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 mobility 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 develop easy-to-use clinical nomograms for estimation of the probability of incident mobility difficulty . METHODS We conducted a population -based prospect i ve 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 baseline 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 transferring from or into a car or bus . Logistic regression and receiver operating characteristic curve analyses were used for evaluation of the optimal combination of self-reported and performance-based mobility measures . Bootstrap sampling and estimation was used for validation . RESULTS Predictive nomograms were developed based on a final model that included 3 simple-to-obtain measures of pre clinical disability : self-report of modification in mobility tasks without having difficulty with them , one-leg stance balance , and time to walk 1 m at a usual pace . Final model accuracy ( as estimated by the area under the receiver operating characteristic curve ) was 73 % ( SE = 0.04 ) . Validation analysis confirmed the high accuracy of these nomograms . CONCLUSIONS An original tool was developed for assessment of the risk of mobility difficulty in older women that can be used to assist physicians and research ers in deciding which women to target for preventive interventions
