Background: Evidences have accumulated indicating that intra-abdominal fat distribution contributes to cardiovascular disease (CVD). A simple method for the assessment of fat distribution is Waist/Hip circumferences (cm) Ratio (WHR).
Objective: To evaluate the influence of body fat distribution on segmental impedance measurements and to evaluate the agreement of WHR and segmental (i.e.,arm,trunk and leg) Bioelectric Impedance Analysis.
Subjects: Preliminary we found in 611 subjects that reactance-to-resistance ratio (Xc/R) was significantly positively correlated with the Body Mass Index (BMI:Kg/m2) (p=.03).The (Xc/R)/BMI was significantly correlated with markers of insulin resistance and with basal diastolic pressure,an early alteration of CVD (r=.38;p=.0001). We measured,as proposed by Organ LW et al.(JAppPhysiol77(1),98,1994),"virtual"Truncal reactance to Truncal resistance ratio (vTXc/vTR) in 30 obese female (BMI=35.8±sd9.8) and in 34 control subjects [22Female/12Male] (BMI=22.2±3.4).
Results: The WHRs were similar between the control groups,but the vTXc/vTR was significantly higher in the control than in the obese (p<.03).In a multiple linear regression analysis,with vTXc/vTR as dependent variable, neither BMI and age,but only WHR contributed to the variance of vTXc/vTR (R2=.43;p=.02).
Conclusions: These results shown a clear association between vTXc/vTR ratio and WHR in estimating central fat distribution.Therefore, the vTXc/vTR,as early marker of central obesity together with its, possibly,association with diastolic disfunction could be proposed as prognostic marker of CVD.
