Background: Because medication adherence is linked to better diabetes outcomes, numerous interventions have aimed to improve adherence. However, suboptimal adherence persists and necessitate continued research into intervention strategies. This study evaluated the effectiveness of an intervention that combined storytelling and peer support to improve medication adherence and health outcomes in adults with diabetes., Methods: Living Well with Diabetes was a cluster randomized controlled trial. Intervention participants received a six-month, 11-session peer-delivered behavioral diabetes self-care program over the phone. Control participants received a self-paced general health program. Outcomes were changes in medication adherence and physiologic measures (hemoglobin A1c, systolic blood pressure, low-density lipoprotein cholesterol, body mass index)., Results: Of the 403 participants with follow-up data, mean age was 57 (±SD 11), 78% were female, 91% were African American, 56.4% had high school education or less, and 70% had an annual income of < $20,000. At follow-up, compared to controls, intervention participants had greater improvement in medication adherence (β = -0.25 [95% CI -0.35, -0.15]). Physiologic measures did not change significantly in either group. Intervention participants had significant improvements in beliefs about the necessity of medications (β = 0.87 [95% CI 0.27, 1.47]) concerns about the negative effects of medication (β = -0.91 [95% CI -1.35, -0.47]), and beliefs that medications are harmful (β = -0.50 [95% CI -0.89, -0.10]). In addition, medication use self-efficacy significantly improved in intervention participants (β = 1.0 [95% CI 0.23, 1.76]). 473 individuals were enrolled in the study and randomized., Discussion: Living Well intervention resulted in improved medication adherence, medication beliefs, and medication use self-efficacy but not improved risk factor levels., (Copyright © 2021 Elsevier Inc.

Objective: Comorbid depression is associated with increased health care utilization and cost. We examined the effects of peer support on acute care (AC) and hospital utilization in individuals with diabetes with or without depressive symptoms., Research Design and Methods: This was a cluster-randomized controlled trial conducted in 2010-2012, with the clusters being practices and their surrounding communities. Adults with type 2 diabetes who wanted help with self-management were eligible to participate. Those without a doctor, with limited life expectancy, with plans to move within the next year, and with an unwillingness to work with a peer advisor were excluded. Intervention participants received 1 year of peer support. Control participants received usual care. The Patient Health Questionnaire (PHQ-8) (range 0-24; 5 indicates mild and 10 indicates moderate depressive symptoms) assessed depressive symptoms. AC and hospital utilization were measured by self-report. Data were collected at baseline, 6 months, and 12 months. Quasi-Poisson regression using generalized estimating equations examined differences in utilization per year attributable to the intervention for those with and without mild depressive symptoms (and separately, moderate depressive symptoms), controlling for imbalance across treatment arms., Results: At baseline, half of the sample reported mild depressive symptoms (52% intervention and 48% control, P = 0.37), a quarter reported moderate depressive symptoms (25% intervention and 26% control, P = 1.0), and there were no significant differences in utilization. A total of 168 intervention (six clusters) and 187 control (five clusters) participants had follow-up data. In individuals with mild depressive symptoms, the incident rate ratio (IRR) for hospitalization among intervention compared with control was 0.26 (95% CI 0.08-0.84) per 10 patient-years. The IRR for AC was 0.55 (95% CI 0.28-1.07) per 10 person-years. Findings were similar for individuals with moderate depressive symptoms., Conclusions: Peer support lowered AC visits and hospitalizations for individuals with depressive symptoms but not for those without depressive symptoms; these findings can guide resource allocation for population health management., (© 2018 by the American Diabetes Association.)

Aims: To assess the relationship between pain and HbA(1c) levels in a predominantly black population with diabetes, and to determine whether self-management behaviours (exercise and diet) and symptoms of depression mediate this relationship., Methods: We analysed cross-sectional data from 417 community-dwelling individuals with diabetes in rural Alabama, USA. Binary logistic regression was used to analyse the relationship between pain and HbA(1c) levels, defined as relatively good [≤ 64 mmol/mol (≤ 8.0%)] and relatively poor [> 64 mmol/mol (> 8.0%)], after adjusting for sociodemographics, insulin use, medication count, cigarette smoking history and body mass index (BMI). We examined the mediating roles of exercise, diet, and symptoms of depression using bootstrapping., Results: Participants were primarily black (86.6%), female (76.1%) and reported an annual income of ≤$20,000 (52.7%). Their mean (sd) age was 59.6 (12.8) years. The majority of the participants reported moderate to extreme pain (71.5%). Participants reporting pain were more than twice as likely to have HbA(1c) levels > 64 mmol/mol (8.0%) in the fully adjusted model (odds ratio 2.33 [95% CI 1.28-4.24]; P < 0.05). Diet significantly mediated the relationship between pain and HbA(1c) control (β = 0.06; 95% CI: 0.01-0.17), but only in the unadjusted model. Exercise and symptoms of depression were not significant mediators., Conclusions: A significant independent relationship between pain and HbA(1c) control was found in this mainly black population, which was not explained by self-management behaviours or symptoms of depression. Future research is needed to delineate the mechanism by which pain influences HbA(1c) control, especially among black people with diabetes on low incomes., (© 2013 The Authors.

We are conducting a community-based cluster-randomized trial in rural Alabama, testing a peer-support intervention designed to improve diabetes self-care behaviors. We describe recruitment and data collection approaches used, focusing on strategies that created community partnerships and facilitated recruitment in underserved, rural, largely minority communities. Key recruitment and data collection strategies included early community engagement; pilot testing of procedures; inclusion of community members as study team members, recruiters, and data collectors; data collection at community venues to minimize participant travel requirements; and provision of a multi-disciplinary diabetes education program to both intervention and control participants. A total of 424 participants were recruited and enrolled (400 targeted). Of the 759 referrals received, 78.9% (n=599) successfully completed telephone screening. Of these, 78.8% (n=472) were eligible and scheduled for a local enrollment day, and 81.4% (n=384) attended and enrolled in the study. In addition, community members who walked in and expressed interest were screened, and 40 eligible and willing individuals were consented and enrolled. We exceeded recruitment goals in underserved, rural communities in Alabama. This success was due in large part to community partnerships that facilitated community involvement on several levels: engaging the community early in study proposal and design; hiring community members to fill various capacities as research team members, recruiters, and data collectors; conducting data collection within communities; and collecting additional contact information to maintain communication. Providing diabetes education to all participants, including intervention and control, helped ensure that everyone stood to benefit and likely enhanced overall participation., (Copyright © 2012 Elsevier Inc.
