Abstract:
Objective To investigate the reciprocal relationships between trajectories of depressive symptoms(DS)and cognitive function(CF)and to provide a basis for formulating comprehensive management for depression and cognitive impairment among older adults.Methods Group－based dual trajectory modelling was performed to identify dual trajectories of DS and CF usinglongitudinal data from the Chinese Health and Retirement Longitudinal Study.Results 3076 older adults were included in the analysis.Four trajectories of DS(DS1~DS4)were determined:constantly low(30.7%),mild increasing lightly(46.7%),moderately decreasing(19.0%),and constantly high(3.6%);four trajectories of CF(CF1~CF4):persistently high(8.3%),suboptimal slowly decline(51.8%),middle rapidly decline(33.8%)and low rapidly decline(6.1%).Compared with DS 1,the elderly in DS 2~4 were more likely to experience CF 3 and CF 4.Using CF 1 as a reference,the elderly in CF 2~4 were more likely to follow DS 2~4.Conclusion GBMDT captures the degree of overlap and dynamic developmental associations between developmental trajectories for DS and CF among Chinese elderly.
