Multiple factor analysis of depression in community-dwelling elderly residents in Beijing :A cross-sectional study / 中华老年医学杂志

ABSTRACT

Objective To investigate the mental states of the community-dwelling elderly in Beijing ,and to explore their relationship with depression using multivariate analysis ,in order to provide evidence for strategies to prevent depression in the elderly. Methods A total of 400 community elderly residents in Chaoyang District of Beijing were recruited in this cross-sectional study. The mental states of older adults were assessed by using the Zung Self-Rating Depression Scale(SDS) ,the Medical Outcomes Study(Mos)36-item Short Form Health Survey (SF-36) ,and the Social Support Rating Scale(SSRS).The correlations of the mental state with demographic data ,quality of life and social support were examined via multivariate analysis. Results Of 400 questionnaires ,364 were valid.Depression occurred in 64 older adults ,and the detection rate was 17.6% (64/364).Multivariate linear regression analysis showed that depression was closely correlated with age ( P = 0.049 ) , physiological function(P=0.009) ,vitality(P=0.028) ,mental health(P＜0.001) ,self-reported health transition(P=0.003) ,objective support(P=0.001)and subjective support(P=0.001)in community-dwelling elderly residents in Beijing.Bivariate Logistic regression analysis showed that five factors , including vitality (OR = 0.595 ,P= 0.036 ) ,mental health (OR = 0.548 ,P = 0.021 ) ,self-reported health transition(OR=1.597 ,P= 0.048) ,objective support (OR= 0.524 ,P= 0.018)and subjective support(OR=1.787 ,P=0.027) ,were influencing factors for depression in the elderly.Self-reported health transition and subjective support had the greatest impact on depression in the elderly . Conclusions Critical approaches to preventing depression in the elderly include a focus on the mental health and social needs as well as measures to enhance self-confidence in the health of these individuals.
