Data presented are intraclass correlation coefficient (ICC) and Kappa statistic.
Kappa coefficients are based on quartiles of physical activity intensity categories and are weighted
¹ Sedentary activity < 1.5 METS, Light activity 1.5-3 METS, MVPA > 3 METS. MVPA (Moderate & Vigorous Physical Activity)
P-value is a test of non-independence between the two data measures. *P < 0.05; **P < 0.001
