COVID-19 and children’s screen time in Ceará, Brazil: a repeated cross-sectional survey

AUTHOR(S)
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.

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

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.

Published: December 2021   Journal: Special Care In Dentistry

This study aimed to report the perception of parents of children/adolescents with autism regarding the parents’ fear of the pandemic by COVID-19. Also, to report children's fear about the use of individual protective equipment (IPE) in dental appointments, and the impact on the daily routine during the pandemic. A cross-sectional study through an open online survey was addressed to parents of children/adolescents autistic, aged between 3 and 18 years. The questionnaire had questions regarding the parents’ fear of the COVID-19 pandemic, the parents’ perception about the children/adolescents’ fear of the use of IPEs at dental care, and the impact of the daily routine during the pandemic and social impact after the pandemic. Parents' reports on the degree of ASD (mild, moderate, and severe) of the child/adolescent. A total of 1001 responses were obtained. 50.35% of parents had high fear of the pandemic by COVID-19, 59.34% believe that children/teenagers will be afraid of the dentist's IPE and 61.64% responded that the COVID-19 pandemic had a high impact on the daily routine of children/adolescents with ASD.

Published: December 2021   Journal: Psychiatry Research Communications
This study aimed to assess the factors associated with frequent sadness and nervousness in Brazilian adolescents, during the Covid-19 pandemic, in 9470 adolescents (aged 12–17 years), interviewed from June 27 to September 17, 2020. Prevalences and prevalence ratios were estimated according to socio-demographic variables and factors related to family, school, friends, and health. Brazilian adolescents often felt sad (32.4%) and nervous (48.7%). Higher prevalences of these feelings were related to: being female; aged 15–17 year; from families with financial difficulties; having learned little or nothing with remote education; missing friends; having few friends; family disagreements; having regular/bad health before the pandemic; and worsened health and sleep during the pandemic. Higher prevalence of nervousness was also found in adolescents who worked before the pandemic and those who reported lack of concentration and not knowing if they had COVID-19. Sadness and nervousness in Brazilian adolescents is high and the need for action by the government, schools, health services, and parents to mitigate the impact of the pandemic on the physical and mental health of adolescents. Special attention must be paid to adolescents with previous health problems and those belonging to the most socially vulnerable population.

This study aims to identify the hidden orphans and to reinforce existing monitoring systems. Orphanhood is a public health issue, and it primarily evidences existing geopolitical tensions. Thus, this study emphasises the strong naturalisation of social inequalities and the extreme vulnerability of children and adolescents impacted by the COVID-19 pandemic. COVID-19 continues to tear families apart, leaving the children of deceased parents with even fewer options than before the pandemic. In Brazil, one child is orphaned by COVID-19 every 5 min. This is an alarming estimate, especially in the most vulnerable and underprivileged regions of the country, such as the North and Northeast. Current evidence emphasises that at every three million deaths due to the pandemic, more than 1.5 million children lose their mothers, fathers or primary caregivers (usually grandparents). This may be very traumatic for children. In this context, Brazil is the second country in the world with the highest number of COVID-19 deaths, reducing caregiving options among family members.

Exercise has been suggested to prevent deterioration of health-related quality of life (HRQL) and overall health in pediatric rheumatologic diseases during the COVID-19 pandemic. Herein we describe the effects of a 12-week, home-based, exercise program on overall health and quality of life among quarantined patients with juvenile dermatomyositis (JDM). Method: This prospective, quasi-experimental, mixed methods (qualitative and quantitative) study was conducted between July and December 2020, during the most restricted period of COVID-19 pandemic in Brazil. The homebased exercise program consisted of a 12-week, three-times-a-week, aerobic and strengthening (bodyweight) training program. Qualitative data were systematically evaluated. Strengths and Difficulties Questionnaire (SDQ), Pediatric Quality of Life Inventory (PedsQOL) and Pittsburgh Sleep Quality Index (PSQI) evaluate symptoms of mental health disorder, HRQL, and quality of sleep.
