Health and education are linked and children cannot make the most of educational opportunities if their health is impaired (Smith & Sherwin, 2009). Health promotion is the process of enabling people to increase control over, and to improve their health (WHO, 1998a). Schools intend to help pupils acquire the knowledge and develop the skills they need to participate fully in adult life (Burgher, Barnekow Rasmussen & Rivett, 1999). School is regarded as constituting a very important arena for health education among children and young people (Hagquist & Starrin, 1997) and furthermore, it is seen as an important context for health promotion, mainly because it reaches a large proportion of the population for many years (Naidoo & Wills, 2000). One of the aims of the "wholeschool" approach should be the support of learning and the promotion of health and well-being.
