- Type 2 diabetes (T2D) and its complications are increasing rapidly in low- and middle-income countries, as well as among socioeconomically disadvantaged populations in high-income countries. Support for healthy lifestyle and self-management is paramount but not well implemented in health systems, and there is need for knowledge on how to design and implement interventions that are contextualized and patient centered and address special needs of disadvantaged population groups. The SMART2D project implements and evaluates a lifestyle and self-management intervention for participants recently diagnosed with or being at increased risk for T2D in rural communities in Uganda, an urban township in South Africa, and socioeconomically disadvantaged urban communities in Sweden. Our aim was to develop an intervention with shared key functions and a good fit with the local context, needs, and resources. The intervention program design was conducted in three steps facilitated by a coordinating team: (a) situational analysis based on the SMART2D Self-Management Framework and definition of intervention objectives and core strategies; (b) designing generic tools for the strategies; and (c) contextual translation of the generic tools and their delivery. This article focuses on community strategies to strengthen support from the social and physical environment and to link health care and community support. Situational analyses showed that objectives and key functions addressing mediators from the SMART2D framework could be shared. Generic tools ensured retaining of functions, while content and delivery were highly contextualized. Phased, collaborative approach and theoretical framework ensured that key functions were not lost in contextualization, also allowing for cross-comparison despite flexibility with other aspects of the intervention between the sites.

Tidskriftsartikel (refereegranskat)abstract
- The burden of type 2 diabetes is increasing rapidly, not least in Sub-Saharan Africa, and disadvantaged populations are disproportionally affected. Self-management is a key strategy for people at risk of or with type 2 diabetes, but implementation is a challenge. The objective of this study is to assess the determinants of self-management from an implementation perspective in three settings: two rural districts in Uganda, an urban township in South Africa, and socio-economically disadvantaged suburbs in Sweden. Data collection followed an exploratory multiple-case study design, integrating data from interviews, focus group discussions, and observations. Data collection and analysis were guided by a contextualized version of a transdisciplinary framework for self-management. Findings indicate that people at risk of or with type 2 diabetes are aware of major self-management strategies, but fail to integrate these into their daily lives. Depending on the setting, opportunities to facilitate implementation of self-management include: improving patient-provider interaction, improving health service delivery, and encouraging community initiatives supporting self-management. Modification of the physical environment (e.g. accessibility to healthy food) and the socio-cultural environment (i.e. norms, values, attitudes, and social support) may have an important influence on people's lifestyle. Regarding the study methodology, we learned that this innovative approach can lead to a comprehensive analysis of self-management determinants across different settings. An important barrier was the difficult contextualization of concepts like perceived autonomy and self-efficacy. Intervention studies are needed to confirm whether the pathways suggested by this study are valid and to test the proposed opportunities for change.

