Factors associated with glycemic control in type 2 diabetic patients in Saudi Arabia

To identify factors associated with glycemic control in type 2 diabetes mellitus patients in tertiary academic hospital.

This was a retrospective cross-sectional study of adults with type 2 diabetes mellitus. Data were extracted from the electronic health record (EHR) database for the period from 1st of January to 31st of December 2016. Participants were considered to have a glucose control if the HbA1c level was less than 7% [53 mmol/L]. Descriptive analysis and multivariable logistic regression model were performed to assess the factors associated with glycemic control.

A total of 728 patients were included in the study for which (65%) were female, and about 60% of the sample size was between 45 and 60 years old. Multivariate logistic regression model showed participants older than the age of 65 were less likely to have controlled diabetes compared to the younger participants (OR: 0.53 [CI: 0.30-0.93]). Moreover, those who had hypertension (OR: 0.61 [CI: 0.43-0.86]) and dyslipidemia (OR: 0.53 [CI: 0.38-0.74]) were less likely to have controlled diabetes, while those with asthma (OR: 2.06 [CI: 1.16-3.68]) were more likely to have controlled diabetes. The model also showed that vitamin D deficiency was not associated with glycemic control in type 2 diabetes patients (OR 0.80 [95% CI 0.58-1.12]).

These findings highlighted the need for appropriate management in older adult patients to prevent the complication of type 2 diabetes. Furthermore, attention should be exercised for patients with factors associated with poor glycemic control such as hypertension and dyslipidemia.
