Associations between media parenting practices and early adolescent screen use.

To assess the prevalence of various media parenting practices and identify their associations with early adolescent screen time and problematic social media, video game, and mobile phone use. Cross-sectional data from Year 3 of the Adolescent Brain Cognitive Development (ABCD) Study (2019-2022) that included 10,048 adolescents (12-13 years, 48.3% female, 45.6% racial/ethnic minorities) in the US were analyzed using multiple linear regression analyses adjusting for potential confounders. Parent screen use, family mealtime screen use, and bedroom screen use were associated with greater adolescent screen time and problematic social media, video game, and mobile phone use. Parentaluse ofscreens to control behavior (e.g., as a reward or punishment) was associated with higher screen time and greater problematic video game use. Parental monitoring of screens was associated with lower screen time and less problematic social media and mobile phone use. Parental limit setting of screens was associated with lower screen time and less problematic social media, video game, and mobile phone use. Parent screen use, mealtime screen use, and bedroom screen use were associated with higher adolescent problematic screen use and could be limited in a family media use plan. Parental monitoring and limiting of screen time are associated with less problematic screen use. Although the American Academy of Pediatrics provides guidance for screen use for children 5-18 years, there is a paucity of evidence-based guidance for media parenting practices, specifically for early adolescents. In a diverse sample of 10,048 early adolescents across the US, we found cross-sectional associations between parent, mealtime, and bedroom screen use and higher adolescent problematic screen use. Parental monitoring and limiting of adolescent screen time were cross-sectionally associated with less problematic screen use in our analytic sample and may be incorporated into a family media use plan.

Screen use in transgender and gender-questioning adolescents: Findings from the Adolescent Brain Cognitive Development (ABCD) Study

ObjectiveTo assess the association between transgender or gender-questioning identity and screen use (recreational screen time and problematic screen use) in a demographically diverse national sample of early adolescents in the U.S. MethodsWe analyzed cross-sectional data from Year 3 of the Adolescent Brain Cognitive DevelopmentSM Study (ABCD Study®, N = 9859, 2019–2021, mostly 12–13-years-old). Multiple linear regression analyses estimated the associations between transgender or questioning gender identity and screen time, as well as problematic use of video games, social media, and mobile phones, adjusting for confounders. ResultsIn a sample of 9859 adolescents (48.8% female, 47.6% racial/ethnic minority, 1.0% transgender, 1.1% gender-questioning), transgender adolescents reported 4.51 (95% CI 1.17–7.85) more hours of total daily recreational screen time including more time on television/movies, video games, texting, social media, and the internet, compared to cisgender adolescents. Gender-questioning adolescents reported 3.41 (95% CI 1.16–5.67) more hours of total daily recreational screen time compared to cisgender adolescents. Transgender identification and questioning one’s gender identity was associated with higher problematic social media, video game, and mobile phone use, compared to cisgender identification. ConclusionsTransgender and gender-questioning adolescents spend a disproportionate amount of time engaging in screen-based activities and have more problematic use across social media, video game, and mobile phone platforms.

Differential associations between Quantity, content, and context of screen time, and Children's health-related quality of life: A two-wave study

Existing literature suggests that lengthy durations of screen time (ST) are associated with lower levels of health-related quality of life (HRQoL) and other negative outcomes in children. Nonetheless, the current available evidence largely relies on cross-sectional studies. In addition, data on the content and context (parent–child co-use and solitary use) of ST are scarce. We set out to conduct a one-year, two-wave longitudinal study to investigate the association between exposure to different types of ST and HRQoL among primary school children in Hong Kong, from 2021 to 2022. A population representative random sample (N = 1428) participated in the study. Results from pooled ordinary least squares regressions showed children's ST duration was significantly associated with worse HRQoL (β = −1.101, p < 0.0001). However, interactions of ST content and context, including parent–child co-use × TV viewing (β = 1.305, p < 0.0001), parent–child co-use × video gaming (β = 0.280, p < 0.0001), solitary use × video gaming (β = 0.198, p < 0.0001), and solitary use × social media use (β = 0.454, p < 0.0001) were significantly associated with better HRQoL. Our findings suggest that increased overall durations of ST are associated with worse HRQoL in children, but this association is impacted by the types of ST content and context.

