Association of screen exposure/sedentary behavior and precocious puberty/early puberty.

Background: In recent years, with the development of society, children's daily exposure to screen time has gradually increased. Screen exposure and sedentary behavior have brought a host of harms to children's lives. The aim of this study was to explore the effects of screen exposure and sedentary behavior on precocious puberty and early development. Methods: This is a cross-sectional study in the school-based population. A total of 3,560 children were recruited from Qufu City, Shandong province using multistage stratified cluster random sampling. All study subjects had a physical examination by professional pediatricians in October 2019, and were investigated with health questionnaires. Precocious puberty is defined as development of secondary sexual signs in boys before 9 years or in girls before 8 years. Screen time was calculated as the average of screen time on weekdays and weekend days, and sedentary time was calculated as the average of sedentary time on weekdays and weekend days. After adjusting for potential confounders, logistic regression was used to examine the association between screen exposure and sedentary behavior and early puberty and precocious puberty. Results: Sedentary time was a risk factor for precocious puberty and early development (OR = 1.428, 95% CI = 1.087-1.876) in girls without adjustment. No significant association was found between screen exposure and early puberty and early development both in girls and boys. Conclusions: Excessive sedentary behavior was associated with an increased risk of early puberty, especially in girls, while there was no significant association between screen exposure and early puberty and early development. In addition, further longitudinal investigations are needed to determine the causal relationship between screen exposure, sedentary behavior and precocious puberty.

The impact of social media screen-exposure time on suicidal ideation among Pakistani adolescents.

BACKGROUND: Adolescence is a crucial life stage for the individual identity formation. The growing employment of social media and screen-exposure among teenagers and the concerning rise in suicide ideation rates in this susceptible group both suggested this study. Thus, we explored the association between adolescents' suicidal ideation and their daily social media screen-exposure. METHODS: We surveyed 502 students, aged 13 to 19 years old, recruited in colleges and universities of Punjab, Pakistan. The survey was based on a 28-item self-reported questionnaire and demographic data collection. RESULTS: Approximately 40% of adolescents reporting suicidal ideation showed an extended social media screen-exposure, as well as significant depressive feelings and problematic personality traits. In particular, suicidal ideation increased by 0.39 for each one-unit increase in screen-exposure time and levels of depression increased by 0.21 times by unit of screen-exposure. The correlation coefficients further indicated a moderate positive association between depression and suicidal thoughts as well as personality traits played as mediators between social media screen-exposure time and suicidal ideation among adolescents. CONCLUSION: Our study found a positive association, even if modest, between the use of social media screens and suicidal ideation among adolescents. This evidence may suggest to adopt specific strategies to address the use of media among youths and prevent mental disorders related to the prolonged and inappropriate use of digital technologies in those users with a vulnerable personality.

The impact of parental migration on screen exposure among children aged 1-66 months in rural China.

BACKGROUND: Screen exposure, particularly recreational screen exposure, is an integral part of children's lives. However, little is known about how family factors influence children's excessive screen exposure, especially in the context of 69 million left-behind children experiencing parent-child separation in China. This study mainly concentrates on the correlation between parental migration, type of caregiver, depression and disciplinary practices of the caregiver and children's screen exposure, including average daily screen time (on weekdays or weekends) and screen content (recreational activities or learning activities). METHODS: For a cross-sectional study, we collected data of family basic features, parental migration status and children's screen use in the past week from caregivers of 1,592 children aged 1-66 months in Anhui province. Children were classified into left-behind children (LBC), previously left-behind children (PLBC) and never left-behind children (NLBC) based on their parental migration. Multiple linear regression and binary logistic regression were used to identified the association between family factors and children's screen exposure. RESULTS: Overall, PLBC had higher rates of screen exposure, as well as higher average daily exposure times, than NLBC and LBC. The results of logistic regression showed that PLBC had a higher likelihood of excessive screen use compared to NLBC (60 min/day, OR = 1.40, p < 0.05; 120 min/day, OR = 1.76, p < 0.05). The higher the score of disciplinary practices, the less time children spent on screens for entertainment (B = -3.37, p < 0.01). CONCLUSIONS: Our findings provide insights into the risks of children's screen exposure in different contexts of parental migration. The study emphasizes the urgent need to pay attention to PLBC's screen use and to strengthen caregivers' discipline and supervision over children's screen exposure.

