Knowledge Regarding the Harmful Impact of Junk Food Among Adolescents: A Descriptive Study from Dehradun, India

Background: Increased consumption of junk food among adolescents is a growing public health concern, contributing to obesity and lifestyle-related diseases. Objective: To assess the level of knowledge regarding the harmful impact of junk food among adolescents in selected senior secondary schools of Dehradun, Uttarakhand. Methods: A quantitative descriptive cross-sectional study was conducted among 60 adolescents selected using simple random sampling. Data were collected using a validated self-structured knowledge questionnaire and analyzed using descriptive and inferential statistics. Results: The majority of participants (95%) demonstrated an average level of knowledge, while only 5% showed good knowledge. No statistically significant association was found between knowledge level and selected socio-demographic variables (p > 0.05). Conclusion: Although basic awareness regarding junk food hazards exists among adolescents, in-depth understanding remains insufficient. Structured school-based nutrition education programs are essential to bridge knowledge gaps and promote healthy dietary practices.
