This article draws upon data from a unique, 11-country study of young people's health behaviour, facilitated by the WHO Regional Office for Europe. Analyses of the data available on individual health behaviours cluster into two groups: (i) health enhancing behaviours; and (ii) health-compromising behaviours. The results were analysed to identify the strength and consistency of these lifestyles across countries. A relatively modest proportion of the variance of the original variables was explained by these two lifestyle factors, but a consistent pattern emerged between countries. This consistency indicates that the health-related lifestyles of young people may not vary greatly between the countries in the study, a finding which might be used as an encouragement for greater international cooperation in the development and use of health education materials for young people, which may be easily transferable between countries. The data also support a more integrated approach to health education based on the promotion of healthy lifestyles, rather than a focus on individual health behaviours.
