Prevalence and Associated Factors of Internet Addiction Among Male Students of Jubail University College, Saudi Arabia

This study aims to determine the associated factors and prevalence of Internet addiction among Jubail University College – Male Branch students. Descriptive cross-sectional method was applied. 171 students participated. Self-administered survey questionnaire was the data-gathering instrument. Young's Internet Addiction Test was used to determine the level of internet usage. Factors associated with high internet consumption are accessibility, boredom, isolation, and extreme weather condition. Covid-19 pandemic changed the way respondents consume internet. It also changed the respondents' sleeping pattern and increases the average internet usage per day. Though the internet played a vital role during Covid-19 pandemic, it also increases the dependency of students on it. Higher number of moderate level internet addiction has been found among respondents. Therefore, it is encouraged that JUC should design a program to address the current situation.

Physical activity level, screen time and sleep habits in Chilean adolescents, during quarantine by COVID-19

Objective: to determine the level of physical activity (NAF), screen time (TP) and sleep habits (HS) in Chilean adolescents, during the COVID-19 quarantine. Methodology: descriptive and correlational study with a sample of 196 adolescents from different regions of Chile. Results: In general, the most active students did not exceed the PD recommendations and reported higher values of sleep quality and total score compared to those who did not meet both. Conclusion: the study indicates that, under a quarantine context, the variables are more altered in the female gender, in addition, the need to jointly analyze and monitor the NAF, TP and HS is evident to avoid disorders related to the health of the males.

Effect of COVID-19 lockdown on sleep behavior and screen exposure time: An observational study among Indian school children

Lockdown is an important measure that has been globally adopted to reduce the spread of the contagious disease caused by SARS CoV-2. The imposed schedule and confinement led to extensive use of digital media and rise in sedentary activity drastically. The escalated duration of screen exposure causes disruption in sleep behavior. An online survey was conducted to comprehend the effect of lockdown on sleep behavior and screen exposure time on school children. Screen exposure time involved with various electronic gadgets was also analyzed. It was observed that the social jet lag and sleep debt were significantly less during lockdown than before it. Inertia during lockdown significantly increased. The difference between screen exposure time on weekdays before lockdown and weekends during lockdown was identified to be the highest. Three clusters based on sleep behavior and duration of screen time were identified of which Cluster 2 revealed simultaneous existence of high sleep duration and screen time. These baseline data on sleep parameters and duration of exposure to the screen will help us in devising approaches to mitigate the evident disruption this unprecedented phase has brought about.

Coronavirus Label-Free Immunosensor: Preliminary Results

Real-time detection of airborne infection agents present in human breath and environmental airways, such as the human respiratory Coronavirus, is important for public health. For this, a model label-free immunosensor, based on multi-walled nanotubes (MWNT)-based screen-printed graphite electrodes (SPEs), was proposed and studied. For sensing applications, MWNTs have many advantages such as small size with larger surface area, excellent electron transfer promoting ability when used for antibody immobilization, with retention of its selectivity for potential immunosensors development. In order to verify the selectivity of the selected primary antibody (anti-CoV 229E antibody) and the effective immunocomplex formation (antigen-antibody), an in-depth voltammetric characterization of MWNT-SPEs interface was carried out during the multistep fabrication of CoV immunosensor using [Fe(CN)6]3−/4− as an electroactive probe.After that, the analytical robustness of the performances of these immunosensing platforms was estimated and verified. Indeed, a nanomolar range detection limit (180 TCID50/mL)g/mL) with excellent reproducibility (RSD% = 8%) was obtained. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

The Relationship Between Screen Time and Symptom Severity in Children with ADHD during COVID-19 Lockdown.

OBJECTIVES: To investigate the relationship between screen time and symptom severity in children with ADHD during the COVID-19 lockdown. METHODS: Caregivers of children with ADHD aged 7 to 16 years completed the screen time questionnaire and ADHD rating scales of the SNAP-IV-Thai version during and after the COVID-19 lockdown. The correlation between screen time and ADHD scores was assessed. RESULTS: Of the 90 children, aged 11.31 ± 2.29 years, enrolled, 74.4% were male, 64.4% were in primary school, and 73% had electronic screens in their bedrooms. After adjusting with other factors, recreational screen time, both on weekdays and on weekend days, were positively correlated with ADHD scores (both inattention and hyperactive/impulsive scores). Studying screen time, on the other hand, was not associated with ADHD symptom severity. Compared to during the lockdown, studying screen time decreased after the lockdown, but recreational screen time and ADHD scores were not changed. CONCLUSION: Increasing recreational screen time was associated with worsening ADHD symptoms.

