ABSTRACT

Abstract BACKGROUND: Sitting time, screen time and low physical activity (PA) levels have been associated with several diseases and all-cause mortality. PA is related to better sleep quality and absence of daytime sleepiness, along with lower risks of obstructive syndrome apnea (OSA). However, studies on the relationship between sitting time, screen time and OSA are scarce in the literature. OBJECTIVE: To analyze associations between PA levels, sitting time, screen time and OSA among adults with suspected sleep disorder. DESIGN AND SETTING: Cross-sectional study conducted at Hospital Israelita Albert Einstein. METHODS: Data were collected from 369 adults with suspected sleep disorders who visited the hospital's neurophysiology clinic between August 2015 and January 2017. RESULTS: Correlations between hypopnea and PA indicators were demonstrated for total sitting time (0.123; P = 0.019) and total screen time (0.108; P = 0.038). There was also a correlation between latency for rapid-eye-movement sleep (REM_LAT) and total sitting time (0.103; P = 0.047) and a negative correlation between mean oxyhemoglobin saturation (SaO_Avg) and total PA time (-0.103; P = 0.048). There were no associations between PA parameters and apnea-hypopnea index. After adjusting for confounding factors (body mass index, age and gender), sitting time and screen time were not associated with OSA. CONCLUSION: After adjusting for anthropometric and clinical factors, excessive sitting time or screen time was not associated with OSA in adults suspected of sleep disorders. Age, gender, hypertension, body mass index and waist circumference were associated with OSA.

ABSTRACT

Abstract Objective: This longitudinal study aimed to verify possible changes in the time spent in sedentary activities occurring as screen-time, educational, cultural, social, and transportation domains in a sample of Brazilian adolescents between 2015 and 2017. Methods: It is a longitudinal prospective study with 586 adolescents from 12 to 15 years old at the Baseline (2015) enrolled in 14 public schools from Curitiba, Brazil. The Adolescent Sedentary Activity Questionnaire assessed the time spent in sedentary activities in five domains (recreational screen-time, educational, cultural, social, and transportation). A series of linear random effects regressions analyzed changes in the sedentary time between 2015 and 2017, with p < .05. Results: Overall, 323 adolescents dropped out of the study resulting in a retention rate of 44.9%. The overall sedentary time remained stable from 2015 to 2017 (-3.98 min/day, 95%CI: -15.39; 7.42). The screen-time decreased (-22.22 min/day, 95%CI: -30.30; -14.15), and educational (8.29 min/day, 95% CI: 3.52; 13.06), cultural (3.41 min/day, 95% CI: 0.66; 6.15) and social sedentary activities (8.20 min/day, 95% CI: 2.06; 14.34) increased from 2015 to 2017. Conclusion: Significant reductions in screen-time were evidenced along with increases in time spent on other sedentary activities of educational, cultural, and social nature.

ABSTRACT

ABSTRACT Over the past year and a half dental education has been conducted primarily online due to the SARS-CoV-2 pandemic. During the pandemic, we have spent many hours a day on our computers, mobile phones, and tablets to gather information and participate in online seminars and classrooms. Health consequences resulting from the overuse of these devices include carpal tunnel syndrome as well as computer vision syndrome (CVS). Computer vision syndrome, also known as digital eye strain, has several associated features such as eye burning, strained vision, dry eye, blurred vision, and associated neck and shoulder pain. Several predisposing factors have been linked with CVS, but often this problem gets ignored. The management of this syndrome is aimed at educating dentists on computer use, position, and the surrounding environment. Considering all this, we must ensure that we spend some time away from these devices every day to avoid any significant vision problems. The objective of preparing this manuscript was to provide a brief overview of the increased prevalence of computer vision syndrome and its associated features.

ABSTRACT

O objetivo deste estudo foi identificar e agrupar informações de aplicativos móveis voltados para a redução do comportamento sedentário (CS) existentes nas plataformas Google Play e iTunes. O levantamento ocorreu em agosto de 2020, utilizando-se os termos relacionados ao CS. Foram encontrados 196 aplicativos, sendo a maioria disponível apenas em língua inglesa e gratuitos. Em geral, os aplicativos podem ser divididos em quatro categorias: a) alertas/lembretes para quebra do CS; b) Restrição de aplicativos e bloqueio de tela; c) Monitoramento do CS e; d) Controle parental do tempo de tela. Funções estas que corroboram as recomendações de estudos sobre CS, que aconselham a inclusão de intervenções comportamentais, monitoramento do tempo de tela e o envolvimento da família (AU).


The objective of this study was to identify and group information from mobile applications aimed at reducing sedentary behavior (SB) existing on the Google Play and iTunes platforms. The survey took place in August 2020, using terms related to SB. Were found the 196 applications, most of which are available only in English and free. In general, applications can be divided into four categories: a) alerts/reminders for breaking the SB; b) Application restriction and screen lock; c) SB monitoring; and d) Parental control of screen time. These functions corroborate the recommendations of studies on SB, which recommend the inclusion of behavioral interventions, monitoring screen time, and family involvement (AU).

