Screen time and obesity prevalence in adolescents: an isotemporal substitution analysis

Abstract Background We examined the associations between screen time and adolescent obesity and the associations of reallocating screen time to other activities using isotemporal substitution models. Understanding the association between screen time and obesity may provide additional insights into effective obesity prevention strategies in adolescents. Methods We conducted a cross-sectional analysis of 5,180 adolescents (4th and 7th grade students) from the Korean Children and Youth Panel Survey 2018. Participants reported their height, weight, and average time spent watching television, using computer, using smartphone, and other after-school activities. Obesity was defined as BMI-for-age and -sex ≥ 95th percentile based on the 2017 Korean National Growth Charts. We performed multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between screen time and obesity prevalence, adjusting for potential confounders. Results Prolonged smartphone use (≥ 180 vs. <60 m/d: OR [95% CI] = 2.75 [2.06, 3.68]) was associated with a higher obesity prevalence. Television watching (≥ 120 vs. <60 min/d) was positively associated with obesity prevalence among 4th grade students (2.09 [1.51, 2.89]) but the association was not observed among 7th grade students (0.97 [0.63, 1.49]). One-hour increments of any non-screen time activities, with a simultaneous 1-hour decrease in combined screen time, were associated with a lower obesity prevalence (physical activity: 0.75 [0.65, 0.85]; sleeping: 0.69 [0.62, 0.78]; hanging out with friends: 0.80 [0.71, 0.89]; reading: 0.82 [0.69, 0.97]; studying: 0.84 [0.78, 0.90]; chatting with parents: 0.89 [0.88, 0.98]). Conclusions Our data suggest that public health strategies that reduce screen time and increase time for non-screen time activities, such as physical activity, may be effective in lowering adolescent obesity prevalence.

Family conflict and less parental monitoring were associated with greater screen time in early adolescence.

The current study investigated the prospective relationships between parental monitoring, family conflict, and screen time across six screen time modalities in early adolescents in the USA. We utilised prospective cohort data of children (ages 10-14 years) from the Adolescent Brain Cognitive Development (ABCD) Study (years baseline to Year 2 of follow-up; 2016-2020; N = 10 757). Adjusted coefficients (B) and 95% confidence intervals (CIs) were estimated using mixed-effect models with robust standard errors. A higher parental monitoring score was associated with less total screen time (B = -0.37, 95% CI -0.58, -0.16), with the strongest associations being with video games and YouTube videos. Conversely, a higher family conflict score was associated with more total screen time (B = 0.08, 95% CI 0.03, 0.12), with the strongest associations being with YouTube videos, video games, and watching television shows/movies in Years 1 and 2. The current study found that greater parental monitoring was associated with less screen time, while greater family conflict was linked to more screen time. These results may inform strategies to reduce screen time in adolescence, such as improving communication between parents and their children to strengthen family relationships.

Reduction of screen induced myopia by parental interventions

Abstract Background Excessive use of digital devices, including smartphones and tablets, has been shown to increase the risk of myopia in children. Gaps persist in understanding parental attitudes towards handheld screen use and effective interventions guiding eye health policies. This study examined the associations between parental behavior related to myopia and children’s handheld screen use. Methods Data obtained from 395 parents of pre-adolescents (Mean age 10.63; SD 1.09) were used, collected from an online community panel. Parents reported on various behavioral determinants related to myopia and their child’s screen time: knowledge, attitude, risk perception and self-efficacy. They reported on their child’s frequency and amount of screen use. Logistic regression analysis was used to assess associations between variables, using parental efforts to reduce screens as outcome measure. Results Of the 395 participating 9-12 year-olds, 73.4% of the children spent up to two hours a day on recreational handheld screens, 26% more than two hours. Of the parents surveyed, 28.1% perceived the risk of screen-induced myopia as significant, prompting 62.6% of them to take active measures to minimize screen time. The more knowledge parents had on child myopia the more they attempted to reduce screen time (OR = 2.57; 95% CI [1.57-4.19], p = <.001). Moreover, a more negative attitude towards screens was significantly related to attempting to reduce screen time (OR = 1.26; 95% CI[1.17-1.35],p = <.001). Key messages • These findings emphasize a need to address parental knowledge and attitude towards myopia and screen time reduction. • We recommend increasing knowledge, influencing attitude and searching for alternatives as a part of behavioral change strategies.

