Fingerfoods: a clustered-randomized feasibility study to enhance fruit and vegetable consumption in Dutch patients with dementia in a nursing home
Abstract Background Eating problems are highly prevalent in older patients with dementia and as a consequence, patients are at greater risk of becoming malnourished. Fingerfoods, snacks that can be picked with thumb and forefinger, could be used to counteract malnutrition in patients with dementia. The aim of this feasibility study was to evaluate whether providing fingerfoods as snacks was feasible for both patients with dementia and caregivers. Secondary objectives were to explore the effects of fingerfoods on total fruit and vegetable consumption, nutritional status and quality of life. MethodsInstitutionalised patients with dementia ( N = 22, 86% female, mean age = 85 years) were included in this clustered randomized controlled feasibility trial in the Netherlands. The intervention group ( N = 15) received their regular diet supplemented with fingerfoods, comprising quiches and cakes rich in fruit or vegetables, for 6 weeks. The control group ( N = 7) received their regular diet. Daily fingerfood consumption of patients and attitude of caregivers towards the fingerfoods were recorded to measure feasibility of the intervention. Fruit and vegetable consumption (3-day food records), nutritional status (body mass index (BMI) and SNAQ rc scores) and quality of life (QoL) (QUALIDEM) were measured in the first and last intervention week. The effects of fingerfoods on these outcomes were analysed with paired t-tests, Chi-square tests and ANCOVA. Results Patients consumed on average 70 grams of fingerfoods daily, containing 41 grams of fruit/vegetables. The intervention was rated as positive by 58% of the caregivers. Changes in fruit and vegetable consumption, malnutrition risk and QoL scores during the study period did not significantly change in the intervention group compared to the control group. Conclusion This feasibility study showed that providing fingerfoods to patients with dementia seems feasible for both patients and caregivers and could provide a pragmatic approach to enhance fruit and vegetable consumption in institutionalized elderly. In future research, long-term effects of fingerfoods should be studied on larger scale to confirm these findings. Trial Registration: Requested.
