The Relationship between Technology Use and Physical Activity among Typically-Developing Children

Changes in the Average Body Mass Index of Fifth- and Sixth-Grade Korean Elementary School Students: The Role of Physical Education in Student Health

This study aimed to emphasize the importance of physical education in maintaining sufficient physical activity by examining the average BMI of fifth- and sixth-grade elementary school students in Korea over multiple years. This study investigated changes in the average BMI of fifth- and sixth-grade elementary school students in Korea. It provided foundational data to suggest the role of physical education in student health and set future directions. The 2019-2021 Physical Activity Promotion System (PAPS) of the Korean Ministry of Education was used. Data corresponding to fifth- and sixth-grade students (124,693 from 2019, 126,226 from 2020, and 117,809 from 2021) in 1208 elementary schools in Korea were collected. Repeated measures ANOVA was conducted for the data analysis. The study findings are as follows: First, the average BMI of fifth- and sixth-grade elementary school students in Korea increased significantly in 2021 compared with 2019 and 2020. Second, changes in the yearly average BMI showed a significant difference depending on gender and grade. Obesity among fifth- and sixth-grade elementary school students in Korea increased steadily during 2019-2021, which may be due to a decrease in students' physical activity. Male students showed a steeper increase regardless of grade. During the study period, limited physical activity at school increased obesity rates. Physical education must play a role in students' health in preparation for future changes.

Comparative Analysis of Physical Activity, Performance-Related Health, and Academic Achievements in 11-to-13-Year-Old Schoolchildren in Qatar

Age-related differences in physical activity (PA), maturity status (PHV), physical performance (PP), and academic achievement (AA) among schoolchildren in Qatar were examined. Sixty-nine students from a school in Doha were categorized into three equal (n = 23) groups: 11-year-old students (U11; male: n = 14), 12-year-old students (U12: male: n = 7), and 13-year-old students (U13: male: n = 11). The testing process comprised a medicine ball throw, Stork balance test, hand grip strength test, the T-half test (PP), GPA in Arabic, mathematics, science (AA), International Physical Activity Questionnaire Short Form (PA), and Moore's equations (PHV). Relevant age-related differences (p < 0.001) were identified in mathematics, science, the T-half test, maturity, and arm span. Notably, differences between adjacent age groups were evident between U11 and U12, concerning arm span, maturity, mathematics, and science, and between U12 and U13 (the T-half test, mathematics, science). Concerning AP, the performance maxima were calculated for U12 (mathematics, science) and U11 (Arabic). Regarding PP, performance maxima were only observed for U13. Except for the moderate level, the highest levels of PA were detected in U13. Maturity status and anthropometric parameters did not differ significantly between age groups. However, AA demonstrated the most notable age-related differences. Specifically, mathematics showed substantial differences between adjacent age groups.

Effectiveness of Back care education Programme among school children: a systematic review of randomized controlled trials

STUDY DESIGN

Systematic review of Randomised controlled trials.

OBJECTIVES

With the increasing incidence of back pain among children and its untold implications to their future, back education tailored in an effective way would be indicated. However literature appears unsettled. This study aims to review available literature to determine the effect of school-based back education in preventing and managing low back pain in school children.

METHODS

Randomized controlled trials carried out on elementary and secondary school children of ages 6 to 18 years and published in English language were included. Back education taught in hospitals or other settings were excluded. Primary outcome was back pain prevalence and secondary outcomes were constituted from the study characteristics of selected studies which includes: back behavior, knowledge, postural habits, physical activity, fear-avoidance beliefs, back pack carriage, pain intensity, skills and self efficacy. Databases searched were PEDro, HINARI, PubMed, Cochrane, and Google Scholar. Available stiudies from 2000 to March 2022 were retrieved. Quality of studies were assessed using the PEDro scale. Obtained studies were descriptively analyzed.

RESULTS

A total 8420 studies were retrieved and 8 studies (with 1239 participants) were included in this review. Four studies each assessed back knowledge and back behavior, and two assessed back pain prevalence. There were improvements in back knowledge and back behaviour, but effectiveness of back care education on back pain prevalence was not conclusive. Forms of education used involved the indirect method of conditioning the environment and the direct method which made use of theory, practical lessons and educational books and materials.