7.N. Round table: Social media & smartphones: Threats to child & adolescent health and public health solutions

Abstract The daily lives of children and adolescents in 2024 are heavily influenced by social media and smartphones, which is unprecedented in previous generations. While this technology offers undoubted benefits, there is strong evidence on the negative effects of social and cognitive development of infants and primary school aged children, and mental health impacts in adolescents including depression, anxiety, sleep disruption, addictive behaviours and self-harm. Internet companies are financially incentivised to maximise screen time of users to generate advertising revenue, and more time spent by young people on these devices in a largely unregulated online domain increases risk of consequences like bullying and harassment, body dysmorphia, gambling addiction, porn addiction, sexual predation and suicide. Comprehensive solutions are urgently needed to regulate the activities of social media and tech companies and support young people to protect themselves from serious harms. Governments have been slow to introduce policies such as smartphone bans or enhanced privacy laws, perhaps because they are perceived as unpopular infringements on the rights of adult users and/or due to a potential detrimental effect on commercial interests. Guidance can be disseminated to young people, schools, families and institutions on how to reduce screen time and smartphone addiction, and improve coping and self-regulation to mitigate these risks. Information campaigns with positive health messages in this area, to compete with the advertising dominance of social media companies, are another opportunity to improve behaviours and reduce adverse health effects. The objectives of this round table workshop are to share examples of strategies, guidance and policies from across Europe, and discuss with the audience how the public health community can collaborate to tackle this problem. Members of the EUPHA Child and Adolescent Public Health (CAPH) section will outline the latest available evidence on the negative impacts of social media and screens, present examples of innovative public health responses and strategies to protect children, and engage conference participants for their input and discussion. Five panellists will present. First, John will start with a quiz of the audience which will include presentation of current data and trends relating to social media and smartphone usage. The second presentation by Cecilia will highlight in detail evidence of both benefits and adverse effects of these technologies in the lives of young people. The third speaker Karin will discuss examples of effective policies to reduce this impact, with a focus on the role of schools. The fourth speaker Jean will give further examples of public health actions, and share recommendations directly from children and young people. The fifth panellist Silja will re-quiz the audience, to gauge the reaction and support of solutions that were covered, and this will lead into the interactive discussion. Key messages • Popularity of smartphones and social media has increased dramatically in recent years, particularly among minors, with significant impacts on mental and physical health. • Public health solutions are urgently needed, and this workshop will share examples of effective innovative responses in European contexts, followed by an interactive audience discussion.

Toddler Screen Use Before Bed and Its Effect on Sleep and Attention

Toddler screen time has been associated with poorer sleep and differences in attention. Understanding the causal impact of screen time on early development is of the highest importance. To test (1) the feasibility of the 7-week parent-administered screen time intervention (PASTI) in toddlers (aged 16-30 months) who have screen time in the hour before bed and (2) the impact of PASTI on toddlers' sleep and attention. This assessor-blinded, UK-based randomized clinical trial was conducted between July 2022 and July 2023. This was a single-site study that enrolled families with a toddler aged between 16 and 30 months, living within 75 miles of the Babylab, and with 10 minutes or more of screen time in the hour before bed on 3 or more days a week. Exclusion criteria were (1) a genetic or neurological condition, (2) premature birth (<37 weeks), and (3) current participation in another study. Families were randomized (1:1:1) to (1) PASTI: caregivers removed toddler screen time in the hour before bed and used activities from a bedtime box instead (eg, reading, puzzles); (2) bedtime box (BB only): used matched before-bed activities, with no mention of screen time; or (3) no intervention (NI): continued as usual. Feasibility outcomes: participation rate, intervention adherence, retention, family experiences, and assessment acceptability. Efficacy outcomes: screen use, actigraphy-measured sleep, and eye-tracking attention measures. A total of 427 families were screened, 164 were eligible (38.4%), and 105 families were randomized (mean [SD] age, 23.7 [4.6] months; 60 male [57%]). The trial was feasible, with 99% participant (104 of 105) retention and 94% of families (33 of 35) adhering to PASTI. PASTI showed reductions in parent-reported screen time (vs NI: Cohen d = -0.96; 95% CI, -1.32 to -0.60; vs BB only: Cohen d = -0.65; 95% CI, -1.03 to -0.27). PASTI showed small to medium improvements in objectively measured sleep efficiency (vs NI: Cohen d = 0.27; 95% CI, -0.11 to 0.66; vs BB only: Cohen d = 0.56; 95% CI, 0.17-0.96), night awakenings (vs NI: Cohen d = -0.28; 95% CI, -0.67 to 0.12; vs BB only: Cohen d = -0.31; 95% CI, -0.71 to 0.10), and reduced daytime sleep (vs NI: Cohen d = -0.30; 95% CI, -0.74 to 0.13) but no difference compared with BB only. There was no observable effect of PASTI on objective measures of attention. Compared with BB only, PASTI showed a difference on parent-reported effortful control (Cohen d = -0.40; 95% CI, -0.75 to -0.05) and inhibitory control (Cohen d = -0.48; 95% CI, -0.77 to -0.19), due to an increase in BB-only scores. Results of this randomized clinical trial show that, supporting pediatric recommendations, removing screen time before toddler bedtime was feasible and showed modest preliminary beneficial effects on sleep. A future full confirmatory trial is needed before PASTI's adoption by parents and pediatricians. ISRCTN.org Identifier: ISRCTN58249751.

