    (Multidisciplinary Digital Publishing Institute, Suiza, 2021) Sadarangani, Kabir P.; De Roia, Gabriela; Lobo, Pablo; Chavez, Robinson; Meyer, Jacob; Cristi-Montero, Carlos; Martinez-Gomez, David; Ferrari, Gerson; Schuch, Felipe B.; Gil-Salmerón, Alejandro; Solmi, Marco; Veronese, Nicola; Alzahrani, Hosam; Grabovac, Igor; Caperchione, Cristina M.; Tully, Mark A.; Smith, Lee
    The worldwide prevalence of insufficient physical activity (PA) and prolonged sedentary behavior (SB) were high before the coronavirus (COVID-19) pandemic. Measures that were taken by governments (such as home confinement) to control the spread of COVID-19 may have affected levels of PA and SB. This cross-sectional study among South American adults during the first months of COVID-19 aims to (i) compare sitting time (ST), screen exposure, moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA) before and during lockdown to sociodemographic correlates and (ii) to assess the impact of lockdown on combinations of groups reporting meeting/notmeeting PA recommendations and engaging/not-engaging excessive ST (≥7 h/day). Bivariate associations, effect sizes, and multivariable linear regressions were used. Adults from Argentina (n = 575) and Chile (n = 730) completed an online survey with questions regarding demographics, lifestyle factors, and chronic diseases. Mean reductions of 42.7 and 22.0 min./day were shown in MPA and VPA, respectively; while increases of 212.4 and 164.3 min./day were observed in screen and ST, respectively. Those who met PA recommendations and spent <7 h/day of ST experienced greatest changes, reporting greater than 3 h/day higher ST and more than 1.5 h/day lower MVPA. Findings from the present study suggest that efforts to promote PA to South American adults during and after COVID-19 restrictions are needed.

    Characterization of physical activity levels in female breast cancer survivors : relationship with Lymphedema (AtiLinf)
    (International Society for Physical Activity and Health, 2025) Ralheta Duarte, Alice; Martinho Neto, Carla; Prates, Leonor; Lobo, Pablo; Tomás, María Teresa
    The development of lymphedema (LE) is a major concern in breast cancer treatment, and it is crucial to understand the best ways to prevent and treat it. Physical activity has shown to be effective, safe, and feasible in controlling complications arising from treatments, as well as improving function and quality of life in breast cancer survivors. This study aimed to investigate the relationship between physical activity with grip strength and LE development in breast cancer survivors. A cross-sectional analytical study was conducted and women who had survived breast cancer between 1 and 5 years after surgery were selected. Participants completed the International Physical Activity Questionnaire Short Form, the volume of upper limb (UL) was measured by perimetry, handgrip strength was assessed with the JAMAR dynamometer, and the Actigraph accelerometer was placed on the waist. It was found that 50% of the sample was overweight, 28.3% were obese, and 52% of the participants had grip strength below the recommended level. They had an average energy expenditure of 1.2 (0.1) metabolic equivalents, 8.3 (1.8) hours/day of sedentary activity, and spent an average of 61% of their awake time in sedentary activity per day. Significant correlations were found between grip strength on the affected side and the difference in volume between the UL (rp = −.303, P = .041) as well as between body mass index (BMI) and the difference in volume between the UL (rp = .341; P = .020). Moreover, a significant correlation between BMI and the volume of the affected UL was found (rp = .848, P = .000). BMI and grip strength of the affected side were identified as significant predictors of LE, both with P values less than .05. Although physical activity cannot directly prevent LE, it may contribute by helping to control BMI and promote higher levels of grip strength, both of which are important factors in the prediction of LE.

    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
    (Sports Medicine Australia, Australia, 2023) Sadarangani, Kabir P.; Schuch, Felipe B.; De Roia, Gabriela; Martinez-Gomez, David; Chavez, Robinson; Lobo, Pablo; Cristi-Montero, Carlos; Werneck, André O.; Alzahrani, Hosam; Ferrari, Gerson; Ibanez, Agustín; 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 andvigorous 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 depression (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.

    The Global Matrix 4.0 on physical activity (PA) for children and adolescents was developed to achieve a comprehensive understanding of the global variation in children’s and adolescents’ (5–17 y) PA, related measures, and key sources of influence. The objectives of this article were (1) to summarize the findings from the Global Matrix 4.0 Report Cards, (2) to compare indicators across countries, and (3) to explore trends related to the Human Development Index and geo-cultural regions. Methods: A total of 57 Report Card teams followed a harmonized process to grade the 10 common PA indicators. An online survey was conducted to collect Report Card Leaders’ top 3 priorities for each PA indicator and their opinions on how the COVID-19 pandemic impacted child and adolescent PA indicators in their country. Results: Overall Physical Activity was the indicator with the lowest global average grade (D), while School and Community and Environment were the indicators with the highest global average grade (C+). An overview of the global situation in terms of surveillance and prevalence is provided for all 10 common PA indicators, followed by priorities and examples to support the development of strategies and policies internationally. Conclusions: The Global Matrix 4.0 represents the largest compilation of children’s and adolescents’ PA indicators to date. While variation in data sources informing the grades across countries was observed, this initiative highlighted low PA levels in children and adolescents globally. Measures to contain the COVID-19 pandemic, local/international conflicts, climate change, and economic change threaten to worsen this situation.

