ABSTRACT
Resumo Objetivou-se investigar a associação entre o tempo de uso excessivo de diferentes telas, a qualidade da dieta em adolescentes e características do entorno escolar. Adolescentes de 30 escolas estaduais de Curitiba/PR relataram tempo de tela: televisão, videogame e portáteis. A qualidade da dieta foi avaliada pela frequência de consumo de alimentos. A renda do entorno escolar foi obtida do Censo. O ambiente construído para atividade física investigado por observação sistemática do entorno escolar. A regressão de Poisson multinível foi empregada para estimar associações com as variáveis de exposição. Entre 1.200 adolescentes, 50,9% do sexo masculino, 74,4% tiveram tempo excessivo de tela. O tempo excessivo de TV (56,5%) esteve associado à pior qualidade da alimentação. O tempo excessivo de videogame (22,0%) foi menor no sexo feminino (RP 0,25; IC95% 0,18;0,36), associado à pior qualidade da alimentação, à menor renda do entorno escolar, e à pior classificação do ambiente construído para atividade física. O tempo excessivo de telas portáteis (53,2%) apresentou tendência de aumento com a renda do entorno escolar. O uso excessivo de TV e telas portáteis foi amplamente praticado por adolescentes, com diferentes variáveis demográficas e contextuais associadas de acordo com o tipo de dispositivo utilizado.
Abstract Adolescents from 30 state schools in Curitiba, State of Paraná, reported total screen time, namely television, video games and laptops. Diet quality was assessed by the frequency of food consumption. The income of the school environment was taken from the Census. The built environment for physical activity was investigated by systematic observation of the school surroundings. Multilevel Poisson Regression was used to estimate associations with the exposure variables. Among 1,200 adolescents, 50.9% being male, and 74.4% were found to be exposed to excessive screen time. Excessive TV screen time (56.5%) was associated with poor diet quality. Excessive video game time (22.0%) was lower among females (PR 0.25; 95%CI 0.18;0.36), associated with poor diet quality, lower school environment income, and the worst classification of the built environment for physical activity. Excessive use of portable screens (53.2%) tended to increase with the income of the school environment. Excessive use of TV and laptops was widespread among adolescents, with different demographic and contextual variables associated according to the type of device used.
ABSTRACT
The correlation between inattention and hyperactivity symptoms/behavior manifestations and screen time was evaluated among Brazilian children and adolescents (7-18 years old) who were socially isolated due to the COVID-19 pandemic. A total of 517 legal guardians completed questionnaires about electronic media use (MAF-P) and emotional/behavioral problems (CBCL/6-18). The results showed that texting was correlated to less inattention/hyperactivity symptoms; listening to music, the use of social media and electronics for school purposes were negatively correlated to attention problems and inattention/hyperactivity symptoms and playing videos games and online videos were associated to more attention problems and inattention/hyperactivity symptoms. The results contribute to the understanding of the relationship between inattention/hyperactivity symptoms and screen time in a sample of Brazilian children and adolescents during the pandemic.
Se evaluó la correlación entre síntomas/manifestaciones conductuales de inatención e hiperactividad y tiempo de uso de medios electrónicos entre niños y adolescentes brasileños (7-18 años) en aislamiento social por la pandemia de COVID-19. Los participantes fueron 517 tutores que completaron inventarios de uso de medios (MAF-P) y problemas emocionales/conductuales (CBCL/6-18), entre junio y agosto de 2020. Los resultados indican que más tiempo dedicado a la comunicación de mensajes se correlacionó con menos informes de síntomas de inatención/hiperactividad; Escuchar música durante más tiempo, usar redes sociales y dispositivos electrónicos para la escuela/el trabajo se asoció con menos síntomas inatención/hiperactividad y problemas de atención. Finalmente, jugar más videojuegos y ver videos en línea se asoció con más síntomas de falta de atención/hiperactividad y problemas de atención. Los resultados contribuyen a comprender que existen asociaciones entre la frecuencia de síntomas de inatención/hiperactividad y el tiempo de uso de medios electrónicos en una muestra de niños y adolescentes brasileños durante la pandemia.
Avaliou-se a correlação entre sintomas/manifestações comportamentais de desatenção e hiperatividade e tempo de uso de mídias eletrônicas entre crianças e adolescentes (7-18 anos) brasileiras em isolamento social devido a pandemia da COVID-19. Participaram 517 responsáveis que preencheram inventários de uso de mídias (MAF-P) e de problemas emocionais/comportamentais (CBCL/6-18), entre junho-agosto de 2020. Resultados indicam que mais tempo em comunicação por mensagens correlacionou-se a menos relatos de sintomas de desatenção/hiperatividade; já mais tempo ouvindo música, usando redes sociais e eletrônicos para escola/trabalho associaram-se com menor número de sintomas de desatenção/hiperatividade e de problemas atencionais. Por fim, maior em videogames e assistindo vídeos online associaram-se a mais sintomas de desatenção/hiperatividade e problemas atencionais. Os resultados contribuem para entender que existem associações entre frequência de sintomas de desatenção/hiperatividade e tempo de uso de mídias eletrônicas em uma amostra de crianças e adolescentes brasileiros durante a pandemia.

