Abstract

BACKGROUND/OBJECTIVES: Adult studies suggest that intra-hepatic fat predicts 2-h blood glucose levels and type 2 diabetes, and may have a role in the development of insulin resistance. Our study objective was to explore relationships between intra-hepatic fat and (i) blood glucose levels and (ii) insulin resistance determined by homeostasis model assessment (HOMA) in a group of obese adolescents.

METHODS: Subjects were 61 obese non-diabetic male and female volunteers aged 12-18 years inclusive with a body mass index >95th percentile for age and 2-h blood glucosedL(-1) . Each subject underwent 2-h glucose tolerance testing and measurement of haemoglobin A1c, ultrasensitive C-reactive protein and fasting insulin. Visceral, subcutaneous abdominal and intra-hepatic fat were determined by magnetic resonance imaging. Intra-hepatic fat was measured by gradient echo chemical shift imaging.

RESULTS: Alanine aminotransferase levels and hepatic phase difference were not significant correlates of fasting or 2-h glucose. In a multiple regression model including hepatic phase difference and visceral fat volume, visceral fat volume was the sole predictor of HOMA.

CONCLUSIONS: This study provides no support to the notion that intra-hepatic fat has a role in the regulation of fasting blood glucose, 2-h postprandial blood glucose or systemic insulin resistance.
