Estimating Minutes of Physical Activity from the Previous Day Physical Activity Recall: Validation of a Prediction Equation.

In this study, school children wore a validated accelerometer and completed the Previous Day Physical Activity Recall for three consecutive days. When applied to the holdout sample, an algorithm of predicted minutes of moderate to vigorous physical activity showed good agreement with the actual accelerometer minutes, providing a valid and useful metric to help interpret results.