Abstract Background: Headache represents the most common neurologic symptom in children. In this study, we investigated the relationship between watching television, listening to music with headphones, smartphone, tablet, and computer use, and primary headaches in children. We aimed to determine whether primary headache in children is associated with excessive use of digital display devices and headphones and whether reducing the use of digital display devices and headphones affects primary headache. Methods: The study included 69 children with primary headaches and 64 with no headaches as a control group. All subjects were evaluated for demographic and headache characteristics and the use of digital display devices and headphones. Our recommendation for patients and families was to decrease the use of digital display devices and headphones, and the headache burden was re-evaluated after one month. Results: Headache frequency was more common in patients who watched television and used smartphones or tablets for more than 6 hours per day. Using a smartphone or tablet for more than 3 hours daily was more common in the study group than the control group. Headache frequency decreased in all patients one month after the digital imaging device and headphones were restricted. Conclusions: Watching television and using a smartphone or tablet strongly associates with primary headaches during childhood.
Resumen Introducción: La cefalea representa el síntoma neurológico más común en los niños. En este estudio se investigó la relación entre ver televisión, escuchar música con auriculares, el uso del teléfono inteligente o tableta y computadora y el dolor de cabeza primario en niños. Nuestro objetivo fue determinar la asociación entre la cefalea primaria en niños y el uso excesivo de dispositivos de visualización digital y auriculares, y el efecto de la disminución del uso de dispositivos de visualización digital y auriculares sobre la cefalea primaria. Métodos: El estudio incluyó a 69 niños con cefaleas primarias y 64 niños sin cefaleas como grupo control. Se evaluaron las características demográficas y de dolor de cabeza y uso de dispositivos de visualización digital y auriculares de los participantes. Se aconsejó a los pacientes y familiares que disminuyeran el uso del dispositivo de pantalla digital y los auriculares y se volvió a evaluar la carga de dolor de cabeza después de 1 mes. Resultados: La frecuencia de la cefalea fue más frecuente en los pacientes que veían televisión y utilizaban un teléfono inteligente o una tableta más de 6 horas al día. El uso de más de 3 horas al día fue más común en el grupo de estudio que en el grupo control. La frecuencia del dolor de cabeza disminuyó en todos los pacientes 1 mes después de la restricción del dispositivo de imagen digital y los auriculares. Conclusiones: Ver la televisión y el uso de un teléfono inteligente o tableta se asocian estrechamente con el dolor de cabeza primario en la infancia.
ABSTRACT
Adolescents (children aged 11-19 years) are at the greatest peril when it comes to use of smart gadgets. These gadgets are essential for literacy and development, but also have the potential to cause addiction and other unwanted effects. Finding the right balance is the key. Thus, there is a considerable need to devise, enlist and convey to parents, various hacks and heuristics that can be used by them to optimize the use of smart gadgets by their teenager children. This communication should prove helpful for all health care professionals who are directly or indirectly involved in adolescent health care.
ABSTRACT
Purpose: Increased screen time has been a major concern among the students who have adopted the online curriculum amid the pandemic. The study was conducted to shed light on the changing trends of symptoms pertaining to dry eye disease and digital eyestrain due to the online curriculum and its negative implications on the ocular health of students. Methods: A cross?sectional study was conducted among students of Manipal Academy of Higher Education who are currently following the E?learning curriculum amid the COVID?19 pandemic the participants were surveyed using a pre?validated structured questionnaire. Results: The mean age of study participants was 23.33 ± 4.604 years. In total, 97.9% (321/352) of the respondents experienced at least three symptoms associated with the usage of digital devices. 88.1% of the participants were exposed to an average screen time of more than 4 hours per day. An increased number of hours of digital device usage was found to be associated with higher total symptom scores (P = 0.04). The total symptom scores were found to be considerably higher for those with continuous contact with the screen (P = 0.02). Headache (69.9%, n = 246) is the most commonly reported symptom followed by neck pain (65.3%, n = 230), tearing (44.6%, n = 157), eye pain (40.9%, n = 144), and burning sensation (40.1%, n = 141). Conclusion: This study highlights a tremendous increase in the prevalence of symptoms related to dry eye and digital eyestrain among students attending online classes during the COVID?19 pandemic. Eye care professionals need to be aware of this emerging public health threat and the appropriate measures for its prevention
ABSTRACT