Recreational screen time and obesity risk in Korean children: a 3-year prospective cohort study

BackgroundStudies have shown that prolonged television watching increases obesity risk among children. However, few studies examined the associations with other types of screen time, such as computer and smartphone use, using a prospective cohort study design. Further, little is known about the specific non-screen time activity that may yield the most benefits when reallocating screen time to other activities.MethodsWe conducted a prospective cohort analysis using 3-year follow-up data from the Korean Children and Youth Panel Survey 2018 (n = 2,023; 4th grade elementary students who were not obese at baseline). Average time spent watching television, using computer and smartphone, and other after-school activities were self-reported at baseline. Weight and height were also self-reported at baseline and follow-up surveys through 2021. We performed multivariable logistic regression models to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between screen time and obesity incidence, adjusting for potential confounders. We also performed isotemporal substitution models to examine the associations of reallocating screen time to other non-screen time activities (physical activity, sleeping, hanging out with friends, reading, studying, and chatting with parents) in an equal time-exchange manner.ResultsLonger combined screen time (≥ 240 vs. <120 m/d) was statistically significantly associated with an increased obesity risk (OR [95% CI] = 1.68 [1.03, 2.73]). The direction of associations with television watching (≥ 180 vs. <60 m/d: OR [95% CI] = 2.86 [1.58, 5.20]), computer use (≥ 120 vs. <60 m/d: 1.38 [0.52, 3.64]), and smartphone use (≥ 180 vs. <60 m/d: 1.42 [0.76, 2.65]) were all positive, although the association was most apparent and statistically significant for television watching only. The associations did not change after additional adjustment for other lifestyle factors, including physical activity, sleep, and breakfast skipping. In the isotemporal substitution models, reallocating 1-hour of screen time to reading (OR [95% CI] = 0.67 [0.48, 0.93]) was associated with a decreased obesity risk. Reallocating 1-hour of screen time to physical activity was only marginally significantly associated with obesity risk (0.79 [0.62, 1.01]).ConclusionsOur data suggest that more efforts should focus on reducing screen time and increasing time for other non-screen time activities, particularly reading, for obesity prevention in children.

Understanding Digital Dementia and Cognitive Impact in the Current Era of the Internet: A Review.

