The Science of Diabetes Self-Management and Care

Purpose

The purpose of this review is to provide educators with the knowledge and tools to utilize plant-based nutrition education as an intervention for type 2 diabetes. Scientific support for the efficacy, acceptability, and nutritional adequacy of a plant-based diet for people with type 2 diabetes is presented, and practical considerations such as medication adjustment and risk of hypoglycemia are reviewed.

Conclusions

Plant-based meal planning is an acceptable and effective strategy that educators can use to improve diabetes management and reduce risk of complications. Studies show that dietary changes that are effective for reducing cardiac risk may also be helpful for management of type 2 diabetes. A low-fat, plant-based diet reduces body weight and improves glycemic control, and has been shown to be remarkably well accepted by patients.

Real-time continuous glucose monitoring (RT-CGM) provides new dimension to diabetes management. However, there are many challenges to using RT-CGM successfully. This article aims to present how RT-CGM is integrated into diabetes clinical practice at the Yale Children’s Diabetes Program (YCDP). The authors provide factors to consider when choosing one of the commercially available RT-CGM systems and a discussion of key strategies for successful use of RT-CGM for families. Careful training and troubleshooting strategies will ensure the most positive experience possible for a family using RT-CGM.

Purpose

The purpose of this study was to evaluate the effects of restless legs syndrome (RLS) on quality of life (QoL), anxiety, and depression in people with type 2 diabetes.

Methods

One hundred twenty-four patients with type 2 diabetes were enrolled in this study. RLS was diagnosed by a neurologist masked on psychological evaluation. Data on severity, frequency, and duration of the sleep disorder were collected. The Italian version of the SF-36 was used to assess QoL. Psychological status was investigated by a neuropsychologist masked on RLS diagnosis. Patients with a diagnosis of generalized anxiety disorder (GAD) and major depressive disorder (MDD) were considered affected by anxiety and depression, respectively. A modified version of the Hamilton Anxiety and Depression Rating Scales (HARS and HDRS) was also administered.

Results

RLS was an independent predictor for several mental domains of the SF-36 and for the mental component summary. Multivariate analysis showed that RLS was an independent predictor of anxiety and depression. RLS severity correlated with HARS and HDRS scores, whereas frequency per week of RLS had a significant correlation only with HARS score.

Conclusions

Among individuals with diabetes, RLS can impair mental health, increasing the risk for anxiety and depression. Since RLS consequences on nocturnal rest and psychological status may impair glycemic control in this population, diabetologists and diabetes educators should investigate for the presence of RLS in their patients and treat them.

Purpose

The purpose of this study was to test the efficacy of a social support intervention with parents of children <13 years old newly diagnosed with type 1 diabetes mellitus (T1DM).

Methods

For this randomized, controlled clinical trial, 10 parent mentors of children diagnosed with T1DM ≥1 year and 60 parent participants were recruited from 2 pediatric diabetes centers. Mentors were trained to provide social support (home visits and phone calls) for 12 months to families in the experimental arm (32 mothers). Control group parents (28 mothers) received the phone number of an experienced parent (not trained to give social support) to call as needed.

Findings

Mothers in the experimental and control arms differed at baseline only in birth order of the child with T1DM. The 2 groups did not differ significantly at 3, 6, or 12 months in parent concern, confidence, worry, impact on the family, or perceived social support. Mothers in the experimental arm identified the parent mentor as someone they would seek for advice and issues regarding growth and development, sleep, eating habits, and identification of community agencies. Parent mentors consistently referred mothers to health care providers for advice on medications and treatments but helped them incorporate this advice into day-to-day management.

Conclusion

Mothers in the experimental arm valued the mentors’ help in adjusting to the diagnosis, but this value was not measured by the study instruments. Focus group research is under way to clarify the concept of parent mentor social support and to develop a social support measurement tool.

Purpose

Adequate training and support are critical for community health workers (promotoras de salud in Spanish) to work effectively. Current literature on promotora training is limited by a focus on promotoras’ knowledge and satisfaction immediately after training. The relevance of training to subsequent work performance and the need for ongoing training are rarely addressed. This article describes the training and evaluation components of a promotora intervention focused on diabetes self-management.

Training Methods

Project MATCH (the Mexican American Trial of Community Health Workers) is a clinical trial designed to test the effectiveness of an intensive, promotora-based intervention to improve disease self-management for Mexican Americans with diabetes. The MATCH investigators designed a multicomponent promotora training program that provided both initial and ongoing training. The investigators used multiple methods to determine promotoras’ knowledge levels, initial competency in intervention delivery, and changes in this competency over time.

Evaluation Methods and Results

The evaluation results show that although the initial training provided a solid knowledge and skills base for the promotoras, the ongoing training was critical in helping them deal with both intervention-related and personal challenges.

Conclusions

The experiences of the MATCH study suggest that in addition to strong initial training, promotora interventions benefit from ongoing training and evaluation to ensure success.

Purpose

The purpose of this study was to assess whether the VA-MEDIC (Veterans Affairs Multi-disciplinary Education and Diabetes Intervention for Cardiac risk reduction), a pharmacist-led group medical visit program, could improve achievement of target goals in hypertension, hyperglycemia, hyperlipidemia, and tobacco use in patients with type 2 diabetes compared to usual care.

Methods

This was a randomized controlled trial of VA-MEDIC intervention in addition to usual care versus usual care alone in diabetic patients to reduce cardiac risk factors. VA-MEDIC consisted of a 40- to 60-minute educational component by nurse, nutritionist, physical therapist, or pharmacist followed by pharmacist-led behavioral and pharmacological interventions over 4 weekly sessions.

