A demonstration of peer support for Ugandan adults with type 2 diabetes

The effects of diabetes clubs on peer-support, disclosure of diabetes status, and sources of information regarding diabetes management: results of a pilot-intervention in rural Vietnam

OBJECTIVES

To measure the effects of diabetes clubs on peer support, disclosure of diabetes status, and the source of information regarding the management of diabetes among persons living with type-2 diabetes (T2D) in rural Vietnam.

STUDY DESIGN

A pre- and post-pilot intervention study was carried out in Thai Binh Province, Vietnam (n = 222).

RESULTS

Post-intervention, 57.7 % reported using experiences shared by other persons with T2D during the diabetes club sessions. Compared to pre-intervention, there was an increase in the proportion of persons with T2D who disclosed their diabetes status to friends and/or community members (an increase of 15.3 and 13.8 percentage points, respectively). The proportion of persons who reported gathering their own information regarding diabetes management without any support from others decreased from 15.7 % to 6.3 %. Those who reported a relative inside their home or a relative outside their household as their primary source of T2D-relevant information increased from 10.8 % to 18.6 % and from 2.7 % to 9.5 %, respectively. Persons who mentioned that they did not have a need for further support for their diabetes care increased from 18.5 % to 32.0 %. Specific support regarding diabetes-related knowledge received from family members, friends, and/or community members increased from 27.5 % to 62.2 % CONCLUSIONS: These findings suggest a promising potential for the implementation of diabetes clubs to enhance diabetes-relevant knowledge and the quality of self-management among persons living with T2D diabetes in rural areas of Vietnam.

Peer Support for Type 2 Diabetes Management in Low- and Middle-Income Countries (LMICs): A Scoping Review

Background

Although there is evidence of peer support in high-income countries, the use of peer support as an intervention for cardiometabolic disease management, including type 2 diabetes (T2DM), in low- and middle-income countries (LMICs), is unclear.

Methods

A scoping review methodology was used to search the databases MEDLINE, Embase, Emcare, PsycINFO, LILACS, CDSR, and CENTRAL.

Results

Twenty-eight studies were included in this scoping review. Of these, 67% were developed in Asia, 22% in Africa, and 11% in the Americas. The definition of peer support varied; however, peer support offered a social and emotional dimension to help individuals cope with negative emotions and barriers while promoting disease management.

Conclusions

Findings from this scopingreview highlight a lack of consistency in defining peer support as a component of CMD management in LMICs. A clear definition of peer support and ongoing program evaluation is recommended for future research.

The role of social support and the built environment on diabetes management among structurally exposed populations in three regions in Ghana

Sub-Saharan Africa is undergoing an epidemiological transition driven by rapid, unprecedented demographic, socio-cultural, and economic transitions. These transitions are driving increases in the risk and prevalence of diabetes and other non-communicable diseases (NCDs). As NCDs rise, several attempts have been made to understand the individual level factors that increase NCDs risks, knowledge, and attitudes around specific NCDs as well as how people live and manage NCDs. While these studies are important, and enhance knowledge on chronic diseases, little attention has been given to the role of social and cultural environment in managing chronic NCDs in underserved settings. Using purposive sampling among persons living with Diabetes Mellitus (PLWD) and participating in diabetes programs from regional and municipal hospitals in the three underserved regions in Ghana (n = 522), we assessed diabetes management and supportive care needs of PLWDs using linear latent and mixed models (gllamm) with binomial and a logit(log) link function. The result indicates that PLWDs with strong perceived social support (OR = 2.27, p ≤ 0.05) were more likely to report good diabetes management compared to PLWDs with weak perceived social support. The built environment, living with other health conditions, household wealth, ethnicity and age were associated with diabetes management. Overall, the study contributes to wider discussions on the role changing built and socio-cultural environments in the rise of diet-related diseases and their management as many Low- and Middle-Income Countries (LMICs) experience rapid epidemiological and nutrition transitions.

Gammeltoft T, Christian Bygbjerg I, W. Meyrowitsch D, Søndergaard J. Pre-/-post-analyses of a feasibility study of a peer-based club intervention among people living with type 2 diabetes in Vietnam's rural communities

OBJECTIVES

Insufficient self-management is a significant barrier for people with type 2 diabetes (T2D) to achieve glycemic control and consequently reduce the risk of acute and long-term diabetes complications, negatively affecting their quality of life and increasing their risk of diabetes-related death. This pre-post study aimed to evaluate whether a peer-based club intervention might reduce glycated hemoglobin from baseline to post-intervention and enhance self-management among people living with T2D in two rural communities in Vietnam.

METHODS

A pre-post study was implemented with 222 adults with T2D residing in two rural communities in Vietnam. We used a structured questionnaire, clinical examination, and glycated hemoglobin to evaluate the possible effects of a diabetes club intervention by comparing Glycated Hemoglobin (HbA1c), Body Mass Index (BMI), Blood Pressure (BP), and diabetes-related self-management behaviors at baseline and post-intervention. The data were analyzed using SPSS 20, applying two related sample tests (Wilcoxon and McNemar test) and a paired-sample t-test at a significance level of less than 0.05.

RESULTS

The findings indicated that after implementation of the intervention, there were no significant statistical differences when comparing pre-and post-intervention levels of the primary outcome HbA1c, but some components of diabetes self-management showed statistically significant improvement.

CONCLUSIONS

After the peer support intervention in a Vietnamese rural community, there was no significant reduction in the primary outcome proportion of patients having an HbA1c less than 7%, but foot care knowledge and practice had improved.

The effect of mHealth program on behavior modification and health outcomes among patients with diabetes: A randomized controlled trial study

Background

Mobile health presents a promising alternative in the digital era. Mobile health apps (mHealth), when combined with the concept of self-management, are considered one of the methods for incorporating technology-based interventions into the healthcare system.

Objective

This study aimed to determine the effect of mHealth (specifically, the Diabetic Care App) on foot care behavior, dietary behavior, foot condition, and fasting blood glucose levels among patients with uncontrolled diabetes mellitus.

Methods

A single randomized controlled trial was conducted at a government-run primary clinic in Northern Malaysia, involving 58 patients with uncontrolled diabetes who were assigned to two groups. The intervention group received the Diabetic Care App, attended a 2-hour face-to-face session, and was included in a WhatsApp group, while the control group received standard care. Relevant assessments were conducted for both groups in Week 1 and Week 5. The study was conducted from February 2020 to November 2020, and parametric and non-parametric statistics were used for data analysis.

Results

Pretest-posttest comparisons in both groups revealed significant findings for foot care behavior (p <0.01), dietary behavior (p <0.01), and foot condition (p <0.01), except for fasting blood glucose levels. In inter-group comparisons, a significant difference was observed only in foot care behavior (p <0.01) and dietary behavior (p <0.01).

