This risk calculator predicts low and very low bone mineral density (BMD) among adult survivors of childhood cancer. Low BMD was defined as a BMD Z-score less than -1.0, and very low BMD as a BMD Z-score less than -2.0. This risk calculator uses information from the paper “Prediction of Low and Very Low Bone Mineral Density Among Adult Survivors of Childhood Cancer” (van Atteveld et al. 2019), in which clinically applicable prediction models for low and very low BMD on the basis of easily obtainable predictors were developed in the St. Jude Lifetime cohort and validated in a single center Dutch cohort.
To determine the risk of low and very low BMD for an individual adult childhood cancer survivor, please enter the information below:
