Background: We compared moderate-to-vigorous intensity physical activity (MVPA) and inactivity levels among fifth and sixth graders during school hours according to school-level race/ethnicity and income attributes to inform school-based obesity interventions in Illinois Suburban Cook County (SCC). Methods: Fifth- and sixth-grade students…

Background: This study examined the association between physical fitness and academic achievement and determined the influence of socioeconomic status (SES) on the association between fitness and academic achievement in school-aged youth. Methods: Overall, 1,701 third-, sixth-, and ninth-grade students from 5 school districts participated in the…

Background: Research on physical fitness often regards socioeconomic status (SES) as a confounding factor. However, few studies investigate the impact of SES on fitness.
