Given the complexity of global health crises such as the COVID-19 pandemic, it is typical for crisis-focused interventions to have a multiplicity of impacts. Some of these impacts may yield positive or negative externalities for health priorities that do not have the same perceived urgency. The interplay between COVID-19 prevention (a high priority, high perceived urgency issue) and non-communicable disease (NCD) prevention (a high priority, low perceived urgency issue) provides a good case in point. By analysing tweets during Nigeria’s COVID-19 lockdowns, we identified avenues for social media to help adapt crisis responses to a wider range of wellbeing concerns.

We highlight aspects of the ordinary – known interactions between urban environments and physical activity – that are amplified by the extraordinary – the COVID-19 pandemic in Lagos, Nigeria. Leisu...

Physical inactivity is increasing in low- and middle-income countries (LMICs), where noncommunicable diseases (NCDs), urbanisation and sedentary living are rapidly growing in tandem. Increasing active living requires the participation of multiple sectors, yet it is unclear whether physical activity (PA)-relevant sectors in LMICs are prioritising PA. We investigated to what extent sectors that influence PA explicitly integrate it in their policies in an LMIC such as Cameroon. We systematically identified policy documents relevant to PA and NCD prevention in Cameroon; and using the Walt and Gilson policy triangle we described, analysed, and interpreted the policy contexts, contents, processes, and actors. We found 17 PA and NCD policy documents spanning from 1974 to 2019 across seven ministries. Thirteen (13/17) policies targeted infrastructure improvement, and four (4/17) targeted communication for behaviour change, all aiming to enhance leisure domain PA. Only the health sector explicitly acknowledged the role of PA in NCD prevention. Notably, no policy from the transport sector mentioned PA. Our findings highlight the need for intersectoral action to integrate PA into policies in all relevant sectors. These actions will need to encompass the breadth of PA domains, including transport, while emphasising the multiple health benefits of PA for the population.

Funder: National Institute for Health Research; Grant(s): GHR:16/137/34, Noncommunicable diseases contribute the greatest to global mortality. Unhealthy diet���a prominent risk factor���is intricately linked to urban built and food environments and requires intersectoral efforts to address. Framings of the noncommunicable disease problem and proposed solutions within global and African regional diet-related policy documents can reveal how amenable the policy landscape is for supporting intersectoral action for health in low-income to middle-income countries. This study applied a document analysis approach to undertake policy analysis on global and African regional policies related to noncommunicable disease and diet. A total of 62 global and 29 African regional policy documents were analysed. Three problem frames relating to noncommunicable disease and diet were identified at the global and regional level, namely evidence-based, development, and socioeconomic frames. Health promotion, intersectoral and multisectoral action, and evidence-based monitoring and assessment underpinned proposed interventions to improve education and awareness, support structural changes, and improve disease surveillance and monitoring. African policies insufficiently considered associations between food security and noncommunicable disease. In order to effectively address the noncommunicable disease burden, a paradigm shift from ���health for development��� to ���development for health��� is required across non-health sectors. Noncommunicable disease considerations should be included within African food security agendas, using malnutrition as a possible intermediary concept to motivate intersectoral action to improve access to nutritious food in African low-income to middle-income countries.

Funder: National Institute for Health Research (NIHR); Grant(s): GHR: 16/137/34), 16/137/34, Rates of obesity and related non-communicable diseases are on the rise in sub-Saharan Africa, associated with sub-optimal diet and physical inactivity. Implementing evidence-based interventions targeting determinants of unhealthy eating and physical inactivity in children and adolescents' immediate environments is critical to the fight against obesity and related non-communicable diseases. Setting priorities requires a wide range of stakeholders, methods, and context-specific data. This paper reports on a novel participatory study design to identify and address contextual drivers of unhealthy eating and physical inactivity of children and adolescents in school and in their home neighborhood food and built environments. We developed a three-phase mixed-method study in Cameroon (Yaoundé) and South Africa (Johannesburg and Cape Town) from 2020-2021. Phase one focused on identifying contextual drivers of unhealthy eating and physical inactivity in children and adolescents in each setting using secondary analysis of qualitative data. Phase two matched identified drivers to evidence-based interventions. In phase three, we worked with stakeholders using the Delphi technique to prioritize interventions based on perceived importance and feasibility. This study design provides a rigorous method to identify and prioritize interventions that are tailored to local contexts, incorporating expertise of diverse local stakeholders.

