The burden of non-communicable diseases among people living with HIV in Sub-Saharan Africa: a systematic review and meta-analysis.

Background: Non-communicable diseases (NCDs) are increasing among people living with HIV (PLHIV), especially in Sub-Saharan Africa (SSA). We determined the prevalence of NCDs and NCD risk factors among PLHIV in SSA to inform health policy makers. Methods: We conducted a systematic review and meta-analysis on the prevalence of NCDs and risk factors among PLHIV in SSA. We comprehensively searched PubMed/MEDLINE, Scopus, and EBSCOhost (CINAHL) electronic databases for sources published from 2010 to July 2023. We applied the random effects meta-analysis model to pool the results using STATA. The systematic review protocol was registered on PROSPERO (registration number: CRD42021258769). Findings: We included 188 studies from 21 countries in this meta-analysis. Our findings indicate pooled prevalence estimates for hypertension (20.1% [95% CI:17.5-22.7]), depression (30.4% [25.3-35.4]), diabetes (5.4% [4.4-6.4]), cervical cancer (1.5% [0.1-2.9]), chronic respiratory diseases (7.1% [4.0-10.3]), overweight/obesity (32.2% [29.7-34.7]), hypercholesterolemia (21.3% [16.6-26.0]), metabolic syndrome (23.9% [19.5-28.7]), alcohol consumption (21.3% [17.9-24.6]), and smoking (6.4% [5.2-7.7]). Interpretation: People living with HIV have a high prevalence of NCDs and their risk factors including hypertension, depression, overweight/obesity, hypercholesterolemia, metabolic syndrome and alcohol consumption. We recommend strengthening of health systems to allow for improved integration of NCDs and HIV services in public health facilities in SSA. NCD risk factors such as obesity, hypercholesterolemia, and alcohol consumption can be addressed through health promotion campaigns. There is a need for further research on the burden of NCDs among PLHIV in most of SSA. Funding: This study did not receive any funding.

Socioeconomic Inequalities and Obesity in South Africa-A Decomposition Analysis.

BACKGROUND: Prior evidence shows that inequalities are related to overweight and obesity in South Africa. Using data from a recent national study, we examine the socioeconomic inequalities associated with obesity in South Africa and the factors associated with it. METHODS: We use quantitative data from the South African National Health and Nutrition Examination Survey (SANHANES-1) carried out in 2012. We estimate the concentration index (CI) to identify inequalities and decompose the CI to explore the determinants of these inequalities. RESULTS: We confirm the existence of pro-rich inequalities associated with obesity in South Africa. The inequalities among males are larger (CI of 0.16) than among women (CI of 0.09), though more women are obese than men. Marriage increases the risk of obesity for women and men, while smoking decreases the risk of obesity among men significantly. Higher education is associated with lower inequalities among females. CONCLUSIONS: We recommend policies to focus on promoting a healthy lifestyle, including the individual's perception of a healthy body size and image, especially among women.

Inequalities and factors associated with adherence to diabetes self-care practices amongst patients at two public hospitals in Gauteng, South Africa.

BACKGROUND: Self- management is vital to the control of diabetes. This study aims to assess the diabetes self-care behaviours of patients attending two tertiary hospitals in Gauteng, South Africa. The study also seeks to estimate the inequalities in adherence to diabetes self-care practices and associated factors. METHODS: A unique health-facilities based cross-sectional survey was conducted amongst diabetes patients in 2017. Our study sample included 396 people living with diabetes. Face-to-face interviews were conducted using a structured questionnaire. Diabetes self-management practices considered in this study are dietary diversity, medication adherence, physical activity, self-monitoring of blood-glucose, avoiding smoking and limited alcohol consumption. Concentration indices (CIs) were used to estimate inequalities in adherence to diabetes self-care practices. Multiple logistic regressions were fitted to determine factors associated with diabetes self-care practices. RESULTS: Approximately 99% of the sample did not consume alcohol or consumed alcohol moderately, 92% adhered to self-monitoring of blood-glucose, 85% did not smoke tobacco, 67% adhered to their medication, 62% had a diverse diet and 9% adhered to physical activity. Self-care practices of dietary diversity (CI = 0.1512) and exercise (CI = 0.1067) were all concentrated amongst patients with higher socio-economic status as indicated by the positive CIs, whilst not smoking (CI = - 0.0994) was concentrated amongst those of lower socio-economic status as indicated by the negative CI. Dietary diversity was associated with being female, being retired and higher wealth index. Medication adherence was found to be associated with older age groups. Physical activity was found to be associated with tertiary education, being a student and those within higher wealth index. Self-monitoring of blood glucose was associated with being married. Not smoking was associated with being female and being retired. CONCLUSION: Adherence to exercising, dietary diversity and medication was found to be sub-optimal. Dietary diversity and exercise were more prevalent among patients with higher socio-economic status. Our findings suggest that efforts to improve self- management should focus on addressing socio-economic inequalities. It is critical to develop strategies that help those within low-socio-economic groups to adopt healthier diabetes self-care practices.