Dementia encompasses symptoms resulting from brain damage that impairs cognitive functions, surpassing natural aging effects. This condition affects emotional regulation, behavior, and motivation while preserving consciousness. Dr. Manfred Spitzer coined the term 'digital dementia,' highlighting the cognitive decline associated with excessive reliance on digital devices such as smartphones and Google, potentially exacerbating attention deficit hyperactivity disorder (ADHD) and memory loss. This condition mirrors terms like 'digital amnesia' and 'the Google Effect,' highlighting the brain's tendency to offload peripheral information, leading to panic and forgetfulness. Spitzer's book, Digital Dementia, focuses on gaming effects on children and has thus popularized the term. Teenagers are known to use electronic devices regularly, correlating with rising cognitive impairments. The advent of the internet's fifth generation (5G) has transformed technology use, impacting mental health treatments and clinical practices globally. Digital media's influence on the developing brain encompasses motor skills, language, and cognition. Excessive digital media use in young adults correlates with lower cognitive empathy, affecting interpersonal understanding and facial recognition. Studies link heavy reliance on web-based media to decreased white matter integrity, crucial for language skills. Adolescents may be more vulnerable to anxiety and unrealistic expectations due to digital media overuse. Digital media overuse impacts brain development, especially cognitive and inhibitory control, attention, memory, and reasoning, essential for adapting to dynamic environments. Early exposure to fast-paced media can impair motor skills, spatial awareness, problem-solving, and language learning. Neuroimaging studies reveal that environmental factors like screen usage affect brain networks controlling social-emotional behavior and executive functions. Overreliance on smartphones diminishes gray matter in key brain regions, affecting cognitive and emotional regulation. The internet generation, characterized by advancements such as Web 3.0, introduces artificial intelligence and semantic web technologies, reshaping digital content processing. The neurobiological basis of digital dementia involves changes in the brain structure and function, with excessive screen exposure linked to cognitive impairments. Neuroplasticity, or the brain's adaptability, plays a role in cognitive decline from digital media overuse. Early childhood and adolescent brain development stages exhibit significant plasticity, influencing cognitive trajectories. Addressing digital dementia requires strategies to reduce screen time, promote cognitive exercises, and enhance awareness. Parents should regulate children's screen usage, encourage digital detox periods, and substitute screen time with other activities. Cognitive training programs such as Cogmed (Neural Assembly Int AB, Stockholm, SWE) and CogniFit (San Francisco, CA, USA) can improve memory and attention in older adults. Promoting balanced technology use and educating on the risks of excessive digital media consumption is crucial for maintaining cognitive health in the digital age.

From Screen to Depression: An Integrative Review Link Between Sedentary Lifestyle and Mental Health Issues

Background: Sedentary lifestyles, particularly high screen time, have been increasingly associated with mental health issues such as anxiety and depression among youth. Understanding these associations is crucial for developing effective interventions.Objective: This review aimed to assess the relationship between sedentary lifestyles and mental health outcomes, focusing on anxiety and depression in young populations globally.Methods: A comprehensive search of PubMed, Google Scholar, and APA PsycInfo was conducted using keywords such as "sedentary lifestyle," "screen time," "anxiety," "depression," and "mental health." Studies included cross-sectional, longitudinal, systematic reviews, and randomized controlled trials. Data on odds ratios, prevalence rates, and statistical connections were extracted and synthesized, following the PRISMA guidelines for narrative reviews.Results: The review included 40 studies published from 2011 to 2024. Findings indicated that screen time-related inactivity rates ranged from 23.2% to 62%, with depression prevalence between 15% and 25%, and anxiety prevalence from 10% to 20%. High screen time was strongly associated with increased mental health risks.Conclusion: Sedentary behavior and high screen time significantly impact youth mental health, emphasizing the need for targeted public health interventions to reduce screen time and promote active lifestyles.

REVISÃO CRÍTICA DAS ESTRATÉGIAS DE COMBATE AO SEDENTARISMO INFANTIL CAUSADO PELO USO EXCESSIVO DE TECNOLOGIA: UMA NOVA ABORDAGEM COM BASE NA LITERATURA

Childhood sedentary behavior, driven by excessive technology use, has become a growing concern in the field of children’s health. This study conducts a critical review of current strategies to combat childhood sedentary behavior, identifying the main gaps in existing approaches. Although screen time reduction is a common recommendation, interventions often fail to maintain long-term effectiveness, partly due to a lack of behavioral focus and integration of technology as a tool in promoting physical activity. Based on the literature review, this article proposes a new theoretical model that uses technology proactively, integrating it into gamified physical education programs, real-time monitoring, and family involvement. The suggested model aims to increase children’s adherence to physical activities and ensure the inclusion of low-income populations through strategic partnerships to broaden access to technological devices. The study concludes that integrating technology and health can offer more sustainable and effective solutions to reduce childhood sedentary behavior.

