Summary: The study suggests that regular TV viewing during early childhood is associated with an increased risk of type 2 diabetes in adult women, especially for those who watched TV for long hours at ages 5-10. Adult BMI partly explains this association.

Summary: Projectors and large TV screens are commonly used in modern teaching, but there are concerns about the potential eye hazards of eLearning. A quantitative study was conducted to determine the permissible viewing time for using projectors and large TV screens. Surprisingly, the large TV screens were found to be more eye-friendly and could allow for a longer viewing time, likely due to their higher resolution. Two dilemmas were observed in eLearning, with those sitting in the front experiencing higher illuminance and shorter viewing time, while those in the back requiring a larger font size for clear visibility. Using orange text on a black background was suggested to ensure both viewing clarity and a longer permissible viewing time. These findings can help educators and e-display users apply display tools safely.

Summary: The study found that regardless of sedentary TV viewing, boys and girls with low cardiorespiratory fitness levels had higher cardio-metabolic risk. However, the association between low cardiorespiratory fitness levels and higher cardio-metabolic risk was attenuated after adjusting for confounding factors such as adiposity.

Summary: This study investigated the relationships between executive function (EF), physical activity (PA), and associated factors in low-income preschoolers. The results highlighted moderate PA and preterm birth as the most important variables in the network. Future interventions should focus on increasing moderate PA, with special attention to preterm children.

Summary: This systematic review examined the measurement properties of self-and proxy-reported questionnaires measuring 24-hour movement behaviors in children and adolescents. The review included 29 studies and 37 questionnaires, and assessed the content, convergent and criterion validity, reliability, measurement error, and bias of each questionnaire. The findings revealed insufficient measurement properties and the lack of questionnaires considering the 24-hour movement behavior paradigm. Better questionnaires are needed to improve monitoring and surveillance systems in this population.

Summary: This study aimed to establish an equation to predict the results of the six-minute walk test (6MWT) and observe its agreement with measured values. The results showed a strong correlation between the 6MWT and the two-minute step test (2MST), and the regression equation derived from multiple linear regression showed good agreement with measured values when the 6MWT was below 600 meters. Therefore, the 2MST can serve as an alternative approach when time and space are limited.

Summary: This investigation aimed to describe the current physical fitness (PF) status of Portuguese youth, compare secular trends from 2008 and 2018, and establish updated age- and sex-specific percentile values for distinct PF tests. In 2018, boys surpassed girls in multiple PF tests, while girls showed improvement in flexibility. The present investigation provides new and updated PF percentile curves for Portuguese youth.

Summary: This cross-sectional study in Brazil aimed to examine the association between parental physical activity and social support with adolescents meeting physical activity recommendations. The results showed that for boys, having parents who always attend and meet the physical activity recommendations were associated with meeting the recommendations. For girls, having parents who sometimes encourage them was associated with lower odds of meeting the recommendations. These findings can inform future interventions targeting physical activity behaviors in adolescents.

Summary: There is an increasing use of naturalistic paradigms in investigating human brain function. Functional near-infrared spectroscopy (fNIRS) is a suitable modality for naturalistic investigations, but specific statistical analysis is needed. In this study, an exploratory graph-centrality-based approach was used to examine spatiotemporal similarities in fNIRS signals of typically developing children watching a neuroimaging movie. The results suggest the feasibility of investigating brain function in naturalistic fNIRS during development using centrality graph-based measures.

Summary: This study investigated the relationship between mental difficulties, cognitive function, and factors such as physical fitness, exercise, obesity, and socio-demographic factors in children. The results showed that age and physical fitness moderate the relationship between cognitive function and moderate-to-vigorous physical activity, while the 24-hour movement components influence the relationship between cognitive function and mental difficulties. Centrality measures from network analysis suggest that physical fitness, moderate-to-vigorous physical activity, and screen time are crucial nodes for future interventions.

Summary: This study examined the association between motor skill competence and BMI in a multi-country sample of preschoolers. The results showed a negative correlation between motor skill competence and BMI percentiles, which was more significant in children with higher BMI. Each raw score point increase in motor skill competence was associated with a reduction in BMI of 8.9%, 6.8%, and 5.1% for those preschoolers at the 97th BMI percentile onwards.

Summary: This study aimed to evaluate the effect of high-intensity interval training (HIIT) and moderate-intensity of continuous training (MICT) on overweight adolescents. The results showed that HIIT reduced body mass index, waist-to-height ratio, low-density lipoprotein, and C-reactive protein, while increasing physical fitness. MICT reduced high-density lipoprotein, while increasing physical fitness. In the control group, improvements were seen in body composition and heart rate. Individual responsiveness was observed in inflammatory process and physical fitness. The interventions with exercises were effective in improving adiposity, metabolic health, and physical fitness in overweight adolescents.
