Objective

To evaluate the association of body adiposity index (BAI) with all-cause and cardiovascular disease (CVD) mortality risk.

Design and Methods

The current analysis comprised 19,756 adult men who enrolled in the Aerobics Centre Longitudinal Study and completed a baseline examination during 1988-2002. All-cause and CVD mortality was registered till December 31, 2003.

Results

During an average follow-up of 8.3 years (163,844 man-years), 353 deaths occurred (101 CVD deaths). Age- and examination year-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for all-cause mortality risk were higher for men with high values of BMI (HR = 1.63, 95% CI = 1.19-2.23), waist circumference (1.55, 1.22-1.96), and percentage of body fat (%BF) (1.36, 1.04-1.31), but not for men with high values of BAI (1.28, 0.98-1.66). The HRs for CVD mortality risks were higher for men with high values in all adiposity measures (HRs ranged from 1.73 to 2.06). Most of these associations, however, became nonsignificant after adjusting for multiple confounders including cardiorespiratory fitness.

Conclusion

BAI is not a better predictor of all-cause and CVD mortality risk than BMI, waist circumference, or %BF.