Conclusion

The results indicate that technology-based interventions are beneficial for modifying behavior, specifically in terms of foot care and dietary behavior, in this study. The study highlights the applicability of mHealth for nurses in patient education and self-management of chronic conditions. Future research should explore app utilization among patients with chronic conditions.

Peer support and social networking interventions in diabetes self-management in Kenya and Uganda: A scoping review

Background

Diabetes mellitus is a growing worldwide health challenge especially in sub-Saharan Africa. While the use and effectiveness of diabetes self-management interventions is well documented in high-income countries, little information exists in sub-Saharan Africa. Therefore, this study attempted to synthesize information in the literature on the use and efficacy of peer support and social networking in diabetes self-management in Kenya and Uganda.

Objective

The purpose of this scoping review is to summarize research on the extent of use and efficacy of peer support and social networking interventions in diabetes self-management in Kenya and Uganda.

Design

We searched PubMed, ScienceDirect and Cochrane Library databases for articles reporting peer support and social networking interventions in Kenya and Uganda published in English between 2000 and September 2021. Key words encapsulated three major themes: peer support, social networking and self-management. Hand searches were also conducted to select eligible papers. Data was extracted using a form prepared and piloted in line with PRISMA-ScR guidelines.

Results

Thirteen peer reviewed articles were selected for analysis. Eleven studies reported peer support interventions while two focused on social networks in diabetes self-management. Peer support and social networking interventions incorporated microfinance and group medical visits, diabetes self-management education, telephone support and Medication Adherence Clubs. Most interventions were delivered by multidisciplinary teams comprising nurses and other professionals, peer educators, peer leaders and community health workers. Most interventions were effective and led to improvements in HbA1c and blood pressure, eating behaviors and physical activity and social support.

Conclusions

The limited studies available show that peer support and social networking interventions have mixed results on health and other outcomes. Importantly, most studies reported significant improvements in clinical outcomes. Further research is needed on the nature and mechanisms through which peer support and social network characteristics affect health outcomes.

Developing, validating, and pre-testing of a diabetic care self-management mobile health application: A technology-based intervention for patients with diabetes in Malaysia

Background

Technology-based intervention showed a promising approach to health promotion strategies. There had been limited knowledge of the existing program for technology-based intervention in promoting foot care and dietary behavior modification. Thus, a mobile app was developed as an alternative strategy for promoting foot care and dietary behavior modification.

Objective

This paper aims to elaborate on the process of developing, validating, and examining the Diabetic Care Self-Management Mobile Health Application (Diabetic Care).

Methods

There are two phases conducted. The first phase is the process of developing and validating Diabetic Care. Intervention Mapping (IM) Framework was used to guide the process of developing Diabetic Care, while in assessing validity, guidance from Kassam-Adams et al. was used. A team of experts was appointed to validate the mobile app developed. Next, the usability of Diabetic Care was conducted among ten conveniently chosen patients with diabetes in a governmental primary care clinic.

Results

The process of developing Diabetic Care was clearly explained. The Diabetic Care app showed a good I-CVI score (1.00) and general CVI score (1.00) after the expert team assessed. During the trial, two drawbacks were identified and explored to find solutions.

Conclusion

The Diabetic Care app is proven appropriate to be employed in the study. Even though there were two drawbacks encountered, however, possible solutions were able to be explored in addressing the issues. Further research should be conducted to examine the effectiveness of this mobile app in modifying foot care behavior and dietary behavior. Hence, it will assist in the translation of advanced technology in nursing care.

Factors Influencing the Implementation of Remote Delivery Strategies for Non-Communicable Disease Care in Low- and Middle-Income Countries: A Narrative Review

Objectives: The COVID-19 pandemic has disrupted health care for non-communicable diseases (NCDs) and necessitated strategies to minimize contact with facilities. We aimed to examine factors influencing implementation of remote (non-facility-based) delivery approaches for people with hypertension and/or diabetes in low- and middle-income countries (LMICs), to inform NCD care delivery during health service disruption, including humanitarian crises.

Methods: Our narrative review used a hermeneutic and purposive approach, including primary studies conducted in LMICs, which assessed implementation factors influencing remote NCD care delivery. Results were analyzed using the Consolidated Framework for Implementation Research.

Results: Twenty-eight included studies revealed the strong influence of both internal organizational and broader contextual factors, such as community health worker policies or technological environment. Addressing patients’ specific characteristics, needs and resources was important for implementation success.

Conclusion: This review highlighted the multiple, complex, interdependent factors influencing implementation of remote NCD care in LMICs. Our findings may inform actors designing NCD care delivery in contexts where facility-based access is challenging. Implementation research is needed to evaluate context-adapted e-Health, community-based, and simplified clinical management strategies to facilitate remote NCD care.

Predictors and Effects of Participation in Peer Support: A Prospective Structural Equation Modeling Analysis

BACKGROUND

Peer support provides varied health benefits, but how it achieves these benefits is not well understood.

PURPOSE

Examine a) predictors of participation in peer support interventions for diabetes management, and b) relationship between participation and glycemic control.

METHODS

Seven peer support interventions funded through Peers for Progress provided pre/post data on 1,746 participants' glycemic control (hemoglobin A1c), contacts with peer supporters as an indicator of participation, health literacy, availability/satisfaction with support for diabetes management from family and clinical team, quality of life (EQ-Index), diabetes distress, depression (PHQ-8), BMI, gender, age, education, and years with diabetes.

RESULTS

Structural equation modeling indicated a) lower levels of available support for diabetes management, higher depression scores, and older age predicted more contacts with peer supporters, and b) more contacts predicted lower levels of final HbA1c as did lower baseline levels of BMI and diabetes distress and fewer years living with diabetes. Parallel effects of contacts on HbA1c, although not statistically significant, were observed among those with baseline HbA1c values > 7.5% or > 9%. Additionally, no, low, moderate, and high contacts showed a significant linear, dose-response relationship with final HbA1c. Baseline and covariate-adjusted, final HbA1c was 8.18% versus 7.86% for those with no versus high contacts.

CONCLUSIONS

Peer support reached/benefitted those at greater disadvantage. Less social support for dealing with diabetes and higher PHQ-8 scores predicted greater participation in peer support. Participation in turn predicted lower HbA1c across levels of baseline HbA1c, and in a dose-response relationship across levels of participation.