Measures

The attainment of target goals in hemoglobin A1C (A1C), blood pressure, fasting lipids, and tobacco use recommended by the American Diabetes Association.

Results

Of 118 participants, 109 completed the study. VA-MEDIC (n = 58) participants were younger and had greater tobacco use at baseline than usual care but were similar in other cardiovascular risk factors. After 4 months, a greater proportion of VA-MEDIC participants versus controls achieved an A1C of less than 7% and a systolic blood pressure less than 130 mm Hg. No significant change was found in lipid control or tobacco use between the 2 study arms.

Conclusion

Pharmacist-led group medical visits are feasible and efficacious for improving cardiac risk factors.

Purpose

This purpose of this report is to describe a successful telephone intervention to increase the rate of diabetic retinopathy screening, its implementation with English and Spanish speakers, and the characteristics of those who benefited most from the intervention.

Methods

Participants in the telephone group (N = 305) received a tailored intervention from trained health educators who were ethnically diverse and representative of the community. The main outcome for the randomized controlled study was documented receipt of a dilated fundus examination (DFE) within the 6-month study window. Exploratory analyses focused on examining the factors that contribute to receiving a DFE within 6 months for participants in the tailored telephone intervention using Pearson χ2 and logistic regression analysis.

Results

Participants in the telephone intervention who did not receive a DFE had significantly more documented steps in the behavioral process than those who did receive a DFE, and ethnic concordance of the health educator was not significantly associated with a positive outcome in the DFE group. There was a negative association between the time spent building rapport and receipt of DFE. As time spent engaging in educational activities by telephone increased, the likelihood of receiving a DFE increased.

Conclusions

Although the telephone intervention was highly successful compared with the print intervention, these process results demonstrate the difficulties and challenges of conducting a tailored telephone intervention to improve rates of screening in an underserved, diverse urban community.

Purpose

The purpose of this study was to evaluate the impact of an innovative intervention that utilized a certified medical assistant with specific diabetes training to work with a multidisciplinary diabetes care team to help provide basic diabetes education and self-care support in low-income minority populations with type 2 diabetes.

Methods

Enrolled participants were randomized to either the medical assistant coaching (MAC) group (N = 25) or the treatment as usual (TAU) group (N = 25). Deidentified data was obtained on a matched no contact control (NCC) group (N = 50).

Results

Analysis of covariance (ANCOVA) comparisons revealed no significant differences between the 3 groups on A1C, but a trend was observed. A1Cs decreased across time for the MAC group, while increasing for the TAU and NCC groups. ANCOVA comparisons also indicated that the MAC group experienced significantly greater increases in perceived empowerment and a larger, although non-significant, reduction in perceived diabetes related problems than the TAU group.

Conclusions

This randomized controlled pilot study suggests that the inclusion of a medical assistant self-care coach as part of the diabetes care team holds promise in improving outcomes and should be further examined in a large-scale study.

Purpose

The purpose of this study was to evaluate the effectiveness of a self-help physical activity program for persons with type 2 diabetes. Effectiveness was measured by cardiovascular indicators, hemoglobin A1C, anthropometric indicators, and activity levels.

Methods

This intervention study included 53 individuals with type 2 diabetes. Participants were randomly assigned. Participants in the intervention group attended the usual Diabetes Self-Management Education Program (DSMEP) and received a copy of the book, Manpo-kei; a concise handout summarizing the key points of Manpo-kei; and a pedometer. Participants not assigned to the intervention attended the usual DSMEP only. Data collection was completed at the beginning of the study and 3 months later using a lifestyle and diabetes questionnaire, a physical activity questionnaire, and cardiovascular and anthropometric measures.

Results

Those who participated in the intervention demonstrated a significant decrease in hemoglobin A1C, weight, and body fat. In addition, they increased their number of daily steps as measured by the pedometer. The control group also demonstrated a significant decrease in hemoglobin A1C and weight. Both groups demonstrated increases in their regular weekly activity. At the end of the study period, the intervention group had a significantly lower diastolic blood pressure than the control group.

Conclusions

Pedometers can be a helpful strategy to motivate persons with diabetes to increase physical activity. However, it appears that attendance at DSMEP alone may be enough to increase physical activity for persons with type 2 diabetes.

Objective

To develop, implement, and evaluate a peer-led diabetes self-management support program in English and Spanish for a diverse, urban, low-income population. The program goals and objectives were to improve diabetes self-management behaviors, especially becoming more physically active, healthier eating, medication adherence, problem solving, and goal setting.

Methods

After a new training program for peers led by a certified diabetes educator (CDE) was implemented with 5 individuals, this pilot evaluation study was conducted in 2 community settings in the East and South Bronx. Seventeen adults with diabetes participated in the new peer-led 5-session program. Survey data were collected pre- and postintervention on diabetes self-care activities, quality of well-being, and number of steps using a pedometer.

Results

This pilot study established the acceptance and feasibility of both the peer training program and the community-based, peer-led program for underserved, minority adults with diabetes. Significant improvements were found in several physical activity and nutrition activities, with a modest improvement in well-being. Feedback from both peer facilitators and participants indicated that a longer program, but with the same educational materials, was desirable.

Conclusions

To reduce health disparities in urban communities, it is essential to continue program evaluation of the critical elements of peer-led programs for multiethnic adults with diabetes to promote self-management support in a cost-effective and culturally appropriate manner.

Practice Implications

A diabetes self-management support program can be successfully implemented in the community by peers, within a model including remote supervision by a CDE.
