Published: August 2022   Journal: The Lancet Infectious Diseases
Little is known about vaccine effectiveness over time among adolescents, especially against the SARS-CoV-2 omicron (B.1.1.529) variant. This study assessed the associations between time since two-dose vaccination with BNT162b2 and the occurrence of symptomatic SARS-CoV-2 infection and severe COVID-19 among adolescents in Brazil and Scotland. It did test-negative, case-control studies in adolescents aged 12–17 years with COVID-19-related symptoms in Brazil and Scotland. It linked records of SARS-CoV-2 RT-PCR and antigen tests to national vaccination and clinical records. It excluded tests from individuals who did not have symptoms, were vaccinated before the start of the national vaccination programme, received vaccines other than BNT162b2 or a SARS-CoV-2 booster dose of any kind, or had an interval between their first and second dose of fewer than 21 days. Additionally, it excluded negative SARS-CoV-2 tests recorded within 14 days of a previous negative test, negative tests recorded within 7 days after a positive test, any test done within 90 days after a positive test, and tests with missing sex and location information. Cases (SARS-CoV-2 test-positive adolescents) and controls (test-negative adolescents) were drawn from a sample of individuals in whom tests were collected within 10 days of symptom onset. It estimated the adjusted odds ratio and vaccine effectiveness against symptomatic COVID-19 for both countries and against severe COVID-19 (hospitalisation or death) for Brazil across fortnightly periods.

Published: August 2022   Journal: Applied Sciences
Limitations in the use of public spaces have impacted the frequency and duration of movement behaviours (physical activity, sedentary behaviour, sleep) and outdoor activities of children and adolescents. Whether pandemic-induced changes in movement behaviours are related to the health-related quality of life (HRQoL) of children and adolescents is unknown. The aim of the current study was to examine the association between meeting 24 h movement guidelines and HRQoL during the COVID-19 lockdown among children and adolescents. Data from 1099 3–17-year-old children and adolescents from Spain and Brazil were analysed. An online questionnaire was used to collect parent-reported information concerning physical activity, screen time, and sleep duration. For the assessment of HRQoL, the EQ-5D-Y proxy version was used.

Published: August 2022   Journal: Nature Communications
Although severe COVID-19 in children is rare, they may develop multisystem inflammatory syndrome, long-COVID and downstream effects of COVID-19, including social isolation and disruption of education. Data on the effectiveness of the CoronaVac vaccine is scarce during the Omicron period. In Brazil, children between 6 to 11 years are eligible to receive the CoronaVac vaccine. This research conducted a test-negative design to estimate vaccine effectiveness using 197,958 tests from January 21, 2022, to April 15, 2022, during the Omicron dominant period in Brazil among children aged 6 to 11 years.

Published: August 2022   Journal: International Journal of Health Science

Childhood obesity is a nutritional disorder considered a serious public health problem worldwide because it is responsible for a large part of the emergence of chronic degenerative diseases and, consequently, raises the levels of morbidity and mortality. The beginning of the COVID-19 pandemic contributed to the increase in the rates of this comorbidity, as the established transmission containment measures led to a reduction in physical activity, an increase in screen time and anxiety-related disorders. Thus, the Healthy Lifestyle at School extension project, developed at the Faculty of Medicine of the Federal University of Cariri (UFCA), whose objective is to act in the identification, prevention and treatment of overweight and obesity in children and adolescents, recognized the need adapting face-to-face activities to the remote context. An account was created on the social network Instagram in order to alert about the problem and with the objective of reaching the target audience through educational, preventive and control measures against childhood obesity. The study is a qualitative analysis, of the experience report type, based on data obtained between April and September of the year 2020 on the Project’s social media page. It can be seen from this study that the challenge for extension projects to remain as guides for good health practices and remote knowledge production showed satisfactory results with the use of the social network as a tool for health promotion and education.

Published: July 2022   Journal: The Lancet Regional Health - Americas

Data regarding the geographical distribution of cases and risk factors for COVID-19 death in children and adolescents are scarce. We describe the spatial distribution of COVID-19 cases and deaths in paediatric population and their association with social determinants of health in Brazil. This is a population-based ecological study with a spatial analysis of all cases and deaths due to COVID-19 in Brazil among children and adolescents aged 0–19 years from March 2020 to October 2021. The units of analysis were the 5570 municipalities. Data on COVID-19 cases and deaths, social vulnerability, health inequities, and health system capacity were obtained from publicly available databases. Municipalities were stratified from low to very high COVID-19 incidence and mortality using K-means clustering procedures, and spatial clusters and relative risks were estimated using spatial statistics with Poisson probability models. The relationship between COVID-19 estimates and social determinants of health was explored by using multivariate Beta regression techniques.

Published: July 2022   Journal: Portuguese Journal of Public Health
The COVID-19 pandemic may affect youth’s physical and mental well-being, partially because of the countries’ rules to contain the virus from spreading. However, there is still uncertainty about the impact of physical distancing on youth’s mental health. This study aimed to estimate the prevalence of feeling agitated, anxious, down, sad, or low mood (FNF) due to physical distance measures and verify which factors are associated with young Portuguese and Brazilian people. It used cross-sectional data from the instrument “COVID-19 Barometer: Social Opinion” in Portugal (March 2020 and September 2021) and from “COVID-19 Social Thermometer” in Brazil (August 2020 to April 2021); these surveys included data regarding the health and socioeconomic impact on the population.

Published: June 2022   Journal: Journal of Media Literacy Education
In a globalized world, critical media literacy is imperative when selecting the content we consume amid countless offers. Therefore, the purpose of this case study is to analyze which resources 3rd year high school students (16-17 years old) from an English as a Second Language class in Brazil use in the construction of authorial journalistic articles demystifying fake news about COVID-19 and if the interventions conducted previous to the task were helpful in their process of developing critical media literacy. To this end, firstly students analyzed news about COVID-19 from international websites; secondly, they discussed aspects of a video that circulated widely in WhatsApp chat groups; and, finally, they produced journalistic articles demystifying popular fake news about COVID-19 in Brazil.
