| Objective The aim of this study was to introduce the multi—slate Markov modelfor the prediction of mild cognitive impairment(MCI)to AIzheimer’S diseaselAD)and to find out the related factors for AD preventionan dearly in tervention among tile elderly.Methods MCI.moderate to severe cognitive impairment.and AD were defined as state 1.2 and 3,respectively.A three—state homogeneous model with discrete states and discrete times from data six follow—up visits was constructed to explore factors for various progressive stages from MCI to AD.Transition probability and survival curve were madeafter the model fit as sessment.Results At the level of 0.05,data from the multivariate analysis showed that gender(HR=1.23,95％c,：1.12一1.38).age(HR=l.37,95％G／:L071~72), hypertension (HR=1.54,95％C/：1.3一2. 19) were statistically significant for the transition from state I to state 2. while age(HR=O.78,95％C1：0.69—0.98).education level(HR=1.35. 95％Cl：1.09一lr86)and reading(HR=1.20,95％c,：1.01一1.41)were：statistically significant for transition from state 2 to state l,and gander(HR=1.59,95％C／：1.33一1.89), age(HR=1.33,95％C／：1.02-1.64), hypertension(HR=1.22,95％C／：1.1l一1.43).diabetes(HR=1.52,95％CI：1.12—2. 00),ApoEe4(HR=1.44. 95％CI：1.09—1.68)were statistically significant for transition from statc 2 to slate 3.Based 0n the fired modeI,the three-yeart ransition probabilities during each state at average covariate Ievel were estimated.Conclusion To delay the disease progression of MCI.phase by phase prevention measures could be adopted based On the main factors of each stage.Multi-state Markov model could imitate the naturalhistory of disease and showed great advantage in dynamically evaluating the development of chronic diseases with multi-states and multi-factors. |
