Transitioning food environments and diets of African migrants: implications for non-communicable diseases

3rd International Symposium on Nutrition: ‘Urban food policies for sustainable nutrition and health’, online conference, 27-28 January 2022.Symposium one: Better understanding urban nutrition and health problems and understanding their causeInternational audienceNon-communicable diseases disproportionately affect African migrants from sub-Saharan Africa living in high-income countries (HICs). Evidence suggests this is largely driven by forces that include migration, globalisation of unhealthy lifestyles (poor diet, physical inactivity and smoking), unhealthy food environments, socioeconomic status and population ageing. Changes in lifestyle behaviours that accompany migration are exemplified primarily by shifts in dietary behaviours from more traditional diets to a diet that incorporates that of the host culture, which promotes the development of obesity, diabetes, hypertension and CVD. The current paper presents a critical analysis of dietary change and how this is influenced by the food environment and the socioeconomic context following migration. We used a food systems framework to structure the discussion of the interaction of factors across the food system that shape food environments and subsequent dietary changes among African migrant populations living in HICs
