News articles published between 2006 and 2022 related to mifepristone were collected using web scraping from representative news platforms in both countries. The collected data underwent preprocessing, followed by text analysis using the bag-of-words model. Topic modeling was conducted through Latent Dirichlet Allocation, and sentiment analysis involved using the lexicon-based methods specific to Korean and English texts. Analysis of 7,938 Korean and 650 United States articles revealed distinct patterns in media discourse on mifepristone and medical abortion. The United States coverage was polarized, encompassing clinical, legal, and access-related debates, whereas Korean articles prioritized access barriers, safety concerns, and the urgency for domestic approval, reflecting predominantly negative sentiments related to cultural stigma. This study highlights differences in the media portrayals and public perceptions of mifepristone between South Korea and the United States, underscoring the influence of regulatory contexts, public concerns and cultural attitudes on medical abortion discourse.<\/jats:p>","DOI":"10.1371\/journal.pone.0342848","type":"journal-article","created":{"date-parts":[[2026,3,6]],"date-time":"2026-03-06T18:22:18Z","timestamp":1772821338000},"page":"e0342848","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative analysis of social issues toward medical abortion using mifepristone in South Korea and the United States: Topic modeling and sentiment analysis"],"prefix":"10.1371","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9178-8785","authenticated-orcid":true,"given":"Minoh","family":"Ko","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong-Young","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung Mi","family":"Oh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3687-4052","authenticated-orcid":true,"given":"Yun-Kyoung","family":"Song","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2026,3,6]]},"reference":[{"issue":"3","key":"pone.0342848.ref001","doi-asserted-by":"crossref","first-page":"368","DOI":"10.1017\/S0963180122000834","article-title":"A Balance of rights: the Italian way to the abortion controversy","volume":"32","author":"M Reichlin","year":"2023","journal-title":"Camb Q Healthc Ethics"},{"issue":"4","key":"pone.0342848.ref002","doi-asserted-by":"crossref","first-page":"185","DOI":"10.1080\/ejc.6.4.185.191","article-title":"Medical abortion as an alternative to vacuum aspiration: first experiences with the \u201cabortion pill\u201d in The Netherlands","volume":"6","author":"J Rademakers","year":"2001","journal-title":"Eur J Contracept Reprod Health Care"},{"issue":"3","key":"pone.0342848.ref003","doi-asserted-by":"crossref","first-page":"154","DOI":"10.2307\/3097714","article-title":"Mifepristone for early medical abortion: experiences in France, Great Britain and Sweden","volume":"34","author":"RK Jones","year":"2002","journal-title":"Perspect Sex Reprod Health"},{"issue":"2","key":"pone.0342848.ref004","doi-asserted-by":"crossref","first-page":"109","DOI":"10.1080\/ejc.8.2.109.121","article-title":"Changing attitudes towards abortion in Europe","volume":"8","author":"E Arisi","year":"2003","journal-title":"Eur J Contracept Reprod Health Care"},{"key":"pone.0342848.ref005","volume-title":"WHO Model List of Essential Medicines \u2013 21st List 2019 [Internet]","author":"World Health Organization","year":"2019"},{"key":"pone.0342848.ref006","volume-title":"Mifepristone-Misoprostol.
