Outline of Final Research Achievements

Dual-energy X-ray absorptiometry (DXA) allows for direct determination of regional (arm, leg, appendicular, and trunk) fat mass. Various DXA-based fat distribution indices have been reported, including trunk-to-leg fat mass ratio (TLR) and trunk-to-appendicular fat mass ratio (TAR). In the present large-scale community-based follow-up study, we investigated body fat distribution, as measured by DXA (TLR and TAR), and cardio-metabolic profiles in Japanese children. Our findings suggest that childhood body fat distribution is affected by growth processes of children and maternal lifestyle, and that body fat distribution has an impact on cardio-metabolic profiles of children. Assessment of regional body fat distribution by DXA may provide additional insight into the evaluation of cardio-metabolic risk.
