2022 French Report Card on Physical Activity and Sedentary Behaviors in Children and Youth: From Continuous Alarming Conclusions to Encouraging Initiatives.

BACKGROUND: Scientific evidence and public health reports keep highlighting the continuous and alarming worldwide progression of physical inactivity and sedentary behaviors in children and adolescents. The present paper summarizes findings from the 2022 French Report Card (RC) on physical activity for children and youth and compares them to the 2016, 2018, and 2020 RCs. METHODS: The 2022 edition of the French RC follows the standardized methodology established by the Active Healthy Kids Global Matrix. Ten physical activity indicators have been evaluated and graded based on the best available evidence coming from national surveys, peer-reviewed literature, government and nongovernment reports, and online information. The evaluation was also performed in children and adolescents with disabilities. Indicators were graded from A (high level of evidence) to F (very low level of evidence) or INC for incomplete. RESULTS: The evaluated indicators received the following grades: overall physical activity: D-; organized sport participation and physical activity: C; active play: F; active transportation: C; sedentary behaviors: D-; family and peers: D; physical fitness: C; school: C-; community and the built environment: F; government: B. CONCLUSIONS: While this 2022 French RC shows progression for 7 out of the 10 indicators considered, it also underlines the continuous need for actions at the local, regional, and national levels to develop better surveillance systems and favor a long-term improvement of youth movement behaviors.

Dissemination, Implementation, and Evaluation of an Effective School-Based Intervention to Promote Physical Activity in Adolescents: A Study Protocol.

Adolescents around the world do not engage in sufficient physical activity and the Spanish context is no exception. Understanding the educational context as a complex system, school-based multi-level and multi-component interventions seem to be an effective strategy to reverse this trend. Moreover, a co-creational approach seems to facilitate the mobilization of community partnerships and the engagement of stakeholders in the intervention process. This study aims to describe the dissemination, implementation, and evaluation process of an effective school-based intervention program in another setting using the replicating effective programs framework and a co-participatory approach. This study will be conducted in two Spanish secondary schools located in the region of Aragon (experimental vs. control school) in a sample of adolescents in the second grade (13-14 years old). To evaluate the effectiveness, different health behaviors such as physical activity, sleep, sedentary time with screens, nutrition, and psychosocial variables will be quantitatively measured at baseline and after the implementation of the intervention. Qualitative methods will also be used to better understand the implementation process and the co-creation approach, as well as to provide insights into the sustainability of the intervention program. The current study has the potential to provide strong information about the dissemination, implementation, and evaluation process of school-based programs to promote healthy behaviors among adolescents.

Accelerometer-Based Physical Activity Assessment During Intermittent Conditions: Effect of Epoch Length on Energy Expenditure Estimate.

Purpose: This study analyzed the effect of epoch length on energy expenditure (EE) estimates and on the moderate-to-vigorous physical activity (MVPA) measure obtained from EE estimates during accelerometer-based assessment. Methods: Ten active students exercised on a treadmill for four 5-min bouts, using two effort intensities (running and walking) and two physical activity (PA) patterns (continuous or intermittent) wearing an accelerometer. The criterion measure of EE was achieved using indirect calorimetry. Data obtained from the accelerometer were reintegrated into 1-sec, 10-sec, 30-sec and 60-sec epochs. Results: During the running intermittent condition, EE and MVPA estimates from the accelerometer were no different from the criterion measure with 30- and 60-sec epoch lengths but they were different with shorter epoch lengths. During the walking intermittent condition, no difference was observed between EE estimates and the criterion measure, regardless of the epoch length. During the running continuous condition, EE estimated from the accelerometer was significantly lower than the EE obtained with the criterion measure, regardless of the epoch length. During the walking continuous condition, no difference was observed. Conclusion: During the intermittent running condition, longer epoch lengths gave the best EE and MVPA estimates. This conclusion is contrary to the current general view that shorter epochs are the most accurate for PA assessment. However, PA estimates are closer to an external load estimates whereas EE estimates are closer to the internal load estimate. Depending on the objective of their study, researchers should be aware of these findings.

