To assess students’ nutritional junk food behaviors on interaction through their knowledge, attitudes, and amounting energy acquirements on junk food and the nutritional status of 429 upper secondary students in Thailand with the 20-item Questionnaire on Students’ Knowledge on Junk Food and Nutrition (QSKJFN), the 20-item Questionnaire on Nutritional Energy Quality on Junk Food (QNEQJF), and the 20-item Test of Nutritional Junk Food-Related Attitude (TNJFRA) on four scale in five options. These three research instruments are valid and reliable. Statistically significant with the Factor Loading Analysis was assessed for each item, Simple Correlation (r) was assessed the positional predictive variables, Multiple Correlation (R) was assessed the classification of the relative variables, Standardized Regression Weight Attitude (β) was assessed the abilities for predictive relationships of the variables, and the Determination Efficiency Predictive Value (R2) were analyzed between the variable of the QSKJFN and QNEQJF, the QSKJFN and TNJFRA, and the QSKJFN and TNJFRA are positive positions, to be able to predict the analyzing correlative variables, significantly (p<.05). The linear equations indicate that of y1 = 0.010x1 + 0.695 for the QSKJFN, y2 = 0.031x2 + 3.045 for QNEQJF, and y3 = 0.460x3 + 19.450 for the TNJFRA that interaction through students’ knowledge, attitudes, and amounting energy acquirements, increasingly. The R2 values indicate that 57%, 54%, and 41% of the variance in students’ attitudes to their knowledge of the nutrition was attributable to their perceptions of the nutritional junk food in their knowledge to their amounting energy acquirements of the nutrition was attributable to their perceptions of nutritional junk food, relatively.
