Diabetes in sub-Saharan Africa: from clinical care to health policy

The contextual awareness, response and evaluation (CARE) diabetes project: study design for a quantitative survey of diabetes prevalence and non-communicable disease risk in Ga Mashie, Accra, Ghana

Diabetes is estimated to affect between 3.3% and 8.3% of adults in Ghana, and prevalence is expected to rise. The lack of cost-effective diabetes prevention programmes designed specifically for the Ghanaian population warrants urgent attention. The Contextual Awareness, Response and Evaluation (CARE): Diabetes Project in Ghana is a mixed methods study that aims to understand diabetes in the Ga Mashie area of Accra, identify opportunities for community-based intervention and inform future diabetes prevention and control strategies. This paper presents the study design for the quantitative survey within the CARE project. This survey will take place in the densely populated Ga Mashie area of Accra, Ghana. A household survey will be conducted using simple random sampling to select households from 80 enumeration areas identified in the 2021 Ghana Population and Housing Census. Trained enumerators will interview and collect data from permanent residents aged ≥ 25 years. Pregnant women and those who have given birth in the last six months will be excluded. Data analysis will use a combination of descriptive and inferential statistics, and all analyses will account for the cluster sampling design. Analyses will describe the prevalence of diabetes, other morbidities, and associated risk factors and identify the relationship between diabetes and physical, social, and behavioural parameters. This survey will generate evidence on drivers and consequences of diabetes and facilitate efforts to prevent and control diabetes and other NCDs in urban Ghana, with relevance for other low-income communities.

Incidence and predictors of diabetic foot ulcer among patients with diabetes mellitus in a diabetic follow-up clinic in Central Ethiopia: a retrospective follow-up study

BACKGROUND

Diabetic foot ulcer is a major medical, social, and economic problem, and a leading cause of hospitalisations, increased morbidity, and mortality. Despite a rising occurrence, there is a dearth of data on the incidence and its predictors.

OBJECTIVE

To assess the incidence and predictors of diabetic foot ulcers among patients with diabetes mellitus in a diabetic follow-up clinic in Central Ethiopia.

DESIGN

Retrospective follow-up study design.

PARTICIPANTS

A total of 418 newly diagnosed diabetes mellitus patients from 1 January 2012 to 31 December 2022. A computer-generated simple random sampling method was used to select the study participants. Data were collected using a structured data extraction checklist. The collected data were entered into Epi Info V.7.2 and exported to STATA V.14 for analysis. To estimate survival time, the Kaplan-Meier method was used, and the survival difference was tested using a log-rank test.

OUTCOME MEASURES

The Cox proportional hazard model was fitted to identify the predictors of diabetic foot ulcer development. The strength of the association was estimated using an adjusted hazard ratio (AHR) with a 95% confidence interval (CI), and statistical significance was proclaimed at a p<0.05.

RESULT

The overall incidence of diabetic foot ulcer was 1.51 cases (95% CI 1.03 to 2.22) per 100 person-years of observation. The cumulative incidence was 6.2% (95% CI 4.1% to 8.6%) over 10 years. The median time of follow-up was 45 months (IQR 21-73). Diastolic blood pressure of 90 mm Hg or above (AHR 2.91, 95% CI 1.25 to 6.77), taking combined medication (AHR 3.24, 95% CI 1.14 to 9.19) and having a peripheral arterial disease (AHR 5.26, 95% CI 1.61 to 17.18) were statistically significant predictors of diabetic foot ulcer development.

CONCLUSION

The risk of occurrence of diabetic foot ulcer was relatively high. Diastolic blood pressure level, combined medication and peripheral arterial disease were independent predictors of diabetic foot ulcer development. Hence, close monitoring and proper interventions are essential.

Transfers between health facilities of people living with diabetes attending primary health care services in the Western Cape Province of South Africa: A retrospective cohort study

OBJECTIVES

Transfers between health facilities of people living with HIV attending primary health care (PHC) including hospital to PHC facility, PHC facility to hospital and PHC facility to PHC facility transfers occur frequently, affect health service planning, and are associated with disengagement from care and viraemia. Data on transfers among people living with diabetes attending PHC, particularly transfers between PHC facilities, are few. We assessed the transfer incidence rate of people living with diabetes attending PHC, and the association between transfers between PHC facilities and subsequent HbA1c values.

METHODS

We analysed data on HbA1c tests at public sector facilities in the Western Cape Province (2016-March 2020). Individuals with an HbA1c in 2016-2017 were followed-up for 27 months and included in the analysis if ≥18 years at first included HbA1c, ≥2 HbA1cs during follow-up and ≥1 HbA1c at a PHC facility. A visit interval was the duration between two consecutive HbA1cs. Successive HbA1cs at different facilities of any type indicated any transfer, and HbA1cs at different PHC facilities indicated a transfer between PHC facilities. Mixed effects logistic regression adjusted for sex, age, rural/urban facility attended at the start of the visit interval, disengagement (visit interval >14 months) and a hospital visit during follow-up assessed the association between transfers between PHC facilities and HbA1c >8%.

RESULTS

Among 102,813 participants, 22.6% had ≥1 transfer of any type. Including repeat transfers, there were 29,994 transfers (14.4 transfers per 100 person-years, 95% confidence interval [CI] 14.3-14.6). A total of 6996 (30.1%) of those who transferred had a transfer between PHC facilities. Visit intervals with a transfer between PHC facilities were longer (349 days, interquartile range [IQR] 211-503) than those without any transfer (330 days, IQR 182-422). The adjusted relative odds of an HbA1c ≥8% after a transfer between PHC facilities versus no transfer were 1.20 (95% CI 1.05-1.37).

CONCLUSION

The volume of transfers involving PHC facilities requires consideration when planning services. Individuals who transfer between PHC facilities require additional monitoring and support.

Exposure to mass media chronic health campaign messages and the uptake of non-communicable disease screening in Ghana

The main goal of this study was to examine the relationship between exposure to mass media health campaign massages and the uptake of non-communicable diseases (NCDs) screening services in Ghana and whether this relationship differs by place of residence. Available evidence suggests a general low uptake of NCDs screening in developing country settings. Unfortunately, many NCDs evolve very slowly and are consequently difficult to detect early especially in situations where people do not screen regularly and in settings where awareness is low. In this study, we contribute to understanding the potential role of the media in scaling up NCDs screening in developing countries. We fitted multivariate logistic regression models to a sample of 1337 individual surveys which were collected at the neighborhood level in three Ghanaian cities. Overall, the results show that exposure to mass media chronic NCD health campaign messages was significantly associated with increased likelihood of screening for NCDs. The results further highlight neighborhood-level disparities in the uptake of NCDs screening services as residents of low-income and deprived neighborhoods were significantly less likely to report being screened for NCDs. Other factors including social capital, knowledge about the causes of NCDs and self-rated health predicted the likelihood of chronic NCDs screening. The results demonstrate mass media can be an important tool for scaling up NCDs screening services in Ghana and similar contexts where awareness might be low. However, place-based disparities need to be addressed.

Phenotypic characterization of nonautoimmune diabetes in adult Ugandans with low body mass index

Background

Type 2 diabetes is common in relatively lean individuals in sub-Saharan Africa. It is unclear whether phenotypic differences exist between underweight and normal-weight African patients with type 2 diabetes. This study compared specific characteristics between underweight (body mass index <18.5 kg/m2) and normal-weight (body mass index of 18.5-24.9 kg/m2) adult Ugandans with new-onset nonautoimmune diabetes.

Methods

We collected the demographic, clinical, anthropometric, and metabolic characteristics of 160 participants with nonobese new-onset type 2 diabetes (defined as diabetes diagnosed <3 months, body mass index <25 kg/m2, and absence of islet-cell autoimmunity). These participants were categorized as underweight and normal weight, and their phenotypic characteristics were compared.

Results

Of the 160 participants with nonobese new-onset type 2 diabetes, 18 participants (11.3%) were underweight. Compared with those with normal weight, underweight participants presented with less co-existing hypertension (5.6% versus 28.2%, p = 0.04) and lower median visceral fat levels [2 (1-3) versus 6 (4-7), p < 0.001], as assessed by bioimpedance analysis. Pathophysiologically, they presented with a lower median 120-min post-glucose load C-peptide level [0.29 (0.13-0.58) versus 0.82 (0.39-1.50) nmol/l, p = 0.04] and a higher prevalence of insulin deficiency (66.7% versus 31.4%, p = 0.003).

Conclusion

This study demonstrates that nonautoimmune diabetes occurs in underweight individuals in sub-Saharan Africa and is characterized by the absence of visceral adiposity, reduced late-phase insulin secretion, and greater insulin deficiency. These findings necessitate further studies to inform how the prevention, identification, and management of diabetes in such individuals can be individualized.

Exploring type 2 diabetes self-management practices in rural Bangladesh: facilitators, barriers and expectations-a qualitative study protocol

BACKGROUND

Type 2 diabetes mellitus (T2DM) is a global public health crisis impacting low-income and middle-income countries such as Bangladesh. While self-management is encouraged for individuals with T2DM, there is a significant lack of knowledge regarding the factors of facilitators, barriers and expectations associated with T2DM self-management in Bangladesh. This research aims to investigate the potential elements that support, impede and are anticipated in the effective practice of self-management for T2DM in rural areas of Bangladesh.

METHODS AND ANALYSIS

This study will use an exploratory qualitative approach. 16 focus group discussions, 13 in-depth interviews and 9 key informant interviews will be conducted among multilevel stakeholders, including people with T2DM, their caregivers, healthcare providers, health managers/administrators and policy planners. Interviews will be audio-recorded, transcribed, translated and analysed using thematic analysis.