Screen Time Use and Ultra-Processed Food Consumption in Adolescents: A Focus Group Qualitative Study

BackgroundSedentary lifestyles and ultra-processed food (UPF) consumption contribute to a high prevalence of overweight and obesity among adolescents. Screen time may be associated with higher UPF consumption and affect eating behaviors substantially. ObjectiveThe aim of this study was to explore adolescents’ perceptions, attitudes, and motivations concerning the consumption of UPF when using screens; investigate their perceived educational needs regarding nutrition; and explore their knowledge about UPF. DesignThis was a qualitative study using focus groups. Participants/settingFour focus groups with 30 adolescents aged 12 to 16 years at a Spanish high school were recruited in May 2022. Participants were chosen using purposive sampling based on a theoretical saturation criterion. AnalysesFocus group discussions were audio-recorded, transcribed verbatim, and analyzed using inductive thematic analysis. ResultsThree themes emerged from the thematic analysis. Participants explained that most of their meals were eaten in front of screens. They confirmed more consumption of UPF at breakfast, as mid-afternoon snacks, on weekends, and during their main meals when alone. Participants reported that the high consumption of UPF during social gatherings was related to its easy availability, convenience, and palatability. Adolescents expressed that eating in front of screens and exposure to UPF advertising led to compulsive and impulsive consumption of these products. They described UPF as addictive and unhealthy. Although participants had little awareness of UPF health effects, they expressed interest in learning about healthy eating habits. Parental attitudes toward food were considered by the participants as relevant in establishing their eating behaviors. ConclusionsLoneliness, social gatherings, and parental attitudes toward UPF consumption emerged as important influences on adolescents’ dietary behaviors in front of screens. In addition, availability, palatability, and exposure to advertising were key factors reported to influence adolescents’ UPF consumption in front of screens. Addressing these influences through nutritional and educational interventions, as well as regulating the adolescent obesogenic environment and managing screen time could help modulate these effects.

Childhood internalizing, externalizing and attention symptoms predict changes in social and nonsocial screen time.

While accumulating research has tested the hypothesis that screen time causes psychiatric symptoms in children, less attention has been paid to the hypothesis that children with psychiatric symptoms change their patterns of screen time and digital media use. We aimed to test whether children with psychiatric symptoms subsequently change their patterns of screen time and digital media use. N = 9,066 children primarily aged 9-10 in the Adolescent Brain Cognitive Development Study at baseline and 1-year later. Psychiatric symptoms included internalizing, attention, and externalizing symptoms. Screen time was measured as ordinally defined weekday and weekend time on social and nonsocial [e.g., YouTube] digital media). Models assessed psychiatric symptoms as predictors of screen time, and screen time as predictors of psychiatric symptoms, controlled for baseline measures of each, sex, age, race/ethnicity, and income. Children with psychiatric symptoms spent more time on non-social media one year later compared with peers. Considering total psychiatric problems, clinical levels of problems predicted higher levels of weekday (OR = 1.22, 95% CI 1.22-1.23) and weekend (OR = 1.10, 95% CI 1.09-1.11) nonsocial screen time. For nearly all analyses of psychiatric symptoms predicting screen time, associations were highest for a non-social screen time outcome rather than a social screen time outcome (Highest OR = 1.65, 95% CI 1.63-1.67, clinical rule breaking predicting weekday nonsocial screen time). Comparable magnitude associations were observed for social and nonsocial media use predicting future psychiatric symptoms, suggesting bidirectionality. Children with psychiatric symptoms have different subsequent media use patterns, including higher rates of subsequent nonsocial engagement. Ensuring that ongoing data collection and analysis efforts attend to temporality and transitions in the relation between media use and psychiatric symptoms will accelerate progress in the field.