ABSTRACT

Objetivo: Evaluar la asociación entre los factores de riesgo en pacientes miopes en edad pediátrica. Métodos: Se realizó un estudio con diseño de casos y control para evaluar los factores de riesgo asociados a la miopía en los pacientes atendidos en la consulta del Servicio de Oftalmología Pediátrica del Instituto Cubano de Oftalmología "Ramón Pando Ferrer". La muestra estuvo conformada por 263 pacientes (123 casos y 140 controles) que cumplieron los criterios de inclusión y de exclusión. Las variables del estudio fueron la edad, el sexo, el color de la piel, la zona de procedencia, el bajo peso al nacer, la prematuridad, las madres fumadoras, el antecedente de familiares con defectos refractivos, las horas de exposición a las pantallas, las horas de exposición a la luz solar y la longitud axial. Resultados: Se encontró correlación entre el antecedente de familiares con defecto refractivo y la presencia de miopía (p = 0,009), y a su vez un riesgo de 1,9 de padecerla; más de 2 horas - pantallas se relaciona con pacientes miopes (p = 0,003) y duplica el riesgo. Más de 2 horas de luz solar fue más frecuente en los controles (p = 0,004) y es un factor de protección; las longitudes axiales fueron mayores en miopes (p = 0,000) y se correlacionó la exposición horas - pantallas con una mayor longitud axial. Conclusiones: Los antecedentes familiares de defectos refractivos aumentan 1,9 veces el riesgo de padecer miopía; la exposición a las pantallas por más de 2 horas al día lo duplica y la exposición a la luz solar por el mismo tiempo lo reduce a la mitad. La longitud axial es mayor en miopes y en los expuestos a las pantallas(AU)


Objective: Evaluate the association between risk factors in pediatric myopic patients. Methods: A case-control study was conducted to evaluate the risk factors associated to myopia in patients attending the Pediatric Ophthalmology Service at Ramón Pando Ferrer Cuban Institute of Ophthalmology. The sample was 263 patients (123 cases and 140 controls) who met the inclusion criteria. The study variables were age, sex, skin color, place of residence, low birth weight, prematurity, smoking mothers, a family history of refractive defects, screen time, sun exposure hours and axial length. Results: A correlation was found between a family history of refractive defects and the presence of myopia (p = 0.009), as well as a 1.9 risk of developing the disorder. More than two screen hours were associated to myopic patients (p = 0.003), doubling the risk. More than two sun exposure hours were more frequent among controls (p = 0.004) and constitute a protection factor. Axial lengths were greater among myopics (p = 0.000). Exposure and screen time were correlated with greater axial length. Conclusions: A family history of refractive defects increases the risk for myopia 1.9 times, exposure to screens for more than two hours per day doubles it, and the same number of sun exposure hours reduces it to half. Axial length is greater among myopics and screen exposed people(AU)

ABSTRACT

INTRODUCTION: Electronic devices have been used by increasingly younger people, leading researchers to investigate the impact of these technologies on the health of developing childrenOBJECTIVE: To investigate the impact of smartphone use on the postural control of Brazilian children 6 to 9 years oldMETHODS: This cross-sectional study was conducted with 278 children from public schools in Goiânia (Goiás, Brazil). The children were assessed in an orthostatic posture with the computerized baropodometry system in three conditions: eyes open, eyes closed, and using a free smartphone applicationRESULTS: The children were 8.36 years old on average, 82% of them were well-nourished, and had a daily mean screen time of 2 hours. The postural control analyses revealed that the children made greater postural adjustments with their eyes closed than with them open. When using the smartphone application, the postural adjustments were similar to those with eyes closed. In the stabilometry, the postural displacements made by the children behaved similarly to the static assessment only in total feet surface areaCONCLUSION: Smartphone use and absence of visual stimulus in the orthostatic position caused postural instability in children 6 to 9 years old. These findings can contribute to understanding the impact of technologies on children's development of balance in daily tasks


INTRODUÇÃO: O uso de dispositivos eletrônicos móveis tem alcançado usuários cada vez mais jovens e tem levado pesquisadores a investigar o impacto dessas tecnologias na saúde da criança em desenvolvimentoOBJETIVO: Investigar o impacto do uso do smartphone no controle postural de crianças brasileiras de 6 a 9 anos de idadeMÉTODO: Estudo transversal realizado com 278 crianças de escolas públicas de Goiânia (GO, Brasil). As crianças foram avaliadas na postura ortostática pelo sistema de baropodometria computadorizada em três condições: olhos abertos, olhos fechados e manuseando um aplicativo gratuito para smartphoneRESULTADOS: As crianças tinham idade média de 8,36 anos, sendo 82% de eutróficas e com tempo médio de tela de duas horas diárias. As análises do controle postural revelaram que as crianças apresentaram maiores ajustes posturais com os olhos fechados em comparação com os olhos abertos e ao usar o aplicativo do smartphone o ajuste postural foi semelhante ao encontrado com olhos fechados. Na estabilometria, os deslocamentos posturais realizados pelas crianças se comportaram de modo semelhante à avaliação estática apenas na área total da superfície dos pésCONCLUSÃO: O uso do smartphone e a ausência do estímulo visual na posição ortostática promoveram instabilidade postural nas crianças de 6 a 9 anos de idade. Estes achados podem contribuir para o conhecimento do impacto de tecnologias no desenvolvimento do equilíbrio de crianças em atividades diárias

