- ItemBuilding capacity in clinical epidemiology in Africa : experiences from Masters programmes(BioMed Central, 2017-02-27) Young, Taryn; Naude, Celeste; Brodovcky, Tania; Esterhuizen, TonyaENGLISH SUMMARY : Background: To describe and contrast programmatic offering of Clinical Epidemiology Masters programmes in Africa, to evaluate experiences of graduates and faculty, and assess if graduates are playing roles in research, practice and teaching of Clinical Epidemiology. Methods: We searched and identified relevant programmes, reviewed programmatic documentation, interviewed convenors and surveyed graduates. Participants provided informed consent, interviews with faculty were recorded and transcribed for analysis purposes, and graduates participated in an online survey. Results: Five structured Masters programmes requiring health science professionals to complete modules and research projects were assessed. Demand for programmes was high. Graduates enjoyed the variety of modules, preferred blended teaching, and regarded assessments as fair. Graduates felt that career paths were not obvious after graduating. Despite this, some have gone on to promote and teach evidence-based health care, and conduct and disseminate research. Areas of concern raised by faculty were quality assurance; research project initiation, implementation and supervisory capacity; staff availability; funding to support implementation and lack of experiential learning. Conclusion: Although faced with challenges, these programmes build capacity of health professionals to practice in an evidence-informed way, and conduct rigorous research, which are central to advancing the practice of Clinical Epidemiology in Africa.
- ItemEvidence synthesis and translation for nutrition interventions to combat micronutrient deficiencies with particular focus on food fortification(MDPI, 2016) Lawrence, Mark; Wingrove, Kate; Naude, Celeste; Durao, SolangeOver two billion people suffer from micronutrient deficiencies. Food fortification is a prominent nutrition intervention to combat such deficiencies; however, its effectiveness, risks, and ethical implications vary depending on the contexts associated with the deficiency it is addressing and the circumstances with its implementation. The aim of this research was to analyse the profile of nutrition interventions for combating micronutrient deficiency with particular focus on food fortification reported in existing systematic reviews (SRs), guidelines and policy statements, and implementation actions for nutrition. A review of secondary data available from online databases of SRs, guidelines and policy statements, and implementation actions, categorised as either “nutrition-specific interventions” (NSpI) or “nutrition-sensitive interventions” (NSeI), was conducted. Currently, there is evidence available for a diversity of food fortification topics, and there has been much translation into action. Indeed, food fortification and micronutrient supplementation interventions and NSpI more broadly dominate the profile of interventions for which there were SRs, guidelines, and policy statements available. The findings demonstrate that, although there is a rational linear relationship between evidence synthesis and translation in formulating policy and actions to combat micronutrient deficiencies, the various nutrition interventions available to help combat micronutrient deficiencies are not equally represented in the evidence synthesis and translation processes. Effective and safe policies and actions to combat micronutrient deficiencies require decisions to be informed from a body of evidence that consists of evidence from a variety of interventions. Into the future, investment in making available a higher number of SRs, guidelines and policy statements, and actions of NSeI is indicated.
- ItemFruit and vegetable consumption by South African children, aged 12 to 108 months : a secondary analysis of the National Food Consumption Survey data(Stellenbosch : University of Stellenbosch, 2007-03) Naude, Celeste; Kruger, H. S.; Labadarios, D.; University of Stellenbosch. Faculty of Medicine and Health Sciences. Department of Interdisciplinary Health Sciences.INTRODUCTION: Epidemiologic research strongly supports the importance of adequate fruit and vegetable intake for the promotion of human health and the prevention of chronic disease. Data suggest that fruit and vegetable consumption in children may protect against an array of childhood illnesses. Low fruit and vegetable intake has been recognized as a key contributor to micronutrient deficiencies in developing countries. Evidence indicates that fruit and vegetable consumption is inadequate in both developed and developing nations. A paucity of data on fruit and vegetable consumption exists in South Africa. Quantification of fruit and vegetable consumption is important for the worldwide drive to increase consumption and for strategy development to address inadequate consumption. METHODS: A secondary analysis of the dietary intake data (24 hour recall questionnaire (24-H-RQ) and quantified food frequency questionnaire (QFFQ)), collected during the 1999 National Food Consumption Survey (NFCS) in 12 – 108 month old children in South Africa, was conducted to ...
