Abstract
BACKGROUND Chronic kidney disease (CKD) awareness could help prevent disease progression through modifiable risk factors. However, few patients with CKD are aware of their disease. We aimed to investigate the factors associated with CKD awareness and impact of CKD awareness on renal prognosis. METHODS We investigated the proportion of participants with CKD who answered 'aware of CKD' in the questionnaire among those undergoing health check-ups from 2013 to 2022. Participants included working-age employees and their dependents covered by health insurance associations for large and medium-sized companies. The outcome was defined as the change from 'unaware' to 'aware' of CKD; multivariable logistic regression analysis assessed the association of urine tests or nutritional guidance with CKD awareness. A control group was randomly selected from the unaware group and matched for age, sex, estimated glomerular filtration rate (eGFR), urinary protein categories, and follow-up period. Changes in eGFR slopes before and after awareness were compared using linear mixed-effects models. RESULTS Of the 13,489 participants, 2.8% were aware of CKD at baseline; of the 1,614 with CKD-related disease codes, only 19.6% were aware. The odds ratios of urine tests or nutritional guidance in relation to awareness occurrence were 1.98 (1.29-3.05) and 3.01 (1.38-6.53), respectively. The difference in the eGFR slope improvement from before to after CKD awareness was + 0.92 mL/min/1.73 m2 per year (0.18-1.67; P = 0.015) in the aware group. CONCLUSION Our findings suggest that urine tests and nutritional guidance may promote CKD awareness, which may help slow its progression.

Abstract
The rapid growth of the elderly population is making the need for extensive and advanced information about age-related organ dysfunction a crucial research area. The kidney is one of the organs most affected by aging. Aged kidneys undergo functional decline, characterized by a reduction in kidney size, decreased glomerular filtration rate, alterations in renal blood flow, and increased inflammation and fibrosis. This review offers a foundation for understanding the functional and molecular mechanisms of aging kidneys and for selecting identifying appropriate targets for future treatments of age-related kidney issues.
