Digital Storytelling Intervention for Hemoglobin A1c Control Among Hispanic Adults With Type 2 Diabetes: A Randomized Clinical Trial.

Importance: Hispanic adults with type 2 diabetes (T2D) are more likely to develop complications and die from the disease than the US general population. Digital storytelling interventions are narrative-based videos elicited through a community-based participatory research approach to surface the authentic voices of participants overcoming obstacles to health-promoting behaviors that perpetuate health inequities; research on the effect of digital storytelling on T2D outcomes among Hispanic adults is lacking. Objective: To assess the impact of a digital storytelling intervention on glycemic control and its acceptability among Hispanic patients with poorly controlled T2D. Design, Setting, and Participants: This was a multicenter, randomized clinical trial conducted within 2 primary care networks in Minnesota and Arizona among Hispanic adults with poorly controlled T2D (hemoglobin A1c level ≥8%). Enrollment and follow-up were conducted between February 14, 2019, and November 1, 2023. Intervention: The intervention group viewed a 12-minute digital storytelling video. The video included 4 Spanish-language stories that reinforced 4 diabetes self-management behavioral goals (healthful diet for diabetes, physical activity, medication adherence, and glucose self-monitoring). The control group received printed, culturally tailored T2D education materials. Main Outcomes and Measures: The primary outcome was the mean change from baseline to 3 months for hemoglobin A1c levels, adjusting for baseline hemoglobin A1c, age, gender, education, and income. Acceptability and narrative quality of the intervention were assessed through questionnaires. Results: There were 451 study participants, with 227 (mean [SD] age, 54.3 [9.3] years; 158 [69.3%] women) randomized to the intervention group and 224 (mean [SD] age, 54.5 [9.1] years; 156 [69.3%] women) to the control group. Of these, 390 completed 3-month follow-up of the primary outcome (86% retention). There was a small improvement in the mean (SD) hemoglobin A1c level in the intervention group compared with the control group in the adjusted model (9.1% [1.7] to 8.4% [1.6] vs 9.4% [1.8] to 8.8% [2.0]; P = .04] but not in the unadjusted model. Acceptability and narrative quality of the intervention were high. Conclusions and Relevance: In this randomized clinical trial, a digital storytelling intervention developed with and for Hispanic adults with T2D was highly acceptable and feasibly implemented within primary care settings and resulted in a modest improvement of glycemic control. This was a highly scalable intervention that may be integrated into clinical practice as part of a longitudinal diabetes self-management program for Hispanic adults.

Negative mood is associated with sociobehavioral factors contributing to cardiovascular risk in an immigrant population.

BACKGROUND: After settling in the United States (US), immigrants often accumulate obesity and cardiovascular risk factors. As mood is often associated with health behaviors in the US population, mood may be an important mediating factor in immigrant populations. METHODS: The Healthy Immigrant Community (HIC) study, set in southeast Minnesota, enrolled 475 adult participants in a weight loss intervention designed to reduce cardiovascular risk. Baseline questionnaires assessed mood, nutrition, physical activity, self-efficacy for healthy eating and physical activity, social support, and cohesion. A single-item mood rating of poor or fair was considered "negative", while ratings of good, very good, or excellent were considered "positive". RESULTS: Hispanic/Latino (n = 268) and Somali (n = 181) adults enrolled in HIC completed baseline measures and were included in this analysis. Participants endorsing negative mood compared to positive mood had lower healthy eating scores (p = 0.02), lower physical activity levels (p = 0.03), lower confidence in eating a healthy diet (p = 0.001), and felt less of a sense of belonging to their community (p = 0.01). Those endorsing negative mood reported receiving less social support to eat healthy (p = < 0.001) and be physically active (p = 0.01). They also accessed community resources for healthy eating (p = 0.001) and physical activity (p = < 0.01) less frequently than participants endorsing positive mood. CONCLUSIONS: On self-report, negative mood was associated with less healthy nutrition, lower confidence in eating healthy, sedentary lifestyle, and perceived lack of belonging to the community. Integrating mood management and self-efficacy strategies may enhance the effectiveness of lifestyle interventions to reduce obesity and cardiovascular risk among immigrants who report negative mood.

Negative Mood is Associated with Sociobehavioral Factors Contributing to Cardiovascular Risk in an Immigrant Population.

Background: Immigrants to the United States, on average, accumulate cardiovascular risk after resettlement, including obesity. There is a need to co-create interventions to address these disparities, and mood may be an important mediating factor. Methods: The Healthy Immigrant Community (HIC) study, set in southeast Minnesota, enrolled 475 adult participants in a weight loss intervention to reduce cardiovascular risk. Baseline questionnaires assessed mood, nutrition, physical activity, self-efficacy for healthy eating and physical activity, social support, and cohesion. A single-item mood rating of poor or fair was considered "negative", while ratings of good, very good, or excellent were considered "positive". Results: A total of 449 HIC participants (268 Hispanic/Latino and 181 Somali) with complete baseline measures and were included in this analysis. Participants endorsing negative mood compared to those endorsing positive mood had lower scores for healthy eating (p = 0.02) and physical activity levels (p = 0.03), lower confidence in eating a healthy diet (p = 0.001), and felt less of a sense of belonging to their community (p = 0.01). Those endorsing negative mood also reported receiving less social support from their family and friends to eat healthy (p = < 0.001) and be physically active (p = 0.01), and less often accessed community resources for healthy eating (p = 0.001) and physical activity (p = < 0.01) compared to participants reporting positive mood. Conclusions: Negative mood was associated with less healthy nutrition, lower confidence in eating healthy, sedentary lifestyle, and perceived lack of belonging to the community. Integrating mood management and self-efficacy strategies may enhance the effectiveness of lifestyle interventions among immigrants who report negative mood.

Healthy immigrant community study protocol: A randomized controlled trial of a social network intervention for cardiovascular risk reduction among Hispanic and Somali adults.

BACKGROUND: Immigrants to the United States face structural barriers that contribute to rising cardiovascular risk factors and obesity after immigration. This manuscript describes the development of the Healthy Immigrant Community protocol and baseline measures for a stepped wedge cluster randomized trial to test the effectiveness of a social network intervention for cardiovascular risk reduction among two immigrant populations. METHODS: We developed a social network-informed, community-based, participatory research-derived health promotion intervention with Hispanic and Somali immigrant communities in Minnesota consisting of mentoring, educational and motivational sessions, group activities, and a community toolkit for healthy weight loss delivered by culturally concordant health promoters (HPs) to their social networks. Using a stepped wedge cluster randomized design, social network-based groups were randomly assigned to receive the intervention either immediately or after a delay of one year. Outcomes, measured at baseline, 6 months, 12 months, and 24 months, were derived from the American Heart Association's "Life's Simple 7": BMI and waist circumference, blood pressure, fasting blood glucose, total cholesterol, physical activity level, and dietary quality. RESULTS: A total of 51 HPs were enrolled and randomized (29 Hispanic; 22 Somali). There were 475 participants enrolled in the study, representing a mean social network group size of 8 (range, 5-12). The mean BMI of the sample (32.2) was in the "obese" range. CONCLUSION: Processes and products from this Healthy Immigrant Community protocol are relevant to other communities seeking to reduce cardiovascular risk factors and negative health behaviors among immigrant populations by leveraging the influence of their social networks.