Impact of the COVID-19 confinement on movement behaviors among French young children: the ONAPS national survey.

BACKGROUND: The present study examines the effects of the COVID-19 confinement on healthrelated behaviors (physical activity, sedentary behaviors) of young French children. METHODS: Parents of 348 French children under 6 years of age completed an online survey launched during the first days of the initial COVID-19-related confinement. They were asked to indicate whether their kids increased, decreased or maintained their physical activity level, time spent in sedentary behaviors, and sleep time. Information regarding the configuration of their home environment (access to outdoor facilities, implantation area) and lifestyle habits (solitary activity, parents' solicitation; nap time; night waking episodes and night duration) were also collected. RESULTS: A total of 25.0% of the children were reported to decrease, 24.7% maintained and 50.3% increase their physical activity during the confinement. Greater proportions of kids who had access to a collective (51.4%) or individual (53.7%) outdoor area increased their physical activity. Regardless of the housing situation (urban, suburban or rural) or access to outdoor facilities, the majority of children increased their screen time (60.4%). Two-thirds (66.7%) of parents reported nap time remained unchanged for their kids. Fifty-one percent of parents admitted a link between teleworking and their kids' screen time. CONCLUSIONS: Health behaviors were differentially impacted in very young kids during a confinement period. Importantly, a majority of parents admitted a causal effect of telecommuting on their kids' screen exposure. The present results also show that the proneness to increase physical activity during confinement is positively related to access to a favorable outdoor environment.

France's 2020 Report Card on Physical Activity and Sedentary Behaviors in Children and Youth: Results and Progression.

BACKGROUND: There is an alarming and constant worldwide progression of physical inactivity and sedentary behaviors in children and adolescents. The present paper summarizes findings from France's 2020 Report Card on physical activity for children and youth, comparing its results to its 2 previous editions (2016 and 2018). METHODS: France's 2020 Report Card follows the standardized methodology established by the Active Healthy Kids Global Matrix, grading 10 common physical activity indicators using the best available evidence. The grades were informed by national surveys, peer-reviewed literature, government and nongovernment reports, and online information. RESULTS: The expert panel awarded the following grades: Overall Physical Activity: D; Organized Sport Participation and Physical Activity: C-; Active Play: INC; Active Transportation: C-; Sedentary Behaviors: D-; Family and Peers: D-; Physical Fitness: D; School: B-; Community and the Built Environment: F; Government: C. CONCLUSIONS: This 2020 edition of France's Report Card again highlights the alarming levels of physical activity and sedentary behaviors among French children and adolescents, calling for the development of effective national action. It also draws attention to the particular deleterious effects of the COVID-19 confinement on youth's movement behaviors, which significantly worsened the situation.

Effects of an Intervention to Promote Physical Activity and Reduce Sedentary Time in Disadvantaged Children: Randomized Trial.

BACKGROUND: In our society, children are particularly vulnerable to physical inactivity and excessive sedentary time (ST). The aim of this study was to evaluate the effectiveness of a school-based intervention designed to promote physical activity (PA) and reduce ST in 6- to 10-years-old children from a disadvantaged neighborhood. METHODS: The first intervention of this randomized trial was carried out in School 1 in 2017/2018 and 2018/2019, School 2 benefited from the same intervention in 2018/2019. Baseline assessments were realized using accelerometers prior to the intervention (T1-T2), after the first intervention (T3) and after the second intervention (T4). School-based actions targeted children, parents, teachers, physical, and organizational environment of school and politics. The chi-square test of independence was used to analyze the evolution of the moderate and vigorous physical activity (MVPA) and ST. RESULTS: For School 1, an increase in the percentage of very active children (over 40 minutes MVPA/day) and of having a very low ST (less 240 minutes/day) (p = .00) was found. No further evolution was revealed during the intervention (T2-T3) and 1 year after (T3-T4). For School 2, similar effects on PA and ST were found at T3 (p < .05). CONCLUSIONS: Positive effects occurred before the intervention in each school and then remained stable.