The digital citizenship of children with autism: Challenges, considerations and educational needs of paediatric practitioners

AbstractThis exploratory study examined paediatric practitioners' challenges and considerations when they support caregivers and children with autism regarding children's screen use. Current research often focuses on the problematic use of screen time among children with autism. No clear strategies or recommendations for clinicians to support the beneficial use of screens exist yet in the field. Participants in the study were 15 experienced paediatric practitioners invited to participate in semistructured interviews that were analysed using summative content analysis. Practitioners expressed the urgent need for accessible and valuable educational resources to guide digital citizenship and screen time use for their clients with autism. This exploratory study provides an initial roadmap for the educational needs of paediatric practitioners supporting positive screen use and digital citizenship of autistic children.

Executive dysfunction as a possible mediator for the association between excessive screen time and problematic behaviors in preschoolers.

Excessive screen time in children is a growing concern for parents and healthcare providers worldwide because it frequently leads to behavioral problems. Although executive dysfunction is proposed to be one of the contributing factors to maladaptive behaviors, little is known about the link between screen time and behaviors. This study aimed to identify whether executive dysfunction contributes to the negative behaviors of children exposed to excessive screen time. A cross-sectional study was conducted on preschool-aged children from public and private schools in Chiang Mai, Thailand. The parents/guardians of each child completed the questionnaires regarding clinical characteristics and screen time use, the Behavior Rating Inventory for Executive Function-Preschool (BRIEF-P), and the Strengths and Difficulties Questionnaire (SDQ). Children with more than one hour of media exposure per day were considered to have excessive screen time. Multivariable Gaussian regression was analyzed to compare the BRIEF-P and SDQ scores between the excessive and appropriate screen time groups. Causal mediation analysis was performed to examine the effects of total screen time on increasing behavioral problems with executive functioning as a mediator. A total of 1,126 preschoolers were included in the analyses. After controlling for age, sex, socioeconomic status, and maternal education, the excessive screen time group had significantly higher BRIEF-P global executive composite score than the appropriate screen time group (mean difference of global executive composite score = 1.49, 95% CI [0.12, 2.86], and p = 0.033). Concurrently, there were significant differences in externalizing behavior subscales and SDQ total difficulties scores between the excessive and appropriate screen time groups (mean difference of total difficulties score = 0.90, 95% CI [0.29, 1.50], and p = 0.004). A significant average causal mediation effect (ACME) of screen time on behavioral problems mediated through executive functioning was β = 0.28, 95% CI [0.13-0.44], which was more than half of the total effect (54.9%, 95% CI [37.4-100%]). The current study suggests that the increase in behavioral issues in preschoolers might be partly explained by the direct effect of excessive screen time and the mediating effect of impaired executive functioning. Our results may raise concerns about the necessity to limit screen time and monitor for executive function deficits and behavioral problems in young children with high screen time.

School Closures and the Impact on Screen Time and Behavior during the Pandemic

Objective: The objective of the study is to examine the impact of school closures on recreational screen time, emotional, and behavioral functioning of school-going children and adolescents during the imposition of social containment measures and school closure in India. Methodology: The survey utilized a Google Form that was sent to parents of children aged 6–14 years through e-mails and social media platforms. Parents were asked to report on the child’s duration of recreational screen time and whether the child’s overall behavioral functioning had changed since the school closures. The child’s emotional and behavioral functioning was assessed by the Strength and Difficulties Questionnaire (SDQ). The scores on the SDQ and screen time use were compared by overall parental behavioral rating to identify the areas of concerns for children whose functioning was reported to have worsened after the closing of schools. Results: The mean recreational screen time was reported to be 2.65 h (standard deviation = 1.89). A significantly higher proportion of children whose behavior worsened after school closures, relative to those who improved or were same, had scores in the abnormal range of functioning on three of the subscales of SDQ including emotional problems (χ ² = 29.03, P = 0.0001), hyperactivity/inattention (χ² = 24.67, P = 0.0001), conduct problems (χ² = 22.01, P = 0.0001), and overall total SDQ score (χ² = 41.20, P = 0.0001). Conclusions: Interventions should be aimed at encouraging outdoor physical activity while respecting government restrictions, healthy routines, pursuing hobbies, and promoting responsible use of electronic devices during the pandemic and crisis recovery period.