ETHICS AND DISSEMINATION

This research project has been approved by the Monash University Human Research Ethics Committee (project reference number: 39483) and the Ethical Review Committee of the Centre for Injury Prevention and Research, Bangladesh (Memo: CIPRB/ERC/2023/14). Research findings will be disseminated in peer-reviewed journals and conference presentations. Published reports will include group data. Individual data privacy will be strictly maintained.

Independent Correlates of Glycemic Control among Adults with Diabetes in South Africa

BACKGROUND

Globally, the prevalence of diabetes is increasing, especially in low- and middle-income countries (LMICs), including those in the sub-Saharan African region. However, the independent socioeconomic correlates of glycemic control as measured by hemoglobin A1C have yet to be identified. Therefore, the aim of this analysis was to understand the independent correlates of glycemic control in South Africa.

METHODS

Data from the 2016 South Africa Demographic and Health Survey on adults with diabetes were used for this analysis. The dependent variable, glycemic control, was defined using hemoglobin A1c (HbA1c). Independent variables included: age, gender, ethnicity, marital status, region, urban/rural residence, ability to read, education, insurance, wealth, occupation, and employment in the last year. Analysis of variance was used to test for differences in mean HbA1c for each category of all independent variables, and a fully adjusted linear regression model was used to identify independent correlates of glycemic control (HbA1c).

RESULTS

Among the 772 people included in this analysis, there were significant differences in mean HbA1c by age (p < 0.001), ethnicity (p < 0.001), place of residence (p = 0.024), wealth index (p = 0.001), and employment in the last year (p = 0.008). Independent correlates of HbA1c included age, ethnicity, and wealth index.

CONCLUSIONS

This study used data from a large diverse population with a high prevalence of diabetes in sub-Saharan Africa and provides new evidence on the correlates of glycemic control and potential targets for interventions designed to lower HbA1c and improve diabetes-related health outcomes of adults in South Africa.

HIV and type 2 diabetes: An evolving story

INTRODUCTION

Diabetes is widely reported to be more common in people living with HIV (PLWH). Much of the data supporting this originated during the earlier HIV era. The perceived increased risk of type 2 diabetes is reflected in HIV clinical guidelines that recommend screening for diabetes in PLWH on anti-retroviral therapy (ART). However, international HIV clinical guidelines do not agree on the best marker of glycaemia to screen for diabetes. This stems from studies that suggest HbA1c underestimates glycaemia in PLWH.

METHODS

Within this review we summarise the literature surrounding the association of HIV and type 2 diabetes and how this has changed over time. We also present the evidence on HbA1c discrepancy in PLWH.

CONCLUSION

We suggest there is no basis to any international guidelines to restrict HbA1c based on HIV serostatus. We recommend, using the current evidence, that PLWH should be screened annually for diabetes in keeping with country specific guidance. Finally, we suggest future work to elucidate phenotype and natural history of type 2 diabetes in PLWH across all populations.

The role of social support and self-management on glycemic control of type 2 diabetes mellitus with complications in Ghana: A cross-sectional study

Background and Aims

Diabetes mellitus (DM) can result in detrimental complications which are connected with long-term impairments and disabilities. Chronic complications are well-known consequences of type 2 diabetes mellitus (T2DM) progression, which reduce patient quality of life, place a burden on the healthcare system, and increase mortality. Measures to promote health outcomes for people with DM are scanty; the study therefore aimed at determining the effects of self-management and social support on glycemic control of T2DM with complications in Ghana.

Methods

A cross-sectional design using convenience sampling was conducted on 400 T2DM patients using Hensarling's Diabetes Family Support Scale and Summary of Diabetes Self‑Care Activities scale. Data analysis was conducted using descriptive, Pearson Moment Product Correlation and Binary Logistic Regression on self-management, social support, and glycemic control in T2DM patients.

Results

Social support among participants was high and there was a positive correlation or relationship between social support and T2DM self-management. There was a correlation between social support and self-management (r = 0.149, p < 0.05) and diet control (r = 0.221, p < 0.05). The results also showed a significant correlation between medication adherence and glycemic management (r = 0.116, p < 0.05) while female T2DM participants, individuals with at least primary education were less likely to have low self-management relative to T2DM.

Conclusion

Though the level of T2DM self-management was high it does not translate to good glycemic control. Focused health education programs should be incorporated into patients' care plans which will be particularly relevant for patients with T2DM and will contribute to positive physiological and psychological outcomes. Furthermore, a more robust monitoring and follow-up scheme should be scaled up or instituted for patients with T2DM.

Nurse-led self-management education and support programme on self-management behaviour and quality of life among adults with type 2 diabetes: A pilot randomized controlled trial

AIM

This study examined the preliminary effects of a nurse-led self-management education and support programme on the self-management behaviours and quality of life among people with type 2 diabetes in Western Ethiopia.

METHODS

A pilot randomized controlled trial was conducted between January and August 2021. Participants were recruited in the hospital and randomly assigned to the control arm to continue usual care (n = 38) or the intervention arm to receive usual care and the diabetes self-management education and support programme (n = 38) in the community. Self-management behaviours and quality of life were assessed using a 10-item summary of diabetes self-care activity (expanded) scale and a 34-item diabetes quality of life measure, respectively, at baseline and 2 months after follow-up. Generalized estimating equation models were used to examine the preliminary effects of the programme on the outcomes.

RESULTS

Preliminary results indicated that the programme outperformed usual care in self-management practise, with large effect sizes immediately postintervention and at 2 months after the intervention, and quality of life at 2 months after the intervention.

CONCLUSION

A nurse-led diabetes self-management education and support intervention, including the families of people with diabetes, may be an option to boost the self-management practise and quality of life of patients with diabetes.

Incidence and determinants of diabetic ketoacidosis among people with diabetes in Woldiya comprehensive specialized hospital, Ethiopia: a retrospective cohort study

INTRODUCTION

Diabetic ketoacidosis is an acute complication of diabetes mellitus that is characterised by hyperglycemia, acidosis, and ketonuria. Diabetes is the most challenging public health problem in the twenty-first century for both developed and developing countries.

OBJECTIVE

To assess the incidence of Diabetic ketoacidosis and its determinants among adult people with diabetes at an Ethiopian Hospital.

METHOD

An institution-based retrospective cohort study was conducted among 390 adult people with diabetes attending services at Wolida Comprehensive Specialized Hospital. The consecutive sampling method was used to select study participant charts. Data were collected using a checklist prepared from different literature. The data were entered into EPI data version 4.6.0.5 and exported to STATA version 14.0 for further analysis. The Wiebull model was the best fitted model that was selected using the log-likelihood ratio method and the Akakian information criterion. Hazard ratios with their 95% confidence interval and p-value were computed.

RESULT

From the total 405 charts reviewed, 390 adult charts were included for analysis. A total of 121 DKA occurred from 5471 person-months of observation. The overall incidence rate of diabetic ketoacidosis was found to be 2.2 per 100 person-months (95% CI: 1.8- 2.6). Being urban dweller (AHR: 0.59, 95% CI: 0.36-0.99), having no family history of DM (AHR: 0.55, 95%CI: 0.31-0.97), presence of infection (AHR: 2.60, 95%CI = 1.06-6.39), having of any comorbidities (AHR: 4.31, 95% CI: 1.70-10.90), and having poor glycemic control (AHR: 7.45, 95% CI: 3.84-14.47) were significant determinants.

CONCLUSION AND RECOMMENDATIONS

The overall incidence of diabetic ketoacidosis in study area was relatively high. Poor glycemic control, the presence of infection, and comorbidity were determinants of diabetic ketoacidosis. There is a need to have close follow-up of people with diabetes who have comorbidity, infection, and poor glycemic control.

Acceptability, Feasibility, and Effectiveness of a Worksite Intervention to Lower Cardiometabolic Risk in South Africa: Protocol

As an important way to translate cardiovascular disease prevention efforts, worksite intervention programs can be used to effectively facilitate healthy food choices, health education, and social support among employees, in a targeted approach to improve health outcomes and physical activity levels of employees. In this study, the effectiveness of a canteen and a behavioral intervention on cardiometabolic risk among prediabetic and prehypertensive employees at two multinational worksites in South Africa will be measured. This two-arm randomized controlled trial (RCT) will be structured to provide a six-week intervention at two multinational companies spread across eight worksites and will include a canteen and behavioral arm (CB) and a canteen only (CO) arm. Participants who are either prediabetic or prehypertensive will complete the baseline assessments, which will include anthropometry, a demographic and lifestyle survey, the global physical activity questionnaire (GPAQ) and the 24 h food recall. Participants will be randomized into the CO and the canteen and CB intervention groups. The CO group will receive six weeks of canteen intervention [changes to enable a healthy food environment], while the CB group will receive six weeks of canteen intervention along with a behavioral intervention. The behavioral intervention will include an intense six-week lifestyle program aligned to the Diabetes Prevention Program (DPP). This study will assess the added benefit of environmental-level changes aimed at lowering cardiometabolic risk in a low-middle-income country (LMIC) and has the potential for scale-up to other worksites in South Africa and globally.