ABSTRACT

Introducción. En estudios anteriores, el uso excesivo o la exposición temprana a pantallas se asoció con atención deficiente, falta de control de la conducta, retraso del lenguaje y déficit en la función ejecutiva. El objetivo de este estudio fue investigar la relación entre el tiempo de uso de pantallas y la regulación emocional, que afecta las relaciones sociales de los niños de 2 a 5 años.Población y métodos. Estudio descriptivo transversal en un hospital universitario del 1.º de enero al 1.º de marzo de 2018. Se incluyó a madres de niños sanos de 2 a 5 años con un uso de pantallas inferior a 1 hora o superior a 4 horas. A quienes aceptaron participar se les administró una encuesta estructurada y la Emotion Regulation Checklist para padres.Resultados. De los 240 niños participantes, 98 (el 40,8 %) tenían un uso de pantallas ≥ 4 horas. Ser cuidado por la madre, tener 12 meses o más durante la primera exposición y no estar acompañado por los padres al usarlas se asociaron con ≥ 4 horas de uso de pantallas (p = 0,002; p = 0,002; p = 0,012, respectivamente). La proporción de participantes con una puntuación alta de labilidad/negatividad (L/N) fue significativamente mayor entre los niños con ≥ 4 horas de uso de pantallas y que no estaban acompañados por sus padres al usarlas (p = 0,004; p = 0,033, respectivamente).Conclusiones. Este estudio determinó que un uso excesivo de pantallas se asocia con labilidad emocional durante esta etapa temprana de la infancia.


Introduction. Previous studies have found that excessive screen time or early screen exposure is associated with poor attention, lack of behavioral control, delayed language and deficit in executive functions. The aim of this study was to investigate the relationship between screen time and emotion regulation skills, which is one of the important life components affecting the social relations of children aged 2 to 5 years.Population and methods.This cross-sectional descriptive study was carried out in a university hospital between January 1, 2018 and March 1, 2018. Mothers of healthy children aged 2-5 years with a daily screen time of less than 1 hour or over 4 hours were included in the study. A structured survey and the Emotion Regulation Checklist for parents were applied to the mothers who agreed to participate.Results. Of 240 children participating in the study, 98 (40.8 %) had ≥4 hours of screen time. Caring by mother, age at first screen exposure 12 months and older, not co-viewing with parents were found to be associated with ≥ 4 hours of screen time (p = 0.002, p = 0.002, p = 0.012, respectively). The ratio of participants with high-lability/negativity (L/N) score was significantly higher in children with screen time of ≥ 4 hours and not co-viewing with parents (p = 0.004, p = 0.033, respectively).Conclusions. This study investigating the relationship between the emotion regulation skill and screen time revealed that excessive screen time is associated with emotional lability in this early childhood period.

ABSTRACT

INTRODUCTION: In studies directed to children and adolescents, the sedentary behavior has been usually represented by exposure to screen, which comprise the total or separate measured time exposed to television, videogame, tablets, mobile devices, and computer. OBJECTIVE: To analyze the prevalence and factors associated with screen time in children and adolescents. METHODS: A cross-sectional school-based study was carried out with 1,471 students from Elementary School, aged between 7 to 18 years (51.3% male), enrolled at public schools (55.6%) in Porto Velho, Rondônia (RO) state, Brazil. Excess screen time was defined as watching television, using the computer, and playing video games for more than two hours per day. Poisson regression was used to obtain crude and adjusted prevalence ratios and their respective 95% CI. RESULTS: Overall prevalence of screen time exposure over two hours per day was 65.9%. After adjustments, risk of screen time exposure was higher in males, PR = 1.51 (95% CI: 1.08 - 1.92), under or equal to 14 years old, PR = 1.69 (95% CI: 1.48 - 1.92), in the 5th grade, PR = 1.41 (95% CI: 1.02 - 1.89), in the 6th grade, PR = 1.44 (95% CI: 1.06 - 1.97) and in the 7th grade, PR = 1.52 (95% CI: 1.09 - 2.13), attending two weekly PE classes or fewer, PR = 1.25 (95% CI: 1.07 - 1.53) ), consuming more than 3 daily meals, PR = 2.69 (95% CI: 2.14 - 3.37) and overweight, PR = 1.51 (95% CI: 1.13 - 2.03). CONCLUSION: The findings showed that the exposure equal to or more than two hours of daily screen time was high. The students more exposed to this outcome had the next characteristics: male sex, age less than or equal to 14 years, from the fifth, sixth, and seventh grade of elementary education, practice physical education classes less than or equal to two hours per week, consume more than three meals daily and have excess body fat (G%).