- ItemPrevention and treatment of acute malnutrition in humanitarian emergencies : a multi-organisation collaboration to increase access to synthesised evidence(SpringerOpen (part of Springer Nature), 2019-05-31) Allen, Claire; Jansen, Jeroen; Naude, Celeste; Durao, Solange; Mehta, Monaz; Von Elm, Erik; Van Der Kam, Saskia; Prudhon, Claudine; Mayberry, Amy; McGrath, Marie; Alae-Carew, Carmelia; Berkley, James A.; Fracassi, Patrizia; Aburto, Nancy; Jenkins, Mica; Bourdaire, Jessica; Lang, Shona; Nevitte, Alex; Kuhn, Isla; Lee, Shaun; Hafezi, HannahBackground: Program decision-making to prevent and treat acute malnutrition in an emergency can be hampered by a lack of accessible and relevant overviews of directly available robust research evidence. There is often evidence from related settings such as from low-income countries, but this is dispersed across many databases, may be inaccessible and requires assessment of its relevance to the humanitarian setting. We describe a process whereby a multi-disciplinary, international group of specialists worked together to build relevant and effective collections of available systematic reviews on acute malnutrition, published and disseminated as online collections, to improve access to the evidence and concise, synthesised, relevant up to date evidence for programming. By describing this process, we hope to inspire other professional groups to take part in similar multi-stakeholder, multi-disciplinary projects. Objectives: This project was designed to make the evidence from relevant systematic reviews about malnutrition as accessible as possible to support evidence-based decision-making and to guide future research on the prevention and treatment of acute malnutrition in humanitarian emergencies. Methods: Between March 2017 and March 2018, a large group (21 volunteers and stakeholders) with different backgrounds collaborated to review and curate collections of systematic reviews of interventions for the prevention and treatment of moderate and severe acute malnutrition relevant to humanitarian emergencies. The methodology loosely followed general guidance for overviews of systematic reviews with a pre-defined question (formulated using the PICOS format) and search strategies applied to multiple databases. Pairs of collaborators first screened the search yields to identify potentially eligible reviews, where after other pairs screened the list of potentially eligible reviews for relevance and thus included in the final collections. Results: Search strategies were run in 12 databases, in the week of 15 September 2017, yielding a total of 4646 records after de-duplication. At this point, Cochrane reviews (n = 463) and non-Cochrane reviews (n = 4183) were separated and handled by different teams to compile three linked collections, namely the Evidence Aid Collection, consisting of relevant non-Cochrane reviews, and two Cochrane Special Collections, consisting of relevant Cochrane reviews, one for prevention and the other for treatment of acute malnutrition. The collections were published on the Evidence Aid website on 12 March 2018 and Cochrane website in August 2018. Discussion: Through this collaboration, we have successfully generated three collections of systematic reviews to guide prevention and management of acute malnutrition in humanitarian emergencies: an Evidence Aid collection of non-Cochrane reviews, and two Cochrane Special Collections of Cochrane reviews. These collections provide accessible synthesised evidence that can be used to inform decision-making on strategies and policies in the humanitarian emergency and disaster risk reduction sectors and to guide future research by identifying gaps in robust evidence and areas that are under-researched. These collections did not set out to assess methodological quality, appraise in detail what the reviews found or summarise the evidence, but rather to curate the identified relevant systematic reviews into online resources for others to use. This unique collaboration of different individuals, organisations and stakeholders, and the collation of robust evidence can be repeated for other subjects, and Evidence Aid is eager to support new collections around other topics relevant to humanitarian emergencies.
