Registration Number: NCT03041415

Lead Sponsor: Stanford University

Brief Summary: While low-income midlife and older adults are disproportionately affected by chronic diseases that can be alleviated by regular physical activity, few physical activity programs have been developed specifically with their needs in mind. Those programs that are available typically do not address the recognized local environmental factors that can impact physical activity. This research aims to evaluate the added effects on two-year physical activity levels of a novel citizen science neighborhood engagement program (called Our Voice) when combined with an evidence-based, individually-focused physical activity program (Active Living Every Day), relative to the individually-focused program alone. The programs will be delivered in affordable housing settings, and represent a potentially scalable means for promoting physical activity across broader income groups in the US.

Detailed Description: The major objective of this project is to enhance the potential scalability and sustainability of person-level physical activity (PA) interventions by leveraging the capacity of residents themselves as local data gatherers and solution generators for neighborhood environmental change. The primary aim of the group-randomized trial is to systematically compare the sustained (two-year) multi-level impacts of a lay advisor-delivered, person-level PA intervention that has demonstrated efficacy and translatability (Active Living Every Day) \[ALED Alone arm\], versus the ALED program in combination with a novel neighborhood-level intervention, called Our Voice \[ALED+Our Voice arm\]. The Our Voice program teaches residents to use a simple mobile application to individually and collectively identify neighborhood barriers to daily PA. They then convey this information to local stakeholders and decision-makers in ways that can facilitate potentially sustainable neighborhood-level improvements in support of regular PA. Up to sixteen affordable housing sites serving low-income, ethnically diverse midlife and older adults will be randomized to one of the two interventions.

Arm && Interventions

Group	Intervention	Description
ALED Alone Physical Activity Program	ALED Alone Physical Activity Program	* The Active Living Every Day (ALED) comprehensive 12-week PA training and support program is appropriate for delivery by trained instructors from diverse backgrounds. * Participants are taught self-regulatory skills aimed at increasing and sustaining regular physical activities such as walking.
ALED + Our Voice PA Program	ALED + Our Voice PA Program	* The ALED physical activity program is combined with the Our Voice citizen science engagement program, which teaches participants how to assess the barriers and enablers of neighborhood physical activity using a simple mobile app. * Residents then share their data and build consensus around major barriers and potential solutions, which they share with local decision makers.

Primary Outcome Measures

Name	Time	Method
Weekly Walking Minutes	12 months	Self-report using the Community Healthy Activities Model Program for Seniors (CHAMPS) Physical Activity Questionnaire. CHAMPS is a self-report physical activity questionnaire that assesses weekly frequency and duration of various activities typically undertaken by midlife and older adults over the prior 4-week period. Self-reported walking for errands is one physical activity item assessed. The measure has been shown to have good test-retest reliability (stability) and construct and concurrent validity, and has been shown to be sensitive to change in a variety of adult populations. It has seven frequency categories (from less than 1 hour a week to 9 or more hours per week). The minimum value is 0 and the maximal value is variable.
