The current study aimed to evaluate the prevalence and associated factors of abuse among the elderly in Kashan, Iran. Materials and methods: This cross sectional study was conducted on 500 people over 60 years old in Kashan, Iran in 2014. Subjects were randomly selected from 10 healthcare centers of Kashan. Data were collected using elder abuse questionnaire. Cronbach alpha coefficient of the questionnaire was determined as 0.975. Data were analyzed by SPSS version 13. Pearson correlation coefficient and logistic regression analysis were used for data analysis. The statistically significant level was P<0.05. Results: Results of the current study showed that 80% of subjects have experienced at least one type of abuse during the last year. The highest rate of abuse was in the form of financial abuse (45.6%), and the lowest was in ostracizing (16.6%). There was a statistical significant relationship between the elder abuse and variables such as sex, age, number of children, marital status, living arrangement, residential situation, home properties, monthly income, insurance situation, illness history, walking ability and using mobility aids. Logistic regression analysis also showed significant relationship between the elder abuse and unemployment, living in an apartment, and the age range 71-80 years.
