Abstract
The well-being of caregivers of persons with dementia (PWD) is often overlooked and caregivers have an increased risk of malnutrition. Poor functional status as measured by handgrip strength is an indicator of malnutrition. Protein intake plays a role in preventing muscle wasting and maintaining muscle mass and function. This secondary data analysis aims to provide insight into whether dietary protein intake is associated with higher handgrip strength and lower risk of malnutrition among caregivers of PWD. Participants were obtained from the ADMIRE study, a cross-sectional study of 50 dyads of PWD and their caregivers (52-88 y). Dietary intake was assessed using the Diet History Questionnaire III (DHQ III) in which energy, total protein, animal protein, and vegetable protein were derived. Other outcomes included handgrip strength z-score (HGS) and nutrition status (Mini Nutrition Assessment). Associations were examined using Pearson R. There were no associations between HGS and total protein, animal protein, or vegetable protein. There was a significant association between nutrition status and HGS among females (r=.398, p<0.05). Two of 47 participants met sarcopenic levels for HGS. Most participants had adequate functional status by handgrip standards. More research is needed to establish a clear relationship between protein intake and HGS and malnutrition risk among caregivers of PWD.
