 子どもを生涯肥満へと向かわせる「ターニング・ポイント」はしばしば2才前に起こるという。100人以上の肥満の子どもの研究によれば、半数以上は24ヶ月時に体重増加あり、5才時には90%が体重増加である。生後5ヶ月前に1/4は体重増加になっている。
 英国では太りすぎの子どもが今や約27%いる。
 小児の肥満は最新の統計データでは増加していないが高止まり状態にある。

Obesity 'often set before age of two'

More than a quarter of children in Britain are overweight

The "tipping point" that sets children on the way to a lifetime of obesity often occurs before the age of two, say US researchers.
A study of more than 100 obese children and teenagers found more than half were overweight by 24 months and 90% were overweight by the age of five.
A quarter were overweight before they were five months old, the researchers reported in Clinical Pediatrics.
In the UK, around 27% of children are now overweight.
The children in the study - who had an average age of 12 - were all overweight or obese by the age of 10.

Getting parents and children to change habits that have already taken hold is a monumental challenge fraught with road-blocks and disappointments
Dr John Harrington, study leader

Although the reason for rapid weight gain in early life is not well understood, contributing factors are likely to be poor diet, early introduction of solid food, and not getting enough exercise, the researchers said.

Eating behaviour

They added that food preferences may be set by the age of two, so changing a child's eating behaviour at a later stage may be difficult.
Study leader Dr John Harrington, an assistant professor at Eastern Virginia Medical School, said the results should be a "wake-up call for doctors".
He went on: "Too often, doctors wait until medical complications arise before they begin treatment.
"Getting parents and children to change habits that have already taken hold is a monumental challenge fraught with road-blocks and disappointments.
"This study indicates that we may need to discuss inappropriate weight gain early in infancy to effect meaningful changes in the current trend of obesity."
A Department of Health spokesman said: "What happens in the first years of a baby's life has a big effect on how healthy they are in the future.
"Despite recent encouraging statistics which show that childhood obesity may be levelling off, obesity levels are still too high and it is important we keep the mom
entum going."

Abstract
According to the National Health and Nutrition Examination Survey in 2007, nearly half of all American children are either overweight or obese. Retrospective chart review identified patients with the diagnostic codes for overweight, obese, and/or excessive weight gain. Inclusion criteria were current age between 2 and 20 years, a minimum of 5 visits with weight and height measurements, and a body mass index (BMI) at or above the 85th percentile. A total of 184 patients met inclusion criteria. More than half the children became overweight before age 2, and all patients were obese or overweight by age 10. The rate of gain is approximately 1 excess BMI unit/year, therefore causing most children to be overweight by age 2 (R2 = .53). This study indicates that the critical period for preventing childhood obesity in this subset of identified patients is during the first 2 years of life and for many by 3 months of age.
