【Abstract】 Objective: To understand the prevalence of senile dementia in the people aged 65 and older of Tianshui,and explore the risk factors of senile dementia. Methods: Using the multistage stratified cluster sampling method,1873 subjects aged 65 or older were identified in Tianshui city. These subjects were screened with the Hasegawa dementia scale( HDS) and the expanded version of the general health questionnaire( GHQ) and classified as high,moderate or low risk dementia groups. Different proportions of the three groups were assessed with the Hachinski ischemic score( HIS),the clinical dementia rating( CDR) and the fourth edition of the diagnostic and structured clinical interview for DSM-IV-TR axis I disorders( SCID-I / P). Results: Totally 1859 subjects completed the survey. The prevalence of senile dementia was 13. 66%( 95% CI = 10. 38 %-17. 98%). The prevalence of senile dementia was higher in males( 16. 20%) than in females( 11. 09%),and higher in rural residents( 12. 91%) than in urban residents( 9. 09%); however,the differences were not significant( P>0. 05). The prevalence of senile dementia increased with the age( P<0. 01),wherein 7. 44 of those aged 65-70,17. 48% of those aged 71-75,20. 08% of those aged 76-80,21. 22% of those aged 81-85,and 30. 23 of those aged 86 and older. Advanced age,low family income,bad marriage,living alone and low education level were the risk factors of senile dementia.
