Purpose: To determine the associations between apolipoprotein E (APOE ) genotypes and serum levels of glucose, total cholesterol, and triglycerides in a cognitively normal aging Han Chinese population.
Methods: There were 1,003 cognitively normal aging subjects included in this study. APOE  genotypes were analyzed and biochemical parameters were tested. All the subjects were divided into three groups according to APOE  genotypes: (1) E2/2 or E2/3 (APOE  E2); (2) E3/3 (APOE  E3); and (3) E2/4, E3/4, or E4/4 (APOE  E4). Correlations of serum levels of glucose, total cholesterol, and triglycerides with APOE  genotypes were assessed.
Results: E2, E3, and E4 allele frequencies were found to be 6.2%, 82.1%, and 11.7%, respectively. Serum levels of total cholesterol were higher in the APOE  E4 group (<0.05). A higher level of total cholesterol was associated with the E4 allele (adjusted odds ratio 1.689, 95% confidence interval 1.223–2.334,<0.01). However, no association was found between APOE  status and serum levels of glucose (adjusted odds ratio 0.981, 95% confidence interval 0.720–1.336, =0.903) or total triglycerides (adjusted odds ratio 1.042, 95% confidence interval 0.759–1.429, =0.800).
Conclusion: A higher serum level of total cholesterol was significantly correlated with APOE  E4 status in a cognitively normal, nondiabetic aging population. However, there was no correlation between APOE  genotypes and serum levels of glucose or total triglycerides.
