Item The African urban food environment framework for creating healthy nutrition policy and interventions in urban Africa(PLOS ONE, 2021) Osei-Kwasi, H.A.; Laar, A.; Zotor, F.; Pradeilles, R.; Aryeetey, R.; Green, M.; Griffiths, P.; Akparibo, R.; Wanjohi, M.N.; Rousham, E.; Barnes, A.; Booth, A.; Mensah, K.; Asiki, G.; Kimani-Murage, E.; Bricas, N.; Holdsworth, M.This study developed, validated, and evaluated a framework of factors influencing dietary behaviours in urban African food environments, to inform research prioritisation and inter vention development in Africa. A multi-component methodology, drawing on concept map ping, was employed to construct a framework of factors influencing dietary behaviours in urban Africa. The framework adapted a widely used socio-ecological model (developed in a high-income country context) and was developed using a mixed-methods research approach that comprised: i. Evidence synthesis consisting of a systematic review of 39 papers covering 14 African countries; ii. Qualitative interview data collected for adolescents and adults (n = 144) using photovoice in urban Ghana and Kenya; and iii. Consultation with interdisciplinary African experts (n = 71) from 27 countries, who contributed to at least one step of the framework (creation, validation/evaluation, finalisation). The final framework included 103 factors influencing dietary behaviours. Experts identified the factors influencing dietary behaviours across all the four levels of the food environment i.e. the individual, social, physical and macro levels. Nearly half (n = 48) were individual-level factors and just under a quarter (n = 26) were at the macro environmental level. Fewer factors associated with social (n = 15) and physical (14) environments were identified. At the macro level, the factors ranked as most important were food prices, cultural beliefs and seasonality. Factors ranked as important at the social level were household composition, family food habits and dietary practices. The type of food available in the neighbourhood and convenience were seen as important at the physical level, while individual food habits, food preferences and socioeconomic status were ranked highly at the individual level. About half of the factors (n = 54) overlap with those reported in an existing socio-ecological food environment framework developed in a high-income country context. A further 49 factors were identified that were not reported in the selected high-income country framework, underlining the importance of contextualisation. Our conceptual framework offers a useful tool for research to understand dietary transitions in urban African adolescents and adults, as well as identification of factors to intervene when promoting healthy nutritious diets to prevent multiple forms of malnutrition.Item Food Security in Ghanaian Urban Cities: A Scoping Review of the Literature(nutrients, 2021) Akparibo, R.; Aryeetey, R.N.O.; Asamane, E.A.; Osei-Kwasi, H.A.; Ioannou, E.; Solar, G.I; Cormie, V.; Pereko, K.K.; Amagloh, F.K.; Caton, S.J.; Cecil, J.E.Urbanisation in Ghana could be negatively impacting the state of food security, especially in economically vulnerable groups. Food supply, safety, and quality are all aspects of food security which could be impacted. We conducted a scoping literature review to understand the nature and magnitude of evidence available on the urban food security situation in Ghana. A literature search was conducted in Medline, CINAHL, Embase, Global Health, Scopus,Web of Science, AfricaWide Information and Google Scholar to identify relevant peer-reviewed and grey literature. 45 studies, mainly cross-sectional surveys/food samples analysis, met the inclusion criteria. The majority of studies were concentrated in the Greater Accra Region (n = 24). Most studies focused on food safety and quality (n = 31). Studies on supply and stability were, however, scarce. Qualitative research methods were uncommon in the included studies. The existing literature on food security are concentrated in two regions: The Greater Accra and Ashanti regions. Future studies exploring food security in urban Ghana should focus on exploring the lived experiences and perceptions of food insecurity and food stability by urban-dwellers using qualitative methods. The evidence suggesting that the safety/quality of foods sold in Ghanaian markets is poor should be a concern to consumers and policy makers.
