Reducing Screen Time Research Articles

Screen time and childhood attention deficit hyperactivity disorder: a meta-analysis.

The association between screen time and attention deficit hyperactivity disorder (ADHD) has been controversial. This study sheds light on the contentious correlation between screen time and ADHD. Until August 2022, electronic searches of the PubMed, Embase, and Web of Science databases were carried out. The combined effect value odds ratios (OR) and 95 % confidence interval (95 % CI) were calculated forthe meta-analysis using Stata 12.0. There were 81,234children in the nine studies that made up this meta-analysis which included 28,997 children with ADHDand 52,237 healthy controls. When compared withthe screen time <2 h/d, theOR (95 % CI) value of screen timeand ADHD in the screentime≥2 h/d group was 1.51 (1.20-1.90). Based on the current meta-analysis results, our study found a positive correlation between screen time and the risk of ADHD. Excessive screen exposure may significantly contribute to the development of ADHD in children. Therefore, it is necessary to reduce screen time per day in children to prevent the occurrence of ADHD.

Longitudinal associations between different types of screen use and depression and anxiety symptoms in adolescents.

Evidence examining the longitudinal associations between different types of screen behaviours and mental health among adolescents is limited. The present study examined the association between five types of screen behaviours and symptoms of anxiety and depression one year later. This study also assessed how changes in screen time were associated with changes in anxiety and depressive symptoms and whether the observed relationships were moderated by sex. Longitudinal data of 17,174 students in grades 9-12 (53.5% females; mean age: 15.1 ± 0.9 years) attending high schools in Canada from two waves (year 6: 2017/18, year 7: 2018/19) of the COMPASS study were analyzed. Leisure screen time and mental health measures were self-reported. To test if the associations between screen time and anxiety, and depression vary by sex, two-way interactions were examined for sex. Analyses accounted for school clustering, race/ethnicity, sex, age, income, body mass index z-score, and previous year anxiety and depression symptoms. There were significant longitudinal associations between time spent on each type of screen and subsequent anxiety and depression symptoms. The strength of the associations varied by type of screen behaviour. Interaction analysis indicated a sex difference for television viewing and anxiety and depression symptoms, and internet surfing and anxiety symptoms. A dose-response relationship was observed between phone talking and anxiety symptoms. Beta estimates indicated that an increase in screen duration was associated with a further increase in anxiety and depression symptoms. Higher screen time was longitudinally associated with higher anxiety and depression symptoms at one-year follow-up in adolescents. Time-change associations between screen usage and depressive and anxiety symptoms were observed. Also, associations differed based on sex and screen type, whereby greater increases in screen use predicted greater emotional distress. Findings from this prospective analysis suggest that screen time is an important determinant of anxiety and depressive symptoms among adolescents. Future studies are recommended to help inform programs promoting screen time reduction with a goal to enhance adolescents' mental health.

Investigation of sleep quality and musculoskeletal pain of university students during the pandemic period

Background/Aim: The transition to distance education due to the coronavirus-19 restrictions changed the routines of university students, and physical activity and sleep status were affected due to increased computer screen use. Determining the factors affecting the sleep quality and musculoskeletal pain of university students during the pandemic period will guide the measures that can be taken to address these changes. The aim of this study was to investigate sleep quality and musculoskeletal pain of university students during the pandemic. Our research asked, “What are the factors affecting sleep quality during the pandemic period and does a difference between the musculoskeletal pain of those with good and bad sleep quality exist?”&#x0D; Methods: University students receiving distance education were included in this cross-sectional study. Students’ demographic characteristics, exercise habits, daily use of smart mobile devices were questioned via an online form. The Pittsburgh Sleep Quality Index was used to evaluate sleep quality, and the Cornell Musculoskeletal Discomfort Questionnaire was used to evaluate musculoskeletal pain. Sleep quality status based on regular exercise and daily mobile device usage time were compared. In addition, the musculoskeletal discomforts of the participants with good or bad sleep quality were compared.&#x0D; Results: Two-hundred twenty-one university students were included in the study (187 female, 34 male). Sleep quality was better in those who exercised regularly (P=0.005). Subjective sleep quality and sleep latency scores were better for those who used smart mobile devices less than 5 h a day (P=0.002 and P=0.018, respectively). Those with good sleep quality had less musculoskeletal discomfort (P&lt;0.001).&#x0D; Conclusion: The findings of our study showed that increased physical inactivity and smart mobile device use during the distance education period negatively affect sleep quality. Since those with poor sleep quality have more musculoskeletal pain, we think that preventive measures, such as reducing screen time and inactivity, should be taken in distance education students to prevent health problems that may be associated with poor sleep status.

