Process evaluation of a parent-child communication intervention for adolescent sexual and reproductive health in Uganda.

BACKGROUND: Previous initiatives concerning adolescent sexual and reproductive health (SRH) education in Low-or-Middle Income Countries (LMICs) have been limited by cultural norms and misinformation perpetuated within families. Responding to the paucity of research on the implementation of SRH interventions in LMICs and limited knowledge regarding their mechanisms, this study undertakes a process evaluation of a parent-focused intervention to promote parent-adolescent communication about SRH in Uganda. METHODS: This paper explores the implementation, contextual factors and mechanisms of impact of the intervention, using the Medical Research Council (MRC) guidelines for process evaluations. Implementation was evaluated through indicators of dose, fidelity and adaptations, acceptability and feasibility. The contextual factors and mechanisms of impact were evaluated to refine the intervention's causal assumptions. Data was collected during April - October 2021 in South-Western Uganda using a mixed-methods approach, including document analysis, intervention observations, interviews, focus group discussions and most significant change stories. RESULTS: The acceptability of the intervention was related to its community engagement, the strong rapport with delivery agents, and individual characteristics of participants. Five contextual factors influencing implementation were highlighted; (i) cultural norms, (ii) perceptions about youth SRH, (iii) poverty, (iv) Covid-19 pandemic, and (v) prior research projects in the community. When considering the intervention's mechanisms of impact, four causal pathways were identified; (i) Awareness of SRH needs helped parents overcome stigma, (ii) Parenting skills training improved SRH communication, (iii) Group learning stimulated shared parenting, and (iv) Group learning improved co-parenting. CONCLUSION: The paper presented three key learnings and corresponding recommendations for future research. Firstly, implementation success was credited to meaningful community engagement which improved acceptability and uptake. Secondly, the complex influences of contextual factors highlighted the need for contextual analysis in research studies to inform intervention design. Finally, this evaluation recognised the interplay between mechanisms of impact and suggested further research consider such combined impacts when designing intervention content.

'I accept his manhood is on life-support': A qualitative understanding of the impact of diabetes on sexual relationships among men and women living with type 2 diabetes and their partners in South Africa.

AIMS: To explore the impact of diabetes on sexual relationships among men and women living with type 2 diabetes People living with type 2 diabetes (PLWD) and their partners in Cape Town, South Africa. METHODS: As part of a larger study developing an intervention to improve type 2 diabetes mellitus (T2DM) self management, we conducted in-depth individual interviews with 10 PLWD and their partners without diabetes about experiences living with T2DM, between July 2020 and January 2021. We used inductive thematic analysis. RESULTS: Both PLWD and partners felt that their sexual relationships and desires changed post-diagnosis, in ways beyond biomedical issues. Although couples' reports on the quality of their sexual relationships were concordant, most participants had not communicated their sexual desires and concerns with each other, causing unhappiness and fears of disappointing or losing their partner. Participants felt uninformed about sexual dysfunction but had not discussed this with their healthcare provider, leading to increased anxiety. CONCLUSION: PLWD and their partners need more informational support to increase their understanding of diabetes-associated sexual dysfunction and to decrease fears and anxiety. Strengthening communication within couples on sexual issues may empower them to find solutions to problems experienced. This may improve couples' relationships and quality of life, and indirectly result in better self management of T2DM.

The role of community health workers in primary healthcare in the WHO-EU region: a scoping review.

BACKGROUND: Existing evidence on the role of community health workers (CHWs) in primary healthcare originates primarily from the United States, Canada and Australia, and from low- and middle-income countries. Little is known about the role of CHWs in primary healthcare in European countries. This scoping review aimed to contribute to filling this gap by providing an overview of literature reporting on the involvement of CHWs in primary healthcare in WHO-EU countries since 2001 with a focus on the role, training, recruitment and remuneration. METHODS: This systematic scoping review followed the guidelines of the Preferred Reporting Items for Systematic reviews and Meta-Analyses, extension for Scoping Reviews. All published peer-reviewed literature indexed in PubMed, Web of Science, and Embase databases from Jan 2001 to Feb 2023 were reviewed for inclusion. Included studies were screened on title, abstract and full text according to predetermined eligibility criteria. Studies were included if they were conducted in the WHO-EU region and provided information regarding the role, training, recruitment or remuneration of CHWs. RESULTS: Forty studies were included in this review, originating from eight countries. The involvement of CHWs in the WHO-EU regions was usually project-based, except in the United Kingdom. A substantial amount of literature with variability in the terminology used to describe CHWs, the areas of involvement, recruitment, training, and remuneration strategies was found. The included studies reported a trend towards recruitment from within the communities with some form of training and payment of CHWs. A salient finding was the social embeddedness of CHWs in the communities they served. Their roles can be classified into one or a combination of the following: educational; navigational and supportive. CONCLUSION: Future research projects involving CHWs should detail their involvement and elaborate on CHWs' role, training and recruitment procedures. In addition, further research on CHW programmes in the WHO-EU region is necessary to prepare for their integration into the broader national health systems.

