Eating performance is the functional ability to get food into the mouth and chew/swallow it. Nursing home residents with dementia commonly experience compromised eating performance and subsequent consequences. Prior work examined the association between resident eating performance and their cognitive and functional ability. Yet, the associations between resident eating performance and behavioral and psychological symptoms, psychotropic medication use, and comorbidities are less studied. This study aimed to examine the association between eating performance and cognition, functional ability, behavioral and psychological symptoms, psychotropic medication use, and comorbidities in nursing home residents with dementia.BACKGROUNDEating performance is the functional ability to get food into the mouth and chew/swallow it. Nursing home residents with dementia commonly experience compromised eating performance and subsequent consequences. Prior work examined the association between resident eating performance and their cognitive and functional ability. Yet, the associations between resident eating performance and behavioral and psychological symptoms, psychotropic medication use, and comorbidities are less studied. This study aimed to examine the association between eating performance and cognition, functional ability, behavioral and psychological symptoms, psychotropic medication use, and comorbidities in nursing home residents with dementia.This was a secondary analysis using baseline data from two randomized controlled trials, testing the impact of Function Focused Care on function and behavioral symptoms in 882 residents with moderate-to-severe dementia (mean age 86.55 years, 71% female, 30% non-white, 68.5% severe dementia) from 67 nursing homes in two states between 2014 and 2020. Eating performance (dependent variable) was measured using the single self-feeding item of Barthel Index. Independent variables included cognitive impairment, functional ability (Barthel Index total score excluding the self-feeding item score), behavioral and psychological symptoms (agitation, depression, resistiveness-to-care), psychotropic medication use (anti-depression, sedative, anti-psychotics, anti-seizure, anti-anxiety), and comorbidities.METHODSThis was a secondary analysis using baseline data from two randomized controlled trials, testing the impact of Function Focused Care on function and behavioral symptoms in 882 residents with moderate-to-severe dementia (mean age 86.55 years, 71% female, 30% non-white, 68.5% severe dementia) from 67 nursing homes in two states between 2014 and 2020.

On average, residents had five documented comorbidities (SD = 3.06, range = 0-12) and were on approximately one psychotropic medication (SD = 1.25, range = 0-5). Eating performance was associated with cognitive impairment (OR = 0.53, 95% CI = 0.35, 0.79, p = .002), functional ability (OR = 1.05, 95% CI = 1.04, 1.06, p < .001), depressive symptoms (OR = 0.94, 95% CI = 0.89, 0.98, p = .007), and anxiolytic use (OR = 0.64, 95% CI = 0.42, 0.99, p = .046).RESULTSNearly 39% of residents were dependent in eating.

Targeted interventions to accommodate to cognitive function, optimize functional ability, minimize anxiolytic use, and manage depressive symptoms are encouraged to support eating performance in residents with dementia.CONCLUSIONSFindings supported that better eating performance was associated with less cognitive impairment, higher functional ability, fewer depressive symptoms, and less anxiolytic use. Targeted interventions to accommodate to cognitive function, optimize functional ability, minimize anxiolytic use, and manage depressive symptoms are encouraged to support eating performance in residents with dementia.
