Obesity Can Reduce Risk of Developing Pressure Ulcers

In a recent study published in the Journal of Gerontology: Medical Science, researchers suggest that obesity reduces the risk of developing pressure ulcers in hospitalized older adults. A total of 3214 patients admitted to 2 Philadelphia, PA, hospitals between 1998 and 2001 were assessed for risk factors for pressure ulcers. The goal of the investigation was to evaluate the chances of developing a pressure ulcer in both underweight and obese patients, relative to optimal weight patients. Patients enrolled in the study who were underweight demonstrated greater odds of developing a pressure ulcer (adjusted odds ratio [OR] = 1.8; 95% confidence interval [CI], 1.2-2.6). Study participants who were obese had reduced odds (adjusted OR = 0.7; 95% CI, 0.4-1.0), and those with severe obesity had the lowest odds of developing a pressure ulcer (adjusted OR = 0.1; 95% CI, 0.01-0.6). The investigators concluded that extra body fat lowers the risk of pressure ulcers in hospitalized older adults.