Developing, implementing, and monitoring tailored strategies for integrated knowledge translation in five sub-Saharan African countries.

BACKGROUND: Integrated knowledge translation (IKT) through strategic, continuous engagement with decision-makers represents an approach to bridge research, policy and practice. The Collaboration for Evidence-based Healthcare and Public Health in Africa (CEBHA +), comprising research institutions in Ethiopia, Malawi, Rwanda, South Africa, Uganda and Germany, developed and implemented tailored IKT strategies as part of its multifaceted research on prevention and care of non-communicable diseases and road traffic injuries. The objective of this article is to describe the CEBHA + IKT approach and report on the development, implementation and monitoring of site-specific IKT strategies. METHODS: We draw on findings derived from the mixed method IKT evaluation (conducted in 2020-2021), and undertook document analyses and a reflective survey among IKT implementers. Quantitative data were analysed descriptively and qualitative data were analysed using content analysis. The authors used the TIDieR checklist to report results in a structured manner. RESULTS: Preliminary IKT evaluation data (33 interviews with researchers and stakeholders from policy and practice, and 31 survey responses), 49 documents, and eight responses to the reflective survey informed this article. In each of the five African CEBHA + countries, a site-specific IKT strategy guided IKT implementation, tailored to the respective national context, engagement aims, research tasks, and individuals involved. IKT implementers undertook a variety of IKT activities at varying levels of engagement that targeted a broad range of decision-makers and other stakeholders, particularly during project planning, data interpretation, and output dissemination. Throughout the project, the IKT teams continued to tailor IKT strategies informally and modified the IKT approach by responding to ad hoc engagements and involving non-governmental organisations, universities, and communities. Challenges to using systematic, formalised IKT strategies arose in particular with respect to the demand on time and resources, leading to the modification of monitoring processes. CONCLUSION: Tailoring of the CEBHA + IKT approach led to the inclusion of some atypical IKT partners and to greater responsiveness to unexpected opportunities for decision-maker engagement. Benefits of using systematic IKT strategies included clarity on engagement aims, balancing of existing and new strategic partnerships, and an enhanced understanding of research context, including site-specific structures for evidence-informed decision-making.

Perceived cardiovascular disease risk and tailored communication strategies among rural and urban community dwellers in Rwanda: a qualitative study.

BACKGROUND: In Rwanda, cardiovascular diseases (CVDs) are the third leading cause of death, and hence constitute an important public health issue. Worldwide, most CVDs are due to lifestyle and preventable risk factors. Prevention interventions are based on risk factors for CVD risk, yet the outcome of such interventions might be limited by the lack of awareness or misconception of CVD risk. This study aimed to explore how rural and urban population groups in Rwanda perceive CVD risk and tailor communication strategies for estimated total cardiovascular risk. METHODS: An exploratory qualitative study design was applied using focus group discussions to collect data from rural and urban community dwellers. In total, 65 community members took part in this study. Thematic analysis with Atlas ti 7.5.18 was used and the main findings for each theme were reported as a narrative summary. RESULTS: Participants thought that CVD risk is due to either financial stress, psychosocial stress, substance abuse, noise pollution, unhealthy diets, diabetes or overworking. Participants did not understand CVD risk presented in a quantitative format, but preferred qualitative formats or colours to represent low, moderate and high CVD risk through in-person communication. Participants preferred to be screened for CVD risk by community health workers using mobile health technology. CONCLUSION: Rural and urban community members in Rwanda are aware of what could potentially put them at CVD risk in their respective local communities. Community health workers are preferred by local communities for CVD risk screening. Quantitative formats to present the total CVD risk appear inappropriate to the Rwandan population and qualitative formats are therefore advisable. Thus, operational research on the use of qualitative formats to communicate CVD risk is recommended to improve decision-making on CVD risk communication in the context of Rwanda.

