Structural Model for Estimating the Influence of Healthy Lifestyle on Episodic Memory in Adults with Subjective Memory Complaints

The aim of this study is to examine the relationships between a healthy lifestyle and episodic memory among adults with subjective memory complaints (SMCs). We proposed a structure equation model to study the association between a healthy lifestyle and episodic memory with an investigation covering 309 participants over 50 years old with SMCs. The model showed a good fit after being adjusted (p=0.054, goodness of fit index=0.981, adjusted goodness of fit index=0.956, comparative fit index=0.981, and root mean square error of approximation=0.049): a healthy lifestyle has a direct positive effect on episodic memory among adults with SMCs (β=0.60). The research model provides possible guidelines for medical staff to prevent the cognitive function decline in the risk population of Alzheimer's disease.
