Exposure to Electronic Media: Children Diagnosed With Speech Delay

Today’s daily life is overwhelmed with electronic media and excessive technology exposure among young children became an expert users. Early exposure to technology such as television, smart phone, tablet and computer affected the language development among children. The American Academy of Pediatrics recommended that children under two years old should have minimal screen media exposure. Aim: To investigate the exposure to electronic media among children diagnosed with speech delay. Methods: Retrospective descriptive design was done on a convenient sample of 100 children with their parents who were attended psychiatric clinic in the Center of Social and Preventive Medicine, Cairo University who diagnosed with speech delay. Structured interview questionnaire developed by the researchers, includes four parts: personal characteristics of children and their parents; family electronic devices usage at home; types of electronic media exposure from 0-6 years old and child history of the duration of electronic media exposure from 0-6 years old. Result: An average duration of electronic media per day exposure was 3.74 hours for children less than 2 years old, 3.81 hours for children from 2 to less than 4 years and 3.41 hours for children from 4 to 6 years who suffered from speech delay, slightly less than two third of children less than 2 years old watched television, slightly more than one quarter of them (28%) used smart phone and increased to 42% of children from 2 to 4 years old, only 3 to 12 % of young children from 0-6 years old viewed tablet and one fifth of young children (2-6 years) viewed computer. Conclusion: Average duration of electronic media exposure per day for children less than 2 years who suffered from speech delay was 3.74 hours, slightly less than two third of them watched television and slightly more than one quarter of them used smart phone. Recommendation: Further longitudinal study of early electronic media viewing and language development that follows children from birth to beyond age five.

Media Exposure in Low-Income Preschool-Aged Children Is Associated with Multiple Measures of Self-Regulatory Behavior.

Excessive screen media exposure in childhood is associated with parent-reported self-regulation difficulties. No studies have used laboratory-based or teacher-reported measures of child self-regulatory behaviors. This study examines cross-sectional associations between preschooler screen media exposure and multiple measures of self-regulatory behaviors. Preintervention data were used from 541 preschoolers in the Growing Healthy study, an obesity prevention trial (2011-2015). Screen media exposure was measured by daily screen media exposure (hr/d), television (TV) in the bedroom, frequency of background TV, and TV with meals (1 = rarely/never, 4 = frequently). Child self-regulatory behaviors were measured by the following: child ability to delay gratification, a standardized waiting paradigm; teacher-reported Social Competence and Behavior Evaluation; and parent-reported difficult temperament on the Child Behavior Questionnaire (CBQ). Multivariate regression analyses modeled screen media exposure predicting each self-regulatory measure, adjusting for child age, sex, parent age, education, marital status, income-to-needs ratio, number of adults in household, parent depressive symptoms, and sensitivity. Children were aged 4.1 years (SD = 0.5), parents were aged 29.6 years (SD = 6.8), 48% had high school education or less, and 67% were married. Daily screen media exposure and background TV were associated with weaker observed self-regulation (β: -10.30 seconds for each hr/d media, -12.63 seconds for 1-point increase, respectively). Background TV and TV with meals were associated with greater parent-reported difficult temperament (β: 0.04 and 0.05 CBQ, respectively, for 1-point increase). Greater screen media exposure had small but significant associations with weaker observed and parent-reported, but not teacher-reported, self-regulatory behaviors. Longitudinal studies are needed to determine the directionality of associations.

Screen Media Exposure and Obesity in Children and Adolescents.

