Diabetes treatment has evolved over the last decade. During this time, the IDMPS, a global observational survey on the management and patterns of care of people with type 1 and type 2 (T2D) diabetes in the developing world, has collected data in 7 individual waves. Each wave enrolled different participants. We report the glycemic condition and the frequency of diabetes-related cardiovascular complications in participants with T2D observed between 20and 2017 in 48 countries across Africa, the Middle East, South Asia, Latin America, Asia, and Eurasia.
From Wave 1 to Wave 7, no improvement in the proportion of people achieving HbA1c <7% was seen. This is the case for all groups, i.e., those receiving oral glucose-lowering drugs (OGLDs) plus injectable treatments, and those receiving insulin (Table). The proportions of participants with micro- and macrovascular complications appear relatively unchanged. Throughout all waves, the proportion of participants receiving insulin remained constant (≈20%). For those treated with OGLDs plus basal insulin, the median daily dose of insulin was 0.21 U/kg in 20and 0.32 U/kg in 2017; over the same period, the median BMI at diagnosis increased from 26 kg/m2 to 29 kg/m2. This lack of progress highlights the continued need for improvements in diabetes management and education.
