Insulin sensitivity in prepubertal Caucasian normal weight children

Area of Science:

• Pediatric Endocrinology
• Metabolic Health
• Clinical Diagnostics

Background:

• Rising incidence of metabolic complications associated with insulin resistance in childhood necessitates establishing reference values.
• Early identification of insulin resistance in children is fundamental for preventing long-term health issues.

Purpose of the Study:

• To determine the 95th percentile for Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and the 5th percentile for Wright-Biochemical Insulin Sensitivity Index (WBISI) in Caucasian, normal-weight, prepubertal children.
• To establish reliable reference values for diagnosing insulin resistance in this specific pediatric population.

Main Methods:

• Study included 238 normal-weight, prepubertal Caucasian children (126 males, 112 females).
• Anthropometric measurements were taken, followed by an oral glucose tolerance test.
• HOMA-IR and WBISI were calculated from the oral glucose tolerance test results.

Main Results:

• The 95th percentile for HOMA-IR was determined to be 2.03.
• The 5th percentile for WBISI was determined to be 5.67.
• These values serve as cut-off points for identifying insulin resistance.

Conclusions:

• The established reference values for HOMA-IR and WBISI are valuable tools for clinicians.
• These values facilitate the early detection of insulin resistance in prepubertal Caucasian children.
• Early identification allows for targeted interventions to improve insulin sensitivity and prevent complications.
