Screen time trajectories and psychosocial well-being among Chinese adolescents: a longitudinal study

BackgroundWhile the association between screen time (ST) and psychosocial well-being has been extensively examined, limited studies have investigated the dynamic patterns of ST, and their impact on subsequent psychosocial well-being among adolescents. Therefore, this longitudinal study aimed to examine the association between ST trajectories and the subsequent psychosocial well-being among Chinese adolescents.MethodsData were drawn from the Longitudinal Study of Adolescents’ Mental and Behavioral Well-being Research (Registration No. ChiCTR1900022032). The final analysis included 1480 participants who completed baseline and two follow-up surveys. Standardized measures were employed to assess ST and multiple psychosocial well-being, including depressive symptoms, anxiety, externalizing problems, and coping style. Group-based trajectory modeling and generalized linear mixed models were performed.ResultsOver the two-year follow-up period, two distinct ST trajectories emerged: continued high (298 [20.1%]) and continued low (1182 [79.9%]). Compared with those in the continued low ST group, adolescents in the continued high group exhibited a higher likelihood of presenting depressive symptoms (β = 0.97, 95% CI = 0.43 ~ 1.50), anxiety symptoms (β = 0.29, 95% CI = 0.05 ~ 0.53), and emotional problems (β = 0.35, 95% CI = 0.22 ~ 0.48), and were less likely to demonstrate prosocial behavior or employ positive coping style. The stratified analysis demonstrated that the aforementioned associations only existed among female adolescents.ConclusionsPersistent high exposure to ST was associated with an increased odds of emotional problems and a decreased probability of engaging in prosocial behavior and positive coping style, with particularly noteworthy effects observed among female adolescents. These findings underscore the importance of reducing ST exposure to improve the psychological well-being of adolescents.

Screen exposure status and related factors in children with epilepsy

To understand the status of screen exposure in children with epilepsy and analyze the influencing factors for screen exposure time, providing a scientific basis for managing screen exposure in these children. A convenience sampling method was used to select 275 children with epilepsy from outpatient clinics or those undergoing 24-hour electroencephalogram monitoring at two tertiary hospitals in Jinan from March to June 2023. Their parents (fathers or mothers) completed a questionnaire to collect data on screen exposure, parental screen regulation behaviors, and related information about the children and their families. The Wilcoxon rank-sum test or the Kruskal-Wallis H test was used to conduct a univariate analysis of the average screen exposure time of children on school days and weekends, as well as the daily average screen exposure time. A multivariate logistic regression analysis was used to identify the risk factors for children whose screen exposure time exceeded the recommended guidelines (average screen exposure time on school days >1 hour or average on weekends >2 hours). The median screen exposure duration on school days was 40 minutes, while on weekends it was 120 minutes. Among the children studied, 23.1% (63/273) had average screen exposure time exceeding 1 hour on school days, and 42.5% (117/275) had average screen exposure time exceeding 2 hours on weekends. Four children experienced seizures while using screen devices. Multivariate logistic regression analysis indicated that using screen devices shortly before sleep, lower educational levels of parents, caregivers discussing screen content with children, and longer seizure durations in children were risk factors for exceeding recommended guidelines (P<0.05). Some children with epilepsy have a screen exposure time exceeding the recommended guidelines. A longer seizure duration, lower parental education levels, and permissive digital parenting are closely associated with children's screen exposure time exceeding the recommended guidelines. Families and children exhibiting these characteristics should be prioritized for attention and health education.

Screen Exposure in 4-Year-Old Children: Association with Development, Daily Habits, and Ultra-Processed Food Consumption.

This study aimed to investigate the association between child development, daily habits, and ultra-processed food consumption with screen exposure in 4-year-old children. A cross-sectional study was conducted using a questionnaire that included sociodemographic data, the child's daily habits, and screenings for child development and eating habits. The daily screen exposure time (cell phone, computer, television, and/or tablet) was measured in minutes and classified as inadequate if >60 min. We conducted bivariate analyses and a generalized linear model. Overall, 362 caregivers-children pairs were investigated. The average screen time per child was 120 min (IQR: 120), and most of the children (71%) showed inadequate screen time for the age group. The longest screen time was associated with the lowest score in child development (β = -0.03; p = 0.01), an increased habit of eating in front of screens (β = 0.34; p < 0.001), and the highest score of ultra-processed foods (UPFs) (β = 0.05; p = 0.001). The sample showed a high prevalence of inadequate screen time, and this has been associated with the lowest score in child development, an increased habit of eating in front of screens, and the highest score of UPFs.