Understanding Accelerated Summer Body Mass Index Gain by Tracking Changes in Children's Height, Weight, and Body Mass Index Throughout the Year.

Background: Drivers of summer body mass index (BMI) gain in children remain unclear. The Circadian and Circannual Rhythm Model (CCRM) posits summer BMI gain is biologically driven, while the Structured Days Hypothesis (SDH) proposes it is driven by reduced structure. Objectives: Identify the mechanisms driving children's seasonal BMI gain through the CCRM and SDH. Methods: Children's (N = 147, mean age = 8.2 years) height and weight were measured monthly during the school year, and once in summer (July-August). BMI z-score (zBMI) was calculated using CDC growth charts. Behaviors were measured once per season. Mixed methods regression estimated monthly percent change in children's height (%HΔ), weight (%WΔ), and monthly zBMI for school year vs. summer vacation, seasonally, and during school months with no breaks vs. school months with a break ≥1 week. Results: School year vs. summer vacation analyses showed accelerations in children's %WΔ (Δ = 0.9, Standard Error (SE) = 0.1 vs. Δ = 1.4, SE = 0.1) and zBMI (Δ = -0.01, SE = 0.01 vs. Δ = 0.04, SE = 0.3) during summer vacation, but %HΔ remained relatively constant during summer vacation compared with school (Δ = 0.3, SE = 0.0 vs. Δ = 0.4, SE = 0.1). Seasonal analyses showed summer had the greatest %WΔ (Δ = 1.8, SE = 0.4) and zBMI change (Δ = 0.05, SE = 0.03) while %HΔ was relatively constant across seasons. Compared with school months without a break, months with a break showed higher %WΔ (Δ = 0.7, SE = 0.1 vs. Δ = 1.6, SE = 0.2) and zBMI change (Δ = -0.03, SE = 0.01 vs. Δ = 0.04, SE = 0.01), but %HΔ was constant (Δ = 0.4, SE = 0.0 vs. Δ = 0.3, SE = 0.1). Fluctuations in sleep timing and screen time may explain these changes. Conclusions: Evidence for both the CCRM and SDH was identified but the SDH may more fully explain BMI gain. Interventions targeting consistent sleep and reduced screen time during breaks from school may be warranted no matter the season.

A Program for Parents’ Screen Time Reduction for Preschool Children: A Quasi-experimental Study

Excessive screen time affects the development and health outcomes among children. This quasi-experimental study examined the effects of the newly developed Parents’ Screen Time Reduction for Preschool Children Program, a training program for parents’ planned behaviors and the screen time reduction of their children. The participants were dyads of parents and preschool children aged 2-5 years, where the child’s screen time was more than one hour per day. Sixty-seven parents were recruited from two childcare centers in a province in northeast Thailand, comprising 35 in the experimental group and 32 in the control group. Instruments to measure study outcomes focused on parents’ attitudes, subjective norms, perceived behavioral control, and intentions, and the distal result was behaviors. For children, the outcome was screen time reduction. Data analyses were descriptive statistics, chi-square, independent t-test, Mann-Whitney U test, and generalized estimating equations. The findings revealed that the children’s screen time in the experimental group decreased significantly more at one week and two months after the completion of the intervention than that of the control group. The mean scores of parents’ attitudes and parents’ behaviors in the experimental group were significantly more positive higher than those in the controlgroup immediately after the intervention; the mean score of parents’ perceived behavior control was significantly higher than that of the control group two months after the intervention. Nurses and teachers can use this program among parents to perform appropriate screen time behaviors to promote development and health outcomes among children. However, further testing of the program using randomized controlled trials is required before widespread use in practice.