Purpose: Dry eye is a multifactorial disease of the ocular surface. It showed an increased incidence during the pandemic situation, which may be due to long hours of exposure to electronic gadgets. We aimed to find the prevalence of dry eye disease among medical students during the coronavirus disease 2019 (COVID?19) pandemic and pre?pandemic periods. Methods: This was a cross?sectional study conducted in a tertiary care teaching institute. This was an institution?based, cross?sectional study conducted among medical students. A modified Ocular Surface Disease Index (OSDI) questionnaire was used to find the severity and prevalence of dry eye disease. Considering 95% confidence interval (CI) and prevalence as 50%, the calculated sample size was 271. Online responses were collected and entered in an Excel sheet. The Chi?square test, univariate and multivariate logistic regression were used for statistical analysis. Results: Data were collected from 271 medical students; the prevalence of dry eye disease was 41.5 and 55.19 during the pre?pandemic and pandemic periods, respectively. There was a significant rise in dry eye disease cases during the pandemic when compared to pre?pandemic period (P < 0.05). The odds of getting dry eye disease were 1.7 times more during the pandemic than pre?pandemic. Conclusion: The lockdown situation during the pandemic forced people to use electronic gadgets for work, recreation, and academics. Prolonged screen time predisposes to the development of dry eye disease
ABSTRACT
Background: Smartphone addiction among adolescents is an increasingly recognized problem worldwide. It affects the psychological well-being of an individual. Aim and objective: The current study aimed to assess smartphone addiction’s prevalence and its relation to depression among adolescents. Methods: This cross-sectional study was conducted among 400 school-going adolescents. Smartphone Addiction Scale - Short version (SAS-SV) and Patient Health Questionnaire (PHQ-9) were used to assess the prevalence of smartphone addiction and depression. Data were analyzed using Epi info software for windows (CDC, Atlanta). Statistical significance was set at p < 0.05. Results: The mean age of study participants was 14.4 years (SD=1.5 years). The prevalence of smartphone addiction was 23%, while depression was present among 45% of the study participants. Comparatively higher duration of smartphone use was significantly associated with smartphone addiction. Depression was significantly higher among smartphone addicts (77.2%) as compared to their counterparts (35.4%). Conclusion and Recommendation: The smartphone usage of adolescents, if not monitored, could lead to its addiction and thus increase the risk of depression among them. To prevent smartphone addiction, limiting children’s screen time is recommended. In this regard, parents can play a pivotal role by becoming responsible digital role models for their children.
ABSTRACT
Background: Continuous and long-term exposure to the screens of electronic devices, especially smartphones, cell phones, and tablets, is associated with poor quality of sleep. Aim and Objectives: The study was undertaken to correlate screen time exposure and the quality of sleep in undergraduate medical students and to find out the effects of increased screen time exposure on the health of students. Materials and Methods: The study was carried out on 200 undergraduate medical students at Smt. B. K. Shah Medical Institute and Research Centre, Piparia, Vadodara, Gujarat with the help of an online pre-validated questionnaire constructed on Google Form after obtaining ethical approval.

For the descriptive statistical part, means, standard deviations, and frequency tables were used. A Chi-square test was applied to detect the strength of the association. P < 0.05 was considered statistically significant. Results: The prevalence of increased screen time among the study population was found 79%. The prevalence of PSQI scores >5 observed in the present study was 73%. There was a significant association observed between increased screen time exposure and PSQI score >5. Conclusion: Increased screen time was significantly associated with poor sleep quality. The most common effect of increased screen time exposure among students found was a headache.
ABSTRACT
Comparar o tempo de exposição a telas de lactentes entre os períodos pré e durante a pandemia da COVID-19 e averiguar fatores relacionados a exposição de tela durante esse período. Responderam ao "Questionário tempo de exposição a telas", 63 responsáveis de lactentes, em dois períodos: pré e durante a pandemia COVID-19. Para a comparação entre os períodos, foi utilizado o teste de Wilcoxon Rank. Durante a pandemia da COVID-19, aumentou-se significativamente o tempo de telas, passando de mediana de 4 para 7 horas semanais, destacando-se a televisão como dispositivo mais utilizado. Observou-se a correlação entre idade do lactente e tempo de exposição a telas. Houve aumento do tempo de exposição a telas durante a pandemia da COVID-19 nos lactentes avaliados. O tempo total de telas apresentou uma correlação proporcional com a idade nos períodos avaliados, porém não se correlacionou com a realização de home-office dos responsáveis.
To compare the infants' time exposure to screens between pre- and during the COVID-19 pandemic and to investigate factors related to screen exposure during this period. The "Screen exposure time questionnaire" was answered by 63 caregivers of infants, in two periods: before and during the COVID-19 pandemic. For comparison between periods, the Wilcoxon Rank test was used. During the COVID-19 pandemic, infants' time exposure to screens increased significantly, from a median of 4 to 7 hours per week, with television being the most used device. A correlation was observed between infant age and time exposure to screens. There was an increase in infants' time exposure to screens during the COVID-19 pandemic. Total screen time showed a proportional correlation with age in the evaluated periods; however, it did not correlate with the home-office performance of those responsible.
