Infant screen media usage and social-emotional functioning

Intergenerational care and rural childhood obesity in the digital era: Based on screen exposure perspective

Background

Rural Chinese children are experiencing increasing obesity rates, yet studies often neglect the impact of IT and screen media growth on obesity risks in the context of intergenerational care, leading to incomplete strategies for the digital era.

Methods

By comprehensively utilizing the data on rural children aged 6-17 from the China Family Panel Studies (CFPS) and the China Health and Nutrition Survey (CHNS), this study aims to test the logical chain and specific mechanisms regarding "intergenerational care - screen exposure - rural childhood obesity". We employ the Propensity Score Matching (PSM) and Generalized Propensity Score Matching (GPSM) methods to respectively address the self-selection biases associated with inter-generational care and children's screen exposure behaviors.

Results

1) Intergenerational care significantly increases screen exposure among rural children. 2) Gender bias increases the risk of screen exposure for rural boys under intergenerational care. 3) Children with higher screen exposure levels are more affected by intergenerational care, which further undermines parental supervision. 4) Children's screen exposure leads to increased sedentary time and higher probability of purchasing unhealthy foods, thereby exacerbating obesity. This process is facilitated by enhancing preferences for snacks, fast food, and beverages, and weakening preferences for physical activity. 5) GPSM analysis indicates that children's screen exposure has an inverted "U"-shaped impact on unhealthy dietary preferences and a "U"-shaped impact on activity preferences. It results in a nonlinear positive impact of screen exposure on obesity. This study reveals a positive association between screen exposure and obesity, offering new insights into how intergenerational care in the digital era may elevate obesity prevalence through excessive screen time for rural children.

The relationship between video games and social-emotional delay in Chinese rural preschoolers: A comparison of five types of media video games and social-emotional delay

BACKGROUND

Recent studies have revealed a negative relationship between children's digital media use and social-emotional development. However, few studies distinguish between different digital devices and the different functions they provide that may lead to different outcomes.

METHODS

This study explored the relationship between young children's time spent on various digital devices and their social-emotional delay based on a survey of 1182 preschoolers (3 to 6 years old) in rural China. Children's social-emotional delay was assessed through a validated screening tool (ASQ-SE II).

RESULTS

Children's time spent on television, computers, tablets, or smartphones was not associated with their social-emotional delay. However, their risk of social-emotional delay increased as their time spent on game consoles increased. This relationship was reflected in five of the seven behavioural areas of children's social-emotional development (i.e., self-regulation, compliance, affect, social communications, and interactions with people). Moreover, it did not vary between children with different socioeconomic statuses.

CONCLUSIONS

This study suggests a possible relationship between children's social-emotional delay and video games, which might need to be paid more attention to than other media types.

Touchscreens can promote infant object-interlocutor reference switching

We re-examine whether the type of object played with influences parent-infant joint attention. A within-participants comparison of 24 parent-9-month-old dyads, used head-mounted eye-tracking to measure parental naming and infant attention during play with touchscreen apps on a touchscreen tablet or matched interactive toys. Infants engaged in sustained attention more to the toy than the tablet. Parents named objects less in toy play. Infants exhibited more gaze shifts between the object and their parent during tablet play. Contrasting previous studies, these findings suggest that joint tablet play can be more interactive than with toys, and raise questions about the recommendation that infants should not be exposed at all to such technology.

Infant screen media and child development: A prospective community study

The current study examined longitudinal associations between early screen media exposure (assessed at 6, 12, and 24 months) and the child's motor and language/communication development at the ages of 24 and 36 months. We also aimed to study whether these associations varied by socioeconomic status (SES). Participants were 179 parent-infant dyads, recruited from well-baby clinic services during routine visits. Child development measures included standardized measures of developmental milestones as assessed by professionals and referral data to child developmental centers. Both measures were retrieved from the official health maintenance organization records by an expert in child development. Results indicated that screen exposure at 6 and 12 months was associated with a higher risk for language/communication deficits at 36 months in children with moderate or high SES but not in children with low SES. Our findings are consistent with existing literature demonstrating cross-sectional and longitudinal associations between early screen exposure and language development deficits. Given that media use practices and motivations vary among families from different backgrounds, further investigation of the interaction between SES and screen exposure is needed.

Outdoor Play as a Mitigating Factor in the Association Between Screen Time for Young Children and Neurodevelopmental Outcomes

Importance

Whether the association between higher screen time in infancy and later suboptimal neurodevelopment can be mitigated by frequency of outdoor play is unknown.

Objective

To investigate whether higher screen time at age 2 years is associated with neurodevelopmental outcomes at age 4 years and whether this association is mediated by frequency of outdoor play at age 2 years 8 months.