Relationship Between Screen Time and Dry Eye Symptoms During the COVID-19 Pandemic in the Pediatric Population of the Western Region of Saudi Arabia.

Objective To measure the prevalence of dry eye disease (DED) and study the relationship between screen time and dry eye symptoms in the pediatric population during the coronavirus disease 2019 (COVID-19) pandemic using the Ocular Surface Disease Index (OSDI) questionnaire. Methods In this descriptive, observational, cross-sectional study, our survey included the pediatric population, ages 1 to 18 years, of both genders, who attended outpatient clinics of two main hospitals in Jeddah, Saudi Arabia. Collected data included age, gender, dry eye symptoms, and common DED risk factors, followed by the Ocular Surface Disease Index (OSDI) questionnaire, which consists of 12 items graded on a five-point scale (0 = never to 4 = all the time). Results A total of 329 pediatric participants were included, with more than half of the participants (56.1%) males and 58.5% aged 12-18 years. The most frequently reported symptoms (reported as often or always) were decreased vision (23.0%) and itchy eyes (22.1%). Environmental factors have an effect on developing DED symptoms, as some participants (21.8%) have reported being uncomfortable in windy weather and 15.8% have reported this in places with air conditioners. Based on the OSDI diagnostic criteria, 250 (76.1%) participants had DED. Furthermore, in terms of severity, 44 (13.3%) participants had mild DED, 62 (18.8%) participants had moderate DED, and 145 (43.9%) participants had severe DED. We found that prolonged exposure to mobile screens for two to three hours or four hours or more was associated with a higher DED incidence compared to those exposed for shorter periods. Older age categories were more likely to experience DED (80.8% and 78.2% in age categories 12-18 and 7-12, respectively, versus 57.6% in the youngest age category (p = 0.001)). Additionally, DED was independently associated with participants with a previous history of eyeglasses prescription and those experiencing dry eyes while using electronic devices. Conclusion Since many children use electronic devices for education and entertainment, we found that symptoms of DED due to prolonged screen time have increased among the pediatric population during the COVID-19 pandemic. Therefore, awareness efforts should be directed to reduce the rate of controllable risk factors like personal computer use. In addition, educational campaigns are warranted to provide all possible preventive measures against DED, especially to children with uncontrollable risk factors for developing DED.

Correlation between screen time and psychosomatic symptoms in children during COVID-19 pandemic-related lockdown.

Background: This study was planned to estimate the effect of lockdown on psychosomatic problems and sleep of children and their association with screen the time during the lockdown. Methods: A cross-sectional study was conducted among 1-12-year-old children at a tertiary care hospital in South India. A pre-validated questionnaire with 20 related questions was disseminated through pediatric OPD, telemedicine service, and social media to eligible parents. Results: A total of 278 children aged 1-12 years with a mean (SD) age of 6.92 (3.01) years were studied. Most under 5-year-oldchildren had screen time of ≤2 hours/day, whereas 58.16% of children between 5 and 12 years spent >4 hours/day (P < 0.000). A significant proportion of participants aged 5-12 years had vision problems (P = 0.019), whereas under 5-year-old children had significant associated behavioral changes (P = 0.016) and sleep problems (P = 0.043). Conclusion: Behavioral and sleep problems were significantly high and correlated with an increase in screen time among under 5-year-old children. Vision problems were more in 5-12-year-old children.

Preschool children's screen time during the COVID-19 pandemic: associations with family characteristics and children's anxiety/withdrawal and approaches to learning.

