摘要
目的探讨抑郁情绪在居家不出与认知功能间的中介效应，为生命质量提高提供干预。方法采用便利抽样方法，对720名社区老年人应用精简版流调中心抑郁量表（CES—D—R）、中文版居家不出量表、简易精神状态检查表（MMES）进行调查分析并构建结构方程模型。结果社区老年人抑郁情绪得分为（3．95±4．12）分，居家不出状态得分（4．26±1．23）分，认知状况得分（21．52±4．04）分，认知障碍的发生率为37．1％。认知功能与居家不出状态、抑郁得分呈显著负相关（r=-0．409，P〈0．01；r=-0．485，P〈0．01），抑郁水平与居家不出呈显著正相关（r=0．555，P〈0．01）；社区老年人的年龄，性别，婚姻状况，文化程度，健康自评，住房面积，抑郁情况以及居家不出对认知功能有预测作用，可以解释认知功能50．8％的变异量（P〈0．05）；居家不出对认知功能有直接效应为-0．02（P〉0．05）；居家不出通过抑郁情绪对认知功能的间接效应为-0．45（P〈0．05）。结论老年人居家不出通过抑郁情绪对认知功能起中介效应。
Objective To investigate the intermediary effect of depression between housebound and cognition in community-dwelling older adults and to provide intervention for the improvement of the life quali- ty. Methods A total of 720 senior adults were selected to fill out demographic questionnaire,including Ra- sch-Derived Center for Epidemiological Studies Depression Scale （CES-D-R）, hoasebound scale and the minimcntal state examination （MMES）. Results The depression score of the elderly in community was （3.95±4.12） ,housebound score was （ 4.26± 1.23 ） , cognition score was （21.52±4.04） and the incidence rate of the cognitive disorder was 37.1%.Cognition was significantly negatively related to housebound and de- pression （r=-0.409, P〈0.01 ;r=-0.485,P〈0.01 ）.Housebound was significantly positively related to depres- sion （ r= 0.555, P〈0.01 ）. The community elderly age, sex, marital status, degree of education, self-assessment of health,living space, depression and the housebound could be used to predict the cognitive function, and all of them could explain the variance of cognitive function of 50.8% （P〈0.05） .Housebound had a direct effect of -0.02 on cognitive function （P〉0.05）. The indirect effect of housebound on cognitive function through de- pressive mood was -0.45（P〈0.05）. Conclusions The elderly housebound has an intermediary effect on the cognitive function through the depression.
