Petrikova I, Bhattacharjee R, Fraser PD. The 'Nigerian Diet' and Its Evolution: Review of the Existing Literature and Household Survey Data. Foods 2023; 12:443.

Abstract
Natural and social science studies have commonly referenced a 'typical' or 'habitual' Nigerian diet, without defining what such a diet entails. Our study, based on a systematic review of the existing literature and an analysis of household-level survey data, describes the general outline of a common Nigerian diet and how it varies based on spatial, demographic, and socio-economic characteristics. We further try to establish whether Nigeria has embarked on a dietary transition common in most modern economies, marked by a greater consumption of processed foods, fats, and sugar at the expense of traditional whole cereals and pulses. We conclude that while a traditional Nigerian diet is still relatively healthy from an international perspective, it has indeed been transitioning, with an increasing inclusion of high-energy, high-fat, and high-sugar processed foods and a related growing incidence of overweight, obesity, and diet-related non-communicable diseases.

Hawwash D, Pinxten W, Raneri JE, Kolsteren P, Lachat C. Uptake and impact of priority setting exercises in nutrition research publications. Eur J Clin Nutr 2020; 75:198-208. [PMID: 32855521 DOI: 10.1038/s41430-020-00729-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 07/01/2020] [Accepted: 08/07/2020] [Indexed: 11/09/2022]
Abstract
OBJECTIVE To assess how priority setting exercises for nutrition research are considered in publication. DESIGN Cross-sectional design. SETTINGS First, a citation analysis of priority setting exercises found in nutrition research until 2019 was conducted. The reasons for citation were extracted from the text of citing papers and the reasons were defined as: (i) acting on the research questions identified as priorities, (ii) acknowledging the priority setting exercise, (iii) using the same method, or (iv) previous knowledge to support evidence. Second, a survey with authors of the priority setting exercises was done to understand priority setters' perspectives on the impact and satisfaction of their work. PARTICIPANTS Twenty-one priority setting exercise papers were included. In all, 434 citing papers were found, of which 338 were considered in the citation analysis. A sample of 17 authors representing 13 priority setting exercise papers completed the impact and satisfaction survey. RESULTS Half of the priority setting exercise papers were published by 2013. After excluding self-citations (n = 60), the priority setting papers had on average 18 citations. Priority setting exercises had a median of 1 (IQR = 0-1) citing manuscript that acted on the recommendations produced from priority setting exercises. Authors of the priority setting exercises expressed a desire for increased uptake of the results of the priority setting exercises by funding agencies. Key barriers for uptake were identified as challenges in involving stakeholders and the general public for participation in the priority setting exercise. CONCLUSIONS Priority settings exercises are important efforts to guide nutrition research toward effective allocation of resources. However, there seems to be a limited consideration of these priority setting exercises in research papers.

HEALTH ECONOMICS 2020; 29:945-954. [PMID: 32412153 PMCID: PMC7383734 DOI: 10.1002/hec.4029] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Revised: 03/11/2020] [Accepted: 04/14/2020] [Indexed: 05/07/2023]
Abstract
As economic evaluation becomes increasingly essential to support universal health coverage (UHC), we aim to understand the growth, characteristics, and quality of cost-effectiveness analyses (CEA) conducted for Africa and to assess institutional capacity and relationship patterns among authors. We searched the Tufts Medical Center CEA Registries and four databases to identify CEAs for Africa. After extracting relevant information, we examined study characteristics, cost-effectiveness ratios, individual and institutional contribution to the literature, and network dyads at the author, institution, and country levels. The 358 identified CEAs for Africa primarily focused on sub-Saharan Africa (96%) and interventions for communicable diseases (77%). Of 2,121 intervention-specific ratios, 8% were deemed cost-saving, and most evaluated immunizations strategies. As 64% of studies included at least one African author, we observed widespread collaboration among international researchers and institutions. However, only 23% of first authors were affiliated with African institutions. The top producers of CEAs among African institutions are more adherent to methodological and reporting guidelines. Although economic evidence in Africa has grown substantially, the capacity for generating such evidence remains limited. Increasing the ability of regional institutions to produce high-quality evidence and facilitate knowledge transfer among African institutions has the potential to inform prioritization decisions for designing UHC.

Abstract
OBJECTIVES The aim of this study was to characterise the local foods and beverages sold and advertised in three deprived urban African neighbourhoods. DESIGN Cross-sectional observational study. We undertook an audit of all food outlets (outlet type and food sold) and food advertisements. Descriptive statistics were used to summarise exposures. Latent class analysis was used to explore the interactions between food advertisements, food outlet types and food type availability. SETTING Three deprived neighbourhoods in African cities: Jamestown in Accra, Ho Dome in Ho (both Ghana) and Makadara in Nairobi (Kenya). MAIN OUTCOME MEASURE Types of foods and beverages sold and/or advertised. RESULTS Jamestown (80.5%) and Makadara (70.9%) were dominated by informal vendors. There was a wide diversity of foods, with high availability of healthy (eg, staples, vegetables) and unhealthy foods (eg, processed/fried foods, sugar-sweetened beverages). Almost half of all advertisements were for sugar-sweetened beverages (48.3%), with higher exposure to alcohol adverts compared with other items as well (28.5%). We identified five latent classes which demonstrated the clustering of healthier foods in informal outlets, and unhealthy foods in formal outlets. CONCLUSION Our study presents one of the most detailed geospatial exploration of the urban food environment in Africa. The high exposure of sugar-sweetened beverages and alcohol both available and advertised represent changing urban food environments. The concentration of unhealthy foods and beverages in formal outlets and advertisements of unhealthy products may offer important policy opportunities for regulation and action.

