| Objective To investigate and understand geriatric depression and emotion regulation strategy by a cross-sectional study in communities and nursing homes in Yinchuan, and explore its possible risk factors on different residential status, and the relationship between the geriatric depression and emotion regulation strategy, and provide reference basis for improving the depression in the elderly.Methods(1) A cross-sectional study of geriatric depression and emotion regulation strategy: the total of 1043 elderly peoples aged above 60 were selected. 538 elderly peoples from five communities were selected by convenience sampling and 505 elderly peoples from five nursing homes were selected by cluster sampling method in Yinchuan. Geriatric depression and emotion regulation strategy studied by cross-sectional study with GDS, ERQ and RRS.(2) 1:4 matching case-control study of the risk factors of geriatric depression: This study was based on a cross-sectional study, cases were selected moderately serve depression, which is the scores of GDS more than 20, and controls selected the scores of GDS less than 11 from cross-sectional study in nursing homes. This study included 47 cases and 188 controls which were matched age and sex in nursing homes. The data was collected using the self-designed questionnaire.Results(1) The results of cross-sectional study of geriatric depression and emotion regulation strategy as follows: the total incidence rate of the elderly depression was 32.0%, the incidence rate of the elderly depression was 35.5% in community and 28.3% in nursing homes, difference was significant( ?2=6.187, P < 0.05). The propensity score matching analysis confirmed that the relationship between residential status and depression was not significant in elderly people(?2=0.066, P > 0.798). Multivariate logistic regression analysis confirmed that older age, no spouse, low education level, no economy earning and no hobby were significantly risk factors of depression in community and younger age, no hobby and no family support were significantly risk factors of depression in nursing homes(P<0.05). The scores of cognitive reappraisal between male and female were significant difference(t =-3.406,P < 0.05); The scores of expressive suppression of low education level and no economy earning were significantly higher(t = 2.236,P < 0.05;t = 2.183,P < 0.05); The scores of rumination of the age from 60 to 70 was highest(F = 4.968, P < 0.05), the scores of no spouse was significantly higher than people who has spouse(t = 2.383,P < 0.05). The result of Pearson correlation found that the negative correlation of depression and cognitive reappraisal, expressive suppression were significant(r =-0.400,P < 0.01; r =-0.098, P < 0.05). The positively correlation of depression and rumination was significant(r = 0.652, P < 0.05).(2) The case-control study confirmed that after controlling for gender and age, multivariable conditional logistic regression analysis found that no hobby, the number of chronic diseases and negative life events were risk factors of depression. It was showed that people who has hobby affect geriatric depression by increasing risk for 0.254 times than people who has no hobby(95%CI: 0.097~0.662); the number of chronic diseases of the elderly every increase one then increasing risk of depression 2.18 times(95%CI: 1.456~3.264); People who has experience negative life events in past year affect depression by increasing risk for 25.825 times than people was not experience(95%CI: 7.323~87.310).Conclusion(1) The incidence rate of depression in the elderly was 32.0%, there was no significant difference in residential status.(2) The relationship between geriatric depression and emotion regulation strategy found that the correlation of depression and cognitive reappraisal was negative, the correlation of depression and rumination was positive.(3) No hobby, people who has more than one kind of diseases and people who experienced negative life events in past year were risk factors of depression in elderly people. |
