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. …

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 …

The Relationship Of Physical Activity, Eating Behaviors, And Hunger Control To Weight Loss And Quality Of Life In Gastric Banding Patients, Nancy Baugh

Theses and Dissertations

Gastric banding as a weight loss surgery has increased in popularity in the United States since its approval by the Food and Drug Administration in 2001. Successful weight loss after weight loss surgery is most frequently defined as greater than 50 percent of excess weight loss (EWL). Systematic reviews show that the band is widely effective in achieving successful weight loss in most patients, however individual studies show more inconsistent outcomes. Although previous research supports gastric bypass surgery as having a positive effect on quality of life after gastric bypass, there is very little data to support this relationship in …

Efficacy Of A Family Practice-Based Lifestyle Intervention Program To Increase Physical Activity And Reduce Clinical And Physiological Markers Of Vascular Health In Patients With High Normal Blood Pressure And/Or High Normal Blood Glucose (Snac): Study Protocol For A Randomized Controlled Trial, Robert Petrella, Kuni Aizawa, Kevin Shoemaker, Tom Overend, Leonard Piché, Mauricio Marin, Sheree Shapiro, Sophie Atkin

Leonard Piché

BACKGROUND: Previous interventions to increase physical activity and reduce cardiovascular risk factors have been targeted at individuals with established disease; less attention has been given to intervention among individuals with high risk for disease nor has there been determination of the influence of setting in which the intervention is provided. In particular, family practice represents an ideal setting for the provision and long-term maintenance of lifestyle interventions for patients at risk (ie high-normal blood pressure or impaired glucose tolerance).

METHODS/DESIGN: The Staged Nutrition and Activity Counseling (SNAC) study is a randomized clustered design clinical trial that will investigate the effectiveness …
