Elderly people prone to malnutrition

Washington, Sept. 6: Malnutrition in elderly people is quite common. While malnutrition can occur at any age, elderly people aged 65 and above are particularly prone to it. The latest study tries to explore the reason behind the same.

Malnutrition is a condition where people have a drastically reduced dietary intake and the body lacks energy and nutrients as a result.

According to Prof. Dr Dorothee Volkert, one of the researchers, the consequences of malnutrition are manifold.

They range from weight loss to a weakened immune system or functional impairment of muscles and all organs. The body falls back on all its reserves.

A team of researchers, led by Volkert, set out to explore which of a total of 23 variables — ranging from aspects such as difficulties with chewing and swallowing or cognitive impairments to loneliness and depression or moving into a care home — were decisive for malnutrition.

“The research partners took six existing sets of data from studies on the elderly over the age of 65 and re- evaluated them using a common approach. We then compiled the results in a m e t a - a n a l y s i s , ” explains Prof. Dr Volkert.

The result suggested that malnutrition in the elderly appears to be caused by a surprisingly narrow range of factors. Age, marital status, difficulties with walking had a significant role to play.

The average age of the 4,844 participants in the six studies on which the results are based was between 72 and 85. All those surveyed lived in private homes in Germany, Ireland, the Netherlands, and New Zealand. Between 4.6 and 17.2 per cent of the participants developed malnutrition over the course of the studies.

“The older the people are, the more likely it is that they will suffer from malnutrition” Dr Dorothee Volkert concluded.

The findings appeared in the Journal of the American Geriatrics Society. — ANI
