Frequency and Validity of Dichotomized Accelerometry and EVS Categories of Physical Activity (Simple Kappa=0.34)

Physical activity categorization by EVS^a	Physical activity categorization by accelerometry^a
Physical activity categorization by EVS^a	Inactive N (%)	Active N (%)	Total N
Inactive	149 (66.8)	96 (32.2)	245
Active	74 (33.2)	202 (67.8)	276
Total, n	223	298	521

Notes: Sensitivity: 67% (95% CI=61%, 73%); Specificity: 68% (95% CI=62%, 73%); Positive predictive value (PPV): 61% (95% CI=55%, 67%); Negative predictive value (NPV): 73% (95% CI=68%, 78%).

Inactive defined as 0–149 minutes per week. Active defined as ≥150 minutes per week.

EVS, exercise vital sign.
