Peripheral neuropathy (PN) is regarded as one of the main microvascular complications of diabetes. But the association of NAFLD with PN is still unclear. We aimed to investigate the association between NAFLD and PN in US population by conducting a cross-sectional study. We enrolled 3029 participants aged 40\u201385\u00a0years from National Health and Nutrition Examination Survey (NHANES) 1999\u20132004. NAFLD was defined as a US Fatty Liver Index (FLI) score\u2009\u2265\u200930, and PN was defined as having one or more insensate areas on either foot. Participants were divided into two groups (with or without PN). We performed multivariate logistic regression models to evaluate the association between NAFLD and PN. Subgroup analyses were used to find out whether the association was stable in different stratified groups. Sensitivity analyses were conducted to assess the robustness of the results. All the analyses were weighted. Among the individuals, 524 (17.3%) had PN and 1250 (41.27%) had NAFLD. In the multivariate logistic regression models, NAFLD was associated with an increased risk of PN (OR 1.44 [1.03\u2009~\u20092.02]) after fully adjusting for covariates. In the subgroup analyses, NAFLD was significantly associated with PN in the age group (40\u201364\u00a0years), compared with those in the age group (65\u201385\u00a0years), (P for interaction: 0.004). The results of association of NAFLD with PN were stable in sensitivity analyses. In this cross-sectional study among US adults aged 40\u201385\u00a0years old, NAFLD was associated with an increased likelihood of prevalent PN.<\/jats:p>","DOI":"10.1038\/s41598-023-32115-4","type":"journal-article","created":{"date-parts":[[2023,4,4]],"date-time":"2023-04-04T11:12:19Z","timestamp":1680606739000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Association between nonalcoholic fatty liver disease and peripheral neuropathy in US population, a cross-sectional study"],"prefix":"10.1038","volume":"13","author":[{"given":"Xi","family":"Gu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dou","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Xuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Shen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei Qun","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,3,31]]},"reference":[{"key":"32115_CR1","doi-asserted-by":"publisher","first-page":"2809","DOI":"10.1016\/j.cgh.2021.12.002","volume":"20","author":"MH Le","year":"2022","unstructured":"Le, M.
