Abstract

Institutionalized older adults are at greater risk of malnutrition, which is associated with cognitive impairment. This study investigated the association between nutritional status, advanced activities of daily living (AADL), and cognitive function among Brazilian older adults living in care homes. This cross-sectional study was conducted on 95 older adults (73.3 ± 12.5 years). Socio-demographic variables, cognitive function (measured by Mini Mental State Examination - MMSE), AADL, Mini Nutritional Assessment (MNA), and anthropometric variables were assessed. Regarding MNA, 37.8% were malnourished, 47.3% were at risk of malnutrition, and 14.9% were well-nourished. Malnourished participants (37.8%) and those with fewer number of AADL (82.3%) showed cognitive decline (MMSE < 24) (p = 0.000 and 0.030, respectively). Inadequate waist-hip ratio was associated with cognitive decline (OR 9.3; 95% IC, 9.06 - 9.85; p = 0.03). Nutritional status and AADL were associated with cognitive function. Nutritional assessment helps to early identify malnutrition and possibly to prevent cognitive impairment.