The effectiveness of diabetes self-management education intervention on glycaemic control and cardiometabolic risk in adults with type 2 diabetes in low- and middle-income countries: A systematic review and meta-analysis

Diabetes mellitus (DM) poses a significant challenge to public health. Effective diabetes self-management education (DSME) interventions may play a pivotal role in the care of people with type 2 diabetes mellitus (T2DM) in low- and middle-income countries (LMICs). A specific up-to-date systematic review is needed to assess the effect of DSME interventions on glycaemic control, cardiometabolic risk, self-management behaviours, and psychosocial well-being among T2DM across LMICs. The MEDLINE, Embase, CINAHL, Global Health, and Cochrane databases were searched on 02 August 2022 and then updated on 10 November 2023 for published randomised controlled trials (RCTs) and quasi-experimental studies. The quality of the studies was assessed, and a random-effect model was used to estimate the pooled effect of diabetes DSME intervention. Heterogeneity (I2) was tested, and subgroup analyses were performed. Egger's regression test and funnel plots were used to examine publication bias. The risk of bias of the included studies was assessed using the Cochrane risk-of-bias tool for randomized trial (RoB 2). The overall assessment of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach. A total of 5893 articles were retrieved, and 44 studies (n = 11838) from 21 LMICs met the inclusion criteria. Compared with standard care, pooled analysis showed that DSME effectively reduced the HbA1c level by 0.64% (95% CI: 0.45% to 0.83%) and 1.27% (95% CI: -0.63% to 3.17%) for RCTs and quasi-experimental design studies, respectively. Further, the findings showed an improvement in cardiometabolic risk reduction, diabetes self-management behaviours, and psychosocial well-being. This review suggests that ongoing support alongside individualised face-to-face intervention delivery is favourable for improving overall T2DM management in LMICs, with a special emphasis on countries in the lowest income group.

Artificial intelligence-supported diabetic retinopathy screening in Tanzania: rationale and design of a randomised controlled trial

INTRODUCTION

Globally, diabetic retinopathy (DR) is a major cause of blindness. Sub-Saharan Africa is projected to see the largest proportionate increase in the number of people living with diabetes over the next two decades. Screening for DR is recommended to prevent sight loss; however, in many low and middle-income countries, because of a lack of specialist eye care staff, current screening services for DR are not optimal. The use of artificial intelligence (AI) for DR screening, which automates the grading of retinal photographs and provides a point-of-screening result, offers an innovative potential solution to improve DR screening in Tanzania.

METHODS AND ANALYSIS

We will test the hypothesis that AI-supported DR screening increases the proportion of persons with true referable DR who attend the central ophthalmology clinic following referral after screening in a single-masked, parallel group, individually randomised controlled trial. Participants (2364) will be randomised (1:1 ratio) to either AI-supported or the standard of care DR screening pathway. Participants allocated to the AI-supported screening pathway will receive their result followed by point-of-screening counselling immediately after retinal image capture. Participants in the standard of care arm will receive their result and counselling by phone once the retinal images have been graded in the usual way (typically after 2-4 weeks). The primary outcome is the proportion of persons with true referable DR attending the central ophthalmology clinic within 8 weeks of screening. Secondary outcomes, by trial arm, include the proportion of persons attending the central ophthalmology clinic out of all those referred, sensitivity and specificity, number of false positive referrals, acceptability and fidelity of AI-supported screening.

ETHICS AND DISSEMINATION

The London School of Hygiene & Tropical Medicine, Kilimanjaro Christian Medical Centre and Tanzanian National Institute of Medical Research ethics committees have approved the trial. The results will be submitted to peer-reviewed journals for publication.

Gestational diabetes mellitus in Cameroon: prevalence, risk factors and screening strategies

Background

The burden of gestational diabetes (GDM) and the optimal screening strategies in African populations are yet to be determined. We assessed the prevalence of GDM and the performance of various screening tests in a Cameroonian population.

Methods

We carried out a cross-sectional study involving the screening of 983 women at 24-28 weeks of pregnancy for GDM using serial tests, including fasting plasma (FPG), random blood glucose (RBG), a 1-hour 50g glucose challenge test (GCT), and standard 2-hour oral glucose tolerance test (OGTT). GDM was defined using the World Health Organization (WHO 1999), International Association of Diabetes and Pregnancy Special Group (IADPSG 2010), and National Institute for Health Care Excellence (NICE 2015) criteria. GDM correlates were assessed using logistic regressions, and c-statistics were used to assess the performance of screening strategies.

Findings

GDM prevalence was 5·9%, 17·7%, and 11·0% using WHO, IADPSG, and NICE criteria, respectively. Previous stillbirth [odds ratio: 3·14, 95%CI: 1·27-7·76)] was the main correlate of GDM. The optimal cut-points to diagnose WHO-defined GDM were 5·9 mmol/L for RPG (c-statistic 0·62) and 7·1 mmol/L for 1-hour 50g GCT (c-statistic 0·76). The same cut-off value for RPG was applicable for IADPSG-diagnosed GDM while the threshold was 6·5 mmol/L (c-statistic 0·61) for NICE-diagnosed GDM. The optimal cut-off of 1-hour 50g GCT was similar for IADPSG and NICE-diagnosed GDM. WHO-defined GDM was always confirmed by another diagnosis strategy while IADPSG and GCT independently identified at least 66·9 and 41·0% of the cases.

Interpretation

GDM is common among Cameroonian women. Effective detection of GDM in under-resourced settings may require simpler algorithms including the initial use of FPG, which could substantially increase screening yield.

Incidence, prevalence, and mortality of type 1 diabetes in children and youth in Burkina Faso 2013-2022

AIM

There are no data on type 1 diabetes (T1D) incidence and prevalence in Burkina Faso. We aimed to determine these in persons aged <25 years (y) since the implementation of Life for a Child (LFAC) program in 2013.

PATIENTS AND METHODS

Data were collected from the prospective program register. Diagnosis of T1D was clinical, based on presentation, abrupt onset of symptomatic hyperglycemia, need for insulin replacement therapy from diagnosis, and no suggestion of other diabetes types.

RESULTS

We diagnosed 312 cases of T1D <25y in 2013-2022. Male-to-female ratio was 1:1. T1D incidence <25y per 100,000 population/year increased from 0.08 (CI 95% 0.07-0.60) in 2013 to 0.34 (CI 95% 0.26-0.45) in 2022 (p=0.002). Incidence <15y/y rose from 0.04 (CI 95% 0.01-0.10) to 0.27 (CI 95% 0.18-0.38) per 100,000/year in 2013 and 2022, respectively (p < 0.002). Prevalence per 100,000 population <25y was 0.27 (CI 95% 0.19-0.37) in 2013 and rose to 1.76 (CI 95% 1.546-1.99) in 2022 (p<0.0001). Mortality rate was 20 (CI 95% 13-29.6) per 1,000-person y.

CONCLUSIONS

There is a low but sharply rising T1D incidence and prevalence rates in children and youth in Burkina Faso since LFAC program implementation. It is very likely this is partly due to improved case detection. Mortality remains substantial.

Consensus on potential interventions for improving glycaemic control among patients with type 2 diabetes in Kinshasa, Democratic Republic of the Congo: a Delphi study

BACKGROUND

Poor glycaemic control is a multifactorial and complex problem with dire clinical and economic implications. In the Democratic Republic of the Congo, recent studies have shown alarming poor control rates. There is no policy framework to guide corrective actions.

OBJECTIVES

To build a consensus on interventions to improve glycaemic control among patients with type 2 diabetes in Kinshasa, Democratic Republic of the Congo.

METHODS

This was a two-round electronic Delphi study involving 31 local and 5 international experts. The experts rated proposed interventions from previous studies on glycaemic control in sub-Saharan Africa and Kinshasa on a 4-Likert scale questionnaire. Additionally, the experts were asked to suggest other recommendations useful for the purpose. The mode, mean and standard deviation of each statement were calculated for each round.

RESULTS

Participants reached consensus in five domains that included 39 statements on how to improve glycaemic control in Kinshasa: strengthening the health system, enhancing the awareness of diabetes, alleviating the financial burden of diabetes, enhancing the adoption of lifestyle modifications, and reducing the proportion of undiagnosed diabetes.

CONCLUSIONS

Improved glycaemic control needs to be considered within the broader framework of managing noncommunicable diseases in a more integrated, coordinated and better financed healthcare system. Further studies are needed to operationalise the interventions identified for successful implementation.

Gaps in the type 2 diabetes care cascade: a national perspective using South Africa's National Health Laboratory Service (NHLS) database

BACKGROUND

Research out of South Africa estimates the total unmet need for care for those with type 2 diabetes mellitus (diabetes) at 80%. We evaluated the care cascade using South Africa's National Health Laboratory Service (NHLS) database and assessed if HIV infection impacts progression through its stages.

METHODS

The cohort includes patients from government facilities with their first glycated hemoglobin A1c (HbA1c) or plasma glucose (fasting (FPG); random (RPG)) measured between January 2012 to March 2015 in the NHLS. Lab-diagnosed diabetes was defined as HbA1c ≥ 6.5%, FPG ≥ 7.0mmol/l, or RPG ≥ 11.1mmol/l. Cascade stages post diagnosis were retention-in-care and glycaemic control (defined as an HbA1c < 7.0% or FPG < 8.0mmol/l or RPG < 10.0mmol/l) over 24-months. We estimated gaps at each stage nationally and by people living with HIV (PLWH) and without (PLWOH).

RESULTS

Of the 373,889 patients tested for diabetes, 43.2% had an HbA1c or blood glucose measure indicating a diabetes diagnosis. Amongst those with lab-diagnosed diabetes, 30.9% were retained-in-care (based on diabetes labs) and 8.7% reached glycaemic control by 24-months. Prevalence of lab-diagnosed diabetes in PLWH was 28.6% versus 47.3% in PLWOH. Among those with lab-diagnosed diabetes, 34.3% of PLWH were retained-in-care versus 30.3% PLWOH. Among people retained-in-care, 33.8% of PLWH reached glycaemic control over 24-months versus 28.6% of PLWOH.

CONCLUSIONS

In our analysis of South Africa's NHLS database, we observed that 70% of patients diagnosed with diabetes did not maintain in consistent diabetes care, with fewer than 10% reaching glycemic control within 24 months. We noted a disparity in diabetes prevalence between PLWH and PLWOH, potentially linked to different screening methods. These differences underscore the intricacies in care but also emphasize how HIV care practices could guide better management of chronic diseases like diabetes. Our results underscore the imperative for specialized strategies to bolster diabetes care in South Africa.

