 Important elements of history for childhood obesity

Questions
A. Plot the “obesity trajectory”1. Birth weight
2. Early feeding history
3. Whether onset of obesity was sudden or gradual and age of onset of obesity
4. Whether progression of obesity was gradual or rapid
5. Whether there have been any periods of very rapid weight gain, particularly recently
6. Whether there have been any periods of weight loss (and why and how)
7. Who else in the family is obese or has trouble controlling their weight
B. Assess family risk profileTo place the child in the appropriate risk category it is useful to ask about family history (in first and second generations) of components of the insulin resistance syndrome, e.g.:
1. Morbid obesity
2. Type 2 diabetes
3. Hypertension
4. Dyslipidaemia
5. Polycystic ovarian syndrome
6. Early cardiovascular disease (defined as relatives who developed cardiovascular disease in the fifties or earlier)
C. EthnicityNote the ethnic background of the child or adolescent, as those from a Black or South Asian background have a higher risk of the insulin resistance syndrome and diabetes
