Mild to Severe Depressive Symptoms in Elderly Stroke Survivors and Its Associated Factors: Evidence From a Cross-Sectional Study in Zhejiang Province, China

Abstract

Objective: The objective of the study is to explore the prevalence of mild to severe depressive symptoms in elderly stroke survivors and its associated factors. Methods: We did data analyses of 335 elders with stroke history. Data were collected in a survey conducted between 2014 and 2015, among permanent residents aged 60 and older in Zhejiang Province, China. Prevalence of mild to severe depressive symptoms among stroke survivors were calculated, and univariate analyses and multilevel logistic regression were used to explore its associated factors. Results: Prevalence of mild to severe depressive symptoms was 22.09% (95% CI: 17.65-26.53%) in elders with stroke history, more than twice compared to their counterparts not suffering stroke (9.77%, P < 0.001). In multilevel logistic regression, we found that elderly stroke survivors who were illiterate (OR = 2.33, p = 0.008), or had limitation in activities of daily living (OR = 3.04, p = 0.001) were more likely to be present with mild to severe depressive symptoms, respectively, while those with more fresh vegetable consumption were at lower odds (OR = 0.82, p = 0.047). Conclusions: Prevalence of mild to severe depressive symptoms was high in elderly stroke survivors. Targeted screening might be needed for those being illiterate, disabled in activities of daily living, and having little consumption of fresh vegetable. The association between fresh vegetable consumption and depressive symptom in stroke patients calls for further research.