Problematic screen exposure and oral health in preschool children: a comparison study.

OBJECTIVES: Recent studies have highlighted the association between problematic screen exposure (PSE) in preschool children and various health issues. This study aims to determine the relationship between PSE and oral/dental health as well as parafunctional oral habits in this population. METHODS: Healthy children aged 3 to 6 years who visited the pediatric dentistry outpatient clinic were included in the study. PSE was evaluated using the parent-reported 'Seven-in-Seven-Screen-Exposure Questionnaire'. An intraoral examination was conducted to record the number of decated, missing, and filled teeth, along with scores from the International Caries Detection and Assessment System II (ICDAS II), as well as dental plaque and gingival indices. RESULTS: A total of 210 mother-child pairs were included in the study, comprising 70 pairs with PSE and 140 pairs without PSE. The sociodemographic characteristics, frequency of daily tooth brushing behaviors, use of children's toothpaste, and regular dental examinations were statistically evaluated between the PSE and non-PSE group (p > 0.05). Additionally, there was no statistically significant difference between the groups in terms of having abnormal oral habits (p > 0.05). In the PSE group, the median scores for gingival and plaque index were significantly higher (p = 0.011 and p = 0.006, respectively). The median number of decayed teeth was significantly higher in the PSE group (p = 0.039). CONCLUSIONS: Turkish preschool children with PSE were found to have a significantly higher likelihood of experiencing poor oral health. Consequently, it is essential to conduct oral health examinations for Turkish preschool children exhibiting PSE. The study may have clinical implications for the evaluation of preschool children with problematic media use within dental practice.

Correlation of screen exposure to stress, learning, cognitive and language performance in children.

The omnipresence of mobile screens and convenience to operate them has led to increased screen time for young children whereas the sequelae of prolonged exposure are not known yet. 70 refugee children (RG) and 111 children of a clinical comparison group (CG) from a help-seeking population (age: M = 5.10; SD = 1.11; range 3.00-6.97 years) were assessed concerning their amount of daily screen exposure time in relation to parental education and distress. Salivary cortisol was collected as a marker for biological stress and children were tested concerning learning performance, non-verbal IQ and vocabulary with the Kaufmann Assessment Battery for Children (KABC-II). Language skills were assessed in educator rating. The amount of children's screen exposure was negatively related to parental education and positively to distress. In the CG, higher amounts of screen time were associated with elevated cortisol levels and lower learning scores. On both measures, the RG and CG only differed in the condition of screen time less than one hour/day, for higher amounts of screen time the CG approached the more problematic scores of the RG. Whereas in the whole sample the amount of screen time was negatively correlated to language performance, it was not correlated to non-verbal IQ-scores. As a higher amount of media exposure in our clinical comparison group is associated with elevated biological stress, decreased learning and lower language performance, it should be classified as a relevant environmental factor and regularly considered in clinical assessments of children and therapeutical interventions, especially in vulnerable subgroups.

Enhanced pitch discrimination in autistic children with unexpected bilingualism.

Some autistic children acquire foreign languages from exposure to screens. Such unexpected bilingualism (UB) is therefore not driven by social interaction, rather, language acquisition appears to rely on less socially mediated learning and other cognitive processes. We hypothesize that UB children may rely on other cues, such as acoustic cues, of the linguistic input. Previous research indicates enhanced pitch processing in some autistic children, often associated with language delays and difficulties in forming stable phonological categories due to sensitivity to subtle linguistic variations. We propose that repetitive screen-based input simplifies linguistic complexity, allowing focus on individual cues. This study hypothesizes that autistic UB children exhibit superior pitch discrimination compared with both autistic and non-autistic peers. From a sample of 46 autistic French-speaking children aged 9 to 16, 12 were considered as UB. These children, along with 45 non-autistic children, participated in a two-alternative forced-choice pitch discrimination task. They listened to pairs of pure tones, 50% of which differed by 3% (easy), 2% (medium), or 1% (hard). A stringent comparison of performance revealed that only the autistic UB group performed above chance for tone pairs that differed, across all conditions. This group demonstrated superior pitch discrimination relative to autistic and non-autistic peers. This study establishes the phenomenon of UB in autism and provides evidence for enhanced pitch discrimination in this group. Acute perception of auditory information, combined with repeated language content, may facilitate UB children's focus on phonetic features, and help acquire a language with no communicative support or motivation.

