Body adiposity index in Colombian elite athletes: A comparison between the body mass index and other measures

AbstractPurposeTo evaluate the correlations between body adiposity index and other adiposity indexes such as body mass index, hip and waist circumference, waist-to-hip ratio, Σ6 skinfold-thickness and percentage body fat in Colombian elite athletes.MethodsA cross-sectional study was conducted in 149 elite athletes from Colombia (mean age: 26.3±6.5 years; height: 169.2±10.1cm; body mass: 66.1±12.8kg; body mass index 22.9±3.0kgm−1). body adiposity index, body mass index, waist-to-hip ratio, percentage body fat, Σ6 skinfold-thickness and waist circumference were also measured.ResultsTo select an optimal surrogate for adiposity, we examined the correlation between body adiposity percentage as measured by BIA and several variables, including body adiposity index, body mass index, Σ6 skinfold-thickness, percentage body fat and waist-to-hip ratio. The regression procedure showed that there was a significant relationship between the body adiposity index and BF% (R2=0.407, p<0.01). Bland–Altman plot showed that the limits of agreement (95% confidence intervals) between the BF% and body adiposity index ranged between 15.53 and 2.26%, and there was a significant positive association between the difference and mean of the 2 methods (rho=0.607, p
