Scottish youngsters are among the fattest in the developed world, according to new figures.
Italy and Malta are the only countries with a higher number of overweight children, an NHS
Scotland report reveals.
One in five 12-year-olds in Scotland are clinically obese - double the
previous estimate - the figures show.
This compares with England and Wales and America, where one in seven
15-year-olds are obese, the Scottish Executive's health watchdog found.

The report also reveals that one in 10 Scots children aged 12 are classed as
severely obese and one in three are overweight.
This compares with France and Sweden, where only 18% are overweight and
Germany, where the figure is 15%.
In the Netherlands 13% of children are overweight and in Slovakia the figure
is 10%, according to the research.
The figures reveal a far worse obesity problem than was indicated in a
previous study, which found just one in 10 Scots primary school pupils to be
obese.
The Clinical Outcome Indicators report by NHS Quality
Improvement Scotland, focuses on obesity rates in children of secondary school
age.
The chief medical officer for Scotland said that the obesity epidemic was down
to life choices.
Dr Mac Armstrong said: "The report highlights serious problems. It's not so
much a wake-up call as an alarm bell which every single one of us should heed.
"Issues like obesity and smoking during pregnancy are fundamentally about
people and the choices they make as individuals and parents.
"We can only reduce the levels of obesity if people make the choices that
promote their own health."
The Scottish Executive launched a multi-million pound healthy eating campaign
in January to try to tackle the obesity epidemic.
But less than 1% of Scots have contacted the healthy living helpline in the
nine months following its launch.
