Abstract

The purpose of this study was to examine the relationship between the Block Kids Physical Activity Screener ( BKPAS) and accelerometer derived physical activity in 9-10 year old children participating in iCook 4-H, a 5-state, family-centered, childhood obesity intervention. A cross-sectional study was conducted in 121 children who met accelerometer compliance standards and completed the BKPAS. Physical Activity (PA) and Sedentary Time (ST) were measured by accelerometry and the BKPAS. Children wore an accelerometer (ActiGraph GT3X+) for 7 consecutive days and completed a computerized parent-assisted BKPAS. Mean daily minutes of accelerometer derived PA and ST were evaluated during waking hours (7a-9p). In the BKPAS, average PA and screen-based ST minutes per day were calculated from questions that queried frequency and duration from the previous 7 days. Relationships between accelerometry and the BKPAS were assessed via Spearman Correlation Coefficient. Statistical significance was set at p ≤ 0.05. Accelerometer derived moderate physical activity (MPA) and vigorous physical activity (VPA) were significantly correlated with the corresponding BKPAS variables (r = 0.22, p = 0.01; r =0.19, p= 0.04), respectively, but no association was found for ST (r = 0.13, p = 0.16). Findings from this study support the validity of the BKPAS as self-report measure of moderate and vigorous PA in children
