Relativity study on sleep disturbance and anxiety, depression for elderly inpatients

Objective To investigate the correlation between sleep disturbance and anxiety,depression in elderly inpatients. Methods A total of 200 elderly inpatients were selected from Navy General Hospital from October 2005 to October 2009. Pittsburgh sleep quality index(PSQI)was used to assess the sleep quality,and those with Pittsburgh sleep quality index more than 8 were considered having sleep disturbance. The 200 patients were divided into the group of PSQI more than 8(n=147)and the group of PSQI less than 8(n=53). The total was assessed using the Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS)and compared with national norm. Results Incidence of depression and anxiety(44.21%,54.42%)in the group of PSQI more than 8 were higher than those in the group of PSQI less than 8(11.32%,18.86%),the differences were significant(P0.05). The anxious and depressive symptoms in the two groups of patients were both higher than those in the national norm,the differences were statistically significant(P0.01). Conclusions The elder inpatients without sleep disturbance had higher incidence of anxious and the depressive symptoms. The poorer the sleep quality in elder inpatients had the higher rate of anxiety and depression.
