We assessed whether lipid profile components mediate and synergize with systemic inflammation, indexed by the neutrophil-to-lymphocyte ratio (NLR), in relation to DPN. In a cross-sectional study in Indonesia (July 2023-January 2024), 738 participants completed questionnaires, laboratory testing, and sensory screening with a 10-g Semmes-Weinstein monofilament and 128-Hz tuning fork. Multivariate logistic regression showed that an abnormally increased NLR (AOR 8.39; p < 0.001), total cholesterol (AOR 3.10; p < 0.001) and LDL-C (AOR 2.25; p < 0.001) were independently associated with a higher DPN risk. Combined abnormalities markedly amplified the risk (AOR 33.30; p < 0.001). Path analysis supported partial mediation of the NLR-DPN association via LDL-C and total cholesterol (total indirect β = 0.03; 95% CI 0.02-0.05; p < 0.001).
