Equating Accelerometer Estimates Of Moderate-To-Vigorous Physical Activity: In Search Of The Rosetta Stone, Daniel B. Bornstein, Michael W. Beets, Wonwoo Byun, Gregory J. Welk, Matteo Bottai, Marsha Dowda, Russell R. Pate

Faculty Publications

Purpose - No universally accepted ActiGraph accelerometer cutpoints for quantifying moderate-to-vigorous physical activity (MVPA) exist. Estimates of MVPA from one set of cutpoints cannot be directly compared to MVPA estimates using different cutpoints, even when the same outcome units are reported (MVPA min•d^-1). The purpose of this study was to illustrate the utility of an equating system that translates reported MVPA estimates from one set of cutpoints into another, to better inform public health policy.

Design - Secondary data analysis.

Methods - ActiGraph data from a large preschool project (N=419, 3-6yr-olds, CHAMPS) was used to conduct the analyses. …

The Importance Of Self-Efficacy And Basic Psychological Needs In Children’S Physical Activity: Measurement, Prediction And Intervention, Casey E. Gray

Electronic Thesis and Dissertation Repository

The importance of physical activity in the overall health promotion and primary prevention of cardiovascular disease risk factors and metabolic diseases in children is well established. Nonetheless, interventions to increase physical activity among this population have been largely unsuccessful. The main objective of the research in this dissertation was to explore the suitability of self-efficacy and basic psychological needs for physical activity prediction and intervention in children. Item generation and psychometric evaluation of psychological questionnaires occurred in study 1 (Chapter 2). Using a prospective design, study 2 (Chapter 3) established task efficacy, barriers efficacy, competence, and autonomy as significant predictors …

Exploring Student Perceptions To Explain The Relationship Between Physical Activity And Academic Achievement In Adolescents: A Mixed Methods Study, Megan J. Hylok

College of Education and Human Sciences: Dissertations, Theses, and Student Research

A nationwide survey conducted by the Center for Disease Control in 2007 reported 65% of high school students did not meet the recommendation that youth participate in at least 60 minutes of physical activity most days of the week (CDC, 2008). While research has focused its attention primarily on bodily health, growing evidence supports the benefits of physical activity on brain health (Ratey & Hagerman, 2008). Physical activity is important and many adolescents are not meeting the recommendation, therefore, it is important to explore the adolescent perceptions to understand which factors influence physical activity participation. The significance of this study …

Perceived Familial Socialization And Ethnic Identity: Factors Associated With Physical Activity, Eating Behavior Patterns, And Social Physique Anxiety In African American Middle Adolescents, Nutrena H. Tate

Wayne State University Dissertations

Purpose: African American adolescents experience higher rates of obesity and have an increased risk of obesity related diseases than Caucasian American adolescents. Despite culturally sensitive obesity preventive interventions, obesity rates are increasing within the African American adolescent population. Current obesity interventions claim to be culturally sensitive, but do not address how ethnic identity and parental influences on body image and body change may affect the efficacy of the interventions. The purpose of this study was to examine the sociocultural factors related to weight behaviors and cognitions in African American adolescents. Differences based on socioeconomic status (SES), gender, and residential status …

Objective Physical Activity And Sleep Characteristic Measurements Using A Triaxial Accelerometer In Eight Year Olds, Susan Ann Harrington

Wayne State University Dissertations

Background: Secular trends demonstrate that young children are less active and sleep less. Inequity in an individual's energy balance is known to have poor health outcomes. Academic achievement, academic behavior, and weight status are proxy indicators for health and psychosocial outcomes in this study. Current guidelines in place for sleep and physical activity in childhood are the result of data collected in the form of self-reports. Quantification and qualification of physical activity dimensions and sleep characteristics are essential not only for the purpose of clearly establishing parameters but also for the intent of verifying optimal health outcomes and evaluating interventions …

Comparison Of Three Physical Activity Measurement Tools To Assess Physical Activity Guideline Compliance In Children, Emily C. Huber, Andrew M. Litz
