Factors influencing the acceptance or rejection of dietary and body norm systems favorable to the prevention and control of type 2 diabetes among Sub-Saharan Africa migrants: A scoping review protocol

Background: The number of people living with type 2 diabetes (T2D) is increasing worldwide. The prevalence rate of this disease is generally higher in the migrant population compared to the general population. However significant inequalities in the prevalence of T2D are notable between and within migrant populations. Among them, migrants from sub-Saharan Africa, South America and South Asia are more affected than those of European origin. The act of eating and the corporality play an essential role in the development of this disease. Dietary and body norms systems favorable to the prevention and control of type 2 go against what is vital for most of these people, exposing them to conflicts of norms that are difficult to reconcile. 

Objectif: to identify factors that may influence the acceptance or rejection of dietary and body norm systems favorable to the prevention and control of T2D by Sub-Saharan Africa migrants living with T2D. 

Materials and methods: Scoping review according to the steps described by Arksey and O’Malley (2005) will be conducted. An electronic search of studies from 2011 to 2022, published English, Italian, French or in Portuguese will be conducted in eight databases (CINAHL, Cochrane library, Embase, Google Scholar, PsycInfo, PubMed, Scopus, and Web of Sciences). The grey literature including publication in Open Grey database and Website of non-governmental organizations working on migrant from Sub-Saharan Africa will be searched. All articles related to body norms, dietary behaviors, or determinants of body behaviors and dietary of migrants from Sub-Saharan Africa and those related to factors that influence acceptance or rejection of dietary and body norms systems favorable to the prevention and control of T2D among the migrants from Sub-Saharan Africa living with T2D or at risk to develop this disease will be included. This scoping review will be reported following the Standard Protocol Items: Recommendations for interventional Trials (SPIRIT) and Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. 

Results: The results will focus on factors influencing the acceptance or rejection of dietary and body norms systems favorable to the prevention and control of T2D among the migrants from Sub-Saharan Africa living with T2D or at risk to develop it.