Sleep onset time as a mediator in the association between screen exposure and aging: a cross-sectional study.

Excessive screen exposure has become a significant health concern. This study investigates the impact of screen time on aging in middle-aged and elderly populations. Healthy working adults over 45 years old in Shanghai, China, underwent general and ocular examinations. Questionnaires collected demographics, medical history, and screen exposure details. Aging was assessed using the retinal age gap, defined as the difference between the retinal age predicted by deep learning algorithms based on fundus images and chronological age. Pathway analysis tested the mediation effect of sleep duration and onset time on the relationship between screen usage and retinal age gap. The retinal age gap increased with longer screen exposure, from 0.49 ± 3.51 years in the lowest tertile to 5.13 ± 4.96 years in the highest tertile (Jonckheere-Terpstra test, p < 0.001). Each additional hour of screen exposure accelerated the retinal age gap by 0.087 years (95% CI, 0.027, 0.148, p = 0.005) in the fully adjusted linear model. Sleep onset time mediated the impact of screen usage on the retinal age gap (indirect effect, ß = 0.11; 95% CI 0.04-0.24). The impact of screen usage in a light-off environment on the retinal age gap was fully mediated by sleep onset time (indirect effect, ß = 0.22; 95% CI 0.07-0.38), with the proportion being 100%. Our study identified a correlation between excessive screen time and a wider retinal age gap in middle-aged and elderly individuals, likely due to delayed sleep onset. To mitigate the adverse effects on the retina and aging, it is important to limit screen usage and avoid screens before bedtime.

Development of the evaluating the screen exposure of adolescents (ESEA) scale: A validation and reliability study.

PURPOSE: Adolescents today live in a world surrounded by electronic devices. They did not experience life before the internet and they are therefore called 'digital natives'. As a result of increased screen exposure among adolescents, many short-term and long-term health problems may occur. No measurement tool to date includes multidimensional variables of screen exposure other than the duration of the screen exposure. The aim of this study was to develop a scale that evaluates screen exposure within different dimensions and to confirm the reliability and validity of that scale. DESIGN AND METHODS: This study was methodological. The research was completed with 347 adolescents. A personal information form and the Evaluating the Screen Exposure of Adolescents (ESEA) scale were used for data collection. IBM SPSS Statistics 24.0 and IBM AMOS 24.0 software programs were used for data analysis, and descriptive statistics were used to analyse numerical variables. Exploratory and confirmatory factor analyses were conducted to determine the factorial structure of the scale. RESULTS: The scale was finalised with a total of 23 items within five factors, which are willingness/desire for screen exposure, socialisation, family control, procrastination tendency, and effects of prolonged screen exposure. The factor loadings of the scale vary between 0.370 and 0.825. The internal consistency coefficient (Cronbach's alpha value) of the total scale was found to be 0.79. CONCLUSION: The ESEA scale, which was psychometrically evaluated in this study, assesses the screen exposure of adolescents multidimensionally and provides consistent measurements. PRACTICE IMPLICATIONS: Nurses working with adolescents, and especially pediatric nurses and public health nurses, can use this measurement tool to assess the screen exposure of adolescents in a multidimensional way. This scale supports better problem definition and effective interventions by nurses considering multidimensional screen exposure.

Intergenerational care and rural childhood obesity in the digital era: Based on screen exposure perspective.

Background: Rural Chinese children are experiencing increasing obesity rates, yet studies often neglect the impact of IT and screen media growth on obesity risks in the context of intergenerational care, leading to incomplete strategies for the digital era. Methods: By comprehensively utilizing the data on rural children aged 6-17 from the China Family Panel Studies (CFPS) and the China Health and Nutrition Survey (CHNS), this study aims to test the logical chain and specific mechanisms regarding "intergenerational care - screen exposure - rural childhood obesity". We employ the Propensity Score Matching (PSM) and Generalized Propensity Score Matching (GPSM) methods to respectively address the self-selection biases associated with inter-generational care and children's screen exposure behaviors. Results: 1) Intergenerational care significantly increases screen exposure among rural children. 2) Gender bias increases the risk of screen exposure for rural boys under intergenerational care. 3) Children with higher screen exposure levels are more affected by intergenerational care, which further undermines parental supervision. 4) Children's screen exposure leads to increased sedentary time and higher probability of purchasing unhealthy foods, thereby exacerbating obesity. This process is facilitated by enhancing preferences for snacks, fast food, and beverages, and weakening preferences for physical activity. 5) GPSM analysis indicates that children's screen exposure has an inverted "U"-shaped impact on unhealthy dietary preferences and a "U"-shaped impact on activity preferences. It results in a nonlinear positive impact of screen exposure on obesity. This study reveals a positive association between screen exposure and obesity, offering new insights into how intergenerational care in the digital era may elevate obesity prevalence through excessive screen time for rural children.

