This study was done to compare demographic characteristics, comorbidity, and health habits of elders with mild cognitive impairment (MCI) and elders with cognitively normal function (CNF).

Secondary data analysis was conducted using data from the Database of the Seoul Dementia Management Project for 5,773 adults age 60 and above.

The MCI group showed an older age distribution, but there was no significant education difference between the two groups. Elders with MCI had more diabetes and stroke than elders with CNF. In subgroups, the same findings were observed in women, but not in men. While more men with MCI had hypertension compared to men with CNF, there was no significant difference in hypertension between the two groups for women. Elders with MCI, men in particular, had a lower prevalence of obesity than men with CNF. MCI individuals did less exercise compared to individuals with CNF. While there were no significant differences in alcohol consumption and smoking between MCI and CNF groups, the over 80's subgroup with MCI reported more alcohol consumption.

Findings from this study could be helpful in designing community-based dementia prevention programs and health policies to reduce the prevalence of dementia or related cognitive impairments.

The aim of this study was to clarify the actual condition of elders with dementia who were registered in the Seoul Dementia Management Project.

Data were collected from 5,312 elderly patients with dementia. Demographic included characteristics, comorbidity, and healthy lifestyle habits; data from the Seoul Dementia Management Project.

First, demographic characteristics were as follows; mean age at the time of definite diagnosis was 78.0 yr. There were slightly more women (69.3%), and 4.55 yr was the average length of education with 41.4% being illiterate or uneducated patients. Second, there were several comorbidities including hypertension (61.7%), diabetes mellitus (31.8%), hypercholesterolemia (10.2%), heart disease (11.1%), obesity (4.2%), and stroke (21.4%). Third, alcoholic history was found in 11.8% of the patients, and smoking in 9.8%. Regular exercise was done by only 29.1% of the patients with dementia. Finally, significant differences between men and women were found for the following; age, education, medical security, hypertension, diabetes mellitus, stroke, alcoholic consumption, smoking, and regular exercise.

Authors expect that the present data will be used for establishment of dementia associated projects and policies.
