Health is markedly influenced by lifestyle health behaviours which require good practices or habits related to nutrition, exercise, the avoidance of smoking and alcohol, sleep and leisure activities, personal hygiene and dental hygiene. As a minimum, the adoption of healthy lifestyle habits requires health knowledge and a positive attitude to health, although these do not guarantee the performance of appropriate health behaviours because other factors may interfere. Children may be precluded from engaging in good lifestyle behaviours because of environmental factors such as their family circumstances. In addition, there are strong peer pressures that influence young people to adopt health risk behaviours such as smoking and drinking. Influential adults, such as parents and teachers, may also present role models that encourage children to try unhealthy lifestyle behaviours. Teaching children to lead a healthy lifestyle is an important task for present day Lithuania. Initial attempts at health education in the 1920's and 1930's were suppressed by the Soviet school and health care system. Although Soviet health care was formally based on principles of disease prevention, in reality, health promotion and health education were not supported. All resources were used to build hospitals and train doctors to treat disease. Despite the resources put into treatment, neither Lithuania nor any of the other republics of the former USSR compare favorably with the West on key health indicators including longevity or infant mortality.1 Unlike the former USSR, most countries in the West over the last few decades have devoted considerable attention to the promotion of healthy lifestyles among children and young people and have accumulated a rich experience about how to do so. For example, such projects can be mentioned as: Know Your Body in the USA and other countries,2,3 Westchester County Intervention Trial in New York, USA4, North Karelia Youth Project in Finland5, Oslo Youth Study in Norway6, Lifestyle Education Programme in Australia7, and Keep Your Body Healthy in Israel8.
