Depression in Urban Omani Adults with Type 2 Diabetes: A cross-sectional study

This study aimed to identify the prevalence of clinically significant depression among adult Omani patients with type 2 diabetes mellitus (T2DM) and explore potential associations with sociodemographic and clinical variables in this population.

This descriptive cross-sectional study was conducted between August 2018 and September 2019 and included 427 Omani T2DM patients from 12 randomly selected government health centres in Muscat, Oman. An Arabic version of the validated Patient Health Questionnaire-9 was administered to the participants via face-to-face interviews to determine the prevalence of depression.

A total of 111 T2DM patients (response rate: 100%) had depression (26%). The presence of a personal history of depression was the only variable significantly associated with depression (P <0.001). Other sociodemographic and clinical factors including age, gender, duration of diabetes, glycated haemoglobin level, mode of diabetes treatment or the presence of diabetes-related complications such as cardiac complications, renal impairment, retinopathy, neuropathy and erectile dysfunction, were not associated with depression, (P >0.050 each).

This study revealed a high prevalence of depression among urban Omani adults with T2DM and a personal history of depression, which was found to be significantly associated with depression. Therefore, early screening for depressive symptoms is necessary to improve the quality of life of diabetic patients in this region.
