In this study, the theory of planned behavior (TPB) was applied to predict the intention to avoid daily intake of sugared snacks and drinks among Tanzanian adolescents. The empirical data stem from a self-administered questionnaire survey of secondary school students in Kibaha district (N=532) conducted in July 1997. A total of 312 pupils (mean age, 16.2 yr) participated. The main procedure used in the analysis was hierarchical forced-entry multiple regression analysis. In the final model, four variables explained 54% of the variance in behavioral intention which was primarily governed by perceived behavioral control and subjective norms, while attitudes and perceived risk of having tooth decay had less impact. The applicability of the TPB to the study of food choices among adolescents living in a non-occidental setting was confirmed. The results are discussed in the light of their implication for health education.
