Objectives: The aim of this study is to find out the effect of ApoE genotype on correlation between head circumference and cognition of the elderly in the community.
Methods: A total of 1,152 subjects (380 men and 772 women) aged 60-91 years were analyzed from preliminary data of GDEMCIS (Gwangju Dementia and MCI Study). The study questionnaire consisted of demographic characteristics, current and past illness history, drug history and K-MMSE (Korean version-Mini Mental State Examination). We also measured the head circumference and examined ApoE genotype.
Results: On regression analysis, as head circumference becomes smaller, K-MMSE scores decreased adjusted by age, sex, educational level, ApoE epsilon4 allele, current smoking and alcohol drinking status (beta=0.15, p=0.04). Only in the lowest quartile group, presence of ApoE epsilon4 allele reduced K-MMSE scores adjusted by age, sex, educational level, height, current alcohol drinking and smoking status (beta=-1.39, p=0.008).
Conclusion: These results suggest that head circumference may have an influence on K-MMSE scores, and presence of ApoE epsilon4 allele may be a medicating factor.