INTRODUÇÃO: Em estudos direcionados a crianças e adolescentes, o comportamento sedentário tem sido usualmente representado pela exposição aos comportamentos de tela, que compreendem as medidas (unificadas ou distintas) do tempo de televisão, videogame, tablets, aparelhos celulares e computador. OBJETIVO: Investigar a prevalência e os fatores associados ao tempo de tela em crianças e adolescentes. MÉTODO: Estudo transversal de base escolar, com 1471 escolares de 9 a 18 anos, sendo 51,3% do sexo masculino pertencentes às escolas públicas (55,6%) do ensino fundamental de Porto Velho, Rondônia. O tempo excessivo de tela foi definido como assistir televisão, usar o computador e jogar videogames por mais de duas horas diárias. Análise utilizada foi regressão de Poisson para obtenção das razões de prevalências brutas e ajustadas e seus respectivos IC95%. RESULTADOS: A prevalência geral de exposição de tempo de tela maior que duas horas diárias foi de 65,9%. Após ajustes, o risco à exposição de tempo de tela foi maior no sexo masculino RP = 1,51 (IC95%: 1,08 - 1,92), idade menor ou igual a 14 anos RP = 1,69 (IC95%: 1,48 - 1,92), graus de ensino 5ª ano RP=1,41 (IC95%: 1,02 - 1,89), 6ª ano RP=1,44 (IC95%: 1,06 - 1,97) e 7ª ano RP = 1,52 (IC95%: 1,09 - 2,13), frequentar as aulas de educação física menos ou igual a duas aulas semanais RP = 1,25 (IC95%:1,07 - 1,53), consumir refeições diárias mais de três por dia RP = 2,69 (IC95%:2,14 - 3,37) e ter excesso de gordura RP = 1,51 (IC95%: 1,13 - 2,03. CONCLUSÃO: Os resultados mostraram que a exposição igual ou superior a duas horas de tela diária era alta. Os estudantes mais expostos a este desfecho tiveram as seguintes características: sexo masculino, idade menor ou igual a 14 anos, de quinta, sexta e sétima série do ensino fundamental, praticar aulas de educação física menor ou igual a duas horas semanais, consumir mais de três refeições diárias e estar com excesso de gordura corporal (G%).

ABSTRACT

Abstract This study analyzed the validity and reliability of an instrument with scales measuring factors associated with screen time in adolescents. Two cross-sectional studies included students for analyses of validity and internal consistency (n=1138, 51.5% boys) and test-retest reproducibility (n=194, 56.2% boys). Individual (attitude, self-efficacy and expectations), social (behaviors, rules, beliefs and family support and support of school members) and physical environmental (home and bedroom equipment) factors of screen time were evaluated. All the scales of the instrument met the statistical criteria of the validity of the exploratory factorial analysis (p<0.001). The exploratory factorial analysis indicated five one-dimensional and three two-factor scales (self-efficacy, expectations and familiar behavior), with factorial loads of 0.56 to 0.88. There were significant correlations between the scores of almost all the scales and the reported screen time (p<0.05). Eight of nine scales/subscales showed Cronbach's α value being higher than 0.70, and ICC ranged from 0.63 to 0.83. In conclusion, the instrument presented scales with acceptable validity and reliability and can be used to measure factors associated with screen time in Brazilian students.


Resumo Este estudo analisou a validade e a confiabilidade de um instrumento com escalas de fatores associados ao tempo de tela em adolescentes. Dois estudos transversais incluíram escolares para análises de validade (n=1138, 51,5% meninos) e reprodutibilidade teste-reteste (n=194, 56,2% meninos) do instrumento. Fatores individuais (atitude, autoeficácia e expectativas), do ambiente social (comportamentos, regras, crenças e suporte familiar e suporte dos membros da escola) e físico (casa e no quarto) associados ao tempo de tela foram avaliados. Todas as escalas do instrumento atenderam os critérios estatísticos de validade da análise fatorial exploratória (p<0.001). A análise fatorial exploratória indicou cinco escalas unidimensionais e três bi-dimensionais (autoeficácia, expectativas e comportamento familiares), com cargas fatoriais de 0,56 a 0,88. Houve correlações significativas entre quase todas as escalas e o tempo de tela reportado (p<0,05). Oito das nove escalas apresentaram um valor de α de Cronbach superior a 0,70, e o CCI variou de 0,63 a 0,83. O instrumento apresentou escalas que se apresentaram com validade e confiabilidade aceitáveis, podendo ser utilizado na mensuração de fatores associados ao tempo de tela em escolares brasileiros.

