Cerebrospinal fluid (CSF) biomarkers and PET imaging were used to assess amyloid-\u03b2 (A) and Tau (T) tangles load, classifying participants into AT profiles based on the results. The association of BW and SUA with AT profiles was evaluated using multivariable logistic regression, and their relationship with cognitive function (Mini-Mental State Examination (MMSE) scores) were analyzed using multivariable linear regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Lower BW levels significantly influenced the presence of A\u03b2 positive state (A+) (p\u2009=\u20090.007), while SUA levels did not (p\u2009=\u20090.263). Higher dementia proportion (p\u2009=\u20090.021), lighter BW (p\u2009=\u20090.019), and lower mean arterial pressure (MAP) levels (p\u2009=\u20090.025) were associated with AD pathological progress (A-T-\u2192A+T-\u2192A+T+), but SUA was not observed statistically significant. Among all participants regardless of A\u03b2 state, high education levels (p\u2009&lt;\u20090.001), high BW (p\u2009=\u20090.010), and high SUA (p=0.036) were associated with high MMSE scores, and