Association of Screen Time Exposure With Autism Spectrum Disorder in Four to Six-Year-Old Children in Arar City, Saudi Arabia.

Background Autism spectrum disorder (ASD) is a psychopathologic disorder caused by several factors. The early signs include poor interaction and communication, delayed milestones, and repeated behavior patterns. This study aimed to assess the relationship between screen time and ASD severity and investigate the types of electronic devices associated with ASD in children aged four to six years in Arar City, Kingdom of Saudi Arabia (KSA). Methodology A cross-sectional study was conducted in primary healthcare centers (PHCs) in Arar City, KSA. The study enrolled all parents with children aged four to six years attending the PHCs in Arar City, KSA. Results The total sample size was 199 participants. Regarding the relationship between screen time exposure and ASD, there were variable screen time exposure durations, with 22.6% of children exposed for less than an hour, 30.7% for one to two hours, and 46.7% for more than two hours. Moreover, the type of electronic devices to which children were exposed varied, with smartphones being the most prevalent (68.3%). In terms of the age of children since exposure to electronic devices, the data indicated that 30.2% were exposed before the age of two, 35.2% between two and three years, and 34.7% after three years of age. Regarding the relationship with sociodemographic characteristics, there was a statistically significant relationship with the mother's age at birth (p = 0.050), mother's education level (p = 0.009), father's education level (p = 0.049), whether the child was suffering from any chronic or neurological disease (p = 0.008), age since the child was exposed to electronic devices (p = 0.049), and screen time exposure duration (p = 0.040). Conclusions The study highlights the significant association between screen time exposure and the development of ASD in children. Public awareness of this associated risk among caregivers is recommended to follow the protective guidelines. Further research and interventions are needed to better understand and address the impact of screen media use on children's neurodevelopment and overall well-being.

A study of the effects of screen exposure on the neuropsychological development in children with autism spectrum disorders based on ScreenQ.

PURPOSE: To investigate the relationship between multi-dimensional aspects of screen exposure and autistic symptoms, as well as neuropsychological development in children with ASD. METHODS: We compared the ScreenQ and Griffiths Development Scales-Chinese Language Edition (GDS-C) of 636 ASD children (40.79 ± 11.45 months) and 43 typically developing (TD) children (42.44 ± 9.61 months). Then, we analyzed the correlations between ScreenQ and Childhood Autism Rating Scale (CARS), and GDS-C. We further used linear regression model to analyze the risk factors associated with high CARS total scores and low development quotients (DQs) in children with ASD. RESULTS: The CARS of children with ASD was positively correlated with the ScreenQ total scores and "access, frequency, co-viewing" items of ScreenQ. The personal social skills DQ was negatively correlated with the "access, frequency, content, co-viewing and total scores" of ScreenQ. The hearing-speech DQ was negatively correlated with the "frequency, content, co-viewing and total scores" of ScreenQ. The eye-hand coordination DQ was negatively correlated with the "frequency and total scores" of ScreenQ. The performance DQ was negatively correlated with the "frequency" item of ScreenQ. CONCLUSION: ScreenQ can be used in the study of screen exposure in children with ASD. The higher the ScreenQ scores, the more severe the autistic symptoms tend to be, and the more delayed the development of children with ASD in the domains of personal-social, hearing-speech and eye-hand coordination. In addition, "frequency" has the greatest impact on the domains of personal social skills, hearing-speech, eye-hand coordination and performance of children with ASD.

A greater modulation of the visual and fronto-parietal networks for children in a post-media versus pre-media exposure group.

