Resumo: A COVID-19, doença provocada pelo SARS-CoV-2 (novo coronavírus), surgiu na China em dezembro de 2019 e se espalhou rapidamente por todo o mundo. Diante desse cenário, este estudo objetivou identificar o impacto ou os efeitos da pandemia da COVID-19 na saúde dos adolescentes. Trata-se de uma revisão da literatura do tipo scoping review valendo-se das seguintes bases de dados: Web of Science; CINAHL; PsycINFO; SciELO; PUBCOVID19. O estudo seguiu as etapas propostas pelo Instituto Joanna Briggs para scoping reviews, e a questão que orientou os procedimentos adotados foi construída pelo acrônimo PCC (população; conceito; contexto). Foram incluídos 11 artigos na revisão. Clinicamente, os adolescentes apresentam os mesmos sintomas da COVID-19 que os adultos acometidos pela doença. Verificou-se que a pandemia e as medidas sanitárias adotadas para controlar a contaminação são associadas a problemas de saúde mental em adolescentes. Especificamente, os adolescentes têm vivenciado de forma negativa as medidas de distanciamento social e fechamento das escolas. Essas medidas também podem favorecer a ocorrência de violências ou comportamentos agressivos no contexto doméstico. Serviços de saúde que atendem a população adolescente precisaram reorientar as práticas de cuidado, adotando o modelo virtual em substituição ao cuidado presencial, e mesmo as pesquisas precisaram ser repensadas. Esta scoping review abordou um tema emergente em relação a uma população pouco considerada nos estudos sobre a COVID-19. Os resultados sugerem que a situação de pandemia pode ser considerada um determinante que afeta diferentes dimensões da vida dos adolescentes.

The main purpose of this study was to evaluate the effectiveness of a brief intervention and a preventive orientation on the use of alcohol and other drugs directed towards adolescents. Ninety nine youths who sought medical assistance in an out patient service specialized in adolescents were classified, according to their level of consumption of substances, into users during the last month (UM) or non users during the last month (NUM). Each of these was divided into four groups: a control group of users in the last month (COUM), a control group of non users in the last month (CONUM), a Brief Intervention group (BI--in case they were regular users) and a Preventive Orientation group (PO--in case they were non users in the last month). The preventive orientation lasted 2-3 minutes and the brief intervention took about 20 minutes, both followed a structured schedule. All participants were followed-up and evaluated for a 6 months period. In the 6-month follow-up, a significant increase in cannabis, alcohol and tobacco consumption, as well as in the intensity of related-problems, was observed in the CONUM group. The increase of alcohol and tobacco consumption observed in the PO group had a significantly lesser frequency and lower intensity than in the CONUM group. Moreover, no increase in cannabis consumption was observed in this group. The BI group showed a significant reduction in the number of users during the last month with respect to most substances, as well as in relation to substance-related problems. Our results confirm that a single brief intervention session is effective in reducing consumption of psychoactive substances in adolescents. Although influence of other factors could not be discarded, preventive orientation reduced the increase of cannabis consumption but increased use of tobacco and alcohol. Further and more in depth studies are required to evaluate the usefulness of preventive programs on alcohol and other drug consumption, in order to bring to light more effective and comprehensive approaches.

This study evaluated the profile of public and private high school students (N = 254, M_age = 15.1, SD = 1.3) in the city of São Paulo in relation to their Internet use patterns and quality of life. We used the Internet Addiction Test and the Pediatric Quality of Life Inventory. About 70% of the students had moderate Internet addiction. Those students from public school showed higher scores of Internet addiction (p < 0.001) than students from private schools. Regarding the quality of life, those from private school showed better scores regarding academic performance (p < 0.01) and worse scores in social aspect (p < 0.05). The data showed a strong association between Internet addiction and poor levels of quality of life, as observed in studies from other countries.

Regardless of the amount of time connected to the internet, the World Wide Web Foundation ranked Brazil third place, in which Brazilian people spent more than nine hours daily online (^{World Wide Web Foundation, 2019}). On this report, the population also spent more than 3.3 hours per day connected to social networks, only behind the Philippines. Concerning adolescents, Brazil ranks second in time of internet connection outside of school hours (3.1 hours per day), and almost 30% of the students spend more than six hours a day connected, according to the Organization for Economic Co-operation and Development (²⁰¹⁷).