Prevention and management of type 2 diabetes mellitus in Uganda and South Africa: Findings from the SMART2D pragmatic implementation trial

Health systems in many low- and middle-income countries are struggling to manage type 2 diabetes (T2D). Management of glycaemia via well-organized care can reduce T2D incidence, and associated morbidity and mortality. The primary aim of this study was to evaluate the effectiveness of facility plus community care interventions (integrated care), compared to facility only care interventions (facility care) towards improvement of T2D outcomes in Uganda and South Africa. A pragmatic cluster randomized trial design was used to compare outcomes among participants with T2D and those at high risk. The trial had two study arms; the integrated care arm, and the facility care arm; and in Uganda only, an additional usual care arm. Participants were enrolled at nine primary health facilities in Uganda, and two in South Africa. Participants were adults aged 30 to 75 years, and followed for up to 12 months. Primary outcomes were glycaemic control among participants with T2D, and reduction in HbA1c > = 3 mmol/mol among participants at high risk. Secondary outcomes were retention into care and incident T2D. Adjusted analysis revealed significantly higher retention into care comparing integrated care and facility care versus usual care in Uganda and integrated care versus facility care in South Africa. The effect was particularly high among participants at high risk in Uganda with an incident rate ratio of 2.46 [1.33-4.53] for the facility care arm and 3.52 [2.13-5.80] for the integrated care arm. No improvement in glycaemic control or reduction in HbA1c was found in either country. However, considerable and unbalanced loss to follow-up compromised assessment of the intervention effect on HbA1c. Study interventions significantly improved retention into care, especially compared to usual care in Uganda. This highlights the need for adequate primary care for T2D and suggest a role for the community in T2D prevention. Trial registration number: ISRCTN11913581.

Amankwah J. Diabetes self-management education interventions in the WHO African Region: A scoping review

INTRODUCTION

Diabetes mellitus (DM) is one of the commonest chronic diseases worldwide. Self-Management Education (SME) is regarded as a critical element of treatment for all people with diabetes, as well as those at risk of developing the condition. While a great variety of diabetes self-management education (DSME) interventions are available in high-income countries, limited information exists on educational programs for the prevention and management of diabetes complications in Africa. This study, therefore, aimed at synthesizing information in the literature to describe the state of the science of DSME interventions in the WHO African Region.

MATERIALS AND METHODS

The study is a scoping review, which followed the standard PRISMA guidelines for conducting and reporting scoping reviews. A systematic keyword and subject headings searches were conducted on six electronic databases (PubMed, Scopus, MEDLINE, EMBASE, PsychINFO and the Cochrane Central Register of Controlled Trials) to identify relevant English language publications on DSME from 2000 through 2020. Titles and abstracts of the search results were screened to select eligible papers for full text reading. All eligible papers were retrieved and full text screening was done by three independent reviewers to select studies for inclusion in the final analysis.

RESULTS

Nineteen studies were included in the review. The interventions identified were individually oriented, group-based, individually oriented & group-based, and information technology-based DSME programs. Outcomes of the interventions were mixed. While the majority yielded significant positive results on HbA1c, diabetes knowledge, blood pressure, blood sugar and foot care practices; few demonstrated positive outcomes on self-efficacy, BMI, physical activity; self-monitoring of blood glucose, medication adherence, smoking and alcohol consumption.

CONCLUSIONS

The limited studies available indicate that DSME interventions in the WHO African Region have mixed effects on patient behaviors and health outcomes. That notwithstanding, the majority of the interventions demonstrated statistically significant positive effects on HbA1c, the main outcome measure in most DSME intervention studies.

Evaluation of diabetic peer support in Malawi

Background

Type 2 diabetes is a major health concern worldwide and requires urgent attention from health care providers and policy makers. Due to shortage of health care workers in low-income countries, peer support programs have been viewed as a viable option in management of diabetes and have shown to be effective in sub-Saharan Africa.

Objective

The aim of this study is to assess and evaluate the Kamuzu Central Hospital (KCH) diabetic peer support program's (DPSP) impact 4 years after its establishment by assessing knowledge, self-efficacy and behaviours of DPSP members compared to non-members.

Methodology

This is a cross-sectional study done among diabetic patients attending clinics between 12th August and 25th September 2018 at KCH. Self and interviewer-administered questionnaires (designed based on validated survey instruments) were used. The participants (n=176) were recruited consecutively after consenting.

Results

Results showed DPSP members were more knowledgeable regarding the effects of skipping meals and sweet juice on blood glucose and conditions not associated with diabetes. In terms of self-efficacy and behaviour changes, DPSP members believe that they are more able to correct hypoglycaemia, to communicate their concerns to health workers and to perform daily foot exam compared to non-members.

Conclusion

The KCH (Lilongwe) Diabetes Peer Support program has positively impacted its members and should be scaled up to engage all diabetic patients in Malawi. Ongoing training for peer supporters is necessary to update and reinforce management, knowledge and skills, and to ensure fidelity in program implementation.

Self-management in face-to-face peer support for adults with type 2 diabetes living in low- or middle-income countries: a systematic review

Background

Peer support has been recognised as a promising strategy to improve self-management in patients living with chronic conditions, such as Type 2 diabetes (T2D). The purpose of the review was to synthesise the best available evidence on face-to-face peer support models for adults with T2D in low and middle-income countries (LMICs).

Methods

We searched Medline, Cumulative Index to Nursing and Allied Health, Literature Academic Search Ultimate, PsycINFO, CAB Abstracts, Health Source: Nursing/Academic Edition, SPORTDiscus, Africa-Wide Information, MasterFILE Premier, SocINDEX, ERIC, PsycARTICLES, Open Dissertations, Communication & Mass Media Complete, Health Source-Consumer Edition and Google Scholar for the period January 2000 to December 2017. Reference list checking and contact with authors were additional sources of data. Screening of papers, critical appraisal and data extraction were carried out independently by at least two reviewers.

Results

From 3092 abstracts retrieved from database searches, data was extracted from 12 papers. There was no consistency in design, setting, outcomes or measurement instruments amongst the papers. The papers were associated with improvements in various clinical and behavioural outcomes. Diabetic patients and community health workers (CHWs) were identified as two common face-to-face peer support models. The recruitment and selection of diabetic patients as peer supporters focused on patients from the community, with good glycaemic control and/or leadership skills, who were recommended by healthcare professionals. Recruitment of CHWs as peer supporters was done from an existing infrastructure of CHWs in the community and, thus, selection criteria were poorly described. The training of peer supporters featured as an important component, highlighting who provided training and the duration and content covered in training. Motivational interviewing was the most common theory basis of training used in the peer support interventions. Face-to-face, group and/or individual-based peer support was often supplemented by other peer support methods. The supervision of peer supporters was generally poorly described.

