Disadvantage in school age affects health during the remaining part of
life. Health promotion might alleviate this situation. It is reasonab
le to focus on mental health, since this is the leading cause of disab
ility adjusted life years lost in this age group and to focus on the s
chool, since this is the most important setting. Go-operation between
the public health and the educational sector is rational, yet complica
ted by different perspectives on knowledge and technology used in thes
e two sectors. It is, however, possible to carry through a dialogue. T
hen, the public health representatives have to clarify current scienti
fic knowledge on health promotive characteristics of the school. Such
characteristics are, enhanced health control at school, aged mixed abi
lity grouping, class sizes of 15-20 students, a task oriented school c
ulture and employment of skills training programmes, e.g, for tobacco
deterrence.