Facilitators and barriers to integration of noncommunicable diseases with HIV care at primary health care in Ethiopia: a qualitative analysis using CFIR

Background

The rise in non-communicable diseases (NCD), such as hypertension and diabetes among people living with human immunodeficiency virus (PLWH), has increased the demand for integrated care due to multiple chronic care needs. However, there is a dearth of evidence on contextual factors implementing integrated hypertension and diabetes care with HIV care. This study aimed to identify facilitators and barriers that could affect the integration of hypertension and diabetes with HIV care at primary health care in Ethiopia.

Methods

Five primary health facilities from five districts of the Wolaita zone of South Ethiopia were included in the qualitative study. Fifteen key informant interviews were conducted with healthcare providers and managers from the zonal, district, and facility levels from October to November 2022. Data collection and analysis were guided by a consolidated framework of implementation research (CFIR).

Results

Ten CFIR constructs were found to influence the integration. Perceived benefit of integration to patients, healthcare providers, and organization; perceived possibilities of integration implementation; availability of NCD guidelines and strategies; a supportive policy of decentralization and integration; perceived leaders and healthcare provider commitment were found to be facilitators. Perceived increased cost, insufficient attention to NCD care needs, inadequate number of trained professionals, inadequate equipment and apparatus such as blood pressure measurement, glucometers, strips, and NCD drugs, inadequate allocation of budget and weak health financing system and poor culture of data capturing and reporting were identified as barriers to integration.

Conclusion

It is important to address contextual barriers through innovative implementation science solutions to address multiple chronic care needs of PLWH by implementing integrated hypertension and diabetes with HIV care in primary healthcare. Training and task shifting, pairing experienced professionals, and strengthening the health care financing system to implement evidence-based integration of hypertension and diabetes are recommended.

Type 2 diabetes in the Democratic Republic of Congo: an urgent need for a management framework

Glycaemic control is of one the main goals for managing type 2 diabetes. In sub-Saharan Africa and the Democratic Republic of the Congo, studies have reported alarming poor control rates. Patients with poor glycaemic control are exposed to complications leading to high cost of care and deteriorated quality of life. In recent studies by our group, we have demonstrated that poor glycaemic control is high and driven by proximal (individual) and distal (structural) factors in Kinshasa, Democratic Republic of the Congo. Financial constraints impacted many aspects of care at multiple levels from the Government to persons living with diabetes. Financial constraints prevented good preparation, organization and access to diabetes care. Difficulties in implementing lifestyle changes, lack of health literacy and limited healthcare support were also contributing to poor glycaemic control. Through a Delphi study, a group of experts reached a consensus on five potential strategies for improving glycaemic control in the Democratic Republic of Congo as follows: changing the healthcare system for better diabetes care extended to other noncommunicable diseases, ensuring consistent financing of the healthcare, augmenting the awareness of diabetes among the general population and the persons living with diabetes, easing the adoption of lifestyle modifications and reducing the burden of undiagnosed diabetes. This paper reflects on the urgent need for an improved management framework for diabetes care in the Democratic Republic of the Congo. Specifically, the Government needs to increase the investment in the prevention and treatment of noncommunicable diseases including diabetes.

Effects of family-based diabetes self-management education and support programme on support behaviour amongst adults with type 2 diabetes in Western Ethiopia

Support from family and peers may enhance the outcomes of diabetes management. This study reported the preliminary effect of a family-based diabetes self-management education and support (DSMES) programme on the perceived support status of people with diabetes and the family's caregiver support behaviour amongst dyads living in Western Ethiopia. A 1:1 two-armed pilot randomised controlled trial (RCT) was conducted. A total of 76 dyads were recruited using the convenience sampling method and randomly assigned to either intervention or control groups. The control group continued the usual care, whereas the intervention group continued the usual care and additionally received a 12-h social cognitive theory (SCT)-guided, family-supported DSMES programme in the community. Generalised estimating equations models were computed to test the preliminary effects of the DSMES programme on the outcomes. P-value < 0.05 was set as statistically significant. The pilot RCT shows a statistically significant between-group difference in the changes in support needed at T1 (d = 0.88) and T2 (d = 1.35) and support received at T1 (d = 0.88) and T2 (d = 1.44). The DSMES programme has outperformed usual care with a medium effect size at T1 (d = 0.54) and a large effect size at T2 (d = 0.97) on the family's supportive behaviour. Although the intervention group was not statistically significant at T1 (d = 0.43), a large effect size was obtained at T2 (d = 0.97) on the family's non-supportive behaviour. A SCT-guided, family-supported DSMES programme produced a promising positive effect on enhancing the support needed and support received from their family/friends, and it also improved the family's supportive behaviour. Thus, family support could be incorporated into DSMES programmes for diabetes management in Western Ethiopia. The trial was registered by the Chinese Clinical Trial Registry ( http://www.chictr.org.cn ); Registration number: ChiCTR2000040292.

Prevalence and associated factors of prediabetes in adult East African population: A systematic review and meta-analysis

Introduction

Diabetes mellitus is a major public health problem with serious consequences, and more than three-fourths of diabetes live in low- and middle-income countries. According to a recent study, people with prediabetes have nearly six times the risk of developing diabetes than those with normal glucose levels. However, due to the inconsistency and absence of representative data, this study aimed to estimate the prevalence of prediabetes and its associated factors in the adult East African population.

Methods

Databases were systematically searched for articles published between January 1, 2013, and December 30, 2022. All observational community-based studies that reported prediabetes prevalence and/or associated factors in adult East African populations were included in the meta-analyses. Three authors independently extracted all required data using the Excel data extraction format and analyzed using Stata™ Version 11. An I2 test was conducted to determine significant heterogeneity. Finally, a random effects model was used to determine the overall prevalence of prediabetes and its associated factors. The study was registered with Prospero number CRD42023389745.

Results

The search strategy identified 267 articles. After screening for full-text review, twenty-one articles were included in the final analysis. The overall prevalence of prediabetes was 12.58 % (95 % CI:10.30, 14.86 %) in the adult East African population. Furthermore, the subgroup analysis revealed that prediabetes in the urban population 20 % (95 % CI: 1.60, 38.37) was twice as prevalent as in rural 10.0 % (95 % CI: 5.52, 14.48) populations. The prevalence of prediabetes by the ADA diagnostic criteria was 21.45 % (95 % CI: 15.54, 27.35) three times higher than the WHO 7.20 % (95 % CI: 5.70, 8.69). Moreover, prediabetes was significantly associated with old age (OR = 1.64, 95 %, CI: 1.07, 2.53), hypertension (OR = 2.43, 95 %, CI: 1.02-5.79), obesity and overweight (OR = 1.70, 95 %, CI: 1.09,2.65).

Conclusion

This study showed a high prevalence of prediabetes, which was significantly associated with old age, hypertension, and high BMI. This study suggests that health policymakers should pay attention to the prevention and control strategies that is targeted at those with obesity, hypertension, and old age.

Global variation in diabetes diagnosis and prevalence based on fasting glucose and hemoglobin A1c

Fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) are both used to diagnose diabetes, but these measurements can identify different people as having diabetes. We used data from 117 population-based studies and quantified, in different world regions, the prevalence of diagnosed diabetes, and whether those who were previously undiagnosed and detected as having diabetes in survey screening, had elevated FPG, HbA1c or both. We developed prediction equations for estimating the probability that a person without previously diagnosed diabetes, and at a specific level of FPG, had elevated HbA1c, and vice versa. The age-standardized proportion of diabetes that was previously undiagnosed and detected in survey screening ranged from 30% in the high-income western region to 66% in south Asia. Among those with screen-detected diabetes with either test, the age-standardized proportion who had elevated levels of both FPG and HbA1c was 29-39% across regions; the remainder had discordant elevation of FPG or HbA1c. In most low- and middle-income regions, isolated elevated HbA1c was more common than isolated elevated FPG. In these regions, the use of FPG alone may delay diabetes diagnosis and underestimate diabetes prevalence. Our prediction equations help allocate finite resources for measuring HbA1c to reduce the global shortfall in diabetes diagnosis and surveillance.

Community-based type 2 diabetes care by lay village health workers in rural Lesotho: protocol for a cluster-randomized trial within the ComBaCaL cohort study (ComBaCaL T2D TwiC)

BACKGROUND

Type 2 diabetes (T2D) poses a growing public health burden, especially in low- and middle-income countries (LMICs). Task-shifting to lay village health workers (VHWs) and the use of digital clinical decision support systems (CDSS) are promising approaches to tackle the current T2D care gap in LMICs. However, evidence on the effectiveness of lay worker-led T2D care models, in which VHWs initiate and monitor drug treatment in addition to community-based screening and referral services, is lacking.

METHODS

We are conducting a cluster-randomized trial nested within the Community-Based Chronic Disease Care Lesotho (ComBaCaL) cohort study (NCT05596773) using the trial within cohort (TwiC) design to assess the effectiveness of a VHW-led, CDSS-assisted T2D care model in rural Lesotho. Participants are non-pregnant members of the ComBaCaL cohort study with T2D. The ComBaCaL cohort study is conducted in approximately 100 villages in two rural districts in Lesotho and is managed by trained and supervised VHWs. In intervention villages, VHWs offer a community-based T2D care package including lifestyle counselling, first-line oral antidiabetic, lipid-lowering, and antiplatelet treatment guided by a tablet-based CDSS to participants who are clinically eligible, as well as treatment support to participants who prefer or clinically require facility-based T2D care. In control clusters, all participants will be referred to a health facility for T2D management. The primary endpoint is the mean glycosylated haemoglobin (HbA1c) 12 months after enrolment. Secondary endpoints include the 10-year risk for cardiovascular events estimated using the World Health Organization risk prediction tool.

