Depression among patients with type 2 diabetes mellitus: Evidence from the Northeast region of Vietnam.

Abstract Background and aims Herein, we aim to examine the prevalence of depression in type 2 diabetic patients at a provincial general hospital located in the Northeast region of Vietnam and to explore its relationship with some sociodemographic, lifestyle and medical history characteristics. Materials and methods This was a single-centre cross-sectional descriptive study. The patients of both sexes who were at the age of 18 years or above, were treated at our institution and were diagnosed with type 2 diabetes mellitus, previously or during the study period. A total of 220 patients were included in the study. Results Depression prevalence was 32.27% according to ICD–10. The severity of depression was categorized as mild in 77.46% patients, moderate in 19.72% patients and severe in 2.82% patients. The odds of depression was 0.18 (95%CI 0.05–0.69, p = 0.012) less for those known as the upper social class compared with those in lower social class. Those who were not on insulin treatment had significantly higher odds of depression than those on treatment with insulin (OR 2.06, 95%CI: 1.01–4.21). Individuals on treatment without oral diabetes drugs had higher odd of depression compared to those being treated with oral diabetes drugs (OR 2.77, 95%CI: 1.14–6.73). Also, hypertension was an increasing contributor to the depression prevalence (OR 2.32, 95%CI: 1.10–4.90). Conclusions A high prevalence of depression among type 2 diabetic patients was documented. Only significant factors for depression were lower social class, co‐morbid hypertension and none of the insulin treatment or oral diabetes drugs.
