this may provide further insight into possible differences in
non-exercise thermogenesis within these populations. Future
studies should also include subjects with a wider age range, as
cardiometabolic risk factors differ with age.
Conclusion
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 TC and LDL-C concentrations in the
white women. Increased central and reduced peripheral FM
were independently associated with measures of IR in both the
black and white women. In addition to body fat distribution,
modifiable risk factors were identified, including MVPA, which
were associated with reduced IR in the white women, and
contraceptive use, which was associated with IR and lipid levels
in the black and white women. Intervention studies aimed at
reducing centralisation of body fat, increasing physical activity
and changing contraceptive use are required to verify these
findings in order to provide evidence-based guidelines for the
prevention and management of cardiometabolic risk.
