The Ganepão conference considers, within its educational proposal, the dissemination of knowledge as a fundamental action. On this space, you can follow relevant nutrition contents based on scientific evidence.
In the Ganepão 60 nutrisegundos of this month, we shared the results of the recently published study in the Nature, which evaluated the prognostic value for mortality of the new ESPEN criteria for malnutrition in 437 elderly people.

Study performed by Swedish researchers aimed at assessing the mortality predictive value for malnutrition and cause-death influence in the elderly.
The survey included 1767 subjects aged ≥ 65 years admitted to hospital within a year. The nutritional status was assessed by the Mini Nutritional Assessment (MNA) and 20 causes of death were classified according to the International Statistical Classification of Diseases and Related Health Problems.
The authors identified 1% of the elderly with risk of malnutrition and 9.4% malnourished, 839 participants (47.5%) died with a median follow-up of 5.1 years. The mortality predictive model identified significant associations (HR = hazard ratio) between malnutrition and risk of malnutrition, respectively, and death due to neoplasms (HR = 2.43 and 1.32); mental and behavioral diseases (HR = 5, 73 and 5, 44); diseases of the nervous system (HR = 4.39 and 2. 08), diseases of the circulatory system (HR = 1.95 and 1.57) or respiratory diseases (HR = 2.19 and 1.49).
Malnutrition and risk of malnutrition are associated with increased mortality regardless of the cause of death, which emphasises the need for nutritional screening to identify older adults who may require nutritional support.
