Relationship of anthropometric indices to abdominal and total body fat in youth: sex and race differences.
Bottom Line: Regression was used to examine sex and race effects in the relationship between independent (BMI, WC, and W/Ht) and dependent (FM, SAT and VAT) variables.The association of BMI with FM and SAT was independent of sex and race, while the relationships of WC and W/Ht with FM and SAT were influenced by both sex and race.In contrast, the association between BMI and VAT was influenced by sex and race, while the relationships of WC and W/Ht with VAT were not.

Mentions: There was a significant linear relationship between BMI and FM (p < 0.0001), and neither age, sex, nor race were related to FM after adjusting for BMI (Figure 1A). In addition to BMI, age was significantly associated with levels of SAT (p < 0.001); however, no other main effects or interactions were significant (Figure 1B). For VAT, age, sex, and race had significant main effects in the BMI model (all p < 0.04). The interactions between BMI x sex and BMI x race were also significant. For a given BMI, whites had more VAT than AA. At low BMI levels AA girls had more VAT than AA boys, but this relationship was reversed at high BMI levels (Figure 1C).
