Screening for depression in diabetes in an Indian primary care setting: Is depression related to perceived quality of life?

Abstract

AimsTo screen for depression in diabetes and evaluate the contributing factors in a primary care setting in India. To evaluate the relationship of depression with perceived quality of life. MethodsWe used convenience sampling method in this cross-sectional study. 388 consecutive patients with type 2 diabetes mellitus were enrolled over a period of one year. 50.3% patients screened positive on Patient Health Questionnaire (PHQ-9) out of which 21.4% reported moderate to severe depression. Male gender, middle age and poor glycaemic control were associated with depression. In stepwise linear regression analysis when depression category was included as an independent variable, significant difference in regression equations were found. Other independent variables which were included in regression equation were age, education, gender, income lifestyle, glycosylated haemoglobin and Body Mass Index whereas dependent variables were transformed domains of World Health Organization Quality of Life questionnaire. ResultsThere is high prevalence of depression in primary care in type 2 diabetes patients in this Indian setting. Depression was strongly associated with all four domains of quality of life. Highest association with depression was seen in Physical domain (β −0.385, p = 0.000) followed by Social domain (β −0.372, p = 0.000). ConclusionsHigh prevalence of depression and its association with poor quality of life indicates need for improved recognition of depression for improving diabetes outcomes in this centre.
