To investigate the clinical implications of this relationship, we sought to identify the difference in the serum levels of vitamins A and E according to NAFLD status using data from the seventh Korea National Health and Nutrition Examination Survey. In this cross-sectional study of the Korean population, NAFLD and its severity were defined using prediction models. Differences in the prevalence and severity of NAFLD were analyzed according to serum retinol (vitamin A) and alpha (\u03b1)-tocopherol (vitamin E) levels. Serum levels of retinol and \u03b1-tocopherol were positively correlated with the prevalence of NAFLD. In most prediction models of the NAFLD subjects, serum retinol deficiency was significantly correlated with advanced fibrosis, while serum \u03b1-tocopherol levels did not differ between individuals with or without advanced fibrosis. Similar trends were also noted with cholesterol-adjusted levels of \u03b1-tocopherol. In summary, while circulating concentrations of retinol and \u03b1-tocopherol were positively associated with the presence of NAFLD, advanced liver fibrosis was only correlated with serum retinol levels. Our findings could provide insight into NAFLD patient care at a micronutrient level.<\/jats:p>","DOI":"10.3390\/nu13051720","type":"journal-article","created":{"date-parts":[[2021,5,19]],"date-time":"2021-05-19T21:49:21Z","timestamp":1621460961000},"page":"1720","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Dynamics of Serum Retinol and Alpha-Tocopherol Levels According to Non-Alcoholic Fatty Liver Disease Status"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0847-6030","authenticated-orcid":false,"given":"Dongsub","family":"Jeon","sequence":"first","affiliation":[{"name":"Liver Center, Asan Medical Center, Department of Gastroenterology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0047-3102","authenticated-orcid":false,"given":"Minkook","family":"Son","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science and Engineering, Gwangju Institute of Science and Technology, Gwangju 61005, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juhyun","family":"Shim","sequence":"additional","affiliation":[{"name":"Liver Center, Asan Medical Center, Department of Gastroenterology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1002\/hep.28431","article-title":"Global epidemiology of nonalcoholic fatty liver disease-Meta-analytic assessment of prevalence, incidence, and outcomes","volume":"64","author":"Younossi","year":"2016","journal-title":"Hepatology"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"European Association for the Study of the Liver, European Association for the Study of Diabetes, and European Association for the Study of Obesity (2016).