Screen time and social media exposure in children and adolescents - the landscape

Abstract Dr. Cecilia Elias is a Public Health Consultant, collaborating with the Infant, Youth, Sexual and Reproductive Health Division at the Health Directorate General, in Lisbon, Portugal. Following on from John’s introduction, Cecilia will dig deeper into the impacts of the omnipresence of social media and phones in modern society. She will provide an overview of the harms and benefits for today’s youth. She will highlight data for example on impaired development of language, cognitive and social skills from screen exposure at young ages, and increased rates of depression, anxiety, self-harm, and school refusal among adolescents with problematic social media usage, including examples of significant outcomes. Exposure to disturbing and harmful content on social media platforms like TikTok and Instagram will be covered also.

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 3.00-6.97years) 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.

Does Screen Time Do More Damage in Boys Than Girls?

Background Technological progress, particularly accelerated by the recent pandemic, has led to the digitalization of many aspects of daily life. Consequently, children are increasingly exposed to screen time, raising concerns about its potential impact on early development. Methods Four separate questionnaires were developed for different age groups (12-18 months, 19-30 months, 31-48 months, and 49-72 months). Data were collected over a two-month period from three major pediatric facilities, and social media platforms were also utilized to reach participants. The total sample size consisted of 5,137 children. Results Exposure to active screen time was found to increase the risk of expressive language delay, with a significant correlation identified between early screen time exposure and expressive language delay. In the 12-18 months age group, the OR was 1.52 (p = 0.008, χ²(1) = 7.08, p = 0.008), while in the 19-30 months age group, the OR was 1.79 (p = 0.0002; χ²(1) = 14.30, p < 0.001). Conclusions This study provides significant insights into the complex relationship between screen time exposure and expressive language development in young children. Our findings reveal that early screen time exposure is associated with a higher risk of expressive language delay. The data suggest that children aged 12-30 months are especially vulnerable. However, we cannot definitively state that the amount of average daily screen time is significantly changing the outcome. Conversely, we also found that a lack of screen time exposure may be associated with an increased risk of language delay in children aged 31-48 months, highlighting the nuanced role of screen time in child development. Parental supervision is a critical factor; however, our study indicates that higher levels of supervision do not consistently mitigate the risks associated with screen time across all age groups. Further research is warranted to explore the underlying factors contributing to the observed differences in susceptibility to expressive language delay among genders and to examine the long-term impacts of early screen exposure. By understanding these dynamics, we can better support children's developmental needs in an increasingly screen-saturated environment.

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

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. 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. 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. 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.

Sleep Quality in School-Aged Children: The Role of Environmental Factors and Screen Time

Sleep plays a vital role in the optimal functioning of our body and is crucial for overall well-being. However, many parents are unaware of the negative consequences of sleep deprivation in children. This study examines factors affecting sleep in children and their correlation with screen time. The aim is to evaluate the relationship between screen time and environmental factors impacting sleep quality among school-aged children.A cross-sectional observational study was conducted on children aged 6 to 12 years. Sleep quality was assessed using a 22-item, pre-validated, parent-administered Children’s Sleep Habits Questionnaire (CSHQ). Contributing factors, including a screen time questionnaire, were gathered from parents. Children with pre-existing sleep disorders, neurobehavioral disorders, and chronic illnesses were excluded. A CSHQ score above 41 was considered abnormal, indicating a sleep problem. Data were analyzed using the Chi-square test with SPSS version 20.0.In this study, 40.3% of children experienced sleep disturbances. The total mean sleep score was 39.56 ± 14.84, with private school children showing greater disruptions (41.78 ± 12.96) compared to public school children (37.14 ± 16.33; p = 0.001). Significant correlations were found between sleep quality, screen time exposure, and environmental factors such as lower socio-economic status, bed sharing, and room sharing.This study highlights that both excessive screen time and adverse environmental conditions negatively impact children's sleep quality. Efforts to increase awareness among parents, educators, and healthcare providers are needed to reduce sleep disturbances.

