dc.description.abstractBackground: Individuals of black ethnicity tend to have less visceral fat (VAT) but more subcutaneous-abdominal fat (SCAT) than white Caucasians. However, it is unclear whether such distribution of abdominal fat is beneficial for metabolic disease risk in black individuals. Here we examined the associations between these specific abdominal fat compartments and metabolic syndrome risk. Methods: 76 black South African young adults (36 men; 40 women) aged 18-19 years participating in the Birth to Twenty Cohort Study had VAT and SCAT measured by MRI. The metabolic syndrome traits (blood pressure, lipid profile, fasting glucose and insulin) were measured and the values were combined into a metabolic syndrome risk score. Results: Compared to men, women had greater VAT (mean: 16.6 vs. 12.5 cm2; p=0.005) and SCAT (median 164.0 vs. 59.9; p=0.0001). In men, SCAT (r=0.50) was more strongly related to the metabolic syndrome score than was VAT (r=0.23), and was independently associated with MetS (P=0.004) and HOMA-IR (P<0.001) after adjustment for VAT. In women, both abdominal fat compartments showed similar positive correlations with the metabolic syndrome score (r=0.26 to 0.31), although the associations were weaker than in men. In men and women combined, SCAT explained the sex difference in HOMA-IR (adjusted p-value for sex =0.08). Conclusions: In black South Africans, SCAT may be more relevant than VAT to metabolic syndrome traits at the younger ages. Their tendency to accumulate SCAT rather than VAT is unlikely to be beneficial to metabolic syndrome risk.
