The present chapter discusses trends in public health among 16-24-year-olds-young people who are poised precariously between childhood and adulthood. The group includes upper-secondary school pupils and young people who have gone on to higher education or work. Along with the rest of the population, young people have benefited from the development of postwar health and welfare policies and programs. Since the 1990s, however, the health of young people-particularly their mental health-has not shown the same general improvement as that of other age groups. Since health status surveys began at the end of the 1980s, the proportion of young people aged 16-24 who suffer from anxiousness, nervousness and anxiety (angst) has increased. In 1988-1989, 9 per cent of women and 4 per cent of men reported experiencing feelings of anxiousness, nervousness or anxiety. In 2004-2005, the percentage had risen to 30 per cent among women and 14 per cent among men. This increase not only subsumes self-reported complaints such as anxiousness, nervousness and anxiety; it has also become more common for young people to be hospitalised with depression and states of anxiety. The percentage of 20-24-year-old men and women who were hospitalised with depression more than doubled between 1990 and 2010, and in the 16-19 age group, hospitalisation have become eight times as frequent among women and four times among men. Hospitalisation as a result of suicide attempts or other self-destructive behaviour rose
