The atherogenic index of plasma was positively and non-linearly associated with the risk of prediabetes, with a 41% increased risk for every unit increase in AIP (HR 1.41).

Does a higher atherogenic index of plasma increase the risk of incident prediabetes in Chinese adults?
The atherogenic index of plasma is positively and non-linearly associated with the risk of developing prediabetes, suggesting its potential utility as a biomarker for early glucose dysmetabolism.
Hazard Ratio: 1.41 (95% CI 1.31–1.52)

BACKGROUND: The atherogenic index of plasma (AIP) can reflect the burden of atherosclerosis. Hyperglycemia is one of the leading causes of atherosclerosis. However, the relationship between AIP and prediabetes is rarely studied. Therefore, we aimed to explore the relationship between AIP and prediabetes. METHODS: This retrospective cohort study recruited 100,069 Chinese adults at the Rich Healthcare Group from 2010 to 2016. AIP was calculated according to Log10 (triglyceride/high-density lipoprotein cholesterol) formula. Cox regression method, sensitivity analyses and subgroup analyses were used to examine the relationship between AIP and prediabetes. Cox proportional hazards regression with cubic spline functions and smooth curve fitting was performed to explore the non-linearity between AIP and prediabetes. The two-piece Cox proportional hazards regression model was used to determine the inflection point of AIP on the risk of prediabetes. RESULTS: After adjusting for confounding covariates, AIP was positively associated with prediabetes (HR: 1.41, 95%CI: 1.31-1.52, P 0.03, their association was not significant (HR: 1.04, 95%CI: 0.91-1.19, P = 0.5528). CONCLUSION: This study shows that AIP was positively and non-linearly associated with the risk of prediabetes after adjusting for other confounding factors. When AIP ≤ 0.03, AIP was positively associated with the risk of prediabetes.
Zheng et al. (2023) conducted a cohort in Prediabetes (n=100,069). Atherogenic index of plasma (AIP) vs. Lower AIP levels was evaluated on Incident prediabetes (HR 1.41, 95% CI 1.31-1.52, p=< 0.0001). The atherogenic index of plasma was positively and non-linearly associated with the risk of prediabetes, with a 41% increased risk for every unit increase in AIP (HR 1.41).