IJCM_355A: Sleep Hygiene Among Higher Secondary School Students in Mandya City – A Cross Sectional Study

Background: Sleep is a basic biological process and is essential for good physical well-being. Cognitive development and emotional functioning of a child also depend on good sleep quality. Adolescents tend to have poor sleep quality because of high academic pressure, excessive mobile phone screen time, interpersonal relationship etc. Adolescents with poor sleep are prone for depression, anxiety, inattention, substance abuse, impaired academic performance and suicidal thoughts and behaviours. Sleep hygiene is an essential component of sleep, encompassing behavioural and environmental factors intended to promote healthy sleep. Good sleep hygiene is a predictor of sleep quality. There is a scanty knowledge and there are few studies done regarding sleep hygiene which would help to understand the factors responsible for poor sleep quality. So this study is done with the following objectives Objectives: 1) To assess quality of sleep among higher secondary school going students in Mandya city 2) To assess and correlate sleep hygiene practice with sleep quality. 3) To correlate the effect of internet addiction and sleep quality 4) To correlate the effect of Academic performance and sleep quality. Methodology: This cross-sectional study was conducted among school going students in two higher secondary schools in Mandya city between Oct 2023 to December 2023 using SQS scale, ASHS questionnaire, IAT score, APS score. Descriptive statistics like frequency, proportion, mean and standard deviation has been used. Results: Mean SQS score, ASHS score, IAT total score, APS score were calculated. Correlation between SQS score and ASHS score and IAT score, APS score were done. Conclusion: More health education should be provided for the students regarding sleep hygiene, the screen time use reduction and its effects on sleep, academic performance also should be explained.

The Relationship Between Children’s Screen Time and the Time They Spend Engaging in Play: An Exploratory Study

ABSTRACT Introduction Play is a critical daily occupation that facilitates children’s learning of essential life skills. However, with the growing use of, and accessibility to, online-linked devices, children are engaging more and more in screen-time linked activities and less time in non-technology play. Therefore, it is crucial to understand the influence of children’s screen-time use on their play patterns. This study aims to explore the relationship between school-age children’s screen time and their engagement and participation in play occupations. Methods Twenty-six pairs of parents and children were recruited to complete the Children’s Play Scale (CPS), parent and child versions of the Children’s Screen Time Use Report (CSTUR), and the Children’s Perceptions of Their Play (CPTP). Data were analyzed using Spearman’s rho correlations and linear regressions with bootstrapping. Results Two regression models found that weekday social screen time accounted for 30.7% of the total variance (p = .002) of social play while weekend educational screen time, weekday interactive screen time, and weekday passive screen time together accounted for 55.6% of the total variance (p < .001) of active play. Conclusion The study findings provide evidence that a relationship exists between school-aged children’s screen time and play engagement and participation. Further research is recommended on this topic.

The Effect of Outdoor Play, Physical Activity, and Screen Time Use on the Emotional Wellbeing of Children and Youth during a Health Crisis

Long-standing research has highlighted the critical role of physical and outdoor activities for children’s health and wellbeing. During the COVID-19 pandemic, children around the world experienced heightened stress and poor mental health, which coincided with a decrease in active play and increase in screen-based activities. This study examined how physical, outdoor, and screen-based activities impacted emotional wellbeing during the post-lockdown period of COVID-19. Caregiver proxy report of children’s activities and emotional wellbeing was collected from 190 caregivers through an online survey in February-April 2021. Overall, we observed low levels of physical and outdoor activities and high levels of screen activities in children, especially those aged 5 and older. Unadjusted models suggested that time spent in physical activity and online socializing predicted child wellbeing positively and negatively, respectively. However, only child age, parent-child co-play, parent stress, and family life satisfaction emerged as significant predictors of child wellbeing in the fully adjusted model. The findings facilitate a deeper understanding of children and youth’s outdoor engagement during the pandemic and highlight the critical role of parents and families in supporting children’s emotional wellbeing and healthy recreation under sustained stress and disruption.