AIM: Media use in children has exploded in the past several decades, most recently fuelled by portable electronic devices. This study aims to explore differences in functional brain connectivity in children during a story-listening functional MRI (fMRI) task using data collected before (1998) and after (2013) the widespread adoption of media. METHODS: Cross-sectional data were collected from English-speaking 5- to 7-year-old children at Cincinnati Children's Hospital Medical Center, USA, of a functional MRI narrative comprehension task completed in 1998 (n = 22) or 2013 (n = 25). Imaging data were processed using a graph theory approach, focusing on executive functions, language and visual processing networks supporting reading. RESULTS: Group differences suggest more efficient processing in the fronto-parietal network in the pre-media group while listening to stories. A modulation of the visual and fronto-parietal networks for the post-media exposure group was found. CONCLUSION: Further studies are needed to assess effects over time in the more exposed group to discern a causal effect of portable devices on cognitive networks.

Unsupervised Screen Exposure and Poor Language Development: A Scoping Review to Assess Current Evidence and Suggest Priorities for Research.

Screen exposure has both negative and positive effects on the level of language skills a child acquires. The purpose of this review is to address current literature on the possible relationship between unsupervised screen exposure and language development in children and to provide recommendations to caregivers regarding screen exposure of children, taking into consideration the possible effects. A scoping review was conducted using the PubMed/MEDLINE (Medical Literature Analysis and Retrieval System Online) database. A total of 590 articles were retrieved and considered for inclusion. Twenty-one articles were finally included and reviewed with an emphasis on language, communication, and executive skills as well as cognitive development. The negative effects of screen exposure for children outweigh the positive effects. The largest number of studies demonstrate that unsupervised screen exposure may negatively impact a child's language usage and cognitive and executive skills, disrupt playtime, and affect the quality of sleep. On the other hand, supervised screen use is associated with improved language skills. More evidence is needed on unsupervised exposure in children to new types of screens. As technology could play a significant role in schools in the future, additional research is required to create educational media for schoolchildren with specific guidelines.

The Impact of Screen Exposure on Screen Addiction and Sensory Processing in Typically Developing Children Aged 6-10 Years.

As technology continues to develop, children are spending more time in front of screens, which can lead to significant problems. For children aged 5 years and above, screen time of 2 or more hours per day on average is considered problematic. This study aimed to investigate the impact of screen exposure on screen addiction and sensory processing in typically developing children aged 6-10 years. The study analyzed 74 children who had a screen exposure time of 2 h or more and 71 children who had a screen exposure time of less than 2 h. The Dunn Sensory Profile was used to evaluate sensory processing skills, and the Problematic Media Use Scale was used to measure screen addiction. The group with high screen exposure showed statistically significant differences in screen addiction, distraction, and sedentary factors (p < 0.05). No significant differences were found in other parameters. Based on these findings, it has been determined that excessive screen exposure leads to a more sedentary lifestyle, increased screen addiction, and distraction in typically developing children aged 6-10 years. It is important to consider the duration of screen exposure in typically developing children aged 6-10 years and to conduct further studies on this topic.

"nem sempre funciona, mas ajuda": percepções parentais sobre a exposição do bebê às telas / "it doesn't always work, but it helps": parental perceptions of baby's screen exposure

RESUMO. Frente ao número crescente de crianças menores de dois anos expostas às telas, preocupações com o desenvolvimento dos bebês têm emergido e sido foco de discussões acadêmicas e clínicas. Para buscar compreender as razões que levam os pais a disponibilizarem as mídias digitais aos bebês, entrevistas foram conduzidas com mães e pais de crianças com idades entre dez e 17 meses, domiciliados na região metropolitana de Porto Alegre, Brasil. Apesar das orientações das sociedades de pediatria, verifica-se discrepância entre a divulgação deste conteúdo e o acesso a ele. Os pais, por desconhecimento e também por necessidade, disponibilizam diferentes mídias ao bebê, que é percebida em diversas situações como positiva e facilitadora nos cuidados com a criança; os pais alegam que o acesso precoce pelo bebê é importante para aprimorar a destreza cognitiva e capaz de gerar interação familiar. Por outro lado, apresentam preocupações diante do uso de telas em detrimento de outras formas de brincar. Evidencia-se que os pais precisam de orientações e suporte, assim como os profissionais devem considerar as necessidades das famílias ao elaborar diretrizes a fim de orientá-los.

