| Non-human primates are valuable models for the study of insulin resistance and human obesity. In baboons, insulin sensitivity levels can be evaluated directly with the euglycemic clamp and is highly predicted by adiposity, metabolic markers of obesity and impaired glucose metabolism (i.e. percent body fat by DXA and hemoglobin A1C). However, a simple method to screen and identify obese insulin resistant baboons for inclusion in interventional studies is not available. We characterized a population of obese nondiabetic, insulin resistant baboons using the euglycemic clamp technique and used a multivariate linear regression analysis (after adjustment for gender) to test three different predictive models for insulin sensitivity. In the first model, abdominal... |
