This study aimed to examine the associations of kidney function, assessed by estimated glomerular filtration rate (eGFR), and nutritional factors with homocysteine levels in community\u2010dwelling older adults. This cross\u2010sectional study enrolled participants aged \u2265\u200965\u2009years. Demographic characteristics were collected using questionnaires. Biochemical parameters, including homocysteine, folic acid, vitamin B\n                    <jats:sub>12<\/jats:sub>\n                    , and metabolic disorder indicators, were measured, and eGFR was calculated and categorized into three groups. Homocysteine concentrations were significantly higher in the low and moderate eGFR groups compared with the high eGFR group (median: 16.9 vs. 11.9 vs. 9.3\u2009\u03bcM,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.01). Regression analyses indicated that each 1\u2010unit decrease in eGFR was associated with higher homocysteine (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u2009=\u2009\u22120.13,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.01).