    The global matrix of physical activity in children and adolescents in Latin America : trends, successes and challenges in practice and surveillance
    (Pan American Health Organization, 2025) Bizzozero-Peroni, Bruno; Tremblay, Mark S.; Aubert, Salomé; González, Silvia A.; Santos Silva, Diego Augusto; López-Taylor, Juan; Lobo, Pablo; De Roia, Gabriela; Sarmiento, Olga L.; Aguilar-Farias, Nicolas; Andrade Tenesaca, Susana; Galaviz, Karla I.; Brazo-Sayavera, Javier
    Objective. To synthesize the grades of physical activity (PA) indicators for children and adolescents (5–17 years) in Latin American countries; explore the social determinants of health (SDoH) for PA indicators; and identify strengths, weaknesses, opportunities, and threats to improve PA levels. Method. Participating Latin American countries graded a set of common PA indicators following the harmonized methodology established by the Global Matrix initiative. Cross-sectional (2014, 2016, 2018, 2022) and time trend (2018–2022) data were synthesized within and between countries for each PA indicator. PA data were also synthesized according to their SDoH. Report card team leaders completed a questionnaire to identify strengths, weaknesses, opportunities, and threats (SWOT) to improve PA grades. Results. Eight Latin American countries (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Uruguay, and Venezuela) participated in at least one of the four editions of the Global Matrix initiative. Across all PA indicator grades in the region (n = 193), 35.2% received a “D” (20%–39% success rate), the most frequent grade. Incomplete information was reported in 27.5% of the indicators. A 9.3% improvement was observed in the regional average score of all PA indicators analyzed over time. While source-of-influence indicators improved by 28.1%, behavioral indicators declined by 6.2%. The need for further analyses disaggregated by SDoH, such as sex, was identified. Conclusion. Latin American countries reported poor grades on PA indicators for children and adolescents. Contrasted progress was observed between the behavioral and source of influence indicator groups. Improved surveillance systems and greater country-level investment in PA data collection are urgently needed to enhance comparability and guide regional action.

    How to reduce sedentary behavior at all life domains
    (IntechOpen, 2021) López Torres, Olga; Lobo, Pablo; Baigún, Valeria; De Roia, Gabriela
    Lifestyle has changed in the last century increasingly promoting sedentary behaviors. Prolonged sitting time is related to increased all-cause mortality risk. Therefore, scientific research aimed at understanding the effects of sitting on health has increased to find effective interventions that can be carried out in life domains (study, work, transport, and free time). The interaction between physical activity and sitting time plays a key role in the development of strategies to promote physical activity practice and reduce sedentary behavior. Accepting that the modern societies incite to spend long periods seated, the aim seems to find a balance between all the areas during the 24 h of the day. Maintaining sleep time, reducing screen leisure time to 3 h/day, and breaking prolonged sedentary time for 2–3 min every 30 min-1 h of sitting, as well as reaching the physical activity recommendation may help counteract the potential negative effect of too much sitting time. Governments must provide active free time options to promote active leisure time and help reduce screen time. At workplaces, managers and companies should encourage sitting breaks and work standing options, and for the special population such as children or older adults, new strategies must be considered to reduce sitting time.

    Inequalities in healthy behaviors during the COVID-19 pandemic in children from public and private schools of Buenos Aires
    (Sociedade Brasileira de Atividade Física e Saúde, Brasil, 2025) De Roia, Gabriela; Lobo, Pablo; Holgado, Micaela; Baigún, Valeria
    Objective: To compare physical activity (PA), screen time (ST), and sleep behaviors before and during the mandatory preventive social isolation (ASPO, for its acronym in Spanish) due to COVID-19 among children attending public and private primary schools in the Greater Buenos Aires metropolitan area. Methods: A total of 379 adult caregivers of children attending public and private primary schools completed an online survey on PA, ST, and sleep behaviors before and during ASPO. School type was used as an indicator of socioeconomic status, with private schools’ students considered more privileged than public schools’ students. Results: For both groups, ASPO resulted in a reduction in PA (-43%) and an increase in ST (79.9%). Children attending private schools had the worst results, since they started with better behaviors (PA pre vs during: 3.5 ± 1.3 vs 1.9 ± 2.0 days/week; ST pre vs during: 2.1 ± 0.6 vs 3.8 ± 1.0 days/week) compared to the children attending public schools (PA pre vs during: 3.1 ± 1.8 vs 1.8 ± 1.5 days/week; ST pre vs during: 2.4 ± 0.9 vs 3.6 ± 1.3 days/week). Sleep increased by 7.6% with a shift towards later bed and wake-up times, with public schools’ students being more affected. Conclusion: ASPO restrictions led to unfavorable changes in PA, ST and sleep behaviors among children attending public schools and private schools. ASPO evened out the pre-pandemic differences between public schools and private schools’ students in PA and ST behaviors.

