Abstract

Background: Seasonal variation of HbA1c has been in focus.
Patients and Methods: The protocol included type 2 diabetes (T2D) patients (n=26, 71.4±10.2 years) on vildagliptin and metformin (EquMet) and HbA1c changes in 4 seasons for 6 years.
Results: HbA1c values ranged 6.9-7.5%, and tend to show highest in winter, and rather lower in autumn.
Discussion & Conclusion: Rather elderly T2D cases can tolerate EquMet with fair control. Previous reports showed a similar tendency. Some factors may be involved in the variation, such as temperature, climate, carbohydrate intake, Ramadan, and others. Furthermore, blood pressure and cardiovascular disease (CVD) can also influence them.
