Depression and Diabetes Distress in South Asian Adults Living in Low- and Middle-Income Countries: A Scoping Review.

OBJECTIVES: In this study, we conducted a scoping review to identify the prevalence of both depression and diabetes distress in patients with type 2 diabetes in low- and middle-income countries in South Asia. METHODS: This scoping review was grounded in the methodology of Arksey and O'Malley by searching for relevant studies using Ovid MEDLINE, PsycINFO and Cumulative Index of Nursing and Allied Health Literature databases, as well as grey literature sources and hand searches. Two reviewers independently screened and extracted data from articles that met the inclusion criteria. RESULTS: A total of 46 studies were included, with only 1 addressing both depression and diabetes distress. We present 42 total articles on depression and 5 on diabetes distress. The prevalence of type 2 diabetes and elevated depressive symptoms ranged from 11.6% to 67.5%, whereas the prevalence of diabetes distress ranged from 18.0% to 76.2%. CONCLUSIONS: The prevalence of elevated depressive symptoms was found to be much higher than that reported in data from high-income countries and in data on South Asians living in high-income countries. Diabetes distress was found to be lower compared with other studies; however, the scarcity of data makes this observation inconclusive. Variations in depression inventories, lack of culturally tailored inventories and the focus on urban clinic-based populations are identified as limitations and areas requiring further research. Our review provides evidence for the need of increased mental health screening and treatment in diabetes care in South Asian countries.