ABSTRACT

Resumo O uso de mídias por crianças na primeira infância está cada vez mais habitual, o que torna necessário investigar os fatores determinantes para o tempo de tela, entendido como o tempo total pelo qual a criança permanece exposta a todas as telas, incluindo televisão e mídias interativas. Trata-se de um estudo transversal, descritivo e exploratório, realizado com 180 crianças, entre 24 a 42 meses de idade, alocadas em: Grupo 1, exposição à tela inferior a duas horas/dia; Grupo 2, exposição à tela igual/superior a duas horas/dia. Realizou-se análise bivariada e de regressão logística binária. Os fatores determinantes no tempo de tela estudados foram os recursos do ambiente familiar, investigado por meio do Inventário de Recursos do Ambiente Familiar; fatores socioeconômicos; estado nutricional e status do desenvolvimento infantil, mensurado pelo teste Bayley III. Como resultado verificou-se que 63% das crianças apresentaram tempo de tela superior a 2 horas/dia e que a televisão ainda é a principal responsável pela exposição das crianças às telas. Observou-se que o tempo de exposição à tela esteve positivamente associado aos recursos familiares, nível econômico e desenvolvimento da linguagem. Entretanto, apenas os dois últimos fatores explicaram o maior tempo de tela.


Abstract The use of media by children in early childhood is increasingly common, and it is necessary to investigate the determinants of screen time, which is understood as the total child screen exposure time, including television and interactive media. This is a descriptive, exploratory, and cross-sectional study conducted with 180 children between 24 and 42 months of age, allocated in Group 1, less than two hours daily screen exposure time; Group 2, daily screen exposure time equal to or more than two hours. Bivariate and binary logistic regression analyses were performed. Screen time determining factors studied were family environment, evaluated with the Family Environment Resource Inventory; socioeconomic factors; nutritional status and child development status, evaluated with the Bayley III test. As a result, 63% of children had daily screen time exceeding two hours, and television still is the main culprit for children screen exposure. We observed that screen time exposure was positively associated with family resources, economic level, and language development. However, only the last two factors explained the longer screen time.

ABSTRACT

Our aim was to characterize the Brazilian studies that evaluated sedentary behavior, describing the main characteristics of the studies and identifying the used instruments. Using the PRISMA meth-odology, the search occurred on 25 August 2019 and was updated on 17 October 2020 in the fol-lowing databases: PUBMED, LILACS, and SCIELO. Studies in English, Spanish, and Portuguese were included. The inclusion criteria were studies performed with a sample of Brazilians, and that used an instrument to evaluate sedentary behavior. In total, 229 articles were selected. The majority of the studies evaluated children and adolescents. Only 33 studies used device-derived measures and there was a great variability in the questionnaires used. Only 83/198 studies presented quality criteria for the instrument used. Most studies considered the screen time in a typical week plus weekend to characterize sedentary behavior. Therefore, sedentary behavior in Brazil has mostly been evaluated by different questionnaires, and few have been appropriately validated. These findings emphasize the importance of standardization and methodological rigor for assessing sedentary behavior in the Brazilian context


Nosso objetivo foi caracterizar os estudos brasileiros que avaliaram o comportamento sedentário, descrevendo as principais características dos estudos e identificando os instrumentos utilizados. Utilizando a metodologia PRISMA, a busca ocorreu em 25 de agosto de 2019 e foi atualizada em 17 de outubro de 2020 nas seguintes bases de dados: PUBMED, LILACS e SCIELO. Estudos em inglês, espanhol e português foram incluídos. Os critérios de inclusão foram estudos realizados com uma amostra de brasileiros e que utilizassem um ins-trumento para avaliar o comportamento sedentário. No total, foram selecionados 229 artigos. A maioria dos estudos avaliou crianças e adolescentes. Apenas 33 estudos usaram medidas derivadas de dispositivos e houve uma grande variabilidade nos questionários usados. Apenas 83/198 estudos apresentaram critérios de quali-dade para o instrumento utilizado. A maioria dos estudos considerou o tempo de tela em uma semana típica mais o fim de semana para caracterizar o comportamento sedentário. Portanto, o comportamento sedentário no Brasil tem sido avaliado em grande parte por diferentes questionários, e poucos foram devidamente va-lidados. Esses achados enfatizam a importância da padronização e do rigor metodológico para avaliação do comportamento sedentário no contexto brasileiro

ABSTRACT

Objectives: To assess the relationship between screen times and sleep quality of the age group 17-24. Methodology: This is a cross-sectional study. The study was conducted on students of Colleges and universities in Gulshan-e-Iqbal Town Karachi. A total of 600 undergraduate students were approached in colleges and universities of Gulshan Town, Karachi. The sampling technique was Multi Staged sampling. The research instrument comprised of 3 parts i) Demographic profile, ii) Sleep quality measures and iii) Screen time usage measures. Results: The mean total hour of sleep was 6.7 ± 1.5. The Mean Cumulative score of the components of the questionnaire was 7.47 ± 3.56, while 174 (29%) have Normal Sleep quality and 426 (71%) have poor sleep according to the questionnaire. The odds ratio suggests there were 4.23 times higher chances of poor sleep quality in students whose screen time was more than 2 hours on weekdays as compared to other students. (OR: 4.23, 95% CI: 2.66-6.72). The odds ratio suggests there were 24.15 times higher chances of poor sleep quality in students whose screen time was more than 2 hours on weekends as compared to other students (OR: 24.15, 95% CI: 11.192-52.11). Conclusion: As, negative impacts were determined within sleep quality, and increased screen watching of multiple versions of the devices (screen time), influencing the commended level of screen watching among university and college students (age 17-24) is an affair of public health.

