Characteristics of Registered Diabetics in Dhank Province in the Sultanate of Oman.

OBJECTIVE

The aim of this study was to estimate the prevalence of registered diabetics and describe the clinical and epidemiological characteristics of patients with type 2 diabetes mellitus (T2DM) in three primary health care centers in the Dhank province of Oman.

METHODS

This cross-sectional study included 567 individuals aged > 20 years old. Clinical data were obtained retrospectively from physical registers and electronic clinical records.

RESULTS

Of the total 567 patients with T2DM (age-stratified prevalence = 10.2%), 44.8% were men. The mean age of the patients was 55.8±15.6, and they had a mean body mass index (BMI) of 29.7±6.0. Diabetes duration was 5.9±4.0 years. Overall, 28.4% of the patients had glycated hemoglobin values < 7%. The percentages of patients who did not reach the recommended targets for high-density lipoprotein (HDL) (< 1.0 mmol/L), low-density lipoprotein (LDL) (> 2.59 mmol/L) and triglycerides (TG) (< 1.69 mmol/L) were 63.3%, 60.0%, and 34.6%, respectively. Almost half of all patients (43.40%) had a BMI > 30. Obesity and overweight were more prevalent in patients in the 30-59 age group compared to patients aged < 30 or > 60 years (p < 0.001). Almost all patients (93%) had an estimated Glomerular Filtration Rate (eGFR) of more than 60 mL/min/1.73m(2). The number of patients diagnosed with T2DM aged < 60 years has been increasing gradually from 2008 to 2015 compared to those > 60 years (p = 0.017). Patients were managed by lifestyle measures (14.2%), oral hypoglycemic agents (one or two; 50%), and insulin therapy (35.7%).

CONCLUSIONS

The prevalence of registered T2DM patients in Dhank is less than the national figure. This may be due to the location of Dhank as a border province. Further qualitative studies are recommended to elaborate on the factors that lead to poor glycemic control.
