Abstract:

Objective To discuss the influencing factors for the risk of Alzheimer’s disease (AD) after correction the Mini-Mental State Examination (MMSE) score trajectory, and to clarify the risk factors for of AD in the people with different MMSE scores. Methods The follow-up data from 2005-2016 were collected based on the AD Neuroimaging Program Database. After screening, the follow-up data of 425 people were finally included, and the variables were screened by LASSO method; the influencing factors of MMSE scores at different quantiles were analyzed by Bayesian quantile regression model, and COX model and Bayesian quantile regression joint model were used to analyze the main risk factors of AD. Results After screening, 10 variables were included, including albumin, total cholesterol, and blood glucose concentration and so on. The results of longitudinal sub-model analysis of the Bayesian quantile regression joint model showed that the influencing factors which affecting the change of MMSE score trajectory at different quartiles were the same, such as albumin, blood glucose concentration, age, gender,apolipoprotein E(APOE4) gene, race, and educational score. The Cox regression sub-model anslysis of the joint model results showed that race and APOE4 gene had the effects on the AD at all quartiles, and the risk ratios of APOE4 gene were 2.188((95%CI:1.775,2.620), 1.751(95%CI:1.422,2.042), 1.706(95%CI:1.391,2.102), and 2.056(95%CI:1.439,3.206).The total cholesterol level and history had the effects on the AD only at parts of quartiles. Conclusion The risk factors of AD are different in the people with different MMSE score distributions, and the degree of influencing are also different. Both APOE4 gene and whiteness are the risk factors of AD at different quartiles, and the total cholesterol level and history are the risk factors of AD only at parts of quartiles.