Conclusions

The comprehensive synthesis of the best available evidence has led to new insights regarding face-to-face peer support as a self-management strategy for patients with T2D in LMICs. Face-to-face peer support may be implemented in innovative ways to improve the quality of life of patients with T2D.

Feasibility of a cluster randomized controlled trial on the effectiveness of peer-led health education interventions to increase uptake of retinal examination for diabetic retinopathy in Kirinyaga, Kenya: a pilot trial

Background

People living with diabetes can reduce their risk of vision loss from diabetic retinopathy by attending screening, which enables early detection and timely treatment. The aim of this pilot trial was to assess the feasibility of a full-scale cluster randomized controlled trial of an intervention to increase uptake of retinal examination in this population, as delivered within existing community-based diabetes support groups (DSGs).

Methods

All 16 DSGs in Kirinyaga county were invited to participate in the study. The first two groups recruited took part in the pilot trial. DSG members who met the eligibility criteria were recruited before the groups that were randomized to the two arms. In the intervention group, two peer educators were trained to deliver monthly DSG-based eye health education and individual telephone reminders to attend screening. The control group continued with usual DSG practice which is monthly meetings without eye health education. The recruitment team and outcome assessors were masked to the allocation. We documented the study processes to ascertain the feasibility, acceptability, and potential effectiveness of the intervention. Feasibility was assessed in terms of clarity of study procedures, recruitment and retention rates, level of acceptability, and rates of uptake of eye examination. We set the target feasibility criteria for continuation to the main study to be recruitment of 50 participants in the trial, 80% monthly follow-up rates for individuals, and no attrition of clusters.

Results

Of the 122 DSG members who were assessed for eligibility, 104 were recruited and followed up: 51 (intervention) and 53 (control) arm. The study procedures were well understood and easy to apply. We learnt the DSG meeting days were the best opportunities for recruitment. The study had a high acceptance rate (100% for clusters, 95% for participants) and high follow-up and retention rate (100% of those recruited). All clusters and participants were analysed. We observed that the rate of incidence of eye exam was about 6 times higher in the intervention arm as compared to the control arm. No adverse unexpected events were reported in either arm.

Conclusions

The study is feasible and acceptable in the study population. The results support the development of a full-scale cluster RCT, as the success criteria for the pilot were met.

The effectiveness of peer and community health worker-led self-management support programs for improving diabetes health-related outcomes in adults in low- and-middle-income countries: a systematic review

OBJECTIVE

Community-based peer and community health worker-led diabetes self-management programs (COMP-DSMP) can benefit diabetes care, but the supporting evidence has been inadequately assessed. This systematic review explores the nature of COMP-DSMP in low- and middle-income countries' (LMIC) primary care settings and evaluates implementation strategies and diabetes-related health outcomes.

METHODS

We searched the Cochrane Library, PubMed-MEDLINE, SCOPUS, CINAHL PsycINFO Database, International Clinical Trials Registry Platform, Clinicaltrials.gov, Pan African Clinical Trials Registry (PACTR), and HINARI (Health InterNetwork Access to Research Initiative) for studies that evaluated a COMP-DSMP in adults with either type 1 or type 2 diabetes in World Bank-defined LMIC from January 2000 to December 2019. Randomised and non-randomised controlled trials with at least 3 months follow-up and reporting on a behavioural, a primary psychological, and/or a clinical outcome were included. Implementation strategies were analysed using the standardised implementation framework by Proctor et al. Heterogeneity in study designs, outcomes, the scale of measurements, and measurement times precluded meta-analysis; thus, a narrative description of studies is provided.

RESULTS

Of the 702 records identified, eleven studies with 6090 participants were included. COMP-DSMPs were inconsistently associated with improvements in clinical, behavioural, and psychological outcomes. Many of the included studies were evaluated as being of low quality, most had a substantial risk of bias, and there was a significant heterogeneity of the intervention characteristics (for example, peer definition, selection, recruitment, training and type, dose, and duration of delivered intervention), such that generalisation was not possible.

CONCLUSIONS

The level of evidence of this systematic review was considered low according to the GRADE criteria. The existing evidence however does show some improvements in outcomes. We recommend ongoing, but well-designed studies using a framework such as the MRC framework for the development and evaluation of complex interventions to inform the evidence base on the contribution of COMP-DSMP in LMIC.

Community-based interventions for prevention of Type 2 diabetes in low- and middle-income countries: a systematic review

Type 2 diabetes is an increasing burden in low- and middle-income countries (LMICs). Knowledge of effective prevention programs in LMICs is thus important. The aim of this review was to establish an overview of studies evaluating the effectiveness of community-based interventions for prevention of Type 2 diabetes in LMICs. A literature review with searches in the databases using MEDLINE in Ovid (Ovid MEDLINE® In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily, Ovid MEDLINE and Version (R); Embase; PsycINFO; Global Health; and Google Scholar) between 1 January 2000 and 31 December 2015 was conducted. Only 10 studies that met our selection criteria were included; 3 were randomized controlled trials, 2 non-randomized controlled trials and 5 were pre-and post-intervention studies. About 9 of 10 studies reported significant reduction in both the glycated hemoglobin (HbA1c) and fasting blood glucose (FBG) levels as a result of the intervention. A majority of the studies included multicomponent interventions such as education and behavioral encompassing both individual and group work, and included health education, nutrition education, nutrition counseling, exercise and promoting physical activity, psychosocial approaches and lifestyle modification. The interventions were delivered by community health workers, volunteers, social workers, community nutritionists and community nurses. Comparisons between studies, however, was not possible due to substantial heterogeneity in study design. This review contributes to the current literature on community-based interventions for prevention of Type 2 diabetes in LMICs, acknowledging the community-based approach can be effective in prevention and control of Type 2 diabetes. Due to the heterogeneity across study designs, outcomes and in terms of variation and duration of interventions, only limited conclusions can be drawn about the effectiveness of interventions. More evidence from randomized controlled trials on culturally tailored, community-based interventions is needed to compare findings and test implementation in practice.

Lay Advisor Interventions in Rural Populations: A Systematic Review and Meta-analysis

CONTEXT

Age-adjusted death rates for heart disease are higher in rural areas than in urban areas. Lay advisors could potentially facilitate improvement in cardiovascular health outcomes. The aim of this systematic review and meta-analysis is to estimate lay advisor intervention effects on cardiovascular health metrics in rural populations.

EVIDENCE ACQUISITION

Searches of databases including MEDLINE, CINAHL, and Scopus from 1975 through October 2017 retrieved 323 citations, of which 272 abstracts were reviewed. Two authors independently abstracted data from eligible studies. Analysis was conducted in March 2018.

