Predicting the Risk of Mobility Difficulty in Older Women With Screening Nomograms The Women’s Health and Aging Study II

Background: A major obstacle to screening for early mo-bility disability (ie, mobility difficulty), a major public health concern, is the lack of a method that identifies those who are at high risk. The goal of this study was to de-velop easy-to-use clinical nomograms for estimation of the probability of incident mobility difficulty. Methods: We conducted a population-based prospec-tive study using data from 266 high physically and cognitively functioning older women, aged 70 to 80 years, who were free of mobility disability at the base-line evaluation of the Women’s Health and Aging Study II. The outcome measure was incident mobility disability within 18 months, defined as self-reported difficulty walking 0.8 km, climbing 10 steps, or trans-ferring from or into a car or bus.