La pandémie à Coronavirus 2019 (COVID-19) touche les pays d´Afrique sub-Saharienne depuis le mois de mars 2020. Au-delà des désastres sanitaire et économique causés, se pose un problème psycho-socio-culturel en rapport avec la gestion des corps de personnes décédées de cette maladie; ce problème est susceptible d´entraver la bonne marche de la stratégie de riposte. Au Cameroun par exemple, la gestion actuelle de ces dépouilles ne fait pas l´unanimité. En effet, les restrictions appliquées à l´inhumation, bien que récemment assouplies proscrivent entre autres tout transfert interurbain des dépouilles. A la lumière des considérations culturelles africaines de la personne décédée, des dissensions créées entre les familles et le corps médical, de la législation et des données scientifiques disponibles, cet article analyse les risques et les bénéfices de l´inhumation des dépouilles par les familles. Il propose ensuite des solutions qui concilient la dignité (en laissant les familles enterrer leurs morts dans les domiciles), et la sécurité (en assurant une conservation hermétique et la surveillance d´un officier de police judiciaire). L´application de ces solutions pourraient améliorer la confiance de la population envers le système de santé et contribuer positivement aux stratégies de prévention, d´identification et de prise en charge des cas de COVID-19.

This review seeks to address knowledge gaps around the economic burden of diabetes in Africa. Africa is home to numerous endemic infections and also prevalent non-communicable diseases including diabetes. It is projected that the greatest increases in diabetes prevalence will occur in Africa. The importance of this review therefore lies in providing adequate knowledge on the economic challenges that diabetes poses to the continent and describe the way forward in tackling this epidemic. Diabetes contributes to a huge amount of the global health expenditure in the world. There is a dearth of information on the economic burden of diabetes in Africa with very limited number of studies in the area. Predictions do show that Africa has the greatest predicted increase in both the burden of diabetes and associated diabetic complications but yet contributes the lowest in the global annual healthcare expenses with regard to diabetes care. In 2017, the International Diabetes Federation (IDF) estimated the total health expenditure due to diabetes at $3.3 billion. In Nigeria, the national annual direct costs of diabetes was estimated in the range of $1.071 billion to $1.639 billion per year while the estimated monthly direct medical costs per individual in Cameroon stands at $148. In Sudan, the direct cost of type 2 diabetes control was $175 per year which only included the cost of medications and ambulatory care. People with diabetes are likely to experience one or more chronic illness and a significant portion of the costs associated with these complications are attributed to the underlying diabetes. The growing epidemics of diabetes and associated diabetic complications worldwide poses catastrophic financial costs, especially in Africa where most of the expenses are paid by patients and families. The most common method used for the estimation of the economic burden of a public health problem like diabetes is the cost-of-illness approach. Cost-of-illness studies traditionally divide costs into three categories: direct, indirect, and intangible. The IDF estimated the total health expenditure due to diabetes at $3.3 billion worldwide in 2017. Most of the existing studies in Africa estimated only the direct costs. The medical direct cost of type 1 diabetes was higher than type 2. However, the estimations of costs of diabetes in many countries in Africa may be underestimated due to absence of data on the relative contribution of cost of diabetes complications.

