520 $a Objective. To identify and describe differences in physical activity and sedentary behavior among at risk of overweight (ARO), overweight (OW), and non-overweight (NOW) children using a combination of accelerometers and self-report.
520 $a Methods. One hundred and thirteen healthy boys and girls, ages 8 to 10 years, were recruited from a community health center in New Haven. Exclusion criteria included developmental delay, neurological and physical impairments, acute illness, and conduct disorders. Data were collected between September 2004 and June 2005. From 321 scheduled patient visits, 222 showed (69.2%) and 113 were enrolled (50.9%). Height and weight were measured and used to calculate body mass index and percentile. Children wore the Actical accelerometer for 8 days and completed an activity checklist twice during the monitored period.
520 $a Results. We developed and tested a new algorithm for analyzing accelerometer data that delineated specific patterns of activity behavior between ARO/OW and NOW children. We found several important differences in behaviors between children in different weight groups. First, ARO/OW children spent less time in moderate and vigorous physical activity (MVPA). Even when MVPA was sustained, ARO/OW children had less intense motion suggesting they expend less energy during MVPA. Their behavior pattern frequently included transitioning from MVPA to rest while NOW children often re-engaged quickly in high intensity activity. We also found that ARO/OW children had more sustained sedentary periods compared with NOW children.
520 $a Conclusions. These findings suggest that attention to the intensity and duration of MVPA and sedentary behavior is critical to tailoring interventions for ARO/OW children and improving clinical outcomes. ARO/OW children may benefit from strategies that help them to sustain MVPA and re-engage in MVPA after rest. Additionally, increases in MVPA alone without recognizing that intensity of motion may be lower among ARO/OW children may lead to failure to adequately increase energy expenditure. Finally, given the increased number of sedentary periods among ARO/OW children, interrupting sedentary behaviors throughout the day may also improve activity levels.
