Not eating enough in hospital: Risk factors are the same all over the world

The researchers from MedUni Vienna have now investigated the factors (and their pattern) that influence the food intake of patients on a specific day, Nutrition Day, and the healthcare structures that are relevant to nutrition in 91,245 hospitalized patients throughout the world and have published the results in the leading magazine The American Journal of Clinical Nutrition.

The central finding: the factors of "reduced mobility", "unintentional weight loss" and "patient has not eaten enough over the previous week" signify an increased risk of eating less. Women are more frequently affected than men and very young and very old people more so than people aged between 40 and 79 years. These four factors are practically of equal importance everywhere – even in the USA where patients generally come into hospital with a higher Body Mass Index. The pattern is always the same: illness goes hand-in-hand with a reduced appetite. 

Schindler: "If any one of these factors is identified, alarm bells should ring."  The eating patterns of these patients should be monitored and they should be supervised and advised, say the MedUni Vienna experts. "The excuse that patients often give that "I am ill so I'm not eating," or even "that's good, at least I'm losing weight" are not acceptable and are bad for their prognosis. These risk groups need special attention."

This special attention must be incorporated into the holistic treatment plan. Schindler: "Firstly patients' eating behaviour should be systematically evaluated on admission to hospital. The simple questions are quick to ask and easy to answer. It should be explained to patients why it is important to eat. It might also be worth considering structural adaptations, such as the possibility of offering smaller portions or highly nutritious snacks between meals or special individual meals. In addition to that, it can be helpful to involve relatives in encouraging them to eat."
