Interpretation and related factors of healthy eating among young people in Japan

OBJECTIVE: The purpose of this study is to interpret and determine factors related to "healthy eating" among young people in Japan. The findings would be useful in improving the consciousness among young people regarding healthy food, eventually leading to the prevention of lifestyle-related diseases. METHOD: We conducted a questionnaire survey among young people in Saga and Fukuoka prefecture (n = 482) from October through November, 2004. The data were analyzed using chi-square test, one-way ANOVA, factor analysis and multiple regression analysis. RESULTS: (1) As for the interpretation of "healthy food", 2 factors ("eating style and habits" and "food and nutrition") were extracted in the factor analysis. This was in line with the interpretation among adults. (2) The scores of "eating style and habits" and "food and nutrition" increased with the age of the subjects, and a significant difference in grade was observed (p = 0.00). (3) Sex and physical exercise were related to "eating style and habits" score (p = 0.00), whereas age and sex were related to "food and nutrition" score (p = 0.00). CONCLUSION: The interpretation of "healthy food" among young people was consistent with that among adults. However, it is implied that the traditional view of "healthy food" has begun to change among young people. The necessity of proper eating habits at home and food education out side is implied.