O estudo foi realizado em estudantes de faculdades e universidades em Gulshan-e-Iqbal Town Karachi. Um total de 600 alunos de graduação foram abordados nessas instituicoes. A técnica de amostragem foi a amostragem Multi Staged. O instrumento de pesquisa compreendeu 3 partes i) Perfil demográfico, ii) Medidas de qualidade do sono e iii) Medidas de uso do tempo de tela. Resultados: A média de horas totais de sono foi de 6,7 ± 1,5. A pontuação média cumulativa dos componentes do questionário foi de 7,47 ± 3,56, sendo 174 (29%) com qualidade de sono normal e 426 (71%) com sono ruim, de acordo com o questionário. O odds ratio sugere que houve 4,23 vezes mais chances de má qualidade do sono em alunos cujo tempo de tela era superior a 2 horas durante a semana, em comparação com outros alunos (OR: 4,23, IC 95%: 2,66-6,72). O odds ratio sugere que houve 24,15 vezes mais chances de má qualidade do sono em alunos cujo tempo de tela era superior a 2 horas nos finais de semana em comparação com outros alunos (OR: 24,15, IC 95%: 11,192-52,11). Conclusão: Como os impactos negativos foram determinados na qualidade do sono e aumento da visualização da tela de várias versões dos dispositivos (tempo de tela), influenciar o nível recomendado de visualização da tela entre universitários e estudantes universitários (idade 17-24) é uma questão de saúde pública.

ABSTRACT

BACKGROUND@#The 2019 novel coronavirus disease (COVID-19) emerges in China, which spreads rapidly and becomes a public health emergency of international concern. Chinese government has promptly taken quarantine measures to block the transmission of the COVID-19, which may cause deleterious consequences on everyone's behaviors and psychological health. Few studies have examined the associations between behavioral and mental health in different endemic areas. This study aimed to describe screen time (ST), physical activity (PA), and depressive symptoms, as well as their associations among Chinese college students according to different epidemic areas.@*METHODS@#The study design is cross-sectional using online survey, from 4 to 12 February 2020, 14,789 college students accomplished this online study, participants who did not complete the questionnaire were excluded, and finally this study included 11,787 college students from China.@*RESULTS@#The average age of participants was 20.51 ± 1.88 years. 57.1% of the college students were male. In total, 25.9% of college students reported depression symptoms. ST > 4 h/day was positively correlated with depressive symptoms (β = 0.48, 95%CI 0.37-0.59). COVID-19ST > 1 h/day was positively correlated with depressive symptoms (β = 0.54, 95%CI 0.43-0.65), compared with COVID-19ST ≤ 0.5 h/day. Compared with PA ≥ 3 day/week, PA < 3 day/week was positively associated with depression symptoms (β = 0.01, 95%CI 0.008-0.012). Compared with low ST and high PA, there was an interaction association between high ST and low PA on depression (β = 0.31, 95%CI 0.26-0.36). Compared with low COVID-19ST and high PA, there was an interaction association between high COVID-19ST and low PA on depression (β = 0.37, 95%CI 0.32-0.43). There were also current residence areas differences.@*CONCLUSIONS@#Our findings identified that high ST or low PA was positively associated with depressive symptoms independently, and there was also an interactive effect between ST and PA on depressive symptoms.

ABSTRACT

BACKGROUND@#Previous studies have suggested that screen time (ST) has a negative effect on children's emotional and behavioral health, but there are few longitudinal studies that have been conducted with infants and toddlers. This study sought to examine the effect of ST in early childhood on emotional and behavioral problems in children aged 4 years, based on a birth cohort study in China.@*METHODS@#A total of 2492 children aged 4 years were enrolled in this study. The parents and guardians of each child completed a questionnaire that included items eliciting information on children's birth information, socio-demographic information at baseline, and ST at each follow-up. Emotional and behavioral problems were assessed using the Strengths and Difficulties Questionnaire (SDQ) at 4 years of age. Multivariate logistic analysis was used to explore the effects of ST on emotional and behavioral problems.@*RESULTS@#The percentages of children with ST > 0 h/day at age 0.5 years, ST > 2 h/day at age 2.5 years, and ST > 2 h/day at age 4 years were 45.7, 55.5, and 34.5% respectively. The prevalence of emotional and behavioral problems was 10.8%. ST at 6 months was a risk factor for emotional symptoms and hyperactivity at the age of 4 years. ST at age 2.5 years was a risk factor for hyperactivity at the age of 4 years. However, ST at age 4 years was a risk factor for total difficulties, conduct problems, peer problems, hyperactivity, and prosocial behavior.@*CONCLUSIONS@#Higher ST exposure at early childhood is associated with later emotional and behavioral problems. In particular, sustained high ST exposure is a risk factor for behavioral problems. These findings suggested the importance of controlling ST to prevent the occurrence of emotional and behavioral problems in the early years.

