Objective To explore the factors affecting cognitive function in the community elderly and the rela-tionship between cognitive function and symptoms of depression and anxiety.Methods The cognitive function,de-pressive symptoms and anxiety symptoms of 3387 elderly in Haidian District of Beijing were investigated by using Ascer-tain Dementia 8-item Questionnaire(AD8),Geriatric Depression Scale 15(GDS-15)and Self-rating Anxiety Scale(SAS).Multivariate logistic regression was used to examine the correlation between cognitive function and depression and anxiety symptoms.Results The positive rates of cognition impairment,depression and anxiety were 23.71%,16.92%and 10.84%,respectively,and 6.61%of the subjects also had symptoms of depression and anxiety.Mul-tivariate logistic regression analysis showed that age group ≥ 85 years old and age group 75-84 years old,female,the source of income is provided by their children,self-rated hearing loss and poor self-rated health were risk factors for cognitive decline.Compared with the elderly without depression and anxiety symptoms,only depression symptoms(OR=4.596,95%CI:3.802~5.556),anxiety symptoms(OR=3.800,95%CI:3.041~4.749),depression and anxiety symptoms co-existed(OR=4.721,95%CI:3.578~6.230)was associated with a higher risk of cognitive im-pairment,and remained statistically significant after adjusting for demographic,socioeconomic,and health behavior factors(P<0.001).Conclusion Depression,anxiety or both symptoms are higher risks of cognitive decline,and are the key groups for the prevention of cognitive impairment.
