It has also changed significantly over time. Most of this extra food energy came from an increase in carbohydrate consumption rather than fat consumption. In the United States, subsidization of corn, soy, wheat, and rice through the U. Obese people consistently under-report their food consumption as compared to people of normal weight.

We believe that there is little to be gained by arguing with Roland Auer and colleagues about whether diet or physical inactivity is the most important variable leading to obesity in Canadian children: We advocated both healthy nutrition and physical activity throughout our paper. Finally, significant problems exist in assessing physical activity and energy intake, and current techniques are clearly inadequate.

In response to Murray Finkelstein, in our study we used data derived from stratified random samples of the Canadian population.

Our analyses used the design weights provided by Statistics Canada, which take into account the stratified sampling design as well as potential bias due to nonresponse. We agree that this more complex approach is preferable, but note that its use has no appreciable effect on our results or conclusions.

The bootstrap method suggested by Finkelstein is computationally intensive and has some undesirable properties.

Among children aged five to 11, the percentage of obese boys ( per cent) was more than three times that of obese girls ( per cent), the agency said. Obesity rates among children and youth in Canada have nearly tripled in the last 30 years. Children and youth who are obese are at higher risk of developing a range of health problems, and weight issues in childhood are likely to persist into adulthood.

For surveys such as these, which are derived from stratified samples and where individuals are clustered within higher level units such as families or schools, approaches based on balanced repeated replications provide a simple, robust approach to estimate sampling variances 8 and are generally preferable to bootstrap techniques.

We agree with Katzmarzyk about the value of these new definitions. We believe the important finding in our study is that the prevalence of childhood overweight or obesity, however defined, is increasing rapidly. Katzmarzyk points out that when using the method proposed by Cole and colleagues, 13 the magnitude of the problem may be smaller than we reported, but the rate of change of the problem may in fact be larger than we reported.

Abstract. The majority of US youth are of healthy weight, but the majority of US adults are overweight or obese. Therefore, a major health challenge for most American children and adolescents is obesity prevention—today, and as they age into adulthood.