Motivational determinants of physical activity in disadvantaged populations with (pre)diabetes: a cross-cultural comparison.

BACKGROUND: Understanding motivational determinants of physical activity (PA) is essential to guide the implementation of PA at individual and population level. Knowledge about the cross-cultural generalizability of these determinants is lacking and they have mostly been studied as separate factors. This study compares a motivational process model across samples from diverse populations with, or at risk of diabetes. METHODS: Measurement invariance of barrier identified regulation, barrier self-efficacy and social support was assessed in a rural Ugandan sample (n = 712) and disadvantaged samples with high proportions of immigrants in urban South Africa (n = 566) and Sweden (n = 147). These motivational determinants were then compared through multigroup structural equation modeling. RESULTS: The studied motivational constructs showed scalar invariance. Latent mean levels of perceived social support and barrier self-efficacy were lower in South Africa and Sweden. Structural models (for different PA outcomes) were not consistent across settings except for the association between perceived social support and identified regulation. Identified regulation was only associated with vigorous PA in Uganda and with moderate PA in South Africa. The association between social support and PA outcomes ranged from weak to not significant and the association between self-efficacy and PA was not significant. Self-reported PA was highest in Uganda and lowest in Sweden. Self-reported vigorous PA was significantly related to lower hemoglobin A1c levels, while moderate PA was not. CONCLUSIONS: Findings suggest that: 1) it is feasible to compare a motivational process model across diverse settings; 2) there is lower perceived social support and self-efficacy in the urban, migrant samples; 3) identified regulation is a more promising determinant of PA than self-efficacy or social support in these populations; 4) associations between motivational determinants and PA depend on the perceived type and/or intensity of PA; 5) perceived relatedness functions as a basic psychological need across diverse settings; and 6) people's perception of the PA they perform depends on their perceived level of intensity of PA which would have major implications for health promotion.

Explaining the impact of mHealth on maternal and child health care in low- and middle-income countries: a realist synthesis.

BACKGROUND: Despite the growing global application of mobile health (mHealth) technology in maternal and child health, contextual factors, and mechanisms by which interventional outcomes are generated, have not been subjected to a systematic examination. In this study, we sought to uncover context, mechanisms, and outcome elements of various mHealth interventions based on implementation and evaluation studies to formulate theories or models explicating how mHealth interventions work (or not) both for health care providers and for pregnant women and mothers. METHOD: We undertook a realist synthesis. An electronic search of five online databases (PubMed/Medline, Google Scholar, Scopus, Academic Search Premier and Health Systems Evidence) was performed. Using appropriate Boolean phrases terms and selection procedures, 32 articles were identified. A theory-driven approach, narrative synthesis, was applied to synthesize the data. Thematic content analysis was used to delineate elements of the intervention, including its context, actors, mechanisms, and outcomes. Abduction and retroduction were applied using a realist evaluation heuristic tool to formulate generative theories. RESULTS: We formulated two configurational models illustrating how and why mHealth impacts implementation and uptake of maternal and child health care. Implementation-related mechanisms include buy-in from health care providers, perceived support of health care providers' motivation and perceived ease of use and usefulness. These mechanisms are influenced by adaptive health system conditions including organization, resource availability, policy implementation dynamics, experience with technology, network infrastructure and connectivity. For pregnant women and mothers, mechanisms that trigger mHealth use and consequently uptake of maternal and child health care include perceived satisfaction, motivation and positive psychological support. Information overload was identified as a potential negative mechanism impacting the uptake of maternal and child health care. These mechanisms are influenced by health system conditions, socio-cultural characteristics, socio-economic and demographics characteristics, network infrastructure and connectivity and awareness. CONCLUSION: Models developed in this study provide a detailed understanding of implementation and uptake of mHealth interventions and how and why they impact maternal and child health care in low- and middle-income countries. These models provide a foundation for the 'white box' of theory-driven evaluation of mHealth interventions and can improve rollout and implementation where required.

