Parental perception of child obesity

There is a known disconnect between when parents recognise obesity in their own child, and how experts define obesity based on objective measurements of height and weight (expressed as age-specific BMI centiles). The *expert* BMI cut offs, typically used in the UK, are based off the centile points at which obesity is assumed to have a negative impact on health (either now or in the future) from a distribution of BMIs representative of children in the early 1990's. This is why a histogram of BMI centiles of children now will not be centred on the 50th centile - as much more than half of kids today have a BMI centile above 50.
