Asking About an Older Person’s Appetite Can Be a Lifesaver

A simple question about appetite can provide insights into older people’s general health that may help reduce their risk of dying, according to a study published in September 2014 in the journal Appetite. Emeritus Professor Mark Wahlqvist from Monash University’s Department of Epidemiology and Preventive Medicine and the Monash Asia Institute led a team investigating the connection between appetite and mortality.

A release from the university quotes Professor Wahlqvist as saying, “Appetite is generally regarded as one of the most important indicators of health. ” He explains that the urge to eat is often reduced in the elderly, with many afflicted by “anorexia of aging”. Chewing difficulties, general deterioration or the side effects of medication may have an adverse effect on appetite, as may psychological factors such as loneliness or depression. Family circumstances and other environmental factors may also play a role.

“Factors of this kind lead to poor appetite and related poor health,” Professor Wahlqvist said. “We found that elderly people with fair or poor appetites had higher risks of mortality than those with good appetites.”

The study, based on data from more than 1800 independently living Taiwanese over the age of 65, found that those who had poor appetites consumed a less diverse diet than others, with a consequently lower intake of energy, protein, vitamins and other nutrients.

It also showed appetite to be a reliable predictor of mortality, Professor Wahlqvist said, but one that opened up the potential for helpful intervention. “Poor appetite may be a valuable early indicator of incipient nutritionally related disorders and disease, and of premature mortality.”

Poor appetite does not directly bring about death. I’s the resulting poor diet that causes the harm.

“Knowledge of old people’s appetite therefore has considerable potential to be useful in both clinical and community settings, and should be part of an integrated approach to diet that underpins a healthy old age,” Professor Wahlqvist said.
