Effectiveness of Health Education in Community-based Malaria Prevention and Control Interventions in sub-Saharan Africa: A Systematic Review

Objective: This review assessed the effectiveness of health education in community-based malaria prevention and control interventions in sub-Saharan Africa (SSA). Methods: We systematically reviewed published and unpublished literature, searching 7 databases and 3 websites namely Malaria Journal, World Health Organization and Centre for Disease Control and Prevention to find relevant studies. Study designs included were randomized controlled trials, non-randomized trials, quasi experiments, before and after studies, and surveys. A narrative synthesis was performed on the extracted data. Results: Seventeen studies were included in the review. Nine studies covered health education interventions on Insecticide Treated bet Nets (ITNs), three utilised health education to promote Intermittent Presumptive Treatment in pregnancy (IPTp), four reported on the effect of health education in home-based management of malaria whilst one study focused on environmental management in malaria control. Factors found to affect health education in malaria control and prevention interventions included educational level of participants, the nature of health messages and the level of community involvement. Conclusion: The results of the review suggest that health education interventions are effective and remain a valuable tool in community-based malaria prevention and control interventions in SSA. This review found moderate evidence that health education interventions influence the uptake of community-based malaria prevention and control interventions, enhance knowledge about malaria and generally improve malaria prevalence and mortality in children under five and pregnant women.   Key words Malaria, systematic review, health education, sub-Saharan Africa

Exploring community perspectives on national health insurance policy in Ghana

Even though a number of studies have examined the implementation of National Health Insurance Scheme (NHIS) in Ghana, its equity and access significance in relation to community perspective has not been assessed nationally. We looked at the NHIS from the perspective of local communities in focus groups discussions (FGDs) and key informant interviews. Qualitative data from nine key informant interviews and seventy-two community respondents in nine focus group discussions were collected. The focus groups took place in seven different communities purposely selected. The data were analysed using thematic network approach. The key informants and focus groups were analysed together. The findings noted a disconnection between NHIS policy and community life. More so, the findings showed an explicit link between equity and access with its impacts on health outcomes. The qualitative results noted lack of voice and understanding as features limiting people from accessing the NHIS facilities. Understanding of equity as a key theme revealed: first, lack of stakeholder engagement and consultation or participation in the NHIS decision making process. Second, the NHIS displayed an overreliance on healthcare and an emphasis on a biomedical approach. Finally, despite being a pro- poor intervention by name, practical management of the NHIS is transmitted down vertical silos from the national level, with the lack of joined-up government at the centre undermining local partnerships. Thus, not only are national expectations being dashed locally, local expectations are dashed nationally. We proposed that community viewpoints should be given higher priority given that NHIS has since its inception been associated with medical treatments and biomedical paradigm. Promoting community participation, understanding and voices should be recognised to shape the future NHIS policy and practice

Cash transfers and the social determinants of health : a conceptual framework

Cash transfers (CTs) can play a significant role in tackling the social determinants of health (SDoH), but to date there is a lack of conceptual framework for understanding CTs linkages to the SDoH. This article proposes a framework that identifies the linkages between CTs and SDoH, discusses its implications, and argues for active involvement of health promoters in CT design, implementation and evaluation. The development of the framework followed two stages: evidence review and stakeholder involvement. The evidence review entailed a systematic literature search to identify published and unpublished impact evaluation studies of CTs in sub-Saharan Africa. Critical reflection on the evidence synthesized from the literature formed the basis for the development of the framework. Interviews with CT policy makers, managers and development partners were also carried out to help refine the framework. Interviews were audio-recorded and transcripts were analysed using thematic framework analysis. The study finds that there is limited recognition of SDoH in CT policy making and implementation. The evidence reviewed, however, points to strong impacts of CTs on SDoH. The framework thus conceptualizes how CTs work to influence a broad range of SDoH and health inequities. It also highlights how CT architecture and contexts may influence program impacts. The proposed framework can be used by policy makers to guide CT design, adaptation and operations, and by program managers and researchers to inform CTs’ evaluations, respectively. The framework suggests that to optimize CT impact on SDoH and reduce health inequities, health promoters should be actively engaged in terms of the programs design, implementation and evaluation

Examining the Effects of Microfinance Services on Incomes and Business Capital in Ghana: The Case of Sinapi Aba Trust Beneficiaries

