Summary

The purpose of this study is to investigate the one-year trajectory of changes in depression status in older adults with mild cognitive impairment and subthreshold depression, and to explore relevant risk factors for predicting changes in depression status. This one-year prospective longitudinal follow-up study involved 400 (expected) subjects who met the diagnostic criteria for mild cognitive impairment combined with subthreshold depression in older adults, and their depressive status was assessed using the Geriatric Depression Scale (GDS). Follow up monitoring of depression status at 6 and 12 months. Obtain factors related to changes in depressive status (such as age, gender, education level, cognitive function, anxiety level, sleep status, social support, psychological resilience, social network, etc.). By studying the longitudinal trajectory of depression status in elderly patients with mild cognitive impairment and subthreshold depression, a multi state Markov model with time and state discreteness is constructed, namely: State 1 (normal); State 2 (subthreshold depression); State 3 (mild depression); State 4 (moderate depression); State 5 (severe depression). Deeply explore and analyze the impact of certain factors and indicators on the transition between states, and estimate the probability of transition between states.
