Relationship of Physical Activity Self-Efficacy and Psycho behavioral Characteristics of Overweight and Obese African American Children

Background:Different movement efficiency in overweight children may affect accelerometer output data. The purpose was to investigate the ability of accelerometers to assess physical activity intensity and number of steps in normal-weight compared with overweight children.Methods:Eleven normal-weight and 14 overweight African American children walked at 2, 4, 5, and 6 km/h on a treadmill wearing Lifecorder, ActiGraph, RT3, and Biotrainer. Oxygen uptake was measured and steps manually counted. Fat free mass (FFM) was assessed from bioelectrical impedance analysis. Accelerometer counts and the individual linear regression lines of accelerometer counts versus VO2/FFM were evaluated, together with steps recorded by Lifecorder and Actigraph.Results:Correlations between accelerometer counts and VO2/FFM for all monitors were r ≥ .95 (P < .01). The accelerometer counts and their relationship to VO2/FFM did not generally differ significantly by body weight status. Lifecorder and Actigraph underestimated steps at 4, 5, and 6 km/h by less than 9%, but the error was up to −95% at 2 km/h.Conclusions:All 4 accelerometers show high ability to assess physical activity intensity, and can be used to compare physical activity between normal-weight and overweight children. The Lifecorder and the ActiGraph showed high accuracy in assessing steps, providing speed of movement exceeded 2 km/h.

Similarity Scores

Background:The research sought to find the salient perceived characteristics of playgrounds for African-American children and their parents, and to test effects of changes in those characteristics on playground choice.Methods:Thirty-one African-American children and their parents sorted 15 photographs of playgrounds for similarity. Nonmetric multidimensional scaling on the similarity scores and correlations between the resulting dimensions and judged characteristics of each playground revealed salient perceived characteristics. Study 2 had 40 African-American children and their parents view pairs of photographs, manipulated on the salient characteristics, and pick the one to play on (child question) or for the child to play on (parent question). A third study inventoried and observed children’s activities in 14 playgrounds.Results:Study 1 found seats, fence, playground type, and softness of surface as salient perceived characteristics of the playground. Study 2 found that participants were more likely to pick playgrounds with equipment and playgrounds with a softer surface. Study 3 found higher levels of physical activity for playground settings with equipment.Conclusions:The findings confirm correlational findings on the desirability of equipment and safety. Communities need to test the effects of changes in playgrounds.