Obesity is one of the best-documented outcomes of screen media exposure. Many observational studies find relationships between screen media exposure and increased risks of obesity. Randomized controlled trials of reducing screen time in community settings have reduced weight gain in children, demonstrating a cause and effect relationship. Current evidence suggests that screen media exposure leads to obesity in children and adolescents through increased eating while viewing; exposure to high-calorie, low-nutrient food and beverage marketing that influences children's preferences, purchase requests, consumption habits; and reduced sleep duration. Some evidence also suggests promise for using interactive media to improve eating and physical activity behaviors to prevent or reduce obesity. Future interdisciplinary research is needed to examine the effects of newer mobile and other digital media exposures on obesity; to examine the effectiveness of additional interventions to mitigate the adverse effects of media exposures on obesity and possible moderators and mediators of intervention effects; to effectively use digital media interventions to prevent and reduce obesity; and to uncover the mechanisms underlying the causal relationships and interactions between obesity-related outcomes and media content, characteristics, and context.

Investigating the association between children’s screen media exposure and vocabulary size in the UK

Children are growing up in a digital age with increasing exposure to television and touchscreen devices. We tested whether exposure to screen media is associated with children’s early language development. One hundred and thirty-one highly educated caregivers of UK children aged 6–36 months completed a media exposure questionnaire and vocabulary measure. 99% of children were read to daily, 82% watched television, and 49% used mobile touchscreen devices daily. Regression analyses revealed that time spent reading positively predicted vocabulary comprehension and production scores at 6–18 months, but time spent engaging with television or mobile touchscreen devices was not associated with vocabulary scores. Critically, correlations revealed that time spent reading or engaging with other non-screen activities was not offset by time spent engaging with television or mobile touchscreen devices. Thus, there was no evidence to suggest that screen media exposure adversely influenced vocabulary size in our sample of highly educated families with moderate media use.

Evening media exposure reduces night-time sleep.

To investigate whether evening media exposure, bedroom media use and night-time sleep duration at age 6 months are associated with night-time sleep duration in 12-month-old Thai infants. We enrolled 208 infants in this study at 6 months of age. They were followed-up at 12 months of age. A sleep diary was used to document the infant's sleep onset and wake time at each visit. Night-time sleep duration was then calculated at both ages. Screen media exposure in the household was assessed in depth at both visits. Infants who were exposed to screen media in the evening at 12 months of age had a 28-min decrease in 12-month night-time sleep duration on weekdays. Moreover, infants who were exposed to screen media in the evening at age 6 months and 12 months had shorter 12-month night-time sleep duration compared with those who were not exposed to screen media after 7 pm at both ages. Night-time sleep duration at 12 months of age was also directly related to 6-month night-time sleep duration. Infants exposed to screen media in the evening at 12 months of age had decreased 12-month night-time sleep duration. To promote good sleep hygiene and optimal sleep for infants at this age, screen media exposure after 7 pm should be avoided.

Association of Screen Time Use and Language Development in Hispanic Toddlers

This study examined the association between screen media use, media content, and language development among 119 Hispanic infants and toddlers. Children and their caregivers were recruited through an urban, Early Head Start program. Duration and content of screen media exposure was measured through a 24-hour recall questionnaire, and language development was measured at baseline and at 1-year follow up. Children in the sample spent an average of 3.29 hours engaged with screen media (median 2.5 hours per day). In both cross-sectional and longitudinal analyses, children who watched over 2 hours of television per day had increased odds of low communication scores. Whereas child-directed media was associated with low language scores, adult-directed media was not. Our findings support the mounting literature on the deleterious impacts of screen media in toddler's language development. Guidance and alternatives to screen media use should be available to families in pediatric practices and early childhood centers.

US Preschoolers' Media Exposure and Dietary Habits: The primacy of television and the limits of parental mediation

A potential barrier to healthy eating in childhood is media marketing of obesogenic foods, yet little research has linked young children's media and dietary habits. This study reports data from 423 parents and 354 2- to 4-year-old children in the Midwestern United States, from the first wave of a 3-wave prospective panel study. Variables included family demographics, child media exposure, parent mediation of TV, child dietary habits, and child BMI. Controlling demographics and parent BMI, media exposure and parental mediation were unrelated to child BMI. However, TV viewing predicted increased intake of high-energy, low-nutrient (HELN) foods and decreased intake of fruits and vegetables. Restrictive parental mediation reduced some of these relationships, whereas coviewing and instructive mediation increased others. TV viewing continued to predict intake of some HELN foods for the 322 children whose parents limited their daily screen media exposure to 2 hours. Discussion focuses on future research directions and policy implications.