Brazilian Immigrant Parents’ Preferences for Content and Intervention Modalities for the Design of a Family-Based Intervention to Promote Their Preschool-Age Children’s Healthful Energy Balance-Related Behaviors

Brazilians are a rapidly growing ethnic immigrant population in the United States (U.S.), and there is a lack of childhood obesity prevention interventions addressing the needs of Brazilian preschool-age children. Using the family ecological model (FEM) as a guide, this developmental cross-sectional study assessed the preferences (content, intervention modality, and language) of 52 individual Brazilian immigrant parents (27 mothers, 25 fathers) for a family-based intervention to promote healthful energy balance-related behaviors (EBRB). Overall, 85% or more of parents reported being interested or very interested in content related to five of the seven assessed EBRBs (increasing fruits and vegetables, reducing unhealthy foods and sugar-sweetened beverages, increasing physical activity, and reducing screen time). Parent-preferred intervention modalities were group sessions delivered by community health workers (CHWs, 86.5%), email (84.6%), and messaging (78.8%), with most parents (71.2%) indicating a preference for content in Portuguese. Interventions integrating multiple components, such as group sessions offered by CHWs and text messaging using SMS and WhatsApp, should be considered. Future steps for intervention development should include investigating different communication channels and their integration into a culturally and linguistically tailored family-based intervention designed to promote healthful EBRBs of preschool-age children in Brazilian families living in the U.S.

Physical education, muscle strengthening exercise, sport participation and their associations with screen time in adolescents.

Physical activity (PA) has been suggested to reduce screen time. This study aimed to explore the associations of physical education (PE), muscle-strengthening exercise (MSE), and sport participation with screen time. A multi-cluster sampling design was used to select 13,677 school-attending adolescents that participated in the Youth Risk Behavior Surveillance 2019 survey. Adolescents self-reported their frequency of PE attendance, participations in MSE, sport participation and hours for screen time. Additionally, participants provided demographic information including sex, age, race, grade, and weight status. Collectively, there were beneficial associations between participating in MSE for 4 (OR = 1.31, CI: 1.02-1.68), 5 (OR = 1.65, CI: 1.31-2.08), 6 (OR = 2.23, CI: 1.47-3.36), 7 (OR = 1.62, CI: 1.30-2.01) days and video or computer game hours. Similarly, beneficial associations between participating in 1 team sport (OR = 1.23, CI: 1.06-1.42), 2 team sports (OR = 1.61, CI: 1.33-1.95), 3 or more team sports (OR = 1.45, CI: 1.16-1.83) and video or computer game hours were observed. Participating in 1 team sport (OR = 1.27, CI: 1.08-1.48), 2 teams sport (OR = 1.41, CI: 1.09-1.82), 3 or more team sport (OR = 1.40, CI: 1.03-1.90) also increased the odds for meeting guidelines for television viewing hours. Only 2 days of PE attendance (OR = 1.44, CI: 1.14-1.81) was significantly associated with video or computer game hours. The promotion of sports participation appears to be an important component for reducing excess screen time in adolescents. Further, MSE may have beneficial effects on reducing time spent on the computer and playing video games.

Lifestyle Elements for Improving Mental and Physical Health in Japanese University Students: Subjective Sleep Quality is a Common Key Factor.

This study aimed to reveal the key lifestyle elements that improve physical and mental health in university students by focusing on physical activity, nutrition, and sleep. This cross-sectional study was conducted between October 2021 and December 2021. The participants were 290 first-year students (mean age, 18.63 ± .63years; age range, 18 to 23; 198 female). The outcomes were daily step counts measured using accelerometers, dietary intake by nutrient category, sleep duration, subjective sleep quality, exercise frequency and duration by exercise type, screen time, depression level, and subjective fatigue by body part. Depression and subjective eye fatigue represent mental and physical health outcomes. Subjective sleep quality predicted depression (β = -1.22, P < .001) and eye fatigue (β = -.23, P < .01) in the path analysis. Participants with higher subjective sleep quality performed more frequent aerobic exercise (P < .01), longer session times of physical relaxation exercise (P < .05), and shorter screen time (P < .05). Subjective sleep quality could be a key factor for high mental and physical health. Furthermore, performing aerobic and relaxation exercises and reducing screen time are important for improving the subjective sleep quality.

