    Abstract

    Purpose

    Confronting the growing burden of dementia requires understanding the causes and predictors of dementia in order to develop preventive strategies. In Korea a large proportion (71%) of dementia is Alzheimer's disease, and the risk factors have not yet been elucidated. Dietary factors may be possible risk factors, however research on the relationship between Alzheimer's disease and dietary behaviors has been insufficient. The purpose of this study was to investigate the association between compliance with the "Dietary Guidelines for Elderly (The Ministry of Health and Welfare, 2011)" and Alzheimer's disease among Korean elderly.

    Methods

    Elderly persons who visited a University hospital or a dementia center of Seoul and agreed to participate in the examinations were selected. Among 277 subjects, 89 Alzheimer patients were selected with diagnosis and 118 subjects were assigned to the control group. Diagnosis of Alzheimer's disease was based on Alzheimer's disease criteria of Diagnostic and Statistical manual of Mental Disorders, 4th edition (DSM-IV) and criteria of National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and related Disorders Association (NINCDS-ADRDA). Information on the general characteristics, health related behaviors and compliance with the dietary guidelines for Korean elderly was collected by face to face interview using a structured questionnaire. Anthropometric variables were measured during the survey.

    Results

    Total compliance score of dietary guidelines was significantly lower in the Alzheimer's disease group than in the control group (p = 0.0001). The odds ratio of Alzheimer's disease was significantly decreased in the group with the highest dietary guideline compliance score (OR = 0.47, 95 % CI = 0.18~1.09) compared to the group with the lowest compliance score.

    Conclusion

    The results indicate that increasing compliance with the dietary guidelines could be an effective strategy to decrease the risk of Alzheimer's disease among Korean elderly.