Tidskriftsartikel (refereegranskat)abstract
- Background and objectives To understand the utility of glycated haemoglobin (HBA(1c)) in screening for diabetes and Abnormal Glucose Regulation (AGR) in primary care, we compared its performance to that of the fasting plasma glucose (FPG) test. Methods This was a prospective diagnostic accuracy study conducted in eastern Uganda. Patients eligible for inclusion were consecutive adults, 30-75 years, receiving care at the outpatient department of a general hospital in eastern Uganda. We determined the sensitivity, specificity and optimum cut-off points for HBA(1c) and FPG tests using the oral glucose tolerance test (OGTT) as a clinical reference standard. Results A total of 1659 participants underwent FPG testing of whom 310 were also HBA(1c) and OGTT tested. A total of 113 tested positive for diabetes and 168 for AGR on the OGTT. At recommended cut-off points for diabetes, the HBA(1c) and FPG tests had comparable sensitivity [69.8% (95% CI 46.3-86.1) versus 62.6% (95% CI 41.5-79.8), respectively] and specificity [98.6% (95% CI 95.4-99.6) versus 99.4% (95% CI 98.9-99.7), respectively]. Similarly, the sensitivity of HBA(1c) and the FPG tests for Abnormal Glucose Regulation (AGR) at ADA cut-offs were comparable [58.9% (95% CI 46.7-70.2) vs 47.7% (95% CI 37.3-58.4), respectively]; however, the HBA(1c) test had lower specificity [70.7% (95% CI 65.1-75.8)] than the FPG test [93.5% (95% CI 88.6-96.4)]. At the optimum cut-offs points for diabetes [45.0 mmol/mol (6.3%) for HBA(1c) and 6.4 mmol/L (115.2 mg/dl) for FPG], HBA(1c) and FPG sensitivity [71.2% (95% CI 46.9-87.8) versus 72.7% (95% CI 49.5-87.8), respectively] and specificity [95.1% (95% CI91.8 97.2) versus 98.7% (95% CI 98.0 99.2), respectively] were comparable. Similarly, at the optimum cut-off points for AGR [42.0 mmol/mol (6.0%) for the HBA(1c) and 5.5 mmol/l (99.0 mg/dl) for the FPG test], HBA(1c) and FPG sensitivity [42.3% (95% CI 31.8-53.6) and 53.2 (95% CI 43.1-63.1), respectively] and specificity [89.1% (95% CI 84.1 92.7) and 92.7% (95% CI 91.0 94.1), respectively] were comparable. Discussion HBA(1c) is a viable alternative diabetes screening and confirmatory test to the FPG test; however, the utility of both tests in screening for prediabetes in this outpatient population is limited.

Tidskriftsartikel (refereegranskat)abstract
- Background Type 2 diabetes is rapidly becoming a significant challenge in Uganda and other low and middle-income countries. A large proportion of the population remains undiagnosed. To understand diagnostic delay, we explored the diagnostic pathways for diabetes among patients receiving care at a semi-urban district hospital in eastern Uganda.Methods Eligible participants were patients aged 35-70 years receiving care at the diabetes clinic of Iganga district hospital between April and May 2019 and their healthcare providers. Patients were interviewed using an interview guide to collect information on patients' symptoms and their diagnostic experience. A separate interview guide was used to understand the organisation of the diabetes services and the diabetes diagnostic process at the hospital. Using maximum variation purposive sampling, we selected 17 diabetes patients aged 35-68 years, diagnosed within the previous three years, and the three health workers managing the diabetes clinic at Iganga hospital. The data was analysed using ATLAS.ti version 8 to code, organise and track the data segments. We conducted template analysis using a priori themes derived from the intervals of Walter's model of Pathways to Treatment to identify the factors influencing diagnostic delay.Results We identified four typologies: a short diagnostic pathway, protracted appraisal pathway, protracted appraisal and diagnostic interval pathway, and delayed treatment pathway. The pathways of patients with protracted appraisal or diagnostic intervals demonstrated strong socio-cultural influences. There was a firm reliance on traditional healers both before and after diagnosis which deferred enrolment into care. Other health system barriers implicated in delayed diagnosis included stock-out of diagnostic supplies, misdiagnosis, and missed diagnosis. Denial of diagnosis was also found to lead to delayed initiation of care.Conclusion Reducing diagnostic delay requires addressing both negative socio-cultural influences and the adoption of system-wide interventions to address barriers to timely diagnosis.

