As the obesity epidemic overtakes Africa, practical methods to measure percent body fat need identification. Possibilities which have not been validated in Africans are the Body Adiposity Index (BAI), which uses hip circumference and height and the same formula for men and women, and bioelectric impedance (BIA) derived from NHANES III data and uses different equations for men and women. Using dual-energy X-ray absorptiometry (DXA) scans as the reference method, 107 Africans (71% male; age 39.5∓10.3 y, range 22 to 64 y; BMI 27.9∓4.5 kg/m 2 , range 19.7 to 41.2 kg/m 2 ) had percent body fat assessed in two ways. Method 1 was: BAI (Hip circumference/Height 1.5 )-18). Method 2 was: BIA (Men: weight - (-10.678 + 0.262*weight + 0.652*height 2 /resistance + 0.015*resistance))/weight*100; Women: (weight - (-9.529 + 0.168*weight + 0.696*height 2 /resistance + 0.016*resistance))/weight*100)). Percent body fat by DXA, BAI and BIA are shown in the Figure. Concordance was between 0.5 and 0.6 with P <0.001 for DXA and BAI as well as between DXA and BIA. Bland-Altman analyses revealed the BAI estimated percent body fat with a mean difference of 1.1% and limits of agreement of -9.7 and 11.9. With BIA the mean difference was 6.0% and the limits of agreement were -2.3 and 14.4.The BAI and BIA are similar in accuracy, but BAI is easier to apply as it requires only hip circumference and height measurements and uses the same equation for men and women. Therefore, BAI is a superior measure of body fat for both clinical and epidemiological studies in Africans.

Background: The prevalence of type 2 diabetes (T2D) has increased recently in Qatar. Body mass index (BMI) is a predictor of T2D in many populations. However, BMI is based on height and weight measurements and not on body adiposity. Therefore, the utility of BMI for predicting the risk of T2D has been questioned, and visceral adiposity (VAI) appears to be a better predictor of T2D. Objective: This study is aimed to assess the relative effectiveness of visceral adiposity index (VAI) and body adiposity index (BAI), in comparison with body mass index (BMI), for T2D among Qatari adults. Methodology: A random sample of 1103 adult Qatari nationals over 20 years old were included in this study; this data was obtained from the Qatar National Biobank. We performed a multivariate logistic regression to examine the association between VAI, BAI, BMI, and T2D, and computed zscores for VAI, BAI and BMI. Results: VAI z-scores showed the strongest association with the risk of T2D (OR, 1.44; 95% CI: 1.24–1.68) compared with the zscores for BAI (OR, 1.15; 95% CI: 0.93–1.43) and BMI (OR, 1.33; 95% CI: 1.11–1.59). Subgroup analyses indicated that the association was stronger between VAI and T2D in Qatari women than in men. Conclusion: VAI was a strong and independent predictor of T2D among the Qatari adult population. Therefore, VAI could be a useful tool for predicting the risk of T2D among Qatari adults.