Adherence to the WHO physical activity, screen time and sleep guidelines and associations with socio-demographic factors among Ethiopian preschool children: The SUNRISE study

BackgroundThe World Health Organisation (WHO) has called for more evidence on 24-hour movement behaviours from low- and middle-income countries. We examined the proportion of Ethiopian children aged 3.0-4.9 years who met the WHO guidelines on physical activity, screen time and sleep for children under the age of five, and the associations between meeting the guidelines and socio-demographic factors.MethodsA cross-sectional study was conducted in Adama and Lume district, Ethiopia. Children were recruited through kindergartens in Adama city and rural villages of Lume district, Ethiopia. Physical activity and sleep were measured using ActiGraph accelerometer. Screen time and restrained sitting were parent-reported. Multivariable logistic regression models tested associations between meeting the individual and combined WHO guidelines and socio-demographic factors.ResultsA total of 430 children participated in the study (mean age 4.2 ± 0.6 years). More than half the children (58.0%) met all the WHO guidelines. A higher proportion met the physical activity (96.1%) and sleep guidelines (91.9%) compared to the screen time guideline (63.5%). Children who lived in rural areas were more likely to meet the screen time (84.6% vs. 38.2%, AOR = 7.31; 95%CI: 3.93, 14.02), sleep (98.6% vs. 83.8%, AOR = 8.60; 95%CI: 3.55, 23.73) and combined (81.3% vs. 30.1%, AOR = 7.41; 95%CI: 4.04, 13.97) guidelines than those who lived in urban areas.ConclusionsChildren from rural Ethiopia were more compliant with the WHO guidelines than their urban counterparts. Strategies to reduce screen time and promote healthy movement behaviours in urban areas are needed. Further studies with a larger representative sample might provide better insight across the regions within the country.

Effectiveness of a parent-focused intervention targeting 24-hour movement behaviours in preschool-aged children: a randomised controlled trial

BackgroundInterventions focusing on individual behaviours (physical activity, sedentary behaviour, sleep) of preschool-aged children have been widely studied. However, there is a lack of understanding about integrated interventions that target all three 24-hour movement behaviours. This is the first study to assess the effectiveness of an intervention aimed at improving all three 24-hour movement behaviours among preschoolers in Hong Kong.MethodsA 12-week randomised controlled trial with a 12-week follow-up was conducted. Parent-child pairs were randomised to integrated approach (targeting all three behaviours), dyadic approach (targeting physical activity and sedentary behaviour including screen time), or wait-list control group. Utilising the Internet-based delivery, this intervention consisted of education materials, workshops, and interactive questionnaires and reminders. Two intervention groups employed the same strategies, with the only difference being that the integrated approach targeted sleep in addition to physical activity and sedentary behaviour. The outcomes were preschoolers’ overall 24-hour movement behaviours which were assessed by the Activity Sleep Index (ASI), movement behaviour composition, and absolute duration of movement behaviours. Generalised estimating equations were conducted to evaluate the intervention.ResultsA total of 147 preschoolers (4.8 ± 0.9 years old, 56.5% boys) and their parents were included. Preschoolers in all groups had a lower ASI at follow-up compared with baseline. Preschoolers in the integrated approach had a smaller decline in ASI at follow-up, compared to that in the control group (3.41; 95% confidence interval [CI] = 0.07, 6.76). Preschoolers in both intervention groups had a smaller reduction of the composition of time spent in physical activity at follow-up, and a decreased screen time at postintervention and follow-up. No significant differences were found for the sleep subcomponent. Furthermore, preschoolers in the dyadic approach had a smaller increase in the sedentary behaviour subcomponent (vs. control: − 0.21; 95% CI = − 0.37, − 0.05) at follow-up.ConclusionsBoth intervention groups showed a decrease in screen time at postintervention, but there were no significant changes in other behaviours. The favourable changes observed at follow-up demonstrated the effectiveness of both intervention approaches on alleviating the decline in the composition of time spent in physical activity and reducing screen time and revealed the possible effectiveness of the integrated approach in promoting overall movement behaviours among preschoolers.Trial registrationThe study is prospectively registered at the Chinese Clinical Trial Registry (ChiCTR2200055958).

The Effect of Screen Habits and Alternative Activities on Tactile Exploration Skills in 6- to 36-Month-Old Toddlers.

