Influence of elbow angle on the reliability and validity of bioelectrical impedance analysis

Hand-to-hand bioelectrical impedance (HH BIA) is a low-cost method to estimate percent body fat (%BF). The BIA method is consistently reliable, but questions on validity remain. We have observed anecdotally that elbow position can render consistently different measures of %BF while using HH BIA, thus leading to the question: Does elbow angle influence the validity of measures derived using HH BIA? The purpose of this study was to assess the effect of elbow position (i.e., IN=flexed to 90° versus OUT=fully extended) on the reliability of HH BIA on 44 male and 24 female healthy adults (age=21±2 yrs, BMI=23±3). An additional aim was to assess the validity of the HH BIA %BF on a subset of subjects (n=12) using air displacement plethysmography (BOD POD®) as the criterion measure. The IN position was ~4%BF lower than the OUT position for HH BIA (p=0.05, effect size=0.67). Measures of %BF for both trials for the IN [intraclass correlation coefficient (ICC)=0.99, coefficient of variation (CV)=2.99%] and OUT (ICC=0.99, CV=1.48%) conditions were highly reliable. On the subsample, the OUT (18.3±6.7 %BF) position exceeded both the IN (14.5±7.4 %BF) and the BOD POD® (16.1±7.8 %BF) measures (p<0.05); however, IN and BOD POD® measures of %BF did not differ (p=0.21). These findings support that HH BIA is a reliable measure at both elbow positions; however, %BF estimations vary considerably (~4%) with respect to the criterion measure depending on elbow position. The OUT position was found to overestimate criteria %BF. Further research may reveal an optimum elbow angle position for HH BIA estimates of %BF.

I, Muhammad Sarwar Khan, am serving as Editor on Archives of Biotechnology and Biomedicine (ABB). I submitted an editorial titled, 'Edible vaccines to combat Infectious Bursal Disease of poultry' for publication in ABB. After submitting the manuscript; the services rendered by the management and technical personnel to handle and process the manuscript were marvelous. Plagiarism report was shared with me with complements before reviewers' comments, All steps including article processing and service charges were well taken care of keeping in view the author's interest/preference. All together, it was an encouraging and wonderful experience working with ABB personnel.
