The Effect of Physical Activity Intervention on Motor Proficiency in Children and Adolescents with ADHD: A Systematic Review and Meta-analysis

Attention deficit hyperactivity disorder (ADHD) is a frequently diagnosed neurodevelopmental disorder in children and adolescents. The objective of this review was to synthesize empirical studies that investigated the effects of physical activity (PA) on motor proficiency in this population. A systematic review and meta-analysis were conducted following the cochrane guidelines for systematic reviews. In May 2022, a systematic search of eight electronic databases retrieved 476 results, which were screened independently by two reviewers. Based on the inclusion and exclusion criteria, 12 studies were selected for systematic review, and 10 were included in the meta-analysis. A beneficial effect of PA on overall motor proficiency (SMD = 1.12; 95% CI [0.63 to 1.61]; p < 0.05) was observed. Similar positive effects were found for motor proficiency composites, including object control, fine manual control, and body coordination. These results indicate that PA improves the motor proficiency of children and adolescents with ADHD.

Parental Support, Children's Physical Activity, Dietary Behaviors and Health-Related Quality of Life: Evidence From Three Asian Cities

BACKGROUND

Parental support is crucial for children's healthy lifestyle formation. The present study examined the relations between parental support (i.e., encouragement and praise), children's perceived autonomy support and behaviors in the domains of physical activity (PA) and diet, and health-related quality of life (HRQoL) simultaneously in Asia.

METHOD

Children aged 9 to 12 years and their parents (2065 dyads) in three Asian cities completed the respective questionnaires. Children reported perceived PA and dietary autonomy support, PA frequency, dietary behaviors, and HRQoL. Parents reported their PA and dietary support. The relations between parental support, children's perceived autonomy support an behaviors in the PA, and dietary domains as well as HRQoL were examined using multigroup path analyses.

RESULTS

Among three cities, the indirect effects of parental support on children's self-report PA or HRQoL via children's perceived PA autonomy support were significant. A hypothetical sequential indirect effect from parental PA support to children's HRQoL via children's perceived PA autonomy support and self-report PA was observed in Hong Kong. In Hong Kong and Taipei samples, the indirect effect of parental PA support on children's HRQoL via children's self-report PA and the indirect effect of children's perceived PA autonomy support on HRQoL via children's self-report PA were significant. In Hong Kong and Shanghai samples, children's perceived dietary autonomy support showed positive effect on HRQoL via healthy food consumption.

CONCLUSIONS

Congruent findings across three cities suggest that parents should provide support via encouragement and praise to facilitate children's perceived autonomy support and further increase PA and HRQoL. Our study adds to the literature by examining relations of parental support and children's healthy lifestyle in Asia and provides insights to parents and researchers.

Early-life activities mediate the association between family socioeconomic status in early childhood and physical fitness in early adolescence

The graded association between family socioeconomic status (SES) and physical fitness is evident, but little is known about the mechanism underlying this association. This study investigated the role of early-life activities as mediators of the longitudinal relationship between early-life SES and health-related physical fitness in 168 adolescents (51.2% boys; final mean age: 12.4 years old). In Wave 1 (2011–12), their parents completed questionnaires about family socioeconomic status (SES), parent–child activities, and child screen time. In Wave 2 (2014–15), participants’ physical activity levels were assessed through parent proxy-reports. In Wave 3 (2018–19), a direct assessment of handgrip strength, standing long-jump, and 6-min walk test (6MWT) performance was conducted. After controlling for demographic factors, results of mediation analyses revealed that (a) Wave 1 SES predicted Wave 3 long-jump and 6MWT performance; (b) child physical activity level in Wave 2 mediated the relation between Wave 1 SES and standing long-jump performance in Wave 3; and (c) recreational parent–child activities and child screen time in wave 1 mediated the relation between Wave 1 SES and 6MWT performance in Wave 3. Our findings suggest that the type and frequency of early-life activities play a role in the graded association between childhood SES and physical fitness in adolescence.

Assessment of Physical Activity Indicators for Children and Youth in Ethiopia: Evidence from the Global Matrix 3.0 Study (2017-2018)

Background

Regular physical activity is vital for children’s health, well-being, and development. However, evidence is scant about physical activity indicators for children and youth in Ethiopia. This study aimed to assess physical activity indicators among children and youth in Ethiopia.

Methods

This study was conducted as part of the Active Healthy Kids Global Alliance’s “Global Matrix 3.0” which included 49 countries. Data were collected from December 2017 to April 2018. The country research team included different disciplines related to physical activity. Data were retrieved from pre-reviewed literature, government policy documents, and an expert interview panel. Data were analyzed using the ten physical activity indicators for children and youth. The grading system was done through a harmonized process and the standard grading rubric of the Global Matrix 3.0 study ((A = ≥ 80%, B = 60%–79%, C = 40%–59%, D = 20%–39%, F = < 20%, INC = incomplete data).