Background The rise of non-communicable diseases (NCDs) in Africa requires a multi-sectoral action (MSA) in their prevention and control. This study aimed to generate evidence on the extent of MSA application in NCD prevention policy development in five sub-Saharan African countries (Kenya, South Africa, Cameroon, Nigeria and Malawi) focusing on policies around the major NCD risk factors. Methods The broader study applied a multiple case study design to capture rich descriptions of policy contents, processes and actors as well as contextual factors related to the policies around the major NCD risk factors at single- and multi-country levels. Data were collected through document reviews and key informant interviews with decision-makers and implementers in various sectors. Further consultations were conducted with NCD experts on MSA application in NCD prevention policies in the region. For this paper, we report on how MSA was applied in the policy process. Results The findings revealed some degree of application of MSA in NCD prevention policy development in these countries. However, the level of sector engagement varies across different NCD policies, from passive participation to active engagement, and by country. There was higher engagement of sectors in developing tobacco policies across the countries, followed by alcohol policies. Multi-sectoral action for tobacco and to some extent, alcohol, was enabled through established structures at national levels including inter-ministerial and parliamentary committees. More often coordination was enabled through expert or technical working groups driven by the health sectors. The main barriers to multi-sectoral action included lack of awareness by various sectors about their potential contribution, weak political will, coordination complexity and inadequate resources. Conclusion MSA is possible in NCD prevention policy development in African countries. However, the findings illustrate various challenges in bringing sectors together to develop policies to address the increasing NCD burden in the region. Stronger coordination mechanisms with clear guidelines for sector engagement are required for effective MSA in NCD prevention. Such a mechanisms should include approaches for capacity building and resource generation to enable multi-sectoral action in NCD policy formulation, implementation and monitoring of outcomes.

International audience; Background: Tobacco use is the leading cause of preventable death in the world today. In 2010, the World Health Organization (WHO) proposed efficient and inexpensive "best buy" interventions for prevention of tobacco use including: tax increases, smoke-free indoor workplaces and public places, bans on tobacco advertising, promotion and sponsorship, and health information and warnings. This paper analyzes the extent to which tobacco use prevention policies in Cameroon align with the WHO tobacco "best buy" interventions. It further explores the context, content, formulation and implementation level of these policies. Methods: This was a case study combining a structured review of 19 government policy documents related to tobacco use and prevention, in-depth interviews with 38 key stakeholders and field observations. The Walt and Gilson's policy analysis triangle was used to describe and interpret the context, content, processes and actors during the formulation and implementation of tobacco prevention and control policies. Direct observations ascertained the level of implementation of some selected policies. Results: Twelve out of 19 policies for tobacco use and prevention address the WHO "best buy" interventions. Cameroon policy formulation was driven locally by the social context of non-communicable diseases, and globally by the adoption of the WHO Framework Convention on Tobacco Control. These policies incorporated at a certain level all four domains of tobacco use "best buy" interventions. Formulating policy on smoke-free areas was single-sector oriented, while determining tobacco taxes and health warnings was more complex utilizing multisectoral approaches. The main actors involved were ministerial departments of Health, Education, Finances, Communication and Social Affairs. The level of implementation varied widely from one policy to another and from one region to another. Political will, personal motivation and the existence of formal exchange platforms facilitated policy formulation and implementation, while poor resource allocation and lack of synergy constituted barriers. Conclusions: Despite actions made by the Government, there is no real political will to control tobacco use in Cameroon. Significant shortcomings still exist in developing and/or implementing comprehensive tobacco use and prevention policies. These findings highlight major gaps as well as opportunities that can be harnessed to improve tobacco control in Cameroon.

Background The increasing burden of non-communicable diseases (NCDs) in sub-Saharan Africa is causing further burden to the health care systems that are least equipped to deal with the challenge. Countries are developing policies to address major NCD risk factors including tobacco use, unhealthy diets, harmful alcohol consumption and physical inactivity. This paper describes NCD prevention policy development process in five African countries (Kenya, South Africa, Cameroon, Nigeria, Malawi), including the extent to which WHO “best buy” interventions for NCD prevention have been implemented. Methods The study applied a multiple case study design, with each country as a separate case study. Data were collected through document reviews and key informant interviews with national-level decision-makers in various sectors. Data were coded and analyzed thematically, guided by Walt and Gilson policy analysis framework that examines the context, content, processes and actors in policy development. Results Country-level policy process has been relatively slow and uneven. Policy process for tobacco has moved faster, especially in South Africa but was delayed in others. Alcohol policy process has been slow in Nigeria and Malawi. Existing tobacco and alcohol policies address the WHO “best buy” interventions to some extent. Food-security and nutrition policies exist in almost all the countries, but the “best buy” interventions for unhealthy diet have not received adequate attention in all countries except South Africa. Physical activity policies are not well developed in any study countries. All have recently developed NCD strategic plans consistent with WHO global NCD Action Plan but these policies have not been adequately implemented due to inadequate political commitment, inadequate resources and technical capacity as well as industry influence. Conclusion NCD prevention policy process in many African countries has been influenced both by global and local factors. Countries have the will to develop NCD prevention policies but they face implementation gaps and need enhanced country-level commitment to support policy NCD prevention policy development for all risk factors and establish mechanisms to attain better policy outcomes while considering other local contextual factors that may influence policy implementation such as political support, resource allocation and availability of local data for monitoring impacts.

