Obesity is the major risk factor for the development of many diseases. BMI is widely used as a deputy measure of obesity, but underestimates the prevalence of obesity, defined as an excess of body fat. The aim of this study was to investigate the relationship between body mass index (BMI) and body fat percentage (BF%) in females. The study was a cross-sectional design. A selected sample of 70 f...

This study compared the two following hydrodensitometric methods for estimating percent body fat (%BF): 1) estimation of residual volume (RV) by helium dilution before and after measurement of immersed mass at RV, and 2) determination of immersed mass at a comfortable level of expiration (approximately functional residual capacity) with measurement of the associated gas volume by oxygen dilutio...

Breast volume and body composition were measured in 45 adult females to determine the contribution of breast weight and breast volume to total body fat. Plaster casts were filled with sand of known density to obtain breast volume. Breast weight was computed as breast volume times its density. The correlation between total breast volume and percent body fat was r = .40. Breast weight (mean = 484...

Result: The average body mass index (BMI) for males was 28.2 kg/m and for females was 28.6 kg/m. This increased with age, showing a biphasic increase for females. Linear transformation of BMI data showed greater significance in correlating BMI versus percent body fat. However, prediction equations for calculation of percent body fat were more accurate without linear transformation of data. Perc...