Results

For the overall physical activity indicator, 28% of children and youth in Ethiopia met the recommended physical activity of 60 min per day which resulted in a “D” grade. Likewise, the school and government indicator received a “D” grade. Almost 32% of schools in Ethiopia had access to infrastructures and multipurpose spaces for physical activity including outdoor play. The government policy partially existed in the non-communicable diseases agenda but had less focus on children and youth. The active play indicator scored the highest grade of “B.” About 71% of children and youth were involved in active play for at least 2 h a day before, during, and after school. About 50% of children and youth were engaging in organized sport participation, and this indicator was graded a “C.” Similarly, 48% of children and youth walked to and from school as a means of active transportation resulting in a “C” for this indicator. Three indicators (sedentary behavior, family and peers, and community and environment) were graded as an “F.” Approximately 8% of children and youth were living in communities and environments that did not support opportunities for physical activity. Only 13% of children and youth spent less than 2 h per day in sedentary screen time. There was no adequate information to grade the physical fitness indicator.

Conclusion

This study showed that Ethiopian’s children and youth have received low grades for majority of physical activity indicators. Therefore, urgent actions should be taken by the government, policymakers, researchers, and key stakeholders to address the suggested priority areas.

Global Matrix 3.0 Physical Activity Report Card Grades for Children and Youth: Results and Analysis From 49 Countries

BACKGROUND

Accumulating sufficient moderate to vigorous physical activity is recognized as a key determinant of physical, physiological, developmental, mental, cognitive, and social health among children and youth (aged 5-17 y). The Global Matrix 3.0 of Report Card grades on physical activity was developed to achieve a better understanding of the global variation in child and youth physical activity and associated supports.

METHODS

Work groups from 49 countries followed harmonized procedures to develop their Report Cards by grading 10 common indicators using the best available data. The participating countries were divided into 3 categories using the United Nations' human development index (HDI) classification (low or medium, high, and very high HDI).

RESULTS

A total of 490 grades, including 369 letter grades and 121 incomplete grades, were assigned by the 49 work groups. Overall, an average grade of "C-," "D+," and "C-" was obtained for the low and medium HDI countries, high HDI countries, and very high HDI countries, respectively.

CONCLUSIONS

The present study provides rich new evidence showing that the situation regarding the physical activity of children and youth is a concern worldwide. Strategic public investments to implement effective interventions to increase physical activity opportunities are needed.

Report Card Grades on the Physical Activity of Children and Youth Comparing 30 Very High Human Development Index Countries

BACKGROUND

To better understand the childhood physical inactivity crisis, Report Cards on physical activity of children and youth were prepared concurrently in 30 very high Human Development Index countries. The aim of this article was to present, describe, and compare the findings from these Report Cards.

METHODS

The Report Cards were developed using a harmonized process for data gathering, assessing, and assigning grades to 10 common physical activity indicators. Descriptive statistics were calculated after converting letter grades to interval variables, and correlational analyses between the 10 common indicators were performed using Spearman's rank correlation coefficients.

RESULTS

A matrix of 300 grades was obtained with substantial variations within and between countries. Low grades were observed for behavioral indicators, and higher grades were observed for sources of influence indicators, indicating a disconnect between supports and desired behaviors.

CONCLUSION

This analysis summarizes the level and context of the physical activity of children and youth among very high Human Development Index countries, and provides additional evidence that the situation regarding physical activity in children and youth is very concerning. Unless a major shift to a more active lifestyle happens soon, a high rate of noncommunicable diseases can be anticipated when this generation of children reaches adulthood.

Results from the Hong Kong's 2018 report card on physical activity for children and youth

BACKGROUND/OBJECTIVE

The Active Healthy Kids 2018 Hong Kong Report Card provides evidence-based assessment across 12 indicators of physical activity behaviors, sleep, and related community and government initiatives for children and youth.

METHODS

The systematic development process provided by the Active Healthy Kids Global Alliance was used. The best available data from the past 10 years were reviewed by a panel of experts. According to predefined benchmarks, letter grades were assigned to 12 indicators (Overall Physical Activity, Organized Sport Participation, Active Play, Active Transportation, Sedentary Behaviors, Physical Fitness, Sleep, Family, School, Community and Environment, Government, and Obesity).

RESULTS

Three of the five activity behaviors received C- or C grades: Overall Physical Activity (C-), Sedentary Behaviors (C-), and Organized Sport Participation (C). Active Transportation was graded B + . Same to the 2016 Hong Kong Report Card, Active Play could not be graded. School and Government were graded C. Family and Community and Environment was graded D- and B, respectively. Three new indicators were added after the 2016 Report Card and they were graded from C- (Sleep) to D (Physical Fitness) or D- (Obesity).

CONCLUSIONS

Children and youth in Hong Kong have low physical activity and physical fitness levels and high sedentary behaviors despite a generally favorable community environment. A high prevalence of obesity and low levels of family support warrant more public health action. Researchers should address the surveillance gap in active play and peer support.
