Accuracy of comparing bone quality to chocolate bars for patient information purposes: observational study

摘要

>Objective To test whether standard information for patients using Crunchie and Aero chocolate bars to explain bone health and risk of fracture is robust.>Design Observational study.>Setting Domestic kitchen in rural west Wales.>Participants 10 Crunchie bars and 10 Aero bars.>Main outcome measure Fracture after falls from varying heights.>Results Both Crunchie and Aero bars exhibited the same T and Z scores for bone density. Crunchie bars had a lower chocolate mass index than the Aero bars. Crunchie bars are more liable to fracture.>Conclusions Using Crunchie and Aero chocolate bars to explain bone structure to patients may be visually attractive but oversimplifies the situation.
