Physical activity has many benefits for health and wellness. Physical activity can help us control our weight, reduce our risk of diseases including many cancers and type 2 diabetes, help to strengthen our bones and muscles, and improve our mental health. Yet despite the benefits, many don’t get the recommended amount of physical activity. Our guest this week, Evan Hilberg from the College of Public Health and Human Sciences and the Department of Kinesiology, is investigating factors that influence physical activity of children in rural communities. Research focused on physical activity in children disproportionally centers around children in urban communities. Children in rural communities may have different limitations to physical activity. For example, rural children are more likely to take the bus to school instead of walking and commutes may take up to two hours each way. This leaves little time for physical activity outside of school hours. With his advisors, John Schuna and Kathy Gunter, Evan is analyzing data collected as part of the Generating Rural Options for Weight- Healthy Kids and Communities (GROW HKC) to better understand when children are active during the school day and factors that might limit their physical activity.
Recess and Wellness

One area of interest for Evan and the GROW HKC project are the variables that may predict changes in Body Mass Index (BMI) over a three-year period. Through this longitudinal study that involves over 1000 rural Oregon elementary school children, Evan will identify correlates of BMI change such as physical activity levels, age, sex, teacher, and school. Additionally, Evan is analyzing data that will hopefully provide more insight into specifically what times during the school day children are active. By obtaining a classroom schedule from teachers and measuring activity with accelerometers and pedometers, Evan can infer if children are physically active during recess, P.E., classroom activity breaks, or other times during the school day. Finally, Evan’s data will examine the reliability of different objective measures of physical activity, such as pedometers and accelerometers. The ability to compare outputs from different devices is limited by changes in device hardware and software, as well as the ways in which data is processed within those devices. The examination of these devices may inform procedure for future physical activity research for children and adults to help comparability across different devices and different studies.
A School of Thought
A clear understanding of the factors effecting physical activity in rural school children will aid in structuring the school day to maximize each child’s opportunity to be physically active. Data generated through GROW HKC my reveal patterns that younger children are more active during unstructured play during recess, whereas older children prefer sports-focused activity in P.E.. This type of research could inform recommendations for state-mandated physical activity at schools such that school day structure and physical activity opportunities are tailored to the diverse needs of kids in rural communities.
Full Circle
Evan grew up as an active kid and selected a college where he could play baseball. He landed at Linfield College in McMinnville, Oregon where his interest in Exercise Science grew through volunteering in community health outreach and research with his advisor, Janet Peterson. Evan learned that his education went beyond the classroom through his interactions with the community. Evan decided to pursue graduate school and earned a Master’s degree in Exercise Physiology from Eastern Washington University. During his Master’s, Evan gained more experience with community and public health research as an AmeriCorps employee with “Let’s Move, Cheney”, a local coalition inspired by Michelle Obama’s national campaign. Thereafter, Evan volunteered with the GROW HKC project, and applied to graduate school at Oregon State. Since beginning his doctoral studies with a concentration in physical activity and public health, Evan has completed a Master’s in Public Health in Biostatistics and maintains a full-time job as a Medical Policy Research Analyst with Cambia Health Solutions.
