رابطه کیفیت خواب با افسردگی در افراد سالمند در سه ناحیه شهر تهران

Objectives: Most old age people are facing physical and mental problems such as movement problems,&nbsp;chronic pain, sleeping problems, seclusion, and depression. Thus, it is necessary to allocate a good share&nbsp;of health and treatment resources in any society to old age people and attend their problems. This study&nbsp;aimed to examine the relationship between sleep quality and the level of depression in people residing&nbsp;in nursing homes of 3 districts of Tehran City, Iran, in 2013. Methods & Materials: This descriptive-analytical study included people living in nursing homes of Tehran&nbsp;Welfare Organization. The study sample consisted of 90 older people who were selected through cluster&nbsp;random sampling considering the proportion of the northern, central, and southern regions of Tehran and&nbsp;observing their level of consciousness, ability to respond, and willingness to participate in the study. To&nbsp;obtain the data, we used 2 questionnaires of Pittsburgh sleep quality index and geriatric depression scale.&nbsp;Then, the obtained data were analyzed through multivariate regression. Results: Older women constituted 60% of the participants. The findings revealed that there was a negative&nbsp;and significant relationship (P<0.001) between sleep quality of the elderly people and their depression&nbsp;level. However, there was a positive and significant relationship (P<0.001) between the level of&nbsp;depression and variables of sleep disorders, using sleep aids, and disorders in daily activities. Conclusion: There is a causal and mutual relationship between sleep disturbances and depression, in such&nbsp;a way that sleeplessness could end in depression, and if the depression signs are ignored, it will gradually&nbsp;affect sleep quality. Generally, sleep disturbances are mutually associated with depressive mood and low&nbsp;quality of life. Therefore, to enhance sleep quality and decrease the level of depression in people residing&nbsp;in nursing homes, the necessity of special care programs in the old age should be emphasized. With&nbsp;regard to limitations of this study, we cannot generalize our results to all old population as our study was&nbsp;confined to only 3 districts of Tehran. In addition, since some variables like education and economic status&nbsp;of old age people were not considered in this study, there is a need to generalize the findings. Finally,&nbsp;it is recommended that future studies should investigate the relationship between sleep quality, lifestyle,&nbsp;and daily activities in the nursing homes.
