Track 4: From nutrition, exercise and psychology to lifestyle

An understanding of the determinants of physical activity is needed when planning health promotion programs. Several determinants from an individual level have been identified. The most often sited individual determinants (or barriers) are lack of motivation and lack of time. The latter is interesting, since one may also say that a lack of time is not real, but in fact also an expression of lack of motivation. Individuals may also lack company, self-efficacy or money. However, several studies show that both the built (physical) environment and social environment are strong predictors of physical activity, at least on group level. The physical environment can be related to distances, attractiveness, street connectivity, weather and safety. In the international ISCOLE-study, environmental influence on both physical activity and diet in 10-y-old children are studied by focusing on home, home neighborhood and school in 12 countries in five continents. The environment is characterized by both questionnaires and a new instrument called “school audit” (observational tool, completed by investigators). This study will bring new insight into environmental determinants of physical activity in very different countries.
