The Impact

AbstractThe impact of COVID-19 on social life has been drastic and global. However, the different numbers of cases and different actions in different countries have been leading to various interesting yet unexplored effects on human behavior. In the present study, we compare the physical activity and recreational screen time of a representative sample of 1711 4- to 17-year-olds before and during the strictest time of the first COVID-19 lockdown in Germany. We found that sports activity declined whereas recreational screen time increased. However, a substantial increase in habitual physical activities leads to an overall increase in physical activity among children and adolescents in Germany. The effects differ in size but not in their direction between age groups and are stable for boys and girls. We conclude from this natural experiment that physical activity among children and adolescents is highly context-driven and mutual and does not act as a functional opposite to recreational screen time.

AbstractBackgroundThere are limited studies about the association of physical activity (PA) and screen time (ST) with psychiatric distress (PD) among children and adolescents including Iranian populations.ObjectiveWe aimed to examine the independent and combined associations of PA and ST with PD among children and adolescents.MethodThis school-based nationwide survey was carried out among 14 880 students (50.8% boys and 75.6% urban inhabitants), of age 6–18 years by cluster and the stratified multistage sampling method from 30 provinces of Iran. The students and their parents completed two sets of questionnaires obtained from Global School Health Survey with several questions about the PD. The time spent on watching TV/video and computer games and PA were assessed by self-administered validated questionnaires.ResultsThe study had a participation rate of 90.6%. Of the studied students, 45.85%, 83.62%, 37.81% and 23.92% had depression, anger, insomnia and worthlessness, respectively. The prevalence of confusion, anxiety and worry was reported in 19.6%, 55.17% and 75.31% of the students, respectively. The combined effect of PA and that of ST showed that students with high PA and low ST had the lowest prevalence of PD, while the highest prevalence of these PD was observed among students with low PA combined with high ST (p < 0.05 for all).ConclusionsIncreasing PA and reducing ST should both be considered for improving the mental health status of children and adolescents.

Abstract Background There is increasing concern about the time people spend in sedentary behaviour, including screen time, leisure and occupational sitting. The number of both primary research studies (published trials) and reviews has been growing rapidly in this research area. A summary of the highest level of evidence that provides a broader quantitative synthesis of diverse types of interventions is needed. This research is to articulate the evidence of efficacy of sedentary behaviour interventions to inform interventions to reduce sitting time. The umbrella review, therefore, synthesised systematic reviews that conducted meta-analyses of interventions aiming at reducing sedentary behaviour outcomes across all age group and settings. Method A systematic search was conducted on six databases (MEDLINE Complete, PsycINFO, CINAHL, Global Health via EBSCOhost platform, EMBASE, and Cochrane Central Register of Systematic Reviews). Included articles were systematic reviews with meta-analysis of interventions aiming at reducing sedentary behaviour (screen time, sitting time or sedentary time) in the general population across all age group. Results Seventeen reviews met the inclusion criteria (7 in children and adolescent, 10 in adults). All reviews of sedentary behaviour interventions in children and adolescents investigated intervention effectiveness in reducing screen time. Six out of 11 meta-analyses (reported in 7 reviews) showed small but significant changes in viewing time. All reviews of sedentary behaviour interventions in office workplaces indicated substantial reduction in occupational sitting time (range: 39.6 to 100 min per 8-h workday). Sub-group analyses reported a trend favouring environmental change components such as sit-stand desks, active permissive workstations etc. Meta-analyses indicated that sedentary behaviour interventions were superior to physical activity alone interventions or combined physical activity and sedentary behaviour interventions in reducing sitting time. Conclusion The current systematic reviews and meta-analyses supported sedentary behaviour interventions for reducing occupational sitting time in particular, with small changes seen in screen time in children and adolescents. Future research should explore approaches to maintaining behaviour change beyond the intervention period and investigate the potential of sedentary behaviour reduction interventions in older age groups in non-occupational settings.

