We have examined the correlations between dietary behaviors and, respectively, the factor of personal backgrounds, that of individual dietary choices, and that of dietary environments. We have also analyzed the predictive power of these three factors in the students’ dietary behaviors. The subjects are the junior high school students of a school in Taoyuan County. The data are collected by means of stratified-cluster random sampling , using self-designed structural questionnaires. 350 effective questionnaires are retrieved. The rate of retrieval was 94.1%. The findings of this study are as follows: 1.The subjects’ dietary behaviors were in general acceptable. They have better dietary behaviors in the three regular meals, and their dietary behaviors are also above average in terms of balanced diets, though on the whole their dietary behaviors do not attain the standards of the proposed balanced diets for adolescents by the Department of Health, Executive Yuan.On the aspect of individual dietary choices, the subjects have shown positive preferences. Their dietary self-efficacy was medium in scale, while their dietary knowledge was rather good.On the aspect of the subjects’ dietary environments, the availability of the vegetable, the fruit and the bread, cereal, rice and pasta groups is higher than the availability of the nuts and the milk, yogurt, and cheese groups.The subjects have enough sources of dietary information, mainly from the school and their family. Their family members are more important support than their classmates and friends in terms of dietary behaviors. 2.The findings have shown that the female students have better dietary techniques than male students, but male students’ diets are more balanced than female students’. In addition, Students of higher socio-economic backgrounds have more balanced diets than students of lower socio-economic backgrounds. 3.The subjects’ personal backgrounds, individual dietary choices, and dietary environments can effectively predict their dietary behaviors (adjust R2 =52.2%). Dietary preferences, dietary knowledge, dietary self-efficacy are three primary predictors of dietary behaviors. The more positive the students’ dietary preferences are, the more correct the students’ dietary knowledge is, and the higher the students’ dietary self-efficacy is, they will have better dietary behaviors. Among these three predictors, dietary self-efficacy is the most influential factor. The present study has made some suggestions for the future execution or improvement of junior high school’s nutrition education, so as to encourage the formation and the maintenance of healthy dietary behaviors of junior high school students.國中學生飲食行為飲食自我效能junior high school studentsdietary behaviordietary self-efficacy
