Associated factors of poor glycemic control in Iranian diabetic patients

According to the world health organization the prevalence of type 2 diabetes in our country and world will increase sharply by 2030. Because improving glycemic control delays the onset and progression of diabetes complications, recognizing related factors is key step in the effective treatment of these patients. Therefore, this study was performed to determine the predictors of poor glycemic control.

This study was a cross sectional study performed on 388 diabetic patients referring to the diabetes clinic in year 2019 (Semnan, Iran). The mean glycosylated hemoglobin was used as glycemic control index, and Hb A1C >7% was considered as poor glycemic control. Exclusion criteria were pregnancy, use of corticosteroid or cytotoxic drugs, malignancy, hemoglobinopathy, anemia, uremia, secondary diabetes, history of GI bleeding, surgery and blood transfusion in the last 3 month. All patients with type 2 diabetes who did not meet the exclusion criteria were included in the study.

The mean Hb A1C was 8.044 ± 1.46 and 74 % of the patients had poor glycemic control. 44.5% of the patients had BMI> 30 kg/m² and 89.9 % of them had abdominal obesity. There was an association between poor glycemic control and gender, type of treatment and duration of diabetes. Women, individuals treated with injectable insulin, and patients with the duration of diabetes less than 5 year had better control.

Our study showed that duration of diabetes and type of treatment are independently associated factors of glycemic control.
