Association of the Single Point Insulin Sensitivity Estimator Index with the Risk of Developing Impaired Fasting Glucose in Chinese Adults

Overview

This study investigates the association between the Single Point Insulin Sensitivity Estimator (SPISE) index and the risk of developing impaired fasting glucose (IFG) in a large cohort of Chinese adults. Findings indicate that a higher SPISE index is linked to a significantly lower risk of IFG, suggesting its potential utility in clinical practice for early identification of at-risk individuals.

Background

Diabetes Mellitus (DM) represents a major global health challenge, with China having the highest number of affected individuals. Impaired fasting glucose (IFG) serves as a critical prediabetic state, indicating a heightened risk for progression to DM and associated cardiovascular diseases. Identifying effective tools for predicting IFG risk is essential for implementing timely interventions and preventing the onset of diabetes.

Data Highlights

Key Findings

• A higher SPISE index is independently associated with a lower risk of developing IFG.
• Each one-unit increase in the SPISE index correlates with a hazard ratio of 0.91 for incident IFG.
• Participants in the highest quartile (Q4) of SPISE had approximately 40% lower risk of IFG compared to those in the lowest quartile (Q1).
• RCS analysis demonstrated a linear inverse relationship between SPISE index and IFG risk.
• Subgroup analyses confirmed the robustness of the SPISE index's predictive value across various population characteristics.

Clinical Implications

The SPISE index may serve as a simple and cost-effective tool for identifying individuals at high risk for impaired fasting glucose. Incorporating the SPISE index into routine clinical assessments could enhance early detection and facilitate targeted prevention strategies for diabetes.

Conclusion

The findings underscore the SPISE index's potential role in clinical practice as a predictive marker for impaired fasting glucose, highlighting its importance in diabetes prevention efforts.