With the rising ubiquity of digital media and screens in everyday life, toddlers are increasingly exposed to different screens from an early age (i.e., television, computer, tablet, phone). However, few studies have examined the effect of these screens on toddlers' perceptual development. Since tactile exploration skills are necessary for environmental discovery and overall development, the current research investigates the links between screen-use habits and the tactile exploration skills (with visual control) of 6- to 36-month-old toddlers. The study involved observing the interactions of 135 toddlers with various objects and assessing the complexity of their visuo-tactile exploration strategies through two original experimental tasks. Data concerning screen habits and other relevant factors, such as socio-economic level, were collected using a parental questionnaire. Toddlers with greater screen exposure time demonstrated weaker tactile exploration skills and employed less age-appropriate exploration strategies. Socio-economic factors and parental engagement in alternative activities significantly influenced these developmental outcomes. These findings emphasize the importance of reducing screen time and promoting interactive co-viewing and alternative activities to mitigate the negative effects of screen exposure. Further longitudinal research is needed to determine the long-term impacts of early screen exposure on tactile exploration and overall psychological development.

The digital aspects of the wellbeing of university teachers

IntroductionIn the past few decades more and more studies have put the mental health and wellbeing of university lecturers in the limelight, especially considering the fact that lecturers’ scope of responsibilities have been significantly transformed and expanded as a result of the massification and diversification of and structural changes in higher education. These changes intensified the workload, already rather high, thus negatively affecting lecturers’ wellbeing. It is worth investigating how the increasingly marked presence of digital technologies affects the characteristics of teachers’ workload. In this study, we intend to investigate the impact of digitization on the various areas of workload and work activities of university lecturers at a large university with many faculties, on the one hand, and teachers of institutions teaching in minority languages, on the other.MethodsThe online questionnaire compiled and based on the findings of our previous qualitative study was completed by teachers at one of Hungary’s biggest universities, the University of Debrecen, and lecturers at other institutions of higher education providing for the Hungarian ethnic minority across borders and affiliated with the University of Debrecen, altogether 596 people. The database created obtaining the data was named Central and Eastern European Teachers in Higher Education (CEETHE, 2023), IBM SPSS 29 software was used to analyze the data.ResultsDigital technology plays a basic role in lecturers’ work. Its importance is shown by the fact that the majority of respondents (54%) experiences significant or very severe stress in connection to technological problems. The majority of time spent with digital devices is included in working hours, so these technologies play a prominent role in dissolving the boundaries between professional and private life. Furthermore, many people find their use more exhausting than mental work performed without relying on them.ConclusionBy continuously developing the digital competency of university lecturers it is possible to mitigate the stress triggered by technological problems as well as reduce screen time. It is necessary to ensure that institutions of higher education introduce policies that ensure work-life balance for teachers.

Effects of outdoor activity time, screen time, and family socioeconomic status on physical health of preschool children.

Experienced 3 years of pandemic-induced home life, in the post-epidemic period, preschoolers in China are falling short of the World Health Organization's standards for screen time and outdoor activities. This notably impacts their physical well-being. The study aims to probe the associations between screen time, outdoor activities, and the physical health of preschoolers, offering insights to shape interventions targeting myopia and obesity prevention in children. A cross-sectional study was conducted in Guangdong Province, involving a representative sample of 23,992 preschoolers and their caregivers recruited through proportional stratified cluster sampling. Data collection utilized the Chinese Early Human Capability Index (CHeHCI, eHCi), a questionnaire on children's media use in daily family life, and Body Mass Index (BMI). Linear regression and binary logistic regression models were employed to analyze the impact of screen time and outdoor activity duration on the physical health of preschoolers. In the high family socioeconomic status (SES) group, children had significantly less screen time compared to those in the medium and low SES groups. Outdoor activity time varied significantly based on SES, with higher SES linked to extended outdoor engagement. Additionally, children's eHCi health dimension score exhibited significant SES-related differences, showcasing higher scores for children in higher SES groups. In terms of gender differences, boys dedicated significantly more time to outdoor activities than girls, yet boys had a notably higher overweight rate. Furthermore, girls demonstrated better health outcomes based on eHCi health scores. A significant association emerged between overweight and screen time in children with high SES, indicating that prolonged screen time was linked to a higher likelihood of overweight based on BMI. Additionally, a substantial negative correlation was observed between children's eHCi health dimension score and screen time. Furthermore, children's outdoor activity time exhibited a significant positive correlation with eHCi health dimension score. Regression analysis revealed that screen time could significantly negatively predict children's physical health score, while outdoor activity time could significantly positively predict children's eHCi physical health score. The current study highlights that family SES, age, and gender play pivotal roles in influencing preschoolers' screen time and outdoor activity duration, with family SES being particularly influential. Higher family SES correlates with reduced screen time, increased outdoor activity, and elevated health levels among children. Importantly, children's screen time negatively predicts their health status, while outdoor time positively predicts their health status.