ABSTRACT
The aims of the study were to verify the effect of an intervention on the stage of behavior change for TV viewing and to identify the possible mediating role of knowledge on screen time guidelines among Brazilian students. This study is a multicomponent school-based intervention conducted with 727 students (54.3% female, 13 years; 427 in the intervention group and 300 in the control group). The intervention was performed in 2017 with baseline and post-intervention assessments (over one academic year). Teacher training was carried out at the beginning of the intervention along with en-vironmental improvements, while educational curriculum such as the delivery of folders and posters were performed throughout the year. The stages of behavior change for TV viewing and knowledge of screen time guidelines were measured by a self-reported questionnaire and the structural equation modeling approach was performed. The intervention had no significant effects on stages of behavior change for TV (p = 0.744) nor did it result in significant changes on knowledge of screen time guide-lines (p = 0.741). While there was no mediation between knowledge of screen time guidelines and the effect of the intervention on stages of behavior change for TV (95%CI: -0.45;0.63), an associa-tion was found between knowledge of screen time guidelines and stages of behavior change for TV (p<0.001). In conclusion, intervention had no significant effect on the stages of behavior change for TV and no mediating effect was observed. However, enhancing awareness on screen time guidelines may positively impact the adolescent's intention to reduce TV time
Os objetivos do estudo foram verificar o efeito de uma intervenção nos estágios de mudança de comporta-mento para assistir TV e identificar o papel mediador do conhecimento sobre as recomendações de tempo de tela. A intervenção multicomponente, randomizada e controlada obteve a participação de 727 alunos em 2017 (54,3% meninas, 13 anos; 427 no grupo intervenção e 300 no grupo controle). A formação dos pro-fessores foi realizada no início da intervenção juntamente com as melhorias ambientais, enquanto as ações educativas foram realizadas ao longo do ano. Os estágios de mudança de comportamento para assistir TV e o conhecimento sobre as recomendações do tempo de tela foram mensurados por questionário auto reportado, pré e pós-intervenção (um ano letivo). Para análise dos dados foi realizada uma modelagem de equações estru-turais. Não houve efeito da intervenção nos estágios de mudança de comportamento para TV (p = 0,744) e também não houve mudanças significativas no conhecimento dos estudantes sobre as recomendações do tempo de tela (p = 0,741). Embora não tenha havido mediação entre conhecimento das recomendações do tempo de tela e o efeito da intervenção nos estágios de mudança de comportamento para TV (IC95%: -0,45;0,63), foi encontrada associação entre o conhecimento das recomendações e os estágios de mudança de comportamento para TV (p < 0,001). Conclui-se que a intervenção não teve efeito significativo nos estágios de mudança de comportamento para TV e efeito mediador. No entanto, aumentar a conscientização sobre as recomendações de tempo de tela pode impactar positivamente na intenção do adolescente de reduzir o tempo de TV
ABSTRACT
The adverse effects of prolonged screen exposure on infants, children, and adolescents have been confirmed by a growing number of studies.Without early detection and intervention, these adverse effects may persist throughout a child′s growth and development.The period of preschool is a critical time for children′s neurological development and the adverse neurological damage caused by heavy screen exposure during this period should be taken seriously.This paper introduces the current situation of children′s electronic screen use in China and abroad, the definition of screen dependency disorders, focuses on the specific effects of prolonged screen dependency on the neurological development of preschool children and its possible mechanisms, and discusses early intervention measures with evidence-based medicine, aiming to provide a reference for the scientific use of electronic screens in preschool children.
ABSTRACT
A adolescência é um período marcado por alterações neuroendócrinas que influenciam o desenvolvimento do cérebro e o comportamento. Adolescentes apresentam chances aumentadas de adotar comportamentos de risco em seu estilo de vida, dentre eles o comportamento sedentário. Nesse sentido, estudos de intervenção têm buscado desenvolver estratégias eficientes para estimular adolescentes a adotarem um estilo de vida saudável. No entanto, embora ações promissoras possam ser identificadas na literatura, o real mecanismo que atua na regulação do comportamento em adolescentes parece estar associado a uma neurotrofina chamada de Fator Neurotrófico Derivado do Cérebro (BDNF), e estudar como os comportamentos de risco influenciam na sua secreção são de grande relevância para desenvolver intervenções mais efetivas. Sendo assim, o objetivo da presente tese é descrever a fundamentação teórica para o planejamento de uma intervenção multicomponente baseada na escola com ações combinadas para a promoção da atividade física, redução do comportamento sedentário e educação alimentar e nutricional, e as possíveis consequências para o desempenho cognitivo e saúde de adolescentes. A metodologia está descrita em formato de coletânea de artigos e foi dividida em quatro etapas. A primeira etapa descreve uma revisão sistemática que foi desenvolvida durante os estudos de fundamentação teórica para o planejamento da intervenção do Programa Atitude, Movimento e Escolhas para uma vida saudável (Programa AME), em que foi possível identificar a necessidade de implementar uma etapa específica de formação dos professores de educação física. Na segunda etapa foi detalhada a metodologia de uma revisão sistemática que tem como objetivo de investigar a associação entre comportamento sedentário e BDNF em adolescentes. O protocolo metodológico da revisão foi registrado no Registro Internacional Prospectivo de Revisões Sistemáticas (PROSPERO) sob o identificador CRD42023392246 e segue as diretrizes dos Principais Itens para relatar Revisões Sistemáticas e Meta-análises (PRISMA). A etapa três apresenta essa revisão sistemática concluída, com todos os resultados das buscas e análise das informações extraídas dos artigos incluídos. A quarta etapa trata-se de um estudo de justificativa e fundamentação teórica para os métodos abordados no eixo de comportamento sedentário da intervenção do Programa AME, a qual foi registrada na plataforma do Registro Brasileiro de Ensaios Clínicos sob o número RBR-86xv46. Pode-se dizer que o Programa AME é uma proposta integrada, sustentável e de baixo custo, com grande potencial para produzir benefícios no estilo de vida, desempenho cognitivo e saúde de adolescentes. Por fim, os resultados desses estudos fortalecerão a prática baseada em evidências no âmbito de pesquisas voltadas para a promoção da saúde no contexto escolar (AU).