Reduction in Social Media Usage Produces Improvements in Physical Health and Wellbeing: An RCT

Social media usage has increased over recent years and has been associated with negative effects on health and wellbeing. This study explored whether reducing smartphone screentime would improve health and wellbeing. Fifty students completed a battery of questionnaires regarding their health, immune function, loneliness, sleep, anxiety, and depression. They were allocated randomly to groups either using smartphones as normal (No Change), reducing usage by 15 min per day (Reduce), or reducing use by 15 min and substituting another activity during this time (Reduce + Activity). After 3 months, they completed the same questionnaires again. There was unexpectedly low compliance with the Reduce + Activity (leisure substitution) intervention. In contrast, there was a significant reduction in screentime for the Reduce group compared to the other two groups. There was a significant improvement in the Reduce group in general health, immune function, loneliness, and depression compared to the other groups. These findings extend previous results from similar studies and suggest limiting screentime may be beneficial to health and wellbeing.

Parents, teens and screens during COVID-19 containment: An exploratory study.

One of the main concerns of parents is the amount of screen time of their teenagers, and most of them try to set rules about it. The objective of this exploratory study was to compare whether parents' rules changed during confinement and whether these changes were successful. We studied a group of parents (N= 47) of 13-year-olds in Switzerland surveyed before and during the COVID-19 pandemic. Most parents (83%) indicated that screen-time rules for their teens had changed during containment, mainly to be less strict. Although only a minority of parents were successful in defining screen-time spaces or schedules for their teenagers, almost three out of four were successful when they encouraged non-screen-based activities. This exploratory study reveals that, during containment, parents decided to be less strict with their teens' screen-time use even though it remained their main worry. However, it also suggests that when activities non-involving screens are proposed, teens are likely to participate. These results seem to indicate that reducing screen time is not a matter of imposing restrictions but, rather, of proposing alternatives. Finally, further research is warranted to assess whether these changes in screen-time use are exceptional or here to stay.

Association of Junk Food Consumption, Daily Screen Time and Daily Physical Activity with Overweight and Obesity among School Children Aged 8-10 Years- A Cross-sectional Case-control Study

Introduction: The prevalence of obesity among school children in Kerala is on a steady rise. Consumption of food with high glycaemic index, change in sleep patterns, reduced physical activity and the use of screen has been linked to obesity in children. Published literature on this association is scarce from urban Thiruvananthapuram, hence, the present study. Aim: To identify the association of various risk factors such as frequency of junk food consumption, dietary preferences, physical activity and daily screen time and weight related disorders among school going children (8-10 years) in Thiruvananthapuram. Materials and Methods: The present cross-sectional casecontrol study was conducted in one Rural Government School (Venjaramoodu Government Upper Primary School) and one Urban Private School (S.N. Public School, Chenkottukonam) of Thiruvananthapuram, Kerala, India, and enrolled school going children aged 8-10 years with higher than recommended Body Mass Index (BMI) for age as cases, age and gendermatched children with normal BMI as controls. Participants with BMI above 23rd and below 27th adult equivalent for age and gender were considered overweight and those above 27th adult equivalent for age and gender were considered as obese. A structured questionnaire was sent home with the children, and the parents were requested to answer the questions along with written informed consent. Socio-demographic parameters, anthropometric measurements were obtained by trained staff, dietary habits, and details regarding physical activity and screen usage were collected. Variables were categorised according to the standard recommendations by World Health Organisation (WHO) and Indian Association of Paediatrics (IAP). Variables were expressed as frequencies and the tests of significance used were Chi-square test and Odds ratio, to express the strength of association between parameters. A p-value &lt;0.05 was considered statistically significant. Results: The mean age of cases and controls was nine years. A total of 708 school children were screened and 352 participants (175 cases and 177 controls) were enrolled in the present study. The BMI of cases was 29.3 kg/m2 and of controls was 20.2 kg/ m2 . Higher than recommended screen time (p&lt;0.001), more frequent junk food consumption (p&lt;0.001) and lack of physical activity (p&lt;0.001) were found to be significantly associated with obesity and overweight. Dietary preference was not associated with obesity or overweight and obesity and overweight was more common in children studying in private schools (p&lt;0.001). Conclusion: Reducing screen time, reducing junk food consumption and increasing physical activity will help in reducing the prevalence of life style diseases among school children. Further evaluation is necessary to determine the factors contributing to the increased prevalence of these disorders in private schools.

