Low levels of physical activity are a global pandemic, costing billions of dollars in health care, productivity, and quality of life.

Across all ages, most people do not get enough physical activity. CORA investigators study many environmental barriers to physical activity - such as parks, green space, and other neighborhood characteristics - using objective measurement tools and GIS methods. CORA investigators also utilize modern technology to address these barriers, such as using mobile technology to promote physical activity throughout the day.

Since barriers differ for everyone, our interventions are designed to address the unique needs of each population. Ongoing interventions include those tailored to low-income children, older adults, and patients in cardiac rehabilitation.

PROJECTS

Evaluation of a Walking School Bus Program - "Walking school bus" programs encourage physical activity by organizing children to walk to and from school with adults. This project led by Dr. Jason Mendoza evaluates whether walking schools buses affect physical activity and risk for obesity in low-income and ethnic minority children. Washington Governor Jay Inslee even joined the bus one day! 

Heart Steps - Patients with heart disease often struggle to maintain behavior changes to reduce their disease risk. Heart Steps is a personalized, adaptive mobile health (mHealth) intervention, designed by Dr. Predrag Klasnja, to promote physical activity after cardiac rehabilitation. Heart Steps leverages mobile technology to create robust and sustainable physical activity habits. 

Investigating Sedentary Time in Aging:  New Directions Using Technology (iSTAND) - Low activity levels increase disease and mortality risk, and long periods of sedentary behavior can add to these risks. iSTAND is a technology-enhanced intervention, led by Dr. Dori Rosenberg, that uses objective, wireless technologies to measure sedentary behavior and design a program to reduce it in older adults. The project also uses machine learning algorithms to better understand the link between sedentary behavior and health. 

Study of Preschoolers' Outdoor Time and Physical Activity at Child Care (SPROUT) - In SPROUT, Dr. Pooja Tandon studies the environmental and social determinants of outdoor physical activity at child care. By studying how outdoor play enhances learning and development, in addition to physical activity and weight status, SPROUT provides incentives for early childhood professionals, parents and policy makers to promote these activities.

Take Active Breaks from Sitting (TABS) - Older adults with obesity, in particular, often have low activity levels that may increase their disease risk. As this video shows, Dr. Dori Rosenberg designed TABS to coach older adults to sit less. Early results revealed that 2 months of coaching reduced participants' sitting time by nearly half an hour per day.