Adolescence is a period marked by several neuroendocrine changes that influence brain development and behavior. Adolescents are more likely to adopt risky behaviors in their lifestyle, including sedentary behavior. In this sense, intervention studies have sought to develop efficient strategies to encourage adolescents to adopt a healthy lifestyle. However, although promising actions can be identified in the literature, the real mechanism that acts in the regulation of behavior in adolescents seems to be associated with the neurotrophin Brain-Derived Neurotrophic Factor (BDNF), and studying how risk behaviors influence its secretion are of great relevance to develop more effective interventions. Therefore, the objective of this thesis is to describe the theoretical foundation to the planning of a school-based multicomponent intervention with combined actions to promote physical activity, reduction of sedentary behavior and food and nutrition education, and the possible consequences for cognitive performance and adolescent health. The methodology of this thesis is described in the format of a collection of articles and was divided into four stages. The first stage describes a systematic review that was developed during the theoretical foundation studies for planning the intervention of the Attitude, Movement and Choices for a Healthy Life Program (AME Program), and it was possible to identify the need to implement a specific training stage for physical education teachers. In the second stage, was detailed the methodology of a systematic review that will be developed with the objective of investigating the association between sedentary behavior and BDNF in adolescents. The methodological protocol for the review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) under the identifier CRD42023392246 and follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The third stage presents this completed systematic review, with all search results and analysis of information extracted from the included articles. The fourth step is a study of rationale and theoretical foundation for the methods addressed in the sedentary behavior axis of the AME Program intervention, which was registered on the Brazilian Registry of Clinical Trials platform under the number RBR-86xv46. It can be said that the AME Program is an integrated, sustainable and low-cost proposal, with great potential to produce benefits in lifestyle, cognitive performance and health of adolescents. Finally, the results of these studies will strengthen evidence-based practice in research aimed at promoting health in the school context (AU).

ABSTRACT Objective: To identify the impact of the Covid-19 pandemic on the use of digital screens in early childhood, from the perspective of mothers and education professionals. Method: Qualitative study, based on Bronfenbrenner's Bioecological Theory. Nine mothers of children under three years of age, enrolled in daycare centers in a municipality in the state of Paraíba, Brazil, and six education professionals who worked in these daycare centers participated. The data were collected between July and October 2021 via virtual interviews and analyzed according to inductive thematic analysis. Results: The restrictions imposed by the pandemic made screens the only available resource for children's educational activities, interaction, leisure, and distraction, causing an exponential increase in the time they spent in front of screens. Conclusion: The pandemic had a direct impact on the use of digital screens in early childhood, increasing the child's exposure time, according to parents and education professionals.

Conclusão: A pandemia repercutiu diretamente no uso de telas digitais na primeiríssima infância, impactando no aumento do tempo de exposição da criança, segundo os pais e profissionais da educação.
ABSTRACT
Introdução: O cotidiano está cada vez mais permeado pela tecnologia. A evolução das plataformas de mídia, além de otimizar a informação, tem um papel importante na aproximação das pessoas, sobretudo em contextos de isolamento social, como o vivido na pandemia da Covid-19. Pais, professores, pesquisadores e formuladores de políticas relatam preocupação com possíveis efeitos desfavoráveis do uso excessivo de telas, em especial, na saúde mental das pessoas. Como os indivíduos podem responder diferentemente a exposição às telas em cada etapa do desenvolvimento, este estudo tem o objetivo de investigar as associações entre tempo de tela e a saúde mental dos indivíduos nas diferentes fases do ciclo vital. Desde crianças, nos adolescentes, nos adultos até os idosos serão avaliados quanto aos potenciais efeitos da exposição às telas. Método: A investigação foi realizada por meio de quatro revisões sistemáticas da literatura. Uma pergunta PICO foi estabelecida, em conformidade com o Protocolo PRISMA, bem como foi realizado registro da revisão no PROSPERO e avaliado risco de viés por instrumentos padronizados. As bases de dados Scopus, Pubmed e PsycInfo foram escolhidas para busca do tema e os descritores foram escolhidos conforme a faixa etária e de acordo com o significado no MESH. Como o uso das telas tem se modificado ao longo dos anos, optamos por incluir apenas estudos dos últimos 10 anos. Amostras com as idades pertinentes a cada fase do ciclo vital, sem diagnóstico mencionado de problemas de saúde mental prévio, que utilizaram escalas para avaliar os diversos aspectos de saúde mental e que apresentaram associações diretas de tempo de tela com desfechos de saúde mental foram selecionadas. A perspectiva ao longo da vida foi norteadora para a comparabilidade e análise dos resultados. Resultados: Dentre os desfechos em saúde mental, depressão e ansiedade foram os que apareceram em todas as quatro fases investigadas do ciclo vital. As respostas à influência do tempo de tela na saúde mental foram diferentes em cada fase do ciclo vital. O uso de telas apontou fatores particulares com adolescentes apresentando mais autoagressão relacionada ao uso de telas; adultos mais estresse, idosos mais sofrimento psicológico e crianças apresentaram mais problemas de comportamentos. O conteúdo das telas demonstrou exercer impacto importante na saúde mental e não somente a contabilização do tempo. Conclusão: O indicador "tempo de tela" pode não ser o mais apropriado para as investigações dos efeitos da exposição a dispositivos de tela em resultados de saúde mental. Pesquisas futuras devem considerar a ideia de que nos encontramos irremediavelmente envolvidos pelas telas e resta descobrir maneiras de se conviver de forma saudável com essa nova realidade.