Parental use of routines, setting limits, and child screen use during COVID-19: findings from a large Canadian cohort study

BackgroundAn increase in child screen time has been observed throughout the COVID-19 pandemic. Home environment and parenting practices have been associated with child screen time. The purpose of this study was to examine associations between parental use of routines, limit setting, and child screen time during the (COVID-19) pandemic to inform harm-reducing strategies to limit the potential harms ensued by excessive screen use.MethodsA cohort study was conducted in 700 healthy children (3,628 observations) aged 0–11 years though the TARGet Kids! COVID-19 Study of Children and Families in Toronto, Canada from May 2020-May 2021. The independent variables assessed were parent-reported use of routines and setting limits. Outcomes were parent-reported child daily screen time in minutes and whether the Canadian 24-Hour screen time guideline was met, defined as 0 for &amp;lt;1 years, 60 or less for 1–5 years, and 120 or less for &amp;gt;5 years. Linear and logistic mixed-effects models were fitted using repeated measures of independent variables and outcomes with a priori stratification by developmental stages (&amp;lt;3, 3–4.99, ≥5 years).ResultsA total of 700 children with 3,628 observations were included in this study [mean age = 5.5 (SD = 2.7, max = 11.9) years, female = 47.6%]. Mean change in child screen time before vs. during the pandemic was +51.1 min/day and level of parental use of routines and setting limits remained stable. Lower use of routines was associated with higher child screen time (β = 4.0 min; 95% CI: 0.9, 7.1; p = 0.01) in ages ≥5 years and lower odds of meeting the screen time guideline in ages &amp;lt;3 years and ≥5 years (OR = 0.59; 95% CI: 0.38, 0.88; p = 0.01; OR = 0.76; 95% CI: 0.67, 0.87; p &amp;lt; 0.01). Lower use of limit setting was associated with higher child screen time and lower odds of meeting the screen time guideline in ages ≥5 years (β = 3.8 min; 95% CI: 0.69, 6.48; p &amp;lt; 0.01; OR = 0.86; 95% CI: 0.78, 0.94; p &amp;lt; 0.01).ConclusionsLower parental use of routines and limits during the COVID-19 pandemic were associated with higher screen time and lower odds of meeting the screen time guideline among school-age children. Results may help inform strategies to promote healthy screen use in this age group.

Screen time and addictive use of gaming and social media in relation to health outcomes.

This study examined associations between screen time and addictive use (i.e., heavy involvement and negative consequences) of gaming and social media, and their independent effects on health outcomes. Survey data were collected from 2,265 participants (mean age = 21.57). Internet Gaming Disorder (IGD) and Social Media Disorder (SMD) were measured with the Gaming and Social Media Questionnaire (GSMQ-9), with separate measures for heavy involvement and negative consequences. Screen time was measured by weekly hours of gaming and social media. Assessed health outcomes were psychological problems, low self-concept, social problems, sleep problems, and sleep time. Screen time and addictive use were significantly associated for both gaming and social media, with associations being stronger for symptoms of heavy involvement compared to symptoms of negative consequences. However, despite significant associations, a substantial proportion of the participants with a high screen time did not meet any or just one symptom of addiction. More importantly, it was primarily negative consequences that had independent effects on health outcomes, except for sleep. High levels of heavy involvement in gaming, were even related to lower, not higher, levels of psychological problems. The present findings study show that screen time is a poor indicator of addictive use of gaming and social media. Given that it was primarily negative consequences of gaming or social media that had effects on health outcomes, our study also emphasizes the need to distinguish between different types of addictive use and to further examine the diagnostic validity of the nine IGD symptom criteria.