A systematic review on occupational hazards, injuries and diseases among police officers worldwide: Policy implications for the South African Police Service.

BACKGROUND: Occupational hazards, injuries and diseases are a major concern among police officers, including in Sub-Saharan Africa. However, there is limited locally relevant literature for guiding policy for the South African Police Service (SAPS). The purpose of this review was to describe the occupational hazards, injuries and diseases affecting police officers worldwide, in order to benchmark policy implications for the SAPS. METHODS: We conducted a systematic review of studies using Google Scholar, PubMed and Scopus. RESULTS: A total of 36 studies were included in this review. Six revealed that police officers' exposure to accident hazards may lead to acute or chronic injuries such as sprains, fractures or even fatalities. These hazards may occur during driving, patrol or riot control. There were two studies, which confirmed physical hazards such as noise induced hearing loss (NIHL), due to exposure to high levels of noise. Three studies on chemical hazards revealed that exposure to high concentrations of carbon dioxide and general air pollution was associated with cancer, while physical exposure to other chemical substances was linked to dermatitis. Four studies on biological hazards demonstrated potential exposure to blood borne diseases from needle stick injuries (NSIs) or cuts from contaminated objects. One study on ergonomic hazards showed that musculoskeletal disorders can result from driving long distances and lifting heavy objects. There were 15 studies that indicated psychological hazards such as post-traumatic stress disorder (PTSD) as well as stress. Moreover, four studies were conducted on organizational hazards including burnout, negative workplace exposure and other factors. CONCLUSIONS: This review outlined the global impact of occupational hazards, injuries and diseases in the police force. It served as a benchmark for understanding the policy implications for South Africa, where there is paucity of studies on occupational health and safety.

Multi-Sectoral Approach to Noncommunicable Disease Prevention Policy in Sub-Saharan Africa: A Conceptual Framework for Analysis.

Conceptual frameworks for health policy analysis guide investigations into interactions between institutions, interests, and ideas to identify how to improve policy decisions and outcomes. This review assessed constructs from current frameworks and theories of health policy analysis to (1) develop a preliminary synthesis of findings from selected frameworks and theories; (2) analyze relationships between elements of those frameworks and theories to construct an overarching framework for health policy analysis; and then, (3) apply that overarching framework to analyze tobacco control policies in Togo and in South Africa. This Comprehensive Framework for Multi-Sectoral Approach to Health Policy Analysis has 4 main constructs: context, content, stakeholders, and strategies. When applied to analyze tobacco control policy processes in Togo and in South Africa, it identified a shared goal in both countries to have a policy content that is compliant with the provisions of international tobacco treaties and differences in strategic interactions between institutions (e.g., tobacco industry, government structures) and in the political context of tobacco control policy process. These findings highlight the need for context-specific political mapping identifying the interests of all stakeholders and strategies for interaction between health and other sectors when planning policy formulation or implementation.

Assessment of the multi-sectoral approach to tobacco control policies in South Africa and Togo.

BACKGROUND: Tobacco use is the world's leading preventable cause of illness and death and the most important risk factor for non-communicable diseases (NCDs), particularly cardiovascular and chronic respiratory diseases (heart attack, stroke, congestive obstructive pulmonary disease, and lung cancer). Tobacco control is one of the World Health Organization's "best-buys" interventions to prevent NCDs. This study assessed the use of a multi-sectoral approach (MSA) in developing and implementing tobacco control policies in South Africa and Togo. METHODS: This two-country case study consisted of a document review of tobacco control policies and of key informant interviews (N = 56) about the content, context, stakeholders, and strategies employed throughout policy formulation and implementation in South Africa and Togo. To guide our analysis, we used the Comprehensive Framework for Multi-Sectoral Approach to Health Policy, which is built around four major constructs of context, content, stakeholders and strategies. RESULTS: The findings show that the formulation of tobacco control policies in both countries was driven locally by the political, historical, social and economic contexts, and globally by the adoption WHO Framework Convention on Tobacco Control (FCTC). In both countries, the health department led policy formulation and implementation. The stakeholders involved in South Africa were more diverse, proactive and dynamic than those in Togo, whereas the strategies employed were more straightforward in Togo than in South Africa. The extent of understanding and use of MSA in both countries consisted of an inter-sectoral action for health, whereby the health department strove to collaborate with other sectors within and outside the government. Consequently, information sharing was identified as the main outcome of the interactions between institutions and interest groups within and across three critical sectors of the state, namely the public (government), the private and the civil society. CONCLUSION: Tobacco control policies in South Africa and Togo were formulated and implemented from an inter-sectoral approach perspective, which relied heavily on information transfer between stakeholders and less on collaborative problem-solving approach. Incorporation of multiple stakeholders allowed both countries to formulate policies to meet FCTC goals for tobacco control and NCD reduction.