Microfinance institutions operate with the underlying philosophy that providing easier access to financial services for low income earners can result in increased incomes and business capital of beneficiaries to assist in reducing income inequality. This paper sets out to examine financial intermediation theory, through microfinance services, to expound its effects on incomes of beneficiaries of Sinapi Aba Trust (SAT) microfinance institution and provides empirical evidence on how microfinance services affect the incomes and business capital of beneficiaries in Ghana. The cross sectional approach was used to collect data from 361 beneficiaries. Both quantitative and qualitative tools were used, and the findings indicate that SAT services led to improvements in beneficiaries incomes. Even though most of the SAT beneficiaries were classified under the lower middle income group, they were earning incomes higher than the national average for the lower middle income group. Beneficiaries in the manufacturing sector earned higher incomes while those from the agricultural, and food sub-sector earned the lowest. Individual loan beneficiaries had the highest incomes compared to those who obtained group loans. It was further identified that larger loan sizes led to increased incomes. The conclusion, for practitioners, is that microfinance has the potential of increasing the incomes of beneficiaries.

Lifestyle interventions for type 2 diabetes management among migrants and ethnic minorities living in industrialized countries : a systematic review and meta-analyses

The objective of this systematic review was to determine the effectiveness of lifestyle interventions to improve the management of type 2 diabetes mellitus (T2DM) among migrants and ethnic minorities. Major searched databases included MEDLINE (via PubMed), EMBASE (via Ovid) and CINAHL. The selection of studies and data extraction followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. In the meta-analysis, significant heterogeneity was detected among the studies (I 2 >50%), and hence a random effects model was used. Subgroup analyses were performed to compare the effect of lifestyle interventions according to intervention approaches (peer-led vs community health workers (CHWs)-led). A total of 17 studies were included in this review which used interventions delivered by CHWs or peer supporters or combination of both. The majority of the studies assessed effectiveness of key primary (hemoglobin (HbA1c), lipids, fasting plasma glucose) and secondary outcomes (weight, body mass index, blood pressure, physical activity, alcohol consumption, tobacco smoking, food habits and healthcare utilization). Meta-analyses showed lifestyle interventions were associated with a small but statistically significant reduction in HbA1c level (-0.18%; 95% CI-0.32% to-0.04%, p=0.031). In subgroup analyses, the peer-led interventions showed relatively better HbA1c improvement than CHW-led interventions, but the difference was not statistically significant (p=0.379). Seven studies presented intervention costs, which ranged from US$131 to US$461 per participant per year. We conclude that lifestyle interventions using either CHWs or peer supporters or a combination of both have shown modest effectiveness for T2DM management among migrants of different background and origin and ethnic minorities. The evidence base is promising in terms of developing culturally appropriate, clinically sound and cost-effective intervention approaches to respond to the growing and diverse migrants and ethnic minorities affected by diabetes worldwide

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

Ghanaian media coverage of violence against women and girls: implications for health promotion

Abstract Background Violence against women and girls (VAWG) is an important public health issue. Framing studies indicate that how the news media cover public health issues is critical for designing effective health promotion interventions. Notwithstanding this, there is little research particularly in low-and middle-income country context examining how the news media frame VAWG. This paper examines news coverage of VAWG in Ghana, and the implications of this for health promotion. Methods This study used frame analysis as the methodological framework in examining how VAWG in Ghana is represented by the media. Qualitative content analysis approach to frame analysis was performed on 48 news articles which constituted the unit of analysis. Results The findings indicate that media framing of VAWG was episodic in nature as the acts of violence perpetrated against women and girls were presented as individual cases without reference to the wider social contexts within which they occurred. Similarly, victim blaming language was largely used in the news articles. In framing VAWG as an individual incident and women as helpless victims, the media fail to shape society’s perception of VAWG as a social and public health issue. Conclusions For the media in Ghana to contribute to the prevention of VAWG, there is the need for news coverage to focus on social construction of the issue, and also raise awareness about support services available to victims

Physical activity participation and the risk of chronic diseases among South Asian adults: protocol for a systematic review and meta-analysis

