Cognitive function was assessed using the Chinese version of the Mini\u2010Mental State Examination (MMSE). Kidney function was evaluated by eGFR (CKD\u2010EPI equation) and the urinary albumin\u2010to\u2010creatinine ratio (ACR), classified by KDIGO categories and quartiles.

Prospectively, over a 3\u2010year follow\u2010up, 143 of 1195 cognitively normal participants developed CI.

Similarly, elevated ACR (categories A2 and A3) was associated with increased incident CI risk (A2: OR\u2009=\u20091.801, 95% CI: 1.111\u20132.920; A3: OR\u2009=\u20092.650, 95% CI: 1.541\u20134.557).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Impaired kidney function, indicated by reduced eGFR and elevated ACR, is independently associated with an increased risk of cognitive impairment in older adults.
