Although a lot of attention is devoted to undernutrition, obesity, defined as a BMI of greater than 30, or 20% greater than ideal body weight, is also an independent risk factor for functional decline in the elderly. Women have a higher prevalence of functional decline than men at the upper end of the BMI categories (three times greater risk at a BMI of greater than 35), independent of the usual factors, such as depression and polypharmacy (Jensen & Friedmann 2002).