School-Based Multicomponent Intervention to Promote Physical Activity and Reduce Sedentary Time of Disadvantaged Children Aged 6-10 Years: Protocol for a Randomized Controlled Trial.

BACKGROUND: In our modern society, physical activity (PA) is decreasing and sedentary time (ST) is increasing, especially for children from disadvantaged neighborhoods. School-based interventions to promote PA and decrease ST are therefore required among this population in order to change children's lifestyle habits. Moreover, attentional capacities and academic achievement can be enhanced by chronic PA during childhood. The relationships between these variables have been poorly studied with this population. OBJECTIVE: The objective of this study is to present the rationale and methods for a randomized controlled trial among 6-10-year-old children with low socioeconomic status that will (1) evaluate the effectiveness of a school-based intervention designed to promote PA and reduce ST and (2) study the relationships between PA, ST, motor skills, attentional capacities, and academic achievement. METHODS: A randomized controlled trial was conducted in 2 eligible primary schools. During academic year 2016-2017, 1 school was randomly assigned as the experiment one and the other was assigned as the control one. Five assessments times were used: baseline (T1 [November 2016] to T2 [June 2017]), follow-up (T3 [November 2017] to T4 [June 2018]), and final assessment (T5 [June 2019]). The school-based intervention included various components on different levels of the socioecological model: (1) curriculum-based program for children; (2) sensitization workshops and newsletters for parents; (3) training workshops for teachers; (4) environmental adaptation of playgrounds and reorganization of recess time; (5) time adaptation of lunch breaks; and (6) collaboration with political groups. PA, ST, motor skills, and attentional capacities were evaluated and academic achievement was recorded. RESULTS: The presented intervention and its different assessments have been successfully implemented. In order to achieve the 2 objectives of this randomized controlled trial, data analyses are about to be completed. CONCLUSIONS: The implementation of this randomized controlled trial can help to determine effective strategies to promote PA in the context of increasing prevalence of physical inactivity among children with sedentary lifestyle which will be useful for researchers, stakeholders, and public policy makers. TRIAL REGISTRATION: ClinicalTrials.gov NCT03983447; https://clinicaltrials.gov/ct2/show/NCT03983447. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR1-10.2196/17815.

Effect of epoch length on intensity classification and on accuracy of measurement under controlled conditions on treadmill: Towards a better understanding of accelerometer measurement.

PURPOSE: The aim of this study was to analyze the effect of epoch length on intensity classification during continuous and intermittent activities. METHODS: Ten active students exercised under controlled conditions on a treadmill for four 5-min bouts by combining two effort intensities (running and walking) and two physical activity (PA) patterns (continuous or intermittent). The testing session was designed to generate a known level of moderate to vigorous PA (MVPA) for each condition. These PA levels were used as criterion measures to compare with the accelerometer measures. Data obtained from the accelerometer were reintegrated into 1-sec, 10-sec, 30-sec and 60-sec epochs. Equivalence testing was used to examine measurement agreements between MVPA values obtained with the different epochs and the reference values. Mean absolute percent errors (MAPE) were also calculated to provide an indicator of overall measurement error. RESULTS: During the intermittent conditions, only the value obtained with the 1-sec epoch was significantly equivalent to the reference value. With longer epochs the difference increased for both intermittent conditions but in an opposite way: with longer epochs, MVPA decreased during walking but increased during running. Regarding the measurement accuracy, the pattern of variations according to the epoch length selected during the intermittent conditions was identical between walking and running: MAPE increased with the increase in epoch length. MAPE remained low only for the 1-sec epoch (7.6% and 2.7% for walking and running, respectively), increased at 31.3% and 34% for the 10-sec epoch and until near 100% with the 30- and 60-sec epoch lengths. CONCLUSION: This study highlighted the misclassification of exercise intensity based on accelerometer measurement and described for the first time the extent and the direction of this misclassification. Moreover, we can confirm that the shorter epochs are more accurate to measure the real exercise intensity during intermittent PA whatever the intensity.

