Multivariate unconditional logistic regression analysis was used to analyze the related factors of swallowing dysfunction. Results:The incidence of swallowing dysfunction was 26.04% （132 out of 507）. Univariate analysis showed that there were significant differences in the incidence of swallowing dysfunction among the elderly in terms of age， spouse condition， self-care ability， health status， taking sleeping pills， cerebrovascular disease， nervous system disease and depression （P<0.05）.
