Abstract: (110 Views)
Introduction: Inappropriate dietary habits, particularly the growing tendency to consume fast food, pose significant health challenges in modern society, especially among adolescents. This study aimed to evaluate the effectiveness of a health education program based on the Theory of Planned Behavior (TPB) in reducing fast food consumption among female high school students.
Methods: In this study, the sample size was determined to be 38 individuals per group (95% (CI) and, 90% power), but 50 were included to increase accuracy. Thus, 100 students from District 4 of Tehran were divided into control and intervention groups using cluster random sampling. Data were collected via a valid questionnaire assessed by five health education professors, covering demographic information, knowledge, and TPB constructs. The intervention group participated in three 50-minute educational sessions, including lectures, Q&A discussions, and the distribution of brochures and books. The data were analyzed using SPSS-22, employing statistical tests such as Kolmogorov-Smirnov, Mann-Whitney U, Chi-square and independent t-tests.
Findings: Following the educational intervention, the mean scores for attitude (p=0.002), subjective norms (p=0.005), and perceived behavioral control (p=0.005) were significantly higher in the intervention group compared to the control group. However, no significant changes were observed in knowledge (p=0.936), behavioral intention (p=0.393), and behavior (p=0.721) related to reducing fast food consumption.
Conclusion: The educational program based on the TPB, positively influenced attitudes, subjective norms, and perceived behavioral control. However, further research is needed to explore strategies for translating these improvements into measurable changes in knowledge, behavioral intention, and actual fast food consumption behavior.
