This study aimed to determine the potential association of various nutritional indices with AD at different stages.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Subjects, including individuals with normal cognition (NC) and patients diagnosed with AD, were consecutively enrolled in this cross-sectional study. Demographics, body composition, dietary patterns, nutritional assessment scales and nutrition-related laboratory variables were collected. Binary logistics regression analyses and receiver operating characteristic (ROC) curves were used to indicate the association between nutrition-related variables and AD at different stages.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Totals of 266 subjects, including 73 subjects with NC, 72 subjects with mild cognitive impairment due to AD (AD-MCI) and 121 subjects with dementia due to AD (AD-D) were included. There was no significant difference in dietary patterns, including Mediterranean diet and Mediterranean-DASH diet intervention for neurodegenerative delay (MIND) diet between the three groups. Lower BMI value, smaller hip and calf circumferences, lower Mini Nutritional Assessment (MNA) and Geriatric Nutritional Risk Index (GNRI) scores, and lower levels of total protein, albumin, globulin, and apolipoprotein A1 were associated with AD (all <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.05). Total protein and albumin levels had the greatest ability to distinguish AD from non-AD (AUC 0.80, 95% CI 0.74\u20130.84, <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.001), increased by combining calf circumference, MNA score and albumin level (AUC 0.83, 95% CI 0.77\u20130.88, <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.001).
