Food Knowledge, Habits, Practices, and Addiction Among Adolescents: A Cross-Sectional Investigation

Background: Changing lifestyles and food habits have an impact on both nutrient requirements and intake among adolescents. The aim of this study is to assess the level of knowledge, habits, practices, and the presence of food addiction among adolescents residing in Damanhur City. Methods: A descriptive correlational study design is employed to collect data from 363 adolescents selected conveniently from two youth centers in Damanhur, Egypt. Four tools are used: a demographic questionnaire, the Adolescent Food Habits Checklist (AFHC), the General Nutritional Knowledge Assessment Questionnaire (GNKQ), and the Yale Food Addiction Scale version 2.0 (YFAS 2.0). Results: The age of the participating adolescents ranges from 10 to 19 years. More than half of the participants (51.8%) reported choosing low-fat foods. Additionally, around one-third of the adolescents (34.7%) meet the diagnostic criteria for food addiction. However, there is no statistically significant association found between food addiction and adolescents' eating habits and practices. Conclusion and recommendations: Most of the studied adolescents exhibit unhealthy eating practices. Food addiction is identified as a significant health concern among this population. Therefore, it is highly recommended to provide nutritional education for adolescents and their families and implement school-based strategies to promote healthy eating habits.