Study of impact of screen exposure time on behavioural and growth parameters in urban Indian children

Background: The American academy of paediatrics (AAP) recommends 2 hours of screen time (ST) daily for children and teenagers, with no exposure for those under 2 years old. However, research shows children often exceed these limits, leading to behavioural issues, obesity, and unhealthy eating habits. This study aimed to evaluate STs impact on behaviour, growth, and eating habits in children aged 1.5 to 8 years. Methods: This cross sectional, observational study, conducted in the paediatric department, enrolled 401 children aged 1.5 to 8 years. Demographic details, weight, height, and BMI of the children were recorded. Parents provided information of their child's ST, screens at home, their own ST, and child’s eating habits. Behavioural parameters were evaluated using the child behaviour checklist (CBCL). Internalizing and Externalizing behaviours were also recorded in which internalizing factors comprised of anxious and somatic behaviours, while externalizing factors encompassed aggression and rule-breaking behaviours. Data analysis was performed using SPSS V.23. Results: In our study, 401 children were enrolled, comprising 233 females (58.10%) and 168 males (41.90%). Out of 401, 201 (50.12%) exceeded 2 hours of ST, while 159 (39.65%) had 1 to 2 hours, and only 41 (10.22%) had less than 1 hour. There was a strong significant association between children's ST and their internalizing (p=0.00034), externalizing (p=0.009), withdrawn (p=0.001), rule breaking (p=0.03) and aggressive (p&lt;0.01) behaviour. Additionally, children weight had a positive correlation between ST and BMI (p=0.015). Conclusions: Excessive ST use correlates well with higher BMIs, behavioural issues like withdrawal, somatic complaints, rule-breaking, aggression. Urgent interventions are needed to reduce ST and promote healthier lifestyles among children, involving parents, caregivers, and policymakers.Top of Form

The impact of screen time on children’s well-being development: a scoping review

In the era of digitalisation, working parents today rely more than ever on electronic gadgets as digital babysitters and device-led playtime to entertain their children. The study suggests that parents and their interactions with the home environment may contribute to shaping children’s screen time. However, many struggle to keep up with the immense variety of mobile applications easily downloaded online. Thus, long screen time exposure inhibits children’s ability to engage actively in physical activities as well as affects children’s well-being development. This scoping review aims to identify parental perceptions of children’s exposure to screens for a long period of time and how screen time affects children’s well-being. Five databases, including Scopus, Web of Science (WOS), Bielefeld Academic Search Engine (BASE), Education Resources Information Center (ERIC), and ScienceDirect, were used in this research. In the initial identification stage, 218 articles were identified from the mentioned databases above. However, there were only 81 articles found to be assessed for eligibility. A total of 34 articles are eligible for analysis and reference after the exclusion and inclusion process for data collection. The findings show that the increased exposure to screens raised concerns about potential negative effects on children’s emotions and behaviour.

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 Impact of Speech and Language Delays on the Early Grade Readers in Preschool Children at Karachi: lessons for the literacy instructors

This study investigates the impact of speech and language delays on early-grade reading abilities in preschool children in Karachi, Pakistan, considering variables such as screen time exposure, pragmatic language development, speech skills, language disorders/delays, social communication, language acquisition, and late talkers. It aims to provide a better understanding of the prevalence of these delays among children aged 3 to 7 years and assess the effectiveness of early identification and intervention strategies. The research addresses four key questions: the prevalence of speech and language delays, the efficacy of early detection for functional literacy, the short-term and long-term outcomes of universal screening, and the influence of socioeconomic factors on early-grade reading effectiveness. The study employs a cross-sectional design to evaluate prevalence and effectiveness. Participants include children from diverse socio-economic backgrounds, and data collection methods encompass adapted screening tools, interviews with parents and educators, socio-economic surveys, and follow-up assessments. ANOVA and Thematic analyses are used to determine the screening tools' prevalence, sensitivity, specificity, and predictive values, along with insights from stakeholder feedback.

