Undiagnosed depression among adults with diabetes mellitus in Jos.

BACKGROUND

Diabetes mellitus (DM) and depression are common chronic disease states of public health importance with huge burden and the potential to impact many aspects of life. They are said to be related though this relationship is not fully understood. The presence of depression among patients with DM is associated with poor glycemic control, complications, and poor self-care.

METHOD

This was a descriptive cross-sectional study conducted at the Diabetes Clinic of the Jos University Teaching Hospital. Three hundred and ten (310) patients with diabetes mellitus were recruited consecutively. The depression module of the Mini International Neuropsychiatric Interview (M.I.N.I.) version 5.0 was used to ascertain depression among these patients. Other demographic data were obtained using a questionnaire. Blood pressure, weight, and height were also measured and the body mass index (BMI) calculated.

RESULTS

One hundred and eighty four (59.35%) of the study population were females and the mean age (SD) of the study population was 54 ± 12 years. The mean age (SD) of the females was 53 ± 11 years and that of the males was 54 ± 12 years with no significant statistical difference (P = 0.35). Two hundred and forty nine (80.32%) of the study population were urban dwellers with 140 (45.16%) earning less than N500, 000 (794 USD) yearly. Current major depression was found in 35 (11.3%) patients, among whom 7 (2.3%) had recurrent depression. The presence of DM complications (OR: 3.50, 95% CI 1.16-10.61) and a positive family history of depression (OR: 4.03, 95% CI 1.32-12.29) were found to be correlates of current major depression.

CONCLUSION

The prevalence of current major depression among patients with diabetes mellitus in this study is high. We recommend that all patients with DM should be screened for depression and treated appropriately to reduce its consequences.
