Purpose: The primary purpose of this research study was to assess the degree of agreement between simple anthropometric measurements (i.e. body mass index, waist circumference, hip circumference, and waist-to-hip ratio) and the measures of regional adiposity, with a primary focus on the androidlgynoid ratio, assessed using dual energy x-ray absorptiometry (DXA). This secondary purpose of the study was to identify any significant correlations between the measures of regional adiposity, physical activity, and cardiovascular risk factors. Methods: Forty-eight subjects, 19 males (48.7 ± 16.9 years) and 29 females (43.6 ± 16.2 years), volunteered to participate in this study. Subjects underwent laboratory testing compromised of resting blood pressure, blood lipid analysis, waist & hip circumference, total body DXA scan, and a one week physical activity assessment. Results: Significant correlations were observed between body mass index and region body fat % (r = 0.84, 0.79), waist circumference and android fat % (r = 0.79, 0.75), and waist-to-hip ratio and androidlgynoid ratio (r = 0.72, 0.61) for men and women, respectively. Fasting insulin was correlated with region body fat %, android body fat %, trunk body fat %, and the android/gynoid ratio. The android/gynoid ratio was correlated with high density lipoproteins, very low density lipoproteins, triglycerides, and fasting glucose. There was a statistically significant negative relationship observed between average steps per day and body mass index, waist circumference, hip circumference, region body fat %, android body fat %, and trunk body fat %. Conclusions: This study found that there are strong relationships between simple anthropometric measures and regional body fat measures from the DXA. According to the data in the present study, body mass index, waist circumference, and waist-to-hip ratio provide simple yet sensitive methods for the estimation of regional body fat in Caucasian males and females. In addition, this study found significant correlations between measures of the blood lipid profile, physical activity, and both simple anthropometric and DXA measures of regional body fat.