DISCUSSION

The trial was launched on May 13, 2023, and has enrolled 226 participants at the date of submission (October 6, 2023). To our knowledge, the trial is the first to assess task-shifting of T2D care to VHWs at the community level, including the prescription of first-line antidiabetic, lipid-lowering, and antiplatelet medication in sub-Saharan Africa, and will thus provide the missing evidence on the effectiveness of such a T2D care model in this setting. The study is operating within the established Lesotho VHW programme. Similar community health worker programmes which exist across sub-Saharan Africa may benefit from the findings.

Management of chronic conditions in resource limited settings: multi stakeholders' perception and experiences with receiving and providing integrated HIV, diabetes and hypertension services in Tanzania

BACKGROUND

The rising prevalence of non-communicable diseases (NCDs) alongside the continuing high burden of HIV poses a serious challenge to middle- and low-income countries' healthcare systems. Pilot studies of integrated models of service delivery for HIV, hypertension and diabetes have demonstrated that they are feasible and acceptable among patients and care providers. This study assessed multi-stakeholders' perspectives of the delivery and receipt of integrated care in Tanzania.

METHODS

A qualitative process evaluation was conducted in Dar es Salaam region of Tanzania where the integrated service delivery model was implemented from July to November 2021. In-depth interviews were held with seven key informants at the national, regional and district levels, eight healthcare providers, two researchers working at the integrated clinic and forty patients benefiting from integrated services at a large hospital. Three focus group discussions were held with community leaders and residents of the hospital's catchment area, and clinic level observations were conducted. Thematic analysis was conducted followed by the use of Bronfenbrenner's ecological model to identify factors pertinent to sustaining and scaling up of the integrated model.

RESULTS

Participants of the study at all levels were aware of the increased prevalence of NCDs specifically for hypertension and diabetes and were concerned about the trend of increasing co-morbid conditions among people living with HIV (PLHIV). The integrated service delivery model was positively perceived by stakeholders because of its multiple benefits for both patients and the healthcare system. These include stigma and discrimination reduction, improved quality of care, efficient use of limited resources, cost and time saving, reduced duplication of services and fostering of early detection for undiagnosed conditions. The organisation of the clinic was critical in increased satisfaction. Several challenges were observed, which included costs for NCD services relative to free care for HIV and inconsistent availability of NCD medications.

CONCLUSION

Stakeholders reported numerous benefits of the integrated service delivery model that are fundamental in improving the health of many Tanzanians living with NCDs and HIV. These benefits highlight the need for policy and decision-makers to sustain and expand the integrated service delivery model as a solution to many challenges facing the health system especially at the primary care level.

The association between plasma zinc concentrations and markers of glucose metabolism in adults in Cameroon

An abnormal Zn status has been suggested to play a role in the pathogenesis of type 2 diabetes. However, epidemiological studies of the relationship between plasma Zn concentrations and diabetes are sparse and inconclusive. We aimed to investigate the association between plasma Zn concentrations and glycaemic markers (fasting glucose, 2-h glucose and homeostatic model assessment of insulin resistance) in rural and urban Cameroon. We studied 596 healthy adults (63·3 % women) aged 25-55 years in a population-based cross-sectional study. The mean plasma Zn concentration was 13·7 ± 2·7 µmol/L overall, with higher levels in men (14·4 ± 2·9 µmol/l) than in women (13·2 ± 2·6 µmol/l), P-value < 0·0001. There was an inverse relationship between tertiles of plasma Zn and 2-h glucose concentrations (P-value for linear trend = 0·002). The difference in 2-h glucose between those in the highest tertile of plasma Zn compared to the lowest was -0·63 (95 % CI - 1·02, -0·23) mmol/l. This remained significant after adjusting for age, sex, smoking status, alcohol intake, education level, area of residence, adiposity and objectively measured physical activity -0·43(-0·82, -0·04). Similar inverse associations were observed between plasma Zn concentrations and fasting glucose and homeostatic model assessment of insulin resistance when adjusted for socio-demographic and health-related behavioural characteristics. The current findings of an inverse association between plasma Zn concentrations and several markers of glucose homeostasis, together with growing evidence from intervention studies, suggest a role for Zn in glucose metabolism. If supported by further evidence, strategies to improve Zn status in populations may provide a cheap public health prevention approach for diabetes.

The cost of adding rapid screening for diabetes, hypertension, and COVID-19 to COVID-19 vaccination queues in Johannesburg, South Africa

Background

Non-communicable diseases (NCDs) are responsible for 51% of total mortality in South Africa, with a rising burden of hypertension (HTN) and diabetes mellitus (DM). Incorporating NCD and COVID-19 screening into mass activities such as COVID-19 vaccination programs could offer significant long-term benefits for early detection interventions. However, there is limited knowledge of the associated costs and resources required. We evaluated the cost of integrating NCD screening and COVID-19 antigen rapid diagnostic testing (Ag-RDT) into a COVID-19 vaccination program.

Methods

We conducted a prospective cost analysis at three public sector primary healthcare clinics and one academic hospital in Johannesburg, South Africa, conducting vaccinations. Participants were assessed for eligibility and recruited during May-Dec 2022. Costs were estimated from the provider perspective using a bottom-up micro-costing approach and reported in 2022 USD.

Results

Of the 1,376 enrolled participants, 240 opted in to undergo a COVID-19 Ag-RDT, and none tested positive for COVID-19. 138 (10.1%) had elevated blood pressure, with 96 (70%) having no prior HTN diagnosis. 22 (1.6%) were screen-positive for DM, with 12 (55%) having no prior diagnosis. The mean and median costs per person screened for NCDs were $2.53 (SD: 3.62) and $1.70 (IQR: $1.38-$2.49), respectively. The average provider cost per person found to have elevated blood glucose levels and blood pressure was $157.99 and $25.19, respectively. Finding a new case of DM and HTN was $289.65 and $36.21, respectively. For DM and DM + HTN screen-positive participants, diagnostic tests were the main cost driver, while staff costs were the main cost driver for - and HTN screen-positive and screen-negative participants. The mean and median cost per Ag-RDT was $6.13 (SD: 0.87) and $5.95 (IQR: $5.55-$6.25), with costs driven mainly by test kit costs.

Conclusions

We show the cost of finding new cases of DM and HTN in a vaccine queue, which is an essential first step in understanding the feasibility and resource requirements for such initiatives. However, there is a need for comparative economic analyses that include linkage to care and retention data to fully understand this cost and determine whether opportunistic screening should be added to general mass health activities.

Integrated management of HIV, diabetes, and hypertension in sub-Saharan Africa (INTE-AFRICA): a pragmatic cluster-randomised, controlled trial

BACKGROUND

In sub-Saharan Africa, health-care provision for chronic conditions is fragmented. The aim of this study was to determine whether integrated management of HIV, diabetes, and hypertension led to improved rates of retention in care for people with diabetes or hypertension without adversely affecting rates of HIV viral suppression among people with HIV when compared to standard vertical care in medium and large health facilities in Uganda and Tanzania.

METHODS

In INTE-AFRICA, a pragmatic cluster-randomised, controlled trial, we randomly allocated primary health-care facilities in Uganda and Tanzania to provide either integrated care or standard care for HIV, diabetes, and hypertension. Random allocation (1:1) was stratified by location, infrastructure level, and by country, with a permuted block randomisation method. In the integrated care group, participants with HIV, diabetes, or hypertension were managed by the same health-care workers, used the same pharmacy, had similarly designed medical records, shared the same registration and waiting areas, and had an integrated laboratory service. In the standard care group, these services were delivered vertically for each condition. Patients were eligible to join the trial if they were living with confirmed HIV, diabetes, or hypertension, were aged 18 years or older, were living within the catchment population area of the health facility, and were likely to remain in the catchment population for 6 months. The coprimary outcomes, retention in care (attending a clinic within the last 6 months of study follow-up) for participants with either diabetes or hypertension (tested for superiority) and plasma viral load suppression for those with HIV (>1000 copies per mL; tested for non-inferiority, 10% margin), were analysed using generalised estimating equations in the intention-to-treat population. This trial is registered with ISCRTN 43896688.

FINDINGS

Between June 30, 2020, and April 1, 2021 we randomly allocated 32 health facilities (17 in Uganda and 15 in Tanzania) with 7028 eligible participants to the integrated care or the standard care groups. Among participants with diabetes, hypertension, or both, 2298 (75·8%) of 3032 were female and 734 (24·2%) of 3032 were male. Of participants with HIV alone, 2365 (70·3%) of 3365 were female and 1000 (29·7%) of 3365 were male. Follow-up lasted for 12 months. Among participants with diabetes, hypertension, or both, the proportion alive and retained in care at study end was 1254 (89·0%) of 1409 in integrated care and 1457 (89·8%) of 1623 in standard care. The risk differences were -0·65% (95% CI -5·76 to 4·46; p=0·80) unadjusted and -0·60% (-5·46 to 4·26; p=0·81) adjusted. Among participants with HIV, the proportion who had a plasma viral load of less than 1000 copies per mL was 1412 (97·0%) of 1456 in integrated care and 1451 (97·3%) of 1491 in standard care. The differences were -0·37% (one-sided 95% CI -1·99 to 1·26; pnon-inferiority<0·0001 unadjusted) and -0·36% (-1·99 to 1·28; pnon-inferiority<0·0001 adjusted).

INTERPRETATION

In sub-Saharan Africa, integrated chronic care services could achieve a high standard of care for people with diabetes or hypertension without adversely affecting outcomes for people with HIV.