Perceptions of and support for national health insurance in South Africa's public and private healthcare sectors.

INTRODUCTION: For the purpose of effective implementation of a National Health Insurance (NHI) policy it is necessary to have an understanding of the awareness and perceptions of and support for such policy among clients using the healthcare system. METHODS: The South African National Health and Nutrition Examination Survey asked household heads a series of questions on healthcare utilisation and access and collected information on knowledge and perceptions of and support for national health insurance. Comparisons are drawn between private sector healthcare users with medical aid and public sector healthcare users without medical aid, using descriptive and regression analysis. RESULTS: Inequalities in access to quality healthcare remain stark. Only 8.5% of private users had postponed seeking healthcare compared to 23.9% of public users (p < 0.001). Only 11.9% of public users were very satisfied with the quality of healthcare services compared to 50.2% of private users (p < 0.001). More than eighty percent of healthcare users however were of the opinion that NHI is a top priority. However, for healthcare users to sacrifice choice required a national health insurance that provides better quality healthcare, increasing the probability of support for an NHI with lower cost and full coverage by 10.1%. CONCLUSION: It is imperative to provide better quality healthcare services in the public sector for private sector users to be supportive of national health insurance. Concerted efforts are also required to develop a proper communication strategy to disseminate information on and garner support for national health insurance, both in the public and private healthcare sectors.

Changing the policy for intermittent preventive treatment with sulfadoxine-pyrimethamine during pregnancy in Malawi.

BACKGROUND: The growing resistance of Plasmodium falciparum to sulfadoxine-pyrimethamine (SP) treatment for uncomplicated malaria led to a recommendation by the World Health Organization for the use of artemisinin-based combination therapy. Inevitably, concerns were also raised surrounding the use of SP for intermittent prevention treatment of malaria during pregnancy (IPTp) amidst the lack of alternative drugs. Malawi was the first country to adopt intermittent prevention treatment with SP in 1993, and updated in 2013. This case study examines the policy updating process and the contribution of research and key stakeholders to this process. The findings support the development of a malaria research-to-policy framework in Malawi. METHODS: Documents and evidence published from 1993 to 2012 were systematically reviewed in addition to key informant interviews. RESULTS: The online search identified 170 potential publications, of which eight from Malawi met the inclusion criteria. Two published studies from Malawi were instrumental in the WHO policy recommendation which in turn led to the updating of national policies. The updated policy indicates that more than two SP doses, as informed by research, overcome the challenges of the first policy of two SP doses only because of ineffectiveness by P. falciparum resistance and the global lack of replacement drugs to SP for IPTp. CONCLUSION: International WHO recommendations facilitated a smooth policy change driven by motivated local leadership with technical and financial support from development partners. Policy development and implementation should include key stakeholders and use local malaria research in a research-to-policy framework.

A cost analysis of a hospital-based palliative care outreach program: implications for expanding public sector palliative care in South Africa.

CONTEXT: Increasing access to palliative care services in low- and middle-income countries is often perceived as unaffordable despite the growing need for such services because of the increasing burden of chronic diseases including HIV and AIDS. OBJECTIVES: The aim of the study was to establish the costs and cost drivers for a hospital outreach palliative care service in a low-resource setting, and to elucidate possible consequential quality-of-life improvements and potential cost savings. METHODS: The study used a cost accounting procedure to cost the hospital outreach services--using a step-down costing method to measure unit (average) costs. The African Palliative Care Association Palliative Outcome Score (APCA POS) was applied at five intervals to a cohort of 72 consecutive and consenting patients, enrolled in a two-month period. RESULTS: The study found that of the 481 and 1902 patients registered for outreach and in-hospital visits, respectively, 4493 outreach hospital visits and 3412 in-hospital visits were done per year. The costs per hospital outreach visit and in-hospital visit were US$71 and US$80, respectively. The cost per outreach visit was 50% less than the average cost of a patient day equivalent for district hospitals of $142. Some of the POS of a subsample (n=72) showed statistically significant improvements. CONCLUSION: Hospital outreach services have the potential to avert hospital admissions in generally overcrowded services in low-resource settings and may improve the quality of life of patients in their home environments.