EVIDENCE SYNTHESIS

Of 21 articles included in the systematic review, eight were RCTs and 13 were pre- and post-intervention studies. Of the RCTs, three took place in the U.S. Only two studies had low risk of bias. Using a random effects model, meta-analysis of six RCTs (1,641 participants) showed that lay advisor interventions in rural residents were associated with improvement in HbA1c of 0.4% (95% CI=0.13, 0.66, p=0.004, I²=60.65%). From four RCTs (873 participants), lay advisor interventions significantly improved BMI with pooled effect of 2.18 (95% CI=1.13, 3.24, p<0.001, I²=0.00%). Most studies had normal baseline blood pressure and cholesterol levels before intervention, and no significant effects were noted for these outcomes. Diverse types of measures used for diet, physical activity, and smoking precluded statistical synthesis.

CONCLUSIONS

Lay advisor interventions had significant positive effects on glycemic control and BMI for rural residents; however, further rigorous studies are needed in U.S. rural populations, and elements of effective lay advisor interventions require further investigation.

Community groups or mobile phone messaging to prevent and control type 2 diabetes and intermediate hyperglycaemia in Bangladesh (DMagic): a cluster-randomised controlled trial

BACKGROUND

Strategies are needed to prevent and control type 2 diabetes and intermediate hyperglycaemia, which together affect roughly a third of adults in Bangladesh. We aimed to assess the effects of mHealth and community mobilisation on the prevalence of intermediate hyperglycaemia and diabetes among the general adult population in rural Bangladesh, and to assess the effect of these interventions on the incidence of type 2 diabetes among people with intermediate hyperglycaemia within the study population.

METHODS

DMagic was a three-arm, cluster-randomised trial of participatory community mobilisation, mHealth mobile phone messaging, and usual care (control) in 96 villages (population roughly 125 000) in Bangladesh. Community mobilisation involved 18 monthly group meetings, led by lay facilitators, applying a participatory learning and action (PLA) cycle focused on diabetes prevention and control. mHealth involved twice-weekly voice messages over 14 months promoting behaviour change to reduce diabetes risk. The primary outcomes were the combined prevalence of type 2 diabetes and intermediate hyperglycaemia in the overall population at the end of the intervention implementation period, and 2-year cumulative incidence of type 2 diabetes in a cohort with intermediate hyperglycaemia at baseline. Primary outcomes were assessed through fasting blood glucose concentrations and 2-h oral glucose tolerance tests among a cross-section of adults aged 30 years and older and a cohort of individuals identified with intermediate hyperglycaemia. Prevalence findings are based on a cross-sectional survey at the end of the study; incidence findings are based on 2-year follow-up survey of a cohort of individuals identified with intermediate hyperglycaemia through a cross-sectional survey at baseline. We also assessed the cost-effectiveness of the interventions. This trial is registered with the ISRCTN registry, number ISRCTN41083256, and is completed.

FINDINGS

The study took place between June 27, 2015, and June 28, 2018, with the PLA intervention running in 32 villages from June, 2016, to December, 2017, and the mHealth intervention running in 32 villages from Oct 21, 2016, to Dec 24, 2017. End-of study prevalence was assessed in 11 454 individuals and incidence in 2100 individuals. There was a large reduction in the combined prevalence of type 2 diabetes and intermediate hyperglycaemia in the PLA group compared with the control group at the end of the study (adjusted [for stratification, clustering, and wealth] odds ratio [aOR] 0·36 [0·27-0·48]), with an absolute reduction of 20·7% (95% CI 14·6-26·7). Among 2470 adults with intermediate hyperglycaemia at baseline, 2100 (85%) were followed-up at 2 years. The 2-year cumulative incidence of diabetes in this cohort was significantly lower in the PLA group compared with control (aOR 0·39, 0·24-0·65), representing an absolute incidence reduction of 8·7% (3·5-14·0). There was no evidence of effect of mHealth on combined prevalence of intermediate hyperglycaemia and diabetes (aOR 0·93, 0·74-1·16) or the incidence of diabetes (1·02, 0·73-1·43). The incremental cost-effectiveness ratios for PLA were INT$316 per case of intermediate hyperglycaemia or type 2 diabetes prevented and $6518 per case of type 2 diabetes prevented among individuals with intermediate hyperglycaemia.

INTERPRETATION

Our data provide strong evidence to support the use of community mobilisation based on PLA to prevent type 2 diabetes in this rural Bangladeshi population. Despite raising knowledge and awareness of diabetes, the mHealth intervention did not change disease outcomes in our population. Replication studies in other populations should be a priority.

Culturally Appropriate Peer-Led Behavior Support Program for African Americans With Type 2 Diabetes

Current literature poorly defines the specific ways trained peer supporter influences health care behaviors. This study attempts to identify the key defining features of a culturally appropriate peer support program for African Americans with type 2 diabetes by exploring participants experiences related to assistance with daily disease management, emotional support, linkage to clinic care and community resources, and ongoing support. We used a qualitative interpretive descriptive approach to collect data through semi-structured interviews from 20 African Americans with type 2 diabetes participating in a peer support program. Interviews captured participants' background and experiences with the peer supporter and evaluated the cultural appropriateness of the peer support intervention. Data was coded deductively using predetermined codes found in the peer support literature and inductively to identify emergent themes. Three specific themes were identified namely [1] healthy behaviors [2] frequent telephonic contact and [3] emotional support as a by-product of other support activities. These findings mirror the broader literature on what constitutes culturally appropriate peer support programs for ethnic minorities. We recommend the inclusion of culturally appropriate peer support program to complement diabetes management as targeted plan for improvement in clinical care and ultimately, diabetes outcome.

Factors associated with self-management among Vietnamese adults with type 2 diabetes

AIM

The study described diabetes self-management (DSM), diabetes knowledge, family and friends' support, healthcare providers' support, belief in treatment effectiveness and diabetes management self-efficacy, and explored DSM's associations among Vietnamese adults with type 2 diabetes mellitus (T2DM).

DESIGN

A cross-sectional design was applied.

METHODS

The study used self-report questionnaires to collect data from 198 participants. Descriptive statistics and structural equation modelling (SEM) was used for data analysis.

RESULTS

Vietnamese adults with T2DM performed DSM limitedly in certain aspects. They had strong belief in treatment effectiveness, good family and friends support, limited diabetes knowledge, healthcare professional support and self-efficacy. Their DSM was directly associated with diabetes knowledge, family and friends' support, healthcare providers' support, belief in treatment effectiveness and diabetes management self-efficacy. Their DSM was indirectly associated with diabetes knowledge and family and friends' support through their belief in treatment effectiveness and diabetes management self-efficacy.