ABSTRACT

ABSTRACT Objective: To verify the prevalence of sleep quality and duration and its association with the level of physical activity, screen time and nutritional status in adolescents. Methods: This is a cross-sectional study with 1,432 adolescents (53.1%, female), ten to 14 years old (12.0±1.0 year) from public schools in Joao Pessoa, Northeast Brazil. Physical activity (≥300 vs. <300 minutes/week), screen time (≤2 vs. >2 h/day) and duration (<8 vs. ≥8 h/day) and perception of sleep quality (negative vs. positive perception) were measured by questionnaire. Nutritional status was assessed by body mass index (low weight / normal weight vs. overweight / obesity). Binary logistic regression was used to analyze association between variables, considering different aggregation of negative factors. Results: The prevalence of insufficient duration and negative perception of sleep quality was 12.6% (95%CI 10.9-14.4) and 21.0% (95%CI 18.9-23.1), respectively. There was a linear trend in the chance of the adolescents to present insufficient duration of sleep as a result of simultaneous negative factors (physical inactivity, excessive screen time, being overweight) (OR=4.31; 95%CI 1.50-12.48). Conclusions: Adolescents exposed simultaneously to low levels of physical activity, excessive screen time and overweight had a lower sleep duration.


RESUMO Objetivo: Verificar a prevalência da percepção da qualidade e duração do sono e sua associação com o nível de atividade física, tempo de tela e estado nutricional em adolescentes. Métodos: Trata-se de um estudo transversal com 1.432 adolescentes (53,1% do sexo feminino), de dez a 14 anos de idade (12,0±1,0 ano) e de escolas públicas de João Pessoa (PB). A atividade física (≥300 vs. <300 min/semana), o tempo de tela (≤2 vs. >2 h/dia) e a duração (<8 vs. ≥8 h/dia) e percepção da qualidade do sono (percepção negativa vs. percepção positiva) foram mensuradas por questionário. O estado nutricional foi avaliado pelo índice de massa corporal (baixo peso/peso normal vs. sobrepeso/obesidade). A regressão logística binária foi utilizada para analisar a associação entre as variáveis. Resultados: A prevalência de duração insuficiente e a percepção negativa da qualidade do sono foram de 12,6% (intervalo de confiança de 95% [IC95%] 10,9-14,4) e 21,0% (IC95% 18,9-23,1), respectivamente. Identificou-se tendência linear de aumento na chance de os adolescentes apresentarem duração insuficiente de sono com o aumento do número de fatores negativos (inatividade física, tempo excessivo de tela, excesso de peso corporal) a que eles estavam expostos (Odds Ratio [OR]=4,31; IC95% 1,50-12,48). Conclusões: Adolescentes expostos simultaneamente a baixos níveis de atividade física, tempo excessivo de tela e excesso de peso tiveram menor duração de sono.

ABSTRACT

ABSTRACT Objective To investigate relations between electronic screen use and eye health in a representative sample of the Brazilian population. Methods Data were collected online and analyzed at a private Brazilian hospital (Provisão Hospital, Maringá, Brazil). Male and female individuals aged 12 to 35 years participated in the study. A population-based cross-sectional survey based on a questionnaire developed using the Google Forms interface was carried out. The questionnaire was answered anonymously in order to ensure the confidentiality of data and the privacy of participants. Data were collected between October 13, 2020, and January 30, 2021. Results A total of 200 questionnaires were completed. Most responders were young people aged 18 to 27 years. Daily electronic device use time reported by responders ranged from more than 5 hours (150; 75.5%) to 3 to 5 hours/day (28; 14%) or 2 to 3 hours/day (16; 8%). Only a small proportion of responders (2.5%) used these devices less than 1 hour per day. Most participants had myopia (164; 84%) and/or astigmatism (151; 75.5%), whereas keratoconus was less prevalent (34; 17%). However, 92 participants were unable to say whether they had these diseases or not. Most participants reported eye symptoms after screen use (red eyes, fatigue, dry and gritty eyes and blurred vision). Mental issues such as smartphone dependence and difficulties to communicate while using electronic devices were also addressed. Most responders reported dependence and communication problems. Conclusions Most young people in this sample had sings of eye disease, including keratoconus. Smartphone dependence and addition was also observed. Findings presented may inform future studies and help health authorities to properly guide public health strategies aimed at eye disease prevention.


