Abstract

OBJECTIVE: We sought to determine if differences in the distribution and characteristics of adipose tissue between South Asians and white Caucasians account for differences in risk factors for cardiovascular disease. RESEARCH DESIGN AND METHODS: We recruited 108 healthy South Asians (36.8 years) and white Caucasians (34.2 years) within three BMI strata. Body composition, adipocyte size, abdominal fat area, and hepatic adiposity were assessed and related to fasting glucose, insulin, lipids and adiponectin. RESULTS: After adjustment for age, sex, and BMI, South Asians compared to white Caucasians had higher ln fasting insulin (mean difference (MD): 0.44; 95% CI: 0.20-0.69), lower HDL cholesterol (md: -0.13; 95% CI:-0.26 to -0.01), and lower adiponectin (md: -2.38; 95% CI: -3.59 to -1.17). South Asians also had more body fat (md: 2.69; 95% CI: 0.70 to 4.69), lower lean muscle mass (md: -3.25; 95%CI: -5.35 to -1.14), increased waist to hip ratio (md: 0.03; 95% CI: 0.01-0.05), less superficial subcutaneous abdominal adipose tissue (md: -2.94; 95% CI: -5.56 to-0.32), more deep/visceral to superficial adipose tissue ratio (md 0.34; 95% CI: 0.02 to 0.65), and more liver fat (md: 7.43%; 95% CI: 2.30 to 12.55%). Adipocyte area was increased in South Asians compared to white Caucasians (md: 64.26; 95% CI: 24.3 to 104.1) units(2). Adjustment for adipocyte area attenuated the ethnic differences in insulin (md: 0.22; 95% CI: -0.07 to 0.51), HDL (md: -0.01; 95% CI: -0.16 to 0.13) and adiponectin (md: -1.11; 95% CI: -2.61 to 0.39). Adjustment for differences in adipocyte area and fat distribution attenuated the ethnic difference in liver fat (md: 5.19; 95% CI: 0.31 to 10.06). CONCLUSION: South Asians have an increased adipocyte area compared to white Caucasians. This difference accounts for the ethnic differences in insulin, HDL cholesterol, adiponectin, and ectopic fat deposition in the liver.

  • South Asians have higher body fat content, waist to hip ratio, visceral fat to subcutaneous fat ratio, and adipocyte area than Caucasians matched for age, sex, and body mass index (BMI).

    “For example, South Asians have higher body fat content, waist to hip ratio, visceral fat to subcutaneous fat ratio, and adipocyte area than Caucasians matched for age, sex, and body mass index (BMI) (15,16).”

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.