Self-management of diabetes in Sub-Saharan Africa: a systematic review

BACKGROUND

The prevalence of diabetes in sub-Saharan Africa has increased rapidly over the last years. Self-management is a key element for the proper management, but strategies are currently lacking in this context. This systematic review aims to describe the level of self-management among persons living with type 2 diabetes mellitus in sub-Saharan Africa.

METHOD

Relevant databases including PubMed, Web of Science and Google Scholar were searched up to September 2016. Studies reporting self-management behavior of people with type 2 diabetes mellitus and living in sub-Saharan Africa were included.

RESULTS

A total of 550 abstracts and 109 full-text articles were assessed. Forty-three studies, mainly observational, met the inclusion criteria. The studies showed that patients rarely self-monitored their glucose levels, had low frequency/duration of physical activity, moderately adhered to recommended dietary and medication behavior, had poor level of knowledge regarding diabetes related complications and sought traditional or herbal medicines beside of their biomedical treatment. The analysis also revealed a lack of studies on psychosocial aspects.

CONCLUSION

Except for the psychosocial area, there is a good amount of recent studies on self-management behavior of type 2 diabetes mellitus sub-Saharan Africa. These studies indicate that self-management in sub-Saharan Africa is poor and therefore a serious threat to the health of individuals and the health systems capacity.

Protocol of economic evaluation and equity impact analysis of mHealth and community groups for prevention and control of diabetes in rural Bangladesh in a three-arm cluster randomised controlled trial

INTRODUCTION

Type 2 diabetes mellitus (T2DM) is one of the leading causes of death and disability worldwide, generating substantial economic burden for people with diabetes and their families, and to health systems and national economies. Bangladesh has one of the largest numbers of adults with diabetes in the South Asian region. This paper describes the planned economic evaluation of a three-arm cluster randomised control trial of mHealth and community mobilisation interventions to prevent and control T2DM and non-communicable diseases' risk factors in rural Bangladesh (D-Magic trial).

METHODS AND ANALYSIS

The economic evaluation will be conducted as a within-trial analysis to evaluate the incremental costs and health outcomes of mHealth and community mobilisation interventions compared with the status quo. The analyses will be conducted from a societal perspective, assessing the economic impact for all parties affected by the interventions, including implementing agencies (programme costs), healthcare providers, and participants and their households. Incremental cost-effectiveness ratios (ICERs) will be calculated in terms of cost per case of intermediate hyperglycaemia and T2DM prevented and cost per case of diabetes prevented among individuals with intermediate hyperglycaemia at baseline and cost per mm Hg reduction in systolic blood pressure. In addition to ICERs, the economic evaluation will be presented as a cost-consequence analysis where the incremental costs and all statistically significant outcomes will be listed separately. Robustness of the results will be assessed through sensitivity analyses. In addition, an analysis of equity impact of the interventions will be conducted.

ETHICS AND DISSEMINATION

The approval to conduct the study was obtained by the University College London Research Ethics Committee (4766/002) and by the Ethical Review Committee of the Diabetic Association of Bangladesh (BADAS-ERC/EC/t5100246). The findings of this study will be disseminated through different means within academia and the wider policy sphere.

Effectiveness of peer support to increase uptake of retinal examination for diabetic retinopathy: study protocol for the DURE pragmatic cluster randomized clinical trial in Kirinyaga, Kenya

BACKGROUND

All patients with diabetes are at risk of developing diabetic retinopathy (DR), a progressive and potentially blinding condition. Early treatment of DR prevents visual impairment and blindness. The natural history of DR is that it is asymptomatic until the advanced stages, thus annual retinal examination is recommended for early detection. Previous studies show that the uptake of regular retinal examination among people living with diabetes (PLWD) is low. In the Uptake of Retinal Examination in Diabetes (DURE) study, we will investigate the effectiveness of a complex intervention delivered within diabetes support groups to increase uptake of retinal examination.

METHODS

The DURE study will be a two-arm pragmatic cluster randomized clinical trial in Kirinyaga County, Kenya. Diabetes support groups will be randomly assigned to either the intervention or usual care conditions in a 1:1 ratio. The participants will be 700 PLWD who are members of support groups in Kirinyaga. To reduce contamination, the unit of randomization will be the support group. Peer supporters in the intervention arm will receive training to deliver the intervention. The intervention will include monthly group education on DR and individual member reminders to take the eye examination. The effectiveness of this intervention plus usual care will be compared to usual care practices alone. Participant data will be collected at baseline. The primary outcome is the proportion of PLWD who take up the eye examination at six months. Secondary outcomes include the characteristics of participants and peer supporters associated with uptake of eye examination for DR. Intention-to-treat analysis will be used to evaluate the primary and secondary outcomes.

DISCUSSION

Eye care programs need evidence of the effectiveness of peer supporter-led health education to improve attendance to retinal screening for the early detection of DR in an African setting. Given that the intervention combines standardization and flexibility, it has the potential to be adopted in other settings and to inform policies to promote DR screening.

From HIV prevention to non-communicable disease health promotion efforts in sub-Saharan Africa: A Narrative Review

OBJECTIVE

To synthesize published literature on noncommunicable disease (NCD) behavior change communication (BCC) interventions in sub-Saharan Africa (SSA) among persons living with HIV (PLHIV) and in the general population to inform efforts to adopt similar HIV and NCD BCC intervention activities.

METHODS

We conducted a literature review of NCD BCC interventions and included 20 SSA-based studies. Inclusion criteria entailed describing a BCC intervention targeting any four priority NCDs (cardiovascular disease, type 2 diabetes, cervical cancer, and depression) or both HIV and any of the NCDs. The RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework was used to assess potential public health impact of these studies. We also solicited expert opinions from 10 key informants on the topic of HIV/NCD health promotion in five SSA countries.

RESULTS

The BCC interventions reviewed targeted multiple parts of the HIV and NCD continuum at both individual and community levels. Various strategies (i.e. health education, social marketing, motivational interviewing, mobile health, and peer support) were employed. However, few studies addressed more than one dimension of the RE-AIM framework. Opinions solicited from the key informants supported the feasibility of integrating HIV and NCD BCC interventions in SSA potentially improving access, service provision and service demand, especially for marginalized and vulnerable populations.

CONCLUSION

Although HIV/NCD integration can improve effectiveness of preventive services at individual and community levels, potential public health impact of such approaches remain unknown as reach, adoptability, and sustainability of both integrated and nonintegrated NCD BCC approaches published to date have not been well characterized.

