Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="oby20504-sec-0001" sec-type="section"> <title>Objective</title> <p>A recently developed parameter, the body adiposity index (BAI)—a composite index based on hip circumference and height—estimates the percentage (%) body adiposity indirectly. The BAI was compared with dual energy X‐ray absorptiometer (DEXA)‐derived % adiposity to validate the BAI in the local Chinese population.</p> </sec> <sec id="oby20504-sec-0002" sec-type="section"> <title>Design and Methods</title> <p>105 Chinese were recruited and % adiposity estimated by BAI was compared with that derived from DEXA using the Bland Altman plot. A correlation study comparing the BAI with body mass index (BMI) was also done.</p> </sec> <sec id="oby20504-sec-0003" sec-type="section"> <title>Results</title> <p>BAI underestimated DEXA‐derived % adiposity by a mean of 5.77% with 95% limits of agreement of ±8.4%. When stratified by gender, BMI correlated with DEXA‐derived % adiposity better than BAI (<italic>r</italic> = 0.81 vs. 0.74 for males, <italic>P</italic> = 0.088, and <italic>r</italic> = 0.87 vs. 0.82 for females, <italic>P</italic> = 0.087). Hip circumference and waist circumference also correlated better with the BMI than BAI (<italic>r</italic> = 0.94 vs. 0.71 for hip circumference, <italic>P</italic> < 0.001, and <italic>r</italic> = 0.93 vs. 0.50 for waist circumference, <italic>P</italic> < 0.001, respectively).</p> </sec> <sec id="oby20504-sec-0004" sec-type="section"> <title>Conclusions</title> <p>The BAI underestimates DEXA‐derived % adiposity in a Chinese population in Singapore and is unlikely to be a better overall index of adiposity than the established BMI.</p> </sec> </abstract>
