Prevalence and Predictors of Depression in Diabetic Patients - An Institution Based Screening in West Bengal

Background: Depression is a highly prevalent and common cause of disabilities among the diabetic population. The presence of depression affects self-management behaviors and glycemic control leading to an increase morbidity and mortality rate but remains undiagnosed in many cases. Aims: This study aims to assess the prevalence and predictors of depression in diabetic patients at a selected tertiary health care centre, Kolkata, West Bengal. Methods: A cross-sectional survey was carried out with 290 diabetic patients attending endocrinological OPD in July - September 2021 at selected Govt. Hospital, Kolkata. Depression was screened through Patient Health Questionnaire (PHQ9). The sociodemographic and clinical characteristics of the participants were assessed through validated semi-structured interview schedule. Binary logistic regression was computed to assess the predictors of depression. Statistical significance was detected at p < 0.05. Result: Total 290 adult diabetic patients were screened for depression. The prevalence of depression was 56.9% (mild – 56.83%, moderate – 26.43% and severe – 16.74%). Marital status (AOR: 2.243, 95% CI=1.063, 4.734), family support (AOR: 2.073, 95% CI=1.257, 3.419) and poor glycemic control, PPBS level > 180 mg/dl (AOR: 1.665, 95% CI=1.018 – 2.722) were proved as the independent predictors of depression in this study population Conclusion: Depression was present in more than half of the diabetic patients. Early detection of depression and family involvement would be helpful in glycemic control and better outcome. Key words: Prevalence, Predictors, Depression, Diabetes mellitus.
