Body adiposity index as a risk factor for the metabolic syndrome in postmenopausal Caucasian, African American, and Filipina women

摘要

Aims: To investigate the utility of the body adiposity index (BAI) and its association with the metabolic syndrome (MetS) in older Caucasian (n = 369), African American (n = 336) and Filipina (n = 275) women. Methods: Dual energy X-ray absorptiometry, anthropometric measures, plasma glucose and medical history were assessed in 1993-1999. Results: Despite smaller body size, 32.7% of Filipina women had higher MetS compared to African American and Caucasian women based on the National Cholesterol Education Program (NCEP) (32.7% vs 19.6% and 13.3%, respectively) or the International Diabetes Federation (IDF) (42.6% vs 33.0% and 18.7%, respectively ps < 0.05). BAI had higher positive correlations with BMI, %body fat (%BF), and %truncal fat in Caucasian than African American and Filipina women. Adjusted for age, smoking, estrogen use, exercise, and alcohol intake, odds of the MetS (NCEP) were 2.08 (95%CI: 1.52-2.85) by BAI, 3.04 (95%CI: 2.11-4.38) by BMI, and 2.13 (95%CI: 1.52-3.00) by %BF for Caucasian women; 0.92 (95%CP. 0.69-1.23) by BAI, 1.44 (95%CI: 1.09-1.90) by BMI, and 1.12 (95%CI: 0.84-1.50) by %BF for African American women; and 1.14 (95%CI: 0.88-1.47) by BAI, 1.51 (95%CI: 1.15-1.97) by BMI, and 0.96 (95%CI: 0.74-1.25) by %BF for Filipinas. Conclusion: BAI was better able to assess adiposity in postmenopausal Caucasian women compared to African American and Filipina women. This index can distinguish ethnic differences in MetS confirmed by%BF.
