n = number; TEE = total energy expenditure; AEE = active energy expenditure; PA = physical activity.
Values represented as means ± standard deviation. Comparisons between gender and race groups were completed using independent t-tests when data was normally distributed and Mann-Whitney U-test for non-normally distributed data.
^a p < 0.05 Girls vs Boys.
^b p < 0.05 Black vs White.
