In March 2020, federal and state telehealth policy changes catalyzed telemedicine adoption and use in community health centers. There is a dearth of evidence on telemedicine implementation and use in these safety net settings and a lack of information reflecting the perspectives of patients with limited English proficiency. We conducted in-depth interviews with clinic personnel and patients during the pandemic in two federally qualified health centers that primarily serve Chinese and Latino immigrants. Twenty-four interviews (clinic personnel ​= ​15; patients who primarily speak a language other than English ​= ​9) were completed remotely between December 2020 and April 2021. Interview scripts included questions about their telemedicine experiences, technology, resources and needs, barriers, facilitators, language access, and continued use, with a brief socio-demographic survey. Data analyses involved a primarily deductive approach and thematic analysis of transcript content. Both FQHCs adopted telemedicine in a few weeks and transitioned primarily to video and audio-only visits within two months. Findings reveal third-party language interpretation services were challenging to integrate into telemedicine video visits. Bilingual personnel who provided language concordant care were seen as essential for efficient and high-quality patient telemedicine experiences. Audio-only visits were of particular benefit to reach patients of older age, with limited English proficiency, and with limited digital literacy. Continued use of telemedicine is contingent on reimbursement policy decisions and interventions to increase patient digital literacy and technological resources. Results highlight the importance of reimbursing audio-only visits post-pandemic and investing in efforts to improve the quality of language services in telemedicine encounters.

Objectives: We explored how perceived barriers and facilitators influence healthy eating and investigated the acceptability of changes to school lunch meals among adolescents after implementation of the Healthy, Hunger-Free Kids Act of 2010. Methods: We conducted 8 focus groups with adolescents (N = 64) at 3 South Los Angeles high schools. Data collection instruments included a semi-structured guide and questionnaire. Two researchers independently coded transcripts. Results: Most participants believed fruits and vegetables were available in their community and reported high relative cost, poor quality, and lack of motivation as barriers to consumption. Many said school meals were an important source of healthy food and were aware of recent changes to the school lunch program. A primary facilitator to eating school lunches was access to fresh food items (eg, a salad bar). Perceived barriers included long cafeteria lines, time constraints, lack of variety, and limited quantities of preferred items. Adolescents viewed off-campus food establishments near the school as competition to school meals. Conclusions: Our findings suggest the need to measure perceived and actual barriers to healthy eating among adolescents and to examine the effect of these barriers on dietary behavior. We provide programmatic and policy recommendations.

Purpose: To implement a multilevel, church-based intervention with diverse disparity populations using community-based participatory research and evaluate feasibility, acceptability, and preliminary effectiveness in improving obesity-related outcomes. Design: Cluster randomized controlled trial (pilot). Setting: Two midsized (∼200 adults) African American baptist and 2 very large (∼2000) Latino Catholic churches in South Los Angeles, California. Participants: Adult (18+ years) congregants (n = 268 enrolled at baseline, ranging from 45 to 99 per church). Intervention: Various components were implemented over 5 months and included 2 sermons by pastor, educational handouts, church vegetable and fruit gardens, cooking and nutrition classes, daily mobile messaging, community mapping of food and physical activity environments, and identification of congregational policy changes to increase healthy meals. Measures: Outcomes included objectively measured body weight, body mass index (BMI), and systolic and diastolic blood pressure (BP), plus self-reported overall healthiness of diet and usual minutes spent in physical activity each week; control variables include sex, age, race–ethnicity, English proficiency, education, household income, and (for physical activity outcome) self-reported health status. Analysis: Multivariate linear regression models estimated the average effect size of the intervention, controlling for pair fixed effects, a main effect of the intervention, and baseline values of the outcomes. Results: Among those completing follow-up (68%), the intervention resulted in statistically significantly less weight gain and greater weight loss (−0.05 effect sizes; 95% confidence interval [CI] = −0.06 to −0.04), lower BMI (−0.08; 95% CI = −0.11 to −0.05), and healthier diet (−0.09; 95% CI = −0.17 to −0.00). There was no evidence of an intervention impact on BP or physical activity minutes per week. Conclusion: Implementing a multilevel intervention across diverse congregations resulted in small improvements in obesity outcomes. A longer time line is needed to fully implement and assess effects of community and congregation environmental strategies and to allow for potential larger impacts of the intervention.

Food insecurity contributes to poor health outcomes among people living with HIV. In Latin America and the Caribbean, structural factors such as poverty, stigma, and inequality disproportionately affect women and may fuel both the HIV epidemic and food insecurity. We examined factors contributing to food insecurity among women living with HIV (WLHIV) in the Dominican Republic (DR). Data collection included in-depth, semi-structured interviews in 2013 with 30 WLHIV with indications of food insecurity who resided in urban or peri-urban areas and were recruited from local HIV clinics. In-person interviews were conducted in Spanish. Transcripts were coded using content analysis methods and an inductive approach to identify principal and emergent themes. Respondents identified economic instability as the primary driver of food insecurity, precipitated by enacted stigma in the labor and social domains. Women described experiences of HIV-related labor discrimination in formal and informal sectors. Women commonly reported illegal HIV testing by employers, and subsequent dismissal if HIV-positive, especially in tourism and free trade zones. Enacted stigma in the social domain manifested as gossip and rejection by family, friends, and neighbors and physical, verbal, and sexual abuse by intimate partners, distancing women from sources of economic and food support. These experiences with discrimination and abuse contributed to internalized stigma among respondents who, as a result, were fearful and hesitant to disclose their HIV status; some participants reported leaving spouses and/or families, resulting in further isolation from economic resources, food and other support. A minority of participants described social support by friends, spouses, families and support groups, which helped to ameliorate food insecurity and emotional distress. Addressing food insecurity among WLHIV requires policy and programmatic interventions to enforce existing laws designed to protect the rights of people living with HIV, reduce HIV-related stigma, and improve gender equality.

Problem, research strategy, and findings: Farmers' markets provide one option for remedying the startling decline in fresh vegetable and fruit consumption in the United States, particularly in low-income, non-White neighborhoods where opportunities to access these components of a healthy diet are often limited. We lack empirical research on whether farmer's markets provide fresh vegetables and fruits consistently across locations. We audited product offerings at 24 farmers' markets in Los Angeles at two points in time and interviewed a sample of market managers to compare market offerings across neighborhoods to determine whether farmers' markets alleviate disparities experienced by low-income and non-White communities. Farmers' markets in low-income and non-White communities are smaller and provide fewer fresh fruits and vegetables than markets situated in more affluent communities. Managers suggest that their first priority is to stock fresh produce, but other factors such as competition and farmer recruitment and retention often influence market offerings. Takeaway for practice: Planners cannot count on farmers' markets to fully remedy disparities in the availability of fresh vegetables and fruits. We need additional research to understand the range of social, ecological, and health benefits created by farmers' markets in a neighborhood. Planners should begin working with other agencies to conduct community food assessments to better evaluate strategies for addressing inequalities seen in neighborhood access to healthy food.
