ABSTRACT
Background: Hyperphagia, a common eating behavioral change in patients with dementia, is one of the risk factors for institutional placement. No study of hyperphagia has yet been conducted on institutionalized patients with dementia. There is currently no academic consensus over the correlations among hyperphagic behaviors, agitated behaviors, cognitive function, and demographic characteristics in this patient group.
Purpose: This study explores the prevalence and predictors of hyperphagic behaviors in institutionalized patients with dementia.
Methods: A cross-sectional and correlational design was used. The participants were recruited from seven dementia special care units and assisted living facilities in Taiwan. One hundred seventy-nine patients with dementia agreed to participate. Two research assistants were trained to collect data using the subscale for hyperphagic behaviors, the Cohen-Mansfield Agitation Inventory, the Cognitive Abilities Screening Instrument, and a dementia patient demographic characteristics datasheet.
Results: The prevalence of hyperphagic behaviors in institutionalized patients with dementia was 50.8% (91/179). After excluding the variables from the long-term memory, short-term memory, attention, abstraction and judgment, and verbally nonaggressive behavior subscales scores, we found gender, length of institutionalization, category fluency, and physically nonaggressive behavior subscale scores to be significant predictors of hyperphagic behaviors (p < .05).
Conclusions/Implications for Practice: Findings suggest that institutionalized male patients with dementia with longer institutionalization who have either a relatively low-fluency task score or a relatively high frequency of physically nonaggressive behaviors are at greater risk for exhibiting hyperphagic behaviors. Once hyperphagic behaviors are found in a patient, a transdisciplinary case meeting should be held to develop an appropriate dietary management plan, and further identification and treatment should be done by a neurologist or a psychiatrist.