CONCLUSION

Back care education programmes in schools are effective in improving back care knowledge, behavior and reduction in low back pain frequency. Reduction in back pain prevalence is not conclusive. Back care education could be incorporated as part of schools' education programmes. Limitations include exclusion of non English language studies and inconsistent outcome measures.

Next Generation Weight Loss Drugs for the Prevention of Cancer?

Background: Western populations are losing the battle over healthy weight management, and excess body weight is a notable cancer risk factor at the population level. There is ongoing interest in pharmacological interventions aimed at promoting weight loss, including GLP-1 receptor agonists (GLP-1RA), which may be a useful tool to stem the rising tide of obesity-related cancers. Purpose: To investigate the potential of next generation weight loss drugs (NGWLD) like GLP-1RA in population-level chemoprevention.Research Design: We used the OncoSim microsimulation tool to estimate the population-level reductions in obesity and the potentially avoidable obesity-related cancers in Canada over the next 25 years.Results: We estimated a total of 71 281 preventable cancers by 2049, with 36 235 and 35 046 cancers prevented for females and males, respectively. Among the 327 254 total projected cancer cases in 2049, 1.3% are estimated to be preventable through intervention with NGWLD.Conclusions: Pharmacologic intervention is not the ideal solution for the obesity-related cancer crisis. However, these agents and subsequent generations provide an additional tool to rapidly reduce body weight and adiposity in populations that have been extremely challenging to reduce weight with standard diet and exercise approaches. Additional research is needed around approaches to prevent initial weight gain and maintain long-term weight loss.

Leisure screen time predicts free sugar consumption in children

OBJECTIVE

This study aimed to investigate free sugar consumption (FSC) in relation to leisure screen time in children.

METHODS

Cross-sectional data of 424 healthy Saudi children ages 6 to 12 y were included in this study. Data pertaining to sociodemographic characteristics and leisure screen time (including time spent viewing TV, gaming, and use of electronic devices [e.g., computer, tablet, and smartphone]) in children were collected from mothers via an online questionnaire. A phone interview was later conducted with the mother and child to assess FSC using a previously validated 40-item food frequency questionnaire.

RESULTS

Our data found that a large proportion of children exceeded the maximum limit of screen time recommended for children, of ≤2 h/d (61.7%; n = 262). Child and maternal ages and child's birth order among siblings were significantly associated with the duration of leisure screen time (screen time within the recommendation of ≤2 h/d versus screen time that exceeded the recommendation; P < 0.050). Exceeding the recommendation of screen time predicted an increase of 8.96 g/d of FSC from liquid foods, 10.7 g/d of FSC from solid foods, and 19.3 g/d of total FSC.

CONCLUSIONS

Exceeding the recommendation of screen time is associated with greater FSC in children. Future interventions should be directed toward restricting screen time and FSC in children.

Assessment of the Correlation between the Levels of Physical Activity and Technology Usage among Children with Down Syndrome in the Riyadh Region

Background: Children with Down Syndrome (C-DS) have language, cognitive and communication difficulties, in addition to consistent physical inactivity that contributes to poor health and higher-disability-adjusted life years. The purpose of this study was to determine the correlation between the use of electronic technology and levels of physical activity in C-DS in the Riyadh region of Saudi Arabia. Methods: A cross-sectional study was conducted with 49 mothers, where each had a child (6-12 years of age) with Down Syndrome (DS), and who were recruited using purposive sampling from three DS centers in Riyadh, Saudi Arabia. The Children's Physical Activity Questionnaire and Research Questionnaire on the Impact of Technology on Children were used. Descriptive statistics were used to describe the demographics. Pearson's correlation, Student's t-test and the Chi-square test were used to assess the association between technology use, physical activity levels and socio-demographic variables. Results: There was no significant correlation between physical activity and the use of technology by C-DS. However, there was a negative correlation between a high level of physical activity and technology use (R = -0.037). Although, no significant correlation between the mother's characteristics and technology use was found; there was a significantly positive correlation (p = 0.05) between the education level of mothers and the technology use by C-DS. Nonetheless, there was no association between the physical activity level and the gender of the child with DS. Conclusions: This study found that no significant relationship exists between the use of electronic gadgets and the level of physical activity in C-DS.

