Newswise — Hospital stays of obese patients increased by 112 percent between 1996 and 2004, rising from 797,000 to 1.7 million, according to a new report by HHS' Agency for Healthcare Research and Quality. The federal study looked at the hospital stays of patients who were admitted for their obesity and the stays of obese patients hospitalized for other diseases.

The findings relating to patients admitted to the hospital for treatment of obesity include:

"¢ These patients had 126,000 hospital stays and most were admitted for gastric bypass or other weight loss surgery; and more than half were 18 to 44 years old ; the remaining patients were primarily ages 45 to 64. Women accounted for about 82 percent of all patients admitted for treatment of their obesity.

"¢ Almost all the patients hospitalized for treatment of obesity were morbidly obese, meaning they weighed at least two times more than their ideal weight.

"¢ Hospital costs for patients admitted for obesity treatment were an average of $11,700 per stay.

The findings related to obese patients who were admitted to the hospital for other treatments include:

"¢ They were admitted for other diseases accounted for the roughly 1.6 million other hospital stays. The greatest proportion " 7 percent " was hospitalized for hardening of the arteries. Other leading conditions included congestive heart failure, osteoarthritis, skin infections, depression, diabetes and chronic obstructive pulmonary disorder. Obese patients had higher rates of these conditions than non-obese patients.

"¢ Nearly three-quarters of these patients were over 45 years of age, 64 percent were women, and about one-third were morbidly obese.

"¢ Treating these patients cost hospitals an average of $8,800 per stay.