Integrated knowledge translation to advance noncommunicable disease policy and practice in South Africa: application of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework.

BACKGROUND: In response to the "know-do" gap, several initiatives have been implemented to enhance evidence-informed decision-making (EIDM). These include individual training, organizational culture change management, and legislative changes. The importance of relationships and stakeholder engagement in EIDM has led to an evolution of models and approaches including integrated knowledge translation (IKT). IKT has emerged as a key strategy for ensuring that engagement is equitable, demand-driven, and responsive. As a result, the African-German Collaboration for Evidence-Based Healthcare and Public Health in Africa (CEBHA+) incorporated an IKT approach to influence noncommunicable diseases (NCD) policy and practice. We documented the phased process of developing, implementing, and monitoring the IKT approach in South Africa; and explored the appropriateness of using the exploration, preparation, implementation, and sustainment (EPIS) framework for this purpose. METHODS: We mapped the South Africa IKT approach onto the EPIS framework using a framework analysis approach. Notes of team meetings, stakeholder matrices, and engagement strategies were analysed and purposefully plotted against the four phases of the framework in order to populate the different constructs. We discussed and finalized the analysis in a series of online iterations until consensus was reached. RESULTS: The mapping exercise revealed an IKT approach that was much more iterative, dynamic, and engaging than initially thought. Several constructs (phase-agnostic) remained important and stable across EPIS phases: stable and supportive funding; committed and competent leadership; skilled and dedicated IKT champions; diverse and established personal networks; a conducive and enabling policy environment; and boundary-spanning intermediaries. Constructs such as "innovations" constantly evolved and adapted to the changing inner and outer contexts (phase-specific). CONCLUSIONS: Using the EPIS framework to interrogate, reflect on, and document our IKT experiences proved extremely relevant and useful. Phase-agnostic constructs proved critical to ensure resilience and agility of NCD deliberations and policies in the face of highly dynamic and changing local contexts, particularly in view of the current coronavirus disease 2019 (COVID-19) pandemic. Bridging IKT with a framework from implementation science helps to reflect on this process and can guide the development and planning of similar interventions and strategies.

Mixed method evaluation of the CEBHA+ integrated knowledge translation approach: a protocol.

BACKGROUND: The Collaboration for Evidence-based Healthcare and Public Health in Africa (CEBHA+) is a research consortium concerned with the prevention, diagnosis and treatment of non-communicable diseases. CEBHA+ seeks to engage policymakers and practitioners throughout the research process in order to build lasting relationships, enhance evidence uptake, and create long-term capacity among partner institutions in Ethiopia, Malawi, Rwanda, South Africa and Uganda in collaboration with two German universities. This integrated knowledge translation (IKT) approach includes the formal development, implementation and evaluation of country specific IKT strategies. METHODS: We have conceptualised the CEBHA+ IKT approach as a complex intervention in a complex system. We will employ a comparative case study (CCS) design and mixed methods to facilitate an in-depth evaluation. We will use quantitative surveys, qualitative interviews, quarterly updates, and a policy document analysis to capture the process and outcomes of IKT across the African CEBHA+ partner sites. We will conduct an early stage (early 2020) and a late-stage evaluation (early 2022), triangulate the data collected with various methods at each site and subsequently compare our findings across the five sites. DISCUSSION: Evaluating a complex intervention such as the CEBHA+ IKT approach is complicated, even more so when undertaken across five diverse countries. Despite conceptual, methodological and practical challenges, our comparative case study addresses important evidence gaps: While involving decision-makers in the research process is gaining traction worldwide, we still know very little regarding (i) whether this approach really makes a difference to evidence uptake, (ii) the mechanisms that make IKT successful, and (iii) relevant differences across socio-cultural contexts. The evaluation described here is intended to provide relevant insights on all of these aspects, notably in countries in Sub-Saharan Africa, and is expected to contribute to the science of IKT overall.

Using photography to explore people with diabetes' perspectives on food environments in urban and rural South Africa.