REMINDEE - A Break Time Reminder Application

The usage of mobile devices has been steadily increasing, with the average time spent on mobile devices exceeding 4.5 hours per day in 2022, leading to negative impacts on users' health. In response to this issue, the REMINDEE project was developed to create a mobile app using Flutter that promotes regular breaks from screen time. The app encourages users to take short breaks, following the 20-20-20 rule, which involves looking away from the screen every 20 minutes, for 20 seconds, at an object that is 20 feet away. During break time, the app blocks all actions on the device, ensuring that the user cannot continue using the device. The project aims to reduce screen time and encourage users to take regular breaks, which can help reduce eye strain, prevent headaches, and improve overall health. The app also allows users to customize their break time, set reminders, and view their usage statistics to help monitor their progress. Ultimately, the REMINDEE project aims to promote healthy screen time habits, allowing users to maintain their health and well-being while still staying connected to their devices.

Digital Strategies for Screen Time Reduction: A Randomized Field Experiment

Many consumers nowadays wish to reduce their smartphone usage in the hope of improving productivity and well-being. We conducted a pre-registered field experiment (N = 112) over a period of several weeks to test the effectiveness of two widely available digital strategies for screen time reduction. The effectiveness of a design friction intervention (i.e., activating grayscale mode) was compared with a goal-setting intervention (i.e., self-commitment to time limits) and a control condition (i.e., self-monitoring). The design friction intervention led to an immediate, significant reduction of objectively measured screen time compared with the control condition. Conversely, the goal-setting intervention led to a smaller and more gradual screen time reduction. In contrast to the popular belief that reducing screen time has broad benefits, we found no immediate causal effect of reducing usage on subjective well-being and academic performance.

The Effect of Parent Training Programmes on Screen Time and Social Function in Children with Autism Spectrum Disorder.

Children with autism spectrum disorder (ASD) are susceptible to excessive electronic screen media (ESM) use. This study aimed to evaluate the effectiveness of a parent training programme in improving the screen time and social functioning of children with ASD. This pre-/post-test quasi-experimental study involved parents by providing them with structured education based on the American Academy of Pediatrics (AAP)' screen time recommendations. In total, 259 children with ASD aged 3 years old-12 years old were eligible. Of those children, 26 were excluded due to comorbidities or taking medications. Additionally, 28 parents participated. Children's screen time were recorded, and social behaviour was scored using the Social Responsiveness Scale pre- and post-intervention. There were significant reductions in the average daily screen time of children with ASD after their parents attended the training programme (-51.25 min; 95% CI: -78.40, -24.10). In subgroups with reduced screen time, the treatment effect of the intervention was significant in improving the social responsiveness total score (-3.09; 95% CI: -5.96, -0.22), the social communication scale (-3.64; 95% CI: -5.91, -1.36) and the restricted interest and repetitive behaviour (RRB) scale (-5.27; 95% CI: -10.29, -0.25). Parental training is effective in reducing screen time and improving social functioning in children with ASD.

Triggers and clinical changes of childhood primary headache characteristics during COVID-19 pandemic lockdown.