Centre for the Promotion of Physical Activity and Health (CAPAS-City): A Pyrenean Cross-Cultural Structure to Lead the Way in the Design, Implementation, and Evaluation of Multilevel Physical Activity Interventions.

This study describes a Pyrenean cross-cultural structure called Centre for the Promotion of Physical Activity and Health (CAPAS-City) that was created to promote physical activity (PA) in Huesca (Spain) and Tarbes (France). The main aim of this centre is to lead the way in the design, implementation, and evaluation of multilevel PA interventions to improve their efficacy and sustainability inside the city. CAPAS-City responds to the main challenges related to multilevel PA interventions, through six guiding principles: (1) promoting sustainability, (2) playing a leadership role, (3) promoting multisectoral partnerships, (4) using evidence-based strategies, (5) promoting integrated knowledge translation, and (6) using a participatory research approach. Five multilevel PA interventions were designed in both cities by CAPAS-City with these principles in mind. Through the example of the Annual MOT Test adapted to bikes, we also illustrate one practical application of the use of these principles, following the Social-Ecological approach, in which the main agents of influence are involved at different levels to encourage cycling. According to the promising results found in this study, CAPAS-City appears to be a structure that is able to respond to the main needs and challenges of multilevel interventions to increase PA levels in the whole population of both cities.

Sedentary Behaviors by Type of Day and Physical Activity in Spanish Adolescents: A Socio-Ecological Approach.

The aim of this study was to analyze the relationship between TV and computer use, study time, and physical activity, with regard to gender, school, and weekday/weekend. Adolescents (N = 1,609; M age = 14.5 yr., SD = 1.3) reported on physical activity, sedentary behavior, their parents' employment, and environmental factors. The relationship between PA and screen media behaviors was negative on weekdays, while no relationship was found at weekends. Only 30.7% of adolescents met the screen media guidelines on weekdays and 14.6% at weekends. Girls spent more time on study, only showing a positive relationship with physical activity on weekdays. Each type of sedentary behavior has different correlates for weekdays and weekends.

Adolescents' Sedentary Behaviors in Two European Cities.

PURPOSE: The aim of this study was to determine and compare the correlates of objective sedentary behavior (SB) and nonschool self-reported SB in adolescents from 2 midsized cities, 1 in France (Tarbes) and 1 in Spain (Huesca). Stability of objective SB and nonschool self-reported SB were also assessed at different time points during 1 academic year. METHOD: Starting with a total of 829 participants and after applying inclusion criteria, objective SB was assessed for 646 adolescents (Mage = 14.30 ± 0.71 years) with GT3X accelerometers for 7 days at 2 time points. Nonschool self-reported SB was measured for 781 adolescents (Mage = 14.46 ± 0.76 years) at 3 time points by means of a questionnaire. Data were analyzed using multiple regression analysis. RESULTS: Gender and ambient temperature emerged as the main statistically significant correlates in all objective SB models, showing higher objective SB levels in girls and lower objective SB levels when ambient temperature was higher. According to nonschool self-reported SB, a gender effect was found in almost all behaviors. Whereas boys spent more time playing with video games as well as games on their mobile phones, girls spent more time studying and using their computers and mobile phones to communicate with each other. The findings showed a statistically significant city effect on study time (Huesca > Tarbes) and video games and telephone communication time (Tarbes > Huesca). CONCLUSION: Nonschool self-reported SB patterns were different in Huesca and Tarbes. Intervention programs should be adapted to target the reduction of adolescents' SB according to different contexts.

Weekday and weekend physical activity patterns of French and Spanish adolescents.

