Unexplained weight loss seen in people with dementia can lead to further complications, including mental and physical deterioration according to new research from Bournemouth University.
Results among participants in local Dorset care homes showed that there were significant variations in calorie and fluid intake over the course of a day. Daily food intake ranged from 700 – 3,000 calories per day, with some people not eating enough to fulfil their daily living tasks.
The Body Mass Index of participants also showed huge variation, with 40% being classified as underweight. Fluid intake fluctuated between 372 ml and 2,025 ml per day, with some people not meeting their recommended daily fluid intake of 1,500ml per day.
The use of a light weight physical activity monitor – Sensewear Armband from Body Media – provided an innovative way to objectively determine total energy expenditure, sleep duration and physical activity.
The results showed that physical activity and sleep patterns varied hugely with people spending between 6 and 23.7 hours undertaking sedentary activity. This suggested that poor sleep patterns and lack of physical activity may be contributing to low food intake.
Lead researcher, Dr. Jane Murphy, said: “People may need much longer to eat due to poor coordination or becoming tired more easily, while others may be losing their appetites or face difficulties with chewing and swallowing. As dementia progresses, many people become less able to sense their thirst, meaning that they may be unaware they are dehydrated.
“Care staff are facing increasingly complex demands and we hope that the training resources we are developing as a result of our research will provide the tools needed to support good nutrition for people with dementia.”
