Abstract:

Objective To explore the cross-lagged effect between cognitive function and depression in the elderly in communities.Methods Based on the longitudinal study,the cross-lagged panel model was used to analyze the cognitive function and depression performance of elderly people in 2013 and 2017. The cross-lagged effect was analyzed by the structural equation model.Results ①The results of ANOVA showed that the cognitive function and the depressive behavior have a decreasing trend with time,and the decline level of women is more severe;②The correlation analysis showed that the baseline cognitive function score was positively correlated with the follow-up cognitive function score（r=0.632,P<0.001）;the baseline depression score was positively correlated with the follow-up depression score（r=0.485,P<0.001）;the follow-up cognitive function score was negatively correlated with the follow-up depression score（r=-0.166,P=0.002）;the baseline cognitive function score did not have correlation with the baseline and follow-up depression scores（P>0.05）;③The results of cross-lagged regression analysis showed that the cognition at baseline positively predicted cognition at follow-up（ β=0.718,P<0.001） and depressive symptoms at follow-up（ β=-0.133,P=0.004）;the depressive symptoms at baseline positively predicted those at follow-up（ β=0.518,P<0.001）.But there was no significant predicted effect between cognition at baseline and depressive symptoms at baseline（ β=-0.155,P=0.006）.Conclusion The baseline cognitive function level of the elderly in the community have a predictive effect on the follow-up of depression,while the baseline depression level have no predictive effect on the follow-up of cognitive function,and the relationship between the cognition and depression should be further explored.
