Consumption of junk food among adolescents has been recognized as a serious health problem in the world. Therefore, this study aims to assess the effectiveness of an educational intervention program (interactive lecture) based on the theory of planned behavior (TPB) for reducing junk food consumption among school adolescents in Birgunj Metropolitan City, Nepal. A structured questionnaire was deployed for collecting the data from four government schools. Pretest and Posttest group study design and simple random sampling techniques were used. A multiple linear regression model and a paired -test were used to assess the effectiveness of an educational intervention program. The theory of planned behavior indicates that behavioral intention of junk food consumption was different in pretest and posttest [5.43 ± 1.3 and 7.96 ± 0.3]. Furthermore, the average score of attitude toward junk food consumption was 11.9 ± 1.5 and 16.3 ± 1.6. Meanwhile, perceived behavior control (PBC) toward junk food was also different after intervention [2.42 ± 0.50 and 3.13 ± 0.58]. The interactive lecture method was proved an effective education program for changing the intentions of adolescent students and preventing them from consuming junk food which were statistically significant (<0.05). In addition, behavioral intention of junk food consumption, attitude toward junk food consumption, and perceived behavioral control toward junk food were statistically significant (<0.05). Therefore, study concluded that the intervention program has positive influence on the perceived behavior without control group of school-going adolescents.
青少年食用垃圾食品已被公认为全球一个严重的健康问题。因此，本研究旨在评估基于计划行为理论（TPB）的教育干预项目（互动讲座）对减少尼泊尔比尔根杰市公立学校青少年垃圾食品消费的有效性。通过结构化问卷从四所政府学校收集数据。采用前测和后测组研究设计以及简单随机抽样技术。使用多元线性回归模型和配对检验来评估教育干预项目的有效性。计划行为理论表明，垃圾食品消费的行为意向在前测和后测中有所不同[5.43±1.3和7.96±0.3]。此外，对垃圾食品消费态度的平均得分分别为11.9±1.5和16.3±1.6。同时，干预后对垃圾食品的感知行为控制（PBC）也有所不同[2.42±0.50和3.13±0.58]。互动讲座方法被证明是一个有效的教育项目，可改变青少年学生的意向并防止他们食用垃圾食品，具有统计学意义（<0.0）。此外，垃圾食品消费的行为意向、对垃圾食品消费的态度以及对垃圾食品的感知行为控制均具有统计学意义（<0.05）。因此，研究得出结论，该干预项目对未设对照组的在校青少年的感知行为有积极影响。
