Prevention of type 2 diabetes in sub-Saharan Africa,a review

Abstract

Background:

Type 2 diabetes (T2D) is a significant factor in the overall burden of non-communicable diseases (NCDs) in sub-Saharan Africa (SSA). While many health organizations call for increased attention to this disease, far fewer resources are being allocated to evidence-based prevention programs. The literature demonstrates a lack of reporting on prevention programs, interventions targeted to decrease the development of T2D, and success stories.

Methods:

This review followed the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Databases searched were PubMed, Google Scholar, Ovid, Medline, World Health Organization (WHO) Library Information System, and African Journals Online. The following terms were searched individually and in multiple combinations: prevention, intervention, type 2 diabetes, sub-Saharan Africa, education, strategy, strategic plan, risk factors. In total, 253 articles were found and 17 were removed as duplicates. Of these, 78 abstracts were reviewed, with 20 being excluded for not meeting criteria, one was excluded as it was not available in English and one was excluded for lack of availability. After the remaining 56 full-text studies were assessed, seven were included in the review.

Results:

Throughout the review, the common theme between articles was a lack of resources, lack of prevention strategies, and increasing risk factors. The review highlights the fact that while there are WHO guidelines and packages targeted at primary care level interventions for the prevention and treatment of NCDs, they remain underutilized. Included studies looked at the knowledge level of family members, social marketing and sugar consumption, and primary prevention strategies.

Conclusion:

There is an overall lack of reporting on interventions targeting the prevention of type 2 diabetes in SSA. Further research is warranted on interventions, prevention strategies, and implementation of the WHO package targeted at NCDs
