Articles Published in Korean Journal of Family Medicine: Impact of COVID-19 on Study Trends.

Background: The Korean Journal of Family Medicine (KJFM), which is an official journal of the Korean Academy of Family Medicine, is an English-text medical journal published since 2009. Although nearly 15 years have passed since the journal was launched, to the best of our knowledge, no study has reviewed articles published in the KJFM. Accordingly, we analyzed articles published in the KJFM for the first time.

Methods: Articles published in the KJFM between January 2018 and November 2023 were categorized according to article type. Information about author affiliations, study subjects, research methods, and modes of data collection was then scrutinized. Moreover, we compared the frequencies of subjects, research methods and modes of data collection before, during, and after the coronavirus disease 2019 pandemic.

Results: Original article was the most common article type. Approximately 52% of the articles were published by authors affiliated with departments other than family medicine, and 40% were published by family medicine. Approximately 60% and 38% of the articles were published by Korean authors and authors of international affiliations, respectively. Throughout the pandemic periods, research subjects focusing on "diseases & symptoms" have diminished, while "principles of family medicine" have progressively increased. Additionally, the use of cross-sectional study methods has declined. In terms of data collection, the use of "big data," "medical records," and "questionnaires" has decreased, whereas the use of "study results" has increased.

Conclusion: KJFM is journal with wide and international participation covering various research subjects and study methods. We believe that our study provides valuable data for the future direction and development of the KJFM.
