Resumo: |
Malnutrition is one of the most important and common condition among the elderly that negatively affects health and quality of life. With ageing, the loss of weight is an expected physiological process. However, in the presence of dementia, the weight loss is involuntary and the risk of malnutrition becomes imminent. The risk of malnutrition may be present even before clinical diagnosis of mental illness. Some studies suggest that an alteration in the nutritional status might appear as a predictor of severity and progression of cognitive decline. The present study aimed to investigate the independent association of malnutrition risk with depressive symptoms, memory deficit or dementia in older adults. This is a cross-sectional population-based study that 176 participants aged 60 years and older were evaluated for nutritional risk, depressive symptoms, cognitive function. Data was collected from structured interviews and assessments in the participants homes and in the hospital for trained staff. The Mini Nutritional Assessment (MNA®) was used to assess the risk of malnutrition. Depressive symptoms were screened using the short version of Geriatric Depression Scale (GDS-15). For the cognitive assessment a board of certified neurologists, psychiatrists and neuropsychologists used validated tests combined with golden standard clinical criteria. Cognitive assessment was taken using the Mini-Mental State Examination (MMSE), word list memory and constructional praxis from the standard neuropsychological battery of Consortium to Establish a Registry for Alzheimer s Disease (CERAD), and Wechsler verbal and logical memory test. The functional status was evaluated using the Katz Index and Pfeffer Scale. The clinical diagnosis of dementia was based on the recommendations from the National Institute on Aging-Alzheimer s Association workgroups on diagnostic guidelines for Alzheimer s disease. The results showed that means variations of malnutrition risk were significantly different (P<.001) comparing elderly considered normal (26.9±2.8) with those with depressive symptoms (25.0±3.5), memory deficit (25.5±3.8), memory deficit plus depressive symptoms (24.0±3.3) and dementia (21.9±5.9). A multivariate analysis model with a robust estimation of Prevalence Ratios (PR) using the Poisson regression demonstrated that dementia (PR:14.006, P<.001), memory deficit plus depressive symptoms (PR:5.759, P=.003), depressive symptoms (PR:5.350, P=.014); memory deficit (PR:3.338, P=.046), and 70-79 years age group (PR:0.457, P=.031) were independent factors associated with malnutrition risk. These results were controlled for gender, marital status, educational level and income. In conclusion, the most important finding was the independent relationship with memory deficit and malnutrition risk. These results suggest that nutritional disturbances may start earlier than previously expected by others studies. None study detected malnutrition risk combining objective measurements of precocious memory impairment with careful observance of depressive symptoms in a robust controlled analysis. |
