Abstract
Introduction: Body composition analysis is one of the necessary aspects in nutrition as it gives us information about the body fat and lean body mass. Among many common techniques used for analysis of body composition for humans, bioelectric impedance analysis (BIA) , skin fold measurements are the inexpensive and easy methods in comparison to sophisticated technique such as DEXA. DEXA is precise and gives detailed information about fat distribution for variety of clinical and research applications. Nevertheless, the technique is expensive and tedious. On the other hand, bioelectric impedance analysis is simple electrical impedance based technique which calculates the total body water to estimate Fat Mass (FM) or Fat Free Mass (FFM). Thus, the aim of the study was to investigate whether there is a difference between body fat mass percentage measured by BIA and DEXA method. Methodology: The study conducted on 30 male subjects who were randomly selected with mean age 23.71 ± 4.7 years and BMI=25.5 kg/m2. Height was measured by seca rod to minimum 0.1cm. The body fat % was measured with both bioelectric impedance analyzer and DEXA scan. Results & Conclusion: The mean difference between the body fat mass percentage measured by BIA and DEXA was 4.38 with a standard deviation of 2.95. DEXA and BIA showed high correlation in FM, FFM and %BF correlation by Pearson’s and Spearman’s correlation. Student’s paired t-test showed no significant change.