Design, Setting, and Participants

Participants were a subsample of the Hamamatsu Birth Cohort Study for Mothers and Children (HBC Study, N = 1258). Children were born between December 2007 and March 2012 and followed up from 1 year 6 months to 4 years. The analysis was conducted from April 2021 to June 2022.

Exposures

Screen time longer than 1 hour a day at age 2 years was coded as higher screen time.

Main Outcomes and Measures

Standardized scores for communication, daily living skills, and socialization domains of the Vineland Adaptive Behavior Scale, second edition, at age 4 years were used (mean [SD], 100 [15]). The mediating factor was frequency of outdoor play at age 2 years 8 months, with 6 or 7 days per week coded as frequent outdoor play.

Results

Of 885 participants, 445 children (50%) were female; mean (SD) screen time per day was 2.6 (2.0) hours. Causal mediation analyses revealed that higher screen time at age 2 years was associated with lower scores in communication at age 4 years (nonstandardized coefficient b = -2.32; 95% CI, -4.03 to -0.60), but the association was not mediated by frequency of outdoor play. Higher screen time was also associated with lower scores in daily living skills (b = -1.76; 95% CI, -3.21 to -0.31); 18% of this association was mediated by frequency of outdoor play. Frequency of outdoor play was associated with socialization (b = 2.73; 95% CI, 1.06 to 4.39), whereas higher screen time was not (b = -1.34; 95% CI, -3.05 to 0.36).

Conclusions and Relevance

Higher screen time at age 2 years was directly associated with poorer communication at age 4 years. It was also associated with daily living skills, but frequency of outdoor play at age 2 years 8 months alleviated it, suggesting outdoor play mitigated the association between higher screen time and suboptimal neurodevelopment. Future research should specify the nature of the associations and intervention measures, enabling targeted interventions that reduce the potential risk in screen time.

Problematic screen media use in children and adolescents attending child and adolescent psychiatric services in a tertiary care center in North India

OBJECTIVE

The present clinic-based study aimed to evaluate screen media use among children and adolescents who had a mental disorder.

METHODS

Two hundred twelve parents of children and adolescents attending the child and adolescent psychiatric services were approached. They were asked to rate the screen media use of their child brought for psychiatric consultation using the Problematic Media Use Measure-Short Form (PMUM-SF). The DSM-5 criteria of internet gaming disorder (IGD) were applied using the PMUM-SF, which contained nine items equivalent to nine items of IGD.

RESULTS

The mean age of the patients was 13.16 years (SD: 4.06; range: 0.8-18). Only 28.3% (n = 60) were aged less than 12 years. The most common primary diagnosis was neurodevelopment disorder (n = 82; 38.7%), followed by neurotic disorder (n = 62; 29.2%) and mood disorder (n = 30; 14.2%). The most common screen media used was television (n = 121; 57.1%) followed by the mobile phone (n = 81; 38.2%). The average screen time was 3.14 hours, with a range of 0.5-7 hours, and more than two-third of children and adolescents used screen gadgets for more than the recommended duration. Slightly more than one-fourth (22.2%) of children and adolescents with mental disorders fulfilled the DSM-5 criteria of IGD. When those with and without screen media addiction were compared, those with screen media addiction were more often male, from joint or extended families, more often diagnosed with neurodevelopmental disorders and disruptive disorder, and were less often diagnosed with neurotic disorders.

CONCLUSION

About one-fourth of the children and adolescents with mental disorders had screen media addiction, and two-thirds of them used screen media for more than the recommended duration.

Toward a dimensional model of risk and protective factors influencing children's early cognitive, social, and emotional development during the COVID-19 pandemic

Variation in infants' home environment is implicated in their cognitive and psycho-social development. The pandemic has intensified variations in home environments through exacerbating socioeconomic inequalities, and increasing psychological stressors for some families. This study investigates the effects of parental (predominantly maternal) mental health, enriching activities and screen use on 280 24- to 52-month-olds' executive functions, internalising and externalising problems, and pro-social behaviour; with socioeconomic status and social support as contextual factors. Our results indicate that aspects of the home environment are differentially associated with children's cognitive and psycho-social development. Parents who experienced sustained mental distress during the pandemic tended to report higher child externalising and internalising problems, and executive function difficulties at follow-up. Children who spent more time engaged in enriching activities with their parents showed stronger executive functions and social competence six months later. Screen use levels during the first year of the pandemic were not associated with outcomes. To mitigate the risk of persistent negative effects for this 'pandemic generation' of infants, our study highlights the importance of supporting parents' mental health. As our results demonstrate the impact of social support on mental health, investing in support services and interventions promoting building support networks are likely to be beneficial.