Diabetes, a serious disease resulting in significant morbidity and early mortality, is currently on the rise globally. A major contributor to this observed increase in low- and middle-income countries, such as South Africa, has been the observed change in diet at the population level-a shift from a traditional diet, to one consisting of more energy-dense, processed foods, with more added sugar, salt and fat. Implicated in this degradation of diet are changing local food environments. Participant-generated digital photographs and facilitated focus group discussion-style workshops were utilized to better understand diabetic community members' perspectives on their food environments in both an urban and rural setting in South Africa, and what (and how) aspects of these physical environments influence their food acquisition behaviours and diet. Qualitative data were analysed using a deductive thematic analysis approach. The resulting predominant themes of accessibility, availability and affordability are outlined and discussed. Findings from this study have implications beyond the self-management of diabetes and extend to the self-management and reduction of all diet-related non-communicable diseases.

Black Lives Matter in health promotion: moving from unspoken to outspoken.

Racism is a public health crisis. Black communities (including Africans, the African diaspora and people of African descent) experience worse health outcomes as demonstrated by almost any measure of health and wellbeing-e.g. life expectancy; disease prevalence; maternal mortality rates. While health promotion has its foundation in promoting equity and social justice, it is clear that however well-intended, we are not affecting meaningful change for Black communities quickly enough. Through this article, we outline the intersection of social determinants of health and anti-Black racism. We describe how in the first 8 months of 2020 Black communities around the globe have been disproportionately affected by COVID-19, while also having to respond to new instances of police brutality. We assert that the time has come for health promotion to stop neutralizing the specific needs of Black communities into unspoken 'good intentions'. Instead, we offer some concrete ways for the field to become outspoken, intentional and honest in acknowledging what it will take to radically shift how we promote health and wellbeing for Black people.

Combining the theory of change and realist evaluation approaches to elicit an initial program theory of the MomConnect program in South Africa.

BACKGROUND: One of the Sustainable Development Goals is to reduce the global maternal mortality ratio to less than 70 per 100,000 live births by 2030. In South Africa, the flagship National Department of Health MomConnect program was launched in 2014 to strengthen the quality of maternal and child health (MCH) services and improve mortality outcomes. MomConnect was rapidly rolled out with a limited understanding of how and why the program was expected to work even though studies had shown the effectiveness of the MomConnect program in improving the uptake of MCH services. This study aimed to unearth the initial program theory of the MomConnect program based on explicit and implicit assumptions of how the program was organized and expected to work. METHODS: We conducted a document analysis using design- and implementation-related documents of the MomConnect program guided by the principles of Theory of Change (ToC) and Realist Evaluation (RE). Content and thematic analysis approaches were deductively applied to analyze the documents toward constructing ToC and RE-informed models. Abductive thinking and retroduction were further applied to the realist-informed approach to link program context, mechanisms, and outcomes to construct the initial program theory. RESULTS: ToC and RE-informed models illustrated how the MomConnect program was organized and expected to work. The process of constructing the ToC provided the platform for the development of the initial program theory, which identified three critical elements: (1) the central modalities of the MomConnect program; (2) the intended outcomes; and (3) the tentative causal links indicating, in a stepwise manner of, how the outcomes were intended to be achieved. The RE approach 'enhanced' the causal links by identifying relevant programmatic contexts and linking the postulated mechanisms of action (empowerment, encouragement, motivation, and knowledge acquisition) to program outcomes. CONCLUSION: The application of ToC and RE provided an explicitly cumulative approach to knowledge generation in unveiling the initial program theory of MomConnect rather than delivering answers to questions of program effectiveness.

Understanding key drivers of performance in the provision of maternal health services in eastern cape, South Africa: a systems analysis using group model building.

