FEAST: Empowering Community Residents to Use Technology to Assess and Advocate for Healthy Food Environments.

Creating environments that support healthy eating is important for successful aging, particularly in light of the growing population of older adults in the United States. There is an urgent need to identify innovative upstream solutions to barriers experienced by older adults in accessing and buying healthy food. FEAST (Food Environment Assessment STudy) is an effort that is part of the global Our Voice initiative, which utilizes a combination of technology and community-engaged methods to empower citizen scientists (i.e., community residents) to: (1) use the Healthy Neighborhood Discovery Tool (Discovery Tool) mobile application to collect data (geocoded photos, audio narratives) about aspects of their environment that facilitate or hinder healthy living; and (2) use findings to advocate for change in partnership with local decision and policy makers. In FEAST, 23 racially/ethnically diverse, low-income, and food-insecure older adults residing in urban, North San Mateo County, CA, were recruited to use the Discovery Tool to examine factors that facilitated or hindered their access to food as well as their food-related behaviors. Participants collectively reviewed data retrieved from the Discovery Tool and identified and prioritized important, yet feasible, issues to address. Access to affordable healthy food and transportation were identified as the major barriers to eating healthfully and navigating their neighborhood food environments. Subsequently, participants were trained in advocacy skills and shared their findings with relevant decision and policymakers, who in turn dispelled myths and discussed and shared resources to address relevant community needs. Proximal and distal effects of the community-engaged process at 3, 6, 12, and 24 months were documented and revealed individual-, community-, and policy-level impacts. Finally, FEAST contributes to the evidence on multi-level challenges that low-income, racially/ethnically diverse older adults experience when accessing, choosing and buying healthy foods.

Successful recruitment of monolingual Spanish speaking Latinos to university phase II and III outpatient COVID-19 clinical treatment trials in Northern California.

Through a public County/University partnership, we employed a Spanish/English bilingual research coordinator to increase awareness of newly available treatments with FDA Emergency Use Authorization and clinical trial opportunities for Latino outpatients with mild to moderate COVID-19. Out of the 550 San Mateo County outpatients with COVID-19 referred to Stanford University between July 2020 and April 2022, 9.5% elected to receive monoclonal antibody EUA treatment. COVID-19 treatment trial enrollment of County patients, 5% of those recruited, was commensurate with non-County populations enrollment. Recruitment models such as ours have the potential to increase US Latino populations' recruitment in outpatient COVID-19 treatment trials and contribute to decreasing COVID-19 health disparities.

The effectiveness of two community-based weight loss strategies among obese, low-income US Latinos.

BACKGROUND: Latino immigrants have high rates of obesity and face barriers to weight loss. OBJECTIVE: To evaluate the effectiveness of a case-management (CM) intervention with and without community health workers (CHWs) for weight loss. DESIGN: This was a 2-year, randomized controlled trial comparing two interventions with each other and with usual care (UC). PARTICIPANTS/SETTING: Eligible participants included Latinos with a body mass index of 30 to 60 and one or more heart disease risk factors. The 207 participants recruited during 2009-2010 had a mean age of 47 years and were mostly women (77%). At 24 months, 86% of the sample was assessed. INTERVENTION: The CM+CHW (n=82) and CM (n=84) interventions were compared with each other and with UC (n=41). Both included an intensive 12-month phase followed by 12 months of maintenance. The CM+CHW group received home visits. MAIN OUTCOME MEASURES: Weight change at 24 months. STATISTICAL ANALYSES: Generalized estimating equations using intent-to-treat. RESULTS: At 6 months, mean weight loss in the CM+CHW arm was -2.1 kg (95% CI -2.8 to -1.3) or -2% of baseline weight (95% CI -1% to -2%) compared with -1.6 kg (95% CI -2.4 to -0.7; % weight change, -2%, -1%, and -3%) in CM and -0.9 kg (95% CI -1.8 to 0.1; % weight change, -1%, 0%, and -2%) in UC. By 12 and 24 months, differences narrowed and CM+CHW was no longer statistically distinct. Men achieved greater weight loss than women in all groups at each time point (P<0.05). At 6 months, men in the CM+CHW arm lost more weight (-4.4 kg; 95% CI -6.0 to -2.7) compared with UC (-0.4 kg; 95% CI -2.4 to 1.5), but by 12 and 24 months differences were not significant. CONCLUSIONS: This study demonstrated that incorporation of CHWs may help promote initial weight loss, especially among men, but not weight maintenance. Additional strategies to address social and environmental influences may be needed for Latino immigrant populations.