- BACKGROUND: The burden of type 2 diabetes in Sub-Saharan Africa is projected to double by 2040, partly attributable to rapidly changing diets. In this paper, we analysed how community members in rural Uganda understood the concept of a healthy or unhealthy diet, food preparation and serving practices to inform the process of facilitating knowledge and skill necessary for self-management and care for type 2 diabetes. This was a qualitative study involving 20 focus group discussions and eight in-depth interviews among those at risk, patients with type 2 diabetes and the general community members without diabetes mellitus. Data was coded and entered into Atlas ti version 7.5.12 and interpreted using thematic analysis. We identified three main themes, which revealed, the perceptions on food and diet concerning health; the social dimensions of food and influence on diet practices; and food as a gendered activity. Participants noted that eating and cooking practices resulted in unhealthy diets. Their practices were affected by beliefs, poverty and food insecurity. Women determined which foods to prepare, but men prepared only some of the foods such as delicacies like a rice dish "pilau." New commercial and processed foods were increasingly available and consumed even in rural areas. Participants linked signs and symptoms of illness to diet as they narrated changes from past to current food preparation behaviours. Their view of overweight and obesity was also gendered and linked to social status. Participants' perception of disease influenced by diet was similar among those with and without type 2 diabetes, and those at risk. People described what is a healthy diet was as recommended by the health workers, but stated that their practices differed greatly from their knowledge. There was high awareness about healthy and balanced diets, but food is entrenched within social and gendered paradigms, which are slowly changing. Social and gender dimensions of food will need to be addressed through interventions in communities to promote change on a society level.

- AimsGlycated haemoglobin (HbA1C) has been suggested to replace glucose tests in identifying diabetes and pre-diabetes. We assessed agreement between fasting plasma glucose (FPG) and HbA1C rapid tests in classifying abnormal glucose regulation (AGR), and their utility for preventive screening in rural Africa.MethodsA population-based survey of 795 people aged 35–60 years was conducted in a mainly rural district in Uganda. FPG was measured using On-Call® Plus glucometers, and classified using World Health Organization (WHO) and American Diabetes Association (ADA) criteria. HbA1C was measured using A1cNow® kits and classified using ADA criteria. Body mass index and blood pressure were measured. Percentage agreement between the two tests was computed.ResultsUsing HbA1C, 11.3% of participants had diabetes compared with 4.8% for FPG. Prevalence of HbA1C-defined pre-diabetes (26.4%) was 1.2 times and 2.5 times higher than FPG-defined pre-diabetes using ADA (21.8%) and WHO (10.1%) criteria, respectively. With FPG as the reference, agreement between FPG and HbA1C in classifying diabetes status was moderate (Kappa = 22.9; Area Under the Curve (AUC) = 75%), while that for AGR was low (Kappa = 11.0; AUC = 59%). However, agreement was high (over 90%) among negative tests and among participants with risk factors for type 2 diabetes (obesity, overweight or hypertension). HbA1C had more procedural challenges than FPG.ConclusionsAlthough low in the general sample, agreement between HbA1C and FPG is excellent among persons who test negative with either test. A single test can therefore identify the majority at lower risk for type 2 diabetes. Nurses if trained can conduct these tests.

Tidskriftsartikel (refereegranskat)abstract
- Background: Our aim was to estimate the prevalence of abnormal glucose regulation (AGR) (i.e. diabetes and prediabetes) and its associated factors among people aged 35-60 years so as to clarify the relevance of targeted screening in rural Africa. Methods: A population-based survey of 1,497 people (786 women and 711 men) aged 35-60 years was conducted in a predominantly rural Demographic Surveillance Site in eastern Uganda. Participants responded to a lifestyle questionnaire, following which their Body Mass Index (BMI) and Blood Pressure (BP) were measured. Fasting plasma glucose (FPG) was measured from capillary blood using On-Call (R) Plus (Acon) rapid glucose meters, following overnight fasting. AGR was defined as FPG >= 6.1 mmol L-1 (World Health Organization (WHO) criteria or >= 5.6mmol L-1 (American Diabetes Association (ADA) criteria. Diabetes was defined as FPG >6.9mmol L-1, or being on diabetes treatment. Results: The mean