    (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.

    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.