Introduction: Everyday life is increasingly permeated by technology. The evolution of media platforms, in addition to optimizing information, plays an important role in bringing people together, especially in contexts of social isolation, such as that experienced during the Covid-19 pandemic. Parents, teachers, researchers and policy makers report concern about possible unfavorable effects of excessive screen use, especially on people's mental health. As individuals may respond differently to exposure to screens at each stage of development, this study aims to investigate the associations between screen time and the mental health of individuals at different stages of the life cycle. Children, teenagers, adults and the elderly will be assessed regarding the potential effects of exposure to screens. Method: The investigation was carried out through four systematic literature reviews. A PICO question was established, in accordance with the PRISMA Protocol, and the review was registered in PROSPERO and risk of bias was assessed using standardized instruments. The Scopus, Pubmed and PsycInfo databases were chosen to search for the topic and the descriptors were chosen according to the age group and according to the meaning in MESH. As the use of screens has changed over the years, we chose to only include studies from the last 10 years. Samples with ages relevant to each phase of the life cycle, without a previous diagnosis of mental health problems, which used scales to assess the different aspects of mental health and which presented direct associations between screen time and mental health outcomes were selected. The lifelong perspective was a guide for comparability and analysis of results. Results: Among the mental health outcomes, depression and anxiety were those that appeared in all four phases of the life cycle investigated. Responses to the influence of screen time on mental health were different at each stage of the life cycle. The use of screens highlighted particular factors with adolescents presenting more self-harm related to the use of screens; adults more stress, elderly people more psychological suffering and children showed more behavioral problems. The content of screens has been shown to have an important impact on mental health, not just time tracking. Conclusion: The "screen time" indicator may not be the most appropriate for investigations of the effects of exposure to screen devices on mental health outcomes. Future research should consider the idea that we find ourselves irremediably involved in screens and that it remains to discover ways to live in a healthy way with this new reality.

Abstract Most children grow up in homes with easy access to multiple screens. Screen use by children between the ages of 0 to 5 has become a worldwide preoccupation. In the present narrative review, we examine child and parent screen use and its contribution to physical, cognitive, and social developmental outcomes. As research has mostly focused on the adverse consequences of screen media, we aim to depict both the negative and the positive influences of screen usage. To provide a more nuanced portrait of the potential benefits and harms of screen use, we examine how consequences of media use vary according to the content of media (ex., educational, violent), context (ex., using screens during mealtimes), and the nature (ex., passive vs active use) of child screen use. Our review supports existing screen time guidelines and recommendations and suggests that media content, the context of use, and the nature of child use, as well as the parent's own screen use, be considered clinically. Future research should seek to clarify how these dimensions jointly contribute to child screen use profiles and associated consequences. Finally, child sex, behavioral/temperamental difficulties, and family adversity appear to contribute to child screen use and its consequences and should be considered in future research. Suggestions for harm-reduction approaches are discussed.
ABSTRACT
As Doenças Crônicas não Transmissíveis representam um problema de saúde pública a nível mundial, e são resultantes da combinação de distintos fatores de risco, a exemplo a prática insuficiente de atividade física e o uso excessivo de dispositivos eletrônicos. Identificar a frequência da prática de atividade física e do uso de dispositivos eletrônicos e televisão entre estudantes universitários. Trata-se de um estudo transversal com abordagem quantitativa realizado com 87 universitários de uma IES privada do Distrito Federal no segundo semestre de 2020. A coleta de dados foi realizada mediante questionário eletrônico estruturado. Para a análise dos dados foi utilizado a estatística descritiva através do software Statistical Package for Social Sciences (SPSS) versão 21.0. Observou-se que 63 (72,4%) estudantes relataram praticar algum tipo de atividade física nos últimos três meses. No que diz respeito a frequência da prática de atividade física, 53 (60,9%) discentes relataram praticar por pelo menos uma vez na semana, e 21 (24,1%) informaram a prática de 3 a 4 dias por semana. Quanto ao uso de dispositivos eletrônicos, observou-se que 80 (92,0%) discentes referiram utilizá-los em seu tempo livre, o tempo de uso mais relatado foi de 2-3 horas. Observou-se uma frequência elevada da utilização de dispositivos eletrônicos e da prática insuficiente de atividade física entre universitários durante a pandemia de COVID-19. Sendo assim, é crucial o estabelecimento de intervenções de promoção para adoção de hábitos de vida saudáveis para este grupo.