BACKGROUND: The Eastern Cape Province reports among the poorest health service indicators in South Africa with some of its districts standing out as worst performing as regards maternal health indicators. To understand key drivers and outcomes of this underperformance and to explore whether a participatory analysis could deepen action-oriented understanding among stakeholders, a study was conducted in one of the chronically poorly performing districts. METHODS: The study used a systems analysis approach to understand the drivers and outcomes affecting maternal health in the district in order to identify key leverage points for addressing the situation. The approach included semi-structured interviews with a total of 24 individuals consisting health system managers at various levels, health facility staff and patients. This was followed by a participatory group model building exercise with 23 key stakeholders to analyze system factors and their interrelationships affecting maternal health in the district using rich pictures and interrelationship diagraphs (IRDs) and finally the development of causal loop diagrams (CLDs). RESULTS: The stakeholders were able to unpack the complex ways in which factors were interrelated in contributing to poor maternal health performance and identified the feedback loops which resulted in the situation being intractable, suggesting strategies for sustainable improvement. Quality of leadership was shown to have a pervasive influence on overall system performance by linking to numerous factors and feedback loops, including staff motivation and capacity building. Staff motivation was linked to quality of care in turn influencing patient attendance and feeding back into staff motivation through its impact on workload. Without attention to workload, patient waiting times and satisfaction, the impact of improved leadership and staff support on staff competence and attitudes would be diminished. CONCLUSION: Understanding the complex interrelationships of factors in the health system is key to identifying workable solutions especially in the context of chronic health systems challenges. Systems modelling using group model building methods can be an efficient means of supporting stakeholders to recognize valuable resources within the context of a dysfunctional system to strengthen systems performance.

Reducing the overall HIV-burden in South Africa: is 'reviving ABC' an appropriate fit for a complex, adaptive epidemiological HIV landscape?

This article questions the recommendations to 'revive ABC (abstain, be faithful, condomise)' as a mechanism to 'educate' people in South Africa about HIV prevention as the South African National HIV Prevalence, Incidence and Behaviour Survey, 2012, suggests. We argue that ABC was designed as a response to a particular context which has now radically changed. In South Africa the contemporary context reflects the mass roll-out of antiretroviral treatment; significant bio-medical knowledge gains; a generalised population affected by HIV that has made sense of and embodied those diverse experiences; and a government committed to confronting the epidemic. We suggest that the situation can now be plausibly conceptualised as a complex, adaptive epidemiological landscape that could benefit from an expansion of the existing, 'descriptive' prevention paradigm towards strategies that focus on the dynamics of transmission. We argue for this shift by proposing a theoretical framework based on complexity theory and pattern management. We interrogate one educational prevention heuristic that emphasises the importance of risk-reduction through the lens of transmission, called A-3B-4C-T. We argue that this type of approach provides expansive opportunities for people to engage with the epidemic in contextualised, innovative ways that supersede the opportunities afforded by ABC. We then suggest that framing the prevention imperative through the lens of 'dynamic prevention' at scale opens more immediate opportunities, as well as developing a future-oriented mind-set, than the 'descriptive prevention' parameters can facilitate. The parameters of the 'descriptive prevention' paradigm, that maintain - and partially reinforce - the presence of ABC, do not have the flexibility required to develop the armamentarium of tools required to contribute to the management of a complex epidemiological landscape. Uncritically adhering to both the 'descriptive paradigm', and ABC, represents an historically dislocated form of prevention - with restrictive options for reducing the overall burden of HIV-related challenges in South Africa.

Re-imagining decision making: addressing a discrete social driver of HIV/AIDS through the lens of complexity science.

This article argues that decision making is a discrete social driver that can be associated with the HIV/AIDS epidemic in the Limpopo province in South Africa. The authors argue that complexity science can inform future research and interventions by presenting two decision making frameworks arising out of complexity science that have the potential to enable young people to better negotiate decision-making contexts whilst simultaneously opening spaces of dialogue that can mitigate the impact of HIV-risk in specific, punctuated contexts. The methodological design was prompted by findings from youth-oriented community engagement projects that include Communication Conversations and Sex & Relationships Education. The proposed methods have the potential to exploit the phenomenon of leadership emergence as a product of decision making at critical moments. This has the potential to promote the growth of home-grown leadership skill sets that make sense to young people and to enable them better manage their own health, thus reducing risk and vulnerability to HIV infection and sexual violence.

The shifting roles of community health workers in the prevention and management of Noncommunicable disease during COVID-19 Pandemic: A scoping review.

