Youth health has been at the center of public debate for several years. A “Youth Health” plan focused on 16- to 25-year-olds was presented by the Ministry of Health, Youth, and Sports in February 2008, followed by a series of specific measures set forth in the Hospitals, Patients, Health, and Territories in July 2009. President François Hollande also made it one of the priorities of his term in office in terms of actions in the health and social sectors. This political focus on young people likely stems more from the medicalization of social issues (Fassin, 1998) than from a health situation that does not appear particularly alarming (Sommelet, 2007; Loncle, 2007). Such attention from public authorities inevitably leads to a constantly evolving need for knowledge, not only regarding health status but also—especially when it comes to young people—regarding health behaviors.[article excerpt]
