Baseline and end-of-year data were collected on BMI,BMI percentile, healthy habits and physical activity. This was facilitated through support from the Mayo Clinic Mobile Clinical Research Unit (MCRU, funded by a National Institutes of Health Clinical Translational Science Award) which is a recreation vehicle converted into a mobile clinical unit with examination rooms and a waiting room. One of the examination rooms included a calibrated digital scale and stadiometer (Scale-Tronix 5005 Stand-On Scale, White Plains, NY) that was used to collect height and weight. BMI percentile was determined using Centers for Disease Control (CDC) growth charts.