Parental Mentalizing during Middle Childhood: How Is the Adoption of a Reflective Stance Associated with Child's Psychological Outcomes?

This exploratory cross-sectional study attempts to understand the mechanisms underlying the role of parental mentalizing in a child's psychological functioning during middle childhood by using Parental Reflective Functioning (PRF) and Parental Insightfulness (PI) constructs. The main aims are to examine the role of PI and PRF as processes capable of influencing a child's psychological functioning in terms of emotional-behavioral difficulties and social-emotional competencies. Eighty-six community parents (48 mothers, 38 fathers) and their 50 children in middle childhood (Mage = 10.10, SD = 1.13) participated in this study, recruited through a non-probabilistic sampling. The following measures were used to assess the aims of this study: Insightfulness Assessment, Parental Reflective Functioning Questionnaire, Child Behavior Checklist (CBCL) and Devereux Student Strengths Assessment (DESSA) questionnaires. Results showed that parental mentalizing was found to be significantly associated with both child's internalizing and externalizing symptoms and social-emotional competencies as reported by parents through the CBCL and DESSA questionnaires. This study may offer a contribution to the study of parental mentalizing during middle childhood, supporting the hypothesis that both parents' ability to understand their child's mental states could affect the child's psychological functioning. Clinical and theoretical implications are geared toward a family-based view with a specific focus on the importance of fostering in both parents a positive attitude toward mentalizing processes.

Association of Screen Time With Internalizing and Externalizing Behavior Problems in Children 12 Years or Younger: A Systematic Review and Meta-analysis

Importance

Currently, there is a lack of consensus in the literature on the association between screen time (eg, television, video games) and children's behavior problems.

Objective

To assess the association between the duration of screen time and externalizing and internalizing behavior problems among children 12 years or younger.

Data Sources

For this systematic review and meta-analysis, MEDLINE, Embase, and PsycINFO databases were searched for articles published from January 1960 to May 2021. Reference lists were manually searched for additional studies.

Study Selection

Included studies measured screen time (ie, duration) and externalizing or internalizing behavior problems in children 12 years or younger, were observational or experimental (with baseline data), were available in English, and had data that could be transformed into an effect size. Studies conducted during the COVID-19 pandemic were excluded. Of 25 196 nonduplicate articles identified and screened for inclusion, 595 met the selection criteria.

Data Extraction and Synthesis

The study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Extracted variables were child age, sex, and socioeconomic status; informants and measurement type for screen time and behavior problems; study publication year; and study design and quality. Data were extracted by 2 independent coders and were pooled using a random-effects model.

Main Outcomes and Measures

The primary outcome was the association of screen time duration with externalizing (eg, aggression, attention deficit/hyperactivity disorder symptoms) and internalizing (eg, depression, anxiety) behaviors or diagnoses.

Results

Of the 595 full-text articles assessed for eligibility, 87 studies met all inclusion criteria, comprising 98 independent samples and 159 425 participants (mean [SD] age, 6.07 [2.89] years; 83 246 [51.30%] male). Increased duration of screen time had a small but significant correlation with more externalizing problems (90 samples; r, 0.11; 95% CI, 0.10-0.12) and internalizing problems (43 samples; r, 0.07; 95% CI, 0.05-0.08) in children. Several methodological moderators explained between-study heterogeneity. There was evidence of significant between study heterogeneity (I2 = 87.80).

Conclusions and Relevance

This systematic review and meta-analysis found small but significant correlations between screen time and children's behavior problems. Methodological differences across studies likely contributed to the mixed findings in the literature.

"Does your baby watch TV?": The associations between at-home TV watching and laboratory challenge cortisol are different for young infants and their mothers

This longitudinal study examined associations between at-home TV watching and the biological stress response (cortisol) during a laboratory infant cognitive challenge task in 240 3- and 5-month infants and their mothers. Cortisol levels were lower in mothers of 5-month-old infants whose infants were exposed to TV at home, compared to mothers of infants that were not TV-exposed. Cortisol patterns were different across three laboratory sampling intervals for 3-month-old infants as a function of TV watching, revealing a sharp increase in laboratory cortisol only for infants who were exposed to TV at home. In contrast, there was no effect of TV exposure in 5-month-old infants' cortisol. Infant temperament and demographic measures were included as control variables in regression models to predict maternal and infant cortisol. At 3 months, for the T3 cortisol sampling interval, and at 5 months across all three sampling intervals, maternal cortisol levels were significantly predicted by infant TV exposure after accounting for variance due to these control variables. Our findings show the strong influence of the infant TV-exposure factor in the biological stress response of mothers of young infants, and suggest that infant TV exposure may influence self-regulation in 3-month-old infants.