Parents of Preschoolers: Expert Media Recommendations and Ratings Knowledge, Media-Effects Beliefs, and Monitoring Practices

Given the increase in screen media targeted at the very young, the purpose of this study was to examine preschooler parents' knowledge about expert recommendations for young children's screen media experience, their knowledge of specific screen media ratings, their beliefs about screen media effects, and actual monitoring practices. Parents of 94 children <5 years of age (mean age: 2.95 years) were surveyed. Questionnaires were distributed in day care centers and completed at the parents' convenience. The questionnaire included background questions about parental education, age and gender of child, and parents' perceptions of their child's favorite television show and favorite video or computer game. Eleven multiple-choice questions assessed the respondent's knowledge of expert recommendations for screen media for preschoolers and the meaning of television and video game content ratings. Fourteen questions addressed the typical amount of their preschooler's screen media exposure, parental rules regarding screen media use, and parents' beliefs about appropriate use of screen media for preschoolers. Preschoolers were exposed to an average of approximately 12 hours of screen media in a typical week. Parents believe that media do have either short- or long-term effects on preschoolers. Performance on factual questions was poor (mean score: 2.83 of 11). In particular, only 34% of the parents correctly identified the expert recommendation for children >2 years of age. Parents should continue to be educated about the need for preschoolers to participate in activities that promote language development, socialization, imagination, and physical activity. Although professionals should work to improve the ratings, and ultimately to implement a universal ratings system for all screen media, parents need to be encouraged to improve their understanding of current recommendations for screen media exposure and television and video game ratings.

Does Children's Screen Time Predict Requests for Advertised Products?

To examine children's screen media exposure and requests for advertised toys and food/drinks. Prospective cohort study. Twelve elementary schools in northern California. Eight hundred twenty-seven third grade children participated at baseline; 386 students in 6 schools were followed up for 20 months. None. Child self-reported requests for advertised toys and foods/drinks. At baseline, children's screen media time was significantly associated with concurrent requests for advertised toys (Spearman r = 0.15 [TV viewing] and r = 0.20 [total screen time]; both P<.001) and foods/drinks (Spearman r = 0.16 [TV viewing] and r = 0.18 [total screen time]; both P<.001). In prospective analysis, children's screen media time at baseline was significantly associated with their mean number of toy requests 7 to 20 months later (Spearman r = 0.21 [TV viewing] and r = 0.24 [total screen time]; both P<.001) and foods/drinks requests (Spearman r = 0.14 [TV viewing] and r = 0.16 [total screen time]; both P<.01). After adjusting for baseline requests and sociodemographic variables, the relationship between screen media exposure and future requests for advertised foods/drinks remained significant for total TV viewing and total screen media exposure. The relationship with future requests for toys remained significant for total screen media exposure. Screen media exposure is a prospective risk factor for children's requests for advertised products. Future experimental studies on children's health- and consumer-related outcomes are warranted.

Effects of the SMART Classroom Curriculum to Reduce Child and Family Screen Time

Evidence for adverse effects of screen media exposure has led to recommendations to limit children's screen time. This paper describes a randomized controlled trial of SMART (Student Media Awareness to Reduce Television), an 18-lesson, theory-based classroom curriculum to reduce screen time among third and fourth grade children in two matched public elementary schools (n = 181). Intervention school children significantly reduced their weekday television viewing and weekday and Saturday video game playing compared to controls. Greater effects were found among boys and more adult-supervised children. Mothers, fathers, and siblings and other children in intervention school households also reduced their television viewing. The findings demonstrate the efficacy of a classroom intervention to reduce screen time among elementary school children and their family/household members.
