title: Relationships of objectively measured physical activity and sleep with BMI and academic outcomes in 8-year-old children.
abstract: Current guidelines in place for sleep and physical activity in childhood are the result of data collected in the form of self-reports. Exact measurement of activity dimensions and sleep characteristics are essential. The purpose of clearly established parameters is for the intent of verifying health outcomes and evaluating interventions. The purpose of this research was to determine the relationships between the objective dimensions of physical activity, sleep, weight status, academic achievement, and academic behavior. This cross-sectional correlational descriptive design examined the activity and sleep patterns continuously for 24 hours/7 days with triaxial accelerometers in a low income African American sample of 8-year-olds. A qualitative component gathered additional identifiers. This sample was overweight/obese, inactive, and sleep-deprived. Moderate-vigorous activity was correlated with reading scores. Confirmed in this research was the association between sleep duration, physical activity intensities, and academics. Positive health outcomes in children are endorsed by an energy balance.
