Weight Loss: Waiting to Shed Excess Pounds Does Not Increase Health Risks

Overweight children who wait until adulthood for w are not more likely to face a higher risk of obesity-related health problems, an analysis of four studies involving children and adults in the United States, Australia and Finland suggests, according to Reuters Health.

While the findings don't prove weight loss in itself will eliminate the extra risks, they do show that overweight or obese children are not automatically doomed to have higher rates of diabetes, high blood pressure and heart disease.

"There is hope for overweight and obese children," chief author Dr. Markus Juonala at the University of Turku told Reuters Health in a telephone interview. "If they manage to become non-obese adults, then the risks of these outcomes — diabetes, hypertension, early atherosclerosis — are quite similar to those who have been normal weight all their lives. I think that's quite a positive message."

"It's been thought that if you're an obese kid, it's all done," Juonala added.  "But based on these findings what really matters is what you are at as adult."

At the start of the studies, 12 percent of the children were overweight or obese, and two percent were obese. By adulthood, those figures had increased to 55 percent and 21 percent, respectively.

The analysis also confirmed what doctors have been saying for years — that being an overweight adult increases your risk of developing various health problems. Compared to those who were normal-weight in both childhood and adulthood, obese adults who had been heavy as kids as well faced the highest risks. About seven percent of them had type 2 diabetes, 29 percent had high blood pressure and 18 percent had high levels of "bad" or LDL cholesterol. Among those who had never been overweight, only one percent had diabetes, 11 percent had high blood pressure and nine percent had high-risk levels of bad cholesterol. All of these problems increase the risk of developing heart disease. "If we want to reduce the incidence of adult heart disease and thereby start to control the continuing escalation in U.S. health care expenditures," Dr. Albert Rocchini of the University of Michigan said in an editorial, "now is the time to do whatever it takes to develop more effective methods for both the prevention and the treatment of childhood obesity." This study was published in the New England Journal of Medicine
