Published: January 2022   Journal: Sport Sciences for Health

Children have a higher chance of decreasing health-related physical fitness during periods of school lockdown due to pandemic situations such as with COVID-19 disease. This paper aims to establish the changes in children’s self-perceived physical fitness (SPPF) during pandemic COVID-19 social distancing in a school lockdown and to describe the individual prevalence of changes in SPPF according to sex. It is an intervention study with a convenient sample, 67 children (6–13 years old; 50.7% girls). An intervention occurred according to the Brazilian Base Nacional Comum Curricular (BNCC) and the State Education Secretary orientations for remote Physical Education classes. SPPF was evaluated through a questionnaire (QAPA). Generalized estimative equations (GEE) and the prevalence of changes in individual score delta (Δ) from baseline to follow-up determined the effects.

Hermano Alexandre Lima Rocha; Luciano Lima Correia; Álvaro Jorge Madeiro Leite (et al.)

Published: January 2022   Journal: Journal of Children and Media
The present study assessed changes in screen time exposure among 3–6-year-old children in Ceará, Brazil, in 2017 and in 2020 during the pandemic. Data from a state-wide repeated cross-sectional survey were analyzed. The COVID impact research was conducted by phone interviews. American Academy of Pediatrics (AAP) and World Health Organization (WHO) guidelines were used to define elevated screen exposure. During the COVID-19 pandemic, the proportion of children with screen exposure above recommended levels was 96.8% among 3–4-year-old and 84.2% among 5–6-year-old children. There was a significant increase in proportion of 3–4-year-old children with elevated screen time (risk difference 15.8%; 95% confidence interval (CI): 12.3–19.2; p-value < 0.001). Children participating in remote learning activities had significantly lower television time with a mean difference of −0.8 hours daily (95% CI −0.3 – −1.3; p-value: 0.003) as compared to children not participating in remote learning. The necessary COVID-19 response measures appear to increase screen time among 3–6-year-old children in Ceará, Brazil. Interventions to reduce excess screen time, potentially participation in remote early learning activities should be developed and evaluated in Brazil.

Eduardo A. Oliveira; Ana Cristina Simões e Silva; Maria Christina L. Oliveira (et al.)

Published: January 2022   Journal: The Journal of Pediatrics

To evaluate the severity and clinical outcomes of the SARS-CoV-2 gamma variant in children and adolescents hospitalized with COVID-19 in Brazil. In this observational retrospective cohort study, we performed an analysis of all 21,591 hospitalized patients aged < 20 years with confirmed SARS-CoV-2 infection registered in a national database in Brazil. The cohort was divided into two groups according to the predominance of SARS-CoV-2 lineages (WAVE1, n = 11,574 and WAVE2, n = 10,017). The characteristics of interest were age, sex, geographic region, ethnicity, clinical presentation, and comorbidities. The primary outcome was time to death, which was evaluated by competing-risks analysis, using cumulative incidence function. A predictive Fine-Gray competitive risks model was developed based on WAVE1 cohort with temporal validation in WAVE2 cohort.

Infants’ and toddlers’ digital media use and mothers’ mental health: a comparative study before and during the COVID-19 pandemic

Bruna Gabriella Pedrotti; Manoela Yustas Mallmann; Carla Regina Santos Almeida (et al.)

Published: December 2021   Journal: Infant Mental Health Journal
This study compared children's and mothers’ digital media use and mothers’ mental health in two samples: one accessed before (Group 1; N = 257; M = 33.18 years; SD = 4.79) and the other accessed during (Group 2; N = 256; M = 33.51 years; SD = 4.96) the COVID-19 pandemic in Brazil. Mothers of children up to 3 years old (Group 1: M = 17.95 months, SD = 9.85; Group 2: M = 16.48 months, SD = 10.15) answered an online survey. Bivariate analysis, factorial ANOVA tests, and multiple linear regression were performed. Results suggest that mothers’ and children's media use duration was higher during the pandemic only among children over 12 months. Mothers’ media use duration (β = .18) and mothers’ intention to offer media (β = .23) contributed to the explanation of children's media use duration (F(4, 474) = 16.81; p < .001; R2 = .12; R2 adjusted = .117). Higher mothers’ common mental disorders symptoms were also positively correlated to mothers’ intention to offer media to children both before and during the pandemic. Results suggest that interventions focusing on infants and toddlers screen time reduction should target maternal aspects such as mental health, maternal screen time, and intention to offer media, taking into account the mothers’ needs when planning these actions.