Associations of activity, sedentary and sleep behaviors with oral health indictors in children and adolescents: a cross-sectional analysis

BackgroundThe purpose of this study was to examine the associations of physical activity (PA), recreational screen time, and sleep with indicators of poor oral health in youth.MethodsParticipants were children and adolescents whose parents completed the 2022 National Survey of Children’s Health (N = 34,342; 49% female; Mean age = 11.9 +/- 3.5 years). The dependent variables were three binary response items that indicated the presence of toothaches, bleeding gums, and cavities within the previous 12 months. Independent variables were three items indicating the weekly frequency of 60 min of PA, hours of recreational screen time, and hours of weeknight sleep. Relationships between variables were examined using double-selection logistic regression with demographic, dietary, oral hygiene, and dental service covariates selected using the plug-in method of the least absolute shrinkage and selection operator.ResultsCompared to zero days of PA, 4–6 days of PA per week was associated with 30% lower odds of bleeding gums (p = 0.021). Compared to less than 1 h of recreational screen time, 2 h or more hours of recreational screen time were associated with a 1.26 to 1.62 times higher odds of cavities (p < 0.01). Compared to 5 h or less of sleep, 7 to 10 h of sleep was associated with 47–61% lower odds of bleeding gums and 31–47% lower odds of cavities (p < 0.01). Secondary analyses indicated that at least 2 of the movement behavior recommendations had to have been adhered to for positive associations with indicators of oral health to be observed. For toothaches, bleeding gums, and cavities, meeting 2 or 3 recommendations was associated with lower odds of poor oral health; whereas adhering to only one recommendation was not.ConclusionChildren with higher PA and sleep durations had improved oral health indicators and children with longer periods of screen time exposure had poorer oral health indicators. Our findings recommend adhering to multiple movement behavior recommendations to achieve improvements in oral health indicators.

The association between screen time exposure, parent depression, and development of social communication skills among preschool children in Qassim Region

BackgroundScreen exposure among children continues to increase worldwide. It has negative effects on children of developmental age, including obesity, poor attention, sleep disorders, vision problems, language delays, and deficits in communication skills. It has been reported that parental depression is associated with both increased screen time for children and poor function and skills in children. However, other studies have reported no association between screen time and parental depression.Research methodologyA cross-sectional study was conducted using a convenience sample of 340 parents of 4- to 6-year-old children in the Qassim Region of Saudi Arabia. Data were collected from the primary health care vaccination clinic by contacting parents of children aged 4 to 6 years to fill out the Social Communication Questionnaire (SCQ) for the child and the Patient Health Questionnaire-9 (PHQ9) for the parents.Research resultsWe conducted a regression analysis to assess the influence of screen time exposure on social communication skills (SCQ score). The results of this study indicated that there was no significant effect observed (B = 0.283, P > 0.05), indicating that a positive correlation between screen time usage and SCQ score may not apply to the entire population. Conversely, we discovered a crucial link between screen time exposure and parental depression (PHQ), as it displayed noteworthy impact values (B = 1.136, P < 0.05), indicating an affirmative correlation between them. In addition, our results also indicated apparent positive associations between parental depression and SCQ scores (B = 0.229, P < 0.05).ConclusionOur findings revealed that there was a significant association between parental depression and both screen time exposure and SCQ score, while there was no correlation between screen time exposure and SCQ score.

Screen Time and its Relation to Toddlers’ Development

Abstract Background Screen-time or digital-screen exposure is the duration of time spent by the individual in using electronic/digital media like television (TV), smartphone, tablet or computer. Even background television exposure has been shown to impact development by reducing the amount and quality of interactions between parents and children. Studies showed that while babies do not absorb content from TV, it can catch and hold their attention. Aim of the Work The aim of the current study was to determine the effect of screen time on different developmental aspects of toddlers. Patients and Methods This was a cross sectional observational study that was conducted in the outpatients’ and Neurodevelopment Clinics, Children’s Hospital, Faculty of Medicine, Ain Shams University on 83 toddlers aged from 1 year to 3 years old who were exposed to screens for a longer duration than the recommended according to the American Academy of Paediatrics (AAP) guidelines. Of 13 months’ time frame, total duration of screen exposure was calculated in minutes/day and was correlated to the composite scores of Bayley scales of infants’ and toddlers’ development third edition. Results A significant negative correlations were found between duration of screen time exposure and all Bayley scales (cognitive, language and motor) composite scores and language scale is more affected. Conclusion The results of this study supported the directional association between screen time and child development. Parents and all the society should be educated about the hazards of screen time exposure on infants and toddlers’ development.