With schools closed due to the COVID-19, many children have been exposed to media devices for learning and entertainment, raising concerns over excessive screen time for young children. The current study examined how preschoolers' screen time was associated with their family characteristics and anxiety/withdrawal and approaches to learning during the COVID-19 pandemic. Participants were 764 caregivers of 3- to 6-year-old children (mean age = 59.07 months, SD = 12.28 months; 403 boys and 361 girls) from nine preschools in Wuhan, China, where the pandemic started. The effects of family characteristics on children's screen time during the pandemic outbreak and the associations between screen time and children's anxiety/withdrawal and approaches to learning were examined using path analysis. The results showed that children who spent more time on interactive screen use (e.g., playing with tablets) showed higher levels of anxiety/withdrawal and fewer positive learning behaviors. Unexpectedly, children who spent more time on noninteractive screen use (e.g., watching TV) showed lower levels of anxiety/withdrawal. Additionally, children's screen time was related to family characteristics: children living in more chaotic families with fewer screen time restrictions spent more time on screen use after the pandemic outbreak. The findings suggest that young children's frequent use of interactive screens, such as tablets and smartphones, might be harmful to their learning and wellbeing during the pandemic. To mitigate the potential negative effects, it is essential to manage the screen time of preschoolers by establishing rules for their interactive screen use and improving the household routines related to the overall screen use.

Associations of active and passive smartphone use with measures of youth mental health during the COVID-19 pandemic.

Smartphone use provides a significant amount of screen-time for youth, and there have been growing concerns regarding its impact on their mental health. While time spent in a passive manner on the device is frequently considered deleterious, more active engagement with the phone might be protective for mental health. Recent developments in mobile sensing technology provide a unique opportunity to examine behaviour in a naturalistic manner. The present study sought to investigate, in a sample of 451 individuals (mean age 20.97 years old, 83% female), whether the amount of time spent on the device, an indicator of passive smartphone use, would be associated with worse mental health in youth and whether an active form of smartphone use, namely frequent checking of the device, would be associated with better outcomes. The findings highlight that overall time spent on the smartphone was associated with more pronounced internalizing and externalizing symptoms in youth, while the number of unlocks was associated with fewer internalizing symptoms. For externalizing symptoms, there was also a significant interaction between the two types of smartphone use observed. Using objective measures, our results suggest interventions targeting passive smartphone use may contribute to improving the mental health of youth.

Discrepancies Between Self-reported and Objectively Measured Smartphone Screen Time: Before and During Lockdown.

Screen time shows higher health risks compared to other types of sedentary behaviors. A lockdown may simultaneously increase screen time, reduce physical activity (PA), and change time perception. Our goal was to compare self-reported against objectively measured smartphone screen time (SST) in a sample of active and inactive Portuguese adults before and during a social lockdown. This study was a cross-sectional analysis with 211 Portuguese adults (57.8% males), aged 25.2 ± 8.5 years, from two cohorts, one before the social lockdown and the other during the lockdown. SST was self-reported (SR-SST) and objectively measured using a smartphone (OM-SST). PA was self-reported. Linear regressions were performed to determine the association between SR-SST and OM-SST. A Bland and Altman analysis was used to assess agreement. Independent T-tests were performed for comparisons between cohorts and paired sample T-tests for comparisons within each cohort. The cohort assessed during the lockdown showed a higher SST than the cohort assessed before the lockdown (OM-SST; p < 0.001 and SR-SST; p = 0.009). Before the lockdown, there was no difference between SR-SST and OM-SST (p = 0.100). However, during the social lockdown, although the agreement between SR-SST and OM-SST was good (ICC = 0.72), participants systematically underestimated their SST by ~ 71 min/day (p < 0.001), and this underestimation was higher in inactive participants (~ 85 min/day) than in active individuals (~ 49 min/day). The general population needs to be aware of the benefits of limiting screen time, especially during periods of societal modifications, such as a generalized lockdown. There was a tendency to underestimate SST, meaning a lack of awareness of the actual time spent in this potentially deleterious behavior. This underestimation was more pronounced during the lockdown period and for the inactive participants, thus posing a greater health risk. The findings from this investigation entail relevant information for policy makers to delineate strategies for reducing population screen time from a preventive health perspective.

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

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

High screen time and internalizing and externalizing behaviours among children aged 3 to 14 years during the COVID-19 pandemic in France.

