RELATIONSHIP OF BODY-FAT PERCENTAGE AND FAT DISTRIBUTION WITH DEHYDROEPIANDROSTERONE-SULFATE IN PREMENOPAUSAL FEMALES

Dehydroepiandrosterone (DHEA) has an antiobesity effect in rodents, an d elevated endogenous levels of its sulfate ester (DHEAS) are associat ed with reductions in risk for cardiovascular disease (CVD) in men. To examine the association of body fat and fat distribution, established correlates of CVD and CVD risk factors, with circulating DHEAS levels in women, we measured trunk and limb skinfold thicknesses and circumf erences, total and regional body fat from dual energy x-ray absorptiom etry (DXA), and serum levels of DHEAS in 96 healthy Caucasian females aged 28-39 yr. Body mass index, percentage fat from DXA and the waist- to-hip ratio were not significantly correlated (r less-than-or-equal-t o 0.15, P greater-than-or-equal-to 0.156) with serum DHEAS levels, reg ardless of statistical control for age, smoking behavior, and fasting status. However, the ratio of trunk/total skinfold thicknesses (r = 0. 23, P = 0.030) and the percentage of total fat located on the trunk fr om DXA (r = 0.32, P = 0.002) were positively correlated with DHEAS, wh ereas the ratio of leg/total skinfold thicknesses (r = -0.25, P = 0.01 5) and the percentage of total fat located on the legs from DXA (r = - 0.25, P = 0.015) were inversely correlated with DHEAS after adjusting for age, smoking, and fasting status. With the exception of the trunk/ total skinfold thickness ratio, the correlations of DXA- and skinfold- derived estimates of fat distribution remained significant (P less-tha n-or-equal-to 0.033) even after further adjustment for percentage fat or body mass index. It is concluded that increased amounts of total fa t located on the trunk and decreased amounts of total fat located on t he legs are associated with increased serum DHEAS concentrations in no rmally menstruating females.