How Parental Mediation and Parental Phubbing Affect Preschool Children's Screen Media Use: A Response Surface Analysis.

Parental mediation (PM) and parental phubbing (PP) are two pivotal factors that influence children's screen media use. This study used response surface analysis to examine the combined effect of PM and PP on screen time among preschool children. A total of 3,445 parents with preschool-aged children participated in this study, providing self-reported data on PM, PP, and their children's screen time (CST). The results revealed that CST decreased when parents enhanced their mediation behaviors and reduced phubbing behaviors in the cases of congruence between PM and PP. In instances of incongruence, reduced screen time was observed when parents exhibited lower frequency in mediating their CST and displayed fewer phubbing behaviors compared with situations where parents mediated their children more frequently but engaged in higher levels of phubbing behaviors. The findings suggest that PM play a significant role in mitigating preschool-aged children's excessive screen time. Moreover, it is critical to establish positive role modeling by reducing PP behaviors.

Evaluating artificial intelligence-enhanced digital urine cytology for bladder cancer diagnosis.

This study evaluated the diagnostic effectiveness of the AIxURO platform, an artificial intelligence-based tool, to support urine cytology for bladder cancer management, which typically requires experienced cytopathologists and substantial diagnosis time. One cytopathologist and two cytotechnologists reviewed 116 urine cytology slides and corresponding whole-slide images (WSIs) from urology patients. They used three diagnostic modalities: microscopy, WSI review, and AIxURO, per The Paris System for Reporting Urinary Cytology (TPS) criteria. Performance metrics, including TPS-guided and binary diagnosis, inter- and intraobserver agreement, and screening time, were compared across all methods and reviewers. AIxURO improved diagnostic accuracy by increasing sensitivity (from 25.0%-30.6% to 63.9%), positive predictive value (PPV; from 21.6%-24.3% to 31.1%), and negative predictive value (NPV; from 91.3%-91.6% to 95.3%) for atypical urothelial cell (AUC) cases. For suspicious for high-grade urothelial carcinoma (SHGUC) cases, it improved sensitivity (from 15.2%-27.3% to 33.3%), PPV (from 31.3%-47.4% to 61.1%), and NPV (from 91.6%-92.7% to 93.3%). Binary diagnoses exhibited an improvement in sensitivity (from 77.8%-82.2% to 90.0%) and NPV (from 91.7%-93.4% to 95.8%). Interobserver agreement across all methods showed moderate consistency (κ=0.57-0.61), with the cytopathologist demonstrating higher intraobserver agreement than the two cytotechnologists across the methods (κ=0.75-0.88). AIxURO significantly reduced screening time by 52.3%-83.2% from microscopy and 43.6%-86.7% from WSI review across all reviewers. Screening-positive (AUC+) cases required more time than negative cases across all methods and reviewers. AIxURO demonstrates the potential to improve both sensitivity and efficiency in bladder cancer diagnostics via urine cytology. Its integration into the cytopathological screening workflow could markedly decrease screening times, which would improve overall diagnostic processes.

