RESEARCH ACTIVITIES IN PHYSICAL ACTIVITY

Introduction

Recently Published Articles

The Department of Epidemiology and Biostatistics has a strong tradition of physical activity research. Faculty interests in this area are broad and diverse and cover the spectrum from the micro level to the macro level. Current research studies include examining the influence of the built environment on adolescent physical activity in an urban environment, and investigating the impact of physical activity on cancer, diabetes, birth outcomes, and mother's health around pregnancy. Students can capitalize on the collaborative work being conducted with other departments and centers within the Arnold School of Public Health and across the university.

Methods for Improved Diet and Exercise Measurement
Hebert, J. R. (PI)
NIH/NCI/Oregon Research Institute
May 1, 2007 – April 30, 2008
This study will design and test an interactive computer (CD-ROM) assessment program to improve the accuracy of self-reported portion size and self-reported PA intensity in older, overweight, or obese adults, and assess the extent to which these improvements result in increased accuracy, by comparing the CD-ROM assessment program to standard paper/pencil versions and against more objective “gold standard” measures of diet and PA.

Health Promotion and Disease Prevention Research Center
Natalie Colabianchi Ph.D. (Co-I)
CDC
September 30, 2004 - September 29, 2009
The major goal of this project is to reduce the burden of chronic diseases through primary prevention of risk factors associated with the leading causes of death and disability. Includes a community-based participatory demonstration project (quasi-experimental design) to increase physical activity through changes in policy and environment.

This randomized clinical trial will evaluate various methods of weight loss intervention targeting diet and physical activity.