AbstractBackground:This study aims to assess the joint association of screen time (ST) and physical activity (PA) with anthropometric indices among Iranian children and adolescents.Methods:In this national study, 23,183 school students, aged 6–18 years, were studied. By using a multi-stage cluster sampling method, they were selected from rural and urban areas of 30 provinces of Iran. ST and PA were assessed by self-administered validated questionnaires. Height, weight, hip and waist circumferences (WC) were measured according to standard protocols, and body mass index (BMI) was calculated. ST of <2 h per day was categorized as “low” and ≥2 h per day as “high”. PA levels were obtained by a 7-day recall of sports or activities that made participants sweat or make their legs feel tired, or games that made them breathe heavily. Using this questionnaire, the score of 1–1.9 was categorized as “low” and scores between 2 and 5 as “high” PA. Logistic regression analyses were used to evaluate the joint association of PA and ST categories with odds of anthropometric measures.Results:In both genders, those students categorized as “Low PA & High ST” had the highest levels of BMI z-scores (boys: 0.15±1.12, girls: 0.17±1.08), WC (boys: 69.93±13.89 cm, girls: 67.30±11.26 cm), and hip circumference (boys: 82.41±13.90 cm, girls: 84.05±13.7 cm), as well as the highest prevalence of overweight (boys: 15.32%, girls: 14.04%) (p<0.001 in all comparisons). In linear multivariate model, students with “High PA & High ST” had significant increased levels of z-scores for BMI, WC and hip circumference (p<0.05).Conclusions:The current findings underscore the importance of reducing ST along with increasing PA for prevention and control of excess weight in children and adolescents.

Objective: To identify risk and protective factors for mental health symptoms associated with lifestyle changes caused by home confinement in pediatric subjects and in children and adolescents with a neuropsychiatric disorder.Study design: This was a prospective, cross-sectional study conducted from May 10 to May 31, 2020. Two online anonymous surveys were developed: population-based and clinical-based (children with neuropsychiatric disorders). Outcomes included emotional and behavioral symptoms, as assessed by psychometric scales (BPSC, PPSC, PSC, CES-DC and SCARED, respectively), and lifestyle changes during home confinement (i.e., physical activity, screen time, home schooling, reading).Results: The sample included 9,688 pediatric subjects, and 289 children and adolescents with a neuropsychiatric disorder. The presence of siblings was a protective factor in all ages. In pre- and school children: male sex, a diagnosis of autism, residency in highly affected areas, high parental educational level or job loss, and screen time (&gt;2 h/day) were risk factors. Physical activity, home-schooling, reading, talking with other people were protective factors. Residency in highly affected areas, a diagnosis of mood disorder, parental job loss, and screen time, were associated with a worsening of the depressive symptoms, whereas physical activity, talking with other people, playing with parents were protective activities. Screen time was also a risk factor for anxiety symptoms, while physical activity, reading and talking with other people were protective factors.Conclusions: This study identified risk and protective factors for mental health symptoms associated with lifestyle changes caused by COVID-19 home confinement to promote mental well-being in pediatrics during pandemic times.

The purpose of this study was to compare the degree to which children and adolescents with and without visual impairments (VIs) met national physical activity, screen-time, and sleep guidelines. This observational, cross-sectional analysis of the 2016 National Survey of Children’s Health focused on children (age 6–12 yr) and adolescents (age 13–17 yr) with and without VIs. The sample included 241 (weighted n = 472,127) and 17,610 (weighted n = 28,249,833) children, and 255 (weighted n = 505,401) and 17,417 (weighted n = 20,071,557) adolescents with and without VIs, respectively. Chi-square statistics were computed to examine the degree to which participants with and without VIs met health-behavior guidelines. Children (p = .02) with VIs were less likely to meet screen-time guidelines, but adolescents with VIs were not (p = .87). VI status was not associated with the likelihood of meeting physical activity or sleep guidelines (p < .05). Low numbers of children and adolescents with and without VIs meeting health-behavior guidelines warrant targeted interventions aimed at enhancing engagement.

Abstract Background Existing studies on health-related quality of life (HRQoL) mainly covered single growth stages of childhood or adolescence and did not report on the trends in the relationships of HRQoL with sleep duration, physical activity, and screen time. This study aimed to establish the population norm of HRQoL in children and adolescents aged 6–17 years and examine the associations of screen time, sleep duration, and physical activity with HRQoL in this population. Methods We conducted a large-scale cross-sectional population-based survey study of Hong Kong children and adolescents aged 6 to 17 years. A representative sample of students were interviewed to assess their HRQoL using PedsQL and EQ-5D-Y-5L. Multivariable homoscedastic Tobit regression with linear form or restricted cubic spline of predictors was used to analyze the associations between screen time, sleep duration, and HRQoL. Multiple imputation by chained equations was performed to deal with missing data. Results A total of 7555 respondents (mean age 11.5, SD 3.2; 55.1% female) were sampled. Their EQ VAS scores, PedsQL physical summary scores, and psychosocial summary scores were positively correlated with sleep duration and moderate/vigorous activity but was negatively correlated with screen time. Conclusions Children and adolescents who had longer exposure to screen, shorter sleep duration, and lower physical activity levels appeared to have poorer HRQoL as assessed by PedsQL and EQ-5D-Y-5L. Advice and guidance on screen time allocation for children and adolescents should be provided at the levels of school, community, and family.
