This is the official resource for any health professionals working with young people with eating disorders in the UK. It has been developed by the Junior Marsipan group. It contains 3 things: 1. The full published Junior Marsipan guidance 2. The Junior Marsipan 'Risk Assessment Tool' to evaluate physical risk in malnourished children with eating disorders - know when to worry, and what to do. 3. A percentage median BMI calculator. Just enter the date of birth, weight and height and the calculator will report the young person's BMI, the %mBMI and target weights against the data on which the UK growth charts are based. It will report centiles and standard deviation scores too. Note that this is for health professionals only and therefore requires an Unlock Code for first use. This can be obtained after downloading from the clinician area at www.marsipan.org.uk
