Regression coefficients (95%CI) for models predicting the dependent variable, %BF, by sequentially including gender (model 1), BMI (model 2), age (model 3), lean mass (model 4) and BMC (model 5) as independent variables.

CI = confidence interval; %BF = percentage body fat; gender: men = 1, women = 0; BMI = body mass index (kg/m2); age (yr); mean BMI = 26.37 kg/m2; lean mass (kg); BMC = bone mineral content (kg); S = standard error of the regression.Polynomial relationships were centred about the mean to reduce collinearity. Interaction terms are also included.
