Pudgy toddlers face a good chance of becoming overweight 12-year-olds, according to government research that shoots down the notion that kids just naturally outgrow early chubbiness.

Children who were overweight at age 2 or later during their preschool years faced a five times higher risk of being overweight at age 12 than youngsters who were not overweight early on, the study found. Sixty percent of the children who were overweight at any time during the preschool period were overweight at age 12.

Children were considered overweight if their body-mass index was in the 85th percentile or higher for their gender and age. That means they were heavier than at least 85 percent of children their same age and sex.

"These results suggest that any time a child reaches the 85th percentile for BMI may be an appropriate time for intervention," the researchers wrote.

"These findings underscore the need to maintain a healthy weight beginning in early childhood. Contrary to popular belief, young children who are overweight or obese typically won't lose the extra weight simply as a result of getting older," said Dr. Duane Alexander, director of the National Institute of Child Health and Human Development, which funded the study.

The researchers also found that 40 percent of children whose BMIs were between the 50th and 84th percentiles by age 3 - or in the normal to high-normal range _ were overweight at age 12. By contrast, no children with a body-mass index below the 50th percentile throughout elementary school had become overweight by age 12.
