The Legacy and Sustainability plan for the Paris 2024 Olympic and Paralympic Games — 67 The Legacy and Sustainability plan for the Paris 2024 Olympic and Paralympic Games — 67 The results of the study are worrying: • 66% of 11- to 17-year-olds do not achieve the physical activity guideline of 60 minutes a day and do not meet the sedentary behaviour guideline of less than 2 hours a day. The health of almost two thirds of children and teenagers is therefore at risk. • 17% of this population are particularly at risk, as they have both the highest levels of physical inactivity (with less than 20 minutes of physical activity a day) and the highest levels of sedentary behaviour (over 4.5 hours of screen time a day). • Children’s age and sex, as well as the level of education of their parent or guardian are the main explanatory variables: there are higher levels of sedentary behaviour in young people whose parent or guardian has a low level of education or who come from a low-income household relative to the number of members, as well as in older teenagers (15- to 17-year-olds). Additionally, physical activity levels are lower in 11- to 14 year-old girls than boys their age. These levels justify strengthening comprehensive preventive actions that combat both sedentary behaviour and physical inactivity: • Actions aimed at older teenagers or those with the lowest social standing must be prioritised to combat sedentary behaviour. • When promoting physical activity, actions aimed at girls must be prioritised, for instance by raising awareness among their parents and educators. SEDENTARY LIFESTYLES POSE A SERIOUS PUBLIC HEALTH PROBLEM Organising the Games gives us a unique opportunity to make everybody aware of these alarming observations and help them to move more. Paris 2024 is committed to raising awareness among and convincing people – particularly young people and people who are not involved in sport – of the importance of becoming more physically active throughout the day. Paris 2024 has devised a strategy in collaboration with several experts (including doctors, sports instructors and teachers) and is adopting a transversal approach to ensure physical activity and sport are recognised as a public health tool and play a more prominent role in society, focusing on two main goals: 1. Make people want to move more by leading an inspiring discourse on the challenges of combating sedentary behaviour and promoting physical activity and sport 2. Create opportunities for people to move more through an engagement platform enabling everybody to play an active role at their level