Enhancing Brain Elasticity: Key Lifestyle Habits to Unlock Genius Potential at Any Age

The brain is a masterpiece, often referred to as the king organ, as it governs the entire body. When the brain ceases to function, it marks the end of an individual's vitality, essentially rendering them a "vegetable." This profound importance raises a crucial question: Are we adequately nurturing and caring for our brains? In today's fast-paced world, humans often subject their brains to relentless stress and negative impulses, leading to cognitive decline. However, enhancing brain elasticity can be remarkably simple by adopting specific daily habits. These habits not only pamper the brain but also make it sharper and stronger. Key factors in boosting brain capacity include maintaining optimal hydration, engaging in IQ-enhancing non-digital games like chess and Scrabble, solving logical math problems, regular exercise, and meditation. Additionally, incorporating fruits and vegetables into the diet, consuming foods rich in Omega-3 and DHA, ensuring 8 hours of sleep, reducing screen time, learning new languages, playing various musical instruments, and fostering a positive and resilient mindset are vital. One crucial yet often overlooked habit is regular reading. Reading stimulates the brain, improves concentration, enhances vocabulary, and fosters a deeper understanding of diverse subjects, all of which contribute to increased cognitive flexibility and brain elasticity. Another important factor is maintaining good gut health. Recent research has shown that good gut bacteria play a crucial role in increasing brain activity. The gut-brain axis, a complex communication network, connects the gut and brain, allowing gut bacteria to influence cognitive functions. Probiotics and a diet rich in fiber can enhance the diversity and health of gut microbiota, leading to improved brain function and mental health. This review explores how these lifestyle practices contribute to cognitive enhancement, potentially transforming ordinary individuals into geniuses. It posits that genius is not an inherent trait but a result of deliberate and consistent mental engagement and nurturing. By embracing these strategies, including the habit of regular reading and maintaining good gut health, individuals can significantly elevate their cognitive abilities and achieve exceptional intellectual growth.

Impact of Digital Media, School Problems, and Lifestyle Factors on Youth Psychosomatic Health: A Cross-Sectional Survey.

Post-pandemic psychosomatic complaints in children and adolescents have been underreported. This study investigated psychosomatic complaints in children and adolescents in Northern Italy in 2023, with the aim of identifying changes in predictors and vulnerable subgroups. Cross-sectional data representative of scholars from a northern Italian province were analyzed using the Health Behavior in School-aged Children (HBSC) checklist. The sum scores, count data, and dichotomized data were examined, and predictor effects were expressed using a linear regression model for the sum scores. Data from 4525 participants (aged 7-19 years, 50.5% girls) were analyzed. Psychosomatic symptoms remained unchanged after the pandemic. Significant gender differences were noted, especially in older age groups, with girls reporting more complaints. Factors such as children's health, digital media use, and school problems significantly influence psychosomatic outcomes. While migration background negatively affected girls' psychosomatic well-being, boys showed improvement through sports. The psychosomatic well-being of children and adolescents did not improve after the pandemic. These findings indicate the need for targeted interventions, improved health literacy, and ongoing monitoring to support the mental well-being of this vulnerable population. Reducing screen time remains a critical strategy for enhancing youth well-being.

Mindfulness programs for problematic usage ofthe internet: A systematic review and meta-analysis.

Problematic usage of the internet (PUI) is an umbrella term for a range of uncontrolled, excessive, and potentially harmful online behaviors. Recently, numerous studies have examined the potential of mindfulness programs (MPs) for reducing PUI. We conducted a comprehensive systematic review and meta-analysis in this emerging field. We searched eight databases from inception to October 18, 2022, with no language restrictions. We included randomized controlled trials (RCTs) and nonrandomized trials (NRTs). The primary outcome was change in self-reported PUI, the secondary outcome was change in screen time. Of 3,473 identified records, 19 RCTs and 20 NRTs with a total of 1,549 participants were included. Participation in an MP was associated with large reductions in PUI in between-group analysis in RCTs (k = 19; g = -1.67; 95% CI -2.15, -1.19) and in within-group pre-post analysis in all studies (k = 35; g = -1.67; 95% CI -1.99, -1.36). Screen time showed a medium reduction in within-group pre-post analysis (k = 10; g = -0.65; 95% CI -0.90, -0.41). The effects for PUI remained significant in a series of sensitivity analyses, such as excluding low quality studies, excluding outliers, adjusting for publication bias, or using follow-up data. Heterogeneity between studies was high and the overall quality of evidence was rated low. MPs are probably effective in reducing PUI and might be effective in reducing screen time. Shortcomings in the quality of evidence highlight the need for high-quality controlled trials with long-term follow-ups to confirm results.
