Research - Open for Recruitment



The major objective of the COMPASS Study is to develop and test programs that provide support and advice to encourage Latino adults to be more physically active over the span of 12 months. Participants will be randomized to either a culturaly appropriate and personally tailored Virtual Advisor program, or a similarly tailored Lay Advisor program. This study is currently open to recruitment.

We are seeking Latinos over the age of 50 that do not engage in regular physical activity and are willing to work with a Lay or Virtual advisor to increase their physical activity level. For more information regarding COMPASS, please call us at 1-650-723-9530 or toll free at 1-844-254-6777, or email us at healthyaging@stanford.edu. We are bilingual.

Research Projects


Lifestyle Interventions and Independence for Elders (LIFE) Study

The LIFE Study was a Phase 3, multicenter randomized controlled trial that compared a moderate-intensity physical activity program to a successful aging health education program in sedentary older persons that were at risk of disability. The primary aim was to assess the long-term effects of the interventions on major mobility disability. Secondary aims focused on assessing the relative effects of the interventions on the following secondary outcomes: cognitive function; serious fall injuries; persistent mobility disability; disability in activities of daily living; and cost-effectiveness. This study is closed to recruitment.



NEAAT: Neighborhood Eating and Activity Advocacy Team Study

In the NEAAT study, ethnically diverse, low income, older adults were empowered to identify features of their neighborhood environment that helped or hindered active living and healthy eating. The older adults prioritized issues to address, connected with local policy makers, and worked collaboratively to achieve change. We have utilized this citizen scientist approach in numerious studies.

Stanford Healthy Neighborhood Discovery Tool

Subsequent to the NEAAT project, HARTS researchers developed a tablet-based mobile application that can be used by community residents, or citizen scientists, to conduct neighborhood environment assessments.

Nuestra Voz

The aim of this study was to explore the feasibility and utility of utilizing the Stanford Healthy Neighborhoods Discovery Tool in Mexico (Cuernavaca) to assess features of residents neighborhood built environment that promote or hinder physical activity. We used the citizen scientist approach to train community residents to identify and prioritize neighborhood environmental issues and to communicate their findings with key local stakeholders to seek solutions.

FEAST: Food Environment Assessment using the Stanford Tool

The FEAST Study utilized the citizen scientists approach to explore North San Mateo County older adults' food environments using photos and audio recordings captured via the Stanford Healthy Neighborhood Discovery Tool. Through this process, older adults identified and learned about factors that make it easier or harder for them to access, choose, and buy, healthful foods.

Farmers Market

The Discovery Tool was used by farmer's market shoppers in Arizona to better understand factors that enhanced or detracted from their shopping experiences. This information can be used to target informations to increase farmer's market utilization, community-building and social marketing strategies.

Adaptation for Use in Rural Environments

We have collaborated with researchers at Cornell University to test the use of the Discovery Tool by older adults living in rural communities in upstate New York.



Nuestra Voz Mexico

The aim of this study was to explore the feasibility and utility of utilizing the Stanford Healthy Neighborhoods Discovery Tool in Mexico (Cuernavaca) to assess features of residents neighborhood built environment that promote or hinder physical activity.

Discovery Tool - Israel

We are collaborating with representatives from ESHEL, a non-governmental organization focusing on programs and services for older adults and with researchers at Haifa University. They are working with a population of older adults to test the use of the Discovery Tool in three cities in Israel.


The MILES StudyMILES smartphone

The objective of The MILES Study was to compare different "Smartphone"
applications in promoting health and wellness. Participants were randomly assigned to one of four "Smartphone" programs promoting more physical activity, less sitting or healthier eating. This program was designed for sedentary adults aged 45 and older to find ways in becoming healthier. The MILES Study is now closed to recruitment.

The Mi Salud Study

The MILES smartphone applications were translated into Spanish and adapted for use by Latinos.



Peer-led Produce Markets

We evaluated older adults perceptions about peer-led, subsidized markets located in non-traditional settings (community centers and housing sites) in the San Francisco Bay Area.