age of participants was 45 years for men and 44 for women. Prevalence of diabetes was 7.4% (95% CI 6.1-8.8), while prevalence of pre-diabetes was 8.6% (95% CI 7.3-10.2) using WHO criteria and 20.2% (95% CI 17.5-22.9) with ADA criteria. Using WHO cut-offs, the prevalence of AGR was 2 times higher among obese persons compared with normal BMI persons (Adjusted Prevalence Rate Ratio (APRR) 1.9, 95% CI 1.3-2.8). Occupation as a mechanic, achieving the WHO recommended physical activity threshold, and higher dietary diversity were associated with lower likelihood of AGR (APRR 0.6, 95% CI 0.4-0.9; APRR 0.6, 95% CI 0.4-0.8; APRR 0.5, 95% CI 0.3-0.9 respectively). The direct medical cost of detecting one person with AGR was two US dollars with ADA and three point seven dollars with WHO cut-offs. Conclusions: There is a high prevalence of AGR among people aged 35-60 years in this setting. Screening for high risk persons and targeted health education to address obesity, insufficient physical activity and non-diverse diets are necessary.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:Few studies have examined the behavioural correlates of non-communicable, chronic disease risk in low-income countries. The objective of this study was to identify socio-behavioural characteristics associated with being overweight or being hypertensive in a low-income setting, so as to highlight possible interventions and target groups.METHODS:A population based survey was conducted in a Health and Demographic Surveillance Site (HDSS) in eastern Uganda. 1656 individuals aged 35 to 60 years had their Body Mass Index (BMI) and blood pressure (BP) assessed. Seven lifestyle factors were also assessed, using a validated questionnaire. Logistic regression was used to identify socio-behavioural factors associated with being overweight or being hypertensive.RESULTS:Prevalence of overweight was found to be 18% (25.2% of women; 9.7% of men; p<0.001) while prevalence of obesity was 5.3% (8.3% of women; 2.2% of men). The prevalence of hypertension was 20.5%. Factors associated with being overweight included being female (OR 3.7; 95% CI 2.69-5.08), peri-urban residence (OR 2.5; 95% CI 1.46-3.01), higher socio-economic status (OR 4.1; 95% CI 2.40-6.98), and increasing age (OR 1.8; 95% CI 1.12-2.79). Those who met the recommended minimum physical activity level, and those with moderate dietary diversity were less likely to be overweight (OR 0.5; 95% CI 0.35-0.65 and OR 0.7; 95% CI 0.49-3.01). Factors associated with being hypertensive included peri-urban residence (OR 2.4; 95%CI 1.60-3.66), increasing age (OR 4.5; 95% CI 2.94-6.96) and being over-weight (OR 2.8; 95% CI 1.98-3.98). Overweight persons in rural areas were significantly more likely to be hypertensive than those in peri-urban areas (p = 0.013).CONCLUSIONS:Being overweight in low-income settings is associated with sex, physical activity and dietary diversity and being hypertensive is associated with being overweight; these factors are modifiable. There is need for context-specific health education addressing disparities in lifestyles at community levels in rural Africa.

Type 2 diabetes in rural Uganda : prevalence, risk factors, perceptions and implications for the health system
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Between 2010 and 2030, a 69% increase in type-2 diabetes is expected in low-income countries compared to a 20% increase in high income countries. Yet health system responsiveness to non-communicable diseases has been slow in sub-Saharan Africa. Data on the prevalence of type 2 diabetes and its associated factors in mainly rural settings is lacking, yet such data can guide planning for diabetes control. Objective: The aim of these studies was to assess the prevalence of type 2 diabetes, its risk factors, risk perceptions, and possible screening tools among people aged 35-60 years so as to inform primary care level intervention in rural low-income settings. Methods: Four studies (I-IV) were conducted among people aged 35-60 years in a mainly rural demographic surveillance site in eastern Uganda (2011-2013). Study I, a cross-sectional survey assessed the prevalence of diabetes-related risk factors (including overweight, hypertension and seven socio-behavioural risk factors) in 1,656 people. Study II then estimated the prevalence of abnormal glucose regulation (AGR) using fasting plasma glucose (FPG), and assessed its socio-behavioural correlates in 1,497 people. To compare the utility of FPG and glycated haemoglobin (HbA1C) rapid tests in risk stratification, a comparative survey of 795 people was nested into study II (Study III). To assess perceptions about diabetes, 12 Focus Group Discussions were conducted among people afflicted or at higher risk