Body Fat Distribution and Insulin Resistance in Healthy Asian Indians and Caucasians

Abstract

Previous studies have shown that Asian Indians (AIs) are insulin resistant and at high risk for developing diabetes and coronary heart disease, compared with Caucasians. To examine whether differences in body fat distribution contribute to this risk, 12 healthy AIs and 12 Caucasians matched for age and body mass index (BMI) underwent a 75-g oral glucose tolerance test, 2-h euglycemic hyperinsulinemic clamp, abdominal (L2-3) computed tomography scan, and fasting lipid and plasminogen activator inhibitor-1 (PAI-1) levels. Despite similar fasting plasma glucose levels, AIs exhibited fasting hyperinsulinemia (P = 0.001), higher glucose (P = 0.03) and insulin (P = 0.004) levels during the oral glucose tolerance test, and reduced glucose disposal rate (R(d)) (4.7 +/- 0.4 vs. 7.5 +/- 0.3 mg/kg per min, P < 0.0001) during the clamp. AIs had significantly lower high-density lipoprotein, higher low-density lipoprotein, and significantly higher PAI-1 levels (P = 0.01). Despite similar BMI, AIs had significantly greater total abdominal fat (P = 0.04) and visceral fat (P = 0.04). In all subjects, measures of fat mass were inversely correlated with R(d) during the clamp (r = -0.47 to -0.61, P < 0.01-0.001). Visceral fat mass was correlated with triglycerides, low-density lipoprotein, and high-density lipoprotein (P < 0.002-0.0001). PAI-1 was inversely correlated with R(d) in AIs (r = -0.70, P < 0.01) and not in Caucasians (r = -0.24, P = 0.44). For comparable BMI and age, healthy AIs have physiologic markers for insulin resistance, dyslipidemia, and increased cardiovascular risk, compared with Caucasians. Alterations in body fat distribution--particularly increased visceral fat--may contribute to these abnormalities.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
