SES, physical activity, and academic achievement from middle childhood through early adolescence
Hypotheses: 1) As PA increases, executive functioning and concentration increase resulting in improved academic achievement, 2) the effect of SES on academic achievement is partially mediated by executive functioning and concentration as a consequence of PA, 3) Higher SES predicts greater PA leading to increased executive functioning and concentration resulting in improved academic achievement. The National Institute of Child Health and Human Development Study of Early Child Care and Youth Development dataset (N = 1032) was analyzed at ages 9 (2000), 11 (2002), 12 (2003), and 15 (2006). Hypotheses were confirmed using a mediational path model. Greater PA predicted improved academic achievement (beta = -2.58, SE = 0.78; p < .001). Increased executive functioning (beta = 0.11, SE = 0.03; p < .001) and concentration (beta = 0.07, SE = 0.02; p < .01) mediated this relationship. Higher SES predicted improved academic achievement (beta = -2.15, SE = 0.90; p < .05). Additional path analyses will test the full mediational model.
This study's demonstration of the pathways through which PA improves academic achievement will provide policy-makers with research evidence to design school-based interventions crucial to preventing childhood obesity.
Learning Areas:Planning of health education strategies, interventions, and programs
Identify the relationship between PA on academic achievement from middle childhood through early adolescence. Assess the degree to which executive functioning and concentration mediate the relationship between PA and academic achievement. Analyze the antecedent role of SES in predicting PA in the model.

Qualified on the content I am responsible for because: I am a Doctoral Candidate in Psychology and Research Assistant to the Graduate Center Doctoral Nursing Program with extensive training in quantitative methods; specifically, path analyses, hierarchical linear modeling, and structural equation modeling. Notably, this study is my dissertation project. Among my scientific interests has been the development of strategies for preventing childhood obesity in school settings (e.g., physical education program, in-class academically-oriented exercise programs).