of type 2 diabetes (Study IV). The assessments used standard measurements and cut-offs. Results: About 18% of people aged 35-60 years were overweight, while 21% had hypertension. Women (OR 3.7; 95% CI 2.7-5.1), peri-urban dwellers (OR 2.5; 95% CI 1.5-3.0), and wealthier people (OR 4.1; 95% CI 2.4-7.0) were more likely to be overweight. Only 34% had adequate knowledge about lifestyle diseases (I). Prevalence of diabetes was 7.4% while pre-diabetes was 8.6% and 20.2% with WHO and American Diabetes Association criteria respectively (II). Prevalence of AGR was twice higher in obese people compared to those with a normal BMI (APRR 1.9, 95% CI 1.3-2.8) (II). Sufficient physical activity and diverse diet were associated with lower likelihood of AGR (II). The direct medical cost of screening one person was US$0.53, translating to US$2 per person detected with AGR. Agreement between FPG (the reference) and HbA1C in classifying diabetes was moderate (Kappa=22.9; AUC =75%), while that for AGR was low (Kappa=11.0; AUC=59%) (III). However, agreement was high (over 90%) among negative tests and in participants with risk factors for type 2 diabetes. FPG was more practical than HbA1C (III). Participants‟ strong perceptions of diabetes as a very severe disease were incongruent with their perceived urgency for lifestyle change (IV).While people with diabetes perceive obesity as „sickness‟, those without diabetes say it signifies „success‟ (IV). Poverty, access to food and large families were cited as barriers to healthy diets. Domestic work was the preferred platform for physical activity increments. Conclusions: Obesity, insufficient physical activity and unhealthy diets are possible aids to identifying people at higher risk of type 2 diabetes in primary care. Mass screening for abnormal glucose regulation may not be affordable to struggling health systems. However, rapid tests have utility in further evaluation of people with risk factors. Health education about lifestyle diseases is a priority and should target to change the community‟s notion of health and healthy lifestyles. Several challenges of adding NCD services to overstretched health systems come to light.

Process evaluation of a pragmatic implementation trial to support self-management for the prevention and management of type 2 diabetes in Uganda, South Africa and Sweden in the SMART2D project
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Type 2 diabetes (T2D) and its complications are increasing rapidly. Support for healthy lifestyle and self-management is paramount, but not adequately implemented in health systems. Process evaluations facilitate understanding why and how interventions work through analyzing the interaction between intervention theory, implementation and context. The Self-Management and Reciprocal Learning for Type 2 Diabetes project implemented and evaluated community-based interventions (peer support program; care companion; and link between facility care and community support) for persons at high risk of or having T2D in a rural community in Uganda, an urban township in South Africa, and socioeconomically disadvantaged urban communities in Sweden.Research design and methods: This paper reports implementation process outcomes across the three sites, guided by the Medical Research Council framework for complex intervention process evaluations. Data were collected through observations of peer support group meetings using a structured guide, and semistructured interviews with project managers, implementers, and participants.Results: The countries aligned implementation in accordance with the feasibility and relevance in the local context. In Uganda and Sweden, the implementation focused on peer support; in South Africa, it focused on the care companion part. The community-facility link received the least attention. Continuous capacity building received a lot of attention, but intervention reach, dose delivered, and fidelity varied substantially. Intervention-related and context-related barriers affected participation.Conclusions: Identification of the key uncertainties and conditions facilitates focus and efficient use of resources in process evaluations, and context relevant findings. The use of an overarching framework allows to collect cross-contextual evidence and flexibility in evaluation design to adapt to the complex nature of the intervention. When designing interventions, it is crucial to consider aspects of the implementing organization or structure, its absorptive capacity, and to thoroughly assess and discuss implementation feasibility, capacity and organizational context with the implementation team and recipients. These recommendations are important for implementation and scale-up of complex interventions.