Evaluation of a multi-faceted diabetes care program including community-based peer educators in Takeo province, Cambodia, 2007-2013

INTRODUCTION

Early detection and treatment for diabetes are essential for reducing disability and death from the disease. Finding effective screening and treatment for individuals living with diabetes in resource-limited countries is a challenge. MoPoTsyo, a Cambodian non-governmental organization, addressed this gap by utilizing a multi-pronged approach with community-based peer educators, access to laboratory procedures, local outpatient medical consultation, and a revolving drug fund. This study evaluated outcomes of MoPoTsyo's diabetes program in Takeo Province by assessing glycemic and blood pressure outcomes for individuals diagnosed with diabetes over a 24-month follow-up period between 2007-2013.

METHODS

This is a retrospective cohort analysis of records without a comparison group. We calculated the mean fasting blood glucose (FBG) and blood pressure (BP) at regular intervals of follow-up. The proportion of patients reaching recommended treatment targets for FBG and BP was assessed.

RESULTS

Of the 3411 patients enrolled in the program, 2230 were included in the study. The cohort was predominantly female (68.9%) with a median age of 54 years. Median follow-up time in the program was 16 months (4.9-38.4 months). Mean FBG decreased 63.9 mg/dl in mean FBG (95% CI 58.5 to 69.3) at one year of follow-up (p<0.001). After one year, 45% (321/708) of patients achieved goal FBG < 126. Of the 41.6% (927/2230) with elevated BP at enrollment, systolic and diastolic BP levels significantly decreased (p<0.001) by 16.9 mmHg (95% CI 1.2 to 22.9) and 10 mm Hg (95% CI 0.7 to 12.9) respectively between enrollment and one year of follow-up. At one year of follow-up, 51.1%% (183/355) of these patients reached the BP goal < 140/90.

CONCLUSION

The improved outcome indicators of diabetes care for MoPoTsyo's Takeo program evaluation showed promise. The program demonstrated a reasonable and practical approach to delivering effective diabetes care in a rural area and may serve as a model for other low-income communities. Future prospective evaluations with more complete data are necessary for longer-term outcomes.

The Impact of Peer Support Program on Adherence to the Treatment Regimen in Patients with Hypertension: A Randomized Clinical Trial Study

Background:

High blood pressure is the greatest risk factor of death, and patients should manage to control it. Peer support program is used to control chronic diseases. This study aims to determine the effect of peer support program on adherence to the regimen in patients suffering from hypertension.

Materials and Methods:

This study is a clinical trial conducted among 64 patients with hypertension referring to the Hypertension Research Center (Isfahan. Iran). The information was collected in three stages – before the start of intervention, immediately after, and 1 month after the intervention using a questionnaire of adherence to the treatment regimen for high blood pressure. The questionnaires were filled using a questioning method by patients who were not aware of the study. The experimental group attended 6 sessions of the peer support program (1 hour), and the control group attended two sessions held by the researcher. Data were analyzed using the Statistical Package for the Social Sciences version 18 software, and statistical tests were analyzed using independent t-test and analysis of variance with repeated measures.

Results:

Before the intervention, there was no significant difference in adherence to the treatment regimen score between the two groups regarding the three aspects of medication regimen, diet, and activity program. Increase in scores of control group immediately after and 1 month after peer support program was higher (p < 0.001) compared to before the intervention.

Conclusions:

This study showed that peer support programs had a positive impact on adherence to the treatment regimen in patients suffering from hypertension.

The effect of community groups and mobile phone messages on the prevention and control of diabetes in rural Bangladesh: study protocol for a three-arm cluster randomised controlled trial

Background

Increasing rates of type 2 diabetes mellitus place a substantial burden on health care services, communities, families and individuals living with the disease or at risk of developing it. Estimates of the combined prevalence of intermediate hyperglycaemia and diabetes in Bangladesh vary, and can be as high as 30% of the adult population. Despite such high prevalence, awareness and control of diabetes and its risk factors are limited. Prevention and control of diabetes and its complications demand increased awareness and action of individuals and communities, with positive influences on behaviours and lifestyle choices. In this study, we will test the effect of two different interventions on diabetes occurrence and its risk factors in rural Bangladesh.

Methods/design

A three-arm cluster randomised controlled trial of mobile health (mHealth) and participatory community group interventions will be conducted in four rural upazillas in Faridpur District, Bangladesh. Ninety-six clusters (villages) will be randomised to receive either the mHealth intervention or the participatory community group intervention, or be assigned to the control arm. In the mHealth arm, enrolled individuals will receive twice-weekly voice messages sent to their mobile phone about prevention and control of diabetes. In the participatory community group arm, facilitators will initiate a series of monthly group meetings for men and women, progressing through a Participatory Learning and Action cycle whereby group members and communities identify, prioritise and tackle problems associated with diabetes and the risk of developing diabetes. Both interventions will run for 18 months. The primary outcomes of the combined prevalence of intermediate hyperglycaemia and diabetes and the cumulative 2-year incidence of diabetes among individuals identified as having intermediate hyperglycaemia at baseline will be evaluated through baseline and endline sample surveys of permanent residents aged 30 years or older in each of the study clusters. Data on blood glucose level, blood pressure, body mass index and hip-to-waist ratio will be gathered through physical measurements by trained fieldworkers. Demographic and socioeconomic data, as well as data on knowledge of diabetes, chronic disease risk factor prevalence and quality of life, will be gathered through interviews with sampled respondents.

Discussion

This study will increase our understanding of diabetes and other non-communicable disease burdens and risk factors in rural Bangladesh. By documenting and evaluating the delivery, impact and cost-effectiveness of participatory community groups and mobile phone voice messaging, study findings will provide evidence on how population-level strategies of community mobilisation and mHealth can be implemented to prevent and control noncommunicable diseases and risk factors in this population.

Cardiovascular risk outcome and program evaluation of a cluster randomised controlled trial of a community-based, lay peer led program for people with diabetes

Background

The 2013 Global Burden of Disease Study demonstrated the increasing burden of diabetes and the challenge it poses to the health systems of all countries. The chronic and complex nature of diabetes requires active self-management by patients in addition to clinical management in order to achieve optimal glycaemic control and appropriate use of available clinical services. This study is an evaluation of a “real world” peer support program aimed at improving the control and management of type 2 diabetes (T2DM) in Australia.

Methods

The trial used a randomised cluster design with a peer support intervention and routine care control arms and 12-month follow up. Participants in both arms received a standardised session of self-management education at baseline. The intervention program comprised monthly community-based group meetings over 12 months led by trained peer supporters and active encouragement to use primary health care and other community resources and supports related to diabetes. Clinical, behavioural and other measures were collected at baseline, 6 and 12 months. The primary outcome was the predicted 5 year cardiovascular disease risk using the United Kingdom Prospective Diabetes Study (UKPDS) Risk Equation at 12 months. Secondary outcomes included clinical measures, quality of life, measures of support, psychosocial functioning and lifestyle measures.

