Faster biological aging and body balance problems linked to diabetic kidney disease: Evidence from population data and genetic analysis

Abstract

Accelerated biological aging status (BioAgeAccel > 0) substantially increased diabetic kidney disease (DKD) odds (OR = 3.25, 95% CI: 2.52-4.18).

  • Significant nonlinear threshold effects were observed, with DKD risk increasing markedly at BioAgeAccel > 2.13 years and (HD) > 3.16 units.
  • PhenoAgeAccel exhibited a linear dose-response relationship with DKD risk.
  • The highest quartile of HD was associated with elevated risk (Q4 OR = 2.85, 95% CI: 1.87-4.36).
  • Urinary albumin-to-creatinine ratio mediated 89% to 93% of the associations between all aging metrics and DKD.
  • Discriminatory accuracy for HD was highest (AUC = 0.678), followed by BioAgeAccel (AUC = 0.660) and PhenoAgeAccel (AUC = 0.562).
  • Mendelian randomization confirmed a causal effect of PhenoAgeAccel on DKD risk, but not for BioAgeAccel.