National Trends in the Prevalence of Screen Time and Its Association With Biopsychosocial Risk Factors Among Korean Adolescents, 2008–2021

PurposePrior studies suggested an increase in screen time among adolescents during the COVID-19 pandemic; however, due to limited sample size and a short-term observation period, these associations are inconclusive and inconsistent. Thus, we aimed to compare screen time during the pandemic and the long-term trend through a Korean large-scale and long-term study of one million adolescents. MethodsData from 2008 to 2021 on 913,191 Korean adolescents aged 12–18 years were obtained via a nationwide, large-scale, and serial study. We investigated the change of screen time use over time and the change in trend before and during the pandemic (2008–2019 vs. 2020–2021) by using weighted linear regression model with estimates of β-coefficients and 95% confidence intervals (CIs). Moreover, we analyzed the differences in vulnerability of biopsychosocial factor before and during the pandemic. ResultsA total of 913,191 adolescents were included in this analysis. During the pandemic, the overall screen time of Korean adolescents significantly increased compared to the expected based on the prepandemic period during the pre–COVID-19 period (weighted screen time before the pandemic [133.24 min/day; 95% CI, 132.08–134.40] vs. during the pandemic [303.66 min/day; 95% CI, 300.59–306.73]; βdiff 0.331; 95% CI, 0.311–0.351). Comparing before and during the pandemic, potential risk factors associated with screen exposure included female sex, sadness, suicidal thoughts, alcohol consumption, low educational level of parents, low level of vigorous physical activity, middle school students, and low household income. DiscussionThrough large-scale nationwide study, this study described the 14-year trend of screen time among Korean adolescents. In the era of COVID-19, the prevalence of screen exposure has been increasing more rapidly than before at the population level. Also, the pandemic amplified the differences in screen time across grade, sex, sadness, suicidal thoughts, smoking, alcohol consumption, education level of parents, physical activity, and household income groups.

Parents' Knowledge On, Attitude Toward, and Practice of Screen Time Exposure Regulation of Their Children Under Six Years of Age in Western Region, Saudi Arabia.

Children and teenagers spend a significant amount of time watching screens, which include cellphones, tablets, gaming consoles, televisions, and computers. Regulation of screen time exposure is a crucial matter to avoid the health drawbacks of prolonged screen exposure. Assessment of parents' knowledge, attitude, and practice of regulation screen exposure among their children under six years old in the western region of Saudi Arabia. A cross-sectional study was conducted on a convenience sample of 451 parents of under-six-year-old children in the western region of Saudi Arabia. Data were collected by using an online questionnaire, and a link to the survey was distributed to respondents via electronic platforms as well as to primary healthcare visitors. The data were analyzed using SPSS software. This study included 451 parents from the Saudi western region. Most of the participating parents were female (64.3%), aged 25-34 years (34.8%), married (86.0%), and had completed their university education (56.1%). This study found that 76.4% of parents had adequate knowledge, 73.1% had a positive attitude, and 69.8% had adequate practice of screen time regulation for their children under six years of age. Factors associated with their good knowledge include being married (p = 0.002), having government work (p = 0.020), having children who use mobile phones, and having children attend kindergarten (p <0.001) for each. Furthermore, highly educated parents showed more positive attitudes than others (p-value = 0.004). Finally, better practice of screen time regulation was noted among highly educated parents (p = 0.011), who had government jobs (p = 0.031), and children who went to kindergarten (p = 0.031) for their children. In this study, parents of under-six-year-old children possessed overall good knowledge and a positive attitude, but their actual practice of screen time regulation for their children was low, specifically in terms of parental supervision of the content that children watch, their care of children's regular exercise, and using devices as a method for motivating or punishing their children. Additionally, sociodemographic characteristics like education, occupation, and marital status played a role in this issue. Healthcare professionals such as pediatricians, family doctors, general practitioners, and others can caution parents of young children under six years old about the harmful consequences of excessive screen use. Further longitudinal research is needed to understand the long-term effects of screen time exposure among young children. From this study, further qualitative research would aid in a greater understanding of the impact of parental knowledge, attitude, and practice on their children's use of screen time.

The Influence of the Exposome in the Cutaneous Squamous Cell Carcinoma, a Multicenter Case-Control Study.