Adolescents' objectively assessed physical activity (PA) patterns during specific segments of the day remain unclear. In order to develop a clearer understanding this study examined country and gender differences in moderate to vigorous physical activity (MVPA) levels during specific segments of weekdays and weekend days, and explored the contribution of each segment to PA guidelines. Morpho-demographic, socio-economic and PA data were collected from a sample of 829 French and Spanish adolescents (45.0% Spanish; 55.2% females; 14.33±.73 years). Actigraph GT3X accelerometers were worn for seven days to assess adolescents' MVPA for three segments of weekdays (school-travel-time, school-time, and non-school-time), and weekend days (morning-time, afternoon-time and night-time). Data were analysed using multilevel modelling. The most active segments were non-school-time (29.2±17.5 min) and school-time (25.8±14.2 min) during weekdays, and morning-time (28.2±25.8 min) on weekend days. Except for school-time, Spanish adolescents were more significantly active than French adolescents during all segments. Significant gender differences were found in all segments. Country differences highlight the need to recognise cultural contexts that influence adolescents' PA. Common European-wide strategies may be insufficient to increase MVPA levels if cultural variability is not considered. Spanish and French PA intervention programmes should target girls and low-active boys during non-school-time and weekends.

A cross-cultural study of adolescents' physical activity levels in France and Spain.

The goals of this study were (1) to describe and compare levels of physical activity (PA), assessed by accelerometry, of adolescents in two close Spanish and French cities according to gender and period of the week and (2) to assess, with reference to country and gender, the extent to which international PA guidelines were fulfilled. The PA of 401 adolescents (53.37% females) from France and Spain (55.72% French) aged 14.45 ± 0.67 years was assessed with GT3X accelerometers for seven consecutive days to evaluate their habitual levels of moderate to vigorous physical activity (MVPA). Data collection took place from September to December 2010 in six public and state schools in France and Spain. There were significant differences in MVPA in terms of country, gender and period of the week. Spanish adolescents were more active than French adolescents, boys were more active than girls and MVPA was higher on weekdays than at weekends. French girls showed the lowest level of PA. Only 35.9% of the whole sample met the guidelines for PA in both countries. Governments of relevant countries, especially France, should adopt PA promotion policies targeted at adolescents in order to enhance their compliance with PA guidelines.

The influence of parenting practices and parental presence on children's and adolescents' pre-competitive anxiety.

We examined parental influence on athletes' pre-competitive anxiety. The effect of parental presence during competition was studied as was the role of parenting practices. Data were collected from a sample of 341 athletes (201 basketball players and 140 tennis players) before an official competition. Analysis of variance indicated that the presence of both parents was associated with higher pre-competitive anxiety for all participants, except male tennis players. The absence of both parents did not result in less anxiety. A second analysis of variance revealed that females tennis players at provincial and national level perceived greater parental pressure than most other participants. Canonical correlation analysis showed a positive relationship between pre-competitive anxiety and parenting practices for tennis players, but not for basketball players. Directive behaviours and pressure were positively associated with pre-competitive anxiety for all tennis players, whereas praise and understanding was negatively related to anxiety for female tennis players only.

Girls' and boys' perceptions of physical education teachers' feedback: effects on performance and psychological responses.

In this study, we examined the perceptions of physical education (PE) teachers' feedback patterns with female and male high school students (n = 325). Eight physical education teachers (4 females and 4 males) were involved. We examined (a) whether teachers' feedback was perceived differently by boys and girls, and how the sex of the teacher influenced these perceptions, and (b) the effects of types of feedback (praise, no response-successful, encouragement, technical information, criticism, no response-unsuccessful, and teacher's invested time) on students' perceived competence, effort, enjoyment, and their PE performance. A multivariate analysis revealed an interaction between teacher and student gender on perceptions of teacher feedback. Hierarchical regression analyses highlighted that the perceived feedback significantly predicted students' perceptions of competence (DeltaR(2) = 0.088), effort (DeltaR(2) = 0.119), enjoyment (DeltaR(2) = 0.085), and their PE performance (DeltaR(2) = 0.039) after accounting for the gender of the students and teachers and the students' initial PE performance. The perceptions of praise and teachers' invested time were positively linked with the dependent variables, whereas encouragement and technical information and criticism were negatively linked. The findings are discussed in terms of teaching effectiveness and gender equity.