Children with primary headache are particularly vulnerable to the negative impacts of the pandemic due to factors like increased social isolation, disruption of sleep and impairment of healthy diet. We aimed to investigate the clinical changes and triggering factors for childhood primary headaches to demonstrate the impact of the pandemic lockdown. Children aged between 60months and 18years with headache complaint attending the general outpatient clinic between December 2019 and December 2020 were included in the study. Patients were classified according to ICHD-3 regarding clinical and laboratory data. Primary headaches diagnosed before (December 2019-March 2020) and during the pandemic lockdown (April 2020-December 2020) were divided into two groups as migraine and tension-type headache (TTH). Clinical picture and triggering factors were compared between groups to illustrate the effect of the lockdown. The study included 612 subjects, with 463 patients (76%) classified in the primary headache group and 149 (24%) in the secondary headache group. Among the first group, 267 patients (58%) had migraine and 196 patients (42%) had TTH. Comparisons between before and during the pandemic lockdown showed significant increased frequency of TTH, but no difference in the frequency and duration of migraine. Both screen exposure and sleep pattern changes were found to be significantly increased in the TTH group during the pandemic lockdown. We found a significant increase in the attack frequency for TTH patients during the pandemic lockdown. Reduction in screen time is an important strategy in preventing primary headache attacks in children.

The impact of Allied Health Professionals on the primary and secondary prevention of obesity in young children: A scoping review.

Allied Health Professionals (AHPs) have the capacity to promote healthy behaviours in young children through routine 'contact points', as well as structured weight management programmes. This scoping review aims to evaluate the impact of AHPs in the prevention of obesity in young children. Databases were searched for relevant evidence between 1st January 2000 and 17th January 2022. Eligibility criteria included primary evidence (including, but not limited to; randomized controlled trials, observational studies, service evaluations) evaluating the impact of AHPs on the primary and secondary prevention of obesity in young children (mean age under 5 years old). AHP-related interventions typically demonstrated improvements in outcomes such as nutritional behaviour (e.g. lower sweetened drink intake), with some reductions in screen time. However, changes in weight outcomes (e.g. body mass index (BMI) z-score, BMI) in response to an AHP intervention were inconsistent. There was insufficient data to determine moderating effects, however tentative evidence suggests that those with a lower socioeconomic status or living in an underprivileged area may be more likely to lose weight following an AHP intervention. There was no evidence identified evaluating how AHPs use routine 'contact points' in the prevention of obesity in young children. AHP interventions could be effective in optimizing weight and nutritional outcomes in young children. However, more research is required to determine how routine AHP contact points, across the range of professional groups may be used in the prevention of obesity in young children.

The relationships between parents’ and children’s screen times on body mass index: a cross-sectional path analysis

BackgroundUnderstanding factors contributing to an individual reducing screen time is essential for promoting a healthy weight. Parents’ behavior affects children by influencing their daily decision-making through modeling, rules or restrictions, social support, and co-participation. We examined how the direct and indirect effects of parents’ and children’s behaviors regarding screen time influenced body mass index (BMI) among Japanese elementary school children.MethodsWe included 283 Japanese children, one child per household, aged 6–12 years, who were randomly selected from resident registries of two cities. The questionnaires were completed by children and their mothers and fathers. Screen time and sociodemographic attributes, including sex, age, employment status, height, and weight, were assessed using a mail-based survey. Path analyses were conducted to determine associations among children’s, fathers’, and mothers’ variables. It was hypothesized that after controlling for household income and children’s sex and age, mothers’ and fathers’ screen time on weekdays and weekends would be related to children’s weekdays and weekend screen time, respectively. In addition, we hypothesized that children’s weekday and weekend screen time was related to children’s BMI.ResultsBoth fathers’ and mothers’ weekday screen times were associated with children’s weekday and weekend screen times. BMI was affected by children’s weekday screen time (0.117). The path coefficients for the indirect effects of mothers’ and fathers’ screen time on children’s BMI through children’s weekday screen time were 0.016 from the fathers’ weekday screen time and 0.024 from the mothers’ weekday screen time (GFI = .980, AGFI = .953, RMSEA = .030, AIC = 93.030).ConclusionsBoth fathers’ and mothers’ weekday screen times indirectly affected children’s BMI through children’s weekday screen time among Japanese elementary school children. The strongest indirect effects could be seen by examining the paths of a mother’s weekday screen time through children’s screen time to BMI. Mothers who spend much time with their children are role models, and their behavior could affect the child’s behavior. The findings imply that intervention strategies to reduce screen time in children should also focus on modeling the mothers’ behavior.

