The DII was calculated based on the 24-hour dietary history interview, while the SII was calculated as the product of platelet count multiplied by neutrophil count and divided by lymphocyte count. CKD was diagnosed based on impaired glomerular filtration rate (&lt;60 mL/min per 1.73 m²) or urinary albumin-creatinine ratio ≥30 mg/g.

The prevalence of CKD changed from 14.84% (95% confidence interval (CI): 13.20-16.48%) in 1999-2000 to 12.76% (95% CI: 11.10-14.43%) in 2017-2018. According to adjusted multivariate logistic regression models, individuals with higher DII scores had a higher likelihood of having CKD (odds ratio = 1.24; 95% CI: 1.12-1.37). Similarly, higher SII scores were associated with a higher risk of CKD (odds ratio = 1.37; 95% CI: 1.25-1.50).
