Digital food ordering platforms are used by millions across the world and provide easy access to takeaway fast-food that is broadly, though not exclusively, characterised as energy dense and nutrient poor. Outlets are routinely rated for hygiene, but not for their healthiness. Nutritional information is mandatory in pre-packaged foods, with many companies voluntarily using traffic light labels to support making healthier choices. We wanted to identify a feasible universal method to objectively score takeaway fast-food outlets listed on Just Eat that could provide users with an accessible rating that can infer an outlet’s ‘healthiness’. Using a sample of takeaway outlets listed on Just Eat, we obtained four complete assessments by nutrition researchers of each outlet’s healthiness to create a cumulative score that ranged from 4 to 12. We then identified and manually extracted nutritional attributes from each outlet’s digital menu, e.g., number of vegetables that have the potential to be numerated. Using generalized linear modelling we identified which attributes were linear predictors of an outlet’s healthiness assessment from nutritional researchers. The availability of water, salad, and the diversity of vegetables were positively associated with academic researchers’ assessment of an outlet’s healthiness, whereas the availability of chips, desserts, and multiple meal sizes were negatively associated. This study shows promise for the feasibility of an objective measure of healthiness that could be applied to all outlet listings on Just Eat and other digital food outlet aggregation platforms. However, further research is required to assess the metric’s validity, its desirability and value to users, and ultimately its potential influence on food choice behaviour.

Introduction Maternity waiting homes (MWHs) link pregnant women to skilled birth attendance at health facilities. Research suggests that some MWH-facility birth interventions are more success at meeting the needs and expectations of their intended users than others. We aimed to develop theory regarding what resources work to support uptake and scale-up of MHW-facility birth interventions, how, for whom, in what contexts and why. Methods A four-step realist review was conducted which included development of an initial programme theory; searches for evidence; selection, appraisal and extraction of data; and analysis and data synthesis. Results A programme theory was developed from 106 secondary sources and 12 primary interviews with MWH implementers. The theory demonstrated that uptake and scale-up of the MWH-facility birth intervention depends on complex interactions between three adopter groups: health system stakeholders, community gatekeepers and pregnant women and their families. It describes relationships between 19 contexts, 11 mechanisms and 31 outcomes accross nine context-mechanism-outcome configurations (CMOCs) which were grouped into 3 themes: (1) Engaging stakeholders to develop, integrate, and sustain MWH-facility birth interventions, (2) Promoting and enabling MWH-facility birth utilisation and (3) Creating positive and memorable MWH-facility birth user experiences. Belief, trust, empowerment, health literacy and perceptions of safety, comfort and dignity were mechanisms that supported diffusion and adoption of the intervention within communities and health systems. Examples of resources provided by implementers to trigger mechanisms associated with each CMOC were identified. Conclusions Implementers of MWHs cannot merely assume that communities will collectively value an MWH-facility birth experience over delivery at home. We posit that MWH-facility birth interventions become vulnerable to under-utilisation when implementers fail to: (1) remove barriers that hinder women’s access to MWH and (2) ensure that conditions and interactions experienced within the MWH and its affiliated health facility support women to feel treated with compassion, dignity and respect.

Despite growing evidence of the significance of health literacy in managing and coping with acquired immune deficiency syndrome (HIV), it is not yet an integrated part of HIV/AIDS-related health promotion research and practice in Africa. This article contributes to addressing the gap in research on health literacy and HIV in Sub-Saharan Africa. We aimed to assess health literacy-related needs of young people living with HIV (YPLHIV) and adapt existing health literacy frameworks to the context of HIV/AIDS in Malawi. We used focus group discussions to collect data from a sample of the membership of the national association of YPLHIV. Twenty-four HIV-positive youth (18–29 years) participated in focus group discussions. Participants came from three regions of Malawi. Additionally, we conducted three in-depth interviews with key informants. We used a thematic framework approach to analyse data in MAXQDA. We contextualized definitions of four dimensions of health literacy: functional, interactive, critical and distributed health literacy, which we used as an a priori analytical framework. To further contextualize the framework, we revised it iteratively throughout the analysis process. We identified the need for comprehensive information about HIV and sexual reproductive health, skills to interact with healthcare providers and navigate the health system, and skills to appraise information from different sources, among others. The identified needs were translated into nine action recommendations for the national association of YPLHIV, and with relevance within the wider HIV sector in Malawi and beyond. We found that the dimensions in our analytical framework operate on the individual, system and public policy levels.

