    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.

    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.
