Abstract: Objectives Alleviating racial/ethnic disparities in physical activity (PA) and health outcomes during childhood becomes an important public health priority as the nation’s populace continues to diversify. Guided by expectancy-value model, the purposes of this study were (a) to examine the potential differences in expectancy-value beliefs, PA and health-related quality of life (HRQOL) between African-American (AA) children and their American-Caucasian (AC) peers, and (b) to determine how the relationships among these variables might differ between the two racial groups.Method Participants were 321 (152 boys; 189 AC) children from three schools who completed a previously validated questionnaire assessing their expectancy-value beliefs in physical education, leisure-time PA (PAQ-C), and HRQOL.Results Students’ PA was positively associated with HRQOL among AC and AA children (p < .01). AA children had significant higher expectancy-value beliefs but lower HRQOL than AC children. The regression results revealed that both racial groups had a nearly identical effect of expectancy beliefs on their self-reported PA (ß = .34 in AA group, ß = .33 in AC group, respectively). The regression analysis also suggests that expectancy-value belief was a significant predictor of HRQOL while controlling for all other variables (ß = .36; p < .001) for the AC group, but not the AA group.Conclusions The growing health disparities across racial/ethnic subgroups are of great public health concern. Thus, this study provided valuable insights regarding how to promote AA children’s PA and HRQOL through an expectancy-value approach.
