Glucose control in Rwandan youth with type 1 diabetes following establishment of systematic, HbA1c based, care and education

Abstract

AimsTo assess change in glycemic control concurrent with increased clinic visits, HbA1c testing, and education. Rates of complications were also examined. MethodsA 1–2 year follow-up of 214 members of the Rwanda Life for a Child program (aged <26 years) with a first HbA1c between June 2009 and November 2010 was conducted. Data were analyzed for the entire cohort and by age (<18 years, ≥18 years). Trajectory analysis was performed to identify trends in HbA1c. ResultsMean overall HbA1c decreased significantly from baseline (11.2±2.7%; 99±30mmol/mol) to one- (10.2±2.6%; 88±28mmol/mol) and two- (9.8±26%; 84±25mmol/mol) year follow up visits. The prevalence of microalbuminuria did not significantly change (21.0%, 18.8%, and 19.6%), nor did nephropathy (4.7%, 7.8%, and 5.4%). However, rates of hypertension (31.8%, 44.9%, and 40.3%) were higher than expected. Five HbA1c groups were identified by trajectory analysis, and those with the worst control monitored their glucose significantly fewer times per week. ConclusionsThe establishment of regular care, HbA1c testing, and increased education is associated with significant improvements in glycemic control in youth with type 1 diabetes (T1D) in sub-Saharan Africa, but the high prevalence of hypertension is of concern.