The T1D Index: Implications of Initial Results, Data Limitations, and Future Development

PURPOSE OF THE REVIEW

Current global information on incidence, prevalence, and mortality of type 1 diabetes (T1D) is limited, particularly in low- and middle-income countries. To address this gap in evidence, JDRF, Life for a Child, International Society for Pediatric and Adolescent Diabetes, and International Diabetes Federation have developed the T1D Index, which uses a Markov mathematical model, and machine learning and all available data to provide global estimates of the burden on T1D. This review assesses the methodology, limitations, current findings, and future directions of the Index.

RECENT FINDINGS

Global prevalence was estimated at 8.4 million in 2021, with 1.5 million <20 years (y). T1D prevalence varied from 1.5 to 534 per 100,000, with T1D accounting for <0.1-17.8% of all diabetes in different countries. A total of 35,000 young people <25 y are estimated to have died at clinical onset of T1D from non-diagnosis. An estimated 435,000 people <25 y were receiving "minimal care." Health-adjusted life years (HALYs) lost for individuals diagnosed with T1D at age 10 y in 2021 ranged from 14 to 55 y. These results show that interventions to reduce deaths from non-diagnosis, and improve access to at least an intermediate care level, are needed to reduce projected life years lost. The results have significant uncertainties due to incomplete data across the required inputs. Obtaining recent incidence, prevalence, and mortality data, as well as addressing data quality issues, misdiagnoses, and the lack of adult data, is essential for maintaining and improving accuracy. The index will be updated regularly as new data become available.

Diabetes care and education training audit for primary care physicians across 47 counties of Kenya: A pre-post intervention study

INTRODUCTION

The purpose of the study was to evaluate the effectiveness of an online continuous medical education programme for Primary Care Physicians (PCPs) in improving diabetes management in Kenya.

METHODS

A pretest-post-test design was used to assess the change in knowledge across multiple modules and the overall change in the confidence level of the PCPs in managing people living with diabetes. The study was non-randomised. Course participants were nominated by local scientific associations.

RESULTS

Out of a total of 1750 nominated participants, 1286 completed the training. A statistically significant (p=<0.001) change in knowledge and overall confidence was observed for each of the 8 modules of the training programme. Cohen's D effect size was calculated as 2.20 and 1.40 for change in knowledge and confidence levels, respectively.

DISCUSSION

Web-based training is an effective way to improve the knowledge and self-reported confidence of PCPs involved in the management of diabetes. This web-based model can support the training needs of PCPs at a pace and time to suit their situation. Similar evidence-based programmes should be considered and field-tested for other healthcare professionals working in the management of diabetes.

Metformin for the prevention of diabetes among people with HIV and either impaired fasting glucose or impaired glucose tolerance (prediabetes) in Tanzania: a Phase II randomised placebo-controlled trial

AIMS/HYPOTHESIS

In sub-Saharan Africa (SSA), 5% of adults are living with type 2 diabetes and this is rising sharply, with a greater increase among people with HIV. Evidence on the efficacy of prevention strategies in this cohort is scarce. We conducted a Phase II double-blind placebo-controlled trial that aimed to determine the impact of metformin on blood glucose levels among people with prediabetes (defined as impaired fasting glucose [IFG] and/or impaired glucose tolerance [IGT]) and HIV in SSA.

METHODS

Adults (≥18 years old) who were stable in HIV care and found to have prediabetes (IFG and/or IGT) and who were attending hospitals in Dar es Salaam, Tanzania, were randomised to receive sustained-release metformin, 2000 mg daily, or matching placebo between 4 November 2019 and 21 July 2020. Randomisation used permuted blocks. Allocation was concealed in the trial database and made visible only to the Chief Pharmacist after consent was taken. All participants, research and clinical staff remained blinded to the allocation. Participants were provided with information on diet and lifestyle and had access to various health information following the start of the coronavirus disease 2019 (COVID-19) pandemic. Participants were followed up for 12 months. The primary outcome measure was capillary blood glucose measured 2 h following a 75 g glucose load. Analyses were by intention-to-treat.

RESULTS

In total, 364 participants (182 in each arm) were randomised to the metformin or placebo group. At enrolment, in the metformin and placebo arms, mean fasting glucose was 6.37 mmol/l (95% CI 6.23, 6.50) and 6.26 mmol/l (95% CI 6.15, 6.36), respectively, and mean 2 h glucose levels following a 75 g oral glucose load were 8.39 mmol/l (95% CI 8.22, 8.56) and 8.24 mmol/l (95% CI 8.07, 8.41), respectively. At the final assessment at 12 months, 145/182 (79.7%) individuals randomised to metformin compared with 158/182 (86.8%) randomised to placebo indicated that they had taken >95% of their medicines in the previous 28 days (p=0.068). At this visit, in the metformin and placebo arms, mean fasting glucose levels were 6.17 mmol/l (95% CI 6.03, 6.30) and 6.30 mmol/l (95% CI 6.18, 6.42), respectively, and mean 2 h glucose levels following a 75 g oral glucose load were 7.88 mmol/l (95% CI 7.65, 8.12) and 7.71 mmol/l (95% CI 7.49, 7.94), respectively. Using a linear mixed model controlling for respective baseline values, the mean difference between the metformin and placebo group (metformin-placebo) was -0.08 mmol/l (95% CI -0.37, 0.20) for fasting glucose and 0.20 mmol/l (95% CI -0.17, 0.58) for glucose levels 2 h post a 75 g glucose load. Weight was significantly lower in the metformin arm than in the placebo arm: using the linear mixed model adjusting for baseline values, the mean difference in weight was -1.47 kg (95% CI -2.58, -0.35). In total, 16/182 (8.8%) individuals had a serious adverse event (Grade 3 or Grade 4 in the Division of Acquired Immunodeficiency Syndrome [DAIDS] adverse event grading table) or died in the metformin arm compared with 18/182 (9.9%) in the placebo arm; these events were either unrelated to or unlikely to be related to the study drugs.

CONCLUSIONS/INTERPRETATION

Blood glucose decreased over time in both the metformin and placebo arms during the trial but did not differ significantly between the arms at 12 months of follow up. Metformin therapy was found to be safe for use in individuals with HIV and prediabetes. A larger trial with longer follow up is needed to establish if metformin can be safely used for the prevention of diabetes in people who have HIV.

'The solution is we need to have a centre': a study on diabetes in Liberia

In Liberia, one of the poorest nations in sub-Saharan Africa, the burden of diabetes is a growing concern. The high mortality and morbidity associated with diabetes have significant implications for individuals, families and society at large. The aim of this critical hermeneutic study was to explore what it is like to live with diabetes in Liberia. We recruited 10 participants from Monrovia, Liberia to partake in this study. Photovoice, a well-established participatory data collection approach was used to gather images and stories that represented participants' everyday experiences of living with diabetes. Three major themes were uncovered, highlighting the strengths, challenges and solutions related to living with diabetes in Liberia: strengths-engagement in diabetes self-management practices, focused on participants' commitment to engage in diabetes self-management practices despite the socioeconomic challenges they experienced; challenges-lack of social and economic support, focused on limited access to food, diabetes medications and supplies and diabetes education; and solutions-centre for diabetes education, care and support, focused on participants' recommendations for a community-based diabetes centre, a single point of access for meeting the needs of people with diabetes. A strong commitment to prioritize diabetes on Liberia's national health agenda and increased resources for diabetes care is needed to address the challenges experienced by people living with this chronic disease in Liberia.

Health service readiness to provide care for HIV and cardiovascular disease risk factors in low- and middle-income countries

Cardiovascular disease risk factors (CVDRF), in particular diabetes and hypertension, are chronic conditions which carry a substantial disease burden in Low- and Middle-Income Countries. Unlike HIV, they were neglected in the Millenium Development Goals along with the health services required to manage them. To inform the level of health service readiness that could be achieved with increased attention, we compared readiness for CVDRF with that for HIV. Using data from national Service Provision Assessments, we describe facility-reported readiness to provide services for CVDRF and HIV, and derive a facility readiness score of observed essential components to manage them. We compared HIV vs CVDRF coverage scores by country, rural or urban location, and facility type, and by whether or not facilities reported readiness to provide care. We assessed the factors associated with coverage scores for CVDRF and HIV in a multivariable analysis. In our results, we include 7522 facilities in 8 countries; 86% of all facilities reported readiness to provide services for CVDRF, ranging from 77-98% in individual countries. For HIV, 30% reported of facilities readiness to provide services, ranging from 3-63%. Median derived facility readiness score for CVDRF was 0.28 (IQR 0.16-0.50), and for HIV was 0.43 (0.32-0.60). Among facilities which reported readiness, this rose to 0.34 (IQR 0.18-0.52) for CVD and 0.68 (0.56-0.76) for HIV. Derived readiness scores were generally significantly lower for CVDRF than for HIV, except in private facilities. In multivariable analysis, odds of a higher readiness score in both CVDRF or HIV care were higher in urban vs rural and secondary vs primary care; facilities with higher CVDRF scores were significantly associated with higher HIV scores. Derived readiness scores for HIV are higher than for CVDRF, and coverage for CVDRF is significantly higher in facilities with higher HIV readiness scores. This suggests possible benefits from leveraging HIV services to provide care for CVDRF, but poor coverage in rural and primary care facilities threatens Sustainable Development Goal 3.8 to provide high quality universal healthcare for all.

Identification and characterisation of diabetes in Uganda: protocol for the nested, population-based 'Diabetes in low-resource Populations' (DOP) Study

INTRODUCTION

Sub-Saharan Africa is experiencing an increasing burden of diabetes, but there are little reliable data, particularly at the community level, on the true prevalence or why this condition affects young and relatively lean individuals. Moreover, the detection of diabetes in Africa remains poor, not only due to a lack of resources but because the performance of available diagnostic tests is unclear.

METHODS

This research aims to (1) determine the prevalence and risk factors of diabetes in a rural Ugandan population, (2) use clinical and biochemical markers to define different diabetes phenotypes and (3) study the progression of diabetes in this population. We will also assess the utility of the widely used tests (glycated haemoglobin (HbA1c), oral glucose tolerance test (OGTT) and fasting glucose) in diagnosing diabetes.