Chronic Noncommunicable Diseases represent a public health problem worldwide and are the result of a combination of different risk factors such as insufficient physical activity and excessive use of electronic devices. To identify the frequency of physical activity and the use of electronic devices and television among college students. This is a cross-sectional study with a quantitative approach carried out with 87 university students from a private Higher Education Institution in the Federal District during the second half of 2020. Data collection was performed using a structured electronic questionnaire. Descriptive statistics were used for data analysis using the Statistical Package for Social Sciences (SPSS) version 21.0 software. It was observed that 63 (72.4%) students reported practicing some type of physical activity in the last three months. Concerning the frequency of physical activity, 53 (60.9%) students reported practicing at least once a week, and 21 (24.1%) reported practicing 3 to 4 days a week. As for the use of electronic devices, it was observed that 80 (92.0%) students reported using them in their free time, the most reported time of use was 2-3 hours. There was a high frequency of use of electronic devices and insufficient practice of physical activity among university students during the COVID-19 pandemic. Therefore, it is crucial to establish interventions to promote the adoption of healthy lifestyle habits for this group.
ABSTRACT
ABSTRACT Objective: To identify and summarize the possible associations between screen time and low back pain in children and adolescents. Data source: Systematic searches were performed in five electronic databases (Lilacs, Scielo, Scopus, PubMed and Web of Science) on 01/25/2021, complemented by manual searches in reference lists and on Google Scholar, looking for original scientific articles that included Brazilian observational studies; whose samples had children and/or adolescents aged between 6 and 19 years, without specific clinical conditions, and that presented analyses of associations between indicators of screen time and nonspecific low back pain, based on regression models. Data synthesis: Nine cross-sectional studies whose samples had adolescents were included. Of the 18 analyses identified, nine reported risk relationships between the variables of interest. More specifically, risk associations were found in two studies that evaluated adolescents exposed to at least three hours using cell phone or tablet, and watching television per day. Also, instruments, cut-off points adopted, and screen equipment evaluated were diverse. Conclusions: Even though most of the risk associations were borderline from the statistical point of view, we found a higher frequency of risk associations between screen time and non-specific low back pain in adolescents exposed to screen time for at least three hours a day. In addition, further longitudinal studies with samples composed of children should be conducted across the country.
Resumo Objetivo: Identificar e sumarizar os dados sobre as possíveis associações entre o tempo de tela e a dor lombar em crianças e adolescentes. Fontes de dados: Buscas sistemáticas em cinco bases de dados eletrônicas (Lilacs, Scielo, Scopus, Pubmed e Web of Science), no dia 25/01/2021, complementadas por buscas manuais em listas de referências e no site Google Acadêmico, procurando por artigos científicos originais que comunicaram estudos observacionais brasileiros que envolveram amostras de crianças e/ou adolescentes entre 6 e 19 anos de idade, sem condições clínicas específicas e que apresentassem análises de associações entre indicadores do tempo de tela e dor lombar não específica, baseadas em modelos de regressão. Síntese dos dados: Nove estudos transversais foram incluídos, envolvendo amostras de adolescentes. Das 18 análises identificadas, 9 mostraram relações de risco entre as variáveis de interesse. Mais especificamente, verificaram-se associações de risco em dois estudos que avaliaram adolescentes expostos a, pelo menos, três horas diárias de celular, tablete e televisão. Também se observou diversidade entre instrumentos, pontos de corte adotados e equipamentos de tela avaliados. Conclusões: Mesmo que a maior parte das associações de risco tenha sido limítrofe, do ponto de vista estatístico, a presente síntese apresentou maior frequência de associações de risco entre o tempo de tela e a dor lombar não específica em adolescentes expostos ao tempo de tela por, pelo menos, três horas diárias. Complementarmente, recomenda-se que sejam conduzidos no país estudos longitudinais, com o envolvimento de crianças nas amostras.
ABSTRACT
Abstract Objective: To identify and map families' time of exposure to screens during the COVID-19 pandemic and to associate it with the frequency of children's food consumption. Methods: This is a cross-sectional study carried out with parents or guardians of children aged between 2 and 9 years through an online questionnaire. The participants answered questions about socioeconomic data, family's screen habits, and children's food consumption. Results: A total of 517 parents or guardians participated in the research. Children's median age when first exposed to screens was 6 months (interquartile range: 1-12 months). The average number of hours that children and guardians/parents were exposed to electronic devices was 3.9±2.3 and 9.0±2.9 respectively. As for food consumption, 60.9% of the guardians/parents and 54.3% of the children had the habit of having meals in front of screens. In addition, the consumption of snacks outside mealtimes, while using screens, was frequent in both groups. Conclusions: Children aged 2 to 9 years are excessively exposed to screens and the consumption of meals or snacks while using the devices is frequent. Considering the current demands of the pandemic, the necessity of using electronic devices is understandable. However, the authors emphasize the importance to educate families regarding limiting the use of screens, especially during meals, and monitoring the content of activities with electronic devices, as this exposure can influence food consumption and affect children's nutritional status and health.
