- Study investigates the link between daily dietary vitamin C intake and chronic kidney disease (CKD) prevalence in older adults using NHANES 1999-2018 data.
- Included 6,540 participants aged 60 years or older, analyzing vitamin C intake (excluding supplements) and CKD prevalence.
- Found an inverse association: higher vitamin C intake linked to lower CKD prevalence (OR per 1 mg increase = 0.998).
- Highest quartile of vitamin C intake showed significantly lower CKD prevalence compared to the lowest quartile (OR = 0.778).
- Developed a predictive nomogram model with good discrimination (AUC = 0.737 in training, 0.715 in validation sets) and clinical utility.
- Nomogram may aid in CKD risk assessment for older adults based on dietary vitamin C intake.
