The Legacy and Sustainability plan for the Paris 2024 Olympic and Paralympic Games — 66 SEDENTARY LIFESTYLES POSE A SERIOUS PUBLIC HEALTH PROBLEM Nowadays, we tend to lead sedentary lifestyles characterised by physical inactivity. However, scientific research has proven that this has serious consequences for our health. The figures are shocking: almost one in two people in France is obese (17%) or overweight (31%). The Covid-19 pandemic is a health emergency that strengthens this observation: even moderate- intensity physical activity and sport boost the immune system and play an essential role in preventing and treating many illnesses and maintaining good overall physical and mental health. Moving a little bit every day reduces the risk of premature death by 30%, cuts the risk of depression by 30% and lowers the risk of many types of cancer. SPORT TO IMPROVE HEALTH, EDUCATION AND CIVIC ENGAGEMENT SPORT TO IMPROVE HEALTH The French Agency for Food, Environmental and Occupational Health & Safety (Anses) shares its view on assessing risks related to levels of physical activity and sedentary behaviour among children and teenagers The Anses study published in September 2020 aims to estimate the proportion of children and teenagers whose sedentary behaviour or low levels of physical activity could present risks to their health. It recommends that 6- to 17-year-olds have no more than two hours of leisure screen time a day and engage in at least 60 minutes of moderate- to vigorous-intensity physical activity a day. SCREEN TIME NO MORE THAN 2 hours a day PHYSICAL ACTIVITY AT LEAST 60 minutes a day ANSES GUIDELINES FOR 11- TO 17-YEAR-OLDS: 11- TO 17- YEAR-OLDS 66% do not achieve the Anses guidelines, putting their health at risk 17% are particularly at risk (less than 20 minutes of physical activity, coupled with over 4.5 hours of screen time a day)