Abstract
Although substantial amount of nutrition research is conducted in Africa, the research agenda is mainly donor-driven. There is a clear need for a revised research agenda in Africa which is both driven by and responding to local priorities. The present paper summarises proceedings of a symposium on how evidence can guide decision makers towards context-appropriate priorities and decisions in nutrition. The paper focuses on lessons learnt from case studies by the Evidence Informed Decision Making in Nutrition and Health Network implemented between 2015 and 2016 in Benin, Ghana and South Africa. Activities within these countries were organised around problem-oriented evidence-informed decision-making (EIDM), capacity strengthening and leadership and horizontal collaboration. Using a combination of desk-reviews, stakeholder influence-mapping, semi-structured interviews and convening platforms, these country-level studies demonstrated strong interest for partnership between researchers and decision makers, and use of research evidence for prioritisation and decision making in nutrition. Identified capacity gaps were addressed through training workshops on EIDM, systematic reviews, cost-benefit evaluations and evidence contextualisation. Investing in knowledge partnerships and development of capacity and leadership are key to drive appropriate use of evidence in nutrition policy and programming in Africa.

Gaps and opportunities for nutrition research in relation to non-communicable diseases in Arab countries: Call for an informed research agenda. Nutr Res 2017; 47:1-12. [PMID: 29241573 DOI: 10.1016/j.nutres.2017.07.011] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2017] [Revised: 07/27/2017] [Accepted: 07/31/2017] [Indexed: 10/19/2022]
Abstract
Effective public health nutrition interventions are needed to curb the escalating prevalence of non-communicable diseases (NCDs) in many Arab countries. In order to generate the scientific evidence needed for the success of these interventions, an informed research agenda should be developed. The purpose of this review is to identify gaps and opportunities for research on nutrition and NCDs among Arab countries, which is an important step towards the formulation of this research agenda. Published papers that addressed nutrition and NCDs in Arab countries between the years 2006 and 2015 were reviewed (n=824). The main gaps identified were related to the predominance of laboratory-based studies with few cohort and intervention studies, and the small percentage of articles examining dietary patterns. While food frequency questionnaires were the main dietary assessment method used, only 35% were validated. Very few studies included children and the majority considered nutrition in isolation, excluding other environmental factors. Opportunities identified included the promising momentum in studying nutrition and NCDs among Arab countries, evidenced by an increasing number of articles published over the years, that may be guided in future nutrition research to fill the identified gaps. In addition, the higher number of articles in high-income countries coupled with the impact of papers in middle-income countries suggests an opportunity of synergistic collaboration among these countries. The identified gaps and opportunities in this review may serve as basis for Arab countries to start developing a research agenda in the area of nutrition and NCDs.

Abstract
BACKGROUND Collaboration between Sub-Saharan African researchers is important for the generation and transfer of health technology assessment (HTA) evidence, in order to support priority-setting in health. The objective of this analysis was to evaluate collaboration patterns between countries. METHODS We conducted a rapid evidence assessment that included a random sample of health economic evaluations carried out in 20 countries (Angola, Botswana, Congo, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Swaziland, Tanzania, Zambia, Zimbabwe, Ghana, Kenya, Nigeria, Ethiopia, Uganda). We conducted bibliometric network analysis based on all first authors with a Sub-Saharan African academic affiliation and their co-authored publications ("network-articles"). Then we produced a connection map of collaboration patterns among Sub-Saharan African researchers, reflecting the number of network-articles and the country of affiliation of the main co-authors. RESULTS The sample of 119 economic evaluations mostly related to treatments of communicable diseases, in particular HIV/AIDS (42/119, 35.29 %) and malaria (26/119, 21.85 %). The 39 first authors from Sub-Saharan African institutions together co-authored 729 network-articles. The network analysis showed weak collaboration between health economic researchers in Sub-Saharan Africa, with researchers being more likely to collaborate with Europe and North America than with other African countries. South Africa stood out as producing the highest number of health economic evaluations and collaborations. CONCLUSIONS The development and evaluation of HTA research networks in Sub-Saharan Africa should be supported, with South Africa central to any such efforts. Organizations and institutions from high income countries interested in supporting priority setting in Sub-Saharan Africa should include promoting collaboration as part of their agendas, in order to take advantage of the potential transferability of results and methods of the available health economic analyses in Africa and internationally.