RESUMEN Frente al creciente número de niños menores de dos años expuestos a las pantallas, preocupaciones sobre el desarrollo de los bebés han sido el foco de discusiones académicas y clínicas. Para comprender porque madres y padres exponen a sus hijos a tecnologías digitales se han realizado entrevistas en profundidad con madres y padres de bebés con edades entre 10 y 17 meses, domiciliadas en la región metropolitana de Porto Alegre, Brasil. A pesar de las pautas recomendadas por las sociedades pediátricas sobre al acceso a las pantallas, los padres muestran discrepancia acerca de las mismas. Los progenitores, debido tanto a la falta de conciencia, como a la necesidad comparten sus dispositivos con los bebés. Los padres afirman estar preocupados por el futuro de los niños y perciben el acceso temprano a la tecnología como una herramienta importante para mejorar las habilidades cognitivas y fortalecer los lazos familiares. También señalaron que las potencialidades en el uso para generar interacciones familiares, destacando la supervisión de los padres. Por otro lado, los padres manifiestan preocupación ante el uso de la tecnología a expensas de otras formas de juego. Los progenitores necesitan orientación y apoyo, al igual que los profesionales deben considerar las necesidades de las familias al formular recomendaciones.

ABSTRACT. Considering the large number of children under the age of two that are constantly exposed to digital screens, concerns about child development have been emerging and becoming the focus of academic and clinical discussions. In order to understand the reasons why parents expose their infants to digital technologies, we conducted in-depth interviews with mothers and fathers of infants aged between 10 and 17 months living in the metropolitan region of Porto Alegre, Brazil. Despite the guidelines of local pediatric societies, our data points to divergences between what is recommended by the board of pediatrics and the patterns of screen exposure documented in our study. Parents, out of unawareness and/or urgent need, introduce their babies to digital technologies. Parents claimed to be concerned with the future of children and perceived early access to digital technology as an important tool to improve cognitive skills and to strength family bonds. Conversely, parents had concerns in face of technology at the expense of other forms of play. Our findings highlight that parents need additional guidance and support, while professionals should weight needs and daily challenges experienced by families when formulating guidelines.

Precocious Puberty Diagnoses Spike, COVID-19 Pandemic, and Body Mass Index: Findings From a 4-year Study.

Context: Since the COVID-19 outbreak, the number of girls with suspected precocious puberty has increased. Objective: To compare the incidence of idiopathic central precocious puberty (ICPP) during COVID-19 with that of the previous 4 years. Methods: Anthropometric, biochemical, and radiological parameters were collected between January 2016 and June 2021 from 133 girls who met the Rapidly Progressive ICPP criteria (RP-ICPP). Results: We found a higher incidence of RP-ICPP between March 2020 and June 2021 (group 2) compared with January 2016 through March 2020 (group 1) (53.5% vs 41.1%); 2021 showed the highest annual incidence (P < .05). Group 1 and group 2 differed in age at diagnosis (7.96 ± 0.71 vs 7.61 ± 0.94; P < .05), mean Tanner stage (2.86 ± 0.51 vs 2.64 ± 0; P < .05), and in the time between the appearance of thelarche and diagnosis (0.93 ± 0.75 vs 0.71 ± 0.62 years, P < .05). There was an increase in the number of girls aged <8 years in group 2 and a significantly higher number of girls aged >8 years was found in group 1 (42 in group 1 vs 20 in group 2, P < 0.05). Overall body mass index SD score showed higher values ​​in group 2 (1.01 ± 1.23 vs 0.69 ± 1.15; P = .18), which spent an average of 1.94 ± 1.81 hours per day using electronic devices; 88.5% of this group stopped any physical activity. Conclusions: A spike in new diagnoses of idiopathic (1.79-fold higher) and RP-CPP coincided with the COVID-19 pandemic. The incidence of RP-ICPP was 1.3-fold higher during COVID-19 with a trend toward an increase in body mass index SD score. The expanding use of digital devices and the reduction of daily physical activity represent possible risk factors.

Early Screen-Time Exposure and Its Association With Risk of Developing Autism Spectrum Disorder: A Systematic Review.

