Abstract
Post-stroke depression (PSD), a prevalent complication of stroke, causes poor outcomes. However, little is known about its prevalence and management among community-dwelling stroke survivors. Thus, we investigated the prevalence, awareness, and treatment of PSD in a community setting. A cross-sectional study was performed using representative data from the Korea National Health and Nutrition Surveys 2014, 2016, and 2018. A total of 11,122 participants aged ≥ 40 years were categorized, including 343 stroke survivors and 10,779 non-stroke survivors. We then calculated and compared the prevalence, awareness (formal diagnosis of depression by a doctor), and treatment rates of depression between the two groups. Depression was defined as a score ≥ 10 in the nine-item Patient Health Questionnaire (PHQ-9). Depression was significantly more prevalent among stroke survivors than in non-stroke survivors (22.2% vs. 8.5%, respectively), while the differences in the awareness and treatment rates were insignificant. However, only 46.8% of stroke survivors with PSD were aware of their condition, and only 20.5% were receiving treatment. These results suggest that clinicians should more actively screen for and treat depression among stroke survivors.

Post-stroke depression (PSD), a prevalent complication of stroke, causes poor outcomes
Various studies have reported that the presence of post-stroke depression (PSD) negatively affected the clinical outcomes of stroke s urvivors[4]
Several previous studies have investigated the prevalence of PSD, these mainly were focused on the development of depression among hospital-based patients shortly after the stroke onset rather than the overall depression status of stroke survivors in a community setting[5,15]
Summary
Post-stroke depression (PSD), a prevalent complication of stroke, causes poor outcomes. Only 46.8% of stroke survivors with PSD were aware of their condition, and only 20.5% were receiving treatment These results suggest that clinicians should more actively screen for and treat depression among stroke survivors. Several previous studies have investigated the prevalence of PSD, these mainly were focused on the development of depression among hospital-based patients shortly after the stroke onset rather than the overall depression status of stroke survivors in a community setting[5,15]. Few studies have examined the awareness and treatment rates of depression among stroke survivors, leading to little knowledge about these, especially in Korea. This study aimed to assess the prevalence, awareness, and treatment of depression among community-dwelling stroke survivors using nationwide representative cross-sectional data from the Korea National Health and Nutrition Survey (KNHANES) to offer constructive perspectives in the screening and management of depression among stroke survivors