Abstract Background Chronic diseases contribute to about half of the adult disease burden in the South Asian region. Meanwhile, physical activity levels are declining despite the global evidence of its role in the prevention of chronic diseases. While there are a plethora of systematic reviews on the effects of physical activity on chronic diseases, there has not yet been a synthesis of the evidence concerning the nature of this relationship among people living in South Asian countries incorporating multiple chronic diseases and a focus on physical activity domains. The aim of this protocol is to describe the rationale and methods for a systematic review of published research to identify the association between physical activity and selected chronic diseases and their markers and analysis of the strength of association with a focus on physical activity domains among South Asian adults 40 years and older. Methods Nine electronic databases including Medline, PsycINFO, Embase, CENTRAL, CINAHL Plus, AgeLine, SPORTDiscus, Scopus and Web of Science will be systematically searched for papers reporting the association between physical activity and selected chronic diseases (type 2 diabetes mellitus, breast cancer, colorectal cancer, coronary heart disease, stroke, vascular diseases and musculoskeletal diseases (osteoarthritis, osteoporosis, back and neck pain)) and their markers using predefined search terms. Searches will be limited to peer-reviewed, English language papers with a quantitative design. In addition, a manual search of references of relevant systematic reviews as well as citations and references of eligible studies will also be carried out. The methodological appraisal will be performed using the National Institutes of Health quality assessment checklist for observational studies and the Effective Public Health Practice Project quality assessment tool for intervention studies. The overall quality of evidence for the study outcomes across the study designs will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. The review results will be presented in the form of narrative synthesis, and a random effects meta-analysis is planned depending on the nature of included studies and available data. Discussion This review will summarise the strength of the association between physical activity and selected chronic diseases and their markers among South Asian adults 40 years or older. The findings will provide an evidence base to guide public health policy and interventions in the South Asian region and to inform future research to address the rising burden of chronic diseases.

Factors affecting health sector involvement in public policies addressing the social determinants of health : a critical realist case study of cash transfers in Ghana

In spite of the consistent evidence of cash transfers’ (CTs) impact on the social determinants of health (SDoH) in low-and middle-income countries, and their potential for achieving health sector objectives, there is a growing concern that the health sector has not been actively involved in these programs. This study used a critical realist approach to examine the factors affecting health sector involvement in CTs in Ghana. In-depth semi-structured interviews were conducted with 20 health promoters comprising national policymakers, District Directors of Health Service, Regional/District Health Promotion Managers and health promotion academics between October 2017 and February 2018. Interviews were audio-recorded and transcripts were analysed using thematic framework analysis. In addition, policy documents concerning the Ghana CT program were reviewed. All the participants were aware of the CT program, but had limited or no involvement in it to date. The findings indicate that CTs’ cross-cutting goals and health sector mandates and responsibilities constitute the key structures and powers with the potential to trigger a more substantive involvement of the health sector in the program. Factors found to shape health sector involvement in CTs included CT policymakers’ understanding of the SDoH, national health sector leadership, evidence linking CTs to SDoH, intersectoral collaboration and politicisation of CTs. As CTs continue to adapt and expand across low-and middle-income countries, the findings from this study can help the health sector to take a more substantive role in the programs to optimise their impacts on the SDoH and health inequities

The impact of cash transfers on social determinants of health and health inequalities in sub-Saharan Africa : a systematic review

Cash transfers (CTs) are now high on the agenda of most governments in low- and middle-income countries. Within the field of health promotion, CTs constitute a healthy public policy initiative as they have the potential to address the social determinants of health (SDoH) and health inequalities. A systematic review was conducted to synthesise the evidence on CTs' impacts on SDoH and health inequalities in sub-Saharan Africa, and to identify the barriers and facilitators of effective CTs. Twenty-one electronic databases and the websites of 14 key organizations were searched in addition to grey literature and hand searching of selected journals for quantitative and qualitative studies on CTs' impacts on SDoH and health outcomes. Out of 182 full texts screened for eligibility, 79 reports that reported findings from 53 studies were included in the final review. The studies were undertaken within 24 CTs comprising 11 unconditional CTs (UCTs), 8 conditional CTs (CCTs) and 5 combined UCTs and CCTs. The review found that CTs can be effective in tackling structural determinants of health such as financial poverty, education, household resilience, child labour, social capital and social cohesion, civic participation, and birth registration. The review further found that CTs modify intermediate determinants such as nutrition, dietary diversity, child deprivation, sexual risk behaviours, teen pregnancy and early marriage. In conjunction with their influence on SDoH, there is moderate evidence from the review that CTs impact on health and quality of life outcomes. The review also found many factors relating to intervention design features, macro-economic stability, household dynamics and community acceptance of programs that could influence the effectiveness of CTs. The external validity of the review findings is strong as the findings are largely consistent with those from Latin America. The findings thus provide useful insights to policy makers and managers and can be used to optimise CTs to reduce health inequalities