Cross-Sectional Associations between Playing Sports or Electronic Games in Leisure Time and Life Satisfaction in 12-Year-Old Children from the European Union

Leisure time activities in childhood may have a crucial role in the development of subjective well-being. Nevertheless, more research is needed with cross-national samples concerning the differential effects of lifestyles on life satisfaction. The aim of this cross-sectional study was to analyze the associations between the frequency of playing sports/exercise or playing electronic games on life satisfaction in a sample of 12-year-old children from nine countries from the European Union. The data used in this publication come from the third wave of the Children’s Worlds project, an international survey of children’s lives and well-being whose administration started in 2017. The sample was composed of 10,626 children (50.9% boys) from Estonia, Belgium, Croatia, Hungary, Italy, Malta, Poland, Romania, and Spain. They completed the Student Life Satisfaction Scale and answered two questions to assess the frequency of playing sport or exercise, and the frequency of playing electronic games. The results indicated notable scores in life satisfaction in all participating countries. The results showed some differences between boys and girls, and among the countries, in the frequency of sport practice and electronic games in the leisure time, as well as in the overall level of life satisfaction. The results also underlined that sport practice had a greater positive effect on life satisfaction than the use of electronic games. Thus, this study highlights the need to design programs to promote sport practice in leisure time for 12-year-old children in Europe, in order to protect their subjective well-being.

Energy Intake from Healthy Foods Is Associated with Motor Fitness in Addition to Physical Activity: A Cross-Sectional Study of First-Grade Schoolchildren in Japan

Childhood motor fitness is important for the physical and mental health of children and the prevention of future lifestyle diseases. This study aimed to investigate how energy intake from healthy foods and physical activity are associated with motor fitness among first-grade children. First-grade children (aged 6–7 years) attending three public elementary schools in Tokyo, Japan (n = 884), participated in this cross-sectional study. Self-administered questionnaires were distributed, which focused on lifestyle habits and required completion of a 1-day dietary record of meals that children ate at home. School lunch consumption was also assessed. Motor fitness was assessed by the New Physical Fitness Test (NPFT). Multiple regression analysis was used to investigate the association of the amount of energy from healthy foods and physical activity with NPFT scores. NPFT scores were positively correlated with involvement in after school exercise classes, playing outside (in boys only), and total energy intake. Energy intake from healthy foods showed a positively associated with NPFT scores (boys, β = 0.120, p = 0.011; girls, β = 0.140, p = 0.004), while energy intake from unhealthy foods did not. Energy intake from healthy foods was associated with motor fitness in children in addition to physical activity.

Familial and Parental Predictors of Physical Activity in Late Adolescence: Prospective Analysis over a Two-Year Period

Children’s health behaviors are highly influenced by their parents and family. This study aimed to prospectively evaluate the parental/familial factors associated with physical activity levels (PALs) among older adolescents. The participants were 766 adolescents, who were prospectively observed at baseline (when they were 16 years of age), at first follow-up measurement (FU1; 17 years of age), and second follow-up measurement (FU2; 18 years of age). Sociodemographic factors (age, gender, socioeconomic status, and sport participation) and parental/familial variables were evaluated at baseline. PALs (evidenced by the Physical-Activity Questionnaire-for-Adolescents) were prospectively evidenced at baseline, FU1, and FU2. Factorial analysis of variance for repeated measurements showed a significant decrease in PALs during the study course (F = 83.05, p < 0.001). Sport participation and male gender were significant predictors of PALs at baseline, FU1, and FU2. Logistic regression, controlled for sport participation and male gender, evidenced paternal education as a significant predictor of baseline PALs. Parental conflict was a significant predictor of PALs in all three testing waves. The significant influence of paternal education on the children’s PALs existed from younger adolescence until the age of 17 years. The association between parental conflict and PALs developed in older adolescence. These results should be used in the development of specific and targeted interventions aimed at the improvement of PALs and a reduction of sedentarism in youth.