Introduction This is a study protocol that tests and refines realist theories regarding the uptake and scale-up of the linked maternity waiting home (hereafter MWH) and facility birth intervention in the Mozambican context. The theories were developed through a realist review of MWH–facility birth literature from low-income and middle-income countries. The aim of the proposed study is to contribute to a contextually refined understanding of the causal chains underlying MWH–facility birth adoption by pregnant women and their families, communities, the health system and donors. Methods and analysis The overarching methodology is mixed-methods realist evaluation. The study will adopt a comparative embedded case study design comparing three new masonry MWHs built by the Mozambique-Canada Maternal Health Project in Inhambane province with three older MWHs selected based on variation in the built environment. Baseline data on participating MWH–facility birth interventions will be collected through observations, reviews of routine data and analysis of statistics and reports from provincial and district health authorities and the Mozambique-Canada Maternal Health project. Realist interviews will be conducted with MWH users and non-users, companions of MWH users and non-users, partners of MWH users and non-users, and stakeholders within the health system and the non-governmental organisation sector. Realist focus groups will be used to collect data from community-level implementers. The analysis will be retroductive and use the context–mechanism–outcome configuration heuristic tool to represent generative causation. We will analyse data from intervention and comparator MWHs independently and compare the resulting refined programme theories. Data analysis will be done in NVivo 12. Ethics and dissemination Ethics approval for the project has been obtained from the Mozambique National Bioethics Committee (CNBS-Comité Nacional de Bioética para a Saúde) and the University of Saskatchewan Bioethical Research Ethics Board. The evaluation will adhere to the International Ethical Guidelines for Biomedical Research Involving Human Subjects and the African adaptation of evaluation ethics and principles. Evaluation results will be disseminated to stakeholders' practice audiences through peer-reviewed publications, plain-language briefs, theory validation/feedback meetings and conference presentations.

Introduction Hypertensive disorders of pregnancy, such as pre-eclampsia (PE), are one of the leading causes of maternal and perinatal deaths in low- and middle-income countries (LMICs). Although clinical practice guidelines (CPGs) for PE prevention and management are available, there is limited information on their implementation in LMIC contexts. This realist synthesis therefore aims to uncover the causal explanations underpinning the implementation of CPG recommendations for PE prevention and management in Eastern, Central and Southern African contexts. By developing and refining initial programme theories (IPTs), we will generate a pragmatic evidence base explaining how contextual factors trigger mechanisms that lead to intended and unintended outcomes and why implementation varies across the different settings. Methods and analysis We conceptualise the implementation of CPGs for PE prevention and management as complex social interventions operating within complex adaptive systems. The realist synthesis method will be employed to systematically review the literature for evidence synthesis. The review process will be conducted in five phases, each iteratively building on the previous phase to uncover generative causation and refine the IPTs. We will identify articles through iterative purposive searching in six electronic databases and search engines (Google Scholar, PubMed, Cochrane, MEDLINE, EMBASE Global Health) and through screening WHO sources. Advisory group consultations will be held to formulate, prioritise and refine IPTs. To conceptualise our realist theories through generative causation, we will analyse the data using a retroductive approach, an integration of inductive, deductive and abductive reasoning. We will inductively examine theoretical insights related to five established care moments and explore how CPGs operate during these moments, including where and how they fail to work as intended. The five care moments are: (1) Risk assessment/prevention, (2) Diagnosing disease, (3) Management of PE without severe features, (4) With severe features and (5) Decision making around birth. Deductive reasoning will support sense-making of evidence-based theories through the lens of theories that have been used to explain the adoption of guidelines in healthcare settings. Lastly, abductive reasoning, centring researcher hunches, will help to unearth mechanisms that have been insufficiently detailed in the literature. The intervention-context-actor-mechanism-outcome heuristic will be used to configure programme theories and articulate the theories using the if-then statements. Ethics and dissemination This project is part of the larger PREvention of Severe Hypertensive Adverse events (PRESHA) project, which aims to improve the detection, prevention and management of PE in Tanzania. PRESHA has ethical clearance from the Regional Ethics Board in Norway and the National Health Research Ethics Committee in Tanzania. Findings of the review will support the contextual development of CPGs for the prevention and management of PE, which will be implemented within the context of the PRESHA trial.

This chapter focuses on maternal health in the context of vulnerable populations and international development, drawing from the experience of the Mozambique–Canada Maternal Health Project. The Project focuses on improving maternal and reproductive health and rights in rural Mozambique. Within the larger project, three research projects are highlighted, as each project utilizes different methods. The maternal experience study is a longitudinal qualitative critical interpretive study that explores diverse maternal experiences with participants using storytelling. The maternal near-miss study focuses on women who survive death from life-threatening obstetrical or other complications related to pregnancy and childbirth. This mixed-methods study uses hospital-based data as well as qualitative interviews with women who have had a near-miss experience. Using realist methods, the maternal waiting home study examines how and why the maternal waiting homes built by the Project and its context would lead to behavioral outcomes, and for whom. The chapter ends with key lessons learned, drawing from benefits and challenges encountered in implementing these projects.
