Insufficient physical activity and sedentary behaviors (SB) are major risk factors for non-communicable diseases. Monitoring the prevalence of physical activity (PA) and SB is essential to meet the health needs of the population. This article presents the prevalence of PA and SB in the French population and their evolution during the last decade. Data come from two cross-sectional surveys, representative of the population in France, the "Etude Nationale Nutrition Santé" 2006-2007 and the Esteban study 2014-2016, and were collected through the International Physical Activity Questionnaire and the Recent Physical Activity Questionnaire for adults, the Youth Risk Behavior Survey and specific questionnaire for children. In 2014-2016, 71% of men and 53% of women met the PA recommendations (5 or more days per week with a moderate-intensity physical activity of at least 30 min per day). Since 2006-2007, PA has decreased for women, but increased for men; 80% of adults reported a daily leisure screen time of at least three hours in 2014-2016, in strong growth since 2006-2007. Among children, only 51% of boys and 33% of girls were meeting the PA recommendations (at least 60 min of moderate- to vigorous-intensity physical activity daily). PA decreased significantly after the age of 10. Three-quarters of children spent two hours or more in front of a screen every day. These results show a lack of PA, in particular among women and girls, a high prevalence of SB in the French population, and a deterioration of these behaviours between 2006 and 2016.
