MEHDIZADEH, R. Relationship between body water compartments and indexes of adiposity in sedentary
young adult girls. Brazilian Journal of Biomotricity. v. 6, n. 2, p. 84-92, 2012. Changes in Total body water
(TBW) that occur with variation of body weight (BW), indicating a relation between body water content and
adipose tissue mass, because BW changes directly relate to changes in FM content in adults. The aim of the
study was first to determine the relationship between TBW, extra- and intra cellular water (ECW and ICW)
with some indexes of overall and central adiposity. Three hundred and forty eight young adult girls (18-24yrs)
volunteered to participate in this study. After fasting for at least 12 h, body water components (TBW, ECW,
and ICW), indexes of overall obesity including body mass index (BMI), body fat percentage (%BF) and fat
mass (FM) and central obesity including waist-to-hip circumference ratio (WHR) were measured by Body
Composition Analyzer. There were significant positive correlations between WHR, FM and %BF with body
water compartments including TBW (P<0.01), ECW (P<0.01) and ICW (P<0.01). Overall adiposity may be
determined by using body water compartments and body water compartments as simple, low-cost and quick
techniques are more appreciate for estimating overall obesity than central obesity.
