Prevalence and Risk Factors for Dementia among Senile Outpatients in Nanchong Central Hospital

Objective To identify the prevalence and relative risk factors for dementia among gerontic outpatients. Methods Six hundred and forty-four outpatients aged 60 years old or older were evaluated in Nanchong Central Hospital during July 2007 to May 2009. Mini-mental state examination （MMSE） was used for screen dementia patients. In addition, information such as education status, smoking, co morbidities and the use of medication were collected. Results The prevalence of dementia was 16.0%. The variables related closely with dementia were age, histo ry of stroke, arterial hypertension, hearing impairment and sight impairment. Conclusion Advanced age, arterial hypertension, and vascular brain injury are the main risk factors associated with dementia, which suggests that public health measures adopted to prevent and control modifiable risk factors can mitigate the prevalence of dementia.
