Abstract
SummaryAimThe aim was to examine differences in body fat distribution between premenopausal black and white South African (SA) women and explore the ethnic-specific associations with cardiometabolic risk.MethodsBody composition, using dual-energy X-ray absorptiometry (DXA) and computerised tomography, insulin resistance (HOMA-IR) and lipid levels were assessed in 288 black and 197 white premenopausal SA women.Results:Compared to the white women, black women had less central and more peripheral (lower-body) fat, and lower serum lipid and glucose concentrations, but similar homeostasis models for insulin resistance (HOMA-IR) values. The associations between body fat distribution and HOMA-IR, triglyceride and high-density lipoprotein cholesterol concentrations were similar, while the associations with fasting glucose, total and low-density lipoprotein cholesterol levels differed between black and white women.Conclusion:Ethnic differences in body fat distribution are associated, in part, with differences in cardiometabolic risk between black and white SA women.
Highlights
Partial correlations were used to determine the associations between the various body fat distribution variables and cardiometabolic outcomes in the black and white women, adjusting for age and Fat mass index (FMI)
FMI was chosen as the covariate because it takes into account both the total body fat and the height of an individual
This study showed that black women had lower central and greater peripheral fat compared to white women, which was associated with lower fasting glucose concentrations in the black women and higher total cholesterol (TC) and LDL-C concentrations in the white women
Summary
The aim was to examine differences in body fat distribution between premenopausal black and white South African (SA) women and explore the ethnic-specific associations with cardiometabolic risk. The aim of this study was to examine differences in whole-body fat distribution between premenopausal black and white women and to explore the ethnic-specific associations with cardiometabolic risk
