Methods of measuring insulin sensitivity.

Area of Science:

• Endocrinology
• Metabolic Disorders
• Physiology

Background:

• Insulin resistance is a central feature of metabolic disorders, including impaired glucose tolerance and type 2 diabetes mellitus.
• Individuals with insulin resistance exhibit a diminished biological response to insulin, characterized by reduced insulin sensitivity.
• Accurate assessment of insulin sensitivity is crucial for both clinical practice and research.

Purpose of the Study:

• To review and describe various in vivo methods for assessing insulin sensitivity.
• To present the advantages and disadvantages of each method for clinicians and researchers.
• To aid in the selection of appropriate methods based on validity, reproducibility, cost, and subject burden.

Main Methods:

• Description of multiple in vivo techniques for quantifying insulin sensitivity.
• Comparative analysis of assessment methods based on key performance indicators.
• Discussion of practical considerations for method implementation in diverse settings.

Main Results:

• Various in vivo methods exist for measuring insulin sensitivity.
• Each method possesses distinct advantages and disadvantages regarding accuracy, cost, and patient impact.
• The choice of method depends on specific clinical or research objectives.

Conclusions:

• Several in vivo methods are available for assessing insulin sensitivity.
• Understanding the trade-offs of each method is essential for appropriate application.
• Informed selection of insulin sensitivity assessment tools supports effective management of metabolic health.
