To investigate the association between alpha-1-acid glycoprotein (AGP) and prediabetes prevalence in US adults.
We analyzed data from 2 926 participants (age ≥18 years) in the National Health and Nutrition Examination Survey (2017-2023). Participants were classified into prediabetes and non-prediabetes groups. AGP levels were measured and analyzed both as continuous and quartile-categorized variables. Weighted logistic regression models were employed to assess this relationship after adjusting for covariates.
The prediabetes group showed significantly higher AGP levels (0.79±0.02) versus controls (0.78±0.01; P<0.001). In fully adjusted models, each unit increase in AGP was associated with 7.8% higher prediabetes risk (OR=1.08, 95%CI:1.453-1.842). Quartile analysis revealed progressively increasing risks from Q2 to Q4 versus Q1 (all P<0.05). Subgroup analyses showed stronger associations in females (OR=1.01,95%CI:1.095-2.778, P=0.043) and younger adults (18-39 years; OR=1.22, 95%CI:1.182-7.965, P=0.008).
Elevated AGP levels are consistently associated with increased prediabetes risk, suggesting its potential as a novel biomarker for early risk identification.