    (Multidisciplinary Digital Publishing Institute, Suiza, 2024-06-22) Barakat Carballo, Rubén; Silva José, Cristina; Sánchez Polan, Miguel; Zhang, Dingfeng; Lobo, Pablo; De Roia, Gabriela; Montejo, Rocío
    The repercussions of childhood overweight and obesity are multifaceted, extending beyond the realm of physiology and giving rise to psychological and emotional disturbances in affected children. The precise effects of gestational physical activity (PA) on parameters related to childhood overweight and obesity remain inadequately understood. The aim of this study (Registration CRD42022372490) was to evaluate the literature regarding the influence of PA during pregnancy on the risk of childhood overweight and obesity. Materials and Methods: Only randomized controlled trials (RCTs) were considered for inclusion. Determinant parameters of childhood obesity were analyzed. A total of 30 studies involving 16,137 pregnant women were examined. Five meta-analyses about the effects of PA during pregnancy on determinants of childhood overweight and obesity were conducted. Results: Although favorable trends were observed, Meta-Analyses showed no statistical differences in the effects of PA on weight at birth (Z = 0.03, p = 0.97), Ponderal Index at birth (Z = 0.64, p = 0.52), Macrosomia and Large for Gestational Age at birth (Z = 0.93, p = 0.35), children’s BMI (Z = 0.78, p = 0.44), weight (Z = 0.50, p = 0.62), and skinfold thicknesses (Z = 0.45, p = 0.65). Conclusions: The engagement in physical activity during pregnancy exhibits a favorable trend in parameters associated with childhood overweight and obesity while presenting no adverse effects on such outcomes.

    Punto de quiebre del doble producto como indicador de transición metabólica durante el ejercicio en pacientes coronarios
    (Federación Argentina de Cardiología, 2016) Resnik, Miguel; De Roia, Gabriela; Lobo, Pablo; Peralta, Liliana; Saccone, Flavia; Puga, Leopoldo; Taurozzi, Sergio; Moreno, Gustavo
    El umbral anaeróbico ha sido utilizado como un buen indicador de capacidad funcional y de implicancias pronósticas en pacientes cardíacos. El objetivo fue evaluar un método no invasivo como el punto de quiebre del doble producto (PQDP) durante el ejercicio, punto en el cual se produjo un aumento claro y sostenido de la pendiente de doble producto (DP) durante la prueba de esfuerzo incremental. DP= frecuencia cardiaca (FC) x presión arterial sistólica (PAS), que podría ser aplicado para el entrenamiento físico y de información pronóstica en pacientes con enfermedad coronaria (EC). Material y métodos. Se evaluaron 33 hombres y 9 mujeres de 64,8 ± 7,6 años con EC documentada, clínicamente estables con tratamiento médico y en ritmo sinusal. Todos realizaron una PEG en cinta deslizante. El ejercicio consistió en un período inicial de entrada en calor (1 km/h) con cargas crecientes por etapa de 0,4 km/h cada minuto hasta el límite de tolerancia del sujeto. El consumo de oxígeno (VO2) se midió con un sistema portátil (COSMED), la FC con un ECG de 12 derivaciones y la presión arterial por esfigmomanometría en cada etapa. El DP vs VO 2 fue sometido a 3 evaluadores independientes para la determinación visual del VT1 y PQDP. El test de Student se utilizó para comparar velocidad (km/h) en VT1 y PQDP y el coeficiente de correlación de Pearson entre ambos parámetros (p<0,05). Resultados. Los pacientes no tuvieron síntomas. Se determinó el VT1 y PQDP en todos ellos. La velocidad del PQDP fue de 2,6 ± 0,5 km/h y la velocidad en VT1 2,6 ± 0, 6 km/h, sin diferencias significativas entre ambos. Encontramos una correlación positiva comparando VT1 vs PQDP (r2=0,6). Conclusiones. Se pudo medir el PQDP en pacientes coronarios con una buena correlación positiva con VT1