Physical activity and screen time in Swedish children and adolescents: The generation pep study 2018-2021.

To analyse physical activity and screen time trends annually between 2018 and 2021 in large population-based samples of Swedish children and adolescents. This is a repeated cross-sectional study using data collected over 4 years (2018-2021) using simple probability sampling of Swedish children and adolescents aged 4-17 years. The web-based questionnaire, including questions on physical activity and screen time, was filled out by a parent if the child was <12 years of age and by the adolescents themselves if they were ≥ 12 years. Sociodemographic data was collected from the parents. No significant difference in physical activity was observed in 2020 and 2021 compared to 2019. However, older children/adolescents and girls have higher odds to be in a lower physical activity category (p-values<0.001). With regards to screen time, there was a significant increase in reported screen time from 2018 to 2021 for children and adolescents, with screen time peaking in 2020 (p-values<0.001). This is the first study in Sweden evaluating trends in physical activity and screen time in large population-based samples spanning from pre-school to adolescence. Interventions to promote physical activity, especially in the older age groups and to reduce screen time in a Swedish context are warranted.

A Rapid Review of the Impact of Family-Based Digital Interventions for Obesity Prevention and Treatment on Obesity-Related Outcomes in Primary School-Aged Children.

Virtual delivery of obesity prevention and treatment programs may be effective for supporting children and families to adopt healthy lifestyle changes while enhancing program accessibility. This rapid review aimed to summarize the impact of family-based digital interventions for childhood obesity prevention and treatment. Four databases were searched up to February 2021 for trials of interactive digital programs aimed to prevent and/or treat obesity in children aged 5-12 years and reported diet, physical activity, sedentary behavior, sleep, or weight-related outcomes in children. A total of 23 publications (from 18 interventions) were included. Behavior change theories were used in 13 interventions with "Social Cognitive Theory" applied most frequently (n = 9). Interventions included websites (n = 11), text messaging (n = 5), video gaming (n = 2), Facebook (n = 3), and/or mobile applications (n = 2). Studies reported changes in body mass index (BMI; n = 11 studies), diet (n = 11), physical activity (n = 10), screen time (n = 6), and/or sleep (n = 1). Significant improvements were reported for diet (n = 5) or physical activity (n = 4). Two of the six interventions were effective in reducing screen time. Digital interventions have shown modest improvements in child BMI and significant effectiveness in diet and physical activity, with emerging evidence supporting the use of social media and video gaming to enhance program delivery.

Parental Intervention Strategies to Reduce Screen Time Among Preschool-aged Children: A Systematic Review

Aims: Children below five years have been the target of screen time guidelines. The adverse health outcomes associated with it require focusing on prime strategies for reducing screen time. The current study reviews parental intervention strategies to reduce screen time among preschool-aged children. Design: Systematic review. Data sources: A total of five databases of the Cochrane register of controlled trials, CINAHL, Medline PubMed, and Scopus databases were searched from May 1 to 31, 2020. Review Methods: The keywords of “screen time”, “television”, “video”, “computer”, “mobile device”, “hand phone”, “media use”, “preschool-aged children”, “interventions”, and “strategies” used for search. The inclusion criteria are limited to specific study populations, intervention, comparison and outcomes (PICOs), language, and published study types. The quality of articles was assessed using the Cochrane Risk of Bias (RoB) tool. Results: A total of six studies that met the inclusion criteria were further analysed. It showed that besides providing knowledge and awareness regarding screen time, restrictive practices, offering alternative activities to parents and removing the screen from the child’s bedroom were the most common strategies used by successful studies. The duration of intervention between 6-8weeks was sufficient to observe screen time reduction, while face-to-face methods dominated the mode of delivery. Increasing parental self-efficacy, listing outcome expectations, and reinforcement strategies targeting both the parents and their home environment were beneficial in reducing screen time. Conclusion: Future screen time reduction studies could benefit from incorporating the above approaches for screen time reduction intervention among preschool children.