Community Health Workers (CHWs) play a crucial role in the prevention and management of noncommunicable diseases (NCDs). The COVID-19 pandemic triggered the implementation of crisis-driven responses that involved shifts in the roles of CHWs in terms of delivering services for people with NCDs. Strategically aligning these shifts with health systems is crucial to improve NCD service delivery. The aim of this review was to identify and describe COVID-19-triggered shifting roles of CHWs that are promising in terms of NCD service delivery. We searched Ovid Medline, Embase, CINAHL, Web of Science, and CABI for Global Health for relevant articles published between Jan 1, 2020, and Feb 22, 2022. Studies that were conducted within a COVID-19 context and focused on the shifted roles of CHWs in NCD service delivery were included. We used PRISMA guidelines to report the findings. A total of 25 articles from 14 countries were included in this review. We identified 12 shifted roles of CHWs in NCD service delivery during COVID-19, which can be categorised in three dimensions: enhanced role of CHWs that include additional tasks such as medication delivery, extended roles such as the delivery of NCD services at household level and in remote communities; and enabled roles through the use of digital health technologies. Health and digital literacy of people with NCDs, access to internet connectivity for people with NCDs and the social and organizational context where CHWs work influenced the implementation of the shifted roles of CHWs. In conclusion, the roles of CHWs have shifted during COVID-19 pandemic to include the delivery additional NCD services at home and community levels, often supported by digital technologies. Given the importance of the shifting roles in the prevention and management of NCDs, adaptation and integration of these shifted roles into the routine activities of CHWs in the post-COVID period is recommended.

Nutrition policy reforms to address the double burden of malnutrition in Zambia: a prospective policy analysis.

The evolution of nutrition patterns in Zambia has resulted in the coexistence of undernutrition and overnutrition in the same population, the double burden of malnutrition. While Zambia has strong policies addressing undernutrition and stunting, these do not adequately address food environment drivers of the double burden of malnutrition and the adolescent age group and hence the need for nutrition policy reforms. We conducted a theory-based qualitative prospective policy analysis involving in-depth interviews with nutrition policy stakeholders and policy document review to examine the feasibility of introducing nutrition policy options that address the double burden of malnutrition among adolescents to identify barriers and facilitators to such policy reforms. Using the multiple streams theory, we categorized the barriers and facilitators to prospective policy reforms into those related to the problem, policy solutions and politics stream. The use of a life-course approach in nutrition programming could facilitate policy reforms, as adolescence is one of the critical invention points in a person's lifecycle. Another key facilitator of policy reform was the availability of institutional infrastructure that could be leveraged to deliver adolescent-focused policies. However, the lack of evidence on the burden and long-term impacts of adolescent nutrition problems, the food industry's strong influence over governments' policy agenda setting and the lack of public awareness to demand better nutrition were perceived as critical barriers to policy reforms. In addition, the use of the individual responsibility framing for nutrition problems was dominant among stakeholders. As a result, stakeholders did not perceive legislative nutrition policy options that effectively address food environment drivers of the double burden of malnutrition to be feasible for the Zambian context. Policy entrepreneurs are required to broker policy reforms that will get legislative policy options on the government's agenda as they can help raise public support and re-engineer the framing of nutrition problems and their solutions in Zambia.

Mapping of food environment policies in Zambia: a qualitative document analysis.

BACKGROUND: The food environment in which people exercise food choices significantly impacts their dietary patterns. Policies that limit the availability, affordability, and access to unhealthy food while increasing that of healthier alternatives help build healthy food environments, which are required to address the double burden of malnutrition. This study aimed to assess the availability of food environment policies in Zambia. METHOD: We applied a two-step qualitative document analysis to identify policy content relating to healthy food environments from global and Zambia-specific nutrition-related policy documents. In the first step, global policy documents were analyzed to develop a reference point for globally recommended policies for healthy food environments. In the second step, Zambia's nutrition-related policies were analyzed to identify content relating to healthy food environments. The identified policy content was then mapped against the global reference point to identify food environment policy gaps. RESULTS: Our analysis of global policy recommendations identified five broad categories of policy provisions: information and education based; regulatory and legislative tools; strategies to promote production and access to healthy food production; social protection-based strategies and guiding principles for governments relating to multisectoral collaboration and governance. Our analysis found that Zambian Government policy documents in the health, agriculture, education, and national planning and development sectors have policy provisions for healthy food environments. While these policy provisions generally covered all five reference categories, we found policy gaps in the regulatory and legislative tools category relative to global recommendations. CONCLUSION: Zambia's food environment policy landscape must include globally recommended regulatory and legislative policy measures like restricting the marketing of unhealthy foods and non-alcoholic beverages to children. Nutrition policy reforms are required to facilitate the introduction of regulatory and legislative policy measures that effectively address the double burden of malnutrition in Zambia.
