Table 2. Regression coefficients (ß) and 95% CI for percentage body fat by sex and TV class unadjusted (Model 1) and adjusted (Model 2) for physical activity.

Regression coefficients represent estimated mean differences in percentage body fat between groups. Data are weighted by probability of membership.

	Percentage Body Fat
	Females	P value	Males	P value
Model 1	ß (95% CI)	Overall p <0.001	ß (95% CI)	Overall p = 0.102
Class 2 vs 1	-2.820 (-4.947 to -0.722)	0.006	-1.895 (-3.713 to -0.006)	0.045
Class 3 vs 1	-4.133 (-6.277 to -2.140)	<0.001	-1.768 (-4.529 to 0.829)	0.192
Class 3 vs 2	-1.312 (-3.527 to 0.697)	0.235	0.127 (-2.727 to 2.699)	0.927
Model 2	ß (95% CI)	Overall p <0.001	ß (95% CI)	Overall p = 0.001
