Prevalence of and factors associated with poststroke depression: a Malaysian study

This study investigated the prevalence of depression 3-6 months poststroke and examined specific factors associated with depression in a stroke population of the University Malaya Medical Centre, Kuala Lumpur, Malaysia. It was hypothesised that poststroke depression (PSD) is prevalent in the poststroke population of University Hospital Malaysia and that PSD is significantly correlated with demographics, educational background, medical history, rehabilitation attendance, traditional medicine use, prestroke and poststroke activities, religiousness, activities of daily living, and social support. The study group comprised 80 patients admitted to the hospital with stroke of any etiology. Mean patient age was 56.8 years (standard deviation +/- 12.5 years). The results were derived by comparing the 80 stroke patients with 80 controls matched for age, sex, race, and medication use. Results were also derived from comparisons between depressed and nondepressed members of the stroke population (n = 80). The diagnosis of depression was based on the Zung Self-Rating Scale and confirmed by a psychiatrist, based on DSM-IV criteria. Interviews were conducted based on a 26-item questionnaire, modified Barthel Index, and Social Resources Scale were used to assess which factors correlated with depression. Depression was found to be common among Malaysians 3-6 months after stroke. A total of 66% of the patients were depressed, with depression considered mild in 51% and moderate to severe in 15%. It was demonstrated that the occurrence of depression was significantly correlated with age, ethnicity, noncontinuance of prestroke lifestyles, and poor performance in the activities of daily living rating.
