Hospital patients’ poor food intake is putting their health and lives at risk, study shows

For the 36 million Americans hospitalized each year, adequate nutrition plays a critical role in their health and recovery. Yet research from nutritionDay in the U.S., in collaboration with Abbott, shows malnutrition is still an unaddressed and widespread problem in hospitals. The study, published in The Journal of Parenteral and Enteral Nutrition, is the most robust analysis of malnutrition in the U.S. to date. The data confirmed 1 in 3 hospitalized adults are at risk of malnutrition and showed patients’ subpar food intake is putting their health and lives at risk too, reaffirming the need to focus on nutrition.

Using data from nutritionDay – an organization that leads a one-day survey of nutritional factors and food intake in hospitalized adult patients – the researchers looked at nearly 10,000 patients from 245 U.S. hospitals. They assessed the prevalence of malnutrition risk and the impact of food intake, and found:

  1. Nearly half of infectious disease and long-term care patients and more than 40 percent of oncology patients were at risk of malnutrition.

”Malnutrition can be invisible to the eye and is rampant in U.S. hospitals because it’s not always top of mind – symptoms, like decreased energy and unintentional weight loss, can often be attributed to a patient’s primary diagnosis,” said Gail Gewirtz, M.S., R.D., president and founder of nutritionDay in the U.S. ”However, our data shows that one warning sign – poor food intake – is very common in hospitals, and this is something healthcare providers can easily look out for and address.”


Malnutrition occurs when the body doesn’t get the nutrients it needs and can happen in both underweight and overweight individuals. Malnutrition can increase patients’ risk of complications and delay recovery. Often patients arrive to the hospital either malnourished or at risk, and poor food intake while hospitalized can cause further complications and delay recovery.

”Patients don’t always have the best appetite or desire to eat while in the hospital, so it’s important to create an environment and serve up options that promote optimal food intake,” said Abby Sauer, M.P.H., R.D., a registered dietitian at Abbott and lead study author. ”Numerous studies confirm that nutrition care, including a supplemental nutrition drink, can help malnourished patients and those at risk get the nutrients and energy they need to avoid complications, recover and get out of the hospital faster.”

Steps can be taken by healthcare providers, caregivers and patients to reverse the malnutrition trend:

  1. Be your own nutrition advocate: Talk with your healthcare professional about your nutrition needs and ask to speak with a dietitian to make sure you are getting proper nutrition while in the hospital and post-discharge.
