Introduction
Cases of type 2 diabetes mellitus (T2DM) are increasing worldwide, and projections are that the numbers will continue to rise. However, if measures or programs for prevention are established and implemented, the incidence rate may go down. The scoping review was conducted to identify the knowledge gap in T2DM prevention programs and thus support the research the authors were conducting, to develop a lifestyle modification program for the prevention of T2DM in a Sub- Saharan Africa (SSA) country. The findings may also be used by policy makers and other researchers.
Objective
The objective of this scoping review was to map and synthesize the available evidence on lifestyle modification programs for prevention of type 2 diabetes mellitus in Sub-Saharan Africa.
Methods
The Joanna Briggs Institute Scoping Review Methodology was used to guide the review process. An electronic search was conducted for articles published between January 2006 and March 2024. English articles that reported T2DM prevention programs using lifestyle modification in SSA were included. Rayyan software (2016) was used to store the selected literature.
Results
A total of nineteen (19) articles were included in the review. Some articles included were from the years 2019 and 2020 (n = 4, 21.1 %). Most of them were descriptive narrative reviews (n = 10, 52.6 %). Two programs for the prevention of T2DM which were on trial were identified and articles that focused on lifestyle modification were included. The most common setting was the desktop (n = 12, 63.2 %) then communities (n = 5, 26.3 %) and health facilities (n = 2, 10.5 %).
Conclusion
There is need for country and culture specific T2DM prevention programs and trials need to be done to ensure this is achieved. The need for more research was evidenced by few articles that mapped program characteristics, outcomes and gaps in SSA. Awareness campaigns should include adults and young children. There is also need for large scale trial programs to test adaptability of already established programs from other countries.
