Abstract

The purpose of this study was to examine the research trend of nutrition for the recent 12 years from 1996 to 2007 by analyzing 734 articles published in the Korean Journal of Community Nutrition. The majority of the articles (61.4%) were classified as survey types in terms of data collection methods. Most of the subjects used in the articles were adults (28.8%), and the subject whose research has been increased at the highest rate was "patients". The most frequent keywords in the title of articles were "nutrient intake" (231times), "food service" (92times), "dietary habits" (69times), and "obesity" (69times). The keywords that have appeared more frequently with the years were "osteoporosis" (450.0%), "menopause" (350.0%) and "dietary attitudes" (208.3%). As for research interests, "nutrient intake" was dominant in the early stage of research while "disease", "dietary habits", "dietary attitudes" and "nutrition education" have increased in recent years. Some of the most common methods of nutrition assessment were "dietary intake" (41.2%), "anthropometric" (34.0%) and "biochemical test" (14.7%). The most common methods of dietary intake were "24-hours recall" (28.6%) and "dietary habits" (23.3%). The results of this study showed some biases in data collection methods, gender of the subjects, and study areas. Moreover, inconsistent terminologies, questionnaire contents, and measures were used for the researches on dietary behaviors, dietary habits, dietary attitudes, which made it difficult to compare their results for each research. Therefore, standardized research methods and terminologies need to be developed regarding dietary practices.

Keywords: research trend, nutrition, analysis of articles, Korean journal of community nutrition