DESIGN

This is a population-based study nested within the longstanding general population cohort in southwestern Uganda. We will undertake a population survey to identify individuals with diabetes based on fasting glucose, HbA1c, OGTT results or history of pre-existing diabetes.

PARTICIPANTS

The study intends to enrol up to 11 700 individuals aged 18 years and above, residing within the study area and not pregnant or within 6 months post-delivery date. All participants will have detailed biophysical and biochemical/metabolic measurements. Individuals identified to have diabetes and a random selection of controls will have repeat tests to test reproducibility before referral and enrolment into a diabetic clinic. Participants will then be followed up for 1 year to assess the course of the disease, including response to therapy and diabetes-related complications.

CONCLUSIONS

These data will improve our understanding of the burden of diabetes in Uganda, the risk factors that drive it and underlying pathophysiological mechanisms, as well as better ways to detect this condition. This will inform new approaches to improve the prevention and management of diabetes.

Associations between physical activity patterns and quality of life in persons with type 2 diabetes: A cross sectional study

BACKGROUND

Type 2 diabetes is a major health problem globally and particularly in Ghana. Regular physical activity is important in the management of type 2 diabetes and in improving quality of life of persons with type 2 diabetes. However, there is a lack of data reporting on how physical activity relate to quality of life in persons with diabetes in Ghana. This study explored how physical activity patterns relate to quality of life in persons with type 2 diabetes from a major tertiary hospital in Ghana.

METHODS

One hundred and twenty-one (121) persons with type 2 diabetes (age, 30-60 years) filled in questionnaires on their physical activity patterns (time spent in sitting, walking, moderate-intensity activities, and vigorous-intensity activities) and quality of life (diabetes control, anxiety and worry, social burden, sexual functioning, energy and mobility). The relationships between the variables were examined using spearman correlation.

RESULTS

Time spent in sitting, walking, moderate-intensity activities and vigorous-intensity activities were 1677.7±401.5min, 464.1±296.0MET-min, 241.2±65.8MET-min and 1956.5±1251.0MET-min respectively. Walking was negatively related to energy and mobility (r = -.48, p<0.01), sexual functioning (r = -0.44, p<0.01), social burden (r = -0.41, p<0.01) and diabetes control (r = -0.56, p<0.01) domains of quality of life. Vigorous-intensity activities was negatively related to anxiety and worry (r = -0.20, p<0.05).

CONCLUSIONS

The results suggests that persons with type 2 diabetes who experience decline in energy and mobility, sexual functioning, and disease management, and heightened social burden, anxiety and worry may benefit from guidance on optimal physical activity behaviour in the form of walking to improve their quality of life.

In-Hospital Mortality Outcomes of ST-Segment Elevation Myocardial Infarction: A Cross-Sectional Study from a Tertiary Academic Hospital in Johannesburg, South Africa

In sub-Saharan Africa, the burden of atherosclerotic cardiovascular disease (ASCVD) is increasing. This study aimed to describe the clinical characteristics of patients with ST-segment elevation myocardial infarction (STEMI) and estimate the in-hospital all-cause mortality rate. We conducted a cross-sectional retrospective single-centre study of STEMI patients who underwent diagnostic coronary angiography with or without percutaneous coronary intervention (PCI) between January 2015 and December 2019. We compared demographic and clinical parameters between survivors and non-survivors with descriptive statistics. Univariable and multivariable logistic regression analyses were performed to determine the predictors of all-cause mortality. The study population consisted of 677 patients with a mean age of 55.5 ± 11.3 years. The in-hospital all-cause mortality rate was 6.2% [95% confidence interval (CI): 4.5-8.3%]. Risk factors for ASCVD included smoking (56.1%), hypertension (52.8%), dyslipidemia (40.0%), and a family history of coronary artery disease (32.7%). A pharmaco-invasive management strategy (treatment with thrombolytic therapy and PCI) was implemented in 36.5% of patients and reduced all-cause mortality risk (OR: 0.16; CI: 0.04-0.71, p = 0.015). The in-hospital all-cause mortality rate in STEMI patients was 6.2%, and a pharmaco-invasive management strategy proved to be an effective approach.

Statistical analysis plan and protocol updates for Gestational diabetes in Uganda and India: Design and Evaluation of Educational Films for Improving Screening and Self-management (GUIDES) trial

BACKGROUND

Timely detection and management of gestational diabetes mellitus (GDM) have been identified as a high priority for policymakers in low- and middle-income countries (LMICs). The GUIDES trial will evaluate a package of three interconnected film-based interventions aimed at improving the timely detection and management of GDM. The protocol for this trial has previously been published; this publication outlines the statistical analysis plan for the trial.

METHODS AND DESIGN

The GUIDES study is a multi-country cluster-randomised controlled trial consisting of one trial conducted in Uganda and one in India (30 clusters in each country). Mixed effects models will be used to compare the primary study outcomes of the proportion of women who are tested for GDM between 24 and 32 weeks of pregnancy and the mean fasting blood sugar of women with GDM at 34-week follow-up while accounting for clustering. Secondary analyses will compare the proportion of women with self-reported GDM diagnosis at 32 weeks of pregnancy and the proportion of women with adverse perinatal outcomes related to GDM up to 4 weeks after birth in each trial arm.

TRIAL STATUS AND DISCUSSION

Follow-up is expected to end in March 2023 in Uganda and in May 2023 in India. Analyses will be carried out following this statistical analysis plan in the month following trial completion.

Exploring the Relation Between Diabetes and HIV: A Narrative Review

Diabetes mellitus, more usually abbreviated as DM or just diabetes, is a devastating metabolic disorder that claims many lives every year. Due to various variables, including the aging of the HIV (human immunodeficiency virus)-infected population and the high prevalence of chronic medical conditions among persons living with HIV, the crossroads of DM and HIV infection has become a significant research topic. Although the connection between HIV and diabetes is not simple, many aspects of the virus and its treatment have been connected to the onset of diabetes. The presence of inconclusive evidence that HIV is a risk factor for diabetes makes this area more challenging and debatable. This article examines the prevalence of DM in the HIV-positive community, along with its assessment, management, and treatment objectives. The most recent diabetes treatment recommendations from authoritative groups are considered in this article to give readers thorough and current advice. These guidelines emphasize the importance of tailoring pharmacological therapy and treatment goals to suit the specific needs of individuals with diabetes, including those who are also living with HIV. Individualizing treatment plans ensures that healthcare professionals consider comorbidities, medication interactions, and potential side effects when managing diabetes concerning HIV. In the later part of the article, a holistic approach is discussed to address the increased risk of cardiovascular disease and associated complications in HIV-positive individuals with diabetes. This approach aims to mitigate cardiovascular risks and improve overall health outcomes through comprehensive strategies such as lifestyle modifications, regular monitoring, medication management, and integration of multidisciplinary healthcare teams. By considering the unique challenges and considerations of individuals living with both HIV and diabetes, healthcare providers can develop targeted interventions and provide optimal care. In order to improve the life and health of persons living with HIV and diabetes, the article stresses the significance of cooperation amongst professionals in these fields.

Prevalence of diabetes foot ulcers and associated factors among adult diabetic patients in three referral hospitals in Mogadishu, Somalia

Background

Diabetes mellitus (DM) causes significant morbidity and mortality in sub-Saharan Africa (SSA), including Somalia. Among diabetic patients, diabetic foot ulcers (DFUs) constitute the largest proportion of admissions, amputations, and mortality. The aim of this study is to assess the prevalence of diabetic foot ulcers and subsequently determine factors associated with it among diabetic patients at three major hospitals in Somalia.

Methods

An institutional-based cross-sectional study was conducted among 193 diabetic patients between August and November 2022. All eligible diabetes patients who were attending De Martini Hospital, Madina General Hospital, and Deynile General Hospital during the study period were included in the study. Patients were interviewed using a structured questionnaire. We collected demographic, clinical, and behavioral variables from all participants. A bivariate and multivariable logistic regression model was fitted to identify factors associated with diabetic foot ulcer. An odds ratio with a 95% confidence interval was computed to determine the level of significance.

Result

The mean age of the study's participants was 50.9 ± 13.6 years. The prevalence of diabetic foot ulcer was 15%. Patients who were either overweight or obese (OR 4.63, CI: 2.08-10.30), had a lack of family support in managing diabetes (OR 3.33, CI: 1.74-6.36), and did not check their feet regularly were more likely to develop DFU (OR 1.99, CI:1.08-3.66).

Conclusion

Increased body mass index, lack of family support, and not checking feet regularly were associated with DFUs. The high prevalence of DFUs and the plethora of needs of people with DFUs pose challenges for health care. A coordinated health care system is necessary to meet the needs of diabetic patients and prevent DFUs.

Scaling up integrated care for HIV and other chronic conditions in routine health care settings in sub-Saharan Africa: Field notes from Uganda

Introduction

Integration of HIV and non-communicable disease (NCD) services is proposed to increase efficiency and coverage of NCD care in sub-Saharan Africa.

Description

Between October 2018 to January 2020 in Tanzania and Uganda, working in partnership with health services, we introduced an integrated chronic care model for people with HIV, diabetes and hypertension. In this model, patients were able to access care from a single point of care, as opposed to the standard of siloed care from vertical clinics. When the study ended, routine clinical services adopted the integrated model. In this article, we discuss how the model transitioned post hand-over in Uganda and draw lessons to inform future scale-up.