Autism spectrum disorder (ASD) is a neurological deficit in brain functions that prevents a child from having a normal social life like his peers. It results in the inability to interact and communicate with others. Unsurprisingly, the alarming increase in screen-time exposure in children has become even more of a concern. Electronic devices are a double-edged sword. Despite their benefits, they have many potential hazards to children's neurological development. Previous studies have investigated the effects of unsupervised screen time and its impact on white matter development during the early years of life of children. The white matter has an important role in the development of neurological functions. This systematic review aims to qualitatively analyze the literature available on early screen time exposure and its association with the risk of developing ASD. This systematic review implemented the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020 guidelines. PubMed, PubMed Central (PMC), Google Scholar, and Cochrane Library databases were searched for data in the recent six years. A total of 27,200 articles were identified using the MeSH and keywords through four selected databases. Search results revealed 70 from PubMed, 17,700 from Google Scholar, zero from Cochrane Library, and 9,430 from PubMed Central. After applying filters and screening the results by title and abstract and then by full text, 11 studies fulfilled the criteria to be included in the review. We found that the longer the period of screen exposure, the higher the risk that the child may develop ASD. Further, the earlier the child is exposed to screens, the higher the risk of developing ASD in children compared to children exposed later.

Effects of Excessive Screen Time on Child Development: An Updated Review and Strategies for Management.

Children's heavy reliance on screen media has raised serious public health issues since it might harm their cognitive, linguistic, and social-emotional growth. This study examines the effects of screen time on many developmental domains and covers management and limitation techniques for kids' screen usage. Screen media has a wide range of cognitive consequences, with both beneficial and detrimental effects noted. Screens can improve education and learning; however, too much time spent in front of a screen and multitasking with other media has been related to worse executive functioning and academic performance. As screen time reduces the amount and quality of interactions between children and their caregivers, it can also have an impact on language development. Contextual elements like co-viewing and topic appropriateness are key in determining how language development is impacted. Additionally, excessive screen usage has detrimental effects on social and emotional growth, including a rise in the likelihood of obesity, sleep disorders, and mental health conditions including depression and anxiety. It can obstruct the ability to interpret emotions, fuel aggressive conduct, and harm one's psychological health in general. Setting boundaries, utilizing parental controls, and demonstrating good screen behavior are all techniques that parents may use to manage children's screen usage. We can reduce the possible negative impacts of excessive screen time and promote children's healthy development and well-being by increasing knowledge and encouraging alternative activities that stimulate development.

Infants' and toddlers' language development during the pandemic: Socioeconomic status mattered.

The disruption caused by the COVID-19 pandemic has raised concerns about children's development. Here, we examined the impact of the pandemic on Canadian infants' and toddlers' (N = 539) language development. Specifically, we assessed changes in 11- to 34-month-olds' activities that are known to affect vocabulary development (i.e., screen and reading times). We also compared these children's vocabulary sizes with those of 1365 children collected before the pandemic using standardized vocabulary assessments. Our results show that screen and reading times were most negatively affected in lower-income children. For vocabulary growth, no measurable change was detected in middle- and high-income children, but lower-income 19- to 29-month-olds fared worse during the pandemic than during pre-pandemic times. Moving forward, these data indicate that educators and policymakers should pay particular attention to children from families with lower socioeconomic status during times of crisis and stress.

The challenges of screen time in children with typical development and children with developmental disorders during COVID-19 pandemic.

Background: The significant lifestyle changes that occurred during the lockdown period associated with the COVID-19 pandemic may have had many potential adverse effects on children, in particular, sedentary screen exposure among children, including those with developmental disorders. We conducted a cross-sectional study to investigate and compare the screen time and outdoor activity time of children with typically development (TD) and those with developmental disorders during and before the emergence of COVID-19, and identified the risk factors related to screen time during the COVID-19 pandemic. Methods: A total of 496 children were surveyed via online questionnaires. Parents or/and children filled in the online questionnaire, including basic characteristics, screen time, outdoor activity time, and other related factors. The Statistical Product and Service Solutions software was used to analyze all data. Results: Children spent less time outdoors (t=14.774, P<0.001) and more time on electronic screens (t=-14.069, P<0.001) during the lockdown period of COVID-19, compared to the periods before COVID-19. Age (P=0.037), pre-COVID-19 screen time (P=0.005), screen time used for learning/education (P<0.001), screen time of siblings (P=0.007), and use of screen devices as electronic babysitters (P=0.005) were risk factors for screen time during the COVID-19 pandemic, while restrictive use of electronic devices by parents (P<0.05) was a protective factor. The screen time of children with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD) was significantly longer than children with TD before COVID-19 pandemic, but there is no statistical difference during the COVID-19 pandemic. Conclusions: During the COVID-19 pandemic, children's screen exposure time increased, and outdoor activities decreased significantly. This represents a significant challenge, and we should focus our efforts on managing children's screen time and promoting healthier lifestyles, including children with typical development, as well as those with developmental disorders.