Results

Eleven of 12 planned groups were successfully implemented in the intervention arm. Both the usual care and the intervention arms demonstrated a small reduction in 5 year UKPDS risk and the mean values for biochemical and anthropometric outcomes were close to target at 12 months. There were some small positive changes in self-management behaviours.

Conclusions

The positive changes in self-management behaviours among intervention participants were not sufficient to reduce cardiovascular risk, possibly because approximately half of the study participants already had quite well controlled T2DM at baseline. Future research needs to address how to enhance community based programs so that they reach and benefit those most in need of resources and supports to improve metabolic control and associated clinical outcomes.

"I don't have options but to persevere." Experiences and practices of care for HIV and diabetes in rural Tanzania: a qualitative study of patients and family caregivers

Background

The high prevalence of chronic diseases in Tanzania is putting a strain on the already stretched health care services, patients and their families. This study sought to find out how health care for diabetes and HIV is perceived, practiced and experienced by patients and family caregivers, to inform strategies to improve continuity of care.

Methods

Thirty two in-depth interviews were conducted among 19 patients (10 HIV, 9 diabetes) and 13 family caregivers (6 HIV, 7 diabetes). Diabetes patients and caregivers were accessed through one referral facility. HIV patients and caregivers were accessed through HIV clinics at the district hospital, one health centre and one dispensary respectively. The innovative care for chronic conditions framework informed the study design. Data was analysed with the help of Nvivo 10.

Results

Three major themes emerged; preparedness and practices in care, health care at health facilities and community support in care for HIV and diabetes. In preparedness and practices, HIV patients and caregivers knew more about aspects of HIV than did diabetes patients and caregivers on diabetes aspects. Continued education on care for the conditions was better structured for HIV than diabetes. On care at facilities, HIV and diabetes patients reported that they appreciated familiarity with providers, warm reception, gentle correction of mistakes and privacy during care. HIV services were free of charge at all levels. Costs involved in seeking services resulted in some diabetes patients to not keep appointments. There was limited community support for care of diabetes patients. Community support for HIV care was through community health workers, patient groups, and village leaders.

Conclusion

Diabetes and HIV have socio-cultural and economic implications for patients and their families. The HIV programme is successfully using decentralization of health services, task shifting and CHWs to address these implications. For diabetes and NCDs, decentralization and task shifting are also important and, strengthening of community involvement is warranted for continuity of care and patient centeredness in care. While considering differences between HIV and diabetes, we have shown that Tanzania’s rich experiences in community involvement in health can be leveraged for care and treatment of diabetes and other NCDs.

Peer Support Training Improved the Glycemic Control, Insulin Management, and Diabetic Behaviors of Patients with Type 2 Diabetes in Rural Communities of Central China: A Randomized Controlled Trial

Background

The efficacy of peer support in Chinese diabetes patients is still uncertain. The purpose of this study was to observe the effects of a peer support program on the outcomes of patients with type 2 diabetes who received community-based insulin therapy in rural communities of central China.

Material/Methods

Two hundred and eight eligible patients with type 2 diabetes were randomly assigned into the traditional training group (control group, n=111) and peer support intervention group (peer group, n=97) between June 2013 and January 2014 in 2 rural communities of Jingzhou area, China. Both groups received 3-month traditional training, followed by another 4-month traditional training or peer support training, respectively. At baseline and 7 months after treatment, the blood glycemic level was evaluated by biochemical detection. Capacities of self-management and knowledge related to insulin usage were assessed by questionnaire survey.

Results

Ninety-seven and ninety patients completed this study in the control group and peer group, respectively. There was no significant difference in age, gender, diabetes duration, insulin usage time, and complications between the 2 groups at baseline (P>0.05). Compared with the control group, peer group patients achieved a more significant decrease in blood glycosylated hemoglobin levels (P<0.05), increase in knowledge related to insulin usage, and increase of diabetes self-management ability (P<0.05).

Conclusions

Peer support intervention effectively improves outcomes of patients with type 2 diabetes in rural communities of central China.

Advancing the science of dissemination and implementation in behavioral medicine: evidence and progress

The enormous time lag between the discovery of new knowledge and its implementation poses a significant challenge to improving public health because of the very slow uptake into policy and practice. The field of dissemination and implementation research in behavioral medicine is receiving increased attention because of the keen interest in accelerating knowledge transfer from relevant research to improve the health and wellbeing of populations in many different settings, contexts, and countries around the world. This is particularly important in high-risk populations, resource-poor and developing regions of the world where the difference in health systems, languages, and cultures very significantly influences the translation of evidence into policy and practice. Moreover, demonstrating the broader societal and economic value of behavioral interventions in settings where they are implemented can further support the sustainability, uptake, and implementation of these findings in other settings and contexts. This special issue presents a series of empirical studies, reviews, and case studies that address dissemination, implementation, and translation issues in both developed and developing countries. Specifically, the learnings from the application of many and varied theories and research methodologies are very relevant for bridging the current division between research findings and their translation and uptake into policy and practice.

Community-based peer support significantly improves metabolic control in people with Type 2 diabetes in Yaoundé, Cameroon

AIMS

To examine the effectiveness of a community-based multilevel peer support intervention in addition to usual diabetes care on improving glycaemic levels, blood pressure and lipids in patients with Type 2 diabetes in Yaoundé, Cameroon.

METHODS

A total of 96 subjects with poorly controlled Type 2 diabetes (intervention group) and 96 age- and sex-matched controls were recruited and followed up over 6 months. The intervention subjects underwent a peer support intervention through peer-led group meetings, personal encounters and telephone calls. Both intervention subjects and controls continued their usual clinical care. HbA1c , blood pressure, blood lipids and self-care behaviours were measured at 0 and 6 months.

RESULTS

There was significant reduction in HbA1c in the intervention group [-33 mmol/mol (-3.0%)] compared with controls [-14 mmol/mol (-1.3%)]; P < 0.001. Peer support also led to significant reductions in fasting blood sugar (-0.83 g/l P < 0.001), cholesterol (-0.54 g/l P < 0.001), HDL (-0.09 g/l, P < 0.001), BMI (-2.71 kg/m² P < 0.001) and diastolic pressure (-6.77 mmHg, P < 0.001) over the 6-month period. Also, diabetes self-care behaviours in the intervention group improved significantly over the 6 months of peer support.

CONCLUSION

Community-based peer support, in addition to usual care, significantly improved metabolic control in patients with uncontrolled Type 2 diabetes in Yaoundé, Cameroon. This could provide a model for optimizing diabetes care and control in other settings with limited healthcare and financial resources.