The Analysis of Non-Communicable Disease Policies in Africa study was funded by the International Development Research Centre (grant # 107209–001) through the Africa Population Health Research Centre in Nairobi, Kenya. Publication charges were paid by the International Development Research Centre. Background: The World Health Organization’s Framework Convention on Tobacco Control, enforced in 2005, was a watershed international treaty that stipulated requirements for signatories to govern the production, sale, distribution, advertisement, and taxation of tobacco to reduce its impact on health. This paper describes the timelines, context, key actors, and strategies in the development and implementation of the treaty and describes how six sub-Saharan countries responded to its call for action on tobacco control. Methods: A multi-country policy review using case study design was conducted in Cameroon, Kenya, Nigeria, Malawi, South Africa, and Togo. All documents related to the WHO Framework Convention on Tobacco Control and individual country implementation of tobacco policies were reviewed, and key informant interviews related to the countries’ development and implementation of tobacco policies were conducted. Results: Multiple stakeholders, including academics and activists, led a concerted effort for more than 10 years to push the WHO treaty forward despite counter-marketing from the tobacco industry. Once the treaty was enacted, Cameroon, Kenya, Nigeria, Malawi, South Africa, and Togo responded in unique ways to implement tobacco policies, with differences associated with the country’s socio-economic context, priorities of country leaders, industry presence, and choice of strategies. All the study countries except Malawi have acceded to and ratified the WHO tobacco treaty and implemented tobacco control policy. Conclusions: The WHO Framework Convention on Tobacco Control provided an unprecedented opportunity for global action against the public health effects of tobacco including non-communicable diseases. Reviewing how six sub-Saharan countries responded to the treaty to mobilize resources and implement tobacco control policies has provided insight for how to utilise international regulations and commitments to accelerate policy impact on the prevention of non-communicable diseases.

Introduction : numerous studies have shown that diabetes reduces health-related quality of life (HRQoL), but little is known about the association between diabetes, HRQoL and productivity in developing countries. This study aimed toassess the impact of type 2 diabetes on the HRQoL and the ability to work of people with type 2 diabetes (T2D) in Yaounde, Cameroon. Methods : we conducted a cross-sectional study comparing the HRQoL and the ability to work, school and eat, in 500 people with T2D attending diabetes outpatient units of three hospitals in Yaounde and 500 people without diabetes matched for age, sex and residence. We performed multivariate logistic and linear regressions to assess the effect of diabetes on HRQoL (using Health Utilities Index Mark 3 scores) andability to work. In analyzing the effect of diabetes on HRQoL, we adjusted HUI scores for socio-demographic characteristicsand the number of comorbidities. Results : the overall unadjusted HUI3 mean score was significantly lower in people with T2D compared to people without diabetes (0.507 ± 0.333 vs. 0.725 ± 0.231, p Conclusion : type 2 diabetes had a negative impact on the HRQoL and the ability to work of people with diabetes in this African population, Cameroon. A better understanding of the impact of diabetes on patients and families can be an important tool for policy makers to undertake evidence-based actions.

