Abstract
Objective
To explore the associations of depressive symptoms with functional status and frailty in elderly outpatients.
Methods
A total of 297 geriatric outpatients(aged 65 years and over)from Zhejiang Hospital were recruited in the cross-sectional study from January 2014 to December 2015.We gathered general information, and evaluated depressive symptoms by Geriatric Depression Scale-15(GDS-15), cognitive function by mini-mental state examination(MMSE), frailty by clinical frailty scale(CFS), activities of daily living(ADL)by Barthel index, instrumental activities of daily living(IADL), balance, POMA and gait by Tinetti-performance oriented mobility assessment(Tinetti-POMA), grip strength and 4m gait speed by 4-meter walk gait speed test.According to the GDS-15 scores, 297 geriatric outpatients were divided into a depression symptom group(n=35, GDS-15≥6)and a non-depressive symptom group(n=262, GDS-15<6). The frailty and functional status were compared between two groups by SPSS 23.0.
Results
As compared with non-depressive symptoms, the depressive symptoms group had higher clinical frailty scale(CFS), lower body mass index(BMI), lower cognitive function and poorer grip strength and balance(all P<0.05). There were significantly negative correlations of Geriatric Depression Scale-15(GDS-15)with ADL, IADL, gait, balance, POMA and grip strength(r=-0.165、-0.154、-0.216、-0.291、-0.305、-0.314, All P<0.05), while there were significantly positive correlations with CFS score, gait speed(r=0.256、0.198, both P<0.05). The more severe the frailty was, the higher the risk of depressive symptoms was(OR=3.650, 95% CI 1.611-8.271).
Conclusions
The cognitive and physical functions in the elderly with depression symptoms are poorer as compared with the elderly without depression symptoms.Elderly outpatients with more severe frailty have a higher risk for depressive symptoms.
