However, few studies have examined biochemical correlates of psychological health in this population. This study investigated the associations of serum brain-derived neurotrophic factors (BDNF) and adiponectin with anxiety, depression, and stress among deaf adults. A cross-sectional study was conducted among 204 deaf adults aged 18\u201345\u202fyears. Anxiety and depression were assessed using the DASS-21 questionnaire. Body composition analyses were performed using bioelectrical impedance analysis, and serum BDNF and adiponectin levels were measured. Serum BDNF concentrations were inversely associated with anxiety (\n                    <jats:italic>r<\/jats:italic>\n                    \u202f=\u202f\u22120.632,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001), depression (\n                    <jats:italic>r<\/jats:italic>\n                    \u202f=\u202f\u22120.732,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001), and stress (\n                    <jats:italic>r<\/jats:italic>\n                    \u202f=\u202f\u22120.795,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001).

In multiple linear regression analyses adjusted for age, sex, and body mass index (BMI), BDNF remained an independent inverse predictor of anxiety (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u202f=\u202f\u22120.48,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001), depression (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u202f=\u202f\u22120.55,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001), and stress (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u202f=\u202f\u22120.62,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001).

Lower serum BDNF and adiponectin concentrations were independently associated with higher levels of anxiety, depression, and stress among deaf adults. These findings suggest that BDNF, and to a lesser extent adiponectin, may represent potential biomarkers of psychological distress in this population.\n                  <\/jats:p>","DOI":"10.3389\/fnbeh.2026.1955159","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T05:52:18Z","timestamp":1791352338000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Association of serum brain-derived neurotrophic factor and adiponectin with anxiety, depression, and stress in deaf adults: a cross-sectional study"],"prefix":"10.3389","volume":"20","author":[{"given":"Rand","family":"Alsharq","sequence":"first","affiliation":[{"name":"Department of Clinical Nutrition and Dietetics, Faculty of Allied Medical Sciences, Applied Science Private University","place":["Amman, Jordan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anfal","family":"AL-Dalaeen","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition and Dietetics, Faculty of Allied Medical Sciences, Applied Science Private University","place":["Amman, Jordan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eman","family":"Saleh","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition and Dietetics, Faculty of Allied Medical Sciences, Applied Science Private University","place":["Amman, Jordan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nour","family":"Batarseh","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition and Dietetics, Faculty of Allied Medical Sciences, Applied Science Private University","place":["Amman, Jordan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abeer Ahmad","family":"Bahathig","sequence":"additional","affiliation":[{"name":"Department of Community Health, College of Applied Medical Sciences, Northern Border University","place":["Arar, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,10,7]]},"reference":[{"key":"ref1","first-page":"6325","article-title":"Author correction: developing brain asymmetry shapes cognitive and psychiatric outcomes in adolescence","volume":"16","author":"Alsharq","year":"2026","journal-title":"Nat.