RESUMO Objetivo Investigar o uso de telas na saúde ocular em uma amostra populacional brasileira. Métodos Os dados foram adquiridos on-line, e as análises foram realizadas em uma clínica privada na Região Sul do Brasil. Os participantes foram indivíduos de 12 a 35 anos, de ambos os sexos. Foi realizada pesquisa transversal de base populacional por meio de questionário elaborado na plataforma Google Forms. O questionário foi respondido de forma anônima, mantendo o sigilo dos dados coletados e a privacidade dos participantes. A coleta de dados teve início em 13 de outubro de 2020 e término em 30 de janeiro de 2021. Resultados Foram respondidos 200 questionários. A maioria foi de jovens entre 18 e 27 anos. O tempo de uso de dispositivos eletrônicos durante o dia foi de mais de 5 horas para 150 (75,5%) entrevistados, 28 (14%) gastavam de 3 a 5 horas por dia, 16 (8%) de 2 a 3 horas por dia e uma pequena parte dos entrevistados (2,5%) usava menos de 1 hora por dia. A maioria dos participantes tinha miopia (164; 84%) e/ou astigmatismo (151; 75,5%). Ceratocone foi menos prevalente (34; 17%), entretanto 92 pessoas não sabiam a resposta. A maioria dos participantes teve problemas nos olhos após o uso da tela, como olhos vermelhos, cansados e secos, além de visão turva. Questões mentais, como dependência de smartphones e dificuldade de comunicação durante o uso do dispositivo, também foram abordadas. A maioria dos entrevistados demonstrou dependência e problemas de comunicação. Conclusões A maior parte dos jovens apresentou quadro de doenças oculares, incluindo ceratocone. Dependência e adição de smartphone também foram observados. Esses resultados apoiam a identificação de fatores associados à patologia ocular, servindo de base para estudos futuros, e podem auxiliar às autoridades de saúde no direcionamento adequado das atividades de prevenção e controle em saúde pública.

ABSTRACT

INTRODUCTION: Sedentary routines characterised by multimedia games favour an increase in the prevalence of obesity in schoolchildren and their parents. Thus, identifying the factors associated with screen time during childhood and adolescence is essential for the development of public health strategiesOBJECTIVE: To analyse whether excessive time in front of screens in children and adolescents is associated with nutritional, behavioural and parental factorsMETHODS: Cross-sectional study on 795 schoolchildren, of which 354 were male, aged between 7 and 17 years, and their parents (father or mother) from a municipality in southern Brazil. The screen time spent by the students was self-reported, obtained in hours, considering excessive to be ≥ 2 hours a day. The parents' nutritional profile was assessed in terms of body mass index (BMI). For the data analysis, the prevalence ratio (PR) was used and analysed using the Poisson regression, with 95% confidence intervals (CIRESULTS: We found a high frequency of overweight/obese students (30.9%), with low levels of cardiorespiratory fitness (53.7%), who spend ≥ 2 hours daily on the TV, computer or video games (57.1%). Screen time was associated with the prevalence of being overweight (PR = 1.06; CI = 1.00-1.13) and obesity (PR = 1.10; CI =: 1.03-1.18) among fathers, only among adolescentsCONCLUSION: Excessive screen time among adolescents was associated with the father's nutritional status. It is suggested that strategies to reduce screen time should be implemented from childhood, involving the entire family


INTRODUÇÃO: As rotinas sedentárias caracterizadas pelos jogos multimídias favorecem o aumento da prevalência do excesso de peso em escolares e seus paisOBJETIVO: Analisar se o tempo excessivo em frente às telas de crianças e adolescentes está associado com fatores nutricionais, comportamentais e parentaisMÉTODO: Estudo transversal com participação de 795 escolares, 354 do sexo masculino, com idade entre 7 a 17 anos, e seus pais (pai ou mãe), de um município do sul do Brasil. O tempo de tela dispendido pelo escolar foi autorreferido, obtido em horas, considerando como excessivo ≥ duas horas diárias. O perfil nutricional dos pais foi avaliado pelo índice de massa corporal (IMC). Para a análise dos dados, foi utilizada razão de prevalência (RP), analisada pela regressão de Poisson, e os intervalos de confiança (IC) para 95%RESULTADOS: Foi encontrada elevada frequência de escolares com sobrepeso/obesidade (30,9%), com baixos níveis de aptidão cardiorrespiratória (53,7%) e que dispendem ≥ duas horas diárias na TV, computador ou videogame (57,1%). O tempo de tela esteve associado com a presença de sobrepeso (RP: 1,06; IC: 1,00-1,13) e obesidade (RP: 1,10; IC: 1,03-1,18) do pai, somente entre os adolescentesCONCLUSÃO: O tempo excessivo em frente às telas em adolescentes associou-se com o estado nutricional do pai. Sugere-se que estratégias para redução do tempo de tela devem ser estimuladas desde cedo, envolvendo toda a família do escolar