RESUMO Objetivo: Identificar e mapear o tempo de exposição das famílias às telas durante a pandemia de COVID-19 e associá-lo com a frequência de consumo alimentar das crianças. Métodos: Trata-se de um estudo transversal, realizado com pais ou responsáveis de crianças de dois a nove anos de idade por meio de um questionário online. Participantes responderam a perguntas sobre dados socioeconômicos, hábitos familiares de uso de telas e consumo alimentar das crianças. Resultados: Participaram da pesquisa 517 pais ou responsáveis. A mediana de idade em que as crianças foram expostas pela primeira vez às telas foi de seis meses (intervalo interquartil: 1-12 meses). A média de horas durante as quais as crianças e os responsáveis ficavam expostos aos aparelhos eletrônicos foi de 3,9±2,3 e 9,0±2,9, respectivamente. Sobre o consumo de alimentos, 60,9% dos responsáveis e 54,3% das crianças tinham o hábito de realizar refeições em frente às telas. Além disso, o consumo de petiscos fora do horário das refeições, durante o uso de telas, foi frequente em ambos os grupos. Conclusões: Crianças de dois a nove anos estão expostas excessivamente às telas e o consumo de refeições ou petiscos durante o uso dos aparelhos é frequente. Diante das demandas atuais da pandemia, entende-se a importância do uso dos eletrônicos, porém reforça-se a necessidade de educar as famílias em relação à importância de limitar o uso de telas, especialmente durante as refeições, e de monitorar o conteúdo das atividades com telas, pois essa exposição pode influenciar a alimentação e repercutir no estado nutricional e na saúde das crianças.
ABSTRACT
RESUMO Objetivo Identificar as alterações oculares em crianças e adolescentes secundárias ao fator do isolamento social e ao consequente aumento do uso de telas. Métodos Estudo observacional, descritivo e analítico, do tipo transversal realizado no período de julho a agosto de 2021, por meio da aplicação de questionários. Resultados Apresentaram cefaleia associada ao uso excessivo de tela 26,51% dos estudantes e 38,8% relataram suspeita de insuficiência de convergência. Em relação ao questionário de olho seco, 18,8% foram sintomáticos e 7,5% sintomáticos de difícil manejo. O computador foi o dispositivo mais utilizado em atividades escolares (71,5%), e, em segundo lugar, esteve o celular (66,3%). Casos sintomáticos de olho seco foram mais relatados em participantes que não faziam uso de computador (36,4%). Não foi possível identificar relação entre insuficiência de convergência e tempo de uso de dispositivos. Em relação ao olho seco, aqueles que passaram mais tempo em frente a tela relataram maior porcentagem de sintomas de difícil manejo (42,9%). Conclusão Foram mais prevalentes olho seco e sintomas de insuficiência de convergência na população estudada.
ABSTRACT Objective To identify eye conditions associated to social distancing and related increase in screen time exposure on children and teenagers. Methods Observational, descriptive and analytical study, with a cross-section design, carried out between July and August 2021, by questionnaire survey. Results Headaches related to excessive screen time exposure were reported by 26.51% of the students surveyed, while 38.8% reported suspect convergence insufficiency. Regarding the questionnaire about dry eye, 18.8% were symptomatic and 7.5% reported hard-to-manage symptoms. Computers were the devices most used for schoolwork (71.5%), followed by cellphones on second place (66.3%). Symptomatic cases of dry eye were mostly reported by participants that did not make use of computers (36.4%). It was not possible to establish a connection between convergence insufficiency and device usage time. Those participants that reported more screen time exposure also reported an increased percentage of hard-to-manage symptoms (42.9%), regarding dry eye. Conclusion Dry eye and convergence insufficiency symptoms were more prevalent in the surveyed population.
ABSTRACT
Desde la década de los 90 debido al aumento en el consumo de material audiovisual y particularmente desde el inicio del confinamiento por la pandemia de COVID-19, la humanidad ha estado más expuesta al uso de pantallas, siendo los niños una población vulnerable al estímulo ambiental debido a que están atravesando períodos críticos importantes en su desarrollo. Se realizó una búsqueda de la literatura en PubMed, Google Scholar y Lilacs. Aplicando los criterios de exclusión e inclusión se obtuvieron 53 referencias de las cuales se desarrolló la revisión. Se encontró que la excesiva exposición a pantallas es perjudicial para los niños al producir alteraciones del lenguaje, la sociabilidad, ciclo sueño-vigilia, el sistema límbico, la conducta y el sistema mesolímbico dopaminérgico; los cuales pueden afectar su desarrollo normal, dependiendo principalmente de la edad al momento de la exposición, del tiempo y si hay acompañamiento o no.
Since the 1990s, due to the increase in the consumption of audiovisual material and particularly since the onset of the COVID-19 pandemic confinement, the population has been more exposed to development. A literature search was conducted in PubMed, Google Scholar and Lilacs. Applying the exclusion and inclusion criteria, 53 references were obtained, from which the review was developed. It was found that excessive exposure to screens is harmful to children as it produces alterations in language, sociability, sleep-wake cycle, limbic system, behavior and mesolimbic dopaminergic system; which can affect the normal development of a child, depending mainly on the age at the time of exposure, the time and whether there is accompaniment or not.