Children's screen time increased as a result of the COVID-19 pandemic. In the summer of 2021, we explored the association between high screen time over a period of one year since May 2020 and behavioural problems among children and adolescents. The data were derived from the French EpiCov cohort study, collected in spring 2020, autumn 2020, and spring 2021. Participants (N = 1089) responded to online or telephone interviews about one of their children aged 3 to 14 years. Screen time was categorized as high if the daily mean screen time exceeded recommendations at each collection time. The Strengths and Difficulties Questionnaire (SDQ) was completed by parents to identify internalizing (emotional or peer problems) and externalizing (conduct problems or hyperactivity/inattention) behaviours in their children. Among the 1,089 children, 561 (51.5%) were girls, the average age was 8.6 years (SD 3.7). Internalizing behaviours: High screen time was not associated with internalizing behaviours (OR [95% CI] 1.20 [0.90-1.59]) or emotional symptoms (1.00 [0.71-1.41]) while it was associated with peer problems (1.42 [1.04-1.95]). Externalizing behaviours: High screen time was associated with externalizing problems (1.63 [1.01-2.63]) and conduct problems (1.91 [1.15-3.22]) only among older children aged 11 to 14 years. No association with hyperactivity/inattention was found. In a French cohort, exploration of persistent high screen time in the first year of the pandemic and behaviour difficulties in Summer 2021 resulted in mixed findings according to behaviour's type and children's age. These mixed findings warrant further investigation into screen type and leisure/school screen use to enhance future pandemic responses appropriate for children.

Prospective associations between child screen time and parenting stress and later inattention symptoms in preschoolers during the COVID-19 pandemic.

Introduction: Child attention skills are critical for supporting self-regulation abilities, especially during the first years of life. On the other hand, inattention symptoms in preschoolers have been associated with poor school readiness, literacy skills and academic achievement. Previous research has linked excessive screen time with increased inattention symptoms in early childhood. However, most research has only focused on TV exposure and did not investigate this association during the COVID-19 pandemic. This atypical context has increased screen time in children worldwide, including preschoolers. We hypothesize that higher levels of child screen media and parenting stress at age 3.5 will be associated with higher child inattention symptoms at age 4.5. Method: This study draws on participants followed longitudinally over the span of 2-years for an investigation of Canadian preschoolers' screen media use during the pandemic (N = 315, 2020). A follow-up with this sample was completed in 2021 (N = 264). Results: Analyses using multiple linear regression, revealed a positive association between child screen time at age 3.5 and inattention symptoms at 4.5 years. Parental stress was also positively associated with child inattention symptoms. Associations were observed above individual (child age, inhibitory control, and sex) and family (parent education and family income) characteristics. Discussion: These results confirmed our hypothesis and highlight that preschooler screen use and parenting stress may undermine attentional skills. Since attention is a crucial component for children development, behavior and academic outcomes, our study reinforces the importance for parents of adopting healthy media habits.

Paediatricians' awareness of Canadian screen time guidelines, perception of screen time use, and counselling during the COVID-19 pandemic

Objectives Paediatricians are essential in guiding families on screen time use as digital media becomes increasingly prevalent. While this has been highlighted through the COVID-19 pandemic there is no literature on paediatricians' awareness of Canadian screen time guidelines, or perception of these guidelines during this time. The aim of this study was to assess pediatricians' knowledge, attitudes, and comfort with the Canadian Paediatric Society's (CPS) screen time guidelines, specifically during the COVID-19 pandemic. Methods Our survey was developed by a paediatric resident and paediatric endocrinologist, reviewed by local experts, and sent electronically to members of the CPS Community and Developmental Paediatrics sections. Results All 53 respondents were aware of current CPS screen time guidelines, and the majority self-reported fair to excellent knowledge of guidelines for both age groups (<5 years and school-aged children/adolescents). Over 80% noticed increased screen use during the pandemic, and 98% were somewhat or very concerned about screen use and their patients' health and well-being. Pediatricians reported concerns about associations between increased screen time with worsening behaviour, mental health concerns, obesity, and sedentary lifestyle. The greatest barrier to reducing screen time was perceived insufficient motivation or support from caregivers/families. Conclusions Responding Canadian paediatricians are knowledgeable and comfortable with current screen time guidelines in Canada. Despite this, there is increasing concern with health outcomes associated with screen use. These results highlight paediatricians' important role in counselling patients and may encourage further local advocacy and public education around screen use and associated health risks in children.

Sleep quality as a mediator of the relationship between screen time and negative emotions among Chinese college freshmen.

