24-h movement behaviours in Spanish youth before and after 1-year into the covid-19 pandemic and its relationship to academic performance.

Most studies have shown a decline in the adherence to 24-Hour Movement Guidelines because of Covid-19 lockdown. However, there is little evidence regarding changes 1-year after the pandemic in these guidelines and their possible impact on academic performance. The study aims were: (1) to examine the possible changes in 24-Hour Movement Guidelines for youth (i.e., at least 60 min per day of moderate-to-vigorous physical activity, ≤ 2 h per day of recreational screen time, and 9 to 11 h of sleep per day for children and 8 to 10 h for adolescents) before and after 1-year into the Covid-19 pandemic, and (2) to examine the possible changes in the relationship between 24-Hour Movement Behaviours (physical activity, screen time, and sleep duration) and academic performance before and after 1-year into the Covid-19. This is a repeated cross-sectional study in two different samples of young Spanish at different times. Firstly, a total of 844 students (13.12 ± 0.86; 42.7% girls) completed a series of valid and reliable questionnaires about physical activity levels, recreational screen time, sleep duration and academic performance before Covid-19 pandemic (March to June 2018). Secondly, a different sample of 501 students (14.39 ± 1.16; 55.3% girls) completed the same questionnaires 1-year after Covid-19 pandemic (February to March 2021). Adherence to the three 24-Hour Movement Guidelines was significantly lower 1-year after into the Covid-19 pandemic (0.2%) than before the pandemic (3.3%), while adherence to none of these three recommendations was significantly higher 1-year after the Covid-19 pandemic (66.3%) than before the pandemic (28.9%). The positive relationship between physical activity levels and academic performance was no longer significant after 1-year into Covid-19 pandemic (ß = - 0.26; p < 0.001). 1-year after Covid-19 pandemic, the relationship between recreational screen time (ß = - 0.05; p > 0.05) and sleep duration (ß = 0.05; p < 0.001) with academic performance did not change compared to pre-pandemic. The results suggest that 24-Hour Movement Behaviours have worsened among young people 1-year after Covid-19 pandemic compared to pre-pandemic period. Moreover, the physical activity benefits associated in terms of academic performance seem to have disappeared because of the Covid-19 pandemic. Therefore, there is a public health problem that requires priority and coordinated action by schools, policy makers, and researchers to mitigate the adverse effects of the pandemic on 24-Hour Movement Behaviours.

Meeting 24 h Movement Guidelines and Health-Related Quality of Life in Youths during the COVID-19 Lockdown

Limitations in the use of public spaces have impacted the frequency and duration of movement behaviours (physical activity, sedentary behaviour, sleep) and outdoor activities of children and adolescents. Whether pandemic-induced changes in movement behaviours are related to the health-related quality of life (HRQoL) of children and adolescents is unknown. The aim of the current study was to examine the association between meeting 24 h movement guidelines and HRQoL during the COVID-19 lockdown among children and adolescents. Data from 1099 3–17-year-old children and adolescents from Spain and Brazil were analysed. An online questionnaire was used to collect parent-reported information concerning physical activity, screen time, and sleep duration. For the assessment of HRQoL, the EQ-5D-Y proxy version was used. The highest prevalence of reported problems was related to the 'worries/sadness/unhappiness' factor, where 36.3% of participants declared to have at least 'some problems'. Participants meeting the 24 h guidelines had a higher HRQoL score compared with those who did not (91.9 ±2.5 vs. 84.3 ±0.5, respectively;p < 0.05). The current study shows that children and adolescents that met 24 h movement guidelines presented a higher HRQoL during the COVID-19 lockdown, providing support for the promotion of healthy movement behaviours-especially during a pandemic.

Is adherence to 24-Hour Movement Guidelines associated with a higher academic achievement among adolescent males and females?

OBJECTIVES: This study aims to examine the independent and combined associations of 24-Hour Movement Guidelines for physical activity, screen time, and sleep duration with academic achievement in adolescent males and females. DESIGN: Cross-sectional study. METHODS: 1290 Spanish adolescents (565 females), aged 11 to 16 years (13.06 ±â€¯0.84), participated in this study. Self-reported physical activity, screen time, and sleep duration questionnaires were assessed. Academic achievement was calculated as an average score of the adolescents'' grades in first language (Spanish), first foreign language (English), and mathematics subjects. A multiple linear regression model was used to examine the association between meeting 24-Hour Movement Guidelines and academic achievement. Covariates included age, sex, socioeconomic status, body mass index, and cardiorespiratory fitness. RESULTS: Not meeting any of the three 24-Hour Movement Guidelines was associated with lower academic achievement in the whole sample (p < 0.001). Meeting physical activity and sleep duration guidelines, both independently and together, was associated with higher academic achievement in the whole sample (p < 0.001). Meeting at least two recommendations was associated with higher academic achievement in males (p < 0.01). However, trend analysis revealed that participants who met two or three recommendations had higher academic achievement compared to those who met one or none of these recommendations (p < 0.05). All these results were similar for males and females. CONCLUSIONS: Our findings suggest the importance of promoting more than one 24-Hour Movement Guidelines, mainly physical activity and sleep duration, which seems to contribute positively to increased academic performance in adolescents.

The Role of Physical Activity in the Relationship between Satisfaction with Life and Health-Related Quality of Life in School-Age Adolescents.

(1) Background: Adolescence is a critical stage in the development of healthy habits. In this regard, physical activity has emerged as a useful tool to improve satisfaction with life and health-related quality of life in adolescents. Therefore, the aim of the present study was to examine the mediating role of physical activity in the relationship between satisfaction with life and health-related quality of life in adolescent boys and girls. Also, we aimed to investigate the differences between sexes in the HRQoL, physical activity level, and satisfaction with life. (2) Methods: A total of 297 adolescents, ranging in age from 11 to 12 years (11.46 ± 1.63), participated in this cross-sectional study. The Satisfaction with life scale, Physical activity Questionnaire for Adolescents and the KIDSCREEN-10 questionnaires were employed. (3) Results: The estimated indirect effect showed that physical activity level was a mediator of the positive effect of satisfaction with life on health-related quality of life (ß = 0.105, 95% CI = 0.031; 0.202). However, the index of moderated mediation showed that sex is not a significant moderator of the mediating role of physical activity in the relationship between satisfaction with life and HRQoL (ß = -0.033, 95% CI = -0.023, 0.136). Furthermore, significant differences in satisfaction with life were found, with girls manifesting lower values (p-value = 0.026). (4) Conclusion: This study shows the importance of physical activity during adolescence and the association of this behavior with the health-related quality of life of adolescents.

Health Promotion through Movement Behaviors and Its Relationship with Quality of Life in Spanish High School Adolescents: A Predictive Study.

A growing number of studies have highlighted the health benefits of high physical activity, low screen time, and optimal sleep duration among school-age children and adolescents. Objective: The present study proposes to examine the individual and combined association between movement behaviors (physical activity, screen time, and sleep time) and quality of life in boys and girls. Method: A total of 319 Spanish primary and secondary school students participated in the study. Physical activity, screen time, sleep duration, and quality of life were evaluated. Results: Descriptive, correlation, and regression analyses were carried out in order to improve knowledge about health-related behaviors for all participants. The results found significant positive associations between physical activities and sleep time with quality of life. Finally, the regression models showed that physical activity scores predict quality of life, especially in children. It is concluded that movement behaviors are important in association with quality of life. Likewise, the impact of physical activity on the quality of life is highlighted as the main behavior in the prediction of the quality of life for a population of school adolescents.
