Dementia, nutrition, and self-feeding: a systematic review of the literature

SUMMARY The outcomes of feeding training are typically evaluated in terms of feeding skills and swallowing abilities rather than the ultimate goal of feeding, namely, adequate nutritional status. To increase occupational therapy practitioners' awareness of nutritional status as an outcome of feeding training, a systematic review of the research literature was conducted to examine the relationship between nutritional status and self-feeding skills in people with dementia. Studies were evaluated by the strength of their evidence and analyzed to determine the relationships among dementia, nutritional status, and the ability to feed one's self. Results revealed that although nutritional status in people with dementia is variable, there is a tendency for lower body weight, lower measures of body composition, and lower body mass indexes in persons with dementia compared to those with no cognitive impairment. Individuals who feed themselves tend to weigh more compared to those who need assistance for feeding. There is also evidence to support that as feeding status improves or declines, body weight similarly increases or decreases.
