This study conducted a social network analysis (Semantic Network Analysis) to identify research trends (1990∼2018) related to "the dietary life of adolescents". Twenty-five journals were selected based on the classification of the Korea Research Foundation, from which 681 articles were collected using the author’s keywords. Eventually 1123 key words were extracted, refined, and used for this study. In order to examine the changes in research trends on "the dietary life of adolescents", the period was categorized into the following three parts: the first period (1990∼1999); the second period (2000∼2009); and the third period (2010∼2018). Then, we measured network centrality and keyword frequency, and we also visualized the semantic network using the "arules" and the "sna" package of the R program. The results were as follows: Keywords, such as "nutrition, preference, dietary habits, and habits" were listed among the top 20 keywords, which showed the major research topics throughout the period (1991∼2018). According to the result of key words centrality, the main topics of each period were as follows: Period 1 included "food intake and obesity of adolescents" period 2 included "nutrition and food intake", "school meal service", "nutrition education"," body image of adolescent", "weight control", and "dietary habits" and period 3 included "intake", "school meal", "dietary control" and "sugar consumption", "green dietary life", and "dietary control and emotion". Our results show that the research contents on the dietary life of adolescents were expanded, specified, and progressed with time and social changes. Hopefully, this study will be a small reference to predict long-term trends on the dietary life of adolescents.
