Resumo: |
Aging promotes physical and functional changes commonly associated with the decline in nutritional status. However, as they develops together with these organic changes and are also associated with the course of many diseases that affect the elderly, changes in nutritional status are not properly diagnosed. Knowing that the decline in nutritional status is related to vulnerability increases in the elderly, their detection could serve as an early indicator for negative outcomes in this population. In this context, this thesis presents three original articles. The first article, entitled MALNUTRITION RISK AND HOSPITALIZATION IN ELDERLY ASSISTED IN PRIMARY CARE investigates the association of malnutrition risk and single items of the Mini Nutritional Assessment (MNA®) with hospitalization in the elderly in southern region of Brazil. In this cross-sectional study, which evaluated 1229 elderly persons, the frequency of malnutrition and risk of malnutrition was two times greater among the elderly who were hospitalized in the 12 months prior to the investigation. There was a significant association between hospitalization and 11 of the 17 items on the MNA® evaluated. Of these, seven items were independently associated with hospitalization. The second article, EVOLUTION OF NUTRITIONAL STATUS AND HOSPITALIZATION OF ELDERLY ASSISTED IN PRIMARY CARE, evaluated a subsample of the first, in a longitudinal study of three years with 375 older persons from the city of Cruz Alta - RS, to analyze the association between hospitalization, evolution of nutritional status, and socioeconomic, demographic, lifestyle, health, and nutritional factors. The results showed a worsening of nutritional status in 10.7% of elderly in the period, which was independently associated with hospitalization. In the third article, NUTRITIONAL STATUS AND DEATH OF ELDERLY ASSISTED IN PRIMARY CARE: AN 3-YEAR FOLLOW-UP STUDY, the role of nutritional status as a predictor of death among the elderly assisted in Primary Care in the city of Cruz Alta, RS, in a three-year follow-up period were investigated. Additionally, the association of the MNA® items with the incidence of death and the impact of the nutritional status on the survival of the elderly were analyzed. A total of 450 elderly persons were evaluated, of which 75 deaths were recorded in the period (16.7%). Malnutrition was the main predictor of death in the sample, regardless of sex, age group, home arrangement, health self-perception, number of cardiometabolic diseases and history of neoplasias. In addition, undernourished and at risk of malnutrition elderly exhibited lower cumulative survival. Items of the MNA® predictors of death were impaired mobility, body mass index <23 kg/m2 and eating dependence. The association between nutritional status and occurrence of hospital admission and death provides evidence that nutritional status is an important health indicator and should be monitored by a specific tool for the elderly and easy to use in public health, such as MNA®. |
