O7-6 Global Matrix 3.0 Physical Activity Report Card for Children and Youth: A comparison across Europe

Abstract Background The Global Matrix of report card grades on physical activity serves as a public health awareness tool by summarising the status of child and youth physical activity prevalence and action. Since schools and the wider community and environment are critical influences on the physical activity levels of children and youth, this research sought to examine the factors considered when assigning these grades across included European countries. Specifically, we sought to: (1) provide a detailed examination of the evidence informing these indicators across participating European Global Matrix 3.0 countries; (2) explore the comparability of the grades for these two indicators across Europe; (3) detail any limitations or issues with the methods used to assign grades; and (4) provide suggestions on how future grading of the indicators could be improved. Methods Key documents relating to the European countries involved in the 2018 Global Matrix 3.0 were collated. This inlcuded the long and short forms of the report card for each country as well as the scientific paper. A template was developed and used to capture information on: the grade assigned for each indicator; details of the data used to assign the grade, the source of the data; indication of the quality of the data and any reported challenges or issues in assigning the grade for both the ‘School' and ‘Community and Environment' indicators. Results Seventeen of the 20 European Report Card countries (85%) had a grade for schools, and 15 countries (75%) had a grade for community and environment. All countries considered between one and five factors when assigning the grade for these indicators. There were wide disparities in the number and sources of evidence used to assign the grades for both indicators, limiting the comparability of the evidence between different countries. Conclusions To enable comparability, the authors recommend moving towards an agreed standardised set of metrics for grading each indicator. Furthermore, it would be useful to develop and share common tools, methods and instruments in order to collect data in a uniform way across countries. Such action will ultimately make the Global Matrix a more robust tool for future use.


Background
Insufficient physical activity (PA) is an important risk factor for overweight and obesity among adolescents, both causes of cardiovascular diseases.Sport is the largest contributor to achieving the World Health Organization (WHO) PA levels guidelines.However, few studies have investigated temporal trends in weekly sport participation in relation to adolescents' weight status.The main objective of this study was to compare sport participation to weight status and investigate their relationship over time.Methods Two data collections were conducted during spring 2015 (n = 1019) and 2019 (n = 1112) in 30 French high schools.Adolescents reported their age, sex, height, weight, parents' socioeconomic status (SES) and hours of sport per week.Body mass index was calculated and classified into three categories (normal weight, overweight, obese) according to the 12.3%) and those not playing sport (34.2% to 35.9%).These changes varied according to adolescents' SES.In 2019, low-SES adolescents were 1.5 times less likely to play sport (95% CI:1.17-1.99)while no change was observed among high-SES adolescents.Finally, 7+ adolescents were no more likely to be overweight or obese in 2019 compared to 2015.Contrarily, NS and 7-adolescents were 1.7 and 1.8 times more likely respectively to be overweight or obese in 2019 compared to 2015.

Conclusion
These results confirm the adequacy of WHO PA recommenda-
