BackgroundThe obesity epidemic is associated with rising rates of cardiovascular disease (CVD) among adults, particularly in countries undergoing rapid urbanisation and nutrition transition. This study explored the perceptions of body size, obesity risk awareness, and the willingness to lose weight among adults in a resource-limited urban community to inform appropriate community-based interventions for the prevention of obesity.MethodThis is a descriptive qualitative study. Semi-structured focus group discussions were conducted with purposively selected black men and women aged 35–70 years living in an urban South African township. Weight and height measurements were taken, and the participants were classified into optimal weight, overweight and obese groups based on their body mass index (Kg/m2). Participants were asked to discuss on perceived obesity threat and risk of cardiovascular disease. Information on body image perceptions and the willingness to lose excess body weight were also discussed. Discussions were conducted in the local language (isiXhosa), transcribed and translated into English. Data was analysed using the thematic analysis approach.ResultsParticipants generally believed that obesity could lead to health conditions such as heart attack, stroke, diabetes, and hypertension. However, severity of obesity was perceived differently in the groups. Men in all groups and women in the obese and optimal weight groups perceived obesity to be a serious threat to their health, whereas the overweight women did not. Obese participants who had experienced chronic disease conditions indicated strong perceptions of risk of obesity and cardiovascular disease. Obese participants, particularly men, expressed willingness to lose weight, compared to the men and women who were overweight. The belief that overweight is ‘normal’ and not a disease, subjective norms, and inaccessibility to physical activity facilities, negatively influenced participants’ readiness to lose weight.ConclusionLow perception of threat of obesity to health particularly among overweight women in this community indicates a considerable challenge to obesity control. Community health education and promotion programmes that increase awareness about the risk associated with overweight, and improve the motivation for physical activity and maintenance of optimal body weight are needed.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-016-3028-7) contains supplementary material, which is available to authorized users.

An estimated 2 million foreign-born migrants of working age (15-64) were living in South Africa (SA) in 2017. Structural and practical xenophobia has driven asylum-seekers, refugees, and undocumented migrants in SA to abject poverty and misery. The Coronavirus Disease 2019 (COVID-19) containment measures adopted by the SA government through the lockdown of the nation have tremendously deepened the unequal treatment of asylumseekers and refugees in SA. This can be seen through the South African government's lack of consideration of this marginalized population in economic, poverty, and hunger alleviation schemes. Leaving this category of our society out of the national response safety nets may lead to negative coping strategies causing mental health issues and secondary health concerns. An effective response to the socioeconomic challenges imposed by the COVID-19 pandemic should consider the economic and health impact of the pandemic on asylum-seekers, refugees, and undocumented migrants.

Realist evaluation submits that theories and models of how, why, for whom and under what circumstances programs work could be formulated by conceptualizing the relational links between the context within which programs are implemented, the generative mechanisms the programs trigger, and the outcomes of interest. Qualitative and quantitative data collection and analysis allow for the description of the relevant context, the generative mechanisms, and the emergent outcomes of programs and provide explanatory power to link these elements. The ‘realist interviewing technique’, whereby interviewees comment on a suggested ‘program theory’ to provide refinement, is proposed as a distinctive approach for conducting interviews in a realist-informed inquiry. However, the application of this interviewing strategy within the realist evaluation studies is underutilized. In this study, we demonstrate how the realist interview technique reinforces and maintains theoretical awareness and contributes to trustworthiness through three theory-building phases: theory gleaning, theory refining, and theory consolidation.

BackgroundSouth Africa currently runs the largest public antiretroviral treatment (ART) programme in the world, with over 80% of people living with HIV and/or AIDS on ART. However, in order to appreciate the benefits of using ART, patients are subject to uncompromising and long-term commitments of taking at least 95% of their treatment as prescribed. Evidence shows that this level of adherence is seldom achieved because of a multilevel and sometimes interwoven myriad of factors.ObjectiveWe described the challenges faced by patients on ART in Vredenburg with regard to ART adherence.MethodsA descriptive qualitative research design was used. Eighteen non-adhering patients on ART in the Vredenburg regional hospital were purposefully selected. Using a semi-structured interview guide, we conducted in-depth interviews with the study participants in their mother tongue (Afrikaans). The interviews were audio-taped, transcribed verbatim and translated into English. The data were analysed manually using the thematic content analysis method.ResultsStigma, disclosure, unemployment, lack of transport, insufficient feeding, disability grants and alternative forms of therapy were identified as major barriers to adherence, whereas inadequate follow-ups and lack of patient confidentiality came under major criticisms from the patients.ConclusionInterventions to address poverty, stigma, discrimination and disclosure should be integrated with group-based ART adherence models in Vredenburg while further quantitative investigations should be carried out to quantify the extent to which these factors impede adherence in the community.

