RESUMEN
AIMS: This study aimed to evaluate changes in glycemic control and diabetes treatment by age group in Japanese patients with type 2 diabetes. METHODS: The study included the results of approximately 40,000 patients/year using cross-sectional and retrospective analyses from 2012 to 2019. RESULTS: There was little change in the glycemic control status in all age groups during the study period. However, by age group, patients aged ≤ 44 years continued to have the highest glycated hemoglobinA1c (HbA1c) values during the study period (7.4 % ± 1.7 % in 2012 and 7.4 % ± 1.5 % in 2019), especially in insulin-treated patients (8.3 % ± 1.9 % in 2012 and 8.4 % ± 1.8 % in 2019). Biguanides and dipeptidyl peptidase-4 inhibitors were widely prescribed. Sulfonylurea and insulin use showed a decreasing trend, but older patients had a higher percentage of prescriptions. Sodium glucose transporter 2 inhibitors were prescribed rapidly, especially in younger patients. CONCLUSIONS: There were no obvious changes in glycemic control over time in the study period. The mean HbA1c level was higher in younger patients, which suggested that improvement is required. In older patients, there was a trend toward greater emphasis on management to avoid hypoglycemia. Different treatment strategies based on age showed different drug choices.

AIMS/INTRODUCTION: Type 2 diabetes mellitus is caused by a relative imbalance between insulin secretion and sensitivity related to the body mass index (BMI). Seven categories of oral antidiabetic drugs (OADs) are available in Japan. It is important to assess the OAD utilization patterns based on patients' BMI levels. MATERIALS AND METHODS: OAD prescribing patterns from 2002 to 2019 were analyzed using the data collected in the computerized diabetes care database provided by the Japan Diabetes Clinical Data Management Study Group; OAD utilization patterns in 25,751 OAD-treated type 2 diabetes mellitus patients registered in 2019 were analyzed after classifying them into five categories of BMI. RESULTS: Comparing OAD usage between 2002 and 2019, sulfonylureas decreased from 44.5 to 23.2%, and biguanides (BGs) increased from 19.3 to 50.3%. Dipeptidyl peptidase-4 inhibitors (DPP4is) increased to 56.9% in 2019. Sodium-glucose cotransporter 2 inhibitors (SGLT2is) increased to 23.6% in 2019. About 90% of type 2 diabetes mellitus patients had BMI < 30 kg/m2 . DPP4is were the most used OADs in 2019. When BMI exceeded 30 kg/m2 , use of BGs and sodium-glucose cotransporter 2 inhibitors increased, and use of sulfonylureas and DPP4is decreased. Although DPP4is were the most used OADs for patients with BMI <30 kg/m2 , they were the third most prescribed OADs for patients with BMI >35 kg/m2 after BGs and sodium-glucose cotransporter 2 inhibitors . CONCLUSIONS: DPP4i usage was as high as that of BG in the analysis of Japanese type 2 diabetes mellitus patients with relatively low BMI. This was considered to be a treatment option appropriate for the pathophysiology in Japanese patients.