The importance of mother-child interaction on smart device usage and behavior outcomes among toddlers: a longitudinal study

BackgroundIn recent years, smart devices have become an integral part of daily life. However, longitudinal studies, particularly those regarding the relationship between toddlers’ smart device usage and behavioral outcomes, are limited. Understanding the impact of parent–child interactions on this relationship is crucial for enhancing toddlers’ developmental outcomes. Accordingly, this study examined the influence of early screen time and media content exposure on toddlers’ behaviors, as well as the positive effects of mother–child interactions on this influence.MethodsWe used relevant data related to 277 children born between November 2016 and July 2020 and who were part of an ongoing prospective follow-up study conducted across five hospitals in Taipei City, Taiwan. We analyzed (1) data from maternal reports regarding children’s behavior by using the Child Behavior Checklist (for ages 11/2–5 years), (2) assessments of mother–child interactions by using the Brigance Parent–Child Interactions Scale, and (3) self-reported parental data covering the first 3 postpartum years. Statistical analyses involved group-based trajectory modeling and multiple linear regression.ResultsA considerable increase in screen time between the ages of 1 and 3 years was associated with less favorable behavioral outcomes at age 3. These outcomes included somatic complaints [adjusted beta coefficient (aβ) = 2.17, 95% confidence interval (CI) = 0.39–3.95, p-value = 0.01], withdrawal (aβ = 2.42, 95% CI = 0.15–4.69, p-value = 0.04), and aggressive behavior (aβ = 6.53, 95% CI = 0.25–12.81, p-value = 0.04). This association was particularly evident among children with lower levels of mother–child interaction. Nevertheless, positive mother–child interactions mitigated most of the adverse effects. Additionally, increased exposure to games and cartoons was associated with poorer behavioral outcomes in all children except for those experiencing positive mother–child interactions.ConclusionEarly mother–child interactions play a crucial role in mitigating the risk of behavioral problems in toddlers who spend prolonged periods looking at screens and who are frequently exposed to game and cartoon content.

The association between screen time exposure and myopia in children and adolescents: a meta-analysis

ObjectiveThis study aimed to systematically review epidemiological evidence on associations between screen time exposure and myopia in children and adolescents, and to quantitatively evaluate summary effect estimates from existing literature.MethodThere were three online databases including PubMed, Embase, and Web of Science, for epidemiological studies on screen time exposure and myopia published before June 1, 2023. The risk of bias was assessed by the Newcastle Ottawa Scale (NOS) checklist. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the correlation between screen time exposure and myopia using random or fixed-effect models by exposure type (categorical/continuous). We also performed subgroup analysis by screen device type, study quality, geographic region, and research period.ResultsWe searched 7,571 records from three databases and identified 19 eligible studies, including 14 high-quality studies and 5 moderate-quality studies. Meta-analyses suggested that there was a statistically significant correlation between screen time (high vs. low) and myopia. The pooled ORs with 95%CIs were respectively 2.24 (1.47–3.42) for cross-sectional studies, and 2.39 (2.07–2.76) for cohort studies. We also found a significant association between continuous exposure to screen time (per 1 h/d increase) and myopia in cohort studies. The pooled ORs with 95%CIs were 1.07 (1.01–1.13). In subgroup analysis stratified by screen device type in cross-sectional studies, screen time exposures from computers (categorical: OR = 8.19, 95%CI: 4.78–14.04; continuous: OR = 1.22, 95%CI: 1.10–1.35) and televisions (categorical: OR = 1.46, 95%CI: 1.02–2.10) were associated with myopia, while smartphones were not. Although publication bias was detected, the pooled results did not show significant changes after adjustment using the trim and fill method.ConclusionOur findings support that screen time exposure was significantly associated with myopia in children and adolescents. Notably, screen time exposure from computers may have the most significant impact on myopia.