The concept of exposome refers to the total of harmful and beneficial environmental exposures that can help predict the organism's biological responses over time. Ultraviolet radiation (UVR) from sun exposure has been recognized as the main etiological agent of skin cancer, and squamous cell carcinoma (SCC) is one most commonly associated with chronic exposure. However, in recent years, evidence suggests that lifestyle, environmental pollution, and contaminants in water and food can have an influence. To study the relationship between SCC and sun exposure, pollution, stress, and lifestyle in a Spanish cohort. A multicenter case-control study was carried out in which 13 dermatologists from different regions of Spain recruited cases and controls between April 2020 and August 2022. The group of cases were patients diagnosed with SCC and, as a control group, people who attended Dermatology consultations as companions with no history of skin cancer. A total of 62 patients with SCC and 126 controls were included (62.9% males, median age 76.46 (10.1) and 33.3%, median age 55.7 (15), respectively). The SCC group had experienced more outside work than the controls (75% vs. 22.4%, p < 0.001), less recreational exposure (sunbathing, p = 0.05, and outdoor sports, p = 0.01), and a lower annual income (p = 0.01), with an increase in tobacco exposure (p < 0.001), without differences in other carcinogens, such as ionizing radiation or chemical exposure. The control group had a higher daily screentime use (p < 0.001) and practiced more relaxation activities (p = 0.03). A higher linolenic acid intake and lower coffee consumption were the only dietary variables associated with SCC (p < 0.05). Some chronic medications (anxiolytics, antidepressants, beta-blockers, statins, hydrochlorothiazide, ACE inhibitors, metformin, and omeprazole) were also statistically associated with SCC. Statistical significance for all aforementioned variables was maintained in the multivariate analysis (p < 0.05). The study found a significant association between SCC and multiple exposome-related factors in addition to chronic sun exposure in the Spanish population. Primary prevention strategies should target specific populations, such as outdoor workers promoting sun-safe behaviors and stress-reducing activities, in addition to adequate skin photoprotection in patients under certain medications associated with SCC.

How Early Digital Experience Shapes Young Brains During 0-12 Years: A Scoping Review

ABSTRACT Research Findings: Early digital experience (e.g. screen time and digital use) is believed to impact children’s brain development, functionally and structurally, but this impact has not been systematically reviewed. In this scoping review, we synthesized and evaluated 33 collected studies on children’s digital use (ages 0–12) and their associated brain development published between January 2000 and April 2023. The synthesis of the evidence revealed that (1) digital experience does have positive and negative impacts on children’s brains, structurally and functionally; (2) it could cause structural and functional changes in children’s frontal, parietal, temporal, and occipital lobes, brain connectivity, and brain networks; and the most vulnerable area is the prefrontal cortex and its associated executive function, and (3) early digital experience has both positive and negative impacts on children’s brain structure longitudinally. Practice or Policy: Educators and parents should be aware of the potential effects of digital experience on children’s brain development and provide appropriate guidance, mediation, and support for children’s digital use. Policymakers should establish and implement evidence-based policies and regulations to protect children’s digital well-being.

