Prevelence of depression in Iranian women with breast cancer: a systematic review and meta-analysis.

Introduction: Depression is a debilitating disease that is highly prevalent among cancer patients. Various studies in Iran have reported different prevalence. This systematic review and meta-analysis was conducted to estimate the overall prevalence of depression in Iranian women with breast cancer.

Material And Methods: In this study, published articles in Persian and English were collected without time limit. Keyword searches for depression, depressive disorder, dysthymic disorder, major depressive disorder, breast cancer, breast neoplasm, and Iran and all of their potential combinations were performed in Scientific Information Database (SID), MagIran, PubMed, Scopus, Web of Science databases. The heterogeneity between studies was assessed using the Q-Cochrane test and, given the significant heterogeneity, a random-effects model was used to estimate the overall prevalence of depression. Data were analyzed using STATA version 11 software.

Results: The analysis of 22 selected articles with a total sample size of 3,082 showed that the overall prevalence of depression in women with breast cancer was 49.98% (95% confidence interval: 48.43-52.52). The prevalence of depression in Region 1 in the country was (28%; 95% confidence interval: 25.53-52.55) and in other regions, it was (63.79% with 95% confidence interval of 61.82-76.76). The highest and the lowest prevalence of depression were related to BDI (69.33%; 95% confidence interval: 67.19-71.48) and HADS (26.43%; 95% confidence interval: 23.14-29.72), respectively.

Conclusions: Half of the Iranian women with breast cancer had depression. Given the overlap of physical symptoms of cancer with depression, identifying at-risk patients for controlling and providing therapeutic interventions seems necessary.
