The assessments included general information, the SAS, PSQI, and SF-36. Using SPSS 26.0 and PROCESS, we built an intermediary model to verify sleep quality as a mediator between anxiety and quality of life in patients with FD.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n SAS scores correlated positively with PSQI scores (\n r<\/jats:italic>\n \u00a0=\u00a00.543,\n P<\/jats:italic>\n \u00a0&lt;\u00a00.05) and inversely with SF-36 scores (\n r<\/jats:italic>\n \u00a0=\u00a0-0.775,\n P<\/jats:italic>\n \u00a0&lt;\u00a00.05). The PSQI score was negatively associated with the SF-36 score (\n r<\/jats:italic>\n \u00a0=\u00a0-0.591,\n P<\/jats:italic>\n \u00a0&lt;\u00a00.05). Anxiety had a significant total effect on quality of life (\n \u03b2<\/jats:italic>\n \u00a0=\u00a0-0.775,\n P<\/jats:italic>\n \u00a0&lt;\u00a00.001). After controlling for mediator variables, the direct effect of anxiety on quality of life remained significant (\n \u03b2<\/jats:italic>\n \u00a0=\u00a0-0.644,\n P<\/jats:italic>\n =&lt;0.001). The indirect effects of sleep quality [\n \u03b2<\/jats:italic>\n \u00a0=\u00a0-0.131, Boot 95% CI (-0.184, -0.082)] were significant, and 16.88% of the total effect was attributed to this mediating role.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Anxiety not only directly reduces the quality of life of patients with FD, but also indirectly affects their quality of life by worsening sleep quality. Sleep quality is an important mediating variable between anxiety and quality of life.<\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fpsyt.2026.1911650","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T05:32:18Z","timestamp":1789536738000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Analysis of the mediating effect of sleep quality between anxiety state and quality of life in patients with functional dyspepsia"],"prefix":"10.3389","volume":"17","author":[{"given":"Xiaoming","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Traditional Chinese Medicine, The First Affiliated Hospital of Changsha Medical University","place":["Changsha, Hunan, China"]},{"name":"Department of Gastroenterology, The First Affiliated Hospital of Changsha Medical University","place":["Changsha, Hunan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changjuan","family":"Lei","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Medicine, The First Affiliated Hospital of Changsha Medical University","place":["Changsha, Hunan, China"]},{"name":"Department of Gastroenterology, The First Affiliated Hospital of Changsha Medical University","place":["Changsha, Hunan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Xiao","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Medicine, The First Affiliated Hospital of Changsha Medical University","place":["Changsha, Hunan, China"]},{"name":"Department of Gastroenterology, The First Affiliated Hospital of Changsha Medical University","place":["Changsha, Hunan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heli","family":"He","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Medicine, The First Affiliated Hospital of Changsha Medical University","place":["Changsha, Hunan, China"]},{"name":"Department of Gastroenterology, The First Affiliated Hospital of Changsha Medical University","place":["Changsha, Hunan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"9","DOI":"10.1080\/17474124.2023.2162877","article-title":"The treatment of functional dyspepsia: present and future","volume":"17","author":"Lacy","year":"2023","journal-title":"Expert Rev Gastroenterol Hepatol"},{"key":"B2","doi-asserted-by":"publisher","first-page":"8","DOI":"10.1111\/apt.16072","article-title":"Systematic review and network meta\u2010analysis: efficacy of drugs for functional dyspepsia","volume":"53","author":"Ford","year":"2021","journal-title":"Alimentary Pharmacol Ther"},{"key":"B3","doi-asserted-by":"publisher","first-page":"4172","DOI":"10.1038\/s41598-024-54716-3","article-title":"Global prevalence of functional dyspepsia according to Rome criteria, 1990\u20132020: a systematic review and meta-analysis","volume":"14","author":"Lee","year":"2024","journal-title":"Sci Rep"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.3390\/nu15061544","article-title":"Food, dietary patterns, or is eating behavior to blame?