Prevalence and Predictors of Screen Time Exposure in Young Children: A Descriptive, Facility Based Study

Abstract Background: Excessive screen time exposure amongst children has become a global concern due to its detrimental effects on health and development. Understanding the prevalence and associated risk factors is crucial for designing effective interventions. This study aimed to estimate screen exposure time and identify associated risk factors amongst children aged 6 months–6 years in Akola district, India. Materials and Methods: A descriptive facility based study was conducted in Akola district, utilising data collected from two outpatient departments. Data were collected through interviews with mothers using a pre-designed questionnaire. Sociodemographic factors and screen time habits were assessed. Statistical analyses, including multivariate regression, were performed to identify significant predictors of screen exposure time. Results: Of the 417 children included in the study, 53.7% had excess screen exposure, with an average screen time of 1.6 h. Infants under 1 year had notably high exposure rates (95.1%). Maternal and paternal education, maternal occupation and child’s behaviour (throwing tantrums) were significantly associated with screen exposure time. Conclusions: The findings highlight the urgent need for public health interventions to address excessive screen time amongst young children in Akola district of India. Efforts should focus on raising parental awareness, promoting healthier screen time practices and encouraging outdoor activities. Further research is recommended to assess the impact of interventions and the evolving screen time patterns, particularly in light of the COVID-19 pandemic.

Effects of electronic screen exposure time on hypertensive disorders in pregnancy: a retrospective cohort study

BackgroundWe previously conducted a case-control study and found that exposure to electronic screen before nocturnal sleep was associated with hypertensive disorders in pregnancy (HDP). Hence, we carried out this cohort study aiming to identify the effects of screen exposure time on the incidence rate and severity of HDP.MethodsA retrospective cohort study was conducted from January 2022 and July 2022 from three hospitals in Wuxi and Changzhou cities. A total of 732 women were recruited and the information included socio-demographic characteristics, screen exposure and outcomes. Generalized estimating equations and binary non-conditional logistic models were applied to multivariate analysis, calculating the odds ratios (ORs) and 95% confidence intervals (CIs) of screen exposure time.ResultsThe duration order of total screen time was smartphone > computer > television, while the duration order of screen time before nocturnal sleep was smartphone > television > computer. Multivariate analyses showed that the susceptibility of HDP among women who exposed to television before nocturnal sleep was 81.5% percent higher than those not exposed (P = 0.018, OR[95%CI] = 1.815[1.106–2.981]). In addition, total daily exposure time of television in the third trimester of pregnancy significantly increased the severity of HDP (P = 0.021, OR[95%CI] = 3.641[1.213–10.927]).ConclusionsBased on this preliminary study, we would suggest that pregnant women do not watch television before nocturnal sleep. While in the third trimester of pregnancy, total exposure time of television should be limited. Investigations from other areas and experimental studies should be conducted to verify the conclusion.

Screen Time Exposure and Domain-Specific Working Memory in Young Adults.

Introduction With technology advancing across all fields, the utility of digital screens is increasing among all age groups for various purposes.Research indicates that while digital technology presents clear advantages, prolonged exposure can have detrimental effects on various aspects of health, behavior, emotions, and cognitive functions like attention and working memory. A crucial cognitive process for learning and information processing which is working memory, can be affected by factors includingscreen time. Studies have found that the impact of screen time on working memory can be negative, positive, or show no discernible relationship. However, earlier investigations are limited to smartphone use as screen time exposure and further to only active screen time. As there is a dearth of studies in the Indian context and young adults are more exposed to screen time, it is important to investigate along these lines. Hence, the present study aimed to investigate the impact of active and passive screen time exposure on modality-specific working memory in young adults. Methods Seventy-sevenneurotypical individuals aged between 18 and 22 years were recruited. The study utilized auditory and visual reverse digit span tasks and the Corsi-backward task to measure working memory span. Screen time data of the participants were collected through a self-administered 18-item questionnaire covering active and background screen time domains. Results and discussion The present study concluded that only active screen time has a significant effect onvisual reverse digit span and supports the notion of the visual superiority effect against an auditory superior effect as suggested by earlier findings. The preliminary findings of correlation observed exclusively within the visual domain in this study could be attributed to the potential impact of screen time exposure (active screen time and textual content). Screen usage demands effective switching between various visual stimuli and ongoing updates of information in memory. Nonetheless, interpreting this explanation and generalization requires caution, given the low ecological validity of the task employed in the study. Future investigations should aim to collect screen time exposure data more objectively, perhaps through online tracking techniques. Furthermore, it would be prudent to expand the correlation analysis to include other cognitive processes and populations.