Discussion

The findings suggest potential for successful uptake of integrated chronic care by routine clinical services in sub-Saharan Africa. This approach may appeal to health care service providers and policy makers when they can quantify benefits that accrue from it, such as optimal utilization of health resources. For patients, integrated care may not appeal to all patients due to HIV-related stigma. Key considerations include good communication with patients, strong leadership, maintaining patient confidentiality and incorporating patient needs to facilitate successful uptake.

Conclusion

Evidence on the benefits of integrated care remains limited. More robust evidence will be essential to guide scale-up beyond research sites.

Time to Diabetic Nephropathy and its Predictors Among Diabetic Patients Treated in Wolaita and Dawuro Zone Hospitals, Ethiopia: A Retrospective Cohort Study

Background

Diabetic kidney disease (DKD) develops in nearly half of patients with type 2 diabetes mellitus (DM) and one-third of those with type 1 DM during their lifetime. The incidence of DKD as a cause of end stage renal disease is increasing each year. So this study aimed to assess the time to develop diabetic nephropathy and predictors among diabetic patients treated in Wolaita zone hospitals.

Methodology

A ten-year retrospective cohort study had conducted among 614 diabetic patients using systematic random sampling in Wolaita and Dawuro zone hospitals. Bivariable and multivariable Cox proportional hazards regression had used to identify the possible associations between variables. Those variables with a p-value of less than 0.25 in bivariable analysis exported to multivariable Cox regression analysis. Finally, variables with p-value less than 0.05 at multivariable Cox regression were considered significantly significant. The Cox-proportional hazard model assumption had checked using the Schoenfeld residual test.

Results

Of the total participants, 93 (15.3%; 95% CI = 12.45-18.14) patients had developed nephropathy in 820,048 people year observation. A mean time to diabetic nephropathy in this study was 189.63 (95% CI, 185.01, 194.25) months. Being illiterate (AHR: 2.21, 95% CI: 1.34-3.66), being hypertensive (AHR: 5.76, 95% CI: 3.39-9.59), and being urban dwellers (AHR: 2.25, 95% CI: 1.34-3.77) increases the hazard of nephropathy.

Conclusion

According to this follow-up study, the overall incidence rate is substantially high over ten year follow-up period. The mean time to develop diabetic nephropathy was sixteen years. Educational status, place of residence, and being hypertensive were the predictors. So stakeholders should work on complication reduction measures and awareness creation of the impact of comorbidities.

Living with type 1 diabetes in Neno, Malawi: a qualitative study of self-management and experiences in care

BACKGROUND

The prevalence of type 1 diabetes (T1D) is increasing in low-income countries including Malawi. In this setting, care is frequently impacted by challenges in diagnosis and management. Access to high-quality T1D care remains limited in Malawi, with fairly low availability and high cost of insulin and other supplies and diagnostics, lack of T1D knowledge, and absence of readily accessible guidelines. In the Neno district, Partners In Health established advanced care clinics at district hospitals to provide comprehensive, free care for T1D and other noncommunicable diseases. Prior to this study, experiences in care for people living with T1D (PLWT1D) at these clinics remained unexplored. Here we examine the impact of living with T1D, knowledge and self-management of, and facilitators and barriers to T1D care in Neno District, Malawi.

METHODS

We conducted a qualitative study utilizing behavior change theory that consisted of twenty-three semi-structured interviews conducted in Neno, Malawi in January 2021 with PLWT1D, their families, providers, and civil society members to explore the psychosocial and economic impact of living with T1D, T1D knowledge and self-management, and facilitators and barriers to accessing care. Interviews were analyzed thematically using a deductive approach.

RESULTS

We found that PLWT1D had good knowledge and practice of self-management activities for T1D. Key facilitators to care identified by informants included extensive patient education and availability and provision of free insulin and supplies. Significant barriers included distance from health facilities, food insecurity, and low literacy/numeracy. Informants described T1D as having a notable psychosocial and economic impact on PWLT1D and their families, notably worrying about having a lifelong condition, high transportation costs, and reduced working ability. While home visits and transport refunds helped facilitate access to the clinic, informants reported the refunds as inadequate given high transport costs faced by patients.

CONCLUSIONS

T1D was found to have a significant impact on PLWT1D and their families. Our findings represent important areas of consideration in design and implementation of effective programs for treating PLWT1D in resource-limited settings. Facilitators to care identified by informants may be applicable and beneficial in similar settings, while persisting barriers represent areas for continued improvement in Neno.

Implementing integrated care clinics for HIV-infection, diabetes and hypertension in Uganda (INTE-AFRICA): process evaluation of a cluster randomised controlled trial

BACKGROUND

Sub-Saharan Africa is experiencing a dual burden of chronic human immunodeficiency virus and non-communicable diseases. A pragmatic parallel arm cluster randomised trial (INTE-AFRICA) scaled up 'one-stop' integrated care clinics for HIV-infection, diabetes and hypertension at selected facilities in Uganda. These clinics operated integrated health education and concurrent management of HIV, hypertension and diabetes. A process evaluation (PE) aimed to explore the experiences, attitudes and practices of a wide variety of stakeholders during implementation and to develop an understanding of the impact of broader structural and contextual factors on the process of service integration.

METHODS

The PE was conducted in one integrated care clinic, and consisted of 48 in-depth interviews with stakeholders (patients, healthcare providers, policy-makers, international organisation, and clinical researchers); three focus group discussions with community leaders and members (n = 15); and 8 h of clinic-based observation. An inductive analytical approach collected and analysed the data using the Empirical Phenomenological Psychological five-step method. Bronfenbrenner's ecological framework was subsequently used to conceptualise integrated care across multiple contextual levels (macro, meso, micro).

RESULTS

Four main themes emerged; Implementing the integrated care model within healthcare facilities enhances detection of NCDs and comprehensive co-morbid care; Challenges of NCD drug supply chains; HIV stigma reduction over time, and Health education talks as a mechanism for change. Positive aspects of integrated care centred on the avoidance of duplication of care processes; increased capacity for screening, diagnosis and treatment of previously undiagnosed comorbid conditions; and broadening of skills of health workers to manage multiple conditions. Patients were motivated to continue receiving integrated care, despite frequent NCD drug stock-outs; and development of peer initiatives to purchase NCD drugs. Initial concerns about potential disruption of HIV care were overcome, leading to staff motivation to continue delivering integrated care.

CONCLUSIONS

Implementing integrated care has the potential to sustainably reduce duplication of services, improve retention in care and treatment adherence for co/multi-morbid patients, encourage knowledge-sharing between patients and providers, and reduce HIV stigma.

Perceptions of multiple chronic conditions and coping strategies among migrants from Sub-Saharan Africa living in France with diabetes mellitus and HIV: An interview-based qualitative study

Although diabetes is common among people living with HIV/AIDS (PLWHA), few data exists on how migrants from Sub-Saharan Africa (SSA) experience living with these two coexisting conditions in France. The objective of this study was to analyze perception of polypathology among PLWHA from SSA with type 2 diabetes and identify barriers and facilitators to their self-management. A qualitative study was conducted using semi-structured interviews from November 2019 to April 2020 with participants selected from a cohort of PLWHA and diabetes at Avicenne University Hospital. A total of 12 semi-structured interviews were conducted and analyzed using thematic analysis with inductive approach. Stigma remained a major issue in self-managing HIV, and some participants did not consider themselves as having a polypathology, as HIV has always been considered as a distinct condition. In general, emotion-based resources (e.g spirituality, trust in the medical discourse) and social support were mobilized more than problem-solving resources (e.g perception of medication as life-saving). Participants used the same main resource in self-management of HIV and diabetes, and resources used differed from participant to participant. This study highlighted challenges in self-management of diabetes and HIV in this population and complexity related to the socioeconomic and cultural specificities. Self-management could be more successful if patients and carers move in the same direction, having identified the individual coping resources to reach objectives.

Intervention development of 'Diabetes Together' using the person-based approach: a couples-focused intervention to support self-management of type 2 diabetes in South Africa

OBJECTIVES

Type 2 diabetes (T2D) is a growing concern in South Africa, where many find self-management challenging. Behaviour-change health interventions are enhanced by involving partners of patients. We aimed to develop a couples-focused intervention to improve self-management of T2D among adults in South Africa.

DESIGN

We used the person-based approach (PBA): synthesising evidence from existing interventions; background research; theory; and primary qualitative interviews with 10 couples to ascertain barriers and facilitators to self-management. This evidence was used to formulate guiding principles that directed the intervention design. We then prototyped the intervention workshop material, shared it with our public and patient involvement group and ran iterative co-discovery think-aloud sessions with nine couples. Feedback was rapidly analysed and changes formulated to improve the intervention, optimising its acceptability and maximising its potential efficacy.

SETTING

We recruited couples using public-sector health services in the area of Cape Town, South Africa, during 2020-2021.

PARTICIPANTS

The 38 participants were couples where one person had T2D.

INTERVENTION

We developed the 'Diabetes Together' intervention to support self-management of T2D among couples in South Africa, focussing on: improved communication and shared appraisal of T2D; identifying opportunities for better self-management; and support from partners. Diabetes Together combined eight informational and two skills-building sections over two workshops.

RESULTS

Our guiding principles included: providing equal information on T2D to partners; improving couples' communication; shared goal-setting; discussion of diabetes fears; discussing couples' roles in diabetes self-management; and supporting couples' autonomy to identify and prioritise diabetes self-management strategies.Participants viewing Diabetes Together valued the couples-focus of the intervention, especially communication. Feedback resulted in several improvements throughout the intervention, for example, addressing health concerns and tailoring to the setting.

CONCLUSIONS

Using the PBA, our intervention was developed and tailored to our target audience. Our next step is to pilot the workshops' feasibility and acceptability.

Carpe DM: The First Global Diabetes Targets

The authors discuss the newly adopted global diabetes targets and their potential role in driving funding, advocacy, research, and clinical care to reduce the massive global disparities in access to quality diabetes care.
