However, no study has explored its prevalence in adults under 30 years of age. Therefore, we performed a cross-sectional study to investigate the prevalence of NAFLD in Korean men in their early 20s.Methods: We collected data of 596,359 Korean soldiers who participated in a health examination between January 2015 and July 2021. A total of 571,872 individuals were analyzed after excluding those with missing data and hepatitis B antigen positivity. Hepatic steatosis was determined using the hepatic steatosis index (HSI). Participants with HSI &gt;36 were considered to have NAFLD.Results: All participants were men, and the mean age was 20.9\u00b11.3 years. Of the 571,872 participants screened, 77,020 (13.47%) were classified as having NAFLD. The prevalence of NAFLD consistently increased from 2015 to 2021 (10.66% vs. 16.44%, P&lt;0.001). Increases from 2015 to 2021 were also noted in the prevalence of hypercholesterolemia, hyperglycemia, and hypertension (P&lt;0.001 for all). The mean body mass index also increased from 23.3\u00b13.0 kg\/m2 to 23.9\u00b13.1 kg\/m2 between 2015 and 2021 (P&lt;0.001).Conclusions: The prevalence of NAFLD and of other metabolic dysfunctions in Korean men in their early 20s increased from 2015 to 2021.<\/jats:p>","DOI":"10.3350\/cmh.2021.0371","type":"journal-article","created":{"date-parts":[[2022,1,13]],"date-time":"2022-01-13T07:46:36Z","timestamp":1642059996000},"page":"196-206","update-policy":"https:\/\/doi.org\/10.3350\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Prevalence