College freshmen are special populations facing great challenges in adapting to the brand new environment, and their lifestyle and emotional states are worthy of attention. Especially during the COVID-19 pandemic, their screen time and prevalence of negative emotions were significantly increased, but few studies have focused on such situation of college freshmen and illustrated relevant mechanisms. Thus, based on a sample of Chinese college freshmen during the COVID-19 pandemic, the current study aimed to investigate the association between their screen time and negative emotions (depression, anxiety and stress), and further explore the mediating effects of sleep quality. Data from 2,014 college freshmen was analyzed. The screen time was self-reported by participants using predesigned questionnaires. The Pittsburgh Sleep Quality Index (PSQI) and Chinese Version of Depression Anxiety and Stress Scale-21 (DASS-21) were used to assess sleep quality and emotional states, respectively. The mediation analysis was conducted to examine the meditation effect. Results indicated that participants with negative emotions tended to have longer daily screen time and worse sleep quality, sleep quality partially mediated the association between screen time and negative emotions.The critical role of sleep quality and related intervention measures should be recognized and implemented.

Mental Wellbeing among Children with Cancer during COVID-19 Pandemic in Indonesia: A Cross-sectional Study

Introduction Coronavirus disease 2019 (COVID-19) has affected both physical and mental aspect of people worldwide, especially the high-risk group such as pediatric cancer patients. Children with cancer were considered both clinically and mentally vulnerable during this pandemic. They were also affected by the self- isolation, quarantine, and social distancing policy taken as a respond to public threat. Objectives To evaluate the impact of social distancing and health protocol during COVID-19 on the mental health profile of children with cancer in Indonesia. Methods A cross-sectional study evaluating the mental health of children with cancer during COVID-19 pandemic was conducted in Cipto Mangunkusumo Hospital, Jakarta, Indonesia from June to September 2020. An online questionnaire was used to collect demographics of parents and children, children's Strength and Difficulties Questionnaire ( SDQ) score, and parents' Self-Reporting Questionnaire (SRQ). SDQ score consists of five subscales, including the emotional symptoms, conduct problems, hyperactivity, peer relationships problems and prosocial behavior. Cancer types were grouped into retinoblastoma, nonretinoblastoma (other solid tumors), and leukemia. Results There were 156 valid responses, consisting of 42 patients with retinoblastoma, 34 patients with nonretinoblastoma ( other solid tumors), and 80 patients with leukemia. Pandemic-related lifestyle changes did not significantly impact emotional or behavioral problems. Children with normal total SDQ (odds ratio [OR]: 473, p = 0.001) and emotional scores (OR: 3.19, p = 0.07) had parents with normal SRQ scores (<6). Leukemia patients with shorter diagnosis period had worse hyperactivity score ( p = 0.01). On the contrary, leukemia inpatients had better prosocial scores than outpatients (p = 0.03). More bilateral retinoblastoma patients (p = 0.04) with longer duration of cancer diagnosis (p = 0.03) faced peer problems.

SCREEN-BASED ACTIVITIES AMONG CHILDREN IN CROATIA: A MEDIA DIARY APPROACH

This research has two objectives: 1) examine the average daily time of screen-based activities (SBAs), the most used devices, types of SBAs, and reasons for SBAs use in children;and 2) examine differences in these aspects of SBAs regarding the age of children in Croatia during the COVID-19 pandemic. The data came from 60 children's paper-and-pencil media diaries. Children on average spend more time during the day in SBAs than recommended by the literature (up to 1.5 or 2 hours). Older children spend more time in SBAs compared to younger children during the workweek. The most popular devices among children were TVs and smartphones, regardless of age. The most frequent types of children's SBAs were watching content and playing, but watching was more prevalent among younger children and playing among older children during the workweek. The most common reason for SBAs was to have fun, regardless of the children's age. All conclusions mainly apply to children from middle- to upper-socioeconomic- class families and the specific period of the COVID-19 pandemic.

Person Detection Based Adaptive Video Synthesis: A Fusion Framework for Ultra HD Panorama and Green Screen Videos

The past two years have witnessed the increasing prevalence of metaverse, while the COVID-19 pandemic has accelerated the formation of a non-contact culture. Under this circumstance, virtual reality once again attracts the public attention. Panorama video, as one of the most important forms of virtual reality, provides users with excellent immersion experience. This paper has proposed a fusion framework for Ultra HD panorama videos and green screen videos. In this framework, panorama videos are set as the virtual background layer on which the user-defined real foreground layer of portrait obtained by green screen matting is superimposed. During video fusion process, the portrait size is adaptively determined by parameters provided by a person detection algorithm running on panorama videos. Therefore, a more natural video synthesis result can be achieved, and presented on a head-mounted display or a flat screen device to provide an indistinguishable visual experience to the users. © 2022 IEEE.
