Educational Environments And Children's Physical Activity And Sedentary Behaviors, Nathan R. Tokarek

Theses and Dissertations

Children and adolescents spend the majority of their day engaged in sedentary behaviors (SB), while also not meeting physical activity (PA) recommendations. The failure to develop and maintain health enhancing behaviors from a young age may impact an individual throughout their life. With children and adolescents spending a large proportion of their waking hours in a school setting, the educational environment presents an opportunity in which children and adolescents’ PA and SB can be positively influenced. Therefore, the purpose of this dissertation was to explore how children and adolescent’s school time PA and SB are associated with the educational setting, …

A Mixed Methods Evaluation Of An Intersectional Bystander Program Against Sexual Violence Using The Integrated Model Of Behavioral Prediction Within A Cluster Randomized Control Trial, Rose Hennessy

Theses and Dissertations

Background: Sexual violence is a critical public health problem that is particularly salient on college campuses. Bystander intervention is a prevention approach that teaches students who are not directly affected by a situation to take action to help others. Research is needed to understand the relationship between bystander training and changes in behavior to intervene against sexual violence, racism, and unhealthy alcohol outcomes.

Methods: A cluster randomized waitlist control trial was used to evaluate the bystander program Our School TAKES ACTION. Upper-level undergraduate students were randomized by housing floor from buildings of a private, midwestern university. Data was collected in …

Understanding Public Health Professional Socialization And Professional Identity Formation Experiences, Jennifer M. Freiheit

Theses and Dissertations

Public health is in unstable times with funding decreasing, an exodus of retirees, and a paradigm shift with emergency preparedness and response critically changing the identity of the profession. Public health is at a grave trigger point where if something is not done, the entire field may be in jeopardy of caving in to consolidations, poor succession planning, and a field that cannot work toward the health of the public if they themselves are not operating well. It is commonly accepted that orientation practices exist in public health agencies, but the orientations that currently exist lack transfer to full socialization …

The Impact Of Stand-Biased Desks On After-School Physical Activity Behaviors In Children, Nathan Tokarek

Theses and Dissertations

The purpose of this study was to assess changes in after-school time spent performing sedentary behavior (SB), light intensity physical activity (LPA), and moderate to vigorous-intensity physical activity (MVPA) among elementary school children in response to the introduction of stand-biased desks in the classroom. Thirty-one 6th grade participants randomly assigned by their teacher to a traditional (CON) or stand-biased (INT) desk provided complete accelerometer data. After-school PA and SB were measured on four consecutive weekdays at baseline and 10-weeks. Wilcoxon Rank Sum Tests were used to detect significant differences (p<0.10) in changes in the proportion of after-school wear time performing SB and PA between groups. Results suggested no significant differences in changes in after-school time performing SB (p=0.770), LPA (p=0.740), or MVPA (p=0.470). Significant differences in the change in moderate PA (INT: -1.4%; CON: -0.2%, p=0.093) were detected. Stand-biased desks were not detrimental to children’s after-school PA and SB.
