Subject Area:
Most of the early research I was involved in concerned the evaluation of various PA assessment methods (i.e. PA surveys and the Caltrac accelerometer).
Continued research efforts concerning PA assessment included studying different populations and evaluating intra-individual variability in PA.
Also we investigated PA levels in a large sample of adolescents.
More recently my focus has included the assessment of PA by motion sensors (accelerometers and pedometers) for determination of health outcomes (primarily obesity), validation, descriptive, and intervention purposes. We investigated the relationship between youth body mass index (BMI) and several parent and child factors.
