Relationships of several measures of bone mineral density (dependent variables) with serum reproductive hormone concentrations, body composition, and physical activity by stepwise multiple regression

	FSH	LH	P	E	InhB	Age	LBMI	Fat, %	LTPA	Model (r2, P)
Total BMD	−0.26		0.34				0.44		0.52	0.65, <0.0001
Total hip						−0.41			0.32	0.23, 0.01
Femoral neck						−0.42	0.32			0.31, 0.002
Total lumbar	−0.52									0.27, 0.001

Values are standardized regression coefficients for each statisitically significant independent variable. The last column of the table provides the r² and P values for each of the overall regression models. Independent variables: FSH, LH, progesterone (P), estradiol (E), inhibin-B (InhB), age, LBMI, %fat, and LTPA.
