[Depression, cognitive deficit and factors associated with malnutrition in elderly people with cancer].

The study sought to analyze the presence of depression, cognitive function, nutritional status and factors associated with malnutrition in the elderly undergoing treatment for cancer. A cross-sectional study was conducted in a cancer clinic in Minas Gerais, which included the application of a sociodemographic and health questionnaire, assessment of depressive symptoms, cognitive function and nutritional status. 96 elderly people were evaluated, 50% of which were female and the mean age was 70.6 years. Cognitive impairment was identified in 39.6% and the presence of depression in 17.7%, with a higher number of depressive symptoms in females (p = 0,017). Moderate malnutrition or suspected malnutrition was diagnosed in 29.2%, severe malnutrition in 14.6% and 47.9% had a critical need for nutritional intervention. In multivariate analysis, functional impairment was independently associated with malnutrition (PR: 3.40; CI: 1.23-9.45), the presence of two or more symptoms of nutritional impact (PR: 3.22; CI: 10.03-10.10) and current treatment by chemotherapy (PR: 2.96; CI: 1.16-7.56). The elderly with cancer showed a high prevalence of malnutrition and a need for nutritional intervention. The assessment of depression and cognitive impairment should also be an integral part in addressing this group.
