This study aimed to explore the association between the cMIND diet, anti-inflammatory dietary diversity (AIDD), and the risk of anxiety in older adults.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross-sectional analysis was conducted using data from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS). Anxiety symptoms were assessed using the Generalized Anxiety Disorder (GAD-7) scale, while adherence to the cMIND diet and AIDD was evaluated through a food frequency questionnaire. Univariable and multivariable logistic regression analyses were performed to examine associations between dietary patterns and anxiety risk, with odds ratios (ORs) and 95% confidence intervals (CIs) reported. Random forest analysis was used to identify key factors influencing anxiety, and sensitivity analyses were conducted to test the robustness of the results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 13,815 participants aged 65 and older were included, with 1,550 (11.2%) identified with anxiety. Multivariable logistic models indicated that adherence to the cMIND diet or higher AIDD was associated with a 16\u201326% reduced risk of anxiety, with the adjusted ORs (95% CIs) for the cMIND diet ranging from 0.75 (0.64\u20130.87) to 0.75 (0.61\u20130.91), and for AIDD from 0.74 (0.62\u20130.88) to 0.84 (0.73\u20130.96). Sensitivity analyses confirmed the stability of these findings. Depression and sleep quality were identified as the most important factors contributing to anxiety, while diet was one of the few modifiable factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study provides evidence supporting the association between diet and anxiety in older adults, highlighting the potential of promoting healthy dietary patterns and targeted nutritional interventions as effective strategies for improving mental health in the aging population.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnut.2025.1548072","type":"journal-article","created":{"date-parts":[[2025,3,3]],"date-time":"2025-03-03T05:16:41Z","timestamp":1740979001000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Adherence to the cMIND and AIDD diets and their associations with anxiety in older adults in China"],"prefix":"10.3389","volume":"12","author":[{"given":"Yana","family":"Qi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyu","family":"Xue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ningsu","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Gong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongyu","family":"Mu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengnan","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youping","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Shi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiajie","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,3,3]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"101174","DOI":"10.1016\/j.arr.2020.101174","article-title":"A research agenda for ageing in China in the 21st century (2nd edition): focusing on basic and translational research, long-term care, policy and social networks","volume":"64","author":"Fang","year":"2020","journal-title":"Ageing Res Rev"},{"key":"ref2","year":"2022"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"211","DOI":"10.1016\/S2215-0366(18)30511-X","article-title":"Prevalence of mental disorders in China: a cross-sectional epidemiological study","volume":"6","author":"Huang","year":"2019","journal-title":"Lancet Psychiatry"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"e0156937","DOI":"10.1371\/journal.pone.0156937","article-title":"Factors influencing the prevalence of mental health problems among Malay elderly residing in a rural community: a cross-sectional study","volume":"11","author":"Abdul Manaf","year":"2016","journal-title":"PLoS One"},{"key":"ref5","doi-asserted-by":"crossref","DOI":"10.1007\/978-981-32-9705-0_28","article-title":"Anxiety disorders in the elderly","volume-title":"Anxiety disorders.
