Structured diabetes self-management education and glycaemic control in low- and middle-income countries: A systematic review

Aim To determine the association between structured diabetes self-management education (DSME) and glycaemic control in persons living with diabetes (PLD) in low- and middle-income countries (LMICs). Methods PubMed, Embase and Cochrane databases were searched up to June 2020 for intervention studies on the effect of structured DSME on glycaemic control in PLD in LMICs (PROSPERO registration CRD42020164857). The primary outcome was reduction in glycated haemoglobin. Included studies were assessed for risk of bias (RoB) with the Cochrane RoB tool for randomised trials. Findings were summarized in a narrative synthesis. Results Out of 154 abstracts retrieved and screened for eligibility, nine studies with a total of 1389 participants were included in the review. The structured DSME interventions were culturally tailored and were delivered in-person. They were associated with reductions in glycated haemoglobin in all studies: mean/median reduction ranged between 0.5% and 2.6% relative to baseline. Conclusions There is a dearth of literature on the association between structured DSME and glycaemic control among PLD in LMICs. The evidence available suggests that in LMICs; particularly in sub-Saharan Africa, structured DSME is associated with reduction in glycated haemoglobin. We recommend further intervention studies on the effects of structured DSME in LMICs.

Automated summary

There is a lack of research on the association between structured diabetes self-management education (DSME) and glycemic control in low- and middle-income countries (LMICs). However, existing evidence suggests that structured DSME is associated with reductions in glycated hemoglobin in these countries, particularly in sub-Saharan Africa.
