Factors associated with glycaemic control among patients with type 2 diabetes mellitus in Ho, Ghana: A cross-sectional study

Background

The purpose of this study was to assess the status of glycaemic control and associated factors among patients with type 2 diabetes mellitus patients.

Methods

This was a hospital-based cross-sectional descriptive study of 326 patients with type 2 diabetes at the Ho Municipal and Teaching Hospitals. The adequate sample size was calculated using Yamane formula N/1 + Ne², with 95 % confidence interval, 5 % margin of error and 10 % non-response rate and a sample size of 326 was determined. Using the sampling frame of patients chart, systematic random sampling technique was used to select the study participants. Glycaemic level was assessed using fasting blood glucose (FBG) readings. A poor glycaemic control was when an average of three months blood glucose level was above 130 mg/dl (7 mm/L). Data was analysed using STATA version 15.0.

Results

Out of 310 patients who participated in the study, more than two-thirds (76.1 %) had poor glycaemic control. Patients who use combination of oral medication and insulin (AOR = 3.67, 95 % CI: 1.34–8.74), patients with diabetes for 16 years or more (AOR = 4.67, 95 % CI: 2.44–9.29), patients who did not practised diabetes self-care activities (AOR = 4.32, 95 % CI: 2.82–9.31) and patients with complications were (AOR = 2.47, 95%CI: 1.45–8.66) more likely to have poor glycaemic control. Age, employment, diabetes education, comorbidities, diabetes self-care activities, treatment type, complications, resident and duration of diabetes were significantly associated with poor glycaemic control.

Conclusion

Based on this findings, teaching and counselling provided by nurses, physicians, dietitians and pharmacists should focus on improving adherence to diabetes self-care activities to attain good glycaemic control.