IntroductionSuboptimal retention in care and poor treatment adherence are key challenges to antiretroviral therapy (ART) in sub-Saharan Africa. Community-based approaches to HIV service delivery are recommended to improve patient retention in care and ART adherence. The implementation of the adherence clubs in the Western Cape province of South Africa was with variable success in terms of implementation and outcomes. The need for operational guidelines for its implementation has been identified. Therefore, understanding the contexts and mechanisms for successful implementation of the adherence clubs is crucial to inform the roll-out to the rest of South Africa. The protocol outlines an evaluation of adherence club intervention in selected primary healthcare facilities in the metropolitan area of the Western Cape Province, using the realist approach.Methods and analysisIn the first phase, an exploratory study design will be used. Document review and key informant interviews will be used to elicit the programme theory. In phase two, a multiple case study design will be used to describe the adherence clubs in five contrastive sites. Semistructured interviews will be conducted with purposively selected programme implementers and members of the clubs to assess the context and mechanisms of the adherence clubs. For the programme's primary outcomes, a longitudinal retrospective cohort analysis will be conducted using routine patient data. Data analysis will involve classifying emerging themes using the context-mechanism-outcome (CMO) configuration, and refining the primary CMO configurations to conjectured CMO configurations. Finally, we will compare the conjectured CMO configurations from the cases with the initial programme theory. The final CMOs obtained will be translated into middle range theories.Ethics and disseminationThe study will be conducted according to the principles of the declaration of Helsinki (1964). Ethics clearance was obtained from the University of the Western Cape. Dissemination will be done through publications and curation.

Background. HIV remains a major public health challenge in Zambia. The roll-out of antiretroviral treatment (ART) has engendered new challenges in retention in care. Objective. To conceptualise the factors affecting retention in care of ART patients at three primary healthcare facilities using the ecological framework. Method. Qualitative data were collected through in-depth interviews with 45 ART patients and three focus group discussions with 20 healthcare providers from three primary healthcare facilities in Kabwe district, Zambia, and subjected to thematic content analysis. Results. Individual level barriers to retention in care included side effects, gaining weight, belief in faith healing, and use of herbal remedies and alcohol. Interpersonal barriers such as stigma and nondisclosure of HIV status were reported. At the institutional level, inadequate space in the clinic, long waiting times, long travel distances, and shortage of third-line drugs presented barriers to retention in care. Food shortages and patient mobility were reported as community barriers to retention in care. Conclusion. The ecological framework conceptualises the complex and dynamic factors affecting retention in ART care and highlights the need for multifaceted interventions that combine health education, disease management, and opportunities for income generation in a socially responsive and accountable environment.

BackgroundThe antiretroviral adherence club intervention was rolled out in primary health care facilities in the Western Cape province of South Africa to relieve clinic congestion, and improve retention in care, and treatment adherence in the face of growing patient loads. We adopted the realist evaluation approach to evaluate what aspects of antiretroviral club intervention works, for what sections of the patient population, and under which community and health systems contexts, to inform guidelines for scaling up of the intervention. In this article, we report on a step towards the development of a programme theory—the assumptions of programme designers and health service managers with regard to how and why the adherence club intervention is expected to achieve its goals and perceptions on how it has done so (or not).MethodsWe adopted an exploratory qualitative research design. We conducted a document review of 12 documents on the design and implementation of the adherence club intervention, and key informant interviews with 12 purposively selected programme designers and managers. Thematic content analysis was used to identify themes attributed to the programme actors, context, mechanisms, and outcomes. Using the context-mechanism-outcome configurational tool, we provided an explanatory focus of how the adherence club intervention is roll-out and works guided by the realist perspective.ResultsWe classified the assumptions of the adherence club designers and managers into the rollout, implementation, and utilisation of the adherence club programme, constructed around the providers, management/operational staff, and patients, respectively. Two rival theories were identified at the patient-perspective level. We used these perspectives to develop an initial programme theory of the adherence club intervention, which will be tested in a later phase.ConclusionThe perspectives of the programme designers and managers provided an important step towards developing an initial programme theory, which will guide our realist evaluation of the adherence club programme in South Africa.

BackgroundThe successful initiation of people living with HIV/AIDS on antiretroviral therapy (ART) in South Africa has engendered challenges of poor retention in care and suboptimal adherence to medication. The adherence club intervention was implemented in the Metropolitan area of the Western Cape Province to address these challenges. The adherence club programme has shown potential to relieve clinic congestion, improve retention in care and enhance treatment adherence in the context of rapidly growing HIV patient populations being initiated on ART. Nevertheless, how and why the adherence club intervention works is not clearly understood. We aimed to elicit an initial programme theory as the first phase of the realist evaluation of the adherence club intervention in the Western Cape Province.MethodsThe realist evaluation approach guided the elicitation study. First, information was obtained from an exploratory qualitative study of programme designers’ and managers’ assumptions of the intervention. Second, a document review of the design, rollout, implementation and outcome of the adherence clubs followed. Third, a systematic review of available studies on group-based ART adherence support models in Sub-Saharan Africa was done, and finally, a scoping review of social, cognitive and behavioural theories that have been applied to explain adherence to ART. We used the realist evaluation heuristic tool (Intervention-context-actors-mechanism-outcome) to synthesise information from the sources into a configurational map. The configurational mapping, alignment of a specific combination of attributes, was based on the generative causality logic – retroduction.ResultsWe identified two alternative theories: The first theory supposes that patients become encouraged, empowered and motivated, through the adherence club intervention to remain in care and adhere to the treatment. The second theory suggests that stable patients on ART are being nudged through club rules and regulations to remain in care and adhere to the treatment with the goal to decongest the primary health care facilities.ConclusionThe initial programme theory describes how (dynamics) and why (theories) the adherence club intervention is expected to work. By testing theories in “real intervention cases” using the realist evaluation approach, the theories can be modified, refuted and/or reconstructed to elicit a refined theory of how and why the adherence club intervention works.Electronic supplementary materialThe online version of this article (10.1186/s12874-018-0503-0) contains supplementary material, which is available to authorized users.
