Abstract

To examine the relationship between baseline, post, and follow-up accelerometer derived physical activity (PA) in 9-10 year old children participating in iCook 4-H, a 16-week, 5- state, randomized control family centered childhood obesity prevention program. This family focus intervention was designed to promote PA through lifestyle modifications. Between group differences in minutes-per-day and intensity of PA were determined on accelerometer compliant participants. All subjects wore an accelerometer (Actigraph GT3X+) for 7 days at baseline, post, and follow-up intervention assessment. Mean daily minutes of accelerometer derived sedentary time (ST) and PA including light (LPA), moderate (MPA), vigorous (VPA) and moderate-to-vigorous (MVPA) were evaluated during waking hours (7am-9pm). A multivariate test, Wilks’ Lambda, was used to determine the between group differences of PA from baseline, post, and follow-up. Statistical significance was set at p ≤ 0.05. There were no significant differences between groups due to the intervention at any intensity category of PA (mean min/day±SD; p-value). Although there was not a significant increase in any category of physical activity due to the lifestyle intervention, iCook 4-H was able to encourage participants to maintain current activity levels.
