[Prevalence and factors associated with depression among institutionalized elderly individuals: nursing care support]

The objective of this study was to verify depression among institutionalized elderly individuals. The cross-section method and Yesavage's Geriatric Depression Scale were utilized in five geriatric long-term care facilities located in the Federal District to verify symptoms of depression. A total of 299 individuals were studied, 181 of whom did not meet the inclusion criteria. Sixteen individuals declined to participate. Considering the 102 individuals found suitable to participate in the study, 49.0% presented symptoms of depression; 36.3% suffered from mild to moderate depression and 12.7% showed symptoms of severe depression. Associations were found between depression symptoms and increased age, female gender, physical limitations/dependence and dissatisfaction with the institution. A significant association was also found between depression and insomnia, tachycardia, paresthesias, dizziness and excessive sweating. Depression is highly prevalent among institutionalized elderly individuals, more common among women, and correlated with a series of signs and symptoms that may help in making an early diagnosis, thus offering support to providing more effective nursing care.
