Abstract：Objective:To explore the correlation between cognitive reserve and subjective cognitive decline.Methods:A total of 300 elderly people aged≥60 in communities and hospitals in Hebei were selected by convenient sampling,and they were investigated by general data questionnaire,self-assessment form of subjective cognitive decline(SCD)and cognitive reserve parameter collection table.Results:Among the 300 elderly people,185(61.67%)had subjective cognitive decline.Multiple analysis showed that experienced negative life events in the past two years was a risk factor for SCD in the elderly,and participation in cognitive activities was a protective factor for SCD in the elderly.Cognitive reserve was correlated with cognitive decline(OR=0.984,P<0.05).Among the three sub-variables of cognitive reserve,length of full-time education,main occupation and cognitive activity,cognitive activity was correlated with SCD(OR= 0.869,P<0.05).Conclusion:Experience negative life events is a risk factor for the elderly to have SCD.Participating in cognitive activities has a protective effect on SCD for the elderly.cognitive reserve has an independent protective effect on SCD for the elderly.Improving cognitive reserve for the elderly may delay the SCD process.