The impact of social media usage on lifestyle behaviors and health

AbstractIntroductionDespite the increasing popularity of social media, little research has been conducted on its impact on lifestyle behaviors and health outcomes among adults. This study aimed to investigate whether more frequent social media screen time use is associated with poorer lifestyle behaviors, overweight or obesity, and depressive symptoms. Additionally, this study examined the potential use of social media to positively influence health.MethodsAn anonymous one‐time survey was conducted among English‐speaking social media users aged 18–34 in Southern California. Self‐reported height and weight were used to calculate body mass index (BMI), and the Patient Health Questionnaire‐9 (PHQ‐9) was used to estimate the severity of depressive symptoms. A cumulative risk score for lifestyle behaviors was also tallied. Three focus groups were held with a subset of the survey population to gain insights on social media, lifestyle behaviors, and health. A mixed method analysis was used to analyze the data.ResultsThe survey data of 86 complete cases showed a positive correlation (r = 0.421; p &lt; 0.001; 95% confidence interval [CI] [0.223, 0.585]) among PHQ‐9 depression scores and negative correlation (r = −0.230; p = 0.033; 95% CI [−0.426, −0.12]) for BMI compared to actual social media screen time usage, respectively. However, social media screen time usage ≥3 h showed no association for either BMI, depressive symptoms, or cumulative risk score. Participants viewed social media as a “double‐edged sword,” providing benefits such as “connection” and “information sharing,” but also having a negative impact on mental health (theme 1). Participants also believed public health needs to take a more proactive role in using social media, while social media platforms should manage the “authenticity” of content and modify their “algorithms” to improve health and lifestyle practices (theme 2).ConclusionsThis study suggested that social media may have some protective benefits related to becoming overweight or obese as indicated by the focus group participants, but further research is needed on the relationship between social media screen time usage and adult mental health. Social media platforms may have the potential to promote positive lifestyle behaviors and improve health if used properly.

Socioeconomic Inequality in Screen Time, Phone, and Tablet Use among Iranian Adolescents: Results of A National Study.

Excessive screen time has been associated with a variety of negative health outcomes. We aimed to evaluate screen time and phone and tablet use in Iranian adolescents and their relation to the socioeconomic status of adolescents' families in 2018. This descriptive-analytical study was carried out on 10-12-year-old adolescents from Kurdistan, Fars, and Markazi provinces. Cluster sampling was used for sampling. Data were collected by completing demographic questionnaires, calculating the BMI of adolescents and phone and tablet use, screen time, and socioeconomic status of the families. We used linear and logistic regression to estimate the final model. The concentration index was used to measure inequality and the Oaxaca decomposition to examine the different determinants of the inequality. 1590 adolescents (52.58% boys) were enrolled in our study. Screen time activities were significantly higher in boys, older adolescents, higher BMIs, more educated mothers, and 35< year-old fathers (P < 0.05). The use of mobile phones and tablets was significantly higher among boys, ten-year-olds, families with four or fewer members, higher BMIs, adolescents with higher levels of parental education, and more educated mothers (P < 0.05). In addition, the concentration index for screen time activities (C = 0.083) and phone and tablet use (C = 0.536) showed that screen time and phone and tablet use activities were higher in adolescents with high socioeconomic status. Screen time, phone and tablet use were higher in adolescents with high socioeconomic status. Also, many other factors like gender, age, BMI, parents' education and age can affect screen time, phone and tablet use in adolescents.

Screen time in the development of cardiovascular diseases: A two-sample Mendelian randomization study

Background and aimsCoronary artery disease (CAD), heart failure (HF), and ischemic heart disease (IHD) are three common cardiovascular diseases that are closely associated with metabolic activity. The global incidence and prevalence of these conditions are on the rise, primarily due to unhealthy lifestyles, aging populations, and the increasing prevalence of obesity and diabetes. Excessive screen time has emerged as a potential risk factor for various adverse health outcomes, although limited research has explored its relationship with cardiovascular disease outcomes. Methods and resultsA Mendelian randomization (MR) study was conducted, employing exposure-associated genetic variants as instrumental variables to explore the causal relationship between screen time use and cardiovascular disease outcomes. Single nucleotide polymorphisms (SNPs) were utilized as pooled data for the genetic variable instrument, investigating the association between screen use duration and three types of cardiovascular diseases: coronary artery disease (CAD), heart failure (HF), and ischemic heart disease (IHD). Through the MR analysis, it was revealed that the use of mobile phones and TV screens exhibited a significant causal association with the occurrence of CAD, heart failure, and IHD. However, no significant association was observed between the use of computers and these three types of cardiovascular diseases. ConclusionOur study suggests that excessive screen time use is associated with the development of cardiovascular disease. However, it should be noted that the consequences of screen time can vary depending on the reasons and purposes for its use. Implementing reasonable control over screen time, particularly for entertainment purposes, holds promise as a potential approach to mitigating cardiovascular disease.