Background The increasing numbers of people with type 2 diabetes (T2D) is a global concern and especially in sub-Saharan Africa, where diabetes must compete for resources with communicable diseases. Diabetes intensifies health care utilisation and leads to an increase in medical care costs. However, In Cameroon like in most developing countries, data on the impact of diabetes on the medical health system are scarce. We aimed to analyse the use of medical services and medicines attributable to T2D care in Yaoundé, Cameroon. Methods We conducted a cross-sectional study comparing the use of medical services and medicines on 500 people with T2D attending the diabetic outpatient units of three hospitals in Yaoundé and 500 people without diabetes matched for age, sex and residence. We performed multivariate logistic and quantile regressions to assess the effect of diabetes on the use of medical services and medicines and the presence of other chronic health problems. Models were adjusted for age, educational level, marital status, occupation and family income. Results Overall, the rate of use of health services was found to be greater in people with T2D than those without diabetes. People with T2D had greater odds of having an outpatient visit to any clinician (OR 97.1 [95% CI: 41.6–226.2]), to be hospitalised (OR 11.9 [95% CI: 1.6–87.9]), to take at least one medicine (OR 83.1 [37.1–185.8]) compared with people without diabetes. We also observed an association between diabetes and some chronic diseases/diabetes complications including hypertension (OR 9.2 [95% CI: 5.0–16.9]), cardiovascular diseases (OR 1.9 [95% CI: 0.8–4.9]), peripheral neuropathy (OR 6.2 [95% CI: 3.4–11.2]), and erectile dysfunction (OR 5.8 [95% CI: 2.7–12.1]). Conclusions This study showed that the presence of diabetes is associated with an increased use of health care services and medicines as well as with some chronic diseases/diabetes complications.

BackgroundAlthough the large majority of persons with diabetes and other non-communicable diseases (NCDs) lives and dies in low- and middle-income countries, the prevention and treatment of diabetes and other NCDs is widely neglected in these areas. A contributing reason may be that, unlike the impacts of acute and communicable diseases, the demands on resources imposed by diabetes is not superficially obvious, and studies capable of detecting these impacts have not be done.MethodsTo ascertain recent use of medical services and medicines and other information about the impact of ill-health, we in 2008-2009 conducted structured, personal interviews with 1,780 persons with diagnosed diabetes (DMs) and 1,770 matched comparison subjects (MCs) without diabetes in Cameroon, Mali, Tanzania and South Africa. We sampled DMs from diabetes registries and, in Cameroon and South Africa, from attendees at outpatient diabetes clinics. To recruit MCs, we asked subjects with diabetes to identify five persons living nearest to them who were of the same sex and approximate age. We estimated diabetes impact on medical services use by calculating ratios and differences between DMs and MCs, testing for statistical significance using two-stage multivariable hurdle models.FindingsDMs consumed 12.95 times more days of inpatient treatment, 7.54 times more outpatient visits, and 5.61 times more medications than MCs (all pConclusionsIn Sub-Saharan Africa, the relative incremental use of medical care and medicines associated with diagnosed diabetes is much greater than in industrialized countries and in China. Published calculations of the health-system impact of diabetes in Africa are dramatic underestimates. Although non-communicable diseases like diabetes are commonly thought to be minor problems for health systems and patients in Africa, our data demonstrate the opposite.

Public spaces have the potential to produce equitable improvements in population health. This mixed-methods systematic review aims to understand the components of, determinants, risks, and outcomes associated with public space initiatives in African cities. This study will include quantitative and qualitative study designs that describe public space initiatives in African cities with implications for promoting health and wellbeing, particularly through the prevention of noncommunicable diseases. Only studies published after 1990 and that contain primary or secondary data will be included in the review. Literature search strategies will be developed with a medical librarian. We will search PubMed, using both text words and medical subject headings. We will adapt this search to Scopus, Global Health, and Web of Science. This systematic review will adopt a mixed methods analytical approach. Mixing will occur in extracting both qualitative and quantitative findings; in synthesizing findings; and in the analysis where we will integrate the qualitative and quantitative strands. The learnings from this study will contribute to advancing knowledge on noncommunicable disease prevention through public space initiatives in African cities.
